Choosing Where to Live: the 19 Communes of Brussels

Brussels is not one city you choose to live in — it is 19 separate communes, each with its own mayor, town hall, police zone, income-tax surcharge and personality. Get the choice right and daily life is smooth; get it wrong and you may face a longer commute, a duller weekend or a slightly higher tax bill than a neighbour two streets away. This guide explains what actually differs between communes, with real 2026 numbers, so you can pick well.

What actually changes from commune to commune

Four things vary, in rough order of how much they'll affect your life:

1. Rent — by far the biggest difference. The same flat can cost 40–50% more in Ixelles than in Anderlecht.
2. Vibe, green space and services — how walkable, how family-friendly, how much park, how much nightlife.
3. Language tilt — everywhere is officially bilingual French/Dutch, but the practical mix and the language of your town hall paperwork shifts.
4. The communal income-tax surcharge (4.9–7.5%) — real, but smaller than newcomers fear. Details below.

Two other things you may hear about — the property tax (précompte immobilier / onroerende voorheffing) and various local levies — are mostly paid by property owners, not tenants, so if you're renting they rarely touch you directly.

The commune tax, honestly

Belgium layers a communal surcharge on top of your federal income tax. The crucial point most guides get wrong: it is a percentage of the income tax you already owe — not of your gross salary (FPS Finance). Across Belgium these rates run from roughly 0% to 9%, with a national average around 7%; non-residents pay a flat 7% (PwC).

The rate that applies is set by the commune where you are registered (domiciled) on 1 January of the tax year — not where you work.

Here are the communal income-tax rates for the 19 Brussels communes. Most are the official assessment-year figures published by FPS Finance; a handful of 2026 changes confirmed in the local press are flagged.

Figures marked with ~ are the most recent official assessment-year rates and communes adjust them annually, so treat them as indicative and check your own case. The definitive per-commune list is the FPS Finance table (download PDF).

How much does this really cost you? Because the surcharge is a slice of tax already calculated, the gap between the cheapest (4.9%) and dearest (7.5%) commune usually works out to only a few hundred euros a year for a typical salary — a fraction of a percent of net pay. Do not pick a commune to save tax; pick it for rent, commute and lifestyle, then let the tax fall where it may.

The main expat communes, profiled honestly

Ixelles / Elsene

The default international choice. Central, dense, walkable, with the buzz around Place Flagey, the ponds, Matonge and the student streets near ULB/VUB. Strong café and restaurant scene, easy to live in English. The trade-offs: it's among the most expensive for rent, and it has the region's highest income-tax surcharge (~7.5%). Good for young professionals and couples who want to be in the thick of it.

Etterbeek

Ixelles' quieter, slightly cheaper neighbour, wedged against the EU quarter. Popular with EU-institution staff and families who want central access without Ixelles prices. Leafy in parts (near Parc du Cinquantenaire), practical, mixed French/English. A sensible "can't go wrong" pick.

Saint-Gilles / Sint-Gillis

Younger, more creative, more mixed. Beautiful Art Nouveau housing, a lively bar and market scene around Parvis de Saint-Gilles, and better value than Ixelles for similar centrality. It's denser and grittier in places — some love the energy, some don't. Good for singles, couples and creatives.

Uccle / Ukkel

Green, residential, affluent and calm — the classic family commune in the south. Big houses, gardens, good schools (including the international Lycée Français and proximity to several private schools), and a lower tax rate. The catch: it's spread out, more car-oriented, and the far south is less metro-connected. Best if you want space and quiet over nightlife.

Woluwe-Saint-Lambert & Woluwe-Saint-Pierre

The eastern "Woluwes" are the other big family favourites: lots of green (Woluwe park, Sonian Forest edge), spacious flats and houses, quiet streets and a noticeably stronger Dutch-speaking presence than the west of the city. Woluwe-Saint-Lambert also carries one of the lower income-tax rates. Well-served by metro line 1. Ideal for families and anyone wanting a suburban feel inside the city.

The EU quarter (parts of Brussels City & Etterbeek)

Not a commune in itself but a district straddling a few. Unbeatable for walking to the European Commission, Council or Parliament; modern flats; convenient. The honest downside: it empties out at weekends and in August, and the immediate streets are office-heavy rather than characterful. Great for a short EU posting, less so if you want neighbourhood life.

City centre (Ville de Bruxelles / Stad Brussel)

The City of Brussels commune is large and varied — it covers the historic Pentagon (Grand-Place, Sainte-Catherine, Dansaert), plus Louise, the European quarter fringe, Laeken and Neder-Over-Heembeek. Very central, well-connected, and it now has the lowest income-tax surcharge (4.9%). The centre is lively but can be noisy and touristy; Dansaert and Sainte-Catherine are the most sought-after pockets.

Language: what the FR/NL tilt means for you

Every commune is officially bilingual and you can live in English in most of them. But the practical mix shifts: the west and centre lean more French, while the eastern Woluwes and the outer north lean more Dutch. This matters mainly for two things — the language your town hall (maison communale) deals with you in, and the default language at local schools and crèches. If you plan to send children to Dutch-medium local schooling, a more Dutch-leaning commune helps. For everyday adult life, French is the safer bet almost everywhere. See our French and Dutch in bilingual Brussels guide.

Families: schools, crèches and green space

• Childcare (0–3): overseen by ONE on the French-speaking side and Opgroeien / Kind en Gezin on the Dutch-speaking side. Subsidised places use income-based fees — in 2025 roughly €6.47 to €35.89 per day depending on income and family size. Waiting lists are long: apply from around the third month of pregnancy and register with several crèches (commissioner.brussels). Read the childcare and crèche guide.
• Green space: Uccle, the two Woluwes and Watermael-Boitsfort have the most; Saint-Josse and central Saint-Gilles the least.
• Schools: the European Schools (for EU-institution families) and international schools cluster in the south-east — near Uccle, the Woluwes and Etterbeek — which pushes many EU and international families that way. See schools and the education system.

Rent: how it varies by commune

Rent is where communes truly diverge. As a rough 2026 guide for a one-bedroom flat before charges:

• Priciest: Ixelles, Etterbeek, the Woluwes, Louise/Sablon (~€1,000–1,300+).
• Mid: Saint-Gilles, Forest, Schaerbeek, Jette (~€850–1,100).
• Cheapest: Anderlecht, Molenbeek, parts of Schaerbeek and the outer north (~€700–950).

Always sanity-check an asking rent against the official regional reference-rent tool at loyers.brussels — a rent is presumed excessive if it exceeds the reference by more than 20%. Our cost of living in Brussels and renting an apartment guides go deeper.

Common problems and fixes

• "I chose a commune purely to save tax." Reconsider. The communal surcharge gap is usually a few hundred euros a year; a 15-minute-longer commute or a €150/month higher rent dwarfs it. Optimise for rent and location first.
• "My town hall paperwork is only in French / only in Dutch." Each commune defaults to one working language even though the region is bilingual. If your language skills are weak, pick a commune whose default you're comfortable with, or bring a French/Dutch-speaking friend to appointments.
• "I registered late and got charged the wrong commune's rate." The rate follows your registered address on 1 January. Register your real address promptly after moving to avoid mismatches — see the commune registration guide.
• "The flat's great but there's no metro nearby." Southern Uccle and parts of the outer communes rely on tram or bus. Check the actual door-to-work journey on the STIB app before signing, not just the map.
• "Crèche places are impossible to find." They are, especially mid-year. Apply during pregnancy, list several crèches, and ask each to put your child on the waiting list.

Your next step

Shortlist two or three communes that fit your commute and budget, then run your actual gross salary through the Brussels salary calculator with each commune selected — you'll see for yourself that the tax difference is small, which frees you to choose on rent, transport and lifestyle instead. Then pressure-test a real flat's asking rent on loyers.brussels before you commit.
