Brussels in 5 numbers
The Brussels-Capital Region is the smallest of the three Belgian regions in area but the densest in population. It's also the only officially bilingual territory (French + Dutch) of the country, which is reflected throughout its administration.
Brussels concentrates a disproportionate share of Belgian economic activity: headquarters of European institutions, major companies, tertiary sector, non-profits and international organizations. This strongly influences the cost of living, real estate and the labor market.
Buying in Brussels — real estate taxation
The number one topic for most Brussels residents. Brussels registration duties are the highest of the three regions, but the very generous abatement radically changes the picture for the main residence.
Rate and abatement
The standard rate is 12.5% on the purchase value. But if you buy your first home and establish your main residence there, you benefit from an abatement on the first €200,000. Concretely, on these €200,000, you pay no duties — a maximum saving of €25,000.
For an apartment at €350,000 in Schaerbeek, as main residence and first purchase: you pay 12.5% on €150,000 (= 350,000 − 200,000 abated), i.e. €18,750 in duties. Without the abatement, you would pay €43,750.
Conditions of the abatement
- First purchase (no full ownership of another property)
- Natural person (not a company)
- Establish main residence there within 3 years
- Stay domiciled there for at least 5 years

Energy grants & renovation
2026 is a pivotal year in Brussels. The Region has suspended new Renolution applications pending a system reform. Files submitted before the suspension remain in processing, but no new regional grant is currently accessible.
While waiting for the system overhaul, several levers remain available:
- ECORENO loan via the Housing Fund: very low rate loan (sometimes 0%) for energy renovation of Brussels residents under income conditions
- Specific municipal grants based on your municipality (Etterbeek, Ixelles, Uccle, etc. have their own aids)
- Reduced 6% VAT for renovation works in homes over 10 years old
- Free support via Homegrade for Brussels residents (audit, advice, file preparation help)

Working & starting a business in Brussels
The Brussels ecosystem is one of the densest in Belgium for self-employed and young companies. Several regional one-stop shops centralize information and support.
Looking for a job
Actiris is the regional public employment service in Brussels. It's the equivalent of Le Forem in Wallonia or VDAB in Flanders. You'll find regional job offers, qualifying training (via Bruxelles Formation), employer hiring aids and personalized support for jobseekers.
Becoming self-employed
Several structures help future Brussels self-employed:
- 1819.brussels — the line and platform for info on entrepreneurship in Brussels. First reflex for any question.
- hub.brussels — the regional agency supporting business development (international, financing, advice).
- Tremplin Indépendants via Actiris for jobseekers who want to launch (allowances partially maintained for 6 months).

Family allowances — Famiris
Since regionalization in 2019, family allowances are managed by the regions. In Brussels, the main body is Famiris (formerly Iriscare), but you can also choose an accredited private fund like Infino, Kidslife or Parentia.
The base amount and supplements depend on household composition, income and the child's situation. The scales are specific to Brussels and differ slightly from those of Wallonia (FAMIWAL) or Flanders (Groeipakket).
Regional and municipal taxes
Beyond the federal personal income tax, you also pay regional and municipal taxes in Brussels:
- Property tax — based on cadastral income, managed by Brussels Fiscalité. Municipal surcharges vary widely depending on municipality.
- Autonomous regional tax (the "Brussels flat-rate tax") on certain categories, especially offices.
- Specific municipal taxes (waste collection, second homes, vacant buildings, etc.) — consult your municipality's site.
Municipal surcharges can double your property tax bill from one municipality to another. Always look at the municipality before the neighborhood.
Mobility & LEZ
Brussels has a strict low-emission zone (LEZ) covering the entire Region. Older petrol or diesel vehicles are progressively banned according to a published schedule. By 2026, Euro 5 and older diesels are excluded, and conditions tighten each year.
On the mobility side, STIB (metro/tram/bus), SNCB (train), Villo! (shared bikes) and Cambio (car sharing) manage an integrated network via the MaaS platform Floya.
3 pitfalls to avoid in Brussels
1. Underestimating municipal surcharges
Two identical homes five minutes apart can have annual property taxes differing by more than 30%, simply because they're in two different Brussels municipalities. Always look at the municipality before the neighborhood.
2. Administrative bilingualism
All Brussels public services must operate in French and Dutch. Choosing the wrong language at registration can complicate your administrative follow-up (Actiris vs VDAB Brussel, mutuality, school...). When in doubt: choose the language you're most comfortable with for important procedures.
3. Renolution frozen in 2026
If you plan an energy renovation this year, don't count on regional grants for now. Switch to the ECORENO loan and municipal grants, and keep an eye on the announcement of the new version of the system.
