How to Register a Company in Brussels: The 2026 Guide

If you’re planning to register a company in Brussels, you are choosing the political capital of the European Union, and the process is procedural rather than complicated once you know the order of steps. Brussels-Capital Region straddles Belgium’s two language communities, so paperwork runs in French, Dutch or a mix of both, but every founder goes through the same national system: a notary, the Crossroads Bank for Enterprises, and the tax authorities. This guide covers the legal-form choice, the notary and business-court filing, the 2026 corporate tax rules, realistic costs and timelines, and the VAT, UBO and social security registrations that catch people out. This is general information, not legal or tax advice, so confirm your own situation with a licensed professional before you sign anything.

Why Register a Company in Brussels

Brussels hosts the European Commission, the European Parliament and hundreds of international organisations, which pulls in a concentration of bilingual lawyers, accountants and corporate service firms few other Belgian cities can match. If you plan to register a company in Brussels rather than Antwerp or Ghent, that density of professional support, plus direct EU access and a multilingual talent pool, is usually why.

The Brussels-Capital Region also runs a free business support service, hub.brussels, still widely known as 1819. Advisers answer first-line questions on legal form, subsidies and permits at no cost. The Infopoint is at 110 Chaussee de Charleroi, 1060 Brussels, phone +32 2 422 00 20, staffed Monday to Friday 9:00 to 13:00 plus Tuesday afternoons. This is a sensible first call before you spend money on a notary.

The Registration Process, Step by Step

Here is the realistic sequence to register a company in Brussels as a private limited company, the SRL/BV, which is what most international founders use.

1. Choose your legal form and write a financial plan. Since 2019 there is no legal minimum capital for an SRL/BV, but you still need a financial plan showing two years of funded activity, usually prepared by an accountant.
2. Sign the incorporation deed with a notary. Only a Belgian civil-law notary can draft and authenticate the deed and articles of association. This cannot be done online yourself.
3. The notary files the deed with the business court. It goes to the registry of the relevant Brussels business court, French or Dutch-speaking depending on your registered office, within 30 days.
4. Register with the Crossroads Bank for Enterprises through an accredited business counter. A business counter confirms your activities, registers your establishment unit, and issues your enterprise number, usually same day or within 24 hours. The official fee is 111.50 euros per establishment unit.
5. File your Ultimate Beneficial Owners. Declare who owns or controls more than 25% of shares or voting rights on the UBO register with FPS Finance, within 30 days of incorporation.
6. Activate your VAT number, and register as an employer if hiring. VAT activation is free online through FPS Finance. If you employ anyone, submit a DIMONA declaration before their first day.

Several accredited business counters operate in Brussels.

2026 Corporate Tax and the SME Reduced Rate

The 2026 numbers matter if you register a company in Brussels, because the headline rate is easy to get wrong from an older guide. Belgium’s standard corporate income tax rate is 25%. Small companies, though, can apply a reduced 20% rate on the first 100,000 euros of taxable profit, with the standard 25% applying above that.

To qualify as a small company, your business generally needs turnover under 9 million euros, fewer than 50 employees, and a balance sheet under 4.5 million euros, with at least half the shares held by individuals. From assessment year 2026, a working director must also draw a minimum annual gross remuneration of 50,000 euros, up from 45,000 euros, to keep the reduced rate. If your figures sit near these thresholds, get an accountant to check before you fix a salary structure.

Costs and Timelines to Budget For

Two very different kinds of spend get lumped together when people budget to register a company in Brussels: fixed government charges and professional fees. Only the first is a fixed number.

Government-side, CBE registration costs 111.50 euros per establishment unit, plus a modest Official Gazette fee. Everything else, the notary’s fee, the accountant’s fee for the financial plan, and any business counter service fee, is a market rate that varies by firm. Budget roughly 1,500 to 2,500 euros total to register a company in Brussels as a straightforward SRL, then get firm quotes, since only the CBE fee is fixed.

VAT, UBO and Social Security: The Registrations After Incorporation

Incorporating is not the end of the paperwork; three further registrations apply once you are trading.

Your VAT number comes from FPS Finance, and the standard rate is 21%. If turnover stays under 25,000 euros, you can use the small business exemption instead of charging VAT, but you still need a VAT number and still file an annual customer listing, so exemption is not the same as no paperwork.

Every director working in the business, and every employee, needs their own social security registration. As a self-employed director you must join a social insurance fund; several organisations that run the business counters, including Xerius, Liantis, Partena and Acerta, also operate as funds. Contributions run at 20.5% of net taxable income, billed quarterly, with a provisional minimum around 890.42 euros per quarter for a starter.

If you are relocating to Brussels yourself, budget for the practical side too. Private cover such as ektatraveling.com can bridge the gap before Belgian coverage is active, and a multi-currency account from wise.com or revolut.com usefully complements your business account while a Belgian IBAN is set up. Since Brussels runs in French and Dutch, some founders use lingoda.com or italki.com to get functional fast enough for a notary call or a tax office letter.

Frequently Asked Questions

How long does it take to register a company in Brussels?

With documents ready, the notary deed and business-court filing take about one to two weeks, and CBE registration adds same-day to 24 hours. A business bank account is usually the slowest step, often another one to three weeks.

What is the corporate tax rate in Brussels in 2026?

Belgium’s standard corporate income tax rate is 25% nationwide, including Brussels. Small companies can apply a reduced 20% rate on the first 100,000 euros of profit if they meet the size and director-remuneration conditions.

Do I need a notary to register a company in Brussels?

Yes, for an SRL/BV, SA or SC. Only a Belgian civil-law notary can draft and authenticate the incorporation deed and articles of association, so a notary is mandatory, not an optional extra.

How much does it cost to register a company in Brussels?

The official CBE fee is 111.50 euros per establishment unit. Add notary, financial plan and business counter service fees, and total costs typically land around 1,500 to 2,500 euros for a straightforward SRL.

When do I need to register for VAT?

You can activate a VAT number as soon as you incorporate, and you need one even under the 25,000-euro small business exemption threshold, since that scheme exempts you from charging VAT, not from holding a number.
