WBSO

The WBSO (Research and Development Tax Credit) provides tax benefits for entrepreneurs engaged in R&D or technical-scientific research. This scheme compensates part of the labour costs associated with research or development projects. Other expenses, such as the purchase of materials, may also be eligible for deduction.

Who is the WBSO for?
The WBSO (Research and Development Tax Credit) provides tax benefits for entrepreneurs engaged in R&D or technical-scientific research. This scheme compensates part of the labour costs associated with research or development projects. Other expenses, such as the purchase of materials, may also be eligible for deduction.

What are the benefits of WBSO?

For withholding agents (such as BVs and NVs):
WBSO reduces payroll taxes related to R&D activities. In 2025, the R&D tax credit (S&O reduction) amounts to:

  • 32% of the first €350,000 of the total R&D wage base

  • 16% of the remaining amount

For taxpayers (such as sole proprietorships, partnerships, and limited partnerships):
Self-employed entrepreneurs who spend at least 500 hours per year on R&D activities are eligible for a fixed R&D deduction. This amount is determined annually. In 2024, the deduction was €15,551.
