How to Apply for a Subsidy in Belgium — Complete Guide
Deadlines, documents, eligibility… This guide walks you step by step through applying for a business subsidy in Belgium.
Check My Eligibility3 things to know before applying
Each subsidy has its own application deadlines — some are rolling, others open via calls for projects.
Required documents vary by agency (VLAIO, Innoviris, SPW…), but a common core exists.
Eligibility depends on your region, sector, company size, and project type.
The 6 universal steps
Check eligibility
Confirm your company meets the subsidy criteria: region, NACE sector, size (SME/large), seniority, and project type. BelGrant automates this check.
Prepare documents
Gather your BCE number, articles of association, annual accounts, project description, and budget forecast. Some subsidies also require support letters or quotes.
Write the project description
Clearly describe the objective, expected results, timeline, and economic impact. Highlight the innovation or added value for the region.
Submit via the official portal
File your application on the agency’s platform (VLAIO e-loket, Innoviris portal, MonEspace SPW). Keep the acknowledgement of receipt.
Follow-up and evaluation
Your file is reviewed by a committee. Timelines range from 4 weeks (vouchers) to 6 months (R&D projects). You may be contacted for additional information.
Justification and reporting
After approval, you must prove fund usage (invoices, activity reports). Non-compliance can lead to partial or full repayment.
Commonly required documents
Mistakes that lead to rejection
Project already started
Most subsidies require that expenses are not incurred before the application.
Incomplete file
A missing document can trigger automatic rejection with no opportunity to correct.
Wrong agency
Applying to another region’s agency (e.g. VLAIO for a Walloon company) invalidates the application.
Vague description
A project without measurable goals, timeline, or detailed budget will be systematically rejected.
