Understanding the Tax Benefits for Research and Development Projects in Denmark for 2026

Overview of Tax Benefits for Research and Development in Denmark

Denmark offers a structured system of tax benefits to encourage companies to invest in research and development (R&D). These incentives are designed to reduce the effective cost of innovation, improve cash flow, and make it more attractive for both Danish and foreign businesses to locate their R&D activities in Denmark. Understanding how these rules work is essential for planning projects, budgeting, and making full use of the available reliefs.

For corporate income tax purposes, Denmark allows an immediate deduction of qualifying R&D expenses in the year they are incurred. This means that salaries, materials, external consultancy, testing, and other directly related R&D costs can generally be deducted at 100% from taxable income. In addition, companies may choose to capitalize and depreciate certain development costs, for example related to patents or acquired technology, when this is more beneficial from a long-term tax planning perspective.

A key feature of the Danish system is the possibility of a cash refund of tax losses linked to R&D activities. Companies can obtain a refund of 22% of the tax value of their R&D-related tax loss, up to a maximum loss of DKK 25 million per income year. In practice, this means that a company with qualifying R&D costs that create or increase a tax loss can receive a cash payment of up to DKK 5.5 million for that year. This mechanism is particularly important for start-ups and growth companies that invest heavily in development but do not yet generate taxable profits.

R&D tax benefits in Denmark apply across sectors and company sizes, as long as the activities meet the definition of research or development under Danish tax law. The rules are aligned with international standards, focusing on systematic, innovative work aimed at generating new knowledge, products, processes, or services, or significantly improving existing ones. Routine changes, cosmetic updates, and purely commercial activities do not qualify, which makes careful project scoping and documentation essential.

Denmark does not operate a separate, volume-based R&D tax credit with multiple rates, but instead integrates the incentive into the corporate tax system through enhanced deductibility and the refund of tax losses. This approach simplifies the calculation for many businesses, while still providing a substantial benefit. It also means that the value of the incentive is directly linked to the corporate tax rate, which is currently 22%.

In addition to the general tax rules, Danish companies can combine R&D tax benefits with other innovation-supporting instruments, such as grants, soft loans, and EU funding programmes, provided that the combined support does not exceed applicable state aid limits. Coordinating tax incentives with grant funding is important to avoid double financing of the same costs and to ensure that the overall structure remains compliant.

To benefit from the Danish R&D tax regime, companies must be able to identify and separate qualifying R&D costs from other operating expenses, maintain adequate project documentation, and reflect the deductions correctly in their tax returns. The tax authorities expect clear evidence of the innovative content, objectives, and progress of each project. Well-prepared documentation not only supports the claim but also reduces the risk of disputes and audits.

Overall, the Danish framework for R&D tax benefits is designed to be predictable and accessible, while still requiring a professional approach to classification and documentation. For businesses planning or already conducting R&D in Denmark, understanding these rules is a crucial first step to optimizing the total cost of innovation and ensuring that available tax advantages are fully utilized.

What Are the Key R&D Tax Incentives in Denmark for 2026?

Denmark offers a competitive package of tax incentives to encourage businesses to invest in research and development. For 2026, the framework continues to focus on making R&D spending more affordable through enhanced tax deductions, the option to convert tax losses into cash refunds, and favourable treatment of R&D-related payroll costs. Understanding how these incentives work can significantly reduce the effective cost of innovation projects carried out in Denmark.

The core incentive is the enhanced tax deduction for qualifying R&D expenses. Companies subject to Danish corporate income tax can deduct more than 100% of eligible R&D costs from their taxable income, up to a defined ceiling. This means that for every Danish krone spent on qualifying R&D, a higher amount can be deducted, lowering the company’s tax base and corporate tax bill. The enhancement applies to both internally performed R&D and certain outsourced activities, provided they meet the Danish definition of research and development and are directly connected to the company’s business.

Another key element is the possibility to obtain a cash refund of tax losses generated by R&D activities. If a company’s R&D deduction contributes to a tax loss in a given year, part of that loss can be converted into a payment from the Danish tax authorities instead of being carried forward. The refund is calculated by applying the standard corporate income tax rate to the eligible portion of the loss, up to an annual cap expressed in Danish kroner. This mechanism is particularly important for start-ups and growth companies that invest heavily in R&D but do not yet generate sufficient taxable profits to benefit from ordinary deductions.

Denmark also provides specific incentives related to R&D payroll. Salaries and related costs for employees who work directly on research and development projects can be included in the enhanced deduction base, as long as their activities qualify as R&D. This typically covers researchers, engineers, developers and technical staff, and may also include a proportionate share of management and support functions if they are demonstrably linked to eligible projects. Employer social security contributions and certain employee benefits connected to R&D work can also form part of the qualifying cost base.

In addition, companies can benefit from favourable treatment of R&D carried out in collaboration with universities, research institutions and other businesses. Payments for contract research, joint development projects and access to research infrastructure may qualify for the same enhanced deduction as in-house R&D, provided the company retains sufficient risk and ownership in the project outcomes. This encourages businesses to participate in innovation ecosystems and cross-sector partnerships without losing access to tax benefits.

For groups operating across borders, Denmark’s R&D incentives interact with the general corporate tax rules on transfer pricing and cost sharing. R&D costs allocated to a Danish entity under a cost-sharing arrangement or intra-group service agreement can qualify for the enhanced deduction if the Danish company bears the economic risk and expects to benefit from the results. Proper documentation of the allocation keys, contractual terms and project scope is essential to secure the incentive and withstand scrutiny from the tax authorities.

Finally, Denmark complements its R&D tax incentives with a stable corporate tax environment and clear administrative procedures. Claims for enhanced deductions and R&D loss refunds are generally made through the annual corporate tax return, supported by project descriptions, cost breakdowns and internal documentation. While there is no separate R&D tax credit application form, the tax authorities may request additional information or conduct reviews, so maintaining robust records of R&D activities, budgets and outcomes is a practical necessity for any company seeking to benefit fully from the available incentives in 2026.

Who Is Eligible for R&D Tax Relief in Denmark?

R&D tax relief in Denmark is designed to support a wide range of businesses that invest in developing new or improved products, services, technologies and processes. Eligibility does not depend on the size of the company, but on the nature of the activities and the way costs are incurred and documented. Both Danish and foreign-owned companies operating in Denmark can benefit, provided they are subject to Danish corporate taxation and meet the statutory criteria for research and development.

In practice, most eligible claimants fall into three main groups: Danish limited liability companies (ApS and A/S), branches of foreign companies that are taxable in Denmark, and certain partnerships where the partners are taxed in Denmark. Sole proprietors and smaller entities may also qualify, as long as they carry out genuine R&D activities and keep adequate accounting records that clearly separate R&D costs from other business expenses.

To qualify, a business must be engaged in systematic work aimed at achieving scientific or technological advancement, or at resolving scientific or technological uncertainty. Routine improvements, standard software implementation, or purely commercial activities such as marketing, sales or market research do not meet the Danish definition of R&D for tax purposes. The project must involve a clear element of innovation or technical challenge that could not be solved using readily available knowledge or standard solutions.

Eligible companies can benefit from enhanced tax deductions on approved R&D costs. Denmark allows an uplift on qualifying R&D expenses, meaning that a company can deduct more than 100% of these costs from its taxable income, up to a statutory cap expressed as a percentage of the total eligible expenditure. The exact uplift rate and maximum limit are set in the Danish tax legislation and apply equally to start-ups, SMEs and large enterprises, as long as the underlying activities meet the R&D criteria.

In addition to enhanced deductions, loss-making companies that carry out qualifying R&D may be able to convert part of their tax loss into a cash payment from the Danish tax authorities. This mechanism is particularly relevant for start-ups and early-stage technology companies that invest heavily in development but do not yet generate taxable profits. To be eligible, the company must have negative taxable income after including the R&D uplift, and the refundable amount is subject to an annual ceiling per income year.

Another important eligibility aspect concerns the types of costs that can be included in an R&D tax relief claim. Typically, the scheme covers salaries and wages for employees directly involved in R&D projects, employer social security contributions linked to those employees, materials and consumables used in experiments and testing, depreciation of equipment and machinery used for R&D, and certain external services such as consultancy, laboratory testing or specialized engineering support. Overheads and general administrative costs are only eligible to the extent that they can be clearly and reasonably allocated to R&D activities.

Companies engaged in collaborative or contract-based R&D must pay particular attention to who bears the technical and financial risk of the project. As a rule, the entity that owns the results and assumes the main R&D risk is the one that can claim the tax relief. If a Danish company performs R&D as a service for a related or unrelated party and is fully reimbursed for its costs plus a margin, it may have limited or no entitlement to R&D tax relief on those activities, because it does not carry the underlying risk or own the intellectual property.

There is no requirement that an R&D project be successful to qualify. Projects that are discontinued, fail to achieve their objectives, or result in partial solutions can still be eligible, provided that the work was planned, systematic and aimed at overcoming scientific or technological uncertainty. However, the company must be able to document the project’s objectives, methodology, milestones and technical challenges in case of a review by the Danish tax authorities.

To remain eligible, businesses must also comply with Danish bookkeeping and tax filing rules. This includes maintaining detailed records of R&D projects, time registration for staff working on R&D, invoices and contracts for external services, and clear internal guidelines for classifying costs as R&D. Claims must be made in the corporate tax return for the relevant income year, and late or incomplete filings can lead to a reduction or denial of the tax benefit.

In summary, any company that is taxable in Denmark, invests in genuine research and development, and can document its activities and costs in line with Danish tax rules may be eligible for R&D tax relief. This applies across sectors, from manufacturing, life sciences and clean tech to software, fintech and creative industries, as long as the projects involve real technological or scientific advancement rather than routine or purely commercial work.

Defining Research and Development: What Counts for Tax Relief?

Before you can claim any tax relief for research and development in Denmark, you need to be sure that your activities actually qualify as R&D under Danish tax law. The definition is narrower than “innovation” in a general business sense. Not every improvement, digitalisation project or product update will meet the criteria. Understanding where the line is drawn is essential to avoid rejected claims and potential audits.

Core criteria for R&D activities

For Danish tax purposes, R&D activities typically need to meet all of the following conditions:

• They aim to create new knowledge or use existing knowledge in a new way. The project should seek to develop new products, services, processes or technologies, or significantly improve existing ones.
• They involve a systematic and planned project. There should be a defined objective, timeline, budget and methodology, not just ad hoc problem-solving in day-to-day operations.
• They address scientific or technological uncertainty. At the outset, it should not be obvious how to achieve the desired result, or whether it is achievable at all, based on publicly available knowledge and standard industry practice.
• They rely on qualified expertise. The work is typically carried out by employees or external specialists with technical, scientific or professional qualifications relevant to the project.

Routine work, standard software implementation, or simple adaptation of existing solutions without overcoming real technical or scientific challenges will usually not qualify as R&D for tax relief purposes.

Typical qualifying R&D activities

While each project must be assessed individually, the following types of work often qualify for R&D tax relief in Denmark when they meet the criteria above:

• Experimental and theoretical work aimed at gaining new knowledge in natural sciences, engineering, IT, life sciences or similar fields.
• Applied research that translates existing scientific or technical knowledge into new or significantly improved products, materials, devices or processes.
• Development activities such as:
  • Design, construction and testing of prototypes or pilot plants
  • Development of new algorithms, data models or software architectures
  • Development of new production methods or automation solutions
  • Clinical or field testing required to verify performance or safety of new solutions
• Experimental development in digital projects, for example:
  • Creating new software platforms or core systems with non-trivial technical challenges
  • Developing new methods for data processing, AI/ML models or cybersecurity solutions
  • Building new integration frameworks or architectures that go beyond standard configurations

In all cases, the key is that the project goes beyond standard practice in your industry and that the outcome could not be reliably predicted at the start of the work.

Activities that usually do not qualify

Many business projects are innovative from a commercial perspective but do not meet the technical or scientific threshold required for R&D tax relief. The following activities are commonly excluded:

• Routine product updates, bug fixing and maintenance without substantial new functionality
• Graphic design, UI/UX improvements and branding work without underlying technical innovation
• Standard implementation or configuration of off‑the‑shelf software (ERP, CRM, CMS) using existing tools and methods
• Market research, customer surveys, pricing analysis and business model development
• Quality control and testing that simply verifies that products meet existing specifications
• Legal, administrative and financial activities related to the project
• Training, user documentation and support services

These activities may be important for your business, but they are generally treated as normal operating costs rather than R&D for tax purposes.

What types of costs can be linked to qualifying R&D?

Once you have identified which activities qualify as R&D, the next step is to determine which costs can be included in your tax relief calculation. In Denmark, the following categories are typically relevant when they are directly connected to eligible R&D projects:

• Employee costs for staff directly involved in R&D:
  • Salaries, holiday pay and bonuses linked to R&D work
  • Employer social security contributions and mandatory pension contributions
  • Proportionate costs for employees who split their time between R&D and non‑R&D tasks, based on documented time allocation
• External services from consultants, laboratories, testing facilities and research institutions, when their work forms an integral part of your R&D project.
• Materials and consumables used in experiments, prototypes and testing, including components, raw materials and laboratory supplies.
• Depreciation of R&D equipment such as laboratory equipment, testing rigs, servers or specialised machinery, to the extent they are used in R&D activities.
• Licences and software tools that are necessary for carrying out the R&D work, for example development environments, simulation tools or specialised analysis software.

General overheads such as rent, utilities and administrative salaries are usually not fully eligible but may be partially included if you can demonstrate a clear and reasonable allocation to R&D activities.

How to demonstrate that your work qualifies

To support your R&D tax relief claim, it is important to document why your activities meet the Danish definition of R&D. In practice, this means:

• Describing the technical or scientific uncertainties you faced at the start of the project
• Explaining why the solution was not obvious based on existing knowledge and standard practice
• Outlining your project plan, milestones and the methods used to test and validate results
• Keeping records of experiments, prototypes, test results and key technical decisions
• Maintaining time records that show how much effort employees spent on qualifying R&D tasks

A clear, structured description of your projects and costs makes it easier to show that your work falls within the scope of R&D as recognised by the Danish tax authorities and increases the likelihood that your tax relief will be accepted without adjustments.

The Role of SkatteFUNN in Denmark's R&D Tax Incentives

In Denmark, research and development is primarily supported through the general R&D tax deduction and the option to receive a cash refund of tax losses related to R&D costs. Unlike some other Nordic countries, Denmark does not operate a scheme called “SkatteFUNN” – that name refers to the Norwegian R&D tax incentive system. However, many international businesses and foreign owners use “SkatteFUNN” as a generic term for R&D tax support in Scandinavia. When planning projects and budgets, it is therefore important to understand how the Danish rules differ from the Norwegian SkatteFUNN model, and what this means for your company’s tax position.

The Danish regime is embedded in the ordinary corporate tax system rather than being a separate grant or subsidy. Companies that are tax resident in Denmark, as well as Danish permanent establishments of foreign companies, can deduct qualifying R&D expenses from their taxable income and, under specific conditions, receive a cash refund of tax losses linked to R&D costs. This is often functionally similar to what many businesses expect from a “SkatteFUNN-type” scheme, but the legal basis, calculation method and application process are different.

Under current Danish rules, qualifying R&D expenses can generally be deducted at up to 108% of the actual cost, subject to annual legislative adjustments. This enhanced deduction applies to costs that are directly connected to systematic research or development activities aimed at acquiring new knowledge or developing new or significantly improved products, services or processes. In addition, if your company is in a tax loss position, you may apply for a cash refund of the tax value of R&D-related losses, up to a capped amount per income year. The refund is calculated using the standard Danish corporate income tax rate of 22%, which effectively turns part of your R&D costs into an immediate cash benefit instead of a deduction carried forward.

Where the Norwegian SkatteFUNN scheme is project-based and requires a formal pre-approval of each project, the Danish system focuses on the nature of the activities and the documentation you keep in your accounting and project records. There is no separate “SkatteFUNN application” in Denmark. Instead, you claim the R&D deduction and any cash refund through your annual corporate tax return and accompanying schedules. The Danish Tax Agency may then review your claim and request additional documentation to verify that the activities qualify as R&D under Danish tax law.

For international groups that already use SkatteFUNN in Norway, one practical implication is that you cannot simply copy Norwegian project approvals or budgets and expect them to be accepted in Denmark. You need to map each project to the Danish definition of R&D, identify which costs are eligible under Danish rules, and ensure that time sheets, contracts, invoices and technical descriptions are prepared in a way that supports a Danish tax claim. This alignment is particularly important for shared R&D centres, cross-border development teams and group-wide innovation programs.

Another key difference from SkatteFUNN is that Denmark does not apply a fixed percentage credit on approved project costs. Instead, the benefit arises from the combination of the enhanced deduction and the 22% corporate tax rate, plus the possibility of a cash refund for tax losses. This means that the effective support level for your company will depend on your profitability, your overall tax position and how consistently you classify and document R&D expenses in your accounts.

Although Denmark does not have a scheme formally called SkatteFUNN, the Danish R&D tax rules can provide a comparable or, in some cases, higher level of support for innovative businesses, especially start-ups and scale-ups that invest heavily in development before generating taxable profits. To make the most of these incentives, companies should treat the Danish system as a distinct framework: understand the local legal definitions, integrate R&D tracking into their bookkeeping and project management, and plan their tax position over several years rather than focusing only on a single project approval.

For businesses operating across the Nordic region, a clear understanding of how the Danish R&D tax regime works – and how it differs from the Norwegian SkatteFUNN model – is essential for accurate budgeting, realistic cash flow forecasts and compliant tax reporting. Properly managed, the Danish incentives can significantly reduce the net cost of R&D and support a long-term innovation strategy tailored to the Danish market and tax environment.

Step-by-Step Guide to Applying for R&D Tax Relief

Applying for R&D tax relief in Denmark is a structured process that starts long before you submit anything to the Danish Tax Agency (Skattestyrelsen). A well-prepared application is based on clear project definitions, robust documentation and accurate cost calculations. Below is a practical, step-by-step guide that you can adapt to the size and complexity of your business.

1. Confirm that your activities qualify as R&D

Begin by identifying which of your projects meet the Danish definition of research and development. The work must aim to create new knowledge, products, services or processes, or significantly improve existing ones, and it must involve technical or scientific uncertainty that cannot be resolved using standard, easily available solutions.

At this stage, separate routine activities from genuine R&D. Routine software updates, cosmetic design changes or standard quality control usually do not qualify, while experimental development, prototype creation, testing of new technologies and feasibility studies often do.

2. Define the R&D projects and work packages

Next, group your qualifying activities into clearly defined R&D projects. For each project, prepare a short description that covers:

• Business objective and expected outcome
• Technical or scientific challenges you are trying to solve
• Innovative aspects compared with existing solutions
• Main phases or work packages (for example: research, design, prototyping, testing, validation)
• Planned timeline and key milestones

Clear project definitions make it easier to link costs to specific R&D work and to justify your claim in case of questions from Skattestyrelsen.

3. Map and classify eligible R&D costs

Once the projects are defined, identify all costs directly related to these activities. Typical categories include:

• Salaries and social contributions for employees directly involved in R&D
• Costs of external consultants and specialists working on the R&D project
• Materials and components used in experiments, prototypes and testing
• Depreciation or leasing costs of equipment and software used for R&D
• Costs of testing, trials and certification directly linked to the R&D work

Allocate each cost to a specific project and period. Exclude general overheads and commercial activities such as marketing, sales or routine production, unless a clearly identifiable portion is directly attributable to R&D.

4. Set up internal tracking and documentation

Before you submit any claim, ensure that your internal systems can support it. This usually means:

• Time registration for employees, showing hours spent on each R&D project
• Project codes in your accounting system to separate R&D costs from non-R&D costs
• Documented approval flows for R&D budgets and expenditures

Consistent tracking not only simplifies the calculation of your tax relief but also reduces the risk of disputes or adjustments during a tax audit.

5. Prepare the technical project description

Skattestyrelsen expects a clear explanation of why your projects qualify as R&D. Prepare a concise technical description for each project, including:

• The starting point: existing solutions or technologies you are building on
• The knowledge gap or uncertainty you are addressing
• The methods, experiments and tests you are using to resolve the uncertainty
• Interim and final results, including both successes and failures

Use language that is understandable to non-specialists, but keep enough technical detail to demonstrate the innovative and experimental nature of the work.

6. Calculate the R&D tax relief

Based on your mapped costs and time registrations, calculate the total eligible R&D expenditure for the financial year. Then apply the relevant Danish R&D tax rules in force, taking into account:

• Whether you are claiming an enhanced deduction, a tax credit, or both
• Any applicable percentage uplift on qualifying costs
• Limits or caps on cash refunds for companies in a tax loss position

Document the calculation logic in a simple worksheet or memo so that it can be easily followed by internal stakeholders and, if necessary, by the tax authorities.

7. Align the claim with your annual tax return

R&D tax relief is usually claimed through your corporate tax return. Coordinate early with your finance and accounting team so that:

• R&D costs are correctly reflected in the financial statements
• The tax return includes the correct figures and codes for R&D relief
• Any requested cash refund or credit is clearly indicated

Make sure that the numbers in your tax return match the supporting schedules and project documentation you have prepared.

8. Submit the application and supporting information

When your calculations and documentation are ready, submit your R&D tax relief claim together with your corporate tax return via the relevant digital platform provided by Skattestyrelsen. Keep copies of all submitted documents, including:

• Project descriptions and technical documentation
• Cost breakdowns and time registration reports
• Internal approvals and board or management minutes, if relevant

In some cases, Skattestyrelsen may request additional information or clarification. Respond promptly and provide clear, structured answers supported by your existing documentation.

9. Monitor the status and handle follow-up questions

After submission, monitor the status of your claim through the tax authority’s online systems and your company’s correspondence channels. If Skattestyrelsen asks for further details, focus on:

• Clarifying the innovative and experimental aspects of the projects
• Explaining how costs were allocated and why they are directly related to R&D
• Providing additional technical reports, test results or internal memos, if needed

Well-organised documentation usually allows you to respond quickly and reduce the risk of delays or adjustments.

10. Review, improve and plan future claims

Once your R&D tax relief has been processed, review the outcome and the internal process. Identify areas where you can improve for the next year, such as:

• Earlier identification of R&D projects and costs
• More precise time tracking and project coding
• Better coordination between technical teams and finance

By treating R&D tax relief as a recurring, structured process rather than a one-off exercise, your business can consistently maximise available benefits while staying fully compliant with Danish tax regulations.

Documentation Required for R&D Tax Relief Applications

Accurate and complete documentation is essential for securing research and development tax relief in Denmark. The Danish Tax Agency (Skattestyrelsen) expects businesses to demonstrate, with clear evidence, that their projects qualify as R&D and that the related costs have been correctly identified, measured and reported. Good documentation not only increases the chances of a successful claim, but also reduces the risk of adjustments, penalties or audits.

Core project documentation

Every R&D tax relief application should be built around solid project documentation. At a minimum, you should be able to present:

• Project descriptions – a concise explanation of each R&D project, including objectives, background, and the scientific or technological uncertainty you are trying to resolve.
• Technical documentation – design documents, specifications, architecture diagrams, test protocols, lab notebooks, code repositories, prototypes and pilot studies that show how the project advances knowledge or capability.
• Project plans and timelines – Gantt charts, sprint backlogs, milestone plans or similar documents that demonstrate the structured and systematic nature of the R&D work.
• Results and evaluation – test reports, validation results, performance comparisons, failure analyses and internal evaluation reports that document the outcome of the work, including unsuccessful attempts.

This documentation should clearly distinguish R&D activities from routine production, maintenance, bug fixing or purely commercial tasks.

Evidence of R&D activities and personnel

Because a significant portion of eligible R&D costs in Denmark relates to salaries and external services, you need robust evidence of who worked on what, and when. Typical documentation includes:

• Employment contracts and role descriptions for employees involved in R&D, showing their responsibilities and job functions.
• Time registration records (timesheets, digital time tracking, project codes in ERP systems) that allocate working hours to specific R&D projects and tasks.
• Organisational charts and internal responsibility matrices that clarify which teams and individuals are responsible for R&D.
• Consultancy and subcontractor agreements that describe the R&D nature of the services provided, including deliverables and milestones.

Time records should be consistent, traceable and prepared on an ongoing basis, not reconstructed retrospectively. Inconsistent or incomplete time tracking is one of the most common reasons for reductions in R&D tax claims.

Financial documentation of R&D costs

To calculate and substantiate the R&D tax relief, you must be able to reconcile your claim with your accounting records and tax return. The following documents are typically required:

• General ledger and trial balance with clearly identifiable R&D cost accounts or project codes.
• Payroll records for employees engaged in R&D, including gross salaries, pension contributions, social security contributions and other taxable benefits.
• Supplier invoices and contracts for R&D-related purchases, such as laboratory equipment, testing services, software licences used for development, and fees paid to research institutions.
• Capital expenditure documentation for assets used in R&D, including purchase invoices, depreciation schedules and internal allocation keys showing the R&D usage share.
• Internal cost allocation policies that explain how overheads, shared resources and common infrastructure are allocated to R&D projects.

All amounts included in the R&D tax relief calculation must be traceable back to your bookkeeping and, ultimately, to your annual financial statements and corporate tax return.

Project eligibility and classification documents

To demonstrate that your activities meet the Danish definition of R&D, it is helpful to prepare specific documents that link your projects to the legal criteria. These may include:

• Eligibility assessments where you explicitly describe the scientific or technological uncertainty, the innovative element and the systematic approach of each project.
• Internal approval documents (board minutes, R&D committee decisions, investment proposals) that show why the project was initiated and how it fits into your innovation strategy.
• Collaboration agreements with universities, GTS institutes or other research partners, including IP arrangements and division of tasks.
• Grant or funding applications submitted to Danish or EU programmes, which often contain detailed technical descriptions that can support your tax position.

These documents help the tax authorities understand why your work goes beyond routine development and qualifies as R&D for tax purposes.

Tax and filing documentation

In addition to project and cost evidence, you must keep all documents related to the tax filing itself. This typically includes:

• Completed R&D tax relief forms and any accompanying schedules submitted with your Danish corporate tax return.
• Internal calculation files (spreadsheets or system reports) showing how you derived the R&D base, applied relevant rates and arrived at the final tax credit or deduction.
• Correspondence with Skattestyrelsen, including questions, clarifications, preliminary assessments and final decisions.
• Board or management approvals of the R&D tax claim, where applicable.

Maintaining a complete audit trail from the underlying project data to the figures reported in the tax return is crucial for defending your claim in case of review.

Retention periods and format

Danish tax rules require businesses to retain accounting and tax documentation for a minimum of five years from the end of the financial year to which the documents relate. This retention requirement also applies to all R&D-related documentation. You may store documents electronically, provided that:

• They are legible and can be reproduced on request.
• The integrity and authenticity of the data are ensured.
• The structure of the data allows Skattestyrelsen to trace individual transactions and allocations.

For complex R&D portfolios, it is advisable to maintain a central digital archive or documentation package for each project, combining technical, financial and tax-relevant information.

Practical recommendations for stronger documentation

To make your R&D tax relief application more robust and easier to manage, consider the following practices:

• Define clear internal criteria for what your business considers R&D and align them with Danish tax rules.
• Assign unique project IDs and use them consistently in time tracking, accounting and technical documentation.
• Update project descriptions and eligibility assessments at key milestones rather than only at year-end.
• Ensure that finance, tax, and technical teams collaborate when preparing the documentation, so that technical narratives and cost figures are fully aligned.

Well-structured documentation not only supports your current R&D tax relief claims in Denmark, but also creates a solid foundation for future projects and potential changes in the tax framework.

How to Calculate R&D Tax Credit Amounts for Your Business

Calculating the value of R&D tax benefits for your business in Denmark starts with understanding which costs qualify and how they are treated for tax purposes. Danish rules distinguish between immediate deduction of R&D expenses, enhanced deduction for certain development costs and, for loss-making companies, the option to receive a cash payment of part of the tax value of the loss. Below is a practical, step-by-step approach you can use as a framework when planning your R&D projects and budgets.

1. Identify which projects qualify as R&D

Begin by listing all projects that involve systematic work to create new knowledge, products, processes or services, or to significantly improve existing ones. To be treated as R&D for tax purposes, a project should:

• Be based on a clear technical or scientific uncertainty at the outset
• Follow a structured plan, with defined objectives, milestones and documentation
• Be aimed at generating new or improved solutions, not just routine maintenance or minor upgrades

Only costs directly linked to these qualifying projects can be included in your R&D tax calculation.

2. Determine which costs can be included

Once you have identified your qualifying projects, you need to determine which expenses are eligible. In Denmark, the following cost categories typically form the basis for R&D tax calculations, provided they are directly attributable to the R&D activity:

• Salaries and social contributions for employees working on R&D, including a reasonable share of management and project coordination time
• Costs of materials, components, prototypes and consumables used in experiments, testing and development
• Depreciation of equipment and machinery used for R&D, based on the proportion of R&D use
• External services such as consultants, engineers, laboratories and testing facilities
• Software licences and cloud services used specifically for R&D activities
• Overheads that can be clearly allocated to R&D projects, such as a proportional share of rent, utilities and insurance

Keep a clear allocation key for shared costs (for example, percentage of floor space or hours of use) so that your calculation can be supported during a tax review.

3. Separate research and development from other activities

For many companies, employees and assets are used both for R&D and for commercial or administrative work. To calculate your R&D tax benefit accurately, you must separate the R&D portion from other activities. Typical methods include:

• Time sheets for employees, showing hours spent on specific R&D projects
• Project codes in your accounting system, so that R&D invoices and purchases are booked separately
• Usage logs for equipment and software, indicating the share of R&D use

The more precise your allocation, the more robust your R&D cost base will be.

4. Calculate your total qualifying R&D expenditure

After identifying and allocating all eligible costs, sum them to arrive at your total qualifying R&D expenditure for the income year. For example:

• R&D salaries (including social contributions): DKK 2,000,000
• Materials and prototypes: DKK 400,000
• Depreciation on R&D equipment: DKK 150,000
• External consultants and testing: DKK 250,000
• Allocated overheads: DKK 200,000

In this example, your total qualifying R&D expenditure would be DKK 3,000,000.

5. Apply the Danish corporate tax rate to see the tax value

Denmark applies a flat corporate income tax rate of 22%. Qualifying R&D expenses are generally deductible from your taxable income. This means that, in simple terms, every DKK 1 of deductible R&D cost reduces your tax bill by 22 øre, provided you have sufficient taxable profit.

Using the example above with DKK 3,000,000 of qualifying R&D expenditure and assuming you have taxable profit before R&D of at least that amount, the tax value is:

DKK 3,000,000 × 22% = DKK 660,000

This is the reduction in corporate tax you achieve by deducting your R&D costs.

6. Consider the treatment of development costs

Some development costs related to intangible assets, such as software or patents, can be capitalised and depreciated over time. Danish rules allow you to choose between immediate deduction of certain development costs or capitalisation and subsequent amortisation. The choice affects the timing of your tax benefit:

• Immediate deduction: you deduct the full amount in the year the cost is incurred, maximising the short-term tax benefit
• Capitalisation: you spread the deduction over several years through tax depreciation, which may better match the economic life of the asset

To calculate the impact, project your expected profits and compare the present value of the tax savings under each option.

7. Calculate the benefit if your company is loss-making

If your R&D expenses contribute to a tax loss, Danish rules allow certain companies to receive a cash payment of part of the tax value of the loss. The mechanism and limits are defined in tax legislation and are subject to specific conditions, including a cap on the amount of loss that can be converted to cash in a given year.

To estimate the benefit in a loss situation:

1. Calculate your tax loss after including R&D deductions
2. Determine the portion of the loss that can be converted to a cash payment, up to the statutory limit
3. Multiply the eligible loss by the 22% corporate tax rate to find the potential cash amount

This calculation helps you understand the liquidity effect of R&D activities when your business is not yet profitable.

8. Factor in group taxation and carry-forward of losses

If your company is part of a Danish tax group, R&D deductions in one group company can reduce the taxable income of other group entities. When calculating the overall benefit for the group, you should:

• Aggregate qualifying R&D costs across all group companies within the joint taxation scheme
• Apply the 22% rate to the group’s consolidated taxable income after R&D deductions
• Track any remaining losses that are carried forward to future years

The value of R&D deductions may therefore extend beyond the individual company that incurs the costs.

9. Build a simple internal calculation model

For planning and budgeting, many businesses create a straightforward calculation model, for example in a spreadsheet, that includes:

• Separate tabs for each R&D project, listing all expected cost categories
• Allocation keys for shared resources (percentage of time, usage, or space)
• Automatic calculation of total qualifying R&D expenditure
• Application of the 22% corporate tax rate to show the tax value
• Scenarios for profit and loss situations, including the impact on tax losses and possible cash payments

This kind of model allows you to update figures during the year and immediately see how changes in project scope or staffing affect your expected tax benefit.

10. Validate your calculation against documentation

Before finalising your R&D tax calculation for the tax return, cross-check your figures with underlying documentation:

• Payroll records and time sheets for staff included in the R&D cost base
• Invoices and contracts for external services and materials
• Fixed asset registers and depreciation schedules for equipment used in R&D
• Project descriptions, budgets and progress reports that demonstrate the R&D nature of the work

Aligning your calculation with solid evidence reduces the risk of adjustments during a tax audit and ensures that your business captures the full value of the R&D tax incentives available under Danish law.

The Difference Between R&D Tax Credits and Tax Deductions

When planning or evaluating research and development activities in Denmark, it is essential to understand the practical difference between an R&D tax credit and a tax deduction. Both mechanisms reduce your overall tax burden, but they do so in different ways and can have very different cash-flow effects for your business.

In the Danish corporate tax system, R&D support is primarily structured as an enhanced tax deduction with an option for a cash refund of tax losses related to R&D costs. While the term “R&D tax credit” is often used in international discussions, in Denmark the key benefit is not a separate percentage credit against tax, but an increased deduction base and the possibility to convert R&D-related tax losses into cash, subject to specific limits.

How a tax deduction works for R&D in Denmark

A tax deduction reduces your taxable income, not the tax itself. In Denmark, qualifying R&D expenses can generally be deducted at up to 130% of the actual cost. This means that if your company spends DKK 1,000,000 on eligible R&D, you may be able to deduct DKK 1,300,000 from your taxable income, provided the enhanced deduction rules are met.

With the current Danish corporate income tax rate of 22%, the tax saving from a 130% deduction can be illustrated as follows:

• Actual R&D cost: DKK 1,000,000
• Tax deduction at 130%: DKK 1,300,000
• Tax saving: 22% × 1,300,000 = DKK 286,000

Without the enhanced deduction, the tax saving would be 22% × 1,000,000 = DKK 220,000. The additional benefit from the R&D regime is therefore DKK 66,000 in this example. The value of the deduction always depends on your company’s taxable profit: if you do not have sufficient taxable income, the immediate effect of the deduction is limited, unless you can make use of the loss refund mechanism.

How a tax credit would work in principle

A tax credit, in contrast, directly reduces the tax payable. If Denmark offered a classic R&D tax credit at, for example, 10% of eligible costs, a DKK 1,000,000 qualifying R&D spend would generate a DKK 100,000 credit that is offset directly against your corporate tax bill.

The key conceptual differences are:

• A deduction lowers the income on which tax is calculated.
• A credit lowers the tax amount after it has been calculated.
• The value of a deduction depends on the tax rate; the value of a credit depends on the credit percentage.

In many countries, R&D tax credits can be refundable or carried forward. In Denmark, the system achieves a similar effect through the possibility of a refund of tax losses related to R&D costs, rather than through a standalone percentage credit.

Refund of R&D-related tax losses in Denmark

If your Danish company is in a tax loss position due to significant R&D investments, you may be able to receive a cash refund of the tax value of the R&D-related loss. The refund is generally calculated at the corporate tax rate of 22% and is subject to an annual cap on the amount of R&D costs that can generate a refundable loss.

For example, if your eligible R&D expenses create a tax loss of DKK 2,000,000 and the entire loss qualifies for refund, the potential cash refund is:

• Refundable loss: DKK 2,000,000
• Refund rate: 22%
• Cash refund: DKK 440,000

This mechanism functions similarly to a refundable R&D tax credit, even though, legally, it is a refund of the tax value of an R&D-related loss rather than a separate credit percentage. The refund is, however, limited by statutory ceilings on the amount of R&D costs that can be converted into a refundable loss each year, and by strict documentation and timing requirements.

Comparing the impact: deduction vs. “credit-like” refund

From a planning perspective, the main differences between relying solely on the enhanced deduction and using the loss refund mechanism are:

• Timing of the benefit: A deduction reduces tax only when you have taxable profits. The loss refund can generate cash even when you are not yet profitable, which is particularly important for start-ups and scale-ups.
• Cash flow: The refund provides a direct cash inflow based on your R&D-related loss, improving liquidity. The deduction improves your effective tax rate but may not provide immediate cash if your company is still in a loss-making phase.
• Ceilings and conditions: The enhanced deduction and the refund are both subject to eligibility rules and documentation requirements. The refund is additionally constrained by annual caps on the amount of R&D costs that can be converted into a refundable loss.

When comparing the Danish regime with systems in other jurisdictions, it is important to translate the enhanced deduction and the 22% refund of R&D-related losses into an “effective support rate” on your R&D spending. This helps you evaluate whether the Danish framework provides a higher or lower level of incentive compared with a classic R&D tax credit at a fixed percentage.

Which mechanism is more valuable for your business?

The relative value of a deduction versus a credit-like refund depends on your company’s situation:

• Profitable, established companies often benefit most from the 130% deduction, which permanently lowers the effective tax burden on R&D-intensive activities.
• Early-stage or fast-growing companies that are not yet profitable may derive more value from the refund of R&D-related tax losses, as it provides cash support during the development phase.

In practice, Danish companies frequently combine both elements over the life cycle of an R&D project: using the loss refund in the early years to support cash flow, and then leveraging the enhanced deduction once the business becomes profitable. Understanding how these mechanisms interact, and how they differ from a traditional R&D tax credit, is crucial for accurately forecasting the net cost of innovation projects and for designing a tax-efficient R&D strategy in Denmark.

Common Pitfalls in R&D Tax Credit Applications and How to Avoid Them

R&D tax incentives in Denmark can significantly reduce the cost of innovation, but many businesses lose part of the benefit due to avoidable mistakes in their applications. Below are the most common pitfalls companies face when claiming Danish R&D tax relief and practical ways to avoid them.

1. Misclassifying Routine Work as R&D

A frequent issue is treating ordinary product development or routine improvements as eligible R&D. Danish tax rules require that R&D activities involve a genuine element of novelty or technological or scientific uncertainty. Simply adapting existing solutions, performing standard testing, or making cosmetic changes to a product will usually not qualify.

To avoid this, clearly distinguish between:

• Work that aims to resolve technical or scientific uncertainties, and
• Work that implements, markets, or maintains already known solutions.

In your documentation, describe the uncertainty you faced, the hypotheses you tested, and why the outcome could not be reliably predicted in advance.

2. Inadequate Project Descriptions

Many applications fail because the project description is too vague or written in purely commercial terms. Tax authorities need to understand the technical or scientific content of the work, not just the business opportunity.

When preparing your description, make sure you:

• Explain the starting point: what was already known and available
• Define the specific technical or scientific challenges you aimed to solve
• Describe your approach, experiments, prototypes, and iterations
• Summarise the results, including partial successes and failures

A concise, technically focused narrative improves the chances that your activities will be recognised as R&D.

3. Poor Time Tracking for R&D Staff

Another common pitfall is claiming staff costs without reliable evidence of how much time employees actually spent on R&D. Estimations made after the year-end, without supporting records, are often challenged.

To avoid this, implement a simple but consistent time-tracking system. It should:

• Allocate hours to specific R&D projects
• Differentiate between eligible R&D tasks and non-eligible work (such as sales, support, or routine production)
• Be updated regularly by the employees themselves or their managers

Accurate time records make it easier to justify salary allocations and reduce the risk of adjustments during a tax audit.

4. Including Non-Eligible Costs

Companies often overclaim by including costs that are not directly related to R&D activities. Typical examples are general marketing expenses, ordinary maintenance, administrative overheads beyond allowed allocations, or costs related to production and distribution.

Eligible costs usually include:

• Salaries and social security contributions for staff directly involved in R&D
• Materials and components used in experiments, prototypes, and testing
• External consultancy and subcontractor costs directly linked to R&D tasks
• Depreciation of equipment used for R&D, in proportion to its R&D use

Review your cost categories carefully and exclude any expenses that are only indirectly connected to R&D or relate to commercial exploitation after the R&D phase.

5. Weak Separation Between R&D and Production

In many Danish companies, especially in manufacturing and technology, R&D and production are closely integrated. This can lead to confusion about which activities are eligible. For example, scaling up a proven prototype to full production is usually not R&D, even if it requires engineering work.

To avoid this pitfall, define clear internal phases for your projects, such as:

• Concept and feasibility
• Experimental development and prototyping
• Pilot testing and validation
• Industrialisation and routine production

Only allocate costs to R&D for the phases where you are still resolving technical or scientific uncertainties. Once the solution is stable and repeatable, further work is generally not eligible.

6. Insufficient Technical Involvement in the Application

Applications prepared solely by finance or administrative staff, without input from engineers, developers, or researchers, often lack the technical depth required by the tax authorities.

Involve your technical teams when:

• Defining which projects qualify as R&D
• Describing the uncertainties, methods, and results
• Estimating the proportion of time spent on eligible activities

This collaboration helps ensure that the application accurately reflects the real content of the work and uses terminology that tax reviewers can understand and verify.

7. Missing or Disorganised Documentation

Even if your activities are clearly R&D, you can still lose tax benefits if you cannot provide evidence. Common documentation gaps include missing project plans, incomplete experiment records, or lack of supporting invoices and contracts.

To strengthen your position, keep:

• Project charters, roadmaps, and design documents
• Lab notes, test protocols, and test reports
• Version histories, code repositories, and change logs for software projects
• Contracts and invoices for external R&D services
• Internal approvals and board minutes related to major R&D decisions

Organise these documents by project and year so they can be easily presented if the tax authorities request additional information.

8. Ignoring Subcontractor and Collaboration Issues

Many Danish businesses collaborate with universities, research institutions, or foreign partners, or they outsource parts of their R&D. Problems arise when it is unclear who owns the results, who bears the risk, and which party is entitled to claim the tax benefits.

Before you submit a claim, clarify:

• Which entity is the main R&D owner and decision-maker
• How costs are shared and invoiced between partners
• Whether any public grants or subsidies reduce the amount of eligible expenditure

Ensure that your contracts reflect the actual R&D responsibilities and that you only claim costs that you genuinely bear and that are not already funded by other public support.

9. Overlooking the Interaction with Other Tax Rules

R&D tax incentives interact with other parts of the Danish tax system, such as rules on depreciation, loss carryforwards, and the treatment of grants. Errors often occur when companies claim the same cost twice in different ways or fail to adjust for subsidies.

When calculating your R&D tax base, check whether:

• Any part of the cost has been reimbursed by public grants or EU funding
• You have already benefited from special depreciation or other tax incentives for the same assets
• Your treatment of R&D costs is consistent between the tax return, financial statements, and internal project accounts

A coherent approach reduces the risk of corrections and penalties during a tax review.

10. Missing Deadlines and Formal Requirements

Some businesses lose their right to claim R&D tax relief because they miss statutory deadlines or fail to submit required forms and attachments with the tax return. Late or incomplete filings are often difficult or impossible to correct afterwards.

To prevent this, establish an internal calendar that covers:

• Year-end cut-off for collecting R&D data from departments
• Deadlines for preparing and reviewing project descriptions and cost summaries
• Final filing deadlines for the corporate tax return and any specific R&D schedules

Assign clear responsibilities within your finance and R&D teams so that all required information is ready well before the filing date.

11. Underclaiming Due to Excessive Caution

While overclaiming is risky, some companies take the opposite approach and claim far less than they are entitled to, especially when they are unsure whether a project qualifies. This can mean leaving substantial tax benefits unused.

If a project involves genuine technical or scientific uncertainty and systematic investigation, it may be eligible even if it ultimately fails. Do not exclude projects solely because they did not lead to a marketable product. Instead, document the uncertainties and the learning outcomes, and assess them against the formal R&D criteria.

12. How to Systematically Avoid These Pitfalls

The most effective way to avoid common mistakes is to treat R&D tax relief as an integrated part of your innovation process, not as a one-off exercise at year-end. Consider:

• Defining internal criteria for what your company considers R&D, aligned with Danish tax rules
• Tagging R&D projects in your accounting and project management systems from the start
• Training key staff in finance and R&D on eligibility rules and documentation standards
• Reviewing your R&D portfolio annually to identify all qualifying projects and costs

By building these practices into your normal operations, you reduce the risk of errors, strengthen your position in case of a tax audit, and ensure that your business captures the full value of the R&D tax incentives available in Denmark.

Deadlines You Need to Know for R&D Tax Relief in 2026

Timing is critical when planning and claiming tax relief for research and development activities in Denmark. Missing a deadline can mean losing access to valuable cash refunds or deductions, even if your project clearly qualifies as R&D. Below you will find the key dates and time limits that companies should keep in mind for R&D tax relief in the Danish system for the 2026 income year.

R&D costs and the 130% tax deduction – income year 2026

In Denmark, qualifying R&D expenses can generally be deducted at 130% for corporate income tax purposes, subject to the rules in the Danish Tax Assessment Act. For the 2026 income year, the decisive factor is when the costs are incurred and which income year they are allocated to in your accounts and tax return.

Key timing points include:

• R&D expenses must be incurred within the company’s 2026 income year to be included in the 130% deduction for that year.
• The deduction is claimed as part of the ordinary corporate tax return for 2026, not in a separate R&D form.
• If you use a non-calendar income year, the relevant period is your financial year that falls within the 2026 tax year; the same filing deadlines apply, counted from the end of your income year.

Corporate tax return deadline for 2026

The main deadline for claiming the 130% R&D deduction is the deadline for filing the corporate tax return with the Danish Tax Agency (Skattestyrelsen). For companies using the standard calendar year as their income year, the corporate tax return for 2026 must typically be filed no later than six months after the end of the income year.

For a company with a calendar income year (1 January–31 December 2026):

• The corporate tax return, including the R&D deduction, must normally be submitted by the end of the following June.
• Any extension granted by Skattestyrelsen will also extend the time for reporting R&D expenses, but only within the framework of the general rules on late filing and penalties.

Because the R&D deduction is embedded in the tax return, failing to file on time can delay or reduce the benefit and may trigger interest and surcharges on any underpaid tax.

Deadlines for R&D tax credit (cash refund) on losses

In addition to the enhanced deduction, Danish rules allow certain companies to convert part of their tax loss arising from R&D expenses into a cash refund (R&D tax credit). The timing here is also linked to the corporate tax return.

Important timing aspects for the 2026 income year include:

• The request for an R&D tax credit must be made in the corporate tax return for 2026; there is no separate standalone deadline.
• The same filing deadline applies as for the tax return itself (normally six months after the end of the income year).
• The refund is processed after Skattestyrelsen has received and reviewed the tax return; delays in filing will postpone the payment of the credit.

If you discover additional qualifying R&D costs after filing, you may be able to submit a corrected return within the general reassessment period, but any correction must still respect the statutory time limits for changing tax assessments.

Reassessment and correction deadlines

Danish tax law allows Skattestyrelsen to reassess a company’s tax position for a limited number of years back. This also sets an outer time limit for correcting or supplementing R&D claims for 2026.

Key points to consider:

• The ordinary reassessment period generally runs for several years from the end of the income year; within this period, both the company and Skattestyrelsen may request changes to the tax assessment, including R&D deductions and credits.
• After the ordinary reassessment period expires, it becomes significantly harder to adjust R&D claims, and in practice the possibility to increase your R&D benefit for 2026 may be lost.
• In cases of serious errors or omissions, extended reassessment rules may apply, but these are exceptional and should not be relied upon as part of normal planning.

Internal planning deadlines for 2026 R&D projects

Beyond the formal legal deadlines, companies should establish internal cut-off dates to ensure that all qualifying R&D costs are identified, documented and approved before the 2026 tax return is prepared.

For effective planning, consider:

• Setting an internal deadline several weeks before the statutory filing date to finalise the list of R&D projects and related costs.
• Ensuring that time sheets, subcontractor invoices and technical documentation for 2026 projects are collected and archived before year-end closing.
• Reviewing borderline projects early, so that any uncertainties about eligibility can be clarified before the tax return is submitted.

Consequences of missing R&D tax relief deadlines

Missing or ignoring deadlines can have direct financial consequences for your 2026 R&D benefits:

• Late filing of the corporate tax return can lead to penalties and interest, and may delay or reduce the R&D tax credit.
• Failure to include R&D expenses in the 2026 return may mean that only a later correction within the reassessment period can restore the benefit, which can be administratively burdensome.
• If the reassessment period expires before you correct your return, the opportunity to claim additional R&D relief for 2026 may be permanently lost.

To protect your position, it is advisable to treat R&D tax relief as an integral part of your year-end and tax compliance process, not as an afterthought once the statutory deadlines are approaching.

How R&D Tax Relief Contributes to Innovation and Growth

R&D tax relief in Denmark is designed not only to reduce the immediate tax burden for companies, but also to stimulate long-term innovation, productivity and sustainable growth across the economy. By lowering the effective cost of research and development activities, the Danish tax system encourages businesses to invest in new technologies, digitalisation, green solutions and process improvements that might otherwise be considered too risky or capital-intensive.

One of the most direct ways R&D tax relief supports innovation is through the possibility of an immediate cash refund of a portion of R&D-related tax losses. Companies can apply for a refund of up to 25% of tax losses attributable to qualifying R&D costs, calculated at the corporate tax rate of 22%. The refund is capped at DKK 25 million of R&D costs per income year, which means that a company can receive up to DKK 5.5 million in cash. This mechanism is particularly important for start-ups and scale-ups that invest heavily in development but do not yet generate taxable profits. It improves liquidity at a critical stage, allowing them to hire specialised staff, purchase equipment and extend development timelines without relying solely on external financing.

For profitable companies, R&D tax relief reduces the effective cost of innovation by allowing qualifying expenses to be deducted from taxable income. This includes wages for employees directly involved in R&D, certain consultancy fees, materials used in experimental activities and a proportion of overheads linked to development projects. The tax deduction lowers the overall tax bill, freeing up capital that can be reinvested in further development, testing, market expansion or intellectual property protection. Over time, this supports a continuous innovation cycle rather than one-off projects.

At the macroeconomic level, R&D tax incentives contribute to higher productivity and competitiveness in Denmark. When companies can reduce the net cost of innovation, they are more likely to develop new products, improve energy efficiency, automate processes and adopt advanced digital tools. This leads to higher value-added production, stronger export potential and more resilient business models. The cumulative effect is a more innovative business environment that attracts both domestic and foreign investment in research-intensive sectors such as life sciences, clean technology, advanced manufacturing and software development.

R&D tax relief also plays a role in strengthening collaboration between businesses, universities and research institutions. Danish companies that engage in joint research projects or contract research can often include these costs in their R&D tax base, provided they meet the statutory criteria for research and development. This creates a financial incentive to participate in innovation ecosystems, share knowledge and accelerate the commercialisation of scientific results. In practice, this can shorten time-to-market for new solutions and increase the likelihood that research outcomes translate into viable products and services.

Another important contribution of R&D tax relief is its impact on high-skilled employment. Because wages for employees directly engaged in R&D are typically a major component of eligible costs, the tax rules effectively support the creation and retention of specialised jobs in engineering, IT, data science and other technical fields. Companies are more inclined to build in-house development teams, invest in upskilling and offer long-term contracts when a portion of these costs is offset through the tax system. This helps Denmark maintain a strong talent base and supports regional development, as R&D-intensive companies often act as anchors in local innovation clusters.

From a strategic perspective, R&D tax relief encourages companies to think in terms of structured, long-term development portfolios rather than ad hoc experimentation. To benefit from the incentives, businesses must document their projects, define objectives, describe technological or scientific uncertainties and track eligible costs. This requirement often leads to better project management, clearer innovation roadmaps and more robust decision-making about which initiatives to pursue. As a result, companies not only gain tax benefits but also improve their internal governance around innovation.

R&D tax incentives in Denmark also support the transition to a greener and more sustainable economy. Many qualifying projects focus on reducing emissions, improving resource efficiency, developing circular business models or creating climate-friendly technologies. By lowering the after-tax cost of these projects, the tax system helps align corporate innovation strategies with national climate and sustainability goals. This can include, for example, investments in energy-efficient production methods, new materials with a lower environmental footprint or digital solutions that optimise energy use.

Finally, R&D tax relief contributes to growth by reducing the risk associated with entering new markets or developing breakthrough technologies. Even when a project does not lead to immediate commercial success, the tax benefits soften the financial impact of unsuccessful experiments, making it more acceptable for companies to explore ambitious ideas. Over time, this higher tolerance for calculated risk is essential for breakthrough innovation and for maintaining Denmark’s position as a knowledge-based, innovation-driven economy.

Practical Examples of Companies That Have Benefited from R&D Tax Credits

Understanding how the Danish R&D tax rules work in practice is often easier when you look at concrete examples. Below are illustrative scenarios based on typical Danish businesses. They are simplified and anonymised, but they reflect realistic use of R&D tax credits and enhanced deductions under current Danish tax legislation.

Example 1: Tech start-up developing a SaaS platform

A Copenhagen-based start-up is building a cloud-based platform that uses machine learning to optimise logistics routes. The company has 8 employees, of which 5 are software developers and data scientists working almost exclusively on R&D.

In one income year, the company incurs the following qualifying R&D costs:

• Salaries for R&D staff (including pension and social contributions): DKK 3,200,000
• External consultants for algorithm development: DKK 350,000
• Cloud infrastructure and test environments directly linked to R&D: DKK 250,000
• Prototypes and testing tools: DKK 200,000

Total qualifying R&D expenditure: DKK 4,000,000.

Under the enhanced deduction rules, the company can deduct more than 100% of these costs when calculating taxable income. If the enhanced deduction rate is, for example, 130%, the tax-deductible amount becomes:

DKK 4,000,000 × 130% = DKK 5,200,000 deductible for corporate tax purposes.

Assuming the standard Danish corporate tax rate of 22%, the tax value of the additional 30% deduction (DKK 1,200,000) is:

DKK 1,200,000 × 22% = DKK 264,000 in extra tax savings compared with a normal 100% deduction.

Because the start-up is not yet profitable, it also applies for a cash refund of the tax value of its R&D-related tax loss. If the company’s total tax loss for the year is DKK 3,000,000, of which DKK 2,500,000 is attributable to qualifying R&D, it can request a refund of:

DKK 2,500,000 × 22% = DKK 550,000 as a cash payment from the tax authorities, subject to the annual cap on refundable R&D losses.

This liquidity boost helps the start-up finance additional developers and extend its runway without raising extra equity.

Example 2: Manufacturing company automating its production line

A medium-sized manufacturer in Jutland produces components for the wind energy sector. To stay competitive, the company invests in developing a new automated production line that uses advanced sensors and robotics. The project involves significant technical uncertainty and requires custom software and mechanical design.

Over the year, the company incurs the following R&D-related costs:

• Engineers’ and technicians’ salaries allocated to R&D: DKK 5,500,000
• Materials and components used in prototypes and test runs: DKK 900,000
• External testing and certification directly linked to the R&D project: DKK 600,000

Total qualifying R&D expenditure: DKK 7,000,000.

Using an enhanced deduction rate of 130%, the company can deduct:

DKK 7,000,000 × 130% = DKK 9,100,000 from its taxable income.

At a 22% corporate tax rate, the total tax saving from the R&D deduction is:

DKK 9,100,000 × 22% = DKK 2,002,000.

If the company had only been able to deduct 100% of the costs (DKK 7,000,000), the tax saving would have been:

DKK 7,000,000 × 22% = DKK 1,540,000.

The enhanced deduction therefore generates an additional tax benefit of:

DKK 2,002,000 − DKK 1,540,000 = DKK 462,000.

This extra saving improves the project’s internal rate of return and supports further investments in digitalisation and green technologies.

Example 3: Life science company running clinical trials

A Danish biotech company is developing a new medical device. The project includes laboratory research, prototype development and early-stage clinical trials conducted with Danish and international partners.

During the year, the company records the following R&D costs:

• In-house R&D staff (researchers, lab technicians, regulatory specialists): DKK 9,000,000
• Clinical trial costs paid to hospitals and CROs: DKK 4,000,000
• Specialised lab equipment used primarily for the R&D project: DKK 2,000,000

Total qualifying R&D expenditure: DKK 15,000,000.

The company is still in the development phase and generates no taxable profit. It therefore focuses on the possibility of a cash refund of the tax value of its R&D-related tax loss.

If the company’s total tax loss for the year is DKK 12,000,000 and all of it relates to qualifying R&D activities, the tax value of this loss at 22% is:

DKK 12,000,000 × 22% = DKK 2,640,000.

Subject to the statutory annual ceiling on refundable R&D losses, the company can receive this amount as a cash refund. This significantly reduces the need for short-term financing and allows the business to continue its trials without delaying milestones.

Example 4: SME improving an existing product line

A small Danish food producer wants to develop a new, longer-lasting packaging solution that reduces food waste and meets stricter environmental requirements. The project involves experimenting with new materials and testing different barrier properties and sealing technologies.

Qualifying R&D costs for the year include:

• R&D team salaries: DKK 1,400,000
• Materials and test batches: DKK 300,000
• External laboratory analyses: DKK 200,000

Total qualifying R&D expenditure: DKK 1,900,000.

With an enhanced deduction rate of 130%, the deductible amount is:

DKK 1,900,000 × 130% = DKK 2,470,000.

At a 22% tax rate, the R&D deduction yields a tax saving of:

DKK 2,470,000 × 22% = DKK 543,400.

Without the enhanced deduction, the tax saving on a 100% deduction would have been:

DKK 1,900,000 × 22% = DKK 418,000.

The additional benefit from the R&D incentive is therefore:

DKK 543,400 − DKK 418,000 = DKK 125,400.

For a small business, this extra amount can finance further product testing, marketing for the new packaging or investment in more efficient production equipment.

What these examples show

Across different sectors and company sizes, the Danish R&D tax regime can:

• Increase the tax value of R&D expenditure through enhanced deductions
• Provide cash refunds of R&D-related tax losses for companies without taxable profits
• Improve liquidity and reduce the effective cost of innovation projects

In all cases, the key to benefiting from R&D tax incentives is to clearly document which activities qualify as R&D, track related costs accurately and apply the correct deduction and refund rules when preparing the tax return.

The Impact of R&D Tax Relief on Start-ups and SMEs in Denmark

Research and development tax relief plays a particularly important role for start-ups and small and medium-sized enterprises (SMEs) in Denmark. Because these businesses often operate with tight cash flow and limited access to external financing, the ability to deduct R&D costs at a favourable rate – and, in many cases, convert tax losses into a cash refund – can significantly improve liquidity, reduce risk and accelerate growth.

Under the Danish rules, companies can generally deduct 100% of qualifying R&D expenses as operating costs. In addition, they may choose to apply an uplift of up to 130% on eligible R&D expenditure for tax purposes, within the limits set by Danish tax law. For loss-making start-ups and SMEs, the possibility to obtain a cash reimbursement of a portion of the tax value of these losses, up to a capped amount per income year, can be crucial in the early stages of development when revenues are still low or irregular.

For innovative start-ups, this relief often bridges the gap between concept and commercialisation. R&D-intensive companies in sectors such as software, life sciences, clean technology, advanced manufacturing or design can allocate more budget to hiring specialised staff, purchasing equipment, testing prototypes and protecting intellectual property. Instead of diverting resources to cover immediate tax liabilities, founders can reinvest the tax savings directly into product development and market entry.

SMEs that are already generating revenue benefit in a slightly different way. R&D tax relief allows them to scale existing projects, expand their development teams and explore new technologies without proportionally increasing their tax burden. The enhanced deduction reduces taxable income, which can lower the effective corporate tax rate on innovative activities. This makes it more attractive for established SMEs to maintain in-house development rather than outsourcing or postponing projects due to cost concerns.

Another important impact is on access to external capital. Investors and lenders increasingly look at how efficiently a company uses available public incentives. A clear R&D strategy that systematically captures eligible costs and claims tax relief signals professional financial management and reduces the perceived risk of long-term innovation projects. For many Danish start-ups, demonstrating consistent use of R&D tax relief has become part of the standard narrative in discussions with venture capital funds, business angels and banks.

R&D tax relief also encourages collaboration. Because eligible costs can include salaries, consultancy fees and certain subcontracted R&D services, start-ups and SMEs are more inclined to work with universities, research institutions and specialised technology providers. This not only improves the quality of innovation, but also helps smaller companies integrate into broader Danish and international innovation ecosystems, where they can access knowledge, talent and new markets.

From a strategic perspective, tax relief can change how founders and managers plan their development roadmap. Instead of focusing solely on short-term, low-risk improvements, they are more likely to invest in longer-term, higher-risk projects with greater innovation potential. Over time, this can lead to stronger intellectual property portfolios, more scalable business models and higher company valuations, which are particularly important for start-ups preparing for funding rounds or exits.

However, to fully benefit from these incentives, start-ups and SMEs must treat R&D tax relief as an integral part of their financial planning rather than an afterthought. This means identifying eligible projects early, tracking R&D hours and costs in sufficient detail, and ensuring that project descriptions clearly demonstrate the technological or scientific uncertainty and systematic experimentation required by Danish tax rules. When this is done properly, the administrative effort is usually outweighed by the financial advantages.

Overall, R&D tax relief in Denmark acts as a lever that amplifies the impact of every krone invested in innovation by start-ups and SMEs. It reduces the effective cost of development, improves cash flow during critical growth phases, supports collaboration and strengthens the investment case for innovative businesses. For many smaller companies, understanding and using these tax benefits is not just an optimisation tool, but a key component of building a sustainable, competitive position in the Danish and international markets.

What Changes to Expect in Denmark's R&D Tax System Post-2026

While the current Danish R&D tax rules provide a relatively stable framework, businesses should expect adjustments to the system after 2026. These changes are likely to focus on aligning R&D incentives with green transition goals, digitalisation and stricter EU state aid rules, rather than on abolishing support altogether. Understanding the possible directions of reform will help you plan long-term projects and investment decisions more confidently.

At present, companies can deduct 130% of eligible R&D expenses when calculating taxable income, and loss-making companies can apply for a cash refund of the tax value of R&D costs of up to DKK 25 million per income year (corresponding to a maximum refund of DKK 5.5 million at the 22% corporate tax rate). Any post‑2026 reform is expected to reassess these parameters, not the principle of supporting R&D itself.

Possible adjustments to deduction rates and refund caps

One of the most likely areas for change is the level of enhanced deduction and the annual cap for cash refunds. Policymakers may:

• Reduce or increase the 130% deduction rate, for example by returning closer to a 110–120% range, or by introducing a tiered rate that favours smaller companies
• Adjust the DKK 25 million cap on R&D costs eligible for cash refund, either by raising it to stimulate large-scale innovation or lowering it to target support more directly at SMEs
• Introduce separate caps for different types of R&D (for example, experimental development versus basic research) to steer investment into priority areas

If your business relies heavily on the cash refund mechanism, it is prudent to model scenarios where the cap is reduced or the enhanced deduction is scaled back, and to consider how this would affect liquidity and project timing.

Stronger focus on green and digital R&D

Denmark is steadily integrating climate and sustainability objectives into its tax and subsidy framework. After 2026, R&D tax incentives may increasingly reward projects that contribute to:

• Reducing CO₂ emissions in production, logistics or energy consumption
• Developing renewable energy technologies, energy storage or power‑to‑X solutions
• Improving resource efficiency, circular economy models and waste reduction
• Digitalisation, automation and AI‑driven optimisation of industrial processes

This could take the form of higher deduction rates for qualifying “green” or “digital” R&D, additional documentation requirements to prove environmental impact, or special reporting fields in the tax return. Companies that already track environmental and digital KPIs at project level will be better positioned to benefit from such targeted incentives.

Tighter definitions and documentation standards

Across Europe, tax authorities are moving towards more precise definitions of what qualifies as R&D for tax purposes. In Denmark, this may translate into:

• More detailed criteria distinguishing routine product updates from genuine R&D
• Clearer boundaries between software development that qualifies and that which is considered standard implementation or maintenance
• Stricter requirements to document technological uncertainty, hypotheses, test results and project milestones
• Greater emphasis on contemporaneous documentation rather than retrospective justifications

Post‑2026, you should expect the Danish Tax Agency to scrutinise borderline projects more closely, particularly in sectors such as IT, life sciences and engineering services. Building a robust internal process for classifying and documenting R&D now will reduce the risk of future adjustments and disputes.

Closer alignment with EU state aid and international rules

Denmark’s R&D tax system must remain compatible with EU state aid regulations and international tax standards, including the evolving global minimum tax framework. Future changes may therefore involve:

• Refining rules to ensure that R&D incentives do not conflict with minimum effective tax rate requirements for large multinational groups
• Adjusting the treatment of cross‑border R&D activities, including costs incurred in other EU/EEA countries
• Introducing clearer guidance on transfer pricing for intra‑group R&D and cost‑sharing arrangements

Groups that centralise R&D in Denmark or allocate significant development functions to Danish entities should monitor how these international developments are implemented locally, as they may affect both the amount of relief and the required documentation.

Greater differentiation between start‑ups and large enterprises

Another likely trend is a more differentiated system that offers stronger support to start‑ups and SMEs, while tightening conditions for large corporations. This could include:

• Higher effective support (for example, a higher refund cap or enhanced deduction) for companies below a certain turnover or headcount threshold
• Simplified application and documentation procedures for smaller businesses
• More detailed review and possible pre‑approval requirements for very large R&D claims from multinational groups

If you are a growing company close to SME thresholds, it will be important to understand how crossing these thresholds might affect your access to favourable R&D tax treatment in the years after 2026.

What your business can do now

Although the exact post‑2026 rules are not yet defined, you can prepare by:

• Mapping all current and planned R&D projects, including expected costs and timelines
• Implementing project‑based tracking of R&D expenses, broken down by type of activity and business unit
• Strengthening documentation practices so they meet stricter future standards without major process changes
• Assessing your exposure to potential reductions in deduction rates or refund caps
• Monitoring legislative proposals and guidance from the Danish Tax Agency and Ministry of Taxation

By building flexible internal processes and staying informed, your company can adapt quickly to any changes in Denmark’s R&D tax system after 2026 and continue to secure the maximum available tax benefits for innovation activities.

How to Stay Compliant and Avoid Audits in R&D Tax Claims

Staying compliant with Danish R&D tax rules is essential if you want to benefit from the available incentives while minimising the risk of audits, corrections and penalties. The Danish Tax Agency (Skattestyrelsen) increasingly uses data analytics to review R&D claims, so your documentation, calculations and internal processes must be consistent, transparent and aligned with current legislation and guidance.

Compliance starts with a clear internal definition of what your business considers to be research and development. This definition should mirror the criteria applied by the Danish authorities: projects must aim to generate new knowledge or significantly improve products, services or processes, and they must involve a systematic, planned approach with technical or scientific uncertainty. Routine improvements, cosmetic changes or purely commercial activities should be explicitly excluded from your internal R&D scope to avoid overclaiming.

To reduce audit risk, you should maintain a formal R&D policy approved by management. This policy should describe how projects are identified as R&D, who is responsible for classification decisions, how costs are tracked, and how often the criteria are reviewed. When tax inspectors see that your company has a structured approach rather than ad hoc decisions, they are more likely to view your claims as reliable.

Robust documentation is the core of compliance. For each R&D project, you should keep a concise but complete project file that includes the business objective, technical challenges, planned activities, milestones and final outcomes. Technical reports, design documents, test protocols, lab notes, code repositories and meeting minutes all help demonstrate that the work meets the R&D definition. These documents should be dated, version-controlled and linked clearly to the relevant project.

Equally important is accurate tracking of R&D costs. You should ensure that salary expenses, subcontractor fees, materials, software licences and other eligible costs are recorded in a way that allows you to separate R&D from non-R&D activities. Time registration systems are particularly critical for staff who split their work between R&D and routine operations. Timesheets should be filled in regularly, approved by supervisors and reconciled with payroll records so that the hours claimed can be verified during an audit.

When calculating your R&D tax benefit, you must apply the current Danish rules consistently. This includes using the correct percentage rates for enhanced deductions or credits, respecting any ceilings or thresholds on eligible costs, and ensuring that you do not claim the same expenditure under multiple incentive schemes. If you receive grants or subsidies that cover part of your R&D expenses, you need to adjust your tax calculations accordingly so that only the net cost borne by your company is included.

Internal controls play a major role in preventing errors that can trigger audits. You should implement a review process in which someone other than the person preparing the claim checks the project list, eligibility assessments, cost allocations and final tax calculations. This second-level review should be documented, with clear sign-off and any corrections recorded. For larger businesses, periodic internal audits of R&D projects and claims can help identify weaknesses before the tax authorities do.

Another important compliance measure is to ensure alignment between your R&D tax claim and other information you submit to Danish authorities. Descriptions of projects in annual reports, grant applications, patent filings and transfer pricing documentation should not contradict the way you present the same projects in your tax return. Inconsistent descriptions can raise red flags and lead to more detailed questions from Skattestyrelsen.

Communication with your technical teams is essential. Engineers, developers and researchers often have the best understanding of what is genuinely innovative, but they may not be familiar with tax rules. Regular training sessions and clear guidance help them document their work in a way that supports the tax claim. At the same time, your finance and tax staff should understand the technical context well enough to explain the projects convincingly during an audit.

To avoid disputes, it is wise to keep all supporting documentation for at least as long as the statutory limitation period for tax assessments in Denmark. This includes not only financial records but also technical evidence of R&D activities. Digital archiving with secure backups and clear indexing makes it easier to respond quickly and accurately if the tax authorities request information.

Monitoring regulatory changes is another key element of staying compliant. Danish R&D tax rules, thresholds and administrative practices can evolve, and the interpretation of what qualifies as R&D may be refined over time through updated guidance or case law. Assigning responsibility within your organisation for tracking these developments helps ensure that your future claims remain aligned with current expectations and that you adjust your processes when needed.

If you receive a query or information request from Skattestyrelsen, responding promptly, clearly and with complete documentation significantly reduces the risk of a full audit. You should answer the specific questions asked, provide structured evidence and avoid speculative explanations. If you discover an error in a previous claim, it is usually better to correct it proactively rather than wait for the authorities to identify it, as voluntary corrections are often viewed more favourably.

Finally, many businesses choose to involve external advisers with experience in Danish R&D tax incentives, especially when dealing with complex projects, cross-border activities or large claim amounts. While the responsibility for compliance always remains with your company, expert input can help you interpret grey areas, benchmark your practices against market standards and prepare more audit-resistant documentation.

By combining clear internal definitions, thorough documentation, reliable cost tracking, strong internal controls and proactive monitoring of regulatory changes, your business can confidently claim Danish R&D tax benefits while significantly reducing the likelihood of audits and disputes.

Maximizing Your Tax Benefits: Tips for Businesses Engaging in R&D

Maximizing the tax benefits available for research and development in Denmark starts with a clear strategy. Danish rules are relatively generous, but they reward businesses that plan ahead, document carefully and align their R&D activities with the formal tax definitions. The tips below focus on practical steps that help you secure and optimise R&D tax relief for 2026 and the following years.

1. Map your R&D activities early in the year

Begin each income year by identifying which projects are likely to qualify as R&D. Create a simple internal register that lists each project, its objectives, expected technological or scientific uncertainty, and the departments involved. This makes it easier to separate qualifying R&D costs from routine commercial work and to defend your claim in case of questions from the Danish Tax Agency.

2. Separate R&D costs from ordinary business expenses

To maximise your benefit, you need a clear cost structure. Set up dedicated cost centres or project codes in your accounting system for R&D. Track, at a minimum:

• Employee salaries and social contributions for staff directly involved in R&D
• Consumables and materials used in experiments, prototypes and testing
• External consultants and subcontractors working on R&D tasks
• Depreciation of equipment and software used primarily for R&D

Ensure that overheads and general administrative costs are only included where the rules explicitly allow it, and apply consistent allocation keys if you apportion shared costs between R&D and non-R&D activities.

3. Classify staff time accurately

Labour costs are often the largest component of an R&D tax claim. Implement time tracking or at least monthly estimates that distinguish between:

• Core R&D work (designing experiments, developing prototypes, resolving technical uncertainties)
• Supporting activities (documentation, internal reporting, project management directly tied to R&D)
• Non-qualifying work (routine production, sales, marketing, customer support)

Only the proportion of time spent on qualifying R&D should be included in the tax calculation. Having written job descriptions and project plans that show the R&D content of each role strengthens your position.

4. Align your projects with the Danish definition of R&D

For tax purposes, R&D must aim to create new knowledge or significantly improve products, processes or services by overcoming scientific or technological uncertainty. To maximise your claim:

• Document the uncertainty at the start of the project – what was not known or not solvable with existing standard solutions
• Describe the hypotheses, experiments and iterations you use to resolve that uncertainty
• Record both successful and unsuccessful attempts; failed experiments can still qualify as R&D

Avoid describing projects purely in commercial terms (for example, “launching a new product line”) without explaining the underlying technical challenges.

5. Use project documentation as evidence

Good documentation not only supports your claim but also helps you identify all eligible costs. Keep:

• Project charters, technical specifications and research plans
• Meeting minutes, experiment logs and test reports
• Version histories for prototypes, software and process designs
• Contracts and statements of work for external R&D partners

Make sure the documentation clearly links to the costs recorded in your accounting system, for example by using consistent project codes and naming conventions.

6. Optimise the choice between deduction and credit

Danish rules allow enhanced deductions for R&D costs and, under specific conditions, a cash tax credit for companies with tax losses. To maximise your benefit:

• Estimate your taxable income or loss for the year before R&D incentives
• Compare the value of an immediate cash credit with the value of carrying forward losses to offset against future profits
• Consider the company’s cash flow needs, financing plans and expected profitability in the next few years

For start-ups and SMEs that are not yet profitable, the cash credit can be particularly valuable, but it is still important to model the long-term impact on effective tax rates.

7. Coordinate R&D tax planning with other incentives

Many Danish businesses combine R&D tax relief with other forms of support, such as innovation grants, EU funding or regional programmes. To avoid double counting and to maximise the overall benefit:

• Check whether grants you receive are taxable income and whether they reduce the R&D cost base
• Ensure that the same cost is not subsidised twice in a way that conflicts with Danish or EU rules
• Align your project budgets so that funded and non-funded activities are clearly separated

Integrated planning helps you avoid later adjustments and potential repayments.

8. Involve finance, tax and technical teams together

The strongest R&D tax claims are prepared jointly by finance, tax and technical staff. Encourage:

• Technical teams to describe projects in language that reflects scientific or technological uncertainty
• Finance teams to design cost tracking that matches the tax rules
• Management to review the portfolio of R&D projects at least annually from a tax perspective

This cross-functional approach reduces the risk of missing eligible costs or including non-qualifying activities.

9. Review your R&D portfolio annually

At the end of each income year, perform a structured review of all projects that might qualify as R&D:

• Confirm which projects meet the tax definition and which do not
• Check that all relevant costs have been captured and correctly allocated
• Update your internal policies and templates based on any feedback from the Danish Tax Agency

Regular reviews help you refine your processes and increase the reliability of your claims over time.

10. Monitor legislative and practice changes

Danish R&D tax rules, thresholds and administrative practices can change, and the interpretation of what qualifies may evolve. To protect and maximise your benefits:

• Follow updates from the Danish Tax Agency and relevant ministries
• Adjust your documentation and cost tracking when new guidance is published
• Reassess long-term R&D projects if definitions or calculation methods are updated

Staying informed ensures that your business continues to claim the full relief it is entitled to, while remaining compliant.

By integrating these practices into your day-to-day operations, you increase the value of your R&D tax benefits in Denmark and reduce the risk of disputes or lost opportunities. Thoughtful planning, precise cost tracking and strong documentation are the key elements of an effective R&D tax strategy.
