Airbnb Regulation in Brussels: The Complete 2025-2026 Guide
Updated 4 August 2026 — covers the 2026 tax-regularisation campaign and the Ixelles formal notices.
Short-term letting in Brussels is legal under three conditions: mandatory regional registration, the tourist tax (around €3-4/night depending on the municipality) and, for a primary residence, the capped number of rental nights. In 2026 the Region tightened enforcement: about 5,000 Airbnb files targeted by a tax-regularisation campaign (~€13M claimed), some twenty formal notices sent by Ixelles to the main management companies in April 2026, and listings down 23% in twelve months. Being compliant has never mattered more — nor been simpler with the right partner.
You want to rent out your property short-term in Brussels, but you're afraid of getting the regulations wrong? Good news: it's legal and clearly regulated. Bad news: the rules are strict and the penalties can be heavy if you ignore them.
This guide covers everything a property owner needs to know to rent out their home in Brussels in full compliance: registration, city tax, safety standards, taxation — we explain it all.
Contents
1. Mandatory registration with the Region
Since 2022, every tourist accommodation located in the Brussels-Capital Region must be registered with Brussels Economy and Employment, whether you rent out a studio 30 nights a year or an entire building year-round.
Good to know: Registration is mandatory for all rentals of 1 to 90 consecutive days, whatever the type of property and the platform used (Airbnb, Booking, Vrbo, Abritel…).
How do you apply?
The process is done online via the MonBEE portal of Brussels Economy and Employment. You will need to provide:
- A completed registration form
- A criminal record extract (for natural persons)
- A town-planning compliance certificate (depending on your situation)
- Proof of residence or registered office
Once approved, you receive a unique registration number that must appear on all your listings. This number is tied to the property, not the owner.
2. The conditions to meet
Town-planning compliance
Depending on the commune and the type of property, a town-planning compliance certificate may be required. For primary residences rented out occasionally, it is generally not required. For properties dedicated to tourist rental, check with your commune.
Safety and equipment standards
Your accommodation must meet basic safety standards:
- Smoke detector mandatory in all common areas and bedrooms
- Fire extinguisher accessible and up to date
- Electrical installation up to code (sockets and the electrical panel must be in good condition)
- Emergency exit clear and signposted
- Baby cot meeting standards if you provide one
Insurance
Your standard home insurance does not always cover short-term rental. Check with your insurer and take out a suitable insurance extension. Airbnb offers AirCover protection of up to 1 million dollars, but it does not replace standard liability insurance.
3. The tourist tax (city tax)
Since 2023, the Brussels-Capital Region has imposed a flat-rate tourist tax on tourist accommodation. It amounts to €4 per night per traveller (2025 amount, subject to indexation).
This tax is collected by the platforms (Airbnb, Booking) and remitted automatically to the Region. You have nothing to do if you go through them — just check that the option is enabled in your dashboard.
Good to know: Airbnb has been collecting and remitting the Brussels city tax automatically since 2023. If you rent through a platform that doesn't, you must declare it yourself.
4. The risks of non-compliance
The Brussels Region has significantly stepped up inspections in recent years. The risks are real:
| Offence | Penalty |
|---|---|
| No registration | Fine of up to €10,000 |
| Registration number missing from listings | Formal notice + possible fine |
| Failure to declare the city tax | Regularisation + penalties |
| Renting without suitable insurance | Financial risk in the event of a claim |
| Breach of safety standards | Fine + rental ban |
Beyond the fines, Airbnb is required to remove the listings of unregistered accommodation at the Region's request. Not being compliant means risking your income stopping overnight.
5. Taxation: VAT and tax filing
VAT
Short-term rentals (less than 3 months) with para-hotel services (cleaning, linen, check-in) are subject to 6% VAT in Belgium. Rentals without services may be exempt. In practice, if you work with a concierge service like Sabimmo, the concierge service handles the invoicing and the VAT.
Tax filing
Rental income must be declared. Airbnb and Booking automatically report your income to the FPS Finance. Two possible regimes:
- Movable income (unfurnished rental): property withholding tax + personal income tax
- Professional income (furnished rental with services): VAT + corporate or personal income tax
Consult a tax adviser to determine your exact situation — every case is different.
