Tax Haven (Paraíso Fiscal)

What Is a Tax Haven Under Spanish Law?

Spain maintains its own official list of non-cooperative jurisdictions — commonly referred to as paraísos fiscales (tax havens). The list is set by Royal Decree 1080/1991 (as subsequently amended) and is periodically updated. A jurisdiction is removed from the list when it signs an adequate tax information-exchange agreement (TIEA) or double tax treaty with Spain and is no longer considered non-cooperative.

The concept interacts with the EU’s own list of non-cooperative jurisdictions (the “EU blacklist”), though the two lists are not identical.

Current Examples on Spain’s List

Historically listed jurisdictions have included the Channel Islands, Isle of Man, Gibraltar (prior to certain updates), Cayman Islands, British Virgin Islands, Panama, and several others. The list changes over time as jurisdictions sign agreements with Spain. Always verify the current status with an advisor before structuring any transaction.

Legal Consequences of Using a Listed Jurisdiction

When a transaction, entity, or structure involves a jurisdiction on Spain’s list, several adverse tax consequences apply:

For Companies

• Payments to tax havens are non-deductible unless the taxpayer can prove the transaction has genuine economic substance and the price is arm’s-length.
• CFC (Controlled Foreign Company) rules apply with particular force: income earned by a controlled entity in a tax haven is attributed to the Spanish parent without requiring a minimum participation threshold or income type filter.
• Interest and royalties paid to entities in listed jurisdictions are subject to a 24% withholding tax regardless of treaty provisions.

For Individuals

• Individuals who relocate to a listed jurisdiction and declare a change of tax residence are presumed to remain Spanish tax resident for four additional years — they cannot escape IRPF simply by moving to a tax haven.
• Foreign-source income from listed jurisdictions cannot benefit from the participation exemption or treaty relief.

Transfer Pricing Presumption

Transactions with related parties in listed jurisdictions are presumed not to be at arm’s length — the burden of proof reverses to the taxpayer to demonstrate that the price is market-consistent and that there is genuine economic substance.

Substance Over Form: The AEAT’s Approach

The AEAT takes a substance-based approach to tax haven structures. Even when a jurisdiction is not formally listed, the AEAT can challenge arrangements that lack genuine economic substance — for example, a holding company in a low-tax jurisdiction that has no employees, no physical office, and no actual decision-making activity. Spanish GAAR (General Anti-Avoidance Rule) provisions allow the AEAT to recharacterise artificial structures regardless of their legal form.

BEPS and International Context

Spain has implemented the OECD’s Base Erosion and Profit Shifting (BEPS) package extensively. The Country-by-Country Reporting (CbCR) requirement, the Multilateral Instrument (MLI) modifications to Spain’s treaty network, the Anti-Tax Avoidance Directives (ATAD I and II) transposed into Spanish law, and the global minimum tax (Pillar Two, effective for large groups) all form part of the broader anti-avoidance environment.
