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.
