Every Belgian company needs a registered address. A virtual office provides a professional business address without the cost of a full office — ideal for startups, remote companies, and international businesses entering Belgium.
Belgian law requires every company to have a registered office address (maatschappelijke zetel/siège social). This address is published in the Belgian Official Gazette, registered with the KBO/BCE, and determines the company's legal jurisdiction and language regime. A virtual office provides this address without renting full office space. For company registration and representative office setup, we assist with address selection.

When a Virtual Office Makes Sense
Startup phase — keep costs low while establishing your business
Remote/distributed teams — no need for physical office space
Holding companies — need an address but minimal operations
Testing the market — before committing to a full office lease
Considerations
Bank account opening — some banks prefer companies with a physical office. A virtual office is generally accepted but may trigger additional KYC questions. See non-resident banking.
Substance requirements — if tax authorities question whether your company has real economic substance in Belgium, a virtual office alone may not suffice. Having employees, directors, and real operations strengthens your position.
Client perception — a prestigious address can enhance credibility; an obviously virtual address may not.
Yes. A virtual office with a physical address is acceptable. PO boxes are not.
€50–€300/month depending on location and services. Basic address: €50–€100. With mail/phone: €100–€200. Premium with meeting rooms: €200–€300.
No. A virtual office, co-working space, or serviced office address is sufficient for company registration.
Yes. Non-resident directors commonly use virtual offices. The address satisfies legal requirements but substance questions may arise.
A formal contract allowing your company to use the provider's address as registered office. Required by Belgian law. Must be available for inspection.
Typical virtual office packages include: registered business address (for CBE/VAT), mail receiving and forwarding, phone answering service, use of meeting rooms (by the hour/day), access to co-working space, and a prestigious business address for marketing materials. Some providers also offer company registration assistance and domiciliation agreements.
Yes. Changing the registered office requires: a board decision (or general assembly for significant changes), amendment of the articles of association via notarial deed (if changing regions), CBE update, publication in the Moniteur Belge, and notification to banks/authorities. Changing within the same region is simpler than cross-region moves.
Not all. Some co-working spaces offer desk/meeting room access but do not provide formal domiciliation services. For company registration, you need a provider that offers a domiciliation agreement (domicilieringsovereenkomst). Verify that the provider is authorised and that their address is accepted by the commercial court and enterprise counter.
Yes, if you own or rent the property. Using your home address is the cheapest option (no virtual office fee) and is perfectly legal. However: the address becomes public (published in Moniteur Belge and KBO/BCE database), you may need landlord permission if renting, and home-based businesses may face zoning restrictions in some communes.
A virtual office provides an address and mail services without physical workspace. A serviced office provides a furnished, ready-to-use office space with receptionist, meeting rooms, and shared facilities — typically on flexible terms (monthly contracts). Serviced offices cost more (€300–€1,500/month) but include everything needed for a physical presence.
Yes, but some traditional banks may ask additional questions about your physical presence and business substance. Having a domiciliation agreement helps. Fintech banks (Wise, Revolut) generally accept virtual office addresses without issue. For traditional banks (KBC, BNP Paribas), a professional introduction from your accountant or lawyer helps.
