Brussels (Brussels Morning Newspaper)November 09, 2026 – The Brussels-Capital Region is projected to collect approximately six million euros in penalties from unregistered short-term rental properties by the end of 2026. Regional authorities have recovered at least five million euros through an intensive inspection campaign launched by Brussels Taxation to curb non-compliant holiday accommodations and recover unpaid tourist taxes.
Background and Regulatory Framework for Short-Term Accommodations
Since 2016, property owners offering accommodation through digital platforms such as Airbnb within the Brussels-Capital Region have been legally mandated to register their properties with city authorities. In addition to registration requirements, hosts are held liable for tourist taxes. The levy is set at five euros per overnight stay, or four euros if the rental constitutes a room located within a property directly occupied by the lessor.
The regulatory framework also stipulates that operating properties must possess valid fire safety certificates, undergo criminal record checks for hosts, and comply strictly with urban planning regulations. Anaïs Maes, Brussels Councillor for Urban Planning, stated during the initial implementation of the policy that the measures were designed to preserve a balance of property types in the city centre and prevent the capital’s housing market from being hollowed out—mirroring similar regulatory efforts undertaken in major European cities such as Amsterdam and Barcelona.
Legal Precedents and Enforcement Mechanisms
Enforcement capabilities were significantly strengthened following a European Court of Justice decision in 2022, which confirmed that digital platforms like Airbnb are legally obligated to share owner listing information with Brussels Taxation. Despite these regulatory tools aimed at cracking down on undeclared income, safety violations, and unfair competition against the regular hospitality and housing sectors, numerous short-term rental operators continued to lease properties without proper registration or tax declarations.
An investigation conducted by the Inside Airbnb watchdog and analyzed by local media outlet Bruzz revealed widespread non-compliance across the capital. Out of 3,637 active listings identified, 2,788 comprised entire homes, aparthotels, furnished holiday homes, studios, flats, and urban guesthouses. Cross-referencing these active properties with an official list of 546 approved Brussels rentals obtained via a freedom of information request indicated that fewer than 10% of active listings were compliant at the time. Approximately 2,000 owners were subsequently identified as targets for retroactive fines and backdated tourist taxes.
Financial Recovery and Penalty Structures
Over the course of 2025 and 2026, tax authorities recovered at least five million euros through systematic inspection regimes intended to uncover unregistered properties and pursue operators for owed revenues. Non-compliant owners faced standard fines of 1,000 euros per rental unit, alongside assessments for unpaid tourist taxes. In calculating these outstanding sums, tax authorities applied a baseline assumption that properties had been rented out continuously throughout the entire year, placing the burden of proof on owners to demonstrate otherwise.
Budget documents published by Bruzz indicate that tax authorities anticipate property owners have either ceased short-term rental activities or brought their operations into compliance with regional tax laws. Concurrently, the regional budget estimates that Brussels will collect approximately 700,000 euros in standard tourist tax revenue moving into 2027.
Upcoming Regulatory Modifications and Platform Policy Shifts
Looking ahead to the upcoming year, modifications to regional short-term rental policies are scheduled to take effect. At the initiative of Brussels Minister-President Boris Dilliès, the regional government decided to ease specific restrictions governing short-term rentals. Beginning January 1, 2027, rental accommodations situated within a primary residence will no longer require an urban planning certificate. Furthermore, procedures related to safety compliance will be streamlined, and mandatory written approval from co-owners’ associations will be eliminated to reduce administrative paperwork.
Regional officials emphasized that these forthcoming regulatory adjustments do not constitute a complete reprieve for property owners. Properties must still be correctly registered as commercial short-term rentals and will remain subject to all applicable tourist taxes.
Separately, operational policies implemented directly by Airbnb rather than municipal authorities entered into effect, altering checkout requirements for guests. Under the updated platform guidelines, guests cannot be obliged to perform onerous or time-consuming cleaning and tidying chores at the conclusion of their stay.
