Frequently asked questions
What qualifies as R&D for Belgian grants?
Activities involving novelty, uncertainty, systematic approach, and transferable knowledge. Both product and process R&D qualify.
Can I combine R&D grants with the tax credit?
Yes. The 80% wage exemption is cumulative with regional R&D grants. This is one of Belgium's strongest incentives.
How long does an R&D grant application take?
VLAIO: 2–4 months. Innoviris: 3–6 months. Horizon Europe: 5–8 months. The tax credit applies automatically upon qualifying.
Do I need a PhD to claim the R&D tax credit?
No, but the researcher must hold at least a qualifying diploma (master's, certain bachelor's in specific fields). PhD holders qualify automatically.
Are R&D grants available for software development?
Yes, if the software project involves genuine technological uncertainty and novelty beyond routine development.
