Form 720 ([Modelo 720](/en/glossary/modelo-720)) is the information return on assets and rights held abroad that must be filed by Spanish tax residents when the value of their overseas assets exceeds certain thresholds. Since its introduction in 2012, this form has been one of the most contentious obligations between the Spanish tax authorities and taxpayers with international assets. The Court of Justice of the European Union (CJEU) ruling of January 2022 partially reformed the penalty regime, but the obligation to declare remains fully in force for the 2025 tax year, with a filing deadline of 31 March 2026.
What Form 720 Is and Its Legal Basis
Form 720 originates from Ley 7/2012, of 29 October, amending tax and budgetary legislation, which introduced into the General Tax Law (LGT), the IRPF Law and the Corporation Tax Law the obligation to report overseas assets and rights. The implementing framework was completed by Ministerial Order HAP/72/2013, which approved the form and established the filing procedure.
The official justification for the form was to combat tax fraud linked to undeclared offshore assets. Its original penalty regime — with penalties of up to 150% of the value of undeclared assets and no limitation period — was challenged before the CJEU by the European Commission on the grounds that the penalties were disproportionate and contrary to fundamental EU freedoms.
The CJEU ruling of 27 January 2022 (Case C-788/19) upheld the Commission’s position on the disproportionality of the penalty regime. Spain was required to amend its legislation through Royal Decree-Law 13/2022, bringing penalties into line with the parameters required by the CJEU. However, the ruling did not eliminate the filing obligation: Form 720 remains mandatory and non-compliance remains penalisable, albeit with reasonable and proportionate penalties.
Who Is Obliged to File: Declarants and Declarable Items
The obligation to file Form 720 applies to the following categories of persons:
Natural persons who are Spanish tax residents. Anyone with their tax residence in Spain — regardless of nationality — who is a holder or holds powers of disposal over overseas assets exceeding the threshold is obliged to declare. Spanish tax residence is determined by time of presence (more than 183 days per year), by the location of the main centre of economic interests, or by the residence of the spouse and minor children.
Legal entities and organisations with a Spanish fiscal domicile. Mercantile companies, foundations, associations, joint-ownership arrangements and any other entity, whether or not having legal personality, that is domiciled for tax purposes in Spain must file Form 720 if they have overseas assets exceeding the thresholds.
Holders, beneficiaries, authorised signatories and representatives. Not only outright holders, but also those who appear as beneficiaries, authorised signatories, beneficial owners or with powers of disposal over the assets are obliged to declare. This is particularly relevant for bank accounts with multiple authorised signatories, or for assets in trusts or fiduciary structures where the taxpayer is a beneficiary.
The Three Declarable Categories
Form 720 is structured around three distinct blocks, each with its own €50,000 threshold:
Block 1: Accounts at Overseas Financial Institutions
This covers current accounts, savings accounts, term deposits, securities accounts and any other accounts held at banks, savings banks, credit cooperatives or any other financial institution situated outside Spain. The value to be declared is the balance at 31 December of the relevant year and the average balance in the fourth quarter. If the balance at 31 December exceeds €50,000, the entire block must be declared.
All accounts within the block must be declared if the value of any one exceeds the threshold — it is not sufficient to declare only the account that exceeds it.
Block 2: Securities, Rights, Insurance Policies and Income Abroad
This block covers shares, participations and securities traded on foreign markets; life or disability insurance policies taken out with an insurance company domiciled abroad; rights under pension plans and pension funds managed abroad; and temporary or lifetime annuities contracted with foreign insurers.
The value is calculated using the listed price of traded securities at 31 December, or the surrender or net asset value at that date for non-traded assets.
Block 3: Immovable Property and Rights over Overseas Property
This block covers all immovable property situated abroad — apartments, houses, commercial premises, land, industrial units — of which the declarant is the owner, as well as real rights over property: usufruct, bare ownership, surface rights, administrative concessions over foreign property.
The declaration value is the higher of the acquisition price, the market value at 31 December and the foreign cadastral value (if one exists). Documenting the valuation used is recommended.
The €50,000 Threshold: Calculation and Common Situations
The €50,000 threshold applies independently to each of the three blocks. If overseas bank accounts total €45,000 but overseas property exceeds €60,000, only the property block must be declared.
A common situation is a taxpayer with several overseas bank accounts, none of which individually exceeds €50,000, but whose aggregate balance does. In this case the filing obligation exists: the threshold applies to all accounts in the block collectively, not to each account individually.
To determine whether the threshold is met for Block 2, all values — shares, insurance policies, overseas pension plans — held by the declarant abroad are aggregated. If the total exceeds €50,000, the entire block must be declared.
Filing Deadline: 1 January to 31 March
The filing window for Form 720 for the 2025 tax year runs from 1 January 2026 to 31 March 2026. No extension exists. Filing is exclusively electronic via the AEAT’s online portal (sede.agenciatributaria.gob.es), using a recognised digital certificate, electronic national identity card or cl@ve.
A taxpayer without electronic identification means may authorise a third party (tax adviser, agent) to file on their behalf under a registered power of attorney or representation with the AEAT.
Significant Changes and the Update Obligation
Once the initial return has been filed, there is no obligation to file in subsequent years unless a significant change occurs in any of the declared blocks. A significant change is defined as:
- The value of any block increases by more than €20,000 compared to the last year in which the return was filed.
- The ownership or rights declared are extinguished (sale of the property, account closure, transfer of securities).
In these cases, an updated return must be filed in the ordinary period of the following year. Extinguishment of ownership without a new return may create discrepancies that the AEAT will detect by cross-referencing with IRPF returns or other sources.
Penalty Regime Following the CJEU Ruling
The reform of Form 720’s penalty regime, implemented through Royal Decree-Law 13/2022, establishes the following penalties:
Late filing without prior AEAT demand: €100 per item or set of items relating to the same asset, with a minimum of €1,500 per return.
Late filing following a prior AEAT demand: €200 per item or set, with a minimum of €3,000.
Filing with incomplete, inaccurate or false information: €200 per item or set, with a minimum of €3,000.
These penalties are significantly lower than those in force before the CJEU ruling, which could reach 150% of the value of undeclared assets. However, it is important to note that the consequences of non-compliance extend beyond the formal penalty: if the AEAT identifies undeclared overseas assets that cannot be justified by previously taxed income, it may open IRPF or Corporation Tax inspection proceedings with the corresponding penalties for concealment.
The Relationship Between Form 720 and Income and Corporation Tax
Form 720 is purely informational, but its contents are a fundamental cross-checking tool for the AEAT. The assets and rights declared on the 720 must be consistent with the income declared on the IRPF return:
- Interest generated by overseas bank accounts must appear as investment income (rendimientos del capital mobiliario).
- Dividends from foreign shares must be included in the savings base.
- Rental income from overseas property must be declared as property investment income (rendimientos del capital inmobiliario).
- Gains from the disposal of any asset declared on the 720 must have been included in the IRPF savings base.
Discrepancies between what is declared on the 720 and what is included on the IRPF return are one of the AEAT’s most active areas of scrutiny. The expansion of automatic tax information exchange between countries — the Common Reporting Standard (CRS) and FATCA for US accounts — means the AEAT has growing access to information on overseas assets and income without requiring individual requests.
Exceptions and Situations Not Generating a Filing Obligation
Not every connection to overseas assets triggers the Form 720 obligation. The following fall outside the obligation:
- Spanish financial institutions: accounts held at Spanish branches of foreign banks are not included in Block 1, as the institution is already subject to oversight in Spain.
- Companies listed on regulated markets: securities of entities listed on organised markets in Spain or the EU with equivalent recognised status do not trigger a Block 2 obligation, provided the company fulfils its own reporting obligations.
- Assets covered by other returns: transactions already reported under Form 349 (intra-Community transactions) or other information returns with an equivalent purpose may be excluded.
- Taxpayers with a balance below the threshold in all blocks: if none of the three blocks exceeds €50,000, there is no filing obligation.
Planning and Best Practices
Correct management of Form 720 requires maintaining an up-to-date record of overseas assets throughout the year, not just at 31 December. Best practices include:
- Maintaining an up-to-date inventory of overseas accounts, securities and property with their values at each quarter-end.
- Reviewing in October or November whether the value of any block is approaching the €50,000 threshold to anticipate the filing obligation.
- Verifying that the income generated by the assets declared on the 720 is correctly reflected on the draft IRPF return or in the company’s accounting records.
- Retaining documentation of the declared assets: bank statements, property deeds, securities balance certificates.
BMC advises on the preparation and filing of Form 720 and on checking consistency between the declared assets and the income included in the IRPF return. If you have questions about whether your overseas assets trigger a filing obligation, consult our tax planning team before the 31 March deadline.
Frequently Asked Questions about Form 720
What happens if I file Form 720 late but voluntarily?
Voluntary late filing, without the AEAT having previously issued a demand, attracts a penalty of €100 per item or set, with a minimum of €1,500. This is significantly lower than the penalty that applies where late filing occurs after an AEAT demand. In any event, voluntary filing — even if late — is preferable to not filing and waiting for the AEAT to initiate proceedings.
How long does the AEAT have to investigate Form 720?
The limitation period for the formal infringement arising from non-compliance with Form 720 is four years from the day after the filing deadline expired. However, if the AEAT identifies overseas assets that should have been declared and the funds cannot be justified from a tax perspective, it may open IRPF or Corporation Tax inspection proceedings with their own independent limitation periods. Any action by the AEAT interrupts the limitation period and restarts the four-year clock.
