A Spanish court says non-EU landlords were overtaxed

Spain runs a two-tier system on rental income. Live in the EU and let out a property here, and you pay tax on what the flat actually earns you, after costs. Live outside the EU, and you have been taxed on the full rent, nothing deductible, at a higher rate. Same flat, same tenant, a different bill, decided by where you happen to be tax-resident.

A Spanish court has now called the worse half of that unlawful. The window to do something about it is open, and it does not stay open forever.

On 28 July 2025, the Audiencia Nacional — Spain's National High Court ruled for a US resident who let out a flat in Barcelona and had been taxed on her gross rent (case SAN 3630/2025). Denying non-EU residents the deductions that EU residents get, the court held, breaches libre circulación de capitales — free movement of capital, the one EU principle that also protects money moving to and from outside the bloc. Confirmed June 2026.

In plain terms, a non-resident from outside the EU who rents out Spanish property can now argue that they should be taxed as an EU resident, on the net figure after costs, and reclaim any overpayment.

This is not really a Brexit story, though post-Brexit British owners living in the UK are squarely in it. It is an EU-versus-non-EU line, and it applies to Americans, Britons abroad, and anyone tax-resident outside the bloc in the same way.

Take a flat bringing in €12,000 a year. Until now, a non-EU owner paid 24% on the whole €12,000, which is €2,880, with no credit for the IBI — council property tax, the agency fee, repairs, or mortgage interest. Deduct, say, €3,000 of genuine costs and the taxable figure drops to €9,000. The bill falls to €2,160. That is €720 per year, claimable for up to 4 years.

Two honest caveats. The headline rate does not move: non-EU owners still pay 24% where EU owners pay 19%, so the gap narrows rather than closes. And this is not yet settled law. The State has already appealed the decision to the Tribunal Supremo — the Supreme Court — and Hacienda has said it will continue rejecting these claims until that court rules. So expect a refusal first, not a quick refund.

That is the argument for filing now rather than waiting. A claim you lodge today preserves the years you can still reach: the right to reclaim looks four years back and rolls forward, so every month you sit on it, an older year drops off the end. File now, and you are in line if the Supreme Court upholds the ruling. Wait for certainty, and the oldest years are gone before it arrives. A rectificación de autoliquidación — correction of a past return, lodged through the Agencia Tributaria's Sede Electrónica (electronic office) or in person at the Málaga delegation on Avenida de Andalucía 2 — keeps those years open. The numbers turn on what you can document, and the law is still moving, so this is one to put in front of a tax adviser before filing, not a DIY afternoon.

If you own here and live elsewhere, this is easy to read about and hard to action from another country, in another language, against a four-year clock. It is the live kind of task we built Navigator for: we can run the claim thread for you.

rectificación de autoliquidación — correction of a past tax return: how you formally ask Hacienda to redo a return you already filed and refund the difference.

devolución de ingresos indebidos — refund of overpaid tax: what you are claiming back when the first return charged you too much.

For years, owning a Spanish flat from outside the EU meant paying tax on rent you never fully kept. A July 2025 ruling calls that discrimination and opens a four-year window to claim some of it back. Hacienda is still saying no while it appeals, so a claim today buys you a place in the queue, not a quick cheque. But wait for the Supreme Court to settle it, and the oldest years are gone before the answer lands. If that is you, worth a proper look this week.

Not bad for a Monday — A. and the WaypointSur team, unusually cheerful about a tax form, for once.
