Modelo 720 for US retirees in Spain

Modelo 720 is one of the forms American retirees hear about late, usually after they have already moved. That is a mistake. The form is not an income tax return and it does not, by itself, create a Spanish tax charge. It is an information return telling the Spanish Tax Agency what foreign assets a Spanish tax resident holds outside Spain. For a US retiree, "foreign" means the assets you naturally left behind in the United States: checking accounts, savings accounts, brokerage portfolios, 401(k)s, IRAs, Roth IRAs, annuities, life insurance cash value, a vacation home, rental property, or a share in a family account.

This page sits next to our guides on how US retirement income is taxed in Spain, US tax filing obligations for American retirees and US banking, FATCA and FBAR. The difference is simple: those pages ask how income is taxed or reported in the United States. Modelo 720 asks what assets Spain wants to know about once you are a Spanish tax resident. It is general orientation only, not tax advice, and US retirement wrappers require Spanish classification by a qualified adviser.

"Modelo 720 is not about paying tax on the asset. It is about Spain knowing what foreign assets a resident holds. For US retirees, the hard part is rarely one bank account. It is the mix: brokerage, IRA, Roth, pension product, property and US reporting all using different names for the same wealth."

Who has to think about Modelo 720?

The starting point is Spanish tax residence, not nationality and not the name of your visa. A US citizen with a non-lucrative visa can become Spanish tax resident if they spend more than 183 days in Spain during a calendar year or if Spain becomes their main centre of economic interests. Once that happens, Spain taxes worldwide income and also asks for information about certain foreign assets. A person who has only just received a visa but has not become Spanish tax resident yet is in a different position.

For retirees this creates a timing issue. You may arrive in Spain in spring, settle into a rented home, apply for your TIE and live quietly. Months later, the first reporting season arrives. If you crossed into Spanish tax residence during that calendar year, the next 1 January to 31 March window can matter. The right planning question is therefore not "am I American?" but "for which calendar year did I become Spanish tax resident, and what foreign assets did I hold at 31 December of that year?"

One warning about the number itself, because we have watched it cause real confusion. The United States also has a Form 720 — the Quarterly Federal Excise Tax Return — and it has nothing whatever to do with this one. Same three digits, different country, different purpose, no relationship. It is not a hypothetical collision for a retiree in Spain: the US Form 720 is where the excise tax on premiums paid to a foreign insurer is reported, which is exactly what an American who buys a Spanish life annuity to claim the over-65 exemption may walk into. If anyone tells you there is "a 720" to deal with, establish which country they mean before you file anything.

The three main asset categories

Modelo 720 is organised around categories, and this matters because the thresholds are applied by category. In practice the three categories most relevant to American retirees are: foreign bank accounts; foreign securities, rights, insurance and annuity-type assets; and foreign real estate or rights over real estate. Spain looks at assets outside Spain, so ordinary US accounts and US property are foreign assets from the Spanish perspective.

Category	US retiree examples	Common trap
Bank accounts	US checking, savings, CDs, joint accounts where you are holder or authorised	Thinking a dormant or old account is irrelevant
Securities, rights, insurance	Brokerage portfolios, shares, ETFs, bonds, annuities, life insurance cash value, some retirement wrappers	Assuming US retirement accounts are invisible because they are tax-favoured in the US
Real estate	US home retained after moving, rental property, inherited property interest	Forgetting a partial or jointly owned interest

The category labels are Spanish tax labels, not US marketing labels. A "brokerage account", a "traditional IRA", a "Roth IRA", a "401(k)" and an "annuity" can each require a separate classification exercise. The important work is to map each asset to the Spanish category before filing, using documents that show holder, value, date and currency.

The 50,000 euro and 20,000 euro rules

The practical threshold most clients hear is 50,000 euros. It is not a single worldwide-assets threshold. It is applied by category. If the value in a relevant category exceeds 50,000 euros, that category can become reportable. A retiree with 35,000 euros in US bank accounts and 300,000 euros in a US brokerage account is not looking at one combined 335,000 euro test; the bank category and the securities category are tested in their own way. The same is true for US real estate.

After you have filed for a category, Modelo 720 is not necessarily filed every year for the same assets. In general, a later filing is required again where the value of a previously reported category increases by more than 20,000 euros, or where certain reported assets are sold, cancelled, closed or otherwise cease to be held. That second point catches people who think only growth matters. Closing a US account, selling a US home, transferring securities or changing ownership can be a reporting event even if you do not feel wealthier.

How US assets usually enter the analysis

American retirees typically have a more complex Modelo 720 file than European retirees because the US system uses many account wrappers. A simple checking account is easy. A joint savings account requires attention to ownership and authorisation. A taxable brokerage account may involve securities, cash and sometimes money-market positions. A traditional IRA, Roth IRA, 401(k), 529 college plan or HSA raises a classification question: what exactly does the Spanish form see, an account, securities, rights, insurance-type product or something else? The answer should not be guessed from US labels.

Watch for the transactions that move an asset from one of those wrappers into another, because they can quietly settle a classification question you were still arguing. The clearest example is a distribution of employer stock out of a 401(k) under the US NUA rules: the shares go from inside a plan, where their reporting treatment is genuinely contestable, into a taxable brokerage account, where listed foreign securities held abroad are not contestable at all.

Two related mistakes are worth naming because they are easy to make in good faith. The first is omission: Series EE and I savings bonds produce no statements and no annual 1099, so the assets people most often leave off the form entirely are the ones sitting silently in a drawer. The second is valuation. These bonds are reportable at redemption value, not at the amount printed on the front — a bond with $5,000 on its face may be worth several times that after decades of accrued interest, so using the printed number files an inaccurate return while feeling like compliance.

Real estate is another common issue. If you keep your US home after moving to Spain, it may be relevant for Modelo 720 even if it produces no rental income and even if you plan to sell later. If you keep a US rental property, the reporting issue is separate from the income-tax issue. The property can be reportable as an asset, and the rent or sale gain can separately appear on your Spanish income tax return. A family cabin, inherited fractional interest or property held with siblings should be reviewed, because small ownership percentages can still create Spanish reporting work. A US timeshare belongs in the same classification exercise: a deeded week may be a right over foreign real estate, while a points or club product may need a different analysis.

Crypto is different. The Spanish Tax Agency states that virtual currencies are not reported on Modelo 720; foreign-held virtual currency has its own information return, Modelo 721. For retirees this may be less common than for founders, but many Americans hold crypto through exchanges or wallets. If that is your case, do not fold it into Modelo 720 without checking Modelo 721 separately.

The filing calendar

The ordinary filing window is from 1 January to 31 March following the calendar year being reported. The Spanish Tax Agency published the Modelo 720 filing window for the 2025 return as 1 January to 31 March 2026. That means an American who became Spanish tax resident during 2025 and held reportable US assets at 31 December 2025 would normally be looking at that first-quarter 2026 filing season.

This calendar does not match the US tax calendar in a neat way. US citizens abroad still have US filing obligations, often with automatic extensions and separate FBAR timing. Spain's personal income tax return is generally filed later in the spring and early summer. Modelo 720 comes earlier. That is why the asset list should be prepared before the year closes, not when the renta campaign is already underway.

Modelo 720 vs FBAR and Form 8938

Modelo 720 does not replace FBAR or Form 8938. They belong to different countries and ask different questions. FBAR is a US Treasury report for foreign financial accounts, meaning accounts outside the United States from the US perspective. Modelo 720 is a Spanish report for assets outside Spain. A US checking account is domestic for FBAR purposes but foreign for Modelo 720. A Spanish bank account is foreign for FBAR purposes but domestic for Modelo 720. That mirror-image problem is one reason Americans in Spain need both sides coordinated.

Form 8938 is also separate. It is filed with the US tax return by specified individuals with certain foreign financial assets, and how it compares with the FBAR, and why a retiree often files both, is a question in its own right. Its thresholds and definitions are not the same as Modelo 720. Do not assume that if a US preparer said "no 8938 this year", Spain also has no reporting form. Equally, a Spanish adviser preparing Modelo 720 may not be covering FBAR — nor the receipt-side US report that a foreign gift or inheritance can trigger on Form 3520, which is a separate filing again. The safest workflow is a shared asset inventory used by both advisers, then translated into each country's forms.

Penalties after the EU challenge

Modelo 720 has a reputation for harsh penalties because Spain's original regime was challenged before the Court of Justice of the European Union. In January 2022 the court held that important parts of the old penalty system breached EU law, and Spain amended the regime afterwards. That history matters because many articles online still repeat the old fear language without explaining the change.

The practical conclusion is balanced: the form is not the monster some outdated commentary describes, but it is still a real tax-compliance obligation. Late, inaccurate or missing filings can still create penalties under Spain's general tax rules, and the existence of the EU judgment is not a reason to ignore the form. Treat it like any other annual compliance item: identify the duty early, document the values, file when required and keep evidence.

Practical checklist before you move

Before becoming Spanish tax resident, make a clean inventory of assets outside Spain. For each item, record the institution, account number or property reference, holder, percentage ownership, country, currency, year-end value and whether the asset was opened, closed, transferred, sold or newly acquired during the year. For accounts and portfolios, keep December statements. For real estate, keep acquisition documents and a defensible valuation basis. For retirement accounts, gather plan statements and product descriptions so your Spanish adviser can classify them rather than infer from a nickname.

Then align the inventory with the rest of your move. If you are applying for the non-lucrative visa, the same financial picture often appears in your visa evidence, Spanish tax-residence planning, US filing, FBAR/Form 8938 review and Modelo 720 analysis. The facts should be consistent across all of them. We help clients keep that sequence in order: immigration timeline first, tax residence year, asset inventory, reporting calendar and adviser handoff.
