This new obligation was approved on December 22nd 2025 by Spain's Ministry of Housing and Urban Agenda in Order VAU/1560/2025.
It has to do with the Single Registry of Leases and the Digital Single Window for Leases (Ventanilla Única Digital de Arrendamientos), a measure introduced earlier in 2025 which makes it compulsory for owners of properties being rented out short-term to register their properties with the Spanish government.
The obligation applies to any rental that isn't long-term (so rentals under than 365 days), meaning that landlords of all short-term, seasonal rentals, tourist accommodation and temporary room rentals must have completed the registration.

Owners had until July 1st 2025 to register their property or face the consequence of having them declared illegal and forcibly removed from platforms like Airbnb.
Registration gives the owner a code in which they must have in order to legally list their property on rental websites.
According to the latest official figures, 299,754 properties in Spain have already obtained their Unique Rental Registration Number, while another 16,581 have a provisional code.
Now, all landlords who registered on the platform and provide short-term accommodation rental services through online platforms must submit a new information form for each unit rented during the previous year. This includes apartments, houses, villas, rooms or even boats.

The first of these new forms must be completed this February 2026 and include information such as purpose of the rental, the number of guests and the check-in and check-out dates.
Essentially it allows the Treasury to link each transaction to a specific accommodation.
It you didn’t rent your accommodation out for certain periods or at all, this also must also be indicated.
Filing the form will be mandatory for all who registered on this system and provide tourist or short-term accommodation or rent out rooms.
It can be submitted in person or electronically via the website of the College of Registrars.
From now on, this form must be completed each February and will apply to the previous year.
The deadline to submit the declaration form this year is March 2nd 2026, as February 28th is not a working day.
Currently, one in five tourist or short-stay rental properties haven’t registered and don’t have a mandatory code to be able to list their property.
A total 84,250 applications have also been revoked. This means 21 out of every 100 applications submitted so far (400,362) have been rejected.
By province, Málaga leads the way with over 36,000 properties registered another 10,327 revoked. This is followed closely by Alicante with 35,916 registered and 8,309 revoked, and Barcelona with 30,092 successful applications and 6,709 denied.
Las Palmas de Gran Canaria has 20,962, which is even more than Madrid with 18,899 authorised units.
Santa Cruz de Tenerife is next with 17,693 and the Balearic Islands have 16,672.
The most likely cause for rejection is that the property doesn’t have a tourist licence or that the neighbourhood association hasn’t given the go-head yet for a tourist rental in their building.
Remember, registration with Digital Single Window does not mean you can legally rent out your property, you must apply for a tourist licence first. It’s merely a list of those that already have licences, as well as short term rentals and rooms.
