WBSO Tax Credit Benefit

Entrepreneur without employees

Businesses that are liable for income tax qualify for a fixed deduction if they spend at least 500 hours per calendar year on WBSO. Moreover, newly self-employed persons without employees qualify for an additional deduction. In 2026, the WBSO tax credit for self-employed persons was €15,979 and the supplementary WBSO tax credit for starters was €7,996. At the end of 2026, the Ministry of Economic Affairs and Climate Policy (EZK) will announce the amounts for the R&D deduction in 2027. Check the website for updates.

Company with employees

The benefit calculation for businesses that are liable for Corporation tax is based on:

• the hours spent on WBSO activities, to be reported in the application;
• the WBSO hourly wage, calculated on the basis of the citizen service numbers of WBSO employees from 2 years ago or a fixed hourly wage. The fixed hourly wage in 2026 was €29. In 2027 it will be increased to €33. This amount will become final once the Senate has approved it;
• costs and expenditures associated with the WBSO project. Each calendar year, you choose between a fixed amount or on the basis of the actual costs and expenditures. The fixed amount for costs and expenditures is:
• €10 per hour spent on WBSO for the first 1,800 hours;
• €4 per hour spent on WBSO for all WBSO hours exceeding 1,800.

Benefit percentages and amounts

The amount of wage tax and national insurance contributions you have to pay will be lower (WBSO tax benefit). You calculate the amount as follows: ((WBSO hours x WBSO hourly wage) + (fixed amount or estimated costs and expenditures)) x first or second tax bracket percentage.

Below you find the benefit percentages and amounts for the WBSO. For you as an applicant, the same conditions and parameters will apply in 2027 as in 2026. The WBSO conditions and WBSO parameters will become final once the Senate has approved them.
