Spanish tax residents must file **Modelo 720 annually** declaring foreign assets exceeding **€50,000 threshold**, including bank accounts, investments, foreign property, and business interests. Penalties for non-filing were €5,000-100,000+ but have been significantly reduced following EU Court rulings in 2023-2024. Filing is mandatory even if you owe no additional tax.
The Modelo 720 form represents one of Spain's most stringent tax compliance requirements for residents, mandating comprehensive annual reporting of foreign assets held outside Spain. Named for its Spanish tax form number, the Modelo 720 requires declaration of bank accounts, investments, business interests, real property, and other assets located in foreign countries, with a €50,000 threshold triggering filing obligations. For non-residents relocating to Costa Blanca (who become Spanish tax residents upon establishing residence), the Modelo 720 requirement presents immediate compliance challenges—most expatriates maintain significant assets in their home countries (UK bank accounts, US retirement accounts, Australian property) that must be reported to the Spanish tax authority (AEAT—Agencia Estatal de Administración Tributaria). Failure to file or incomplete filing historically resulted in severe penalties, occasionally exceeding €100,000 even absent actual tax evasion. However, a landmark European Court of Justice ruling in 2023 invalidated Spain's most draconian penalties as disproportionate, leading AEAT to reduce penalties substantially in 2024-2025. This guide provides comprehensive coverage of Modelo 720 obligations, recent penalty reforms, practical filing procedures, and strategic approaches to compliance for new residents holding significant foreign assets.

The Bottom Line
The Modelo 720 form, while initially appearing burdensome, has become significantly more manageable following Spain's 2024-2025 penalty reforms. Spanish tax residents must file annually by March 31st, declaring foreign assets exceeding €50,000, but reformed penalties (€50-300 for most compliance gaps) no longer impose draconian financial burdens for honest residents. For non-residents relocating to Costa Blanca and establishing Spanish tax residency, prompt engagement of a Spanish gestor (tax advisor) in the first year of residency ensures proper Modelo 720 compliance, eliminating uncertainty and penalty risk. The filing is straightforward once documentation is organized: compile December 31st balances for all foreign accounts, properties, and business interests, provide information to the gestor, and file by March 31st. Annual compliance in subsequent years is routine. The reformed penalty regime creates incentives for compliance—investing €200-400 in professional filing prevents penalties far exceeding this cost. Additionally, residents should understand that Modelo 720 reporting integrates with automatic information exchange (AEOI/CRS) systems: AEAT receives data about foreign accounts from international financial institutions, making concealment impossible and compliance verification automatic. For US citizens and certain other foreign nationals, additional compliance requirements (FATCA, home-country reporting) may apply alongside Modelo 720, necessitating coordination with specialist advisors. The bottom line: organize foreign asset documentation, engage a competent Spanish gestor, and file Modelo 720 on time and accurately each year. Compliance costs are modest (€200-500 annually for professional filing), penalties under reformed rules are manageable, and peace of mind regarding tax authority compliance is invaluable.
