The Ruling: What the Supreme Court Decided
Spain's Supreme Court (Tribunal Supremo), in Ruling 620/2026 dated 21 May 2026, partially annulled Royal Decree 1312/2024 of 23 December 2024 — the regulation that created the Registro Único de Arrendamientos de Corta Duración (national short-term rental registry).
The case was brought by the Generalitat Valenciana, which argued that the State had overstepped its constitutional authority by creating a national registry that overlapped with — and in practice supplanted — the regional registries already operated by Spain's Autonomous Communities.
The court agreed. In its ruling, it found that the State had created "an exhaustive regulation of a national registry that is superimposed on the existing regional registries" — and that no constitutional basis exists for this.
Bottom line: The national short-term rental registry (Registro Único) no longer exists as a legal requirement. Property owners are not required to register at national level before listing on Airbnb, Booking.com or any other platform.
What Was Annulled
The annulled provisions are those of Royal Decree 1312/2024 that established the Registro Único de Arrendamientos de Corta Duración specifically — the mechanism requiring individual property owners to obtain a national registration number before listing their property on digital platforms.
The court considered three constitutional titles the State had cited as justification, and rejected all three:
- Art. 149.1.8 CE — civil legislation and public registries: the court found this did not give the State authority to create a tourism-related property registry
- Art. 149.1.13 CE — bases of economic planning: the ruling determined the registry exceeded what "basic" economic coordination allows
- Art. 149.1.31 CE — state statistics: the court held that statistical purposes alone cannot justify a compulsory registration system for individual properties
Crucially, the court also addressed the EU angle: EU Regulation 2024/1028 (which requires Member States to put in place registration systems for short-term accommodation) does not specify that the registration process must be managed at national level. Regional systems are fully compatible with the Regulation.
What Was NOT Annulled: The Ventanilla Única and Data Obligations
The Supreme Court did not annul everything in Royal Decree 1312/2024. The following remain in force:
- The Ventanilla Única Digital de Arrendamientos (digital single window) — a platform designed to centralise the flow of data between regional registries and national/European databases
- The obligation on digital platforms (Airbnb, Booking.com, Vrbo, etc.) to transmit rental data to the authorities
- The transmission of data for statistical purposes
Important distinction: The Ventanilla Única is not a registry that you register with as a property owner — it is a data-sharing infrastructure for authorities and platforms. Its survival does not affect the practical obligation on individual owners, which was tied to the annulled registry.
| Provision | Status after Ruling 620/2026 |
|---|---|
| Registro Único (national property registry) | Annulled — no longer a legal requirement |
| National registration number requirement for listings | Annulled — flows from the annulled registry |
| Ventanilla Única Digital de Arrendamientos | Remains in force (data-sharing tool) |
| Platform data reporting obligations | Remains in force (Airbnb, Booking.com etc. still report) |
| Regional registries (e.g. Canary Islands Vivienda Vacacional) | Unaffected — separate legal instruments |
What This Means for Lanzarote Holiday Rental Owners
If you own a holiday rental property in Lanzarote, the ruling has one practical consequence: you are no longer required to register in the national Registro Único or obtain a national-level registration number.
Beyond that, your other obligations remain unchanged. The national registry was always an additional layer on top of the existing Canary Islands system — and it is only that additional layer that has been removed.
The Canary Islands Tourism Registry Still Applies
The Canary Islands operates its own registration system for short-term tourist accommodation — the Vivienda Vacacional register, managed by the regional government (Gobierno de Canarias). This is a regional instrument, operating under Canary Islands tourism law, and is completely independent of the national registry struck down by the Supreme Court.
You still need:
- A valid Vivienda Vacacional registration from the Canary Islands Tourism Registry before listing your property
- Your regional registration number displayed on all advertising — on Airbnb, Booking.com, and any other platform
- Compliance with the minimum habitability and safety standards set by Canary Islands law
None of this has changed. The Supreme Court ruling specifically and exclusively removes the national layer.
What About Airbnb, Booking.com and Other Platforms?
Under EU Regulation 2024/1028, platforms operating short-term rental markets in Spain are required to verify registration numbers for listed properties. With the national registry annulled, platforms should accept regional registration numbers (issued by the Autonomous Communities, such as the Canary Islands Vivienda Vacacional number) as the relevant compliance credential.
In practice, platform policies take time to update. If you currently have a valid Canary Islands registration number, continue using it in your listings. It remains the correct and legally compliant identifier for your property.
Platforms are also still required to report your rental data to the Spanish authorities — that obligation was not affected by the ruling. There is no change to the AEAT's visibility of rental income declared (or not declared) by hosts.
No change to tax reporting: Airbnb and Booking.com continue to report your rental income to the Spanish Tax Agency via Modelo 179. The Supreme Court ruling concerns registration, not taxation. Your fiscal obligations as a non-resident landlord remain exactly as they were.
Your Remaining Tax Obligations
For non-resident property owners renting in Lanzarote, the full tax picture is unchanged. A summary of what still applies:
| Obligation | Affected by ruling? |
|---|---|
| Modelo 210 — annual non-resident income tax on rental income | No — unchanged |
| IGIC registration and quarterly returns (where applicable) | No — unchanged |
| IBI (local property tax) and basura | No — unchanged |
| Imputed income tax for vacant periods | No — unchanged |
| Capital gains tax on future sale | No — unchanged |
| Tourist licence (Vivienda Vacacional) requirement | No — unchanged |
| National Registro Único registration | Yes — annulled, no longer required |
The January 20 filing deadline for Modelo 210, the 7% IGIC rate for holiday rentals that include services, and the 19%/24% non-resident income tax rates — all of these are governed by separate legislation that the Supreme Court ruling does not touch.

Could the State Create a New National Registry?
The ruling does not permanently close the door on a national registration system. What it does is establish clearly that the State cannot create one unilaterally under the constitutional articles it cited in Royal Decree 1312/2024.
A constitutionally valid approach would likely require either:
- Cooperation agreements with the Autonomous Communities, rather than imposing a national registry over their existing systems
- A different constitutional basis — one the court has not yet considered
- A legislative reform at the level of an organic or basic law, with proper allocation of competences between central and regional government
None of these are imminent. For now, the practical consequence is clear: no national registry exists, and owners must comply only with their relevant regional registration system.
What Should You Do Now?
The practical steps for Lanzarote holiday rental owners following this ruling are straightforward:
- If you already have a Canary Islands Vivienda Vacacional registration: continue as normal. Nothing changes for you.
- If you had obtained a national Registro Único number: that number is now without legal basis. Your regional registration number (Canary Islands) remains your primary compliance credential. Update your listings to show the regional number if you had replaced it.
- If you have not yet registered with the Canary Islands Tourism Registry: this obligation remains. You cannot legally advertise your property on rental platforms without a valid regional registration.
- Review your Modelo 210 and IGIC status: the ruling changes nothing here. If you have not been filing correctly, now is the time to regularise — platforms continue to report your income to the AEAT.
