Spanish tax resident with UK pensions, ISAs, overseas investments, or foreign property? Modelo 720 is mandatory. Own more than €50,000 in ANY asset category and you must file by 31 March each year. Learn what triggers filing, how to value each asset type, recent penalty relief from ECJ rulings, and how voluntary disclosures protect you from enforcement action.
Modelo 720 is a mandatory annual informational declaration of foreign assets (declaración informativa de bienes y derechos en el extranjero) for Spanish tax residents. If you own foreign assets exceeding €50,000 in ANY category—bank accounts, securities, real estate, pensions, life insurance, beneficial interests, or loans extended—you must file the form with Spain's tax authority (Agencia Tributaria) by 31 March each year. This is not a tax itself, but a compliance obligation. Failure to file, or filing late, triggers penalties ranging from €1,000 to €10,000 depending on severity. However, recent European Court of Justice rulings (notably C-788/19 on penalty disproportionality) have led Spain's tax authority to relax enforcement. Voluntary disclosures filed before the authority contacts you receive significantly reduced penalties. The form is filed electronically via Hacienda's website, using your NIE and digital signature or Cl@ve PIN.
Modelo 720 divides foreign assets into three independent categories, each with its own €50,000 threshold. Exceed €50k in ANY category and you must file. The three categories evaluate separately—a €40k bank account balance and a €40k investment portfolio may each fall below the threshold individually, but totaled they still remain separate declarations unless each category independently exceeds €50k.
This category covers all deposit accounts held outside Spain: current accounts (current accounts with UK banks), savings accounts, money market deposits, and deposit certificates. Aggregate all foreign deposit accounts worldwide; if the total exceeds €50,000, you declare. Value each account at its balance as of 31 December. For accounts with fluctuating balances during the year, Spain's tax authority accepts either the year-end balance OR the average balance over the last quarter (October, November, December). You must be consistent year-to-year.
Common examples: UK current account at HSBC (€65,000), ISA savings account (€35,000), Irish savings with Bank of Ireland (€22,000). Total: €122,000—well above the €50k threshold. File this in Section I of the Modelo 720 form. Note that cryptocurrency held in non-custodial wallets is NO LONGER part of Category I as of 2023; instead, crypto is now declared via separate Modelo 721 (covered later in this guide).
This broad category includes shares, bonds, ETFs, unit trusts, mutual funds, life insurance policies, annuities, and structured investment products held abroad. Aggregate the market value of all such holdings worldwide. If the total exceeds €50,000, you declare.
Value each security/policy at its market value as of 31 December. For stocks and ETFs, use closing price on 31 December (or the last trading day of the year). For bonds, use market value if traded on a public exchange; if held to maturity, use the amortized cost or redemption value. For life insurance policies and annuities, use the surrender value or policy value as stated in the insurance company's year-end statement. If market value is unavailable, acquisition cost is acceptable as a fallback.
Common examples: UK investment ISA with £30,000 in stocks, US brokerage account with $25,000 in Apple shares and Vanguard ETFs, German life insurance policy with €35,000 value, Irish-domiciled UCITS fund worth €15,000. Total: €105,000—above threshold. All declared in Section II. Note: crypto held in regulated exchanges or custodial platforms WAS historically included here but is now declared via Modelo 721 as of 2023.
This category covers land, buildings, and legal rights attached to foreign real estate: usufruct, right of habitation, surface rights, or interests in foreign trusts that hold real property. Value real estate by its acquisition cost (precio de adquisición) unless you have a recent professional appraisal showing higher value, in which case use the higher value. Do NOT use Zillow estimates or informal valuations—use the documented purchase price or formal appraisal.
Unlike bank accounts and securities, real estate thresholds are evaluated per property: if you own one UK rental worth €120,000 and another French apartment worth €40,000, both are declared (each individually exceeds or equals €50k in the second case, though €40k doesn't). However, if you own a single property with shared ownership (e.g., you own 50% of a £200,000 UK house worth €120,000), you declare your proportional share: €60,000.
Common scenario: British expat with a UK buy-to-let property purchased for £180,000 (€210,000), a holiday cottage in Portugal (inherited, valued at €85,000), and a 25% stake in a German commercial property held via a foreign real estate fund (€55,000 value). All three exceed the €50k threshold and are declared separately in Section III.
Modelo 720 applies only to assets YOU personally own or co-own. Assets held in the following circumstances are exempt: (1) assets held in trust for you (beneficiary interest) unless you have control; (2) assets you don't legally own but have a contractual right over (e.g., a property you're purchasing but haven't yet received title); (3) assets of deceased relatives (you inherit, but before formal inheritance the assets don't belong to you). Additionally, non-residents who are not Spanish-domiciled do not file Modelo 720 for foreign assets; only Spanish tax residents file. And those under the Beckham Law regime (DNV—Decreto de Nuevos Vecinos, a tax exemption for new residents in years 1–6) are exempt from declaring foreign assets acquired before their residency date, though this exemption is narrowing under recent reforms.
| Category | Threshold | Valuation Method | Key Examples |
|---|---|---|---|
| I. Bank Accounts | €50k aggregate | 31 Dec balance or Q4 average | UK current, savings, ISA deposits |
| II. Securities & Insurance | €50k aggregate | 31 Dec market value | Stocks, ETFs, bonds, life policies |
| III. Real Estate & Rights | €50k per property | Acquisition cost or appraisal | UK property, land, usufruct rights |
Modelo 720 is mandatory for Spanish tax residents (personas físicas—individuals) and Spanish-resident entities (companies, partnerships) that own foreign assets exceeding €50,000 in any category. Your nationality is irrelevant. If you're a Spanish tax resident—whether British, American, Irish, Australian, or any other nationality—you must file if you have foreign assets above the threshold. Tax residency in Spain is typically established if you spend more than 183 days in Spain in a calendar year, or you have your habitual abode in Spain, or your center of economic interests is in Spain.
Non-residents: If you're not a Spanish tax resident but own Spanish property or assets within Spain exceeding €50,000, you file a separate non-resident declaration (Modelo 720-NR or via Modelo 100 for non-residents). However, non-residents do NOT file Modelo 720 for foreign assets.
Joint ownership: If you co-own a foreign asset with a spouse (or another person), both you and your spouse declare 100% of the asset's value in your respective Modelo 720 filings. This is distinct from pro-rata ownership for tax purposes; for Modelo 720, jointly-held assets are declared at full value by each owner. Your tax advisor will confirm the appropriate allocation if you have complex ownership structures (trusts, partnerships, family companies).
Beckham Law and exemptions: Non-residents with Spanish tax residency status under Law 35/2006 (Beckham Law, or DNV regime) enjoy a temporary exemption from declaring foreign assets acquired BEFORE they obtained Spanish tax residency—but this exemption applies only to assets acquired pre-residency and is being narrowed. Check with a tax specialist if you're under the Beckham Law; after year 6 of the regime, the exemption expires and you must file normally.
Accurate valuation is critical for Modelo 720 compliance. The form requires the value of each asset as of 31 December (año natural—calendar year). Here's how to value each category:
For foreign bank accounts, Modelo 720 accepts either the account balance as of 31 December OR the average balance over the final quarter (October, November, December). Choose one method and be consistent year-to-year. The quarterly average is useful if your balance swung above and below €50,000 throughout the year—use the average to show a more representative picture. However, if your balance was stable or consistently above €50k, use the year-end balance for simplicity. Either approach is defensible to Hacienda.
Securities (stocks, bonds, ETFs, mutual funds) are valued at their market value on 31 December. For equity, use the closing price on 31 December (or the last trading day of the year if the market is closed). For bonds, use the mid-market price or amortized cost if trading price is unavailable. For mutual funds and ETFs, use the published net asset value (NAV) as of 31 December. Insurance policies and annuities are valued at their surrender value (valor de rescate) or the policy value (valor de prestación) shown on the insurer's statement as of 31 December. If exact market value is impossible to obtain, document your methodology and retain supporting statements from your financial institutions.
Foreign real estate is valued at its acquisition cost (the documented purchase price) unless you have a professional appraisal showing a higher value, in which case use the higher figure. Do NOT use estimated values (Zillow, Rightmove) or tax assessments from the UK (Council Tax bands) or US (County assessments)—use documented purchase price or a formal appraisal by a qualified surveyor. If you inherited the property, use the inherited value (valor de adquisición en herencia) from the inheritance tax documentation. If you received it as a gift, use the gifted value or a professional appraisal at the time of gift.
All Modelo 720 values are reported in euros. Convert foreign currency balances using the exchange rate applicable on 31 December of the reporting year. Use the official rate published by Spain's Banco de España or your bank's rate on that date. Document the exchange rate used; Hacienda may cross-check if your conversions appear inconsistent.
When you first become a Spanish tax resident and exceed the €50,000 threshold in any category, you must file Modelo 720 for that calendar year by 31 March of the following year. In subsequent years, you file again ONLY if:
The €20,000 threshold is critical: it means you do NOT refile every year if your assets remain stable or grow slowly. This annual relief mechanism reduces filing burden for stable holders. However, retain detailed records of all previously declared amounts in case of audit.
Modelo 720 must be filed electronically with Spain's tax authority (Agencia Tributaria) between 1 January and 31 March of the year following the reporting year. For example, for foreign assets held as of 31 December 2025, you file during January–March 2026. The deadline is firm; late filings incur penalties even if submitted a single day after 31 March. No extensions are granted for Modelo 720 (unlike some other Spanish tax forms). File early—ideally January or February—to avoid technical delays or last-minute errors.
All Modelo 720 filings are electronic. You file via the Agencia Tributaria website (https://sede.agenciatributaria.gob.es) using either your digital certificate or Cl@ve PIN (an electronic government credential). Paper filings are not accepted. You must:
Many expats use a tax representative (gestoría) to file on their behalf; this is highly recommended. A gestoría has bulk-filing credentials and can file your Modelo 720, Modelo 100 (annual income tax return), and any amendments in one coordinated submission. Cost is typically €100–300 per year for Modelo 720 filing alone, or €400–800 if bundled with your full tax return.
The Modelo 720 form is divided into five main sections: (1) Identification (your NIE, name, address); (2) Section I (foreign bank accounts); (3) Section II (foreign securities and insurance); (4) Section III (foreign real estate and rights); (5) Declaration of liability (your signature and authorization). Each section lists the asset, its value, the country, account number or property description, and the percentage you own (100% if solely owned, otherwise your share). Complete all applicable sections. If you have no assets in Category I, leave Section I blank and proceed to Section II.
Failure to file Modelo 720, or filing late, triggers penalties under Spain's Tax Code (Código Tributario—LGT). The penalties are:
However, post-ECJ ruling C-788/19, Spain's Agencia Tributaria has relaxed enforcement. The ruling found that flat penalties on procedural omissions (like missing a deadline by a day) can be disproportionate and violate the principle of proportionality. As a result, Hacienda now often reduces penalties if you file a voluntary rectification (ampliación) BEFORE they initiate contact. Filing late but good-faith may incur only €1,000–€2,000, whereas previously maximum penalties (€10,000) were automatic.
If you miss the 31 March deadline, file as soon as possible. Spanish tax law allows you to file an amendment or rectification (ampliación de declaración) even months or years later. The later the filing, the larger the penalty (€1,000–€10,000), but filing late is always better than not filing at all. If the tax authority initiates an audit or investigation first, penalties are at the high end. If you self-disclose before they contact you, penalties are typically reduced by 50–75% under post-ECJ practice.
As of 2023, cryptocurrency held abroad is NO LONGER declared in Modelo 720. Instead, crypto holdings are declared via Modelo 721 (informative declaration of cryptocurrency holdings). If you hold crypto in any amount (even €1) in a foreign wallet, exchange, or custody account, you must declare it in Modelo 721 with the same deadline (31 March). The threshold for Modelo 721 is the same: €50,000 aggregate. This separate filing stems from Spain's 2022 tax reforms tightening crypto reporting. Failure to file Modelo 721 for crypto assets incurs the same penalties as Modelo 720 omissions.
Many expats believe each account under €50k doesn't require declaration. This is the most common error. You must aggregate all assets in each category: all foreign bank accounts combined, all investment securities combined, all real estate separately. If ANY category total exceeds €50,000, you must file. Even multiple small accounts (€20k + €18k + €15k = €53k) trigger the threshold.
British expats often assume ISAs and private pensions are "tax-free" so don't need declaring to Spain. Wrong. ISAs are declared in Category II as investment securities; private pensions are declared as insurance/pension policies. Even though they're tax-free in the UK, Spain's tax authority requires declaration. Use the account/policy value as of 31 December from your provider's statement.
31 March is a hard deadline. Late filings incur penalties starting at €1,000. File in January or February to avoid technical delays. If you realize in April you've missed filing, file immediately and expect a penalty, but filing late is vastly better than not filing at all.
If you hold accounts in GBP, USD, or other currencies, convert to EUR using the official exchange rate on 31 December (Banco de España rate or your bank's published rate). Hacienda cross-checks major currency conversions; inconsistent rates raise audit flags. Document the rate used; keep bank statements showing both currency and EUR equivalents.
Many people report the death benefit on a life insurance policy rather than the surrender/policy value. Modelo 720 requires the surrender value (the amount you could withdraw today), not the death benefit. Contact your insurer for year-end surrender value. For pensions, use the policy value or projected benefit statement, not the growth/future value estimate.
If your previously-declared foreign assets grow by more than €20,000 in ANY category, you must refile Modelo 720. Many people file once, then assume no further filings are needed if the total doesn't change dramatically. The €20k rule applies even if your total asset value remains below €100k. Track your declared amounts and refile promptly if the threshold is crossed.
This is subtle. If you and your spouse own a UK property jointly, BOTH of you declare 100% of the property value (not 50% each) in your respective Modelo 720s. This is correct. However, if you're filing a joint Modelo 720 (rare), declare jointly-owned assets only once at full value, not twice. Consult your tax advisor on joint vs. separate filings; most expat couples file separately and declare joint assets at 100% in each filing.
As of 2023, crypto is NOT declared in Modelo 720. It's declared in Modelo 721 (separate form, same deadline, same penalties). If you hold crypto abroad and omit Modelo 721, you're non-compliant. Even small holdings (€5,000) must be declared if you have any crypto.
James, a British expat aged 65, moved to Spain in 2024 and obtained Spanish tax residency. He has: (1) UK private workplace pension worth £180,000 (€210,000); (2) UK ISA with stocks and bonds worth £55,000 (€64,000); (3) UK savings account with £10,000 (€12,000); (4) Spanish apartment worth €300,000. His foreign assets exceed the threshold in Category II (pension + ISA = €274,000) and Category III (UK rental property he owns jointly, €120,000). James must file Modelo 720 declaring the pension (Category II), ISA (Category II), and UK rental (Category III). The UK savings account (€12,000) does NOT trigger Category I because it's below €50k. When James turns 75 and takes a pension drawdown, he'll have a massive withdrawal—still declared to Hacienda in his Spanish tax return (Modelo 100) as pension income. Modelo 720 declares the asset VALUE, not the income from it.
Sarah, a US expat in Barcelona, has: (1) 401k (US employer-sponsored retirement plan) worth $180,000 (€165,000); (2) Traditional IRA worth $80,000 (€73,000); (3) Roth IRA worth $65,000 (€60,000); (4) US brokerage account (stocks, ETFs) worth $150,000 (€137,000). Total foreign financial assets: €435,000. Sarah must file Modelo 720 declaring all four in Category II (investments and insurance policies). Note: The 401k is often overlooked because it's employer-held, but it's still an asset Sarah owns and must declare. US citizens abroad also file FBAR (Foreign Bank Accounts Report) with the IRS, a separate US filing, but Modelo 720 is Spain's requirement. The two filings are independent; compliance with one doesn't excuse the other. Additionally, if Sarah's 401k or IRA grows by more than €20,000 in a single year (market gains), she must refile Modelo 720 for that year.
Liam, Irish-born, moved to Spain for work in 2025. He owns: (1) UK buy-to-let property purchased for £220,000 (€255,000); (2) Irish occupational pension fund with €85,000 value. His foreign assets trigger Category III (real estate, €255,000) and Category II (pension, €85,000). He must file Modelo 720 declaring both. However, Liam's UK rental generates income (rent), which is declared separately in his Spanish income tax return (Modelo 100) as non-Spanish sourced income. The rental loss calculation, depreciation, and expenses are separate from the Modelo 720 asset declaration. Importantly, if Liam later sells the UK property for £250,000 (€290,000), he still files Modelo 720 for the year of sale, reporting the sale and proceeds—Hacienda wants to track if he's repatriating capital or investing it elsewhere.
Peter, Dutch, now Spanish-resident, is a beneficiary of a discretionary trust established in the UK 30 years ago. His beneficial interest in the trust assets (cash, securities, and UK real estate) totals approximately €480,000. Peter must declare his beneficiary interest in Category II (the beneficial interest is a financial right) and/or Category III if the trust holds real estate he has a right to. This scenario is complex because trust beneficial interests are tricky to value and require close coordination with a tax advisor familiar with trust law and Modelo 720. If Peter's interest increases by more than €20,000 (e.g., the trust distributes capital or revalues assets), he must refile.
Roberto, Argentine, qualified for Spain's Beckham Law (DNV regime) upon moving to Spain in 2025. He has existing foreign assets held before his Spanish residency: an Argentine real estate portfolio worth €550,000 and a US brokerage account worth €80,000. Under the Beckham Law exemption (for assets acquired PRE-residency), Roberto may be exempt from declaring these specific assets in Modelo 720—but the exemption is being narrowed, and guidance is complex. Critically, any NEW assets acquired AFTER obtaining Spanish residency must be declared. If Roberto buys a new US Treasury account in 2026, that new account (Category II) must be declared. Always consult a tax advisor if you're under the Beckham Law; this exemption is not automatic and requires strict documentation.
Emma, a British expat, moved to Spain in 2022 but never filed Modelo 720 in 2023, 2024, or 2025. She has a UK ISA (€65,000) and a US brokerage account (€120,000)—total €185,000, well above the threshold. In April 2026, Emma realizes she's non-compliant and immediately engages a tax advisor. Rather than waiting for an audit, the advisor files three years of Modelo 720 amendments (ampliaciones) covering 2023, 2024, and 2025, disclosing all assets. Because Emma filed voluntarily BEFORE Hacienda initiated an audit, penalties are reduced under post-ECJ proportionality guidelines. Instead of facing €10,000 × 3 years = €30,000 in maximum penalties, Emma's reduced penalties might be €2,000–€3,000 total for the three years. This scenario emphasizes the importance of swift voluntary disclosure.
Prior to 2022, Modelo 720 penalties were severe and often applied mechanically. Filing one day late incurred €1,000 minimum. Omitting even a single asset incurred €1,500 or more. Maximum penalties (€10,000) were common, even for expats unaware of the requirement. Thousands of UK and US expats in Spain faced harsh penalties simply for non-compliance caused by ignorance or moving logistics.
In December 2021, the European Court of Justice ruled (case C-788/19) that Spain's flat-rate Modelo 720 penalties were disproportionate and violated EU law principles of proportionality. The court found that penalizing procedural omissions (like missing a deadline) with the same severity as intentional tax evasion was excessive. Spain's legislature responded in 2022 with Law 5/2022, reforming the penalty regime.
Under the reformed regime, penalties are now scaled by severity and applied with flexibility:
Critically, if you discover non-compliance and file an amendment (ampliación) BEFORE Hacienda sends an audit notice or inspection letter, penalties are typically reduced by 50–75%. The tax authority views voluntary disclosure as showing good faith and compliance intent. Filing three years of late Modelo 720s voluntarily might incur €2,000–€3,000 total, whereas the same omission discovered by audit might incur €15,000–€20,000. This is why swift action if you realize you've missed filing is essential.
If you're a British expat and also subject to UK tax penalties (e.g., HMRC offshore penalties for non-disclosure), Spain and the UK double-taxation treaty (Spain-UK DTA) provides relief from double penalties. You can claim offset or reduction if you've paid penalties to one jurisdiction, avoiding punitive double-charging. Coordinate filings with a specialist familiar with both jurisdictions.
If you discover an omission or error BEFORE the tax authority contacts you, file an amendment (Modelo 720 ampliación) declaring the missing or incorrect assets. This is a new Modelo 720 form marked as a rectification/amendment, and it shows good faith. File the amendment as soon as possible; delays weaken your argument of good faith. Under post-ECJ practice, penalties for amended filings are typically reduced significantly or waived if you file early. If Hacienda contacts you first with an inspection letter, penalties are maximized and reduced penalties are harder to negotiate.
File amendments via the same electronic channel as the original (Agencia Tributaria website or via your tax representative). Clearly mark the form as an amendment (ampliación de declaración). Document your reason for the amendment: e.g., "Asset omitted due to account oversight," "New account opened in 2025," or "Asset valuation corrected."
Navigating Modelo 720 involves meticulous asset gathering, accurate valuation, and timely electronic filing. Our team of bar-registered solicitors and tax specialists guides you through each step:
We help you identify all foreign assets that trigger the €50,000 thresholds: bank accounts, investments, pensions, insurance policies, real estate, and crypto holdings. We request documentation from your financial institutions and prepare a comprehensive asset schedule to ensure nothing is missed.
We value each asset accurately as of 31 December using the correct methodology: market value for securities, surrender value for insurance, acquisition cost for real estate, and year-end balances for accounts. We apply the official exchange rate for foreign currency conversions and document all rates for audit compliance.
We prepare and electronically file your Modelo 720 with the Spanish tax authority using our registered digital credentials. We ensure all three asset categories are correctly populated, all thresholds are assessed, and the form is submitted before the 31 March deadline.
If you've missed filing prior years, we file voluntary amendments (ampliaciones) for each year, positioning your case for penalty reduction. We coordinate with Hacienda if necessary and negotiate reduced penalties based on good-faith late filing.
We amend prior-year Modelo 720 filings if errors are discovered: missing assets, incorrect valuations, or omitted categories. We file the amendments promptly and manage any tax authority correspondence.
For crypto holdings, we prepare and file Modelo 721 (crypto declaration) alongside your Modelo 720. If Wealth Tax applies in your region, we coordinate both filings to ensure completeness and avoid conflicts.
31 March is your deadline. Missing it exposes you to €1,000–€10,000 penalties, even if the omission was inadvertent. Our team ensures every asset is identified, accurately valued, and filed electronically before the deadline. We also manage voluntary disclosures for prior-year omissions, securing penalty relief through good-faith amendments. Let's get you compliant.
