Moving to Belgium: A First-Steps Guide for Expats

Belgium has a public relations problem. It is described as complicated, over-administered and politically baffling, all of which is true, and it is also one of the more comfortable countries in Europe to actually live in - large affordable houses, superb food, excellent healthcare, and a location that puts London, Paris, Amsterdam and Cologne all within a couple of hours by train.

The complication is real and mostly front-loaded. Get through the first three months and it settles down into something rather pleasant.

The language map comes first

Before anything practical: Belgium is federal, and its regions have language regimes that determine how the state deals with you.

Flanders operates in Dutch. Wallonia operates in French. Brussels is officially bilingual Dutch-French. A small German-speaking community exists in the east.

This is not decorative. Your commune will conduct business in its official language, official documents arrive in that language, and school systems are organised along the same lines. Choosing where to live is therefore also choosing which language your administrative life happens in - a decision people make accidentally and then live with for years.

Brussels is where most international arrivals land, partly because of the EU institutions and the enormous international sector around them, and it is the most forgiving in English terms.

The right to stay, and the police visit

EU, EEA and Swiss citizens may live and work in Belgium, registering with their commune and receiving a residence document.

Non-EU nationals need authorisation before arriving in most cases - a work permit or single permit combining work and residence, arranged with an employer, or routes for study, family reunification, EU Blue Card holders and the self-employed with a professional card. The Belgium visa section covers the current routes.

The distinctively Belgian step comes next. You declare your arrival at the commune of your address, and then a local police officer visits to verify that you actually live there. This is completely routine and catches every newcomer by surprise. Be reachable, make sure your name is on the letterbox - genuinely, this is what they check - and be at home or arrange a time. Only after that verification are you entered on the population register and issued your residence card and national number.

Everything else queues behind that number, which is the general pattern described in registering your address abroad.

Healthcare, which is excellent

Belgium’s system is a social insurance model and it consistently ranks among the best in Europe for access and waiting times. You can generally see a specialist quickly and without a referral, though going through a GP gives you better reimbursement.

The mechanism is unusual and worth understanding. You must join a mutualité (French) or ziekenfonds (Dutch) - a health insurance fund - which administers the national scheme for you. There are several, they are broadly similar, and choosing one is a normal early errand. You typically pay the doctor and are reimbursed a large proportion, so most people also take supplementary cover from the same fund for hospital costs and the remainder.

Details in the Belgium healthcare section, and the general logic of reimbursement systems in public versus private healthcare.

Money and tax

Here is the honest part: Belgium has one of the widest gaps between gross and net employment income in Europe. Income tax is progressive and reaches its top rate at a relatively modest income by international standards, social contributions are significant, and there are communal surcharges on top.

Against that, the services are real and there are structural compensations - the treizième mois thirteenth-month payment is common, meal vouchers and other benefits in kind are a normal part of packages, and company cars have historically been a large feature of Belgian compensation for tax reasons.

If you are comparing an offer here against one elsewhere, do the arithmetic on net rather than gross, which is exactly the argument in understanding your first payslip. Structure is in the Belgium tax section and the residence principle in tax residency explained.

There is a special regime for certain inbound taxpayers and researchers recruited from abroad, with specific conditions that have been revised - worth asking your employer about rather than assuming.

Housing, which is the good news

After the Netherlands, Belgian housing feels generous. You get more space for less money, houses rather than flats are common, and the market is not the scramble it is across the northern border. This is precisely why a substantial number of people working in the Netherlands or Luxembourg live on the Belgian side of the border.

Points to know: registering the lease is a legal requirement and matters for your rights; deposits are typically placed in a blocked account in your name; and an inventory - état des lieux / plaatsbeschrijving - drawn up at entry is standard and is what decides deposit disputes at the end. Take it seriously, in the spirit of renting your first apartment abroad.

Older Belgian housing stock can be poorly insulated, and energy costs have been a live issue, so ask about the energy rating rather than only the rent.

Settling in

The international community in Brussels is enormous and easy to join, which makes for a soft landing and the familiar risk of never leaving it. Belgians outside that world can take longer to befriend, and doing anything in the local language of your region shifts things noticeably - see learning the local language fast.

Practical pleasures: the food is genuinely excellent and unpretentious, the train network makes weekend travel absurdly easy, and the country is small enough that nothing is far. Practical irritations: the paperwork, the weather, and a political structure that produces institutional oddities you will eventually find funny.

Schools and the language decision

Belgian education is free, generally good, and organised by language community rather than nationally - which means choosing a school is inseparable from the language question. In Flanders your child will be schooled in Dutch, in Wallonia in French, and in Brussels you choose between Dutch-language and French-language systems, with different admission processes for each.

That choice is more consequential than it looks. It shapes which friendships form, which universities are natural next steps, and how the family integrates locally. Brussels admission to popular schools operates through registration systems where timing genuinely matters, so research the process for your commune well before you need it.

There is also a substantial international school sector, driven by the EU institutions and the diplomatic community, along with the European Schools serving EU staff. These are excellent and expensive, and they are the standard choice for shorter postings.

For a family staying more than a couple of years, local schooling is usually the better long-term decision and the harder first year. The trade-offs are set out in international versus local schools, and the wider family logistics in moving abroad with kids.

What catches people out

Not knowing about the police visit and missing it. Choosing a commune without realising it fixes the language of your administrative life. Comparing a Belgian gross salary with a foreign one. And underestimating heating bills in an old, uninsulated house.

For neighbours, moving to the Netherlands is the direct comparison - easier admin, much harder housing - and moving to Luxembourg and moving to France complete the picture for anyone weighing the region.

Region-level detail, current permit routes and cost breakdowns are in the Belgium country guide and the cost of living section. For commune-specific experiences, the general forum is the place to ask.
