Spain Tourist Rental Registry Annulled: What Owners Need to Know

If you bought a flat in Valencia or Málaga to rent to tourists, the rulebook just shifted under you. On May 21, 2026, Spain's Supreme Court struck down the national registry that holiday let owners had been told was mandatory, and with it the registration number that platforms were demanding before they would list a property.

Spain's Supreme Court annulled the national Registro Único de Arrendamientos and its NRUA registration number in ruling 620/2026, dated May 21, 2026. The court found that central government lacked the constitutional competence to run a national registry that overlapped existing regional ones. Since that date, owners no longer need the NRUA to advertise a short term rental on digital platforms.

What did the Supreme Court actually annul?

Only the national registry, not the whole system. The Tribunal Supremo partly upheld a challenge brought by the Generalitat Valenciana, ruling that the State invaded the powers of the comunidades autónomas by creating a national registry on top of theirs. The judges annulled the parts of Royal Decree 1312/2024 that set up the Registro Único de Arrendamientos and the NRUA number.

What the court left standing matters just as much. The Ventanilla Única Digital de Arrendamientos, the duty on platforms such as Airbnb and Booking to transmit data, and the transfer of data for statistical purposes all survive, according to the Ministerio de Vivienda y Agenda Urbana.

Do you still need a registration number to rent short term?

Not the national one. As of May 21, 2026, the NRUA is no longer required, and no report tied to it is needed to list on a platform. That is a real change from the regime that had been mandatory since July 1, 2025 under Royal Decree 1312/2024.

This does not mean holiday lets are unregulated. It means the layer that applies is regional rather than national.

Which rules still apply to holiday lets?

Several, and they are the ones that already carried real penalties:

• Regional tourist registries. Each comunidad autónoma keeps its own licence or registration regime, and these are unaffected by the ruling.
• The registro de viajeros. The duty to report guests to the authorities continues exactly as before.
• Tax control. Income from short term lets stays fully taxable, and reporting obligations are unchanged.

In short, the national number disappeared, but the regional licence, the guest reporting, and the tax bill did not.

What this means before you buy a rental property in Spain

Buy on the local rules, not the headline. Before you commit to a flat you intend to let, check the relevant comunidad autónoma's tourist licence regime and whether the building's comunidad de propietarios permits short term letting at all, because many now restrict it.
