Self-employed in Brussels: a unique context
The Brussels-Capital Region concentrates an unmatched density of economic activities in Belgium: company headquarters, European institutions, tertiary sector, startup ecosystem, freelancers in digital, consulting and creation. For a self-employed person, it's a huge market — but also the most competitive and expensive in the country.
On taxation, the social status and federal income tax work exactly as in other regions. What changes in Brussels:
hub.brussels and 1819: your one-stop shop
The regional agency hub.brussels is the public body supporting entrepreneurs and self-employed people in the Brussels-Capital Region. It brings together former structures (Atrium, Brussels Invest & Export, Impulse) into a single entry point.
Concretely, it offers:
Free number (from Belgium) for any business question. You can ask a legal, tax or administrative question, or request an orientation appointment. Your first reflex when in doubt.
Free sessions with specialized advisors based on your sector (commerce, creative, tech, social economy). Ideal to frame your financial plan before launching.
Sector accelerators (Greenbizz for circular economy, Fashion & Design Platform, etc.) for higher-potential projects.
Access to shared spaces at preferential rates, more than 50 labelled coworking spaces in the Brussels Region.
Financial aids specific to Brussels
The Brussels-Capital Region offers several direct or indirect aid levers, the most useful for self-employed in 2026:
The Tremplin Indépendant grant
This grant targets people starting a self-employed activity after a period of inactivity (unemployment, social welfare, end of studies). It takes the form of degressive financial support over 6 months and free coaching. Payment is conditional on effective registration with the BCE/KBO and INASTI.
The "First hire" subsidy
If your self-employed activity grows to the point of needing to hire your first employee, certain Brussels regional aids can reduce the net cost of this employment during the first months. Specific information via Actiris and hub.brussels based on your profile and the future employee's.
Brussels enterprise vouchers
Several mechanisms for funding external services (consulting, training, market study, digital support) with partial regional coverage. Particularly useful to structure your activity at start.
Finance.brussels
The regional financial arm. Offers microcredits (up to €25,000) and subordinated loans to self-employed and small businesses struggling to obtain classic bank credit. Softer conditions than at the bank, but rigorous evaluation of the financial plan.
Before any grant application, first call 1819. An advisor verifies your eligibility in 10 minutes and saves you building a file that will be refused. Many aids are underused simply because self-employed people don't know they exist.
Steps specific to Brussels
The federal administrative path (BCE/KBO, INASTI, VAT, mutuality) is detailed in the Belgium guide. In Brussels, a few local steps are added depending on your activity.
