Foreign Assets Declaration (Modelo 720) Spain

The Foreign Assets Declaration Modelo 720 Spain is the mandatory informative tax return through which Spanish tax residents must disclose assets and rights located abroad that exceed €50,000 per category, pursuant to the obligation created by Ley 7/2012, de 29 de octubre, Article 1, which introduced the Disposición Adicional Decimoctava (DA 18ª) into Ley 58/2003, de 17 de diciembre, General Tributaria. The Modelo 720 is administered by the Agencia Estatal de Administración Tributaria (AEAT) and is filed electronically through the AEAT's Sede Electrónica using a certificado digital or Cl@ve PIN.

The obligation applies to Spanish tax residents — both individuals and legal entities — who hold, as of 31 December of the declaration year, foreign assets in any of three categories exceeding €50,000 each: (1) accounts in financial institutions abroad (cuentas en entidades financieras en el extranjero); (2) securities, rights, insurance, and income deposited, managed, or obtained abroad (valores, derechos, seguros y rentas); and (3) real estate and rights over real estate located abroad (bienes inmuebles y derechos sobre los mismos). The threshold is applied independently to each of the three categories — a taxpayer may owe a Modelo 720 for overseas real estate but not for foreign bank accounts if accounts are below €50,000.

The Modelo 720 was introduced in 2012 as part of Spain's anti-tax-fraud measures, originally carrying extremely harsh sanctions for non-disclosure — originally including unlimited penalties and potential attribution of undeclared assets as hidden income (ganancias patrimoniales no justificadas). However, the Court of Justice of the European Union (CJEU) ruled in Case C-788/19 (Comisión v. España, 27 January 2022) that several aspects of the Spanish Modelo 720 penalty regime were incompatible with EU law's free movement of capital (Article 63 TFEU). Following this ruling, Spain enacted Real Decreto-Ley 3/2022, de 1 de marzo, substantially reforming the sanction regime — the disproportionate unlimited penalties and the unlimited prescription period were eliminated, and the penalty framework was brought into line with the standard Ley 58/2003 General Tributaria sanction regime.

As an informative declaration (declaración informativa), the Modelo 720 itself does not create a direct tax liability — it is not a tax payment form. Its purpose is to provide information to the AEAT enabling cross-referencing with income and wealth declarations (IRPF, Modelo 714 Wealth Tax, Impuesto sobre Sociedades) and to detect undeclared offshore wealth. Failure to declare does not automatically generate a tax liability, but once the AEAT discovers undeclared foreign assets through third-party exchange of information under the Common Reporting Standard (CRS/DAC2), FATCA agreements, or bilateral tax treaties, it may attribute those assets as unjustified gains (ganancias patrimoniales no justificadas) under Article 39 of Ley 35/2006 del IRPF, taxed at the marginal IRPF rate, plus surcharges and interest.

The declaration covers the balance as of 31 December, and also the maximum balance reached during the year for bank accounts. For the Modelo 720 to be obligatory in subsequent years, the balances must have increased by more than €20,000 compared to the previously declared values — this updating threshold prevents taxpayers from having to re-file every year for stable positions. The AEAT provides detailed completion instructions in its online help portal and publishes annual FAQ updates addressing new asset categories, cryptocurrency treatment (now covered under Modelo 721, introduced separately), and changes in reporting thresholds.

A Foreign Assets Declaration Modelo 720 Spain is required when a Spanish tax resident — person with residencia fiscal habitual in Spain under Article 9 of Ley 35/2006 del IRPF — holds foreign assets in any of the three regulated categories exceeding €50,000 as of 31 December of the tax year.

Modelo 720 is needed when a Spanish resident holds bank accounts abroad with balances exceeding €50,000 individually or jointly — this includes current accounts, savings accounts, term deposits, and similar instruments held at foreign banks or online banks registered outside Spain. Joint account holders must each declare their proportional share.

The declaration is required when a Spanish resident holds foreign securities — shares in foreign companies, bonds, investment fund units (fondos de inversión), pension plans, or life insurance policies with surrender value — held at foreign brokers, custodians, or financial intermediaries, where the total value across all such assets in Category 2 exceeds €50,000.

Modelo 720 is needed when a Spanish resident owns real estate abroad — apartments, houses, land, or other immovable property — with a total acquisition value or current value exceeding €50,000. This includes property held directly, through foreign companies, or through trusts and similar structures where the Spanish resident is the beneficial owner.

The form must also be filed in subsequent years when any previously declared category's value has increased by more than €20,000 compared to the last declaration, or when new foreign assets in a previously undeclared category now exceed the €50,000 threshold — even if the taxpayer has filed before.

Modelo 720 is required by Spanish company directors, sole traders (autónomos), and beneficial owners of Spanish entities who personally hold foreign assets meeting the thresholds — the obligation is personal and does not transfer to the entity unless the entity itself is the holder.

The declaration is also needed when assets are newly acquired during the year — for example, upon inheriting foreign real estate from a non-resident parent, or receiving a gift of foreign shares — even if those assets were held for only part of the year, as long as the balance as of 31 December exceeds €50,000. Note: cryptocurrency assets are now separately covered under Modelo 721 introduced by Ley 11/2021.

Under Spanish law, the Constitución Española 1978 is the supreme law. The Código Civil governs contractual obligations under Article 1255 (libertad de pactos). The AEAT administers taxation. The Juzgados de Primera Instancia have general civil jurisdiction. The Ley 39/2015 governs administrative procedure. The LOPDGDD (LO 3/2018) and RGPD govern data protection through the Agencia Española de Protección de Datos (AEPD).

A complete Foreign Assets Declaration Modelo 720 Spain under DA 18ª Ley 58/2003 and Ley 7/2012 must contain accurate information for each category of foreign asset to satisfy AEAT reporting requirements and avoid sanctions under the reformed penalty regime.

Taxpayer Identification: Full name, NIE or DNI, and NIF of the declarant. For jointly owned assets, each co-owner files a separate Modelo 720 reporting their proportional share. Legal entities file using their NIF and the company's registered details. The AEAT's electronic system (Sede Electrónica) requires authentication via certificado digital (DNIe, Fábrica Nacional de Moneda y Timbre certificates, or other AEAT-recognised certificates) or Cl@ve PIN.

Category 1 — Foreign Bank Accounts: For each foreign account, the declaration must include: name of the foreign financial institution; country of incorporation; BIC/SWIFT code; IBAN or account number; declarant's ownership percentage; balance as of 31 December; and maximum balance reached during the year. All amounts must be converted to euros at the ECB reference exchange rate on 31 December.

Category 2 — Foreign Securities, Rights, Insurance, and Income: For each foreign security or right: name and country of the issuing entity; ISIN code if listed; type of asset (share, bond, fund unit, insurance, pension plan); number of units or face value; value in euros as of 31 December. For life insurance policies with surrender value, the policy number, issuing company, and surrender value as of 31 December are required.

Category 3 — Foreign Real Estate: For each property: country and full address; cadastral or land register reference if available; date of acquisition; acquisition cost in euros; current estimated value if significantly different from acquisition cost; nature of the right (ownership, usufruct, long-term lease). Properties held through foreign entities require additional disclosure of the entity's name, country, and the taxpayer's interest percentage.

Amendment and Correction: If a previously filed Modelo 720 contained errors, a complementary or substitutive declaration may be filed. The AEAT distinguishes between sustitutiva (replacing the original entirely) and complementaria (adding omitted assets) filings — the correct type must be selected in the form header.

Exchange Rate Conversion: All foreign currency amounts must be converted to euros using the Banco de España or European Central Bank reference exchange rate on 31 December of the declaration year. The AEAT provides official exchange rate tables on its website for each reporting year.
