WBSO grant: tax benefit on your research and development work

The WBSO is the best-known innovation scheme in the Netherlands. It reduces the payroll tax you pay for employees working on research and development, and also covers part of other project costs such as materials and prototypes. Curious what the WBSO can deliver for your organisation?

When does your work qualify for the WBSO?

Development projects focus on technically new products, production processes or software. For the WBSO, development ends as soon as the working principle has been demonstrated. Technical-scientific research covers research in the fields of physics, chemistry, biotechnology, production technology or communication technology.

Details about the WBSO

The WBSO grant is available to SMEs, large multinationals and self-employed entrepreneurs who are based in the Netherlands and carry out research and development (R&D) work.

To qualify for the WBSO, the development must be technically new for your company and developed in-house. It is important that the developments are still to take place, as this grant scheme does not apply retroactively.

WBSO stands for the Research and Development Promotion Act (Wet Bevordering Speur- en Ontwikkelingswerk) and reimburses part of the costs of R&D projects. With it, the government rewards entrepreneurs who engage in innovation and take a financial risk in doing so. S&O is the Dutch term derived from the English R&D (research & development).

The budget increase amounts to a structural € 200 million per year, further expanding the opportunities for entrepreneurs.

Through the WBSO grant, entrepreneurs working on the development or improvement of a product, service or process may deduct 50% of wage costs and material costs from payroll or income tax. This is an increase compared with the previous deduction of 40% for starters, mainly intended to boost start-ups with innovative ideas.

In addition, the rate of the first bracket is 36%, and 50% for starters. The first bracket is also extended from € 380,000 to € 391,020. These adjustments particularly stimulate smaller investments, for which the WBSO is used most.

Material costs include, among other things, costs for prototypes, test set-ups, machines or laboratories. In practice, using the Research and Development Promotion Act for innovative projects quickly yields a company thousands to tens of thousands of euros.

Did you know that you can also gain a tax benefit through the Innovation Box scheme, and that it can often be combined with the WBSO? This means you pay less corporate income tax on the part of the profit that is directly attributable to innovative products, projects and services. For innovative projects there are also schemes such as MIT Feasibility (for mapping technical and economic risks) and MIT R&D Collaboration (specifically for partnerships). Our experts are up to date on all schemes and current developments and are happy to advise you!

The following types of projects qualify for the WBSO:

Development projects:

  • Developing or improving physical products, production processes, or software;
  • Developing prototypes or testing new products or processes;
  • Developing technically new software or substantial improvements to existing software.

Technical-scientific research:

  • Research aimed at acquiring new knowledge;
  • Experimental or theoretical work intended to gain new insights;
  • Research that may lead to new or improved materials, products, processes, systems or services.

Technical feasibility studies:

  • Studies preceding R&D projects to assess the technical feasibility of the project.

Process and software development:

  • Projects aimed at developing or improving production processes or software.

To qualify for the WBSO, applicants must meet the following conditions, among others:

  • Research and development (R&D): The activities must qualify as R&D activities;
  • Entrepreneur for income tax or corporate income tax: The applicant must be an entrepreneur for income tax or corporate income tax purposes in the Netherlands;
  • R&D declaration: The applicant must apply for an R&D declaration (S&O-verklaring) from the RVO. This declaration is proof that the activities are eligible for the WBSO;
  • Time records: The applicant must keep time records showing how much time has been spent on R&D work;
  • Other records: In addition to the time records, records must also be kept of the other costs and expenses that qualify for the WBSO;
  • Minimum R&D hours: A minimum number of R&D hours per year may apply in order to qualify for the scheme;
  • Specific rules for the self-employed: Self-employed persons without staff (zzp’ers) must meet a minimum number of R&D hours to qualify for the WBSO;
  • Starter benefit: Start-up companies may sometimes qualify for an additional benefit;
  • Reporting obligation: After the end of the calendar year, the applicant must report how many R&D hours were actually worked and which costs and expenses were incurred.

The WBSO can be applied for throughout the year. When you submit an application, you can start from the following calendar month. An exception to this rule applies to the last 3 months of the year: for these months, the application must be submitted by 30 September at the latest in order to make use of the WBSO grant. In addition, the WBSO must be applied for again every year if there are ongoing or new projects.

After submitting an application, you may submit an update three times in the calendar year. Additional projects, hours or costs & expenses can then be added to the application.

Thanks to our 25 years of experience, we can optimise your grant process and take it almost entirely off your hands.

What kind of activities can you think of?

  • Assessing whether your project qualifies for a grant;
  • Writing (or reviewing) the grant application and submitting it to the RVO;
  • Acting as contact person towards the RVO;
  • Support in setting up the project records;
  • Preparing you for RVO audits, or even attending them;
  • Taking care of the interim financial reports and final accountability;

A company counts as a starter if, in the preceding five calendar years, it had no staff for at least one year and received an R&D declaration in no more than two calendar years. The starter scheme does not apply if the activities are a continuation of another company. You can use it for a maximum of three years.

What does a grant advisor do?

A grant advisor is an expert who guides companies through the complex process of grant applications and secures the optimal funding for their projects – from choosing suitable schemes through the application to final accountability.

At Ignite we work in a results-oriented way: we only make you a proposal once we are convinced your plan is eligible. You are fully supported throughout the entire process while you focus on your core business – we take over the time-consuming part.

The benefits of our grant advice

Why the WBSO works differently from a grant

If you meet the conditions, you receive the benefit. There is no selection between competing applications.

The benefit runs through the payroll tax you pay, not through corporate income tax.

Because the benefit runs through payroll tax, companies without profit also benefit. The condition is that you have your own staff on the payroll. Hired workers do not count.

What does not count for the WBSO

  • Market research, policy and strategic research.
  • Organisational and administrative activities, even if they relate to R&D.
  • Activities outside the European Union.
  • Maintenance of software and making software suitable for another hardware or software platform.
  • Building or configuring equipment or software for commercial purposes.
  • Implementing or adapting acquired technology, products, processes or software.
  • Setting up and attending courses, training sessions and symposia.
  • Quality control and quality assurance, other than the direct assessment of R&D work carried out.
  • Preparing and carrying out production, and building a pilot plant or prototype with a productive or commercial purpose.
  • Technologically insignificant changes to existing products or processes.
  • This is not an exhaustive list. The distinction between what does and does not count is the most frequently asked question in practice, and we go through it with you project by project.

    How Ignite Group helps you apply for the WBSO

    We determine which work counts as research and development and where routine work begins.

    We write the application along the RVO assessment criteria and submit it on your behalf.

    We make sure time registration and project records are audit-proof from the start.

    We take care of reporting the hours and costs realised within the deadline.

    We prepare you for an announced audit and attend it if you wish.

    Costs and expenses: flat rate or actual

    You calculate with € 10 per R&D hour up to a maximum of 1,800 hours per calendar year, and € 4 per hour above that. With this route you do not need to substantiate the costs and expenses.

    You add the actual R&D costs and expenses to the R&D wage bill. If the actual costs are clearly higher than the flat rate, this route is more attractive. On the other hand, you must keep quotations, order confirmations, invoices and proof of payment.

    equipment or instruments specifically for R&D, materials and raw materials for experiments or test series, parts for building prototypes yourself without a commercial purpose, having such prototypes made by third parties, licences for specific software or ICT resources for your own project, measurements and tests on prototypes, rental of required equipment and costs of parts of buildings used directly and exclusively for R&D.

    depreciation costs, second-hand business assets, costs not directly related to R&D, outsourced R&D, hired labour, training costs, financing costs, attending conferences or trade fairs, subscriptions to trade literature and licences for general business software. Costs that qualify for the MIA or the EIA are also excluded, to prevent the stacking of investment incentives.

    WBSO time records: where it goes wrong in practice

    Hours are recorded per person, per WBSO project and per day. The records must show on which days an employee carried out R&D work within the EU, how many hours that was and on which project. A separate record is kept for each R&D employee. All R&D hours must be entered in the records within ten working days. This is the requirement most often underestimated in practice.

    In addition to the hours, substantive records are required that show per project that the work was actually carried out. For products, production processes and technical-scientific research, this includes reports, calculations, drawings, order confirmations, minutes, quotations, correspondence, photos of prototypes, sketches and test results. For software development, these records look different: code and code versions, proofs of concept, research reports, minutes, screenshots, correspondence, calculations, test and measurement reports, bug tracking systems and version control. A version control system is strongly recommended, as it formally demonstrates that the development has been recorded in a programming language. In both cases: archive chronologically per project and make sure the technical contribution of each R&D employee is recognisable.

    Frequently asked questions about WBSO

    Usually yes. The eight sectors cover our focus areas, not the limits of the funding landscape. What matters is the purpose of your project, not the sector label.

    It finds suitable programmes, assesses the chances, prepares applications and supports the reporting. At Ignite Group that starts with your objective rather than with a list of programmes.

    Usually by whether the outcome is established at the outset. If the solution can be looked up and simply implemented, there is no eligible development. If it has to be tested, discarded and developed anew, there is.

    Usually several apply. What matters is which one is the current bottleneck: capital for growth, development work without matching finance, too narrow an instrument mix, or uncertainty about evidence. We work that out in the first conversation.

    Then several instruments frequently apply, for different projects. We map your whole project portfolio rather than pinning you to one sector.

    At national level these include the WBSO, the MIT R&D scheme, the Innovatiebox, the MIT feasibility studies and the DHI scheme. European instruments such as EUREKA Eurostars are relevant too. Which ones fit your project is something we determine up front.

    That depends on the project, the scale of funding and the model chosen. Our engagement models are explained on a dedicated page, so you know in advance which options exist.
