Modelo 720 Deadline for Americans in Spain: 2026 Filing Guide
The Modelo 720 is Spain's declaration of assets held outside Spain, and it is due by March 31 each year for the prior calendar year. Spanish tax residents, including Americans living in Spain, must file it if any of three asset categories exceeds 50,000 euros. It is an information return, not a tax, but Spain treats it seriously.
This article is general education, not tax or legal advice. Verify every point against current Agencia Tributaria (Spanish Tax Agency) guidance and the BOE, and consult a qualified cross-border professional for your situation.
What the Modelo 720 Is
The Modelo 720 (Declaracion sobre bienes y derechos situados en el extranjero) is an informational declaration that Spanish tax residents use to report assets and rights located abroad. It reports the existence and value of foreign assets; it does not itself levy a tax.
Spain introduced the form to improve visibility into residents' overseas holdings. For an American who becomes a Spanish tax resident, this means your US bank accounts, US brokerage accounts, US real estate, and similar foreign-held assets can become reportable to Spain, entirely separately from your US FBAR and FATCA obligations. The Modelo 720 is the Spanish counterpart concept, but it is a distinct filing with its own rules, thresholds, and deadline.
Who Must File: The Tax Residency Trigger
The obligation attaches to Spanish tax residents, not to visa holders as such. Understanding when you become a tax resident is the first step.
You are generally a Spanish tax resident if you spend more than 183 days in Spain in a calendar year, or if your center of economic interests is in Spain. Once you are a tax resident, your foreign assets come within the scope of the Modelo 720. This is why Americans on the Non-Lucrative Visa and the Digital Nomad Visa both need to think about it: living in Spain long enough to be a resident is exactly what these visas facilitate. Note that people taxed under Spain's Beckham Law regime may be treated differently for this purpose, which is one of that regime's practical advantages; confirm the current treatment for your case.
The Three Asset Categories and the 50,000 Euro Threshold
The Modelo 720 divides foreign assets into three categories, and the 50,000 euro threshold is applied to each category separately, not to your total foreign wealth. This category-by-category structure is central to getting the filing right.
The three categories are:
- Accounts held with financial institutions abroad (bank and similar accounts).
- Securities, rights, insurance, and income deposited or managed abroad (including brokerage holdings, shares, and certain insurance and annuity products).
- Real estate and rights over real estate located abroad.
You must report a category if the total value of assets in that category exceeds 50,000 euros. You could have 45,000 euros in foreign accounts and 60,000 euros in foreign securities: the accounts category falls below the line and is not reportable, while the securities category exceeds it and must be declared. Verify the current category definitions with the Agencia Tributaria.
The March 31 Deadline
The Modelo 720 is filed between January 1 and March 31 for the immediately preceding calendar year. The March 31 deadline is the fixed point to plan around.
The form is filed electronically through the Agencia Tributaria's online portal, which generally requires a digital certificate or the Cl@ve identification system. Because the deadline sits earlier than many US tax dates, Americans juggling both systems should not assume the Spanish filing can wait until they handle their US returns in June. Put March 31 on the calendar independently, and confirm the exact current-year date with the Agencia Tributaria, since procedural details can change.
When You Have to File Again in Later Years
A common misunderstanding is that the Modelo 720 must be re-filed in full every year. In most cases it does not, and knowing the re-filing triggers avoids unnecessary work and unnecessary risk.
After your first declaration, you generally must file again in a later year only when:
- The value of a previously reported category increased by more than 20,000 euros over the last reported figure, or
- You closed an account or sold an asset that you had previously reported, or
- You acquired new assets that push a category over the 50,000 euro threshold for the first time.
If none of these apply, you typically do not re-file for that year. This is why keeping a clear record of what you reported, and at what value, matters: you need last year's figures to judge whether this year crosses a re-filing trigger. Confirm the current re-filing rules with the Agencia Tributaria.
How the Penalty Regime Changed
The Modelo 720 became notorious for extraordinarily harsh penalties, and those penalties were the subject of a significant legal challenge. Americans researching older articles will find alarming figures that no longer fully apply, so the current position matters.
In 2022, the Court of Justice of the European Union (CJEU) ruled that key parts of Spain's Modelo 720 penalty regime were disproportionate and contrary to EU law, particularly the treatment of unreported foreign assets as unjustified capital gains without a statute of limitations, and the scale of the associated fines. In response, Spain revised the penalty framework to bring it into line with ordinary rules for information-return failures. The obligation to file did not disappear; what changed is that the penalties for getting it wrong are no longer the disproportionate amounts that made the form infamous. Because this area has moved and could continue to evolve, verify the current penalty rules against up-to-date Agencia Tributaria and BOE sources rather than relying on pre-2022 descriptions.
Modelo 720 Versus US FBAR and FATCA: Keep Them Separate
Americans in Spain often assume that filing their US foreign-account forms covers their Spanish reporting, or vice versa. They are entirely separate obligations to two different governments, and both can apply at once.
| Feature | Modelo 720 | FBAR (FinCEN 114) | FATCA (Form 8938) |
|---|---|---|---|
| Filed with | Spain (Agencia Tributaria) | US (FinCEN) | US (IRS, with 1040) |
| Threshold | 50,000 euros per category | 10,000 USD aggregate | Higher, varies abroad |
| Reports | Assets outside Spain | Accounts outside US | Assets outside US |
| Deadline | March 31 | April 15 (auto to Oct 15) | With tax return |
For a US citizen resident in Spain, the mirror image is striking: your US assets are foreign to Spain and reportable on the Modelo 720, while your Spanish assets are foreign to the US and reportable on the FBAR. Filing one does nothing for the other. See our FBAR guide and Form 1040 guide for the US side, and note that both systems can require reporting the same underlying accounts to different authorities.
Practical Steps to Stay Compliant
Compliance is mostly organization. Because the form is category-based and re-filing depends on changes from prior years, good records make the annual decision simple.
- Inventory your foreign assets by category: accounts, securities and insurance, and real estate.
- Value each category to see which ones exceed 50,000 euros.
- Keep a record of what you reported and at what value, for judging future re-filing triggers.
- File by March 31 through the Agencia Tributaria portal, using a digital certificate or Cl@ve.
- Coordinate with your US filings but never assume one substitutes for the other.
Americans should map this out in their first year of Spanish tax residency, because the first Modelo 720 often coincides with the year they also start Spanish income tax filing.
US Retirement Accounts: A Frequent Point of Confusion
For Americans, one category causes more questions than any other: US retirement accounts such as 401(k)s and IRAs. Whether and how they appear on the Modelo 720 is a recurring source of uncertainty.
These accounts are financial assets held outside Spain, so they fall within the general scope of the securities-and-rights category, and their value counts toward that category's 50,000 euro threshold. The complication is that US retirement accounts also raise questions about how Spain treats them for income tax when you draw on them, which is a separate issue from the informational reporting. Because the interaction between US retirement vehicles and the Spanish system is genuinely intricate, and because getting the reporting and the eventual taxation right can materially affect retirees, this is an area to review carefully with a cross-border professional rather than to guess at. Confirm the current treatment with the Agencia Tributaria and a qualified adviser.
Coordinating the Modelo 720 With Your Spanish Income Tax
The Modelo 720 does not exist in isolation; it sits alongside your annual Spanish income tax return, and the two should tell a consistent story. Reviewers can compare what you report as assets with what you report as income.
If you declare foreign accounts and securities on the Modelo 720, Spain reasonably expects any income those assets generate, interest, dividends, rental income, to appear on your annual IRPF return (declaracion de la renta). A mismatch, such as substantial reported foreign holdings but no corresponding foreign income, can invite questions. The practical takeaway is to treat the Modelo 720 and your income tax filing as parts of one coherent picture, prepared together, so that your asset disclosures and your income disclosures are consistent. This coordination is easier when you plan both filings at the start of your first year as a Spanish tax resident.
The Bottom Line
The Modelo 720 is Spain's foreign-asset information return, due March 31, required of Spanish tax residents whose assets in any of three categories exceed 50,000 euros. It carries no tax of its own, its once-notorious penalties were reined in after the 2022 CJEU ruling, and it is completely separate from the US FBAR and FATCA. For Americans, the practical reality is that your US accounts and property may be reportable to Spain, just as your Spanish accounts are reportable to the US.
As of July 2026, this is general education and not tax or legal advice. Confirm the deadline, thresholds, re-filing triggers, and current penalty rules against Agencia Tributaria guidance and the BOE, and work with a qualified cross-border professional.
