Spain faces EU legal action over tax on non-resident homes

The European Commission has taken formal action against Spain over its tax treatment of non-resident property owners, issuing a reasoned opinion that requires the country to amend its legislation or face further legal proceedings at EU level. The case concerns Spain’s system for taxing property owned by individuals who are not tax residents but who use their homes in Spain as their main residence.

Under current rules, non-resident owners are required to pay an imputed income tax on their property, even when it is not rented out and is used as a personal home. The Commission has stated that this approach may be incompatible with EU law, particularly in relation to the free movement of capital and workers within the European Union.

Two-month deadline set before escalation

As part of the infringement procedure, Brussels has issued a formal notice requiring Spain to respond within two months. If the government does not bring its rules into line with EU requirements, the case may be referred to the Court of Justice of the European Union for a binding ruling.

The Commission’s action represents the final stage before court referral, known as a reasoned opinion, which indicates that earlier discussions and warnings have not resolved the issue. Officials argue that Spain’s current tax framework places non-resident property owners at a disadvantage compared with residents in similar circumstances.

Tax rules at the centre of dispute

At the heart of the case is Spain’s imputed income tax system, applied to property owned by non-residents under the Non-Resident Income Tax (IRNR) regime. Under this system, non-resident owners are required to declare a notional rental value for properties they own in Spain, even if those homes are not rented out. This is typically calculated as a percentage of the property’s cadastral value and taxed accordingly.

The European Commission’s concern is that this obligation continues to apply even when the property is used as the owner’s permanent residence, creating a difference in treatment compared with tax residents in Spain. Residents are generally taxed on worldwide income but are not subject to the same imputed charge on their main home in the same way non-residents are.

EU legal framework and equal treatment principles

The Commission’s position is based on EU treaty provisions that guarantee the free movement of capital and non-discrimination between EU citizens when exercising cross-border rights. Brussels argues that tax measures which discourage individuals from owning or maintaining property in another member state may constitute an obstacle to these freedoms.

In this case, the Commission considers that Spain’s rules could deter EU citizens from purchasing or using property in the country as a residence if they are not formally tax residents. The infringement procedure is part of the Commission’s wider role in ensuring that national tax systems comply with EU law and do not create unjustified barriers within the single market.

Spain’s position and potential implications

Spanish authorities now have the opportunity to respond to the Commission’s concerns and either justify the current system or propose amendments. No official change has yet been confirmed. If the matter proceeds to the Court of Justice, the court could issue a binding judgment requiring Spain to amend its tax legislation.

Such rulings are enforceable and may require legislative changes to ensure compliance. The outcome could also have implications for other EU member states with similar tax structures applied to non-resident property owners, particularly in countries with significant levels of foreign property ownership.

Broader context of EU tax oversight

The case is one of several examined by the European Commission concerning national tax rules that may affect cross-border property ownership or investment.

While taxation remains a national competence, EU law limits the extent to which member states can apply measures that disproportionately affect citizens of other EU countries. In recent years, several infringement procedures have been opened relating to property taxation, inheritance rules and capital movement restrictions.

Next steps in the procedure

Spain is expected to submit a formal response to the Commission within the specified deadline. This response may include clarification of the legal framework or proposals for amendment. If the Commission considers the response insufficient, it may escalate the case to the Court of Justice of the European Union for a final ruling.

For now, the process remains at the pre-litigation stage, but the deadline places pressure on Spain to address the concerns raised or justify the continued application of its current tax rules for non-resident property owners.
