Spotlight on the Partial Withholding Tax ExemptionThe challenge of innovation plays a key role in the growth of a modern, knowledge-based economy. The Belgian Government supports Research and Development (R&D) and innovation at both the federal and regional levels using R&D tax incentives to support these activities.

Partial Exemption of Withholding Tax

Companies can benefit from a partial exemption of 80% of withholding tax paid on the wages of scientific researchers. The definition of R&D is in line with the OECD Frascati Manual and encompasses fundamental research, industrial research and experimental development. Qualifying companies also include companies that have partnership agreements with specific European institutions and Young Innovative Companies. Claiming the withholding tax exemption requires pre-approval from the Federal Science Department. New R&D projects have to be registered by a notification procedure.
