🛏️ Can I rent out my place on Airbnb in Belgium?

With conditions

Quick answer

Yes — but register first, because enforcement is ramping up fast. Tourist rentals are regional. In Flanders you notify your lodging to Toerisme Vlaanderen (Lodging Decree): you get a lodging number that must appear in every ad, backed by a fire-safety certificate and insurance. In Brussels it's heavier: a genuine registration with Brussels Economy and Employment requiring a file of about eight documents (urban-planning conformity included), sometimes the co-owners' consent — fines run €416 to €41,600, and after the finding in early 2026 that 9 in 10 listings were unregistered, the region is stepping up checks. Wallonia asks for a declaration under its tourism code. Everywhere on top: declare the income to the tax office (platforms report via DAC7), and tenants first need the owner's written consent.

📋 The rules

Flanders: notify Toerisme Vlaanderen + lodging number in every ad + fire-safety certificate
Brussels: registration (±8 documents, planning) — fines €416–41,600
Wallonia: declaration under the Walloon tourism code
Income must be declared — platforms report to the tax office (DAC7)
Tenant? First the owner's written consent; apartments: check the co-owners' association

🔓 Exceptions

Occasionally hosting a room while present: same registration duty, often a lighter file
Cities can restrict further (quotas, neighbourhood rules) — check local regulations before investing

⚠️ Penalties & fines

Brussels: administrative fines of €416 to €41,600 for unregistered lodgings; Flanders: warnings and fines under the Lodging Decree plus ad removal. Tax-wise: undeclared income triggers back taxes — platform data makes it traceable.

❓ Frequently asked

I only rent a room occasionally. Must I register?

Yes — even occasional tourist rental falls under the regional rules; in Flanders the (free) notification suffices, in Brussels the registration procedure applies too.

What do I risk in Brussels without registering?

Administrative fines of €416 to €41,600 and delisting — and since the finding that 9 in 10 listings are illegal, the region checks more actively.

As a tenant, can I list my flat on Airbnb?

Only with your landlord's written consent — subletting without it is breach of contract and a classic ground for lease termination.

How is my Airbnb income taxed?

Split up: immovable (rent), movable (furniture) and possibly miscellaneous (services like breakfast) — and Airbnb reports your revenue to the tax office via DAC7, so declaring isn't optional.
