Own Property in Spain But Don't Live There? What Non-Residents Need to Know in 2026

Four Key Changes for 2026

Whether you own an apartment on the Costa Blanca or a rural finca in Galicia, the rules around Spanish property tax for non-residents are shifting — and staying compliant has never mattered more. Here are the four changes every non-resident property owner should know about.

1. Holiday Rental Registration: The NRA Requirement

If you rent your Spanish property through platforms like Airbnb, Booking.com or Vrbo, you must now hold a Rental Registration Number (NRA — Número de Registro de Alquiler) through Spain's national short-term rental register.

Since July 2025, this registration has been mandatory. Without it, platforms may remove or block your listing. No NRA number, no online listing.

2. New Annual Rental Declaration

Starting January 2026, simply holding your NRA is no longer enough. All NRA holders must now submit an annual rental activity declaration — an official report covering the number of guests per booking, dates of stay and reasons for stay.

The filing window for 2026 was 1 February – 2 March. Miss it, submit it incorrectly, or leave information incomplete, and the consequences are serious: your NRA can be revoked.

3. Non-EU/EEA Owners: Spain May Owe You Money

For years, non-residents from outside the EU/EEA renting out Spanish property have been taxed on gross rental income at 24% with zero ability to deduct costs like maintenance, insurance, mortgage interest or management fees. EU/EEA-based landlords, by contrast, have always been able to deduct these expenses.

A final Supreme Court ruling is expected in 2026. If it goes as most tax experts anticipate, it could open the door to significant refunds for non-EU/EEA owners. But the four-year statute of limitations means refund windows are closing on a rolling basis — many owners are already filing preventive claims now.

4. Imputed Income Tax Under Investigation

The European Commission has opened formal proceedings against Spain over imputed income tax — the annual tax applied to non-resident property owners based on 1.1–2% of the property's cadastral value, even if the property isn't rented and is only used occasionally.

The Commission is examining whether this creates unequal treatment between residents and non-residents. A final ruling is expected in 2026 or 2027. If Spain is required to change the rules, non-resident owners could benefit from the same treatment as residents.

Don't Forget the Modelo 210

All non-resident property owners in Spain must file the Modelo 210 tax return to declare imputed income, rental income and any capital gains on sale. Keeping filings up to date ensures you're well-positioned to act on any rule changes — and avoids penalties.
