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 R&D. Moreover, newly self-employed persons without employees qualify for an additional deduction.

In 2024, the R&D tax credit for self-employed persons is €15,551 and the supplementary R&D tax credit for starters is €7,781. At the end of December 2024, the Ministry of Economic Affairs will announce the R&D tax credit for self-employed persons and starters in 2025. 

Company with employees

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

• the hours spent on R&D, to be reported in the application;
• the R&D hourly wage, calculated on the basis of the citizen service numbers of R&D employees from 2 years ago or a fixed hourly wage of €29;
• costs and expenditures associated with the R&D 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 R&D for the first 1,800 hours;
• €4 per hour spent on R&D for all R&D hours exceeding 1,800.

Benefit percentages and amounts

The amount of wage tax and national insurance contributions you have to pay will be lower (R&D tax rebate). You calculate the amount as follows: ((R&D hours x R&D 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. The WBSO conditions in 2025 will be the same as in 2024. The WBSO parameters are to your benefit changed in 2025.
