Becoming Self-Employed / Freelance in Belgium (Indépendant)

Belgium calls a freelancer an indépendant (French) or zelfstandige (Dutch), and becoming one is a defined administrative path rather than a vague status. This guide walks through the real steps — business registration, a possible professional card, a social insurance fund, and VAT — with the 2026 figures, so you can start invoicing legally without nasty surprises.

The five things you must sort out

Before your first invoice, you need all of these in place. Skipping one is the classic new-arrival mistake.

1. A professional card (only if you are a non-EU/EEA national and not exempt).
2. Registration in the BCE/KBO (the business register) via a business counter, which gives you your enterprise number.
3. Affiliation with a social insurance fund (caisse d'assurance sociale / sociaal verzekeringsfonds).
4. VAT activation with the FPS Finance (or opt into the small-business exemption).
5. Health cover through a mutuelle / mutualiteit and a separate business bank account.

The good news: one appointment at a business counter (guichet d'entreprises / ondernemingsloket) can trigger the BCE registration, VAT activation and social-fund enrolment together.

Step 1 — Professional card (non-EU nationals only)

If you hold an EU/EEA passport or are Swiss, skip this section. Everyone else generally needs a professional card to be self-employed, with some exceptions (recognised refugees, family members of EEA nationals residing with them, spouses of Belgian citizens, and a few short-stay categories).

In the Brussels-Capital Region the card is handled by Brussels Economy and Employment (Direction de la Migration économique). Your project is judged on three criteria: your right of residence, your ability to meet all self-employed obligations, and the economic usefulness of your activity for Brussels.

• If you are already in Belgium with a valid residence permit (e.g. a model A certificate): apply through an approved business counter.
• If you are still abroad: apply through the Belgian embassy or consulate in your country of residence.

Fees (Brussels, 2026): €140 when you submit the application, and €90 when the card is issued. The card is granted for a maximum of five years (often two years on a first grant) and is tied to your residence rights. Processing a complete file takes roughly three months, so start this early. Verify current details at economy-employment.brussels.

Step 2 — Register in the BCE via a business counter

Every self-employed person must be listed in the Banque-Carrefour des Entreprises (BCE) / Kruispuntbank van Ondernemingen (KBO). You do this through an accredited business counter — private but state-authorised bodies such as Xerius, Acerta, Partena Professional, Securex, UCM or Liantis. They all charge the same legally-set fee and provide identical registration.

What the counter does at your appointment:

• Checks your entrepreneurial capacity where required and any sector permits.
• Registers your activity in the BCE and issues your enterprise number (numéro d'entreprise) — a 10-digit number that is also your VAT number once activated.
• Can activate your VAT and enrol you in a social insurance fund in the same session.

Fee (2026): €111.50 for registration including one establishment unit (this is a legal mission, so no VAT is charged, and it is a deductible business expense). Bring ID, your residence document, your bank details for a business account, and a clear description of your planned activities. Confirm at FPS Economy.

Step 3 — Join a social insurance fund

You must affiliate with a social insurance fund before you actually start your activity. Miss the deadline and you are automatically assigned to the National Auxiliary Fund and may face a fine.

Your fund collects your quarterly social contributions, which buy your self-employed social rights (pension, healthcare reimbursement via your mutuelle, family allowances, sickness/invalidity, and maternity/paternity). Contributions are due each quarter — invoices land at the start of January, April, July and October.

How the contributions work

The rate is 20.5% of your net taxable professional income (a reduced rate applies to the slice of income above roughly €63,300, and no contribution is due above about €93,300). Because a starter has no past income, the fund charges a provisional amount and recalculates it against your real income about three years later — then bills or refunds the difference.

These euro figures (via Securex, management fees included) are approximate and indexed annually — your fund also adds a small management fee (about 3–4.25%). Always confirm the exact number on your own fund's rate sheet. See FPS Economy on the social insurance fund.

Tip: If you expect a slow first year, actively request the primo-starter reduction. If you do nothing, the fund defaults to the higher minimum.

Step 4 — VAT registration

Most self-employed activities are subject to VAT (TVA / btw), whose standard rate is 21%. Your VAT number is your enterprise number prefixed with BE. The business counter or your accountant activates it via the e604A form.

You have a choice:

• Normal VAT regime — you charge VAT, file periodic (usually quarterly) returns, and deduct VAT on your business costs.
• Small-business exemption (franchise / vrijstellingsregeling) — if your annual turnover stays under €25,000 (excl. VAT) you can opt in and then you do not charge VAT or file periodic returns. You still cannot deduct VAT on your purchases, must keep an enterprise number, submit an annual client listing, and declare cessation/changes. Verify at FPS Finance.

A government proposal in April 2026 would raise the exemption ceiling to €30,000, but this needs a legal change to be enacted — treat €25,000 as the figure in force until officially published. Check the FPS Finance page for the current number.

Also note: since 1 January 2026, VAT-registered businesses must send and receive structured electronic invoices (Peppol) for domestic B2B transactions — a PDF by email is no longer compliant for those.

Main activity vs complémentaire — which are you?

Starting complémentaire is the low-risk route: you still register in the BCE and join a fund, but your salaried job carries the main social protection.

Common problems and fixes

• "I invoiced before registering." Stop and register immediately. Invoices without a valid enterprise/VAT number are not compliant; a business counter can usually fix your status quickly, but do it before issuing anything more.
• A big contribution bill three years later. Provisional contributions are recalculated against real income. If your first years go well, voluntarily pay extra into the fund early, or set aside ~20–25% of net income, so the regularisation does not blindside you.
• Bank refuses a "business" account. Some banks are slow with sole-traders. A separate personal account used only for the business is acceptable to open your file, but a proper professional account is cleaner — see our guide on opening a bank account in Belgium.
• Professional card delays. The card can take ~3 months. If you are non-EU, start it before you commit to a lease or clients, because you cannot legally trade without it.
• Not sure you even qualify to work self-employed. Your residence permit must allow self-employment — see the single permit and work-permit rules.

Your concrete next step

Pick one business counter (Xerius, Acerta, Partena, Securex, Liantis or UCM), book a registration appointment, and go in with your ID, residence document, business bank details and a one-line description of your activity. In that single €111.50 session you can walk out with your BCE enterprise number, VAT activated and a social fund chosen — the foundation of being a legal indépendant in Belgium.
