Navigating the Danish Business Authority for Sole Proprietorships

Starting a business as a sole proprietor in Denmark can be an exhilarating yet challenging endeavor. As a sole proprietor, you enjoy the flexibility and autonomy of being your own boss, but this autonomy also comes with responsibilities that you must navigate through the Danish Business Authority (Erhvervsstyrelsen). Understanding how to effectively interact with this organization is critical for your success. This article aims to provide you with unique insights and detailed instructions on navigating the Danish Business Authority, from registration to compliance, tax obligations, and everything in between.

What is a Sole Proprietorship?

A sole proprietorship, known in Danish as "enkeltmandsvirksomhed", is one of the simplest forms of business structures in Denmark. Sole proprietorships are characterized by the absence of a separate legal entity-the owner and the business are considered one and the same. This structure offers several advantages, including:

1. Ease of Setup: Minimal registration requirements and documentation.

2. Total Control: Owners retain complete control and decision-making authority.

3. Tax Simplicity: Profits are taxed as personal income, simplifying tax filings.

However, with these benefits come responsibilities, especially regarding compliance with laws and regulations laid out by the Danish Business Authority.

Understanding the Danish Business Authority

The Danish Business Authority (Erhvervsstyrelsen) serves as a regulatory body overseeing business activities in Denmark. It is responsible for ensuring that businesses operate within the framework of Danish law. Key functions of the authority include:

- Business Registration: Assisting in the registration process for new businesses.

- Regulatory Compliance: Ensuring that businesses meet legal obligations.

- Statistical Reporting: Collecting data on business activities for economic analysis.

- Business Support: Providing guidance and resources for entrepreneurs.

For sole proprietors, navigating the Danish Business Authority is vital for smooth operation and legal compliance.

Steps to Register a Sole Proprietorship

Registering a sole proprietorship in Denmark is a streamlined process, but it still involves specific steps that must be carefully followed.

1. Determine Your Business Name

The first step in the registration process is deciding on a business name. Your business name should be unique, not misleading, and should reflect the nature of your services or products. To avoid future complications, verify that your chosen name is not already in use by searching the name database available on the Danish Business Authority's website.

2. Obtain a CPR Number

Before you register your business, ensure that you have a CPR (Central Person Register) number. This is a personal identification number assigned to every resident in Denmark, including entrepreneurs. The CPR number is used for identification in all official matters and is crucial for tax purposes.

3. Register Online

Once you have your CPR number and a business name, you can proceed with the online registration process through the Danish Business Authority's website. The registration form requires key information such as:

- Your CPR number

- Business name

- Business address

- Date of commencement

By completing the online form, you can register your business quickly and efficiently, typically receiving your business registration number on the same day.

4. Registration Fees

As a sole proprietor, there are typically no registration fees to establish your business. However, make sure to review any applicable fees for additional services such as VAT registration or operating permits.

5. VAT Registration (If Required)

Depending on your expected revenue, you may also need to register for Value Added Tax (VAT). The threshold for mandatory VAT registration is DKK 50,000 in taxable sales over a 12-month period. If you expect to exceed this threshold, you must register for VAT through the Danish Business Authority.

Compliance and Reporting Obligations

Once your business is registered, you must adhere to various compliance and reporting obligations to ensure that you remain in good standing with the Danish Business Authority.

1. Accounting Records

You are required to maintain accurate accounting records of your business transactions. This includes sales invoices, receipts, and any other financial documents. While sole proprietors are not required to conduct an external audit, it is advisable to implement strong bookkeeping practices to support your financial transparency and ease the tax filing process.

2. Annual Reporting

Sole proprietors must submit an annual tax return to the Danish Tax Agency (Skattestyrelsen). Your income will be taxed as personal income, and it's important to keep your records organized to facilitate this process. You will report your income, expenses, and net profit or loss through a standardized tax form.

3. Compliance with Labor Laws

If you decide to hire employees, you will need to comply with Danish labor laws. This includes registration with the Danish Agency for Labour Market and Recruitment (STAR) and adhering to regulations concerning employee rights and benefits, including pensions, holiday pay, and working conditions.

4. Compliance with GDPR

If your sole proprietorship collects personal data from customers, compliance with the General Data Protection Regulation (GDPR) is essential. You must have a clear privacy policy and obtain consent from customers for data collection.

Exploring Business Support Resources

Starting and running your sole proprietorship can be overwhelming, but there are numerous resources available to assist you on your journey.

1. Danish Business Authority's Tools and Guides

The Danish Business Authority offers various online tools, templates, and guides designed to simplify the process of starting and managing your business. These resources can provide essential information on compliance, registration, and tax obligations.

2. Business Development and Support Organizations

There are numerous business development organizations in Denmark, such as the Danish Chamber of Commerce (Dansk Erhverv) and the Danish Business Development Authority (Innovationsfonden), that offer support, guidance, and funding opportunities for entrepreneurs. These organizations can offer advice and act as a support network to help you navigate challenges.

3. Networking Opportunities

Building a network of contacts within your industry and other business owners can be invaluable. Many organizations host networking events and workshops that can enable you to connect with like-minded individuals.

Taxation for Sole Proprietors

Understanding your tax obligations is a crucial aspect of running a sole proprietorship. The Danish tax system operates on a progressive scale, and as a sole proprietor, your income tax will be aligned with your personal income tax rate.

1. Personal Income Tax

As a sole proprietor, your business income is reported on your personal tax return. The income is taxed according to the general rules of personal taxation in Denmark. Rates may vary based on your income level and can range from 12% up to over 55% depending on your total income.

2. VAT Taxation

If your business requires VAT registration, you will need to charge VAT on your products and services. The standard VAT rate in Denmark is currently 25%. You will also be able to reclaim VAT on business expenses, provided these expenses are VAT-deductible.

3. Provisional Taxes

Sole proprietors are responsible for paying provisional taxes based on estimated profits. These payments are made in advance and adjusted annually once final income has been determined. Be prepared for this by keeping comprehensive records to accurately assess your earnings.

Ensuring Success as a Sole Proprietor

Navigating the landscape of business ownership as a sole proprietor requires diligence and adherence to regulations. Here are some additional tips for ensuring success:

1. Create a Business Plan

Having a clear business plan will guide you through the various stages of your business. Outline your business goals, target market, financial projections, and marketing strategies. This plan will serve as a roadmap for your sole proprietorship.

2. Invest in Marketing Your Business

To grow your business, focus on marketing strategies tailored to your audience. Taking advantage of social media platforms, Google Ads, and local networking can help build your brand awareness and attract customers.

3. Utilize Technology

Leverage technology to streamline your operations. Consider using accounting software, customer relationship management (CRM) tools, and e-commerce platforms to enhance your business efficiency.

4. Stay Informed and Adaptable

Business climates change, and staying informed about market trends and regulations can help you adapt to challenges and seize new opportunities. Regularly monitor updates from the Danish Business Authority and economic news to remain proactive in your business practices.

Choosing the Right Business Structure vs. Sole Proprietorship in Denmark

Before you register a sole proprietorship with the Danish Business Authority, it is worth checking whether this is really the best structure for your situation. In Denmark you can operate as a sole proprietor (enkeltmandsvirksomhed), a personally owned small business (personligt ejet mindre virksomhed – PMV), a private limited company (Anpartsselskab – ApS) or a public limited company (Aktieselskab – A/S). Each form has different implications for liability, taxation, capital requirements and administrative workload.

Key features of a sole proprietorship in Denmark

A sole proprietorship is the simplest and most common form for freelancers, consultants and small traders. You and the business are legally the same person. There is no minimum start-up capital and you can usually register quickly via Virk.dk.

The main characteristics are:

• Unlimited personal liability: All business debts and obligations are your personal responsibility. Creditors can claim against your private assets, including savings and, in some cases, your home.
• Taxation as personal income: Business profit is taxed as your personal income under the Danish income tax system. You can choose between ordinary personal taxation and the business tax scheme (virksomhedsordningen) if you meet the conditions.
• No share capital requirement: You do not need to contribute a fixed minimum capital. This makes it easy and inexpensive to start.
• Simpler administration: Accounting and reporting are generally less complex than for companies, although you must still keep proper records and comply with VAT and tax rules.

When a sole proprietorship is usually a good fit

A sole proprietorship is often suitable when:

• You are starting on a small scale, for example as a freelancer, consultant, craftsman or online seller
• Your risk level and need for external financing are low
• You do not plan to have multiple owners or investors
• You want a simple structure with minimal start-up costs and formalities

Because profits are taxed as personal income, a sole proprietorship can be tax-efficient at lower income levels and in the early years of a business. However, as profits grow, the lack of separation between you and the business can become a disadvantage both in terms of risk and taxation.

Comparing sole proprietorship with PMV (personligt ejet mindre virksomhed)

A PMV is a special form of personally owned business aimed at very small activities. It is still a sole owner structure with unlimited personal liability, but with some limitations and simplifications.

Key points to consider:

• Turnover limit: A PMV may not have an annual turnover exceeding 50,000 DKK over a 12‑month period. If you exceed this, you must convert to a regular sole proprietorship and, if relevant, register for VAT.
• VAT registration: As long as you stay below the 50,000 DKK turnover threshold in any 12‑month period, you are not required to register for VAT. Once you expect to exceed this limit, VAT registration becomes mandatory.
• Employees: A PMV cannot have employees. If you plan to hire staff, you must choose a regular sole proprietorship or a company form.
• Administration: PMV registration is simple and designed for hobby-like or test-phase activities, but you still need to keep basic accounts and report income in your personal tax return.

PMV can be a good way to test a business idea with very low turnover and no employees. If you already expect higher turnover or want to grow, registering directly as a sole proprietorship is usually more appropriate.

Comparing sole proprietorship with ApS (private limited company)

The most common alternative to a sole proprietorship is a private limited company (ApS). An ApS is a separate legal entity with limited liability, but it requires more capital and administration.

Important differences include:

• Liability: In an ApS, your liability is limited to the company’s capital. As a rule, your private assets are protected if the company cannot pay its debts, unless you have provided personal guarantees or acted negligently. In a sole proprietorship, liability is unlimited.
• Minimum share capital: To establish an ApS you must contribute at least 40,000 DKK in share capital, either in cash or in kind. A sole proprietorship has no minimum capital requirement.
• Taxation: An ApS pays corporate tax on its profits. The corporate tax rate in Denmark is 22%. After tax, profits can be retained in the company or distributed as dividends, which are then taxed at shareholder level. In a sole proprietorship, all profit is taxed directly as your personal income, potentially at higher marginal rates when income is high.
• Owner remuneration: As the owner of an ApS, you can pay yourself a salary (taxed as personal income) and/or dividends (taxed as share income). This gives more flexibility in tax planning compared with a sole proprietorship, where all profit is treated as business income under the personal tax system.
• Administration and costs: An ApS must comply with company law requirements, including formal annual financial statements and registration of management and ownership. Accounting, auditing (in some cases) and legal obligations are more extensive than for a sole proprietorship.

An ApS is often preferable if you expect significant profits, want to reinvest earnings in the business, need investors or partners, or operate in a sector with higher financial or contractual risk. The limited liability can be a decisive factor if you sign large contracts, take loans or have employees.

Comparing sole proprietorship with A/S (public limited company)

An A/S is typically used for larger businesses with multiple shareholders and greater capital needs. For most small and medium-sized entrepreneurs, the choice is between a sole proprietorship and an ApS, but it is useful to understand the main differences.

Key features of an A/S include:

• Minimum share capital of 400,000 DKK
• Stricter corporate governance rules, including a board of directors or supervisory board
• Possibility to raise capital from a broader group of investors
• Limited liability similar to an ApS

Due to the higher capital requirement and more complex regulation, an A/S is rarely the first choice for a new small business. It may become relevant later if the company grows significantly and needs more advanced financing or governance structures.

Tax considerations when choosing a structure

In a sole proprietorship, your business profit is included in your personal income and taxed according to the Danish personal tax system, which includes municipal tax, state tax and labour market contributions. At higher income levels, your marginal tax rate can exceed the 22% corporate tax rate that applies to ApS and A/S.

However, sole proprietors can use schemes such as the business tax scheme (virksomhedsordningen) if they meet the conditions. This can allow you to:

• Deduct interest expenses more favourably
• Retain part of the profit in the business at a lower preliminary tax rate
• Smooth out income between years to reduce the impact of fluctuating profits

Despite these options, once your stable annual profit reaches a higher level, it can be beneficial to compare the total tax burden and risk profile of a sole proprietorship with that of an ApS. The optimal choice depends on your total income, private finances and long-term plans.

Risk, growth and investor considerations

Liability and growth plans are often the deciding factors between a sole proprietorship and a company form:

• If you operate with low financial risk, few long-term contracts and no employees, a sole proprietorship is usually sufficient.
• If you plan to take on significant loans, sign large contracts, handle substantial customer prepayments or operate in a sector with higher risk of claims, the limited liability of an ApS can protect your private assets.
• If you want to bring in partners or investors, a company structure with shares (ApS or A/S) is usually necessary. A sole proprietorship cannot issue shares and is always owned by one person.

Practical criteria to help you choose

When deciding between a sole proprietorship and other structures, consider:

1. Expected annual turnover and profit: Lower and more uncertain income often points to a sole proprietorship or PMV. Higher and more stable profits may justify an ApS.
2. Risk level: The higher the financial and legal risk, the stronger the argument for limited liability.
3. Capital needs: If you need external investors or significant financing, a company form is usually more suitable.
4. Administrative capacity: If you prefer minimal formalities and lower accounting costs, a sole proprietorship is simpler.
5. Long-term plans: If you expect to grow, hire employees and expand internationally, starting with an ApS can make future development easier.

Choosing the right business structure at the start can save you both tax and legal complications later. If you are unsure, it is often wise to begin with a sole proprietorship or PMV and then reassess the structure as your turnover, risk and financing needs increase. Professional accounting and legal advice can help you compare concrete scenarios and choose the form that best supports your business strategy in Denmark.

Digital Registration via Virk.dk: A Step-by-Step Walkthrough

In Denmark, almost all business registrations are handled digitally through the Danish Business Authority’s self-service portal at Virk.dk. If you want to start a sole proprietorship (enkeltmandsvirksomhed), you must create and submit your registration online. Below you will find a practical, step-by-step walkthrough of the process, from preparing your digital IDs to receiving your CVR number.

1. Prepare your digital tools and information

Before you start the registration on Virk.dk, make sure you have:

• MitID (personal digital ID) – you use this to log in and sign the registration
• Access to your e-Boks – official letters from the Danish authorities, including your CVR confirmation, are sent there
• Your CPR number and Danish address
• A clear idea of your business activity (what you will sell or which services you will provide)
• An idea of your expected annual turnover, especially to decide about VAT (moms) registration

You do not need share capital to start a sole proprietorship, but you should already have a business name in mind and know whether you want to use your own name or a separate trade name.

2. Log in to Virk.dk and find the correct registration form

Go to www.virk.dk and choose the English language version if needed. Then:

1. Click on “Start a business” or search for “Register sole proprietorship”.
2. Select the form for registering an enkeltmandsvirksomhed (sole proprietorship).
3. Log in with your MitID when prompted.

The system automatically links your registration to your CPR number and personal details, so you do not need to enter basic identity information manually.

3. Choose your business name and address

Next, you must enter your business identity details:

• Business name – you can use your own name (for example, “Anna Jensen”) or a trade name (for example, “AJ Consulting”). The name must be unique and must not be misleading or too similar to existing registered names.
• Business address – this can be your home address if you run the business from home. Make sure the address matches the Danish address registered with the authorities.
• Contact details – phone number and email address for business communication.

Check the spelling carefully, as this information will appear in the public CVR register and on official documents.

4. Define your business activity and industry code (NACE/BRANCHEKODE)

You must describe what your business does and select the correct industry code (branchekode/NACE code). This classification is important because it affects:

• Which rules and sector-specific regulations may apply to you
• Whether you need special licenses or approvals
• How statistics and public registers categorize your business

On Virk.dk, you can search for your activity in plain language (for example, “IT consulting”, “hairdresser”, “online shop”) and then choose the most accurate code from the list. If you are unsure, pick the code that best reflects your main source of revenue. You can later update the code if your business changes focus.

5. Decide on VAT (moms) registration and other tax registrations

During the registration, you must decide whether to register for VAT (moms) and possibly other schemes. In Denmark, you must register for VAT if your taxable turnover exceeds DKK 50,000 within a 12‑month period. Many sole proprietors choose to register from the start, especially if they expect to reach this threshold quickly or if they mainly sell to VAT‑registered businesses.

On the Virk.dk form you will typically be asked to:

• Indicate whether you want to register for VAT from the start date of your business
• Specify the expected annual turnover and start date of VAT‑liable activities
• Indicate whether you will be engaged in import/export of goods or services within or outside the EU

If you plan to have employees, you can also register for A‑tax (PAYE) and AM‑bidrag (labour market contribution) as an employer, but many sole proprietors do this later when they actually hire staff.

6. Set the official start date of your business

You must enter the date on which your business activities begin. This date is important because it determines:

• From when you can deduct business expenses
• From when your VAT obligations start (if you register for VAT)
• Which income year your first business income belongs to

The start date can be in the near future, but you cannot backdate the registration arbitrarily. If you have already started trading, choose the earliest realistic date when you began business activities, such as when you first issued an invoice or signed a contract.

7. Review declarations and confirm your responsibility

Before submitting, Virk.dk will show you a summary of the information you have entered. Carefully review:

• Business name and address
• Industry code and activity description
• VAT registration choice and start date
• Any additional registrations (for example, as an employer)

You must then accept the legal declarations confirming that the information is correct and that you understand your obligations regarding bookkeeping, VAT, tax and reporting. This is a good moment to consider whether you want professional accounting support from the beginning to avoid future compliance issues.

8. Sign and submit the registration with MitID

Once you are satisfied with the information, you sign the registration digitally with your MitID. The system sends your application directly to the Danish Business Authority and, where relevant, to the Danish Tax Agency (Skattestyrelsen) for tax and VAT registration.

In most straightforward cases, the registration of a sole proprietorship is processed quickly, often within a short time after submission. You do not pay a registration fee for starting a sole proprietorship.

9. Receive your CVR number and official confirmation

After approval, you receive your CVR number (business registration number). This is sent to your e‑Boks and is also visible in the public CVR register at cvr.dk. The CVR number is essential for:

• Issuing invoices to customers
• Registering for and reporting VAT
• Opening a business bank account (if required by your bank)
• Entering into contracts as a business

Keep the confirmation letter and CVR details safe, as you will need them frequently when dealing with authorities, suppliers and customers.

10. Next steps after digital registration

Registering via Virk.dk is only the first step. After you receive your CVR number, you should:

• Set up a bookkeeping system that meets Danish record‑keeping requirements
• Decide how you will handle VAT reporting periods (usually quarterly for smaller businesses)
• Make sure your e‑Boks is monitored regularly so you do not miss deadlines or letters from the authorities
• Consider engaging a professional accountant to help with tax planning, VAT and annual reporting

By following the digital registration process on Virk.dk carefully and setting up proper accounting routines from day one, you create a solid and compliant foundation for your sole proprietorship in Denmark.

Required Information and Documents Before You Register

Before you start the online registration of your sole proprietorship with the Danish Business Authority (Erhvervsstyrelsen) via Virk.dk, it is important to prepare all the required information and documents. Having everything ready will make the process faster, reduce the risk of errors and help you avoid delays or rejections.

Personal identification details

As a sole proprietor, you and your business are legally the same entity, so the registration is based on your personal data. You will need:

• Your full legal name as registered in Denmark
• Your CPR number (Danish personal identification number)
• Your current residential address in Denmark
• Your email address and mobile phone number for official communication

If you are not a Danish resident but wish to register a sole proprietorship in Denmark, you will normally need a Danish CPR number or a special tax number and must meet the Danish rules on establishment and tax residency. In such cases, additional documentation may be required, and professional advice is strongly recommended.

Digital identification: MitID and e-Boks

Registration is done digitally, so you must have:

• MitID (replacing the former NemID) to log in to Virk.dk and sign the registration
• Access to your e-Boks, where you will receive official letters from the Danish Business Authority and the Danish Tax Agency (Skattestyrelsen)

Without MitID, you cannot complete the online registration. Make sure your MitID is active and that you can log in before you start.

Business name and CVR registration details

When registering, you must provide information about your business identity. Prepare:

• The chosen business name (virksomhedsnavn). Check in advance if the name is already in use or conflicts with existing trademarks.
• Whether you will also use a secondary name or trading name (binavn), if relevant
• The business address in Denmark (can be your home address if allowed by local rules and your lease)
• Your preferred start date of the business (the date from which your activities and tax obligations begin)

Once approved, your business will receive a CVR number (business registration number), which you will use on invoices, contracts and in all communication with public authorities.

Business activity and industry classification

You must describe what your business will do. The Danish Business Authority uses this to assign an industry code (branchekode / NACE code). Prepare:

• A clear description of your main business activity (for example: “freelance graphic design”, “IT consulting”, “online retail of clothing”)
• Any secondary activities you expect to carry out

Choosing the correct industry code is important because it may affect your reporting obligations, statistics, sector-specific rules and, in some cases, licensing requirements.

VAT (moms) and tax-related information

During registration you will be asked about VAT and tax. You should be ready to decide:

• Whether you want to register for VAT (moms) from the start. VAT registration becomes mandatory when your taxable turnover exceeds DKK 50,000 within a 12‑month period, but many businesses choose to register earlier to deduct input VAT on expenses.
• Whether you will have employees and need to register as an employer (for A-tax, AM-bidrag and ATP contributions).

You do not need to upload tax documents at the registration stage, but you must be prepared to provide realistic information about your expected turnover and activity. This will influence your preliminary tax assessment (forskudsopgørelse) with the Danish Tax Agency.

Bank account and payment details

While not always required to complete the initial registration, it is highly recommended to have or plan for:

• A dedicated business bank account in Denmark, separate from your personal account, for incoming payments and expenses
• Access to Nets or other payment solutions if you will accept card payments or direct debits

Some banks may ask for your CVR number before opening a business account, so be prepared for a two-step process: register the business, then open the account and update your invoicing details accordingly.

Address, lease and home‑based business considerations

If you use your home as your business address, check:

• Whether your lease or homeowners’ association rules allow business activities at the address
• Local municipal rules regarding signage, customer visits or storage of goods

If you rent office or warehouse space, keep a copy of your lease agreement. You do not usually upload it during registration, but you may need it for bank, insurance or later documentation.

Licences and sector‑specific approvals

Certain activities require special licences or registrations in addition to the basic registration with the Danish Business Authority. Before you register, verify whether your business falls under any regulated category, for example:

• Food production, catering, restaurants or food retail (registration with the Danish Veterinary and Food Administration)
• Transport services, taxi, freight or passenger transport
• Financial services, insurance mediation or investment advice
• Healthcare professions, beauty treatments involving medical procedures, or childcare services

If a licence is required, gather the necessary documentation (qualifications, insurance, hygiene approvals, etc.) so you can apply immediately after or, where required, before registering your sole proprietorship.

Accounting and record‑keeping setup

Although you do not submit accounting documents when you register, you must be prepared to meet Danish bookkeeping rules from day one. Before registration, it is wise to decide:

• Which accounting system or software you will use (for example, a Danish cloud‑based bookkeeping solution)
• How you will store invoices and receipts electronically for at least 5 years, as required by Danish bookkeeping legislation
• Whether you will work with a professional accountant or bookkeeper to handle VAT returns, annual statements and communication with the authorities

Having this structure in place before you start trading helps you stay compliant and avoid penalties for late or incorrect reporting.

Summary: checklist before you start registration

To streamline your registration with the Danish Business Authority, make sure you have:

• Active MitID and access to e-Boks
• Your CPR number and personal contact details
• Chosen business name and Danish business address
• Clear description of your main activity for industry classification
• Decision on VAT registration and potential employees
• Plan for a business bank account and payment solutions
• Confirmation of any required licences or sector‑specific approvals
• Basic accounting and record‑keeping setup

Preparing these elements in advance will help you complete the online form quickly, reduce the risk of mistakes and ensure that your Danish sole proprietorship starts on a solid, compliant foundation.

Registering for VAT (Moms) and When It Becomes Mandatory

In Denmark, VAT (moms) is a consumption tax that most businesses must charge on the goods and services they sell. As a sole proprietor, understanding when you must register for VAT and how the system works is crucial to staying compliant and avoiding unexpected tax bills or penalties.

When VAT registration becomes mandatory

You are required to register for VAT with the Danish Business Authority (Erhvervsstyrelsen) when your business meets any of the following conditions:

• Your VAT-liable turnover exceeds DKK 50,000 within any continuous 12‑month period
• You expect to exceed DKK 50,000 in VAT-liable turnover within the next 12 months based on realistic forecasts or signed contracts
• You sell certain services to customers in other EU countries where the reverse charge does not apply and local VAT rules require Danish registration
• You sell digital services to private consumers in other EU countries and choose to use the EU VAT schemes (e.g. OSS) via Denmark

The DKK 50,000 threshold applies to your total VAT-liable sales before VAT, not to your profit. Once you see that you are close to this limit, you should plan registration in advance rather than waiting until you have clearly exceeded it.

What counts towards the DKK 50,000 threshold?

Most ordinary business income is VAT-liable and counts towards the threshold, including:

• Sales of goods in Denmark
• Sales of services such as consulting, design, IT, trades, and similar activities
• Ongoing service contracts and subscriptions

Some types of income are exempt from VAT and do not count towards the DKK 50,000 limit, for example:

• Certain financial services and insurance
• Most health and medical services provided by authorised professionals
• Certain educational services that meet specific criteria

If your business includes both VAT-liable and VAT-exempt activities, you must carefully separate these in your bookkeeping, as only the VAT-liable turnover is relevant for the registration threshold.

Standard VAT rate and special rates

Denmark applies a single standard VAT rate of 25% to almost all goods and services. There are no reduced VAT rates (for example, there is no lower rate for food or books as in some other EU countries). Instead, some areas are fully exempt from VAT, such as many financial, health and educational services.

If your activity is VAT-exempt, you do not charge VAT on your invoices, but you also cannot deduct input VAT on your purchases related to those exempt activities.

How and where to register for VAT

You register for VAT online via the Danish Business Authority’s self-service platform on Virk.dk. When you register your sole proprietorship or update your existing registration, you must indicate that your business is VAT-liable.

During registration you will typically need to provide:

• Your CPR number and MitID for secure login
• Basic business information (name, address, industry code)
• The expected start date of VAT-liable activities
• Estimated annual turnover

Once your registration is approved, your business will receive a CVR number (if you do not already have one) and will be registered as VAT-liable with the Danish Tax Agency (Skattestyrelsen). From the start date you have chosen, you must charge VAT on all relevant sales and report it in your VAT returns.

Charging VAT on your invoices

After registration, your invoices must clearly show:

• Your business name and address
• Your CVR number
• The invoice date and a unique invoice number
• A description of the goods or services supplied
• The net amount (without VAT)
• The VAT rate (25%) and the VAT amount in DKK
• The total amount including VAT

If you issue invoices without VAT after you have become liable, you may still have to pay the VAT to the tax authorities, even if you did not charge it to your customer. Correct invoicing is therefore essential.

VAT periods and filing deadlines

As a sole proprietor, your VAT reporting frequency depends on your turnover:

• Quarterly VAT reporting is the most common for small businesses. You report and pay VAT four times a year.
• Half-yearly VAT reporting may be available for very small businesses with low turnover, if granted by the tax authorities.
• Monthly VAT reporting applies to businesses with higher turnover or specific types of activities.

The Danish Tax Agency assigns your VAT period when you register. Each VAT period has a fixed deadline for filing and payment, typically one month and a few days after the end of the period. You submit your VAT return digitally via TastSelv Erhverv on Skattestyrelsen’s website.

Input VAT deduction

Once registered, you can deduct the VAT you pay on business-related purchases (input VAT) from the VAT you collect from your customers (output VAT). Only the net amount is paid to or refunded by the tax authorities.

To deduct input VAT, the expense must:

• Be directly related to your VAT-liable business activity
• Be documented with a proper invoice that shows the supplier’s CVR number and the VAT amount

Some expenses are only partially deductible (for example, mixed private and business use of a car or phone), and some are not deductible at all, such as most private expenses and certain representation costs. Good bookkeeping and clear separation of private and business expenses are essential.

Voluntary VAT registration below the threshold

You may choose to register for VAT even if your turnover is below DKK 50,000. Voluntary registration can be beneficial if:

• You have significant start-up costs with VAT that you want to deduct
• Your customers are mainly VAT-registered businesses that can deduct the VAT you charge
• You want to appear more established and professional by operating as a VAT-registered business

However, voluntary registration also means additional administrative work and strict reporting obligations, so it should be considered carefully.

Consequences of late or missing VAT registration

If you fail to register for VAT on time, the tax authorities can:

• Register you retroactively from the date your VAT-liable activity started
• Demand payment of VAT for past periods, even if you did not charge VAT to your customers
• Impose interest and possible surcharges on unpaid VAT

In serious or repeated cases, additional penalties may apply. Monitoring your turnover and registering promptly is therefore a key part of managing your sole proprietorship responsibly.

How professional accounting support can help

VAT rules in Denmark are detailed and can be complex, especially if you have mixed activities, cross-border sales or significant start-up investments. A professional accountant can help you:

• Assess when VAT registration is required or advantageous
• Set up correct invoicing and bookkeeping routines
• Optimise input VAT deductions within the rules
• Prepare and submit accurate VAT returns on time

With the right guidance, VAT becomes a manageable part of running your sole proprietorship, rather than a source of uncertainty or risk.

NemID/MitID and e-Boks: Digital Tools You Must Use with the DBA

To run a sole proprietorship in Denmark, you must be able to identify yourself and communicate digitally with public authorities. Two key tools you will use with the Danish Business Authority (DBA) and other authorities are MitID (which has replaced NemID) and e-Boks. Understanding how they work and how they interact with the DBA will save you time and help you stay compliant.

MitID: your digital ID for business and tax

MitID is the standard digital ID used in Denmark for both private and business purposes. You use it to log in to:

• Virk.dk – to register and manage your sole proprietorship with the DBA
• skat.dk – to handle tax, VAT (moms) and advance tax (B-skat)
• Online banking and many private services

As a sole proprietor, you normally use your personal MitID to access Virk.dk and skat.dk, because your business is not a separate legal entity. When you log in with MitID, you can:

• Register your sole proprietorship and obtain a CVR number
• Register or deregister for VAT and payroll taxes
• Update business details such as address, industry code (branchekode) and contact information
• Report changes that must be notified to the DBA

If you plan to give your accountant or another adviser access to handle registrations and reporting on your behalf, you can grant them a digital power of attorney (fuldmagt) via Virk.dk. They will then use their own MitID to act for your business within the permissions you have set.

e-Boks: mandatory digital mailbox for official communication

e-Boks is your secure digital mailbox for messages from public authorities and many private companies. For sole proprietors, e-Boks is the primary channel for receiving official letters from the DBA, the Danish Tax Agency (Skattestyrelsen), municipalities and other authorities.

Once your business is registered and has a CVR number, authorities will normally send all important information to e-Boks instead of by post. This can include:

• Confirmation of registration and changes from the DBA
• Reminders and deadlines for VAT returns and tax filings
• Decisions on registrations, permits or industry-specific approvals
• Notifications about missing information or compliance issues

You are legally expected to read and respond to messages in e-Boks within the stated deadlines. Not checking your e-Boks regularly can lead to missed deadlines, fines or loss of certain rights, even if you never opened the message.

How MitID and e-Boks work together in practice

You access e-Boks using your MitID login. In practice, this means:

• You log in with MitID to Virk.dk to register or update your business with the DBA
• The DBA sends confirmations, decisions and reminders to your e-Boks
• You log in with MitID to e-Boks to read and respond to those messages

Because your sole proprietorship is tied to you personally, your personal e-Boks is typically used for both private and business-related messages from authorities. It is therefore important to:

• Keep your contact details in the Central Business Register (CVR) up to date
• Log in to e-Boks regularly, or activate notifications to your email or phone
• File or forward important business messages to your accounting system or adviser

Setting up and maintaining secure access

To use MitID and e-Boks effectively and securely for your sole proprietorship:

• Ensure your MitID is active and that you have at least one backup method (for example, the MitID app on a second device or a code display)
• Do not share your MitID with employees, family members or business partners – instead, grant them formal access via Virk.dk or e-Boks where relevant
• Review your e-Boks settings so that you receive notifications when new messages arrive
• Organise your e-Boks folders so that business-related messages are easy to find for you and your accountant

Proper use of MitID and e-Boks is not just a technical detail; it is a core part of staying compliant with the DBA and other Danish authorities. Treat these tools as essential components of your daily business administration, on the same level as your bookkeeping and tax reporting.

Industry-Specific Licenses and Registrations with the DBA

Not every sole proprietorship in Denmark can operate on a standard registration alone. Depending on your industry and activities, you may need specific licenses, permits or additional registrations through the Danish Business Authority (Erhvervsstyrelsen) and related authorities. Understanding these requirements before you start trading helps you avoid fines, forced closure or loss of liability protection.

When an industry-specific license is required

Industry-specific rules generally apply when your business:

• Handles food, alcohol, tobacco or pharmaceuticals
• Provides regulated professional services (for example legal, financial or health-related services)
• Works in construction, electrical, plumbing or other safety‑critical trades
• Operates in transport, tourism, childcare or education
• Uses protected titles or activities that require authorisation (for example real estate, insurance or investment services)

Licensing is often handled via Virk.dk and the Danish Business Authority, but in many cases the DBA coordinates with sector regulators such as the Danish Safety Technology Authority, the Danish Veterinary and Food Administration or the Danish Financial Supervisory Authority.

Common sectors with special licensing and registration

Food, cafés, catering and hospitality

If your sole proprietorship produces, sells or serves food or beverages, you must normally register with the Danish Veterinary and Food Administration (Fødevarestyrelsen) before you start operations. This applies to restaurants, cafés, food trucks, catering, bakeries and most online food businesses.

Key points include:

• Food business registration via Virk.dk, usually processed within a few weeks
• Mandatory self‑monitoring (egenkontrol) procedures and documentation
• Compliance with hygiene rules and regular inspections, which result in a public “smiley” rating

If you serve alcohol on premises, you may also need a liquor license from your municipality, in addition to your business registration with the DBA.

Construction, electrical and plumbing trades

Many construction‑related activities require authorisation or registration beyond a simple sole proprietorship setup. Examples include:

• Electrical installations and work on fixed electrical systems
• Gas, water and heating installations
• Certain safety‑critical construction and renovation tasks

Authorisations are typically handled by the Danish Safety Technology Authority (Sikkerhedsstyrelsen). You must document professional qualifications, relevant education and, in some cases, practical experience. Working without the correct authorisation can lead to orders to stop work, administrative fines and liability issues with insurance.

Transport and logistics

If you operate commercial transport of goods or passengers, you may need a special permit or license. This can include:

• Road haulage for third parties above certain vehicle weight thresholds
• Taxi services and limousine services
• Bus and coach operations

Permits are usually issued by the Danish Road Traffic Authority (Færdselsstyrelsen) and local municipalities, but your business must still be correctly registered with the DBA. Requirements often include professional competence, financial standing and good repute.

Financial, real estate and insurance services

Some financial and advisory activities are tightly regulated and may require registration or authorisation with the Danish Financial Supervisory Authority (Finanstilsynet) in addition to your DBA registration. This can apply if you:

• Provide investment advice or manage client funds
• Act as an insurance intermediary or broker
• Offer consumer credit or certain payment services

Real estate agents (ejendomsmæglere) must meet specific education and registration requirements and may need to be listed in public registers. Using protected titles without the required authorisation is prohibited and can trigger enforcement action.

Health, beauty and personal care

Health‑related professions such as doctors, nurses, physiotherapists and psychologists are regulated and require authorisation from the Danish Patient Safety Authority (Styrelsen for Patientsikkerhed). Even if you operate as a sole proprietor, you must hold the correct professional license and comply with sector‑specific rules on patient data, consent and record‑keeping.

Some beauty and personal care services, such as tattooing and piercing, are also regulated. You may need to register your studio, meet hygiene and facility standards and undergo inspections.

Education, childcare and social services

If your business provides childcare, after‑school activities, private schooling or social care services, you will usually need approval from the relevant municipality or national authority. Requirements can include background checks, staff qualifications, safety standards and ongoing supervision. The DBA registration only covers the commercial aspect; it does not replace sector approvals.

How to check licensing requirements via the DBA and Virk.dk

The Danish Business Authority and Virk.dk act as central entry points for many industry registrations. Before you start trading, you should:

• Use the guides on Virk.dk to search for your industry and activity
• Check whether your NACE code (branchekode) triggers special rules
• Review links from the DBA to sector authorities responsible for your field
• Confirm whether you must register before starting, or within a specific deadline after starting

In many cases, the same Virk.dk login you use for your sole proprietorship registration is also used to submit license applications, upload documentation and receive digital decisions in e‑Boks.

Updating and maintaining your licenses

Industry‑specific licenses are not a one‑time task. You must keep them up to date when your business changes. Typical triggers for updating registrations include:

• Changing your business address or opening new locations
• Adding new services or products that fall under different regulations
• Hiring staff whose qualifications affect your authorisation status
• Transferring or closing parts of your business

Some licenses must be renewed periodically or require ongoing documentation, such as updated insurance policies, financial statements or proof of continuing education. Failing to renew on time can result in suspension or withdrawal of your authorisation.

Consequences of operating without the right license

Running a licensed activity without the required approvals can lead to:

• Orders to stop operations immediately
• Administrative fines and, in serious cases, criminal penalties
• Problems with insurance coverage if damage occurs
• Reputational damage, especially when inspection results are public

Because the DBA, tax authorities and sector regulators share information, irregularities can be detected through cross‑checks of your registrations, reported industry codes and tax filings.

How a professional accountant can help

For many sole proprietors, the most efficient approach is to combine legal and sector advice with professional accounting support. An accountant familiar with Danish regulations can:

• Help you choose the correct industry codes and describe your activities accurately
• Identify when additional licenses or registrations are needed
• Coordinate your DBA registration with VAT, tax and sector‑specific obligations
• Set up record‑keeping procedures that satisfy both tax and licensing requirements

By clarifying your licensing obligations early and keeping your registrations aligned with how you actually operate, you reduce regulatory risk and can focus on growing your sole proprietorship within the Danish rules.

Updating Business Details and Handling Changes with the DBA

Once your sole proprietorship is registered with the Danish Business Authority (Erhvervsstyrelsen), you are legally required to keep your business information up to date. Most changes are reported digitally via Virk.dk and are automatically shared with other public systems, such as SKAT (the Danish Tax Agency), the CVR register and, where relevant, Statistics Denmark.

Which changes must be reported to the Danish Business Authority?

You must update the Danish Business Authority whenever key details about your sole proprietorship change. In practice, this typically includes:

• Change of business address or postal address
• Change of owner’s private address (if linked to the registration)
• Change of business name (including introduction or removal of a trading name)
• Change of main business activity (NACE/branchekode)
• Change of contact details (phone, email, website) used for public registers
• Change of accounting period (financial year)
• Start or cessation of VAT (moms) registration
• Start or cessation of registrations for payroll tax (lønsumsafgift), import/export, or other schemes
• Transition from part-time to full-time activity if it affects tax or social security status

Most updates must be reported without undue delay once the change has occurred. Failing to update your details can lead to incorrect tax assessments, missed official communication and, in serious cases, fines.

How to update your business details via Virk.dk

All updates are made online through Virk.dk, using your MitID. The process is similar to the initial registration:

1. Log in to Virk.dk with your MitID as a private person (for sole proprietors).
2. Search for your business by CVR number or name.
3. Select the relevant self-service form, typically “Ændre virksomhed” (Change business).
4. Update the fields that have changed, such as address, activity code or contact details.
5. Confirm and submit the changes. In most cases, updates take effect immediately in the CVR register.

For some changes, such as switching accounting period or changing VAT status, the system may require additional confirmations or effective dates. Always check the confirmation page and save or print the receipt for your records.

Changing business address or contact details

Address changes are among the most common updates. When you move your business to a new location, you must update the address in the CVR register. This is crucial because:

• Authorities use the registered address for official letters and inspections
• Customers and suppliers rely on the CVR register for correct contact information
• Municipal rules (e.g. zoning, environmental permits) may depend on the location

If you run your sole proprietorship from your home, a change of your private address must also be reported if it is linked to the business registration. You should also update your phone number, email and website to ensure that public records and online search results remain accurate.

Changing business name or activity (branchekode)

If you rebrand your business or start offering new core services, you may need to change your registered business name or activity code:

• Business name: You can usually change the name of a sole proprietorship without creating a new CVR number, as long as the owner remains the same. The new name must be unique and not misleading or too similar to existing protected names.
• Activity code (branchekode/NACE): If your main source of revenue shifts to a different activity, you should update the primary activity code. This affects statistics, industry-specific rules and, in some cases, eligibility for support schemes or sector regulations.

When changing your name, remember to update invoices, contracts, website, marketing materials and bank accounts to match the new registered name.

Updating VAT (moms) and other registrations

Your obligations towards the Danish Tax Agency are closely linked to the registrations held by the Danish Business Authority. Typical changes include:

• Registering for VAT: You must register for VAT when your taxable turnover exceeds 50,000 DKK within a 12‑month period, or if you expect to exceed this threshold. The registration is done through Virk.dk and becomes visible in the CVR register.
• Deregistering from VAT: If your activity becomes VAT‑exempt or you permanently fall below the threshold and stop VAT‑liable activities, you must deregister. You will need to submit final VAT returns and settle any outstanding VAT.
• Payroll tax (lønsumsafgift): Certain VAT‑exempt sectors (e.g. financial services, some health services) must register for payroll tax. If you enter or leave such an activity, you must update this registration.
• Import/export and EU trade: If you start trading goods or services with other EU countries, you may need an EORI number and special registrations for EU VAT reporting (e.g. OSS schemes). These are typically initiated via Virk.dk and SKAT’s systems.

Any change in registration status affects your reporting frequency and deadlines, so it is important to coordinate updates with your accounting and bookkeeping routines.

Changing the financial year (accounting period)

Most sole proprietors in Denmark use the calendar year as their financial year, but it is possible to choose a different accounting period in some cases. If you wish to change your financial year, you must:

• Apply the change via Virk.dk, indicating the new start and end dates
• Ensure that the transition period (short or extended year) is clearly reflected in your accounts
• Coordinate with SKAT to align income tax and VAT reporting with the new period

Changing the financial year can have tax implications, especially regarding income timing and deductions. Professional advice is recommended before making this type of change.

Temporary suspension vs. actual closure

Sole proprietors sometimes reduce or pause their activity without fully closing the business. It is important to distinguish between:

• Temporary inactivity: You may keep your CVR number active but have no or very low activity for a period. You must still file required VAT and tax returns, even if they are “zero” returns, unless you have formally deregistered from specific schemes.
• Partial deregistration: You can deregister from VAT, payroll tax or other schemes while keeping the business itself active in the CVR register, for example if you stop selling VAT‑liable services but keep a small non‑VAT‑liable activity.

If you expect a longer period without activity, it is often more efficient to deregister from VAT and other obligations to avoid unnecessary reporting and potential penalties for late or missing returns.

Closing your sole proprietorship with the DBA

When you decide to stop your business permanently, you must formally close it with the Danish Business Authority. Closing a sole proprietorship involves several coordinated steps:

1. Log in to Virk.dk and select the option to close (deregister) your business.
2. Deregister from VAT, payroll tax, import/export and any other schemes linked to your CVR number.
3. Prepare final accounts up to the closing date, including inventory, outstanding receivables and payables.
4. Submit final VAT returns and pay any remaining VAT due, or claim refunds if applicable.
5. Report your final business income and deductions in your personal tax return (oplysningsskema) for the year of closure.

Once the closure is registered, your CVR number is marked as inactive in the CVR register. You must keep your accounting records for at least five years after closure, in line with Danish bookkeeping rules.

Consequences of not updating your details

Failing to report changes to the Danish Business Authority can have practical and financial consequences, such as:

• Official letters and digital messages sent to outdated addresses or contact details
• Incorrect VAT or tax registration, leading to wrong assessments and potential back payments
• Fines or fees for late deregistration from VAT or other schemes
• Problems with banks, suppliers or customers who rely on the CVR register for verification

Because most updates can be made quickly online, it is usually straightforward to stay compliant. Keeping your data current also strengthens your professional image and reduces the risk of administrative issues.

How an accounting firm can help you manage changes

Many sole proprietors prefer to let a professional accounting firm handle updates with the Danish Business Authority and SKAT. An accountant can:

• Assess which registrations you actually need and which can be removed
• Handle digital submissions on Virk.dk and ensure that all changes are consistent across systems
• Plan the timing of changes, such as VAT registration or closure, to minimise tax and cash‑flow impact
• Ensure that your bookkeeping, VAT returns and income tax reporting reflect the updated business structure

By coordinating legal registrations with day‑to‑day accounting, you reduce the risk of errors and free up time to focus on running and growing your business in Denmark.

Suspending or Closing a Sole Proprietorship with the DBA

At some point you may want to pause your activity or stop trading altogether. In Denmark, you handle this with the Danish Business Authority (Erhvervsstyrelsen) via Virk.dk. Understanding the difference between temporarily suspending and permanently closing your sole proprietorship helps you avoid unnecessary tax, VAT and reporting obligations.

Suspending a sole proprietorship (temporary inactivity)

You can make your business inactive if you plan to restart later. This is often relevant if you take a job, go on parental leave or test a different business idea.

In practice, “suspension” means you stop commercial activity but keep the CVR number. You must:

• Stop issuing invoices and stop all sales activities
• Settle outstanding VAT (moms) and submit a final VAT return for the last active period
• Close or adjust any payroll registrations if you no longer have employees
• Update your status on Virk.dk so the business is marked as inactive

You do this by logging in to Virk.dk with MitID and updating your business registration. If you are registered for VAT, you can request to be deregistered for VAT while remaining registered as a business. This is useful if your expected turnover will stay below the VAT registration threshold of 50,000 DKK over a 12‑month period.

Even when inactive, you may still have to file a tax return (årsopgørelse/udvidet selvangivelse) if you have any business-related income or expenses. If there is no activity at all, you typically report zero business income but still need to complete your personal tax return.

Closing a sole proprietorship (permanent cessation)

If you decide to stop your business permanently, you must formally deregister it. This is more than just stopping sales; you must close the business with the Danish Business Authority and, where relevant, with the Danish Tax Agency (Skattestyrelsen).

Key steps to close a sole proprietorship:

1. Stop all business activity
   End all sales, terminate contracts where possible and inform customers, suppliers and partners that you are closing.
2. Issue final invoices and collect receivables
   Send any remaining invoices and try to collect outstanding payments before you close. You must still declare this income in your final accounts.
3. Settle VAT (moms)
   If you are VAT registered, submit a final VAT return covering the period up to the closing date. This includes VAT on final sales and any VAT adjustments, for example on fixed assets if you have used the VAT deduction.
4. Handle employees, if any
   Terminate employment contracts in line with Danish employment law and any collective agreements. File final payroll reports (eIndkomst), settle holiday pay, ATP contributions and labour market contributions (AM-bidrag), and deregister as an employer on Virk.dk.
5. Deregister the business on Virk.dk
   Log in with MitID, find your business under “My businesses” and choose to deregister (luk virksomhed). You will be asked for a closing date and to confirm which registrations (VAT, employer, import/export etc.) should be terminated.
6. Prepare final accounts
   Prepare a final set of accounts from the start of the last financial year up to the closing date. This will be used for your personal tax return and to calculate any final tax and AM-bidrag.
7. Report final business income in your tax return
   Include your final profit or loss in your personal tax return. As a sole proprietor, business income is taxed as personal income, subject to AM-bidrag of 8% and then income tax at the applicable municipal, health and state rates. If your total personal income exceeds 588,900 DKK (after AM-bidrag), the top-bracket tax of 15% applies on the excess.

Deadlines and practical considerations

You should deregister the business as soon as you know you will stop trading. Waiting too long can create unnecessary VAT and reporting obligations. For VAT, you must file your final return by the normal deadline for your reporting frequency (monthly, quarterly or half-yearly). For tax, your final business income is reported in your annual tax return by the standard filing deadline for individuals.

If you miss deregistration or filing deadlines, you may receive estimated assessments and penalties from the tax authorities. Keeping your records up to date and closing the business promptly helps you avoid these issues.

Assets, inventory and private use when closing

When you close your sole proprietorship, you must consider how business assets and inventory are treated for tax and VAT purposes:

• If you transfer assets (for example a computer, car or equipment) from the business to private use, this may be treated as a sale at market value.
• If you were entitled to deduct VAT on these assets, you may have to account for output VAT on the deemed sale when closing.
• Remaining inventory at closing is normally treated as sold at market value and included in your taxable income; if you sell it at a lower price, you must be able to document this.

Correct valuation and documentation are important to avoid disputes with the tax authorities.

Record-keeping after suspension or closure

Even after you suspend or close your sole proprietorship, you must keep your accounting records, vouchers and tax documentation for at least 5 years, counted from the end of the financial year they relate to. This includes invoices, bank statements, contracts, payroll records and VAT documentation. Digital storage is acceptable as long as the material is complete, readable and accessible in Denmark.

When to seek professional help

Suspending or closing a sole proprietorship in Denmark is usually straightforward, but it can become complex if you have employees, large assets, significant inventory or outstanding debts. An accountant can help you:

• Plan the most tax-efficient closing date
• Handle final VAT and tax calculations
• Value assets and inventory correctly
• Ensure all registrations with the Danish Business Authority and the Tax Agency are properly terminated

Properly managing suspension or closure reduces the risk of unexpected tax bills, penalties and administrative problems, and allows you to move on to your next step with a clean slate.

Record-Keeping Requirements and Recommended Accounting Practices

Good record-keeping is not only a legal obligation for sole proprietors in Denmark, it is also essential for managing cash flow, planning taxes and avoiding problems with the Danish Business Authority (Erhvervsstyrelsen) and the Danish Tax Agency (Skattestyrelsen). As a sole proprietor, you are personally liable for your business, so your accounting must clearly show the financial position of your enterprise.

Legal record-keeping requirements for sole proprietors

Danish bookkeeping rules apply to almost all businesses, including small sole proprietorships. In practice, this means you must:

• Keep orderly and systematic records of all business transactions
• Be able to document every entry in your accounts with underlying vouchers (invoices, receipts, bank statements, contracts, etc.)
• Prepare accounts that make it possible to calculate your taxable income and VAT (moms), if applicable
• Store accounting material and documentation securely for at least 5 years from the end of the financial year

Records may be kept electronically or on paper, but they must be readable, accessible in Denmark and presented to authorities on request. If you use foreign cloud systems, you must ensure that data can be made available to Danish authorities without undue delay.

What you must keep as accounting documentation

As a minimum, a Danish sole proprietor should keep:

• Sales invoices and credit notes issued to customers
• Purchase invoices and receipts from suppliers
• Bank statements for all business accounts and payment cards
• Cash register reports or cash books, if you handle cash
• Contracts and agreements with customers, suppliers and collaborators
• Payroll documentation if you have employees (pay slips, holiday pay, pension, ATP, tax withholdings)
• Loan agreements and leasing contracts
• Fixed asset documentation (purchase invoices, depreciation schedules, sale documents)

Each transaction should be traceable from the original document to the accounting entry and vice versa. This “audit trail” is crucial if the tax authorities review your business.

Separation of business and personal finances

Even though a sole proprietorship is not a separate legal entity, you should always separate business and private finances. This makes bookkeeping easier and reduces the risk of errors.

• Use a dedicated business bank account and, ideally, a separate business payment card
• Avoid paying private expenses from the business account and vice versa
• If you do pay mixed expenses, document clearly which part is business-related

Clean separation of finances is also important if the tax authorities question deductions or if you apply for financing.

Core accounting records you should maintain

To comply with Danish rules and to have a clear overview of your business, it is recommended that you maintain at least the following records:

• A general ledger with all income and expense accounts
• A list of customers and outstanding receivables
• A list of suppliers and outstanding payables
• A cash book if you receive or pay cash
• A fixed asset register for equipment, vehicles and other long-term assets
• VAT (moms) accounts showing VAT on sales and VAT on purchases

Most of this can be handled efficiently in an online accounting system, which also helps you meet documentation and storage requirements.

Recommended accounting practices during the year

Regular routines reduce the risk of mistakes and missed deadlines. For a Danish sole proprietor, good practice includes:

• Recording income and expenses continuously, at least once a week
• Reconciling bank accounts monthly against your accounting records
• Checking that all sales invoices are paid and following up on overdue customers
• Reviewing expenses to ensure they are business-related and properly documented
• Updating your fixed asset register when you buy or sell equipment

By keeping your accounts up to date, you can estimate your expected tax and VAT liabilities during the year and avoid liquidity surprises.

VAT (moms) record-keeping and reporting

If your annual turnover exceeds the Danish VAT registration threshold, you must register for VAT and keep specific VAT records. You must:

• Issue VAT-compliant invoices with your CVR number, VAT rate and VAT amount
• Record VAT on sales (output VAT) and VAT on purchases (input VAT) separately
• Store all invoices and receipts that support your VAT returns

VAT must be reported digitally to Skattestyrelsen within the deadlines that apply to your reporting frequency. Incorrect or incomplete VAT records can lead to reassessments, interest and surcharges.

Digital tools and automation

Danish authorities strongly encourage digital bookkeeping. As a sole proprietor, you benefit from using:

• Online accounting software integrated with your bank for automatic import of transactions
• Digital invoice and receipt capture (for example, scanning apps) to reduce paper handling
• Electronic filing systems with clear folder structures for contracts, invoices and tax documents

Digital solutions make it easier to comply with the 5-year storage requirement and to provide documentation quickly in case of a control.

Year-end closing and financial overview

At the end of each income year, you should prepare a simple set of accounts, even if you are not required to file full financial statements with the Danish Business Authority. A typical year-end process includes:

• Ensuring all income and expenses for the year are recorded
• Reconciling bank accounts, loans and credit cards
• Updating depreciation on fixed assets
• Checking VAT accounts and other tax-related balances
• Preparing an income statement and a balance sheet

These accounts form the basis for your tax return and help you evaluate profitability, pricing and cost structure for the coming year.

Common mistakes and how to avoid them

Sole proprietors in Denmark often run into problems because of:

• Missing or incomplete documentation for expenses
• Mixing private and business transactions
• Irregular bookkeeping, leading to rushed and inaccurate year-end figures
• Incorrect VAT treatment of cross-border services and purchases
• No backup of digital records

These issues can usually be avoided by setting up clear routines from the start and, where necessary, getting professional help.

When to involve a professional accountant

While Danish law allows you to handle your own bookkeeping, many sole proprietors choose to work with a professional accountant or bookkeeper, especially when:

• Turnover increases and transactions become more complex
• You become VAT-registered or start trading internationally
• You hire employees and must handle payroll, holiday pay, ATP and pensions
• You want to optimise deductions and plan your tax situation

A professional can help you set up a compliant chart of accounts, implement efficient routines and ensure that your records meet the expectations of both the Danish Business Authority and the tax authorities.

Common Compliance Mistakes Sole Proprietors Make with the DBA

Many sole proprietors in Denmark handle their own registrations and reporting with the Danish Business Authority (Erhvervsstyrelsen / DBA). This is perfectly possible, but a number of recurring mistakes can lead to fines, late fees or unnecessary audits. Understanding these common pitfalls helps you keep your business compliant and avoid costly surprises.

1. Registering Too Late or with the Wrong Start Date

A frequent mistake is starting to trade before the business is properly registered, or choosing an incorrect start date on Virk.dk. In Denmark, you must register your sole proprietorship when you begin independent economic activity with a profit motive, not only when you issue your first invoice. If you backdate or postdate the start date without reflecting reality, it can create mismatches between your accounts, tax returns and DBA records.

Make sure that:

• Registration on Virk.dk is completed before or at the time you start business activities
• The start date matches your first binding business actions (e.g. contracts, invoices, purchases for business use)
• You update the start date only if you have a clear, documented reason and it reflects actual circumstances

2. Misunderstanding VAT (Moms) Registration Thresholds

Another common compliance error is incorrect or late VAT registration. In Denmark, you must register for VAT when your taxable turnover exceeds 50,000 DKK over a 12‑month period. Many sole proprietors either:

• Register for VAT too late, after clearly passing the 50,000 DKK threshold
• Register voluntarily for VAT but then fail to file VAT returns on time
• Incorrectly treat exempt activities as VAT‑liable, or vice versa

Late VAT registration can result in having to pay VAT retroactively on past sales, plus interest and potential surcharges. Monitor your turnover closely from day one and register for VAT as soon as it is clear that you will reach or exceed the 50,000 DKK threshold within 12 months.

3. Not Updating Business Information with the DBA

Many sole proprietors forget that changes must be reported to the DBA via Virk.dk. Typical omissions include:

• Change of business address or place of activity
• Change of main business activity (industry code / branchekode)
• Switching from part‑time to full‑time activity
• Adding or removing secondary activities

If the DBA’s register does not match your actual situation, it can cause issues with public authorities, banks, insurance companies and customers. It may also affect whether you are subject to specific industry rules or inspections. Always update your details promptly when something important changes.

4. Choosing the Wrong Industry Code (Branchekode)

When you register your sole proprietorship, you must select a NACE/DB07 industry code that best describes your main activity. A common mistake is choosing a code that is too broad, outdated or simply incorrect. This can lead to:

• Misclassification for statistics and sector‑specific rules
• Missing out on relevant support schemes or guidance
• Increased risk of questions from authorities if your accounts do not match the registered activity

Review the available industry codes carefully and select the one that reflects your primary source of revenue. If your business model changes, update the code accordingly via Virk.dk.

5. Ignoring Deadlines for Annual Reporting and VAT

Even though sole proprietorships do not file annual financial statements with the DBA in the same way as companies, many obligations are still time‑sensitive. Common mistakes include:

• Missing VAT filing and payment deadlines (monthly, quarterly or half‑yearly, depending on your allocation)
• Not aligning your bookkeeping with the income year used for tax purposes
• Forgetting to close VAT periods when you stop or suspend activity

Late VAT returns can trigger automatic penalties and interest. Use digital calendars, accounting software or professional assistance to ensure you never miss a deadline.

6. Mixing Personal and Business Finances

Because a sole proprietorship is not a separate legal entity, many owners mix private and business transactions in the same bank account and payment cards. While this is legally possible, it often leads to:

• Incomplete or inaccurate bookkeeping
• Difficulty documenting deductible expenses during audits
• Higher risk of errors in VAT and tax reporting

The DBA and tax authorities expect clear, traceable records. Using a dedicated business bank account and keeping systematic records of all income and expenses significantly reduces compliance risk.

7. Poor or Incomplete Bookkeeping

Insufficient bookkeeping is one of the most frequent reasons for problems with authorities. Typical issues include:

• Missing invoices or receipts for expenses
• No clear numbering or dating of invoices issued
• Not reconciling bank statements with accounting records
• Storing records in formats that are not accessible or readable over time

Danish rules require that accounting records are kept for at least 5 years. Even as a small sole proprietor, you should maintain structured, chronological records that clearly show your turnover, costs, VAT and balances. This is essential if the DBA or SKAT requests documentation.

8. Incorrect Handling of VAT on Cross‑Border Transactions

With more small businesses selling online, mistakes around EU and non‑EU transactions are increasingly common. Sole proprietors often:

• Charge Danish VAT on B2B sales to VAT‑registered customers in other EU countries when the reverse‑charge mechanism should apply
• Fail to apply Danish VAT on digital services to private customers in Denmark
• Ignore distance‑selling and special VAT schemes when selling to private customers in other EU countries

Incorrect VAT treatment can trigger corrections and penalties. If you trade across borders, make sure you understand when to charge Danish VAT, when to use reverse charge, and when special EU VAT rules apply.

9. Not Using or Mismanaging Digital Tools (MitID, e‑Boks, Virk.dk)

All communication with the DBA and most other authorities is digital. Common mistakes include:

• Not activating or regularly checking e‑Boks, and therefore missing important letters and deadlines
• Sharing MitID credentials with others instead of using proper authorisations
• Failing to update contact information, resulting in undelivered notifications

If you do not read messages in e‑Boks, you are still considered notified. This means you can incur fines or lose rights even if you “didn’t see the letter”. Log in regularly and keep your contact details up to date.

10. Forgetting to Suspend or Close the Business Properly

When a sole proprietor stops trading, a frequent mistake is to simply “go quiet” without formally notifying the DBA. If you do not deregister or suspend the business on Virk.dk:

• VAT obligations may continue, and you may still be expected to file returns
• Public registers will show the business as active, which can create confusion
• You may continue to receive letters and reminders from authorities

If you stop or pause your activity, update your status with the DBA and ensure that VAT and other registrations are closed or adjusted. This prevents unnecessary administrative burdens and potential penalties.

11. Underestimating the Link Between the DBA and SKAT

Many sole proprietors see the DBA and SKAT as completely separate, but data flows between authorities. Inconsistencies between what you register with the DBA and what you report to SKAT can trigger questions or audits. Examples include:

• Turnover levels that do not match your registered activity or VAT status
• Large changes in activity that are not reflected in your DBA registration
• Inactive businesses that still show significant income or VAT

Ensure that your registrations, bookkeeping and tax returns tell the same coherent story about your business.

12. Not Seeking Professional Help Early Enough

Many sole proprietors wait until they receive a warning or audit notice before contacting an accountant or bookkeeper. By that time, errors may have accumulated over several years, making corrections more complex and expensive.

Engaging professional accounting support early can help you:

• Register correctly with the DBA and for VAT from the start
• Set up proper bookkeeping routines and digital tools
• Meet all reporting deadlines and documentation requirements
• Handle changes in activity, cross‑border trade and growth in a compliant way

Preventing mistakes is almost always cheaper and less stressful than fixing them later. For many sole proprietors, using professional accounting services is an investment in stability, compliance and long‑term business growth.

Interaction Between the DBA and SKAT (Tax Agency)

The Danish Business Authority (Erhvervsstyrelsen, often abbreviated as DBA) and the Danish Tax Agency (Skattestyrelsen, commonly still called SKAT) work closely together in managing your sole proprietorship. Understanding how these two authorities interact helps you avoid missed registrations, incorrect tax reporting and unnecessary penalties.

Who Does What: DBA vs. SKAT

The DBA is primarily responsible for your business registration and legal status, while SKAT handles taxation and duties. In practice, this means:

• DBA: Registers your sole proprietorship in the Central Business Register (CVR), manages your company details, industry codes (branchekode/NACE), and certain licenses.
• SKAT: Manages your tax relationship, including income tax, VAT (moms), A-tax and AM-contribution if you have employees, and other duties.

Although they have different roles, their systems are integrated. Information you submit to the DBA is shared with SKAT and forms the basis for your tax obligations.

What Happens When You Register a Sole Proprietorship

When you register your sole proprietorship via Virk.dk, you are actually initiating processes with both the DBA and SKAT at the same time:

• Your business is given a CVR number by the DBA.
• Information about your expected turnover, business type and start date is automatically forwarded to SKAT.
• Based on this, SKAT creates or updates your tax profile as a self-employed person (selvstændig erhvervsdrivende).

If you indicate that you expect an annual turnover above the VAT threshold (currently DKK 300,000 in a 12‑month period), SKAT will register you for VAT from the start date you choose. If you indicate that you will have employees, SKAT will also register you as an employer.

Data Flow Between the Authorities

The interaction between the DBA and SKAT is largely automated. Key examples include:

• Business start: Start date, business form and industry code from the DBA are used by SKAT to determine when your tax obligations begin and which rules apply.
• Changes to your business: Updates you make with the DBA (such as address, industry code or business name) are shared with SKAT and can affect your tax treatment, VAT control and correspondence.
• Business closure: When you deregister your sole proprietorship with the DBA, SKAT is notified that business activities have stopped from a specific date, which affects VAT, employer registrations and your tax assessment.

This integration reduces double reporting, but it also means that incorrect or outdated information at the DBA can lead directly to problems with SKAT.

VAT (Moms) and SKAT Registration

VAT registration is a good example of how the two authorities interact:

• You apply for VAT registration through the DBA’s interface on Virk.dk.
• The DBA records that your CVR number is VAT‑liable from a specific date.
• SKAT then sets up your VAT account, determines your VAT reporting frequency (typically quarterly for small businesses) and makes the VAT reporting forms available in TastSelv Erhverv.

If your turnover later exceeds the VAT threshold after you initially registered as non‑VAT‑liable, you must update your status through Virk.dk. This change is again communicated to SKAT, which adjusts your VAT obligations and deadlines.

Income Tax and the Interaction with Your CVR

As a sole proprietor in Denmark, your business is not taxed separately. Instead, your business profit is taxed as your personal income. The DBA’s registration of your CVR number and business start date informs SKAT that you are self‑employed, which affects:

• Your preliminary income assessment (forskudsopgørelse), where you must enter expected business profit.
• Your annual tax return (årsopgørelse), where business income and expenses must be reported correctly.
• Whether you are covered by the business tax scheme (virksomhedsordningen) or the capital return scheme (kapitalafkastordningen), if you choose to use them.

SKAT uses the information from the DBA to identify you as a business owner and to match your reported income with your CVR‑related activities. If your reported income does not match the scale of your registered business, this can trigger questions or audits.

Employer Registration and Payroll Taxes

If you hire employees, the interaction between the DBA and SKAT becomes even more important:

• You register as an employer via Virk.dk under your CVR number.
• The DBA records your status as an employer and passes this on to SKAT.
• SKAT then expects regular reporting and payment of:
  • A‑tax (withholding tax on salaries)
  • AM‑bidrag (labour market contribution, 8% of salary)
  • Any relevant ATP contributions and other statutory employer contributions

Failure to deregister as an employer with the DBA when you stop having employees means SKAT may still expect payroll reports and payments, which can lead to reminders and potential fines.

Deadlines, Reminders and Digital Communication

Both the DBA and SKAT rely on digital communication via e‑Boks and your MitID. The contact details you provide to the DBA are used by SKAT to send:

• Reminders about VAT reporting deadlines
• Information about changes in tax rules relevant to your business type
• Notices about missing reports or discrepancies

Typical deadlines that SKAT expects you to meet, based on your registrations, include:

• VAT reporting: Often quarterly for small sole proprietors, with reporting and payment usually due one month and 10 days after the end of the period.
• Employer reporting: Monthly reporting of A‑tax and AM‑contribution, generally due by the 10th of the following month.
• Annual tax return: Submission of your personal tax return, including business income, within the standard national deadlines.

Because the systems are connected, missing a deadline that SKAT expects based on your DBA registration can quickly result in automatic reminders and, in some cases, fines.

Changing or Closing Your Business: Impact on SKAT

Whenever you change or close your sole proprietorship with the DBA, you should consider the tax consequences with SKAT:

• Change of activity or industry code: May affect your eligibility for certain deductions, VAT rules or sector‑specific schemes.
• Change of address: Ensures SKAT’s records are correct and that any physical correspondence reaches you if needed.
• Temporary suspension or closure: When you deregister your business or VAT with the DBA, SKAT will stop expecting ongoing VAT and employer reports from the deregistration date, but you still need to submit final returns and settle any outstanding liabilities.

Always align your updates: change or close your registrations on Virk.dk and then check in TastSelv that SKAT’s information and your expected obligations have been updated accordingly.

Typical Issues and How to Avoid Them

Because of the close interaction between the DBA and SKAT, small mistakes can have larger consequences. Common issues include:

• Registering the wrong start date, leading to VAT obligations earlier than expected.
• Forgetting to register for VAT when turnover exceeds DKK 300,000 in 12 months.
• Not updating employer status after the last employee leaves.
• Closing the business with the DBA but forgetting to submit final VAT and tax returns to SKAT.

To avoid these problems, always:

• Review your registrations on Virk.dk after any change.
• Log into TastSelv Erhverv to confirm that SKAT’s view of your business matches your actual situation.
• Seek professional accounting support if you are unsure how a change at the DBA level will affect your tax position.

For sole proprietors in Denmark, staying compliant means understanding that every registration, update or closure with the DBA has a direct tax consequence with SKAT. Keeping both sides aligned is essential for smooth operations and predictable tax outcomes.

Social Security, ATP and Pension Considerations for Sole Proprietors

When you run a sole proprietorship in Denmark, you are personally responsible for arranging your own social security, ATP and pension. Unlike employees, you do not have an employer to handle these contributions for you, so planning ahead is essential both for your current protection and your retirement.

Social security as a sole proprietor

Danish social security is mainly financed through general taxation. As a sole proprietor, you usually gain access to core welfare benefits (healthcare, education, certain social benefits) through the tax you pay on your business and other income. However, some schemes depend on your specific situation and whether you pay certain contributions.

Key points to be aware of:

• Health insurance and public services – You are covered by the public healthcare system as a resident and taxpayer in Denmark. There is no separate health insurance contribution for sole proprietors.
• Unemployment benefits (A-kasse) – You are not automatically covered. To be eligible for unemployment benefits, you must voluntarily join an unemployment insurance fund (A-kasse) that accepts self-employed members and pay monthly contributions. Coverage conditions, qualifying periods and benefit amounts depend on the specific A-kasse and your income history.
• Sickness and maternity benefits – As a self-employed person, you may be entitled to sickness and maternity benefits, but the rules differ from those for employees. In many cases, you must document your income and business activity, and you may need to take out voluntary insurance with Udbetaling Danmark to receive benefits from an earlier date during sickness or maternity leave.

Because coverage and conditions can vary, it is important to review the rules with your A-kasse and Udbetaling Danmark and to keep accurate records of your business income.

ATP (Labour Market Supplementary Pension) for the self-employed

ATP (Arbejdsmarkedets Tillægspension) is a statutory supplementary pension scheme that employees in Denmark are automatically enrolled in. For employees, contributions are shared between employer and employee and are based on hours worked. As a sole proprietor, you are not automatically covered by ATP through your business activity.

In most cases:

• You do not pay ATP contributions solely because you run a sole proprietorship.
• You may still accumulate ATP if you have or had employment alongside your business where ATP contributions were paid.
• If you hire employees, you must register as an employer and pay ATP contributions for them according to the applicable ATP rates per hour or per month, depending on their working hours.

Since ATP is only one part of the Danish pension system, sole proprietors usually need to build additional pension savings to maintain their standard of living in retirement.

Public pension and your future retirement income

All residents who meet the residence and age requirements are entitled to the Danish state pension (folkepension). Your entitlement depends primarily on how many years you have lived in Denmark between the ages of 15 and the state pension age, not on whether you are self-employed or employed.

The state pension consists of:

• a basic amount, which is the same for everyone who qualifies fully, and
• a pension supplement, which is income-tested and may be reduced if you have significant other income, including private pension payouts.

Because the state pension alone is often not enough to secure a comfortable retirement, sole proprietors are strongly encouraged to build private pension savings in addition to any ATP and previous employer pensions.

Private pension options for sole proprietors

As a sole proprietor, you can choose between several types of private pension schemes. The most common are:

• Rate pension (installment pension) – Payouts are made in installments over a fixed period, typically 10–30 years. Contributions are usually tax-deductible within an annual limit. For rate pensions, the tax-deductible contribution limit is typically in the range of several hundred thousand DKK per year; contributions above the limit are not deductible.
• Lifelong annuity (livrente) – Provides a pension paid out for the rest of your life. Contributions to lifelong annuities can generally be deducted without the same fixed annual cap that applies to rate pensions, making them attractive for higher incomes.
• Old-age savings (aldersopsparing) – Payouts are tax-free, but contributions are not tax-deductible. There is an annual contribution ceiling, which is lower for people below the state pension age and higher for those close to retirement.

All contributions to tax-deductible pensions reduce your taxable income, and the savings are taxed at the special pension yield tax (PAL-skat) on the investment return, which is lower than ordinary income tax. When the pension is paid out, it is generally taxed as personal income, except for old-age savings, which are paid out tax-free.

How much should you save for pension as a sole proprietor?

There is no single rule that fits everyone, but many advisors recommend that self-employed people aim to save at least 12–18% of their annual profit before tax into pension, especially if they do not have significant pension savings from previous employment.

When deciding how much to save, consider:

• Your current age and expected retirement age
• Your existing pension savings (including ATP and any employer pensions)
• Your expected business income and how stable it is
• Whether you plan to sell your business or assets as part of your retirement plan

Because pension contributions reduce your taxable income, it can be tax-efficient to increase contributions in years with high profits, as long as you stay within the relevant deduction limits.

Balancing social security, ATP and pension with your cash flow

New sole proprietors often focus on immediate cash needs and postpone pension planning. This can create a significant gap later. A practical approach is to:

1. Set up a standing monthly transfer to a pension scheme, even if the amount is modest at first.
2. Review your contributions annually when you prepare your financial statements and tax return.
3. Increase contributions in profitable years to take advantage of tax deductions.

At the same time, consider whether voluntary insurance for sickness and maternity, and membership of an A-kasse, fit your risk profile and budget. These elements, together with your pension savings, form the core of your personal social safety net as a sole proprietor.

Why professional advice is important

Danish rules on pension deductions, social benefits and interaction with your personal tax situation are complex and change over time. The optimal solution depends on your income level, family situation and long-term plans.

Working with a professional accountant or financial advisor can help you:

• Choose the right mix of rate pension, lifelong annuity and old-age savings
• Use tax deductions efficiently without exceeding annual limits
• Coordinate your pension planning with your business structure and any employment income
• Ensure that your social security coverage (A-kasse, sickness and maternity insurance) matches your needs

By actively managing social security, ATP and pension from the start, you protect both your current livelihood and your long-term financial security as a sole proprietor in Denmark.

Hiring Employees as a Sole Proprietor: Registration and Obligations

As your Danish sole proprietorship grows, you may reach a point where you need employees. Hiring staff in Denmark is highly regulated and closely linked to the Danish Business Authority (Erhvervsstyrelsen), the Danish Tax Agency (Skattestyrelsen) and several other public bodies. Understanding your registration duties and ongoing obligations is essential to avoid fines, back payments and compliance issues.

Registering as an employer (arbejdsgiver) with SKAT

Before you pay any salary, you must register as an employer with the Danish Tax Agency via TastSelv Erhverv on virk.dk. This registration links your sole proprietorship’s CVR number to an “employer” role and enables you to report payroll data through the eIncome (eIndkomst) system.

When you register, you will typically need to:

• Confirm your business details (CVR, address, contact information)
• Indicate that you will have employees and from which date
• Specify whether you will pay A-income (regular salary) and B-income
• Register for labour market contributions (AM-bidrag) and A-tax (A-skat) withholding

Once registered, you must report salary, withheld A-tax and AM-bidrag for each employee every time you pay wages, and no later than the 10th of the following month for most small employers. Late or missing reports can trigger penalties and interest.

Withholding A-tax and labour market contributions

As an employer in Denmark, you are responsible for withholding and paying:

• Labour market contribution (AM-bidrag) at 8% of the gross salary before A-tax
• A-tax (A-skat), which is the employee’s income tax based on their tax card (skattekort)

Each employee must provide a valid electronic tax card. You retrieve the tax card automatically through the eIncome system; you must not calculate tax based on assumptions. If you do not have a tax card for an employee, you must withhold tax at the highest rate (typically 55%) until a valid card is available.

You pay the withheld A-tax and AM-bidrag to SKAT monthly. For most small sole proprietors, the payment deadline is the 10th of the following month. You must reconcile your payroll records with the amounts reported in eIncome and the payments made to SKAT.

Registering for ATP and other mandatory schemes

Most employees in Denmark must be covered by the statutory labour market supplementary pension (ATP Livslang Pension). As an employer, you are responsible for registering with ATP and paying both the employer and employee contributions.

For full-time employees (37 hours per week), the ATP contribution is a fixed amount per month, where the employer pays the main share and the employee pays a smaller share that you withhold from salary. Part-time employees pay a reduced ATP contribution depending on their hours. Rates are adjusted periodically, so you must check the current ATP tables and ensure your payroll system uses the correct amounts.

In addition to ATP, you may also be required to register for:

• Industrial injury insurance (arbejdsskadeforsikring) for all employees
• Occupational pension schemes if required by a collective agreement you have signed
• Holiday pay schemes, for example via FerieKonto or an approved holiday fund

Holiday pay and working time rules

Danish employees are covered by the Holiday Act (Ferieloven). As an employer, you must accrue and pay holiday pay correctly:

• Employees earn 2.08 days of paid holiday for each month of employment, up to 25 days per holiday year
• Holiday is accrued and can be taken on an ongoing basis (samtidighedsferie)
• For hourly-paid employees, you typically pay 12.5% of the qualifying salary as holiday pay

You must report and pay holiday pay to FerieKonto or another approved scheme unless you are legally allowed to manage holiday pay yourself under a collective agreement. Failure to report or pay holiday pay correctly can lead to claims from employees and demands from the authorities.

You must also comply with working time rules, including limits on weekly working hours and mandatory rest periods. If your business operates with irregular hours, night work or weekend work, you should ensure your employment contracts and schedules respect Danish and EU working time regulations.

Employment contracts and minimum standards

When you hire staff, you must provide a written employment contract or employment information if the employment lasts more than a short period and exceeds a minimum number of weekly hours. The contract should clearly state:

• Employer and employee details
• Job title and job description
• Start date and, if relevant, end date
• Place of work
• Working hours and schedule
• Salary, bonuses, pension and other benefits
• Holiday rights and holiday pay arrangements
• Notice periods and termination conditions

Denmark does not have a single statutory minimum wage, but many sectors are covered by collective agreements (overenskomster) that set minimum pay, pension contributions, overtime rules and other conditions. Even if you are not formally part of a collective agreement, these standards often influence what is considered reasonable and lawful. Underpaying employees can lead to disputes, reputational damage and potential legal action.

Registering employees for social security and insurance

Employees in Denmark are generally covered by the public social security system through taxes and contributions. As an employer, your main duties are to:

• Ensure employees are registered with a CPR number and have the right to work in Denmark
• Withhold and pay AM-bidrag and A-tax correctly, which finance social security benefits
• Take out mandatory industrial injury insurance covering work-related accidents and occupational diseases

If you hire foreign employees or cross-border workers, additional registration and reporting obligations may apply, including reporting to the RUT register for posted workers or handling A1 certificates for social security. You should seek specialised advice in these cases.

Handling employees’ e-Boks and digital communication

Most official communication with employees about tax, social security and public benefits is sent to their personal e-Boks. As an employer, you must ensure that you submit correct and timely information to the authorities so that employees receive accurate statements and benefit calculations. You should also inform employees about how their salary, tax and holiday pay are reported, and where they can see this information online.

Data reporting and payroll systems

To stay compliant, you need a reliable payroll process that can handle:

• Monthly salary calculations, including overtime, allowances and deductions
• Automatic calculation of AM-bidrag, A-tax, ATP and other contributions
• Electronic reporting to eIncome, ATP, FerieKonto and other schemes
• Generation of payslips that meet Danish legal requirements

Many sole proprietors use professional payroll software or outsource payroll to an accountant or payroll bureau. This reduces the risk of errors and helps you keep up with changes in tax rates, thresholds and reporting rules.

Health and safety obligations

Once you have employees, you must comply with Danish health and safety legislation. This includes:

• Ensuring a safe and healthy working environment
• Conducting workplace risk assessments (APV – arbejdspladsvurdering)
• Providing necessary training, instructions and protective equipment
• Reporting work-related accidents and occupational diseases to the authorities and your insurance

Depending on the size and nature of your business, you may need a formal health and safety organisation or appointed safety representatives. Even as a small sole proprietor, you are fully responsible for your employees’ safety.

When to involve a professional accountant

Hiring employees significantly increases your administrative burden and compliance risk. A professional accountant or payroll specialist can help you:

• Register correctly as an employer and set up ATP, holiday pay and insurance schemes
• Implement a compliant payroll system and reporting routines
• Interpret collective agreements and sector-specific rules
• Prepare employment contracts and internal policies that reflect Danish law

By outsourcing payroll and compliance tasks, you can focus on running and growing your business while ensuring that your sole proprietorship meets all Danish employer obligations.

Insurance Requirements and Risk Management for Sole Proprietors in Denmark

Running a sole proprietorship in Denmark means you and your business are legally the same person. This makes smart insurance and risk management essential, because business problems can quickly become personal financial problems. While some insurances are legally required in specific situations, others are strongly recommended to protect your income, assets and long-term plans.

Why risk management matters for sole proprietors

As a sole proprietor, you have unlimited personal liability for your business obligations. If something goes wrong – an accident, a client claim, a tax mistake or a data breach – your private assets (such as savings or even your home) can be at risk. A basic risk management plan should therefore cover three areas:

• Legal and financial liability (claims from customers, suppliers or authorities)
• Operational risks (damage to equipment, IT systems, premises, stock)
• Personal income and health (illness, accidents, loss of earning capacity)

Legally required insurances in Denmark

Whether you must buy insurance depends mainly on whether you have employees and what type of work you do.

• Workers’ compensation insurance (arbejdsskadeforsikring) – Mandatory if you employ staff, including part-time and temporary workers. It covers work-related injuries and occupational diseases. You must take out this insurance from the first day an employee starts.
• Motor liability insurance – Mandatory for any business vehicle registered in Denmark. This covers damage you cause to others while driving. If you use your private car for business, you must ensure your policy allows business use; otherwise, claims can be rejected.
• Certain regulated professions – Some professions require specific liability insurance or guarantees (for example, certain construction trades, financial services or advisory roles). These requirements can follow from sector legislation or authorisations, not directly from the Danish Business Authority, so you must check the rules for your industry before starting work.

Core business insurances most sole proprietors should consider

Even when not legally required, several types of insurance are highly relevant for most sole proprietors in Denmark:

• Professional liability insurance (erhvervsansvar / rådgiveransvar) – Protects you if a client claims financial loss due to your advice, services or mistakes. This is crucial for consultants, IT specialists, designers, accountants, engineers and other knowledge-based businesses.
• General liability insurance – Covers personal injury and property damage you or your business cause to others during your activities, for example at a client’s premises or in your own office or workshop.
• Contents and equipment insurance – Covers computers, tools, inventory and other business assets against fire, theft, water damage and similar risks. If you run your business from home, you usually need a separate business policy; standard home insurance often excludes business equipment above a low limit.
• Cyber and data insurance – Becomes relevant if you store customer data, process payments or depend heavily on IT systems. It can cover costs related to data breaches, ransomware, system downtime and notification obligations under data protection rules.
• Legal expenses insurance – Helps cover lawyer and court costs in disputes with customers, suppliers, landlords or authorities. This can be included as an add-on to other business policies.

Protecting your income and personal security

Because you are personally responsible for your livelihood, insuring your ability to work is just as important as insuring your equipment.

• Loss of earning capacity insurance (erhvervsevnetabsforsikring) – Provides ongoing payments if illness or accident significantly reduces your ability to work. This can be structured to supplement public benefits and protect your long-term income.
• Health and accident insurance – Can give faster access to treatment and cover costs related to accidents, rehabilitation and temporary inability to work.
• Life and pension schemes – As a sole proprietor, you are not automatically covered by employer pension schemes. You should consider private pension contributions and, where relevant, disability and life insurance to protect dependants and your future income.

Risk management beyond insurance

Insurance is only one part of risk management. Many risks can be reduced or avoided through good planning and internal routines:

• Clear written contracts with customers and suppliers, including scope of work, limitations of liability and payment terms
• Strong bookkeeping routines and timely reporting to the Danish Tax Agency and other authorities
• Regular data backups, secure passwords and basic IT security measures
• Workplace safety procedures, especially if you work with machinery, chemicals or physical labour
• Separation of business and personal finances, including a dedicated business bank account

How to choose the right coverage level

When you speak with an insurance provider, be prepared to describe your business in detail: turnover, number of clients, type of services or products, whether you visit customers, store goods or handle sensitive data. This helps determine realistic coverage limits and deductibles.

As a rule of thumb, many small Danish service businesses choose professional and general liability coverage in the range of DKK 1–5 million per claim, depending on the potential damage a mistake could cause. If you handle large contracts or critical data, higher limits may be appropriate.

Working with an accountant on risk and compliance

A professional accountant can help you identify financial and compliance risks that insurance alone cannot solve. This includes:

• Ensuring your bookkeeping and VAT handling reduce the risk of audits and penalties
• Advising on the financial impact of different insurance options and deductibles
• Helping you assess when your risk profile has changed – for example, when turnover grows, you hire staff or enter new markets – so you can update your insurance and risk strategy in time

By combining appropriate insurance with solid accounting routines and clear contracts, you create a much more resilient sole proprietorship that can handle unexpected events without threatening your personal finances.

Using Professional Accounting Services to Stay Compliant with the DBA

Staying fully compliant with the Danish Business Authority (Erhvervsstyrelsen) and the Danish Tax Agency (Skattestyrelsen) can be challenging for sole proprietors. Rules on VAT, bookkeeping, annual reporting and digital communication change regularly, and mistakes can quickly lead to fines, interest or unnecessary tax payments. Professional accounting services help you navigate these obligations so you can focus on running and growing your business.

How an accountant helps you stay compliant with the DBA

A qualified accountant or bookkeeper can take over the ongoing tasks that are directly linked to DBA and tax compliance, including:

• Correct registration of your sole proprietorship in the Central Business Register (CVR) and updating changes (address, activities, ownership, employees)
• Assessment of whether you must register for VAT (moms) when your 12‑month turnover approaches DKK 50,000
• Correct setup of VAT schemes (e.g. quarterly or half‑yearly reporting, import/export rules, reverse charge)
• Ensuring your bookkeeping meets the Danish Bookkeeping Act, including digital storage and documentation requirements
• Preparing figures for your annual tax return (oplysningsskema) and business statement (udvidet selvangivelse for selvstændige)
• Coordinating information that must be consistent between the DBA, Skattestyrelsen and other authorities

Bookkeeping and record‑keeping that meet Danish standards

The Danish Bookkeeping Act requires that all businesses, including sole proprietorships, keep orderly and traceable records. In practice this means:

• Using a bookkeeping system that complies with Danish digital bookkeeping requirements when they apply to your business
• Storing vouchers and documentation (invoices, receipts, bank statements, contracts) securely for at least 5 years
• Being able to document each transaction from source document to financial statement and tax return
• Separating private and business transactions, typically via a dedicated business bank account

Professional accountants set up a structure that fulfils these rules, so that if the DBA or Skattestyrelsen requests documentation or performs a control, your records are complete and easy to present.

VAT (moms) and tax: avoiding penalties and overpayment

VAT and income tax are the areas where sole proprietors most often make mistakes. An accountant helps you:

• Monitor when your turnover exceeds the DKK 50,000 threshold so you can register for VAT on time
• Apply the correct VAT rate (25% standard rate) and identify VAT‑exempt activities where relevant
• Handle EU B2B and B2C transactions, reverse charge, and reporting of intra‑EU trade
• Prepare and submit VAT returns on time according to your reporting frequency
• Calculate your taxable profit correctly, including allowable business deductions, depreciation and use of your home for business

By ensuring accurate VAT and tax calculations, a professional can both reduce the risk of fines and help you avoid paying more tax than necessary within the legal framework.

Support with employees, ATP and social contributions

If you hire employees, your obligations increase significantly. You must register as an employer, withhold A‑tax and labour market contributions (AM‑bidrag), pay ATP contributions and comply with holiday and employment rules. An accountant can:

• Register your business correctly as an employer with the relevant authorities
• Set up payroll so that A‑tax, AM‑bidrag and ATP are calculated and reported correctly
• Ensure that holiday pay and other employee‑related obligations are handled in line with Danish law

This reduces the risk of errors that can lead to back payments, interest and penalties.

Digital tools: MitID, e‑Boks and Virk.dk

All communication with the DBA and many other authorities is digital. Professional accounting services are used to working with:

• MitID for secure login to public self‑service solutions
• e‑Boks, where official letters, deadlines and decisions are sent
• Virk.dk, where you register and update your business, submit reports and manage many obligations

An accountant can either guide you step by step or, with your authorisation, handle many of these digital tasks on your behalf to ensure that nothing is missed.

Choosing the right level of accounting support

Not every sole proprietor needs a full‑time accountant. You can choose a level of support that matches your situation:

• Basic bookkeeping and VAT – for small businesses that mainly need help with ongoing bookkeeping, VAT returns and simple year‑end adjustments
• Full accounting and reporting – for businesses with higher turnover, employees or more complex transactions that require regular reporting and analysis
• Ad‑hoc advisory – for those who handle daily bookkeeping themselves but want professional review and advice a few times a year

Many accounting firms offer fixed‑price packages tailored to sole proprietors, which makes it easier to budget for professional help.

Benefits beyond compliance

While the primary goal is to stay compliant with the DBA and tax rules, professional accounting services also provide strategic value:

• Better overview of cash flow and profitability through regular reports
• Support in choosing between taxation schemes for self‑employed (e.g. business scheme vs. personal income taxation) where relevant
• Guidance on investments, financing and growth plans based on reliable financial data

In many cases, the savings from optimised tax, fewer mistakes and better financial decisions exceed the cost of accounting services.

For sole proprietors in Denmark, working with a professional accountant is not just about outsourcing paperwork.
