Renting out property in Spain looks different in 2026. A Supreme Court ruling has changed how short-term lets are registered, a new annual tax return now applies to holiday lettings, and rent caps continue to spread across stressed market zones. This guide sets out what changed, who it affects and what landlords should do next.
Long-Term Rentals: What Applies in 2026
The framework still comes from the 2023 housing law, but several parts only started to bite recently.
Rent Increases Follow a State Index
Annual rent updates no longer track the consumer price index. They follow the state reference index (IRAV), which is designed to keep increases below general inflation. Any clause in a new contract that ignores it will not hold up.
Landlords Pay the Agency Fees
Estate agency commission and the cost of arranging the contract now fall on the owner, not the tenant. The same applies to rent default insurance taken out by the landlord.
Stressed Market Zones Keep Growing
Regions can ask the state to declare a zona de mercado residencial tensionado. Inside those areas, rents on new contracts are capped by reference to the previous contract or the official price index. By April 2026 roughly 307 municipalities had been declared, concentrated in Catalonia, the Basque Country, Navarre and Galicia. Most of Spain remains outside the system, so the first step is always to check whether your street is inside a declared zone.
Evictions Take Longer
Proceedings against vulnerable households now involve social services and extra procedural steps. Landlords should assume a slower timetable and keep written records of every notice sent.
Short-Term and Holiday Lets: The Big 2026 Change
This is where the rules moved most, and where owners are most likely to get caught out.
The National Registry Was Struck Down
Royal Decree 1312/2024 created a single national rental registry and a national registration number, compulsory from 1 July 2025 for anyone advertising on booking platforms. On 19 May 2026 the Supreme Court annulled that national registration procedure in judgment 620/2026, following an appeal by the Valencian government. A second ruling two days later reached the same conclusion.
Regional Licences Are Now What Count
What survived is the Digital Single Window and the duty on platforms to share data. The decisive authorisation is once again the regional tourist registry: VT or EGVT in the Valencian Community, VFT in Andalusia, HUT in Catalonia, and the equivalent in other regions. Platforms still ask for a code before a listing goes live, so in practice the regional number must appear on every advert.
A New Annual Return Every February
Owners of short-term and seasonal lets must now file an annual informative return covering the previous calendar year. It asks for arrival and departure dates, guest numbers and the purpose of each stay. The first filing covered 2025 lettings, with a deadline of 2 March 2026. Missing it can lead to a registration code being cancelled and listings being pulled.
Regional and Local Limits Still Apply
Cities including Barcelona, Madrid, Malaga and Palma have their own restrictions on new tourist licences, and many communities of owners can now block short lets in their building. A national code never overrides those local rules.
What Landlords Should Do Now
- Check your zone. Confirm whether the property sits inside a declared stressed area before setting a new rent.
- Confirm your regional licence. For holiday lets, make sure the regional tourist number is valid and shown on every listing.
- Diarise February. Put the annual short-let return in the calendar each year, with the booking data ready.
- Update your contracts. Review rent review clauses, fee clauses and deposit terms against the current rules.
- Keep records. Store notices, invoices and booking data, since enforcement now relies on cross-checked data.
What This Means for Property Owners Abroad
Non-resident owners face the same duties as residents, plus their own tax filings. If you manage the property from another country, appoint someone local who can respond to notices, handle inspections and keep the licence current. Good record keeping matters more than ever, and the same discipline that supports a well-run maintenance schedule applies here.

Where to Check the Official Position
Rules continue to move, and regional differences are wide. Before letting a property, confirm the current position with your regional housing authority or a Spanish lawyer. This summary of the registry and annual reporting rules is a useful starting point.
