Working in Brussels

You're going to start working in Brussels soon? Brussels is a welcoming and international location, but to fully enjoy your time working in Brussels, you need detailed info on the city. We’re glad to help! InterNations gives you know-how on work permits, taxes, healthcare, and social security for expats.

As an expat working in Brussels, you will be part of an international community. At least 30% of the inhabitants are foreign residents. The reason why so many foreigners are currently living and working in Brussels is mainly the city’s status as a center for international politics.

Many other enterprises in the city’s service-oriented economy directly or indirectly depend on the presence of so many foreign politicians, diplomats, and administrative staff working in Brussels. However, multi-national companies with their regional or global headquarters in Brussels also provide jobs for foreign nationals.

International Organizations in Brussels

The largest international organizations by numbers of employees working in Brussels or its environs are, without any doubt, the EU and the NATO (the latter based south of Brussels in Mons). The main EU institutions which have their staff working in Brussels are the European Commission and the European Council. Based in the European Quarter in the east of the city, the Commission alone is said to claim a quarter of the city’s total office space for its employees.

Other large international organizations located in Brussels include, for instance, the World Customs Organization and Eurocontrol. In addition to (and because of) all these inter-governmental organizations and NGOs, there are several hundred lobbying consultancies working in Brussels and, allegedly, more journalists and ambassadors than in Washington D.C. There’s also a small but significant secondary sector industry: Brussels’ breweries are not only world-famous, but they also provide employment for quite a few people.


As a foreigner working in Brussels, paying income tax in Belgium depends on your residency status. You may work there without qualifying as a Belgian resident: In this case, you will only be taxed on that part of your income which you receive from Belgian sources. However, if you are registered in Brussels and physically present more than 183 days per year, or if your asset management is working in Brussels (even if the assets are elsewhere), you will be classified as a Belgian resident for tax purposes.

Expats working in Brussels may be entitled to a tax-free allowance to make up for extra expenses commonly associated with expatriate life, such as travel and relocation costs, housing and school fees, provided these are not covered by the employer. You should contact the tax authorities to find out whether you qualify. The allowance is capped at roughly € 11,000 per year, or around € 30,000 in exceptional cases, e.g. for people working in Brussels who incur excessive travel costs due to their profession.

If you are classified as a Belgian resident, you have to file a tax return at the end of every financial year (same as calendar year). This can be done online via the FPS Finance. The tax authorities of your community will inform you whether you are liable to pay income tax as a foreigner working in Brussels.
