As the de facto capital of the European Union and host to major global institutions, it is also one of the most strategically important business locations in Europe.

This guide covers which major employers are based in Belgium, why the country attracts them, and what you need to know practically as an expat looking to work for one of them.

Why does Belgium attract so many international companies?

Several factors make Belgium one of the most attractive locations in Europe for international companies.

Belgium sits at the geographic heart of Western Europe, sharing borders with France, Germany, the Netherlands, and Luxembourg. Its central position, combined with world-class logistics infrastructure, makes it an ideal base for companies serving the European market. The Port of Antwerp-Bruges is one of the largest ports in the world and a critical gateway for European trade.

Brussels is home to the European Commission, the European Parliament, and the Council of the EU, as well as NATO headquarters. Hosting these powerful institutions has fostered a dense ecosystem of lobbying, consulting, legal, and policy-facing organisations, drawing a large and highly international workforce. Belgium is also an EU member state, which means companies based here have full access to the EU single market.

Belgium has a highly educated, trilingual workforce. Dutch is spoken in Flanders, French in Wallonia, and German in a small eastern region. English is widely used in international business environments, particularly in Brussels and Antwerp. The country also offers a competitive corporate tax environment, including an innovation income deduction for research and development activities, which is particularly attractive to pharmaceutical and technology companies.

What do international companies in Belgium look for?

International companies in Belgium hire across a wide range of levels, from graduate and early-career roles to specialist and senior management positions. The bar is generally high, particularly at multinational headquarters.

Language skills are important. While English is used broadly at international firms, the majority of roles in Belgium require at least one Belgian national language (Dutch or French), depending on the region and company. Brussels roles often ask for bilingual French and English proficiency. Roles in Flemish-based companies frequently require Dutch.

As an EU member state, Belgium applies the EU freedom of movement principles. EU and EEA nationals can work in Belgium without a work permit. Non-EU nationals require a professional card or work permit, depending on their situation. For salaried employees, the employer typically applies for the permit on behalf of the candidate. Large international companies with established HR functions are best placed to support this process. You can verify current rules on the official Belgian immigration and work permit page from the Immigration Office.

Here’s a practical checklist before you apply:

• Relevant degree or professional qualification in your field
• Several years of experience at the appropriate level
• Fluent English (essential for most multinational roles)
• At least one Belgian national language (an advantage for most; required for many)
• Valid right to work in Belgium, or EU/EEA nationality

Working at an international company in Belgium: what to expect

Belgian salaries are competitive by European standards, though lower on average than Switzerland or the UK at the top end. Roles in pharmaceuticals, finance, and technology tend to attract the strongest compensation packages. You can use our guide to the minimum wage and average salary in Belgium to benchmark pay in your sector. The cost of living in Belgium is moderate by Western European standards, with Brussels being the most expensive city, though still affordable compared to cities like London or Zurich.

Working hours are typically 38 to 40 hours per week, Monday to Friday. Belgian employment law provides strong employee protections, including a minimum of 20 days paid annual leave per year (with many employers offering more), parental leave rights, and statutory notice periods. Employment contracts in Belgium are generally well-structured and transparent.

Social security contributions in Belgium are compulsory for both employees and employers. These fund healthcare, unemployment insurance, pensions, and family allowances. Health insurance is organised through a mutual insurance fund (mutualité or ziekenfonds), which applies from the moment you stay in Belgium for more than three months. Many large international employers offer complementary group insurance and pension schemes.

One common financial consideration for expats is managing money across borders. If you receive your salary in euros but have financial commitments in another currency, such as a mortgage, family support, or savings in the UK, US, or elsewhere, understanding the cost of converting and sending money abroad is worth doing early.

Manage your international finances in Belgium with Wise

Earning in euros while maintaining financial ties in another currency is one of the most common challenges for expats working at international companies in Belgium. Many expats keep a bank account in their home country and need to send a regular portion of their salary abroad. When you do this through a bank, the exchange rate applied often includes a mark-up compared to the mid-market rate, the neutral rate you would see on a currency search, which means you receive less than the headline figures suggest.

Wise is a money transfer service that converts and sends money using the real, mid-market exchange rate, with a small, transparent fee shown clearly before you confirm. It supports EUR alongside 40+ other currencies, which makes it a practical option for expats moving earnings between Belgium and the UK, the US, Australia, or other countries.

You can open a Wise account and check the exact fees for your specific currency route on the Wise website before you send.

Frequently asked questions about international companies in Belgium

Which city in Belgium has the most international companies?

Brussels has one of the highest concentrations of international companies, particularly in finance, professional services, technology, and EU-facing organisations. It is also home to the European Commission, European Parliament, and NATO, creating a unique ecosystem for internationally mobile professionals. Antwerp is the second major hub, especially for chemicals, logistics, and the port sector. Leuven is home to AB InBev and a strong biotech and academic cluster, while Ghent is a growing centre for life sciences and food technology.

Do international companies in Belgium work in English?

Most large international companies in Belgium use English as their primary working language for internal communications, management, and cross-border roles. However, language requirements in Belgium are more complex than in many other countries, because the country is divided into distinct linguistic regions. Companies based in Flanders may expect Dutch alongside English. Brussels-based roles often require French, and sometimes both French and Dutch. If you are looking for companies in Belgium that use English as the main day-to-day language, Brussels-based multinationals and EU institutions are your strongest starting point.

What is the biggest company headquartered in Belgium?

By revenue and global brand recognition, AB InBev, headquartered in Leuven, is Belgium’s most internationally recognisable company. It is the world’s largest brewer, with more than 150,000 employees worldwide, and is the only Belgian company currently ranked on the Fortune Global 500. In chemicals, Solvay is one of Belgium’s largest and most global companies. In pharmaceuticals, UCB has a strong international profile, particularly in neurology and immunology.

Can expats work in Belgium without an EU/EEA passport?

Yes, but the process requires employer support. EU and EEA nationals can work freely in Belgium under the EU freedom of movement. Non-EU nationals, including British, American, and Australian citizens, need a work permit, typically obtained by their employer on their behalf. Large international companies with dedicated HR teams are generally the best-placed employers to manage this process. Always verify the latest requirements with the Belgian Immigration Office before applying.
