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:

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:

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.
ProvisionStatus after Ruling 620/2026
Registro Único (national property registry)Annulled — no longer a legal requirement
National registration number requirement for listingsAnnulled — flows from the annulled registry
Ventanilla Única Digital de ArrendamientosRemains in force (data-sharing tool)
Platform data reporting obligationsRemains 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:

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:

ObligationAffected by ruling?
Modelo 210 — annual non-resident income tax on rental incomeNo — unchanged
IGIC registration and quarterly returns (where applicable)No — unchanged
IBI (local property tax) and basuraNo — unchanged
Imputed income tax for vacant periodsNo — unchanged
Capital gains tax on future saleNo — unchanged
Tourist licence (Vivienda Vacacional) requirementNo — unchanged
National Registro Único registrationYes — 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:

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:

  1. If you already have a Canary Islands Vivienda Vacacional registration: continue as normal. Nothing changes for you.
  2. 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.
  3. 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.
  4. 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.

Frequently Asked Questions

Does the Supreme Court ruling mean I no longer need to register my rental property in Spain?
Not entirely. The national Registro Único created by Royal Decree 1312/2024 has been annulled — so you are no longer required to register at national level. However, regional registries run by the Autonomous Communities remain fully in force. In Lanzarote, the Canary Islands Tourism Registry registration (Vivienda Vacacional) is still a legal requirement before you can list your property on any platform.
Do I still need to comply with the Ventanilla Única Digital de Arrendamientos?
The Ventanilla Única Digital was not annulled by the Supreme Court. However, its practical role has changed: it can no longer impose a national registration process on property owners. It remains a channel for platforms to exchange data with authorities, but you are not required to register through it in order to list your property.
My Lanzarote property is registered with the Canary Islands tourism registry — is that still valid?
Yes, completely. The Supreme Court ruling only annulled the national registry created by Royal Decree 1312/2024. Regional registries — including the Canary Islands Vivienda Vacacional register — are separate legal instruments under regional competence and are entirely unaffected. Your registration remains valid and is still required.
What happens if I already registered with the national Registro Único?
The registration you completed has no legal effect going forward, since the registry itself no longer exists. You are not penalised for having registered, but you gain no ongoing obligation from it either. Continue to maintain your regional registration (Canary Islands Tourism Registry) as your primary compliance requirement.
Will Airbnb and Booking.com remove the registration number requirement?
Platforms are required under EU Regulation 2024/1028 to verify registration numbers. With the national registry annulled, they should accept regional registration numbers (from the Canary Islands or other Autonomous Communities) as the compliant identifier. Platform policies take time to update — if you have a valid regional registration number, continue using it in your listings.
Could the Spanish State create a new national registry to replace the one annulled?
Theoretically yes, but only if it finds a valid constitutional basis — which the Supreme Court determined does not currently exist under Art. 149.1.8 CE, Art. 149.1.13 CE, or Art. 149.1.31 CE. Any future attempt would need to be carefully structured, likely requiring cooperation agreements with the Autonomous Communities rather than a unilateral national imposition.
