Spain Tax Ruling for Non Residents 2025

Spain’s Supreme Court has issued a major ruling that could significantly change how foreign non-residents are taxed. On 17 November 2025, the court confirmed that non-residents must be treated equally to residents regarding specific income tax and wealth tax obligations. For expats with holiday homes, rental properties or investments in Spain, this may open the door to tax reductions, refunds, or even changes in long-standing fiscal rules.

What Exactly Did the Supreme Court Decide?

The court ruled that Spain cannot apply more restrictive tax treatment to non-residents in situations that are legally comparable to those of residents. In practical terms, this means non-residents should be able to access certain deductions, offsets or allowances that previously applied only to Spanish tax residents. The ruling specifically targets situations where different treatment would violate EU principles of non-discrimination.

Why This Matters for Foreign Homeowners

Under current law, non-resident property owners pay non-resident income tax (NRIT) on their Spanish properties. This often results in a higher taxable base because non-residents cannot deduct many expenses that residents can. The ruling raises the possibility that certain deductions or allowances could now be applied to non-residents as well, particularly when their circumstances mirror those of residents.

Potential Impact on Wealth Tax

Spain’s wealth tax has long been viewed as punitive for non-residents, who have historically faced fewer exemptions and less generous allowances. The Supreme Court’s decision may challenge this structure, opening the possibility that foreign property owners could be entitled to the same exemptions and allowances that residents enjoy.

Could Non-Residents Claim Refunds?

If the ruling is interpreted broadly, some non-residents may be able to request corrections or refunds for previous tax years. This will depend on how the Spanish tax agency (AEAT) responds and whether further guidance or legislation is introduced. Legal and tax advisors are already examining the ruling for potential claims.

Does This Affect Double Taxation Agreements?

The ruling does not change international agreements, but it may influence how Spain applies those agreements in day-to-day practice. Non-residents will still need to follow the tax treaty between Spain and their home country, but they may now benefit from more favourable domestic treatment inside Spain.

Will the Law Change Next?

The Spanish government may need to update the non-resident tax framework to align with the Supreme Court’s decision. This could involve revising income tax rules, wealth tax allowances or administrative processes. For now, the ruling stands as a direct instruction to apply equal treatment where legally justified.

Who Benefits the Most?

The groups most likely to be affected include:

• Non-resident homeowners with rental properties

• Second-home owners who pay imputed income tax

• Foreign nationals subject to Spanish wealth tax

• Part-time expats who spend limited time in Spain but own property

• Investors with Spanish assets

What Should Non-Residents Do Now?

• Review your most recent non-resident income tax filings

• Check whether you may be entitled to additional deductions

• Discuss possible refunds or corrections with a tax advisor

• Track future announcements from AEAT regarding the ruling

• Prepare for possible legislative changes during 2026

Final Thoughts

This ruling could be one of the most favourable tax developments for foreign property owners in Spain in years. While practical changes will take time, non-residents now have a strong legal basis to request equal treatment and potentially reduce their tax burden. Expats should monitor updates closely as the implications become clearer.
