Modelo 720 in Spain: Who Files, When, and What it Now Costs to Miss
If you're a Spanish tax resident with more than 50,000 EUR sitting in foreign banks, brokerages, or property, Modelo 720 is the form that puts those assets on the AEAT's radar. Here's the 2026 version of the guide we wish we had handed every client on day one in Valencia.
Heads up: The 2026 filing window closed on 31 March. If your foreign assets were above the threshold on 31 December last year and you missed the deadline, do not pretend it didn't happen. Read the penalties section below and contact a Spanish tax lawyer the same week. The next window opens on 1 January for assets held at the previous year end.
Who Must File the Modelo 720
Modelo 720 is a residency-driven obligation, not a citizenship one. If you crossed the 183-day line in Spain last year, or your center of vital interests is here, you are a Spanish tax resident and you owe this declaration the moment any single asset category abroad clears the 50,000 EUR mark. Many of the people I sit down with in Valencia don't realise their UK ISA, Belgian Argenta account, or US Vanguard portfolio all live in scope.
Spanish tax residents
Anyone resident in Spain for tax purposes - the 183-day rule, your spouse and minor children living here, or your main economic activity based in Spain. Nationality is irrelevant. A Beckham Law resident is still a tax resident; check the Beckham regime page for the wealth-tax carve-out that does not extend to Modelo 720.
Owners, authorized signatories, or beneficial owners
You report assets you own outright, accounts where you are a signatory or have power of disposal (think company bank accounts where you have access), and assets where you are the beneficial owner via a foreign structure. The AEAT casts a wide net here.
Anyone hitting the 50,000 EUR threshold in any one category
The threshold is per-category, not aggregate. 40,000 EUR in foreign bank accounts plus 40,000 EUR in foreign brokerage plus 40,000 EUR in foreign property means you do not file - none of the categories crossed 50,000 EUR on its own. But 51,000 EUR sitting in a single Bunq account triggers the whole form.
Returning filers above the 20,000 EUR growth line
Once you have filed Modelo 720 once, you only re-file in a future year if any category grows by more than 20,000 EUR versus the last declaration, or if you closed accounts you previously reported. Stable holdings between 50,000 and 70,000 EUR after a first filing mean no annual repeat - a quiet relief most newcomers miss.
What Counts as a Reportable Foreign Asset
The form splits foreign assets into three named blocks. Each has its own 50,000 EUR threshold, applied independently. You report year-end balances (31 December) plus, for accounts, the average balance over the last quarter. The single biggest mistake newcomers make is forgetting that a non-Spanish bank account held jointly with a parent or sibling still counts in full, not by share.
Bank accounts abroad
Any current account, savings account, or fixed-term deposit held outside Spain - Bunq, Wise, Revolut EU, Argenta, HSBC UK, Chase US. Joint accounts are reported at their full value plus a note of the ownership share. You list each IBAN, bank, opening date, and year-end balance.
Securities, funds, life insurance, pensions
Shares, ETFs, mutual funds, bonds, fund units, and life-insurance policies with cash value held at a non-Spanish institution. Brokerage accounts with Interactive Brokers Ireland, US 401(k) and IRA balances, UK SIPP and ISA, French PEA, Belgian effectenrekening. Pensions are nuanced - check with a fiscal expert if your scheme has no individual capitalization.
Real estate and property rights abroad
Any property outside Spain with an acquisition value above 50,000 EUR - the family flat in Brussels, a holiday apartment in Lisbon, a US rental. You also report usufruct rights, timeshares, and any partial ownership. Acquisition value and purchase date are what get filed, not current market value.
Why this matters: the threshold is per category. A Modelo 720 obligation can sneak up on someone with a perfectly modest UK ISA combined with a parent's Belgian account they co-signed years ago. If you are unsure, list everything on a spreadsheet before you decide.
The Filing Window and the 2026 Calendar
Modelo 720 is an annual filing that reports the state of your foreign assets as of 31 December of the previous year. The window is fixed and short. There is no extension, no installment, no payment due - it's purely informative, but the absence of a tax bill makes people complacent. Filing late, even by one day, can still trigger penalties under the post-2022 regime.
Window opens
1 January 2026
Window closes
31 March 2026
Next window
1 Jan to 31 Mar (every year)
You file electronically through the AEAT portal with your digital certificate, Cl@ve PIN, or via a fiscal representative. Most of our Valencia clients who don't already have a tax adviser use their gestorÃa - the form is dense, the codes are unforgiving, and the audit trail matters if AEAT ever pings you. If you are filing for the first time and have multiple foreign brokerage accounts, budget at least a half-day to gather statements, average balances, and ISIN codes.
Penalties After the ECJ Ruling
This is the section where the news is genuinely better than it used to be. The European Court of Justice ruled in January 2022 that the original Modelo 720 penalty regime - 5,000 EUR per data point, no proportionality, plus the assumption of unjustified capital gain on un-declared assets with no statute of limitations - was incompatible with EU law. Spain rewrote the regime in Law 5/2022 (passed July 2022) to bring penalties in line with the general tax-penalty code. Old numbers you may still read online no longer apply.
| What | Before (struck down) | After Law 5/2022 (in force 2026) |
|---|---|---|
| Missing or incomplete data points | 5,000 EUR per data point, 10,000 EUR minimum | 150 EUR per data point, 1,500 EUR minimum (general tax-info penalties) |
| Late filing (no AEAT request first) | 100 EUR per data point, 1,500 EUR minimum | 20 EUR per data point, 300 EUR minimum, capped |
| Unjustified capital gain on un-declared assets | 150% of the income tax on the imputed gain, no time limit | Standard 4-year statute of limitations applies; penalty 50-150% of unpaid tax following normal rules |
| Criminal exposure | Theoretical under fraud rules | Same threshold as any tax fraud (120,000 EUR of evaded tax) - the standalone Modelo 720 criminal trigger is gone |
What this means practically: filing late or with an error is no longer an existential financial event for a normal expat. It is still expensive enough to be worth avoiding. If you missed a previous year and the AEAT has not contacted you, voluntary disclosure now (extemporanea) is almost always cheaper than waiting for them to find you. A Spanish tax lawyer should run the numbers before you act.
Modelo 720 vs Modelo 721 (the New Crypto Form)
From the 2023 tax year onward, Spain introduced Modelo 721 as a separate, crypto-specific equivalent of Modelo 720. They share the calendar (1 January to 31 March) and the 50,000 EUR threshold, but the assets they cover do not overlap. If you hold crypto on a non-Spanish exchange or in a self-custody wallet abroad, you file Modelo 721 - not 720 - on those holdings. If you have both fiat assets abroad and crypto abroad above the threshold, you file both forms.
Modelo 720
Bank accounts, securities, real estate
The original form, covering the three traditional asset categories held outside Spain. No crypto. Same 50,000 EUR per-category threshold, same window, same penalty regime since Law 5/2022.
Modelo 721
Crypto assets held abroad
Specifically covers virtual currencies held with a non-Spanish custodian or in a self-managed wallet abroad. Same 50,000 EUR threshold per holding. Same 1 January to 31 March window. Penalties follow the same post-Law 5/2022 framework.
