WBSO applications for 2026 can be submitted until the end of September.
If you wish to make use of the WBSO this year, or if you have additional projects and hours that you want to claim for 2026, you can do so until the end of September 2026. The WBSO is an R&D (wage) cost subsidy that is offset against payroll tax. The benefit can amount to tens of thousands to hundreds of thousands of euros. The WBSO also opens the way to the Innovation Box.
