Spain tried a single national register for short-term rentals, then the Supreme Court scrapped it in May 2026. Regional licences still decide whether you can legally let, a 10% VAT on tourist rentals starts on 1 December 2026, and Barcelona has provisionally approved a property tax surcharge of up to 150% for tourist flats (final plenary vote pending). The compliance bill keeps growing, which is exactly why the commission you pay the platforms deserves a second look.
Royal Decree 1312/2024 created the Registro Único de Arrendamientos, a single national register for short-term rentals. From 1 July 2025, every property offered through a covered online platform had to display an official registration number. Enforcement was real: Spain's consumer ministry reported that Airbnb had removed around 65,000 listings identified as lacking the required licence.
Then came the reversal. In a judgment of 21 May 2026, published in the BOE on 26 June 2026, the Supreme Court annulled the register provisions of the decree. The national registration number is no longer required. What survived: the Digital Single Window, the platforms' duty to send data to the authorities, and EU Regulation 2024/1028, in force since 20 May 2026.
The lesson for hosts is not that regulation went away. It is that the rules can flip within a year, and the layer that actually decides your case is regional.
Take Valencia as an example. Advertising a tourist flat without its Registro de Turismo number and exact location is an infringement under the regional tourism law. Getting a licence now requires a Certificado de Compatibilidad Urbanística (CCU) from the city council, and under Decree Law 9/2024 tourist licences are no longer indefinite: they must be renewed every five years.
Check your autonomous community's current requirements before you list. The national number is gone; the regional paperwork is not.
The housing decree published on 7 October 2026 (in force 8 October) extends a 10% VAT to short-stay holiday rentals from 1 December 2026. This category of accommodation was previously exempt. The government's published explanation says parliamentary validation is still required, so treat the date as near-certain rather than final and watch for confirmation before you reprice.
Note the geography: mainland Spain and the Balearic Islands fall within Spanish VAT territory; the Canary Islands, Ceuta and Melilla do not. Exclusion from VAT does not mean exclusion from other taxes.
Barcelona's city council economic committee has provisionally approved a property tax surcharge of up to 150% for tourist apartments (final plenary vote pending). Spain had already given municipalities in stressed housing areas the power to add surcharges; Barcelona is now putting it into concrete tax bands. If you hold a tourist flat in the city, this changes the annual holding cost directly.
Since 3 April 2025, a new tourist apartment in a homeowner community needs express prior approval by three-fifths of the owners, reversing the previous default. A general reference to residential use in the statutes is not enough to prohibit them, but an express three-fifths agreement is enough to do so. Communities can also increase common expenses by up to 20% for tourist apartments, with no retroactive effect.
Licence paperwork, five-year renewals, safety upgrades, a 150% tax surcharge in Barcelona, 10% VAT from December: these are fixed costs. You pay them whether the booking came through Booking.com, Airbnb or your own website.
The platform commission is different. It is a variable cost, around 15% on Booking.com, and it is the one you can actually cut. A direct booking website does not remove the compliance burden, but it stops the platforms taking their cut on top of it. Our Booking.com commission guide shows what that cut looks like in pounds per year.
Take a Spanish apartment grossing €30,000 a year through the platforms at an assumed 15% commission.
Platform commission: €4,500 a year, every year, on top of every new tax and surcharge.
That €4,500 is the part of the bill you can do something about.
No. The Supreme Court annulled the national register provisions of Royal Decree 1312/2024 in a judgment of 21 May 2026, published in the BOE on 26 June 2026. The national number is no longer required. Regional and municipal licences still apply.
1 December 2026, under the housing decree published on 7 October 2026. Short-stay holiday rentals were previously exempt. Parliamentary validation is still required, so confirm before repricing.

Since 3 April 2025, a new tourist apartment in a homeowner community needs express prior approval by three-fifths of the owners. Communities may also raise common expenses by up to 20% for tourist apartments.
Yes. The court only annulled the national register provisions. Regional licences remain in force, for example Valencia's Registro de Turismo number, the CCU certificate, and five-year licence renewals.
