Can I rent out my place on Airbnb in Belgium?
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
- Renting yourself? You first need the owner's written consent, and in a flat the co-owners' association can still rule it out
⚠️ Penalties & fines
In Brussels the administrative fines for an unregistered lodging run from €416 to €41,600, and after the finding in early 2026 that 9 in 10 listings were unregistered, the region is stepping up its checks. In Flanders you get warnings and fines under the Lodging Decree plus removal of your ad. Tax-wise there is no way out: platforms report your revenue via DAC7, so undeclared income leads to back taxes. And if you host as a tenant without your owner's consent, you also risk your lease being dissolved.

❓ 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 to Toerisme Vlaanderen suffices; in Brussels the full registration procedure applies as well.
What do I risk in Brussels without registering?
Administrative fines of €416 to €41,600, plus removal of your listing. And since it emerged in early 2026 that 9 in 10 Brussels listings were unregistered, the region has been checking far more actively than before.
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 dissolving the lease — and in a flat the co-owners' association can forbid it too.
How is my Airbnb income taxed?
Split up: immovable (the rent), movable (the furniture) and possibly miscellaneous (services such as breakfast). Airbnb reports your revenue to the tax office via DAC7, so declaring is not optional.
Must the lodging number really appear in every ad?
In Flanders yes: the lodging number you receive after notifying Toerisme Vlaanderen must appear in every advertisement you place. On top of that you need a fire-safety certificate and insurance for the property.
