Can a non-resident reclaim Spanish wealth tax?
Possibly. In rulings of 29 October and 3 November 2025 the Spanish Supreme Court held that denying non-residents the 60% combined-tax limit (the “fiscal shield”) breaches EU free movement of capital. If you paid Spanish Wealth Tax or the Solidarity Tax on Large Fortunes (ITSGF) as a non-resident, you may be entitled to a refund of the excess. Time limits apply, so the position is worth checking now.
For years, non-residents who owned high-value assets in Spain were treated less favourably than residents under the Wealth Tax (Impuesto sobre el Patrimonio) and the State Solidarity Tax on Large Fortunes (Impuesto Temporal de Solidaridad a las Grandes Fortunas, “ITSGF”). That has now changed — and for some owners it means money was overpaid that can be claimed back.
What the 2025 rulings actually decided
The “fiscal shield” (escudo fiscal) is a long-standing rule that caps the combined bill of personal income tax (IRPF), Wealth Tax and the ITSGF at 60% of the taxpayer’s IRPF taxable base. Residents could apply this limit; non-residents, who are taxed in Spain only on their Spanish assets, were effectively shut out of it.
In two judgments — 29 October 2025 and 3 November 2025 — the Supreme Court ruled that this exclusion is discriminatory and contrary to the EU principle of free movement of capital. The economic-administrative tribunal (TEAC) had reached a similar conclusion on 24 September 2025. The combined effect: non-residents may now apply the 60% limit, and those who paid more than the limit allowed may claim the difference back.
Who is most likely to have a claim
- Non-resident owners of high-value Spanish property and assets — including UK nationals who became non-resident or were treated as such after Brexit.
- Those whose net Spanish wealth brought them within Wealth Tax or the ITSGF (the ITSGF is a state tax on net wealth above €3,000,000, with a €700,000 exempt minimum).
- Owners who paid the full Wealth Tax / ITSGF without the benefit of the 60% combined-tax limit in recent years.
Whether a refund is available — and how much — depends on your asset mix, the years involved, and the tax actually paid. This is exactly the kind of case that needs an individual review rather than a rule of thumb.
A note on Andalucía
Andalucía applies a 100% allowance on its Wealth Tax. However, where the state ITSGF applies, that allowance does not simply cancel the bill: a variable mechanism links the two taxes, so the interaction has to be calculated case by case. Owners in the Campo de Gibraltar and the wider Costa del Sol should not assume the regional allowance removes a potential ITSGF liability — or a potential refund claim.
Time limits
Refund claims for overpaid tax in Spain are subject to limitation periods, and a claim that is left too late can be lost. The exact window that applies to your situation depends on when and how the tax was paid, so the safe course is to have your position reviewed promptly rather than waiting.
How Costaluz can help
From our Algeciras office — about 20 minutes from Sotogrande — Costaluz Lawyers has advised international clients on Spanish property and tax since 2006, led by María Luisa de Castro, ICA Cádiz nº 2745. We can review what you paid, tell you honestly whether a refund claim is realistic, and handle it if it is. We act for you, in English or Spanish.
How a non-resident wealth-tax reclaim works
- We check whether you have a claim. One call and the value of your Spanish assets is usually enough to tell.
- We file a rectification of your self-assessment (rectificación de autoliquidación) for the years that remain open.
- The tax administration reviews it. Timescales vary by office and case.
- If accepted, the overpaid amount is refunded, with interest where due.
The window is not indefinite
Refund claims are subject to a four-year limitation period, and which years are still open depends on when you filed each return — so the sooner you let us check, the more years you are likely to keep available. Leave it too long and a year is lost for good.
We cover this in depth at our free webinar on 23 July.

Frequently asked questions — non-resident wealth tax refunds
What is the “fiscal shield” and why does it matter?
It is a rule that caps the combined total of IRPF, Wealth Tax and the ITSGF at 60% of your income-tax base. Residents could use it; non-residents could not. The 2025 Supreme Court rulings opened it to non-residents, which can reduce or refund tax that was previously overpaid.
Does this apply to UK nationals after Brexit?
The rulings are grounded in free movement of capital, which applies regardless of where the taxpayer is resident — including outside the EU. UK non-residents who paid Spanish Wealth Tax or ITSGF should have their position reviewed.
How far back can I claim?
Spanish tax refunds are subject to limitation periods, and the window that applies depends on when and how you paid. We will check the specific deadlines for your case — but the sooner you ask, the more options you are likely to have.
Is the initial review free?
Yes — we give you a free written analysis of whether a claim is realistic before any engagement. We never charge to tell you that you do not have a case.
