Modelo 720 and Modelo 721: the foreign-asset declaration that catches new Spanish tax residents by surprise (2026 guide)

There is a Spanish tax form that costs you nothing and demands nothing — no payment, no rate, no allowance — and yet, for two decades, it terrified every foreign resident who heard of it. It is called Modelo 720, and it is the declaración informativa sobre bienes y derechos situados en el extranjero — the informational declaration of assets and rights held abroad.

For years the penalty schedule for filing late, filing incomplete, or filing wrong was so brutal (minimum €10,000 per omitted asset category, plus a 150% top-up on any "unjustified capital gain" the tax office chose to impute) that the European Court of Justice, in Case C-788/19 of 27 January 2022, tore the entire sanction regime apart and forced Spain to rewrite it under Ley 5/2022. The penalties are now proportionate. The obligation to file, however, is not going anywhere — and in 2023 it grew a sibling, Modelo 721, for crypto held on foreign platforms.

If you bought a Spanish property, moved in, and are still using your NatWest account, your Fidelity IRA, your Amsterdam apartment, or your Coinbase wallet exactly as you did before — this guide is for you. It is the return the gestor who filed your first Modelo 210 hands over the day you cross from non-resident to resident, and it is the return foreigners most often miss in year one of Spanish residency.

Non-resident vs resident — the fork that decides everything

Modelo 720 has one absolute prerequisite: you must be Spanish tax resident.

Non-residents (people who own a Spanish property but live abroad) never file it. They file Modelo 210 on their Spanish-source income and go home. Modelo 720 is exclusively a resident's obligation.

You are Spanish tax resident in a given year if any one of these is true:

• You spent more than 183 days in Spanish territory during the calendar year (sporadic absences count as presence unless you prove residence elsewhere).
• Your centre of economic interests — the bulk of your income, assets, or business activity — is in Spain.
• Your spouse and minor children habitually reside in Spain (a rebuttable presumption).

Two consequences most foreign property buyers underestimate:

1. Residency can start mid-year. If you moved into your Spanish house on 3 July, you were resident for 183+ days by 31 December. Your first Modelo 720 is due the following spring, covering every foreign asset you still held on 31 December.
2. There is no partial-year Modelo 720. The form is a snapshot: everything you owned abroad on 31 December, plus a look-back on assets closed during the year in some cases. What you owned on 4 January doesn't matter; what you owned on 31 December does.

If you are still non-resident, everything below is a preview — bookmark it for the year you cross the line, and stay on Modelo 210 until then.

What Modelo 720 actually is

Modelo 720 is informational. You pay no tax on it. It exists so the Agencia Tributaria (Spain's IRS, usually called Hacienda) can cross-reference the foreign wealth of Spanish residents against their income-tax returns, wealth-tax returns, and inheritance filings.

It captures three completely separate asset categories. Each category has its own €50,000 threshold, its own deadline logic, its own re-filing trigger, and its own line-by-line data schema.

Category 1: bank accounts abroad. Current accounts, savings accounts, term deposits, cash ISAs, money-market accounts, PayPal balances held at institutional level, foreign broker cash sweeps — anything where you have a right to withdraw cash held in a foreign financial institution. Reported by IBAN, BIC, holder(s), balance on 31 December, and average balance over the last quarter.

Category 2: securities, funds, insurance and annuities abroad. Stocks, bonds, mutual funds, ETFs, stock ISAs, US 401(k) and IRA balances, UK SIPPs, unit-linked policies, whole-life insurance with cash value, annuity contracts, employee share plans, foreign-domiciled corporate shares. Reported by ISIN or issuer identity, count/units, valuation on 31 December.

Category 3: real estate abroad. Any property (or right over property — usufruct, bare ownership, timeshare, multi-property) situated outside Spain in which you hold a stake. Reported by address, cadastral or land-registry reference (where one exists), acquisition date, and acquisition value.

You file whichever categories exceed the €50,000 threshold. If your foreign bank accounts total €48,000 and your foreign shares total €120,000, you file for Category 2 only. The form itself has three blocks; you fill in only the block(s) that apply.

The €50,000 threshold — the trap in one sentence

The threshold is €50,000 per category, aggregated across all assets in that category, and doubled for joint owners in exactly the wrong direction.

This last point is the one everyone gets wrong on their first go.

Suppose you and your spouse jointly own a UK current account with £75,000 (≈ €87,000) sitting in it. Common sense says the account is worth €87,000, split 50/50, so each of you holds €43,500 — below the threshold, nothing to file. Wrong. For Modelo 720 purposes, the balance to compare against the threshold is the full account balance, not your share. The joint account is a €87,000 asset in the account, above €50,000, so both spouses file, each declaring the full €87,000 balance and stating their percentage of ownership. Two returns. Two identical valuations. Zero tax due on either.

The same logic applies to jointly held brokerage accounts, jointly owned foreign homes, and joint life-insurance policies with two designated policyholders. The threshold looks at the asset; the return is filed by each owner.

Deadline calendar

Modelo 720 for a given tax year is filed between 1 January and 31 March of the following year. There is no extension. The form is filed electronically at the Agencia Tributaria portal, which requires either a certificado digital, Cl@ve PIN, or your gestor filing on your behalf via their professional certificate.

• Tax year 2025 → file between 1 January and 31 March 2026.
• Tax year 2026 → file between 1 January and 31 March 2027.

Compare with Modelo 210, which has the whole calendar year to file: Modelo 720 gives you three months, and the portal is chronically slow in the last two weeks of March. File in January or February.

When you have to re-file — the four triggers

The most misunderstood part of Modelo 720 is that after your first filing, you only file again in subsequent years if one of four things happens. If nothing changes materially, you don't touch it.

1. The value of any category rose by more than €20,000 compared with the last balance you declared for that category. Fifteen thousand euros of stock appreciation doesn't trigger a refile; €25,000 does.
2. You closed or fully disposed of an asset previously declared (sold the flat, closed the account, surrendered the policy). Even if the category total falls below €50,000, you refile to close out that specific asset.
3. You acquired a new asset in a category you had already declared, and it takes you back above the €20,000 threshold change from the last figure.
4. You crossed the €50,000 threshold in a category you had never declared before. New category, first filing.

In practice most owners refile every 2–3 years. Some file every year out of caution — no penalty for that, just work.

Modelo 721 — the crypto counterpart

In 2023 Spain added Modelo 721, a parallel informational return specifically for cryptocurrencies held on platforms located abroad. The trigger and deadline mirror Modelo 720:

• Threshold: aggregate crypto balance held on non-Spanish platforms exceeds €50,000 on 31 December, valued in euros at the year-end exchange rate.
• Deadline: 1 January – 31 March of the following year.
• Refile trigger: same €20,000 movement rule as Modelo 720.

Two important carve-outs:

• Self-custody wallets (Ledger, Trezor, MetaMask with private keys you hold) are not on Modelo 721, because there is no "foreign platform" to name. They may, however, appear on your Modelo 100 income return and on Modelo 714 wealth return.
• Crypto held on a Spanish-domiciled exchange (Bit2Me, for instance) is not on Modelo 721 — it's already visible to Hacienda through the domestic reporting regime.

If you moved to Spain with crypto sitting on Coinbase, Binance, or Kraken (all non-Spanish), you file Modelo 721 in your first resident spring. If those platforms' year-end euro value is below €50k, you don't — but note that a moderate bull run between filing years is exactly what triggers the €20k refile clause.

What actually goes on the form

Each asset row on Modelo 720 asks for the same skeleton of data:

• Asset type code (savings account, investment fund, real estate, etc.)
• Identifying reference (IBAN, ISIN, cadastral reference, policy number)
• Institution name and country
• Ownership percentage
• Type of ownership (holder, authorised signatory, beneficial owner, life-tenant, etc.)
• Acquisition date and value (for shares, funds and property)
• Year-end value in euros
• For Category 1: average balance over the fourth quarter

You need a euro conversion for anything held in another currency. Use the ECB reference rate at 31 December — the same rate the tax office uses to check your figures. Save a screenshot; two years later, when you refile, you will want to compare with the same source.

Penalties after the 2022 reform

Before Ley 5/2022, missing a Modelo 720 asset triggered:

• A flat €5,000 per missing data field, minimum €10,000 per omitted category
• An imputed "unjustified capital gain" equal to the entire asset value, taxed at your marginal rate
• A 150% additional penalty on that imputed gain
• No statute of limitations — the tax office could reach back forever

The CJEU ruled in January 2022 that all three of those elements together were disproportionate and violated the free movement of capital. Spain rewrote the regime in Ley 5/2022. Since 11 March 2022, missing or late Modelo 720 filings fall under the ordinary tax procedure:

• Voluntary late filing (before Hacienda writes to you): a surcharge of 1% per full month late, capped at 15% at 12 months, then 15% plus late-payment interest thereafter. Because there's no tax due on Modelo 720, the surcharge base is often €0 for late informational elements — but the fixed formal penalty of €150 to €250 still applies.
• After a Hacienda requirement: the penalty framework of Ley General Tributaria article 198 kicks in — up to €300 for an incomplete return, up to €1,500 for a late one after a requirement, and up to €600 per missing data set with material tax impact.
• Standard four-year statute of limitations applies again. If Hacienda has not opened proceedings within four years of the deadline, you are clear.

This is a completely different world from the pre-2022 regime. A first-time filer who missed year one and files voluntarily in year two is now looking at a formal penalty in the low hundreds, not the tens of thousands. But voluntariness matters: if you wait for a requirement letter, the numbers climb quickly, and if the tax office can show the omission was tied to undeclared income, the underlying income tax and full penalty regime attach separately.

The five foreign-buyer mistakes we see most

1. "I don't owe tax on it, so I don't need to declare it." Modelo 720 is informational — the whole point is that most people who file owe zero. The obligation attaches to the asset, not the tax.

2. "My UK ISA is tax-free, so it's exempt." Wrong on both counts. An ISA is a UK wrapper; Spain doesn't recognise it as tax-privileged (the growth is taxable on your Spanish return each year), and the wrapper itself is a Category 2 asset. Same for US Roth IRAs, French PEA, German Riester-Rente, and Dutch lijfrente products.

3. "I have €40k in three UK accounts, so I'm below the €50k threshold." The threshold is aggregate across the category. Three accounts of £15k each combine to £45k (≈ €52k) — above the threshold, all three declared.

4. "The house is my parents', they just put me on the deed." If you appear on the foreign land registry as a co-owner (even 1%), you file for it. Same for accounts on which you are an authorised signatory rather than the holder — signatory power over an account > €50k triggers Modelo 720 even if none of the money is yours.

5. "I filed once in 2019, nothing has changed, I'm fine." Nothing changed by more than €20,000 per category, and no asset was closed. If you sold one flat and bought another abroad in the same year, you refile — even if the net value is the same.

What to do if you missed a year

The 2022 reform makes this genuinely recoverable — but only if you move before the tax office moves.

Step 1. Reconstruct the missing year. Statements for the balance on 31 December, valuations for shares and funds at that date, the ECB EUR conversion rate, and the acquisition data for anything acquired that year.

Step 2. File the missing Modelo 720 as a declaración complementaria out of time (extemporánea sin requerimiento previo), through the normal portal. You mark the tax year that was missed; you do not file it against the current year.

Step 3. Expect a formal penalty letter of €150–€300 per omitted return. Pay it. Then file the current year on time.

Step 4. If you also had taxable income on those foreign assets (interest, dividends, rental income) that you didn't report on your Modelo 100 for that year, you need a separate complementaria of Modelo 100 as well. That one does carry a surcharge (1% per month, capped) on any tax that comes out of it. Do both filings together; the surcharge stops accruing the day you file voluntarily.

The single worst path is to leave both undeclared and wait — the four-year clock only starts when the return was originally due, and Hacienda's cross-reference with the Common Reporting Standard (foreign banks disclose Spanish residents automatically) is very good. Most foreign owners who get caught, get caught because their UK or German bank routinely reports them to Madrid.

Do you need a gestor for this?

For the first ever Modelo 720, yes — almost always. The data schema is fiddly, the ISIN look-ups are painful, the ECB rate has to be applied consistently, and the joint-ownership rules bite anyone doing it alone. Expect €200–€500 for a first-year return with a normal portfolio (one country, two-three accounts, one house), €600–€1,200 if you have multiple countries and structured products.

For refiles in years 2, 3 and 4, once the template is set up, you can either:

• Keep the gestor for €80–€150 a year and never think about it, or
• Switch to a specialist online service (a few Spanish fiscal firms now offer flat-fee Modelo 720 subscriptions), or
• Do it yourself through the Agencia Tributaria portal with your certificado digital, using last year's return as the template.

Doing it yourself works for simple portfolios and stable balances. It falls apart the year you also file Modelo 721 for the first time, or the year you sell a foreign property (which touches Modelo 100, wealth tax, and Modelo 720 simultaneously). Pay a specialist for the year you have a life event; DIY the quiet years.

How Modelo 720 fits with the rest of the resident tax stack

Modelo 720 does not replace anything. It sits alongside:

• Modelo 100 — your annual resident income return, filed each April/June, on which the income from those foreign assets (dividends, interest, rental income, distributions from foreign pensions) is taxed.
• Modelo 714 — the resident wealth-tax return, filed each April/June if your worldwide net assets (Spanish and foreign) exceed the autonomous-community threshold. Modelo 720 gives Hacienda the values to check your Modelo 714 numbers against.
• Modelo 718 — the temporary solidarity tax on large fortunes, applicable above €3M in worldwide net wealth.

The purpose of Modelo 720 is precisely to close the loop: it tells the tax office what you own, so that the other three returns can be verified against it. Filing an accurate Modelo 720 and then omitting foreign dividends from Modelo 100 is a straightforward way to get selected for review. Filing them consistently across all four is boring, safe, and cheap.

The 2026 outlook

Two threads to watch this year:

• The DAC7/CRS crackdown. Spain has been ramping up automatic exchange-of-information queries to foreign banks and platforms, especially for residents who signed a Spanish empadronamiento within the last three years. Expect proactive letters where the foreign data conflicts with a missing Modelo 720.
• A push to unify Modelo 720 and Modelo 721. A consultation opened in mid-2025 suggests a single form with a crypto block by 2027. If it happens, existing filers will migrate — no back-filing required.

Neither changes the obligation, only the paperwork.

What to do next

If you bought a Spanish property this year and are on track to cross 183 days by 31 December, make a list now of every foreign account, brokerage, insurance policy, pension, foreign home and crypto platform in your name — plus your spouse's — with the year-end value in euros. You'll thank yourself in February when the gestor asks. If you are not sure whether this year counts as your first resident year, ask before December — the decision drives whether Modelo 720 is due in three months or fifteen.

If you have been living in Spain for years and never heard of Modelo 720 until today, that is fixable. The post-2022 penalty regime is proportionate, the CRS data lag gives you a window, and a voluntary catch-up filing is dramatically cheaper than the letter that eventually arrives. Any Spanish asesor fiscal handles this weekly.

And if you are still shopping — before your NIE, before your arras, before Spain becomes your tax home — the time to plan around Modelo 720 is before the purchase completes. Whether you buy through a Spanish SL, split ownership with your spouse, or restructure a foreign pension into something Spain treats more kindly, the moves that matter are pre-completion moves. Post your criteria on Buvivo and let the agents who understand foreign-buyer tax structures come to you — that framing alone tends to filter out the ones who don't.
