FATCA and FBAR for US Citizens Owning Property in Spain: What You Must Report

Buying a property in Spain doesn’t just create Spanish tax obligations — it can also trigger US federal reporting requirements that many American buyers overlook until it’s too late.

By Paton & Mayr · October 2026 · 9 min read

Every year, US citizens who own property abroad face questions their Spanish neighbours never have to think about. FATCA (the Foreign Account Tax Compliance Act) and FBAR (the Report of Foreign Bank and Financial Accounts) are two separate US reporting obligations that can apply when you own real estate in Spain — and the penalties for missing them can be severe.

This guide explains what each obligation covers, when owning Spanish property triggers a filing requirement, how to calculate the relevant thresholds, and what happens if you don’t comply. It is intended as an educational overview; specific reporting decisions should always be made with a qualified US tax adviser.

At Paton & Mayr, we work alongside US tax professionals to ensure our American clients have a complete picture of their obligations before — and after — they complete a purchase in Spain. Our property tax advice for Americans in Spain is designed to bridge both jurisdictions.

What Is FBAR — and Does Owning Spanish Property Trigger It?

FBAR stands for the Report of Foreign Bank and Financial Accounts, filed annually on FinCEN Form 114. It is administered by the US Treasury’s Financial Crimes Enforcement Network (FinCEN), not the IRS.

Who must file: Any US person (citizen, resident, certain visa holders) who has a financial interest in — or signature authority over — one or more foreign financial accounts whose aggregate maximum value exceeded $10,000 at any point during the calendar year.

Does real estate itself trigger FBAR?

Directly held real estate — a Spanish apartment or villa in your personal name — is not itself a «foreign financial account» and does not trigger FBAR filing on its own. The property is an asset, not an account.

However, owning Spanish property almost always creates FBAR exposure indirectly:

  • Spanish bank account for expenses. Most buyers open a Spanish current account to pay utility bills, community fees, and IBI (local property tax). If this account holds more than $10,000 at any point in the year, FBAR applies.
  • Rental income accounts. If you let your Spanish property and receive rent into a Spanish account, that balance counts toward the threshold.
  • Property held through a legal entity. If you own a Spanish sociedad limitada (SL) or other foreign entity that holds the property, you may have FBAR obligations with respect to the entity’s accounts.
  • Mortgage escrow accounts. Some Spanish mortgage structures involve accounts held in your name during the purchase process.

The $10,000 threshold is an aggregate across all foreign accounts combined — not per account. A buyer with three Spanish accounts each holding $4,000 still has a filing obligation.

FBAR deadline: FinCEN Form 114 is due on 15 April each year, with an automatic extension to 15 October. It is filed electronically through the BSA E-Filing System — not with your tax return. Late or missed filings can result in penalties of up to $10,000 per violation for non-wilful failures, and up to the greater of $100,000 or 50% of the account balance per violation for wilful failures.

What Is FATCA — and How Does It Relate to Spanish Property?

FATCA — the Foreign Account Tax Compliance Act — was enacted in 2010 and requires US taxpayers to report specified foreign financial assets on IRS Form 8938, which is attached to the annual tax return (Form 1040). Unlike FBAR, Form 8938 is an IRS form, not a FinCEN form.

FATCA’s scope is broader than FBAR: it covers not only foreign bank accounts but also other «specified foreign financial assets», including:

  • Foreign bank and investment accounts
  • Stock or securities issued by foreign entities
  • Financial interests in foreign entities (e.g. a Spanish SL that holds property)
  • Foreign partnership interests and certain contracts with foreign counterparties

FATCA thresholds for US residents abroad

Thresholds vary depending on where you live and your filing status. For US taxpayers living abroad — which includes many Americans with Spanish property as a primary or secondary residence — the thresholds are significantly higher:

Single filer (abroad)

$200,000

Last day of year; or $300,000 if exceeded at any point during the year

Married filing jointly (abroad)

$400,000

Last day of year; or $600,000 if exceeded at any point during the year

For taxpayers living in the US, the thresholds are lower ($50,000/$75,000 single; $100,000/$150,000 married filing jointly). Many American buyers who maintain their US residence but own a Spanish holiday home will fall under the US-resident thresholds.

Does the property itself count for FATCA?

Again, directly held real estate is generally excluded from FATCA reporting — the property itself is not a «specified foreign financial asset.» However, the following do count:

  • Any Spanish financial accounts (current accounts, savings accounts, mortgage offset accounts)
  • A Spanish SL or other foreign entity through which you hold the property (your interest in the entity)
  • Foreign investment products linked to the purchase (certain insurance policies, pension products)

FATCA penalties: Failure to file Form 8938 can result in a penalty of $10,000 per year, rising to $50,000 if the failure continues after IRS notification. There is no separate criminal penalty for Form 8938 failures — but the IRS can use FATCA information to pursue other enforcement action.

FBAR vs FATCA: Key Differences at a Glance

Many US property owners confuse FBAR and FATCA because both involve reporting foreign assets. They are separate obligations with different thresholds, different forms, and different agencies. You may be required to file both, neither, or one but not the other.

FBAR (FinCEN 114) FATCA (Form 8938)
Administered by FinCEN (Treasury) IRS
Form FinCEN 114 (online only) IRS Form 8938 (with 1040)
Threshold (foreign accts) $10,000 aggregate $200,000–$600,000 (abroad)
Covers real estate directly? No No (but entity interests yes)
Penalty (non-wilful) Up to $10,000/year $10,000/year
Statute of limitations 6 years 3 years (6 if omission > $5,000)

Filing one does not satisfy the other. If you meet the threshold for both, you must file both — separately, on different forms, to different agencies.

Don’t Forget the Spanish Side: Modelo 720

While FBAR and FATCA are US obligations, Spain has its own asset-declaration requirement: Modelo 720, the annual declaration of overseas assets held by Spanish tax residents. If you live in Spain — or have established Spanish tax residency — you must declare foreign bank accounts, real estate, and investments held outside Spain when these exceed €50,000 per category.

For an American who has become a Spanish tax resident, this means potentially filing:

  • FBAR — for Spanish accounts
  • Form 8938 — for Spanish financial assets above the FATCA threshold
  • Modelo 720 — for US accounts, US real estate, and other foreign assets above the Spanish threshold
  • Form 1040 + FEIE or FTC — to manage double taxation with Spain’s income tax (IRPF)

The interaction between these obligations requires co-ordination between a US CPA (ideally one specialising in expat taxation) and a Spanish gestor or tax lawyer. Our team can help connect you with appropriate advisers on both sides.

Penalties for Non-Compliance — and How to Come Back Into Compliance

The most common compliance problems we see among American buyers in Spain are:

  • Opening a Spanish bank account without realising it triggers FBAR. Many buyers open an account before completion to fund the arras (reservation deposit) and immediately exceed the $10,000 threshold — sometimes before they even own the property.
  • Failing to report a Spanish SL. Buyers who structure their purchase through a Spanish company (for inheritance or liability reasons) often don’t realise the company itself creates reporting obligations.
  • Not updating filings after purchase. A buyer who correctly filed FBAR in year one but forgot in year two — perhaps because the account balance dropped and they assumed the obligation had gone — can accumulate penalties across multiple years.
  • Relying on a US accountant who is unfamiliar with Spanish structures. A US CPA who doesn’t know what a nota simple or a comunidad de propietarios account looks like may miss relevant information at filing time.

Coming back into compliance

If you have missed FBAR or FATCA filings, there are IRS-approved programmes designed to allow taxpayers to come back into compliance without the full penalty regime:

  • Streamlined Foreign Offshore Procedures (SFOP) — for US taxpayers residing outside the US. Allows filing 3 years of amended returns and 6 years of FBARs with a 5% miscellaneous offshore penalty (applied to the highest aggregate balance).
  • Streamlined Domestic Offshore Procedures (SDOP) — for US taxpayers residing in the US. Similar structure but with a higher 5% penalty on all unreported assets.
  • Delinquent FBAR Submission Procedures — for taxpayers who have unreported foreign accounts but have no unreported income. Allows filing without a penalty in certain circumstances.

Important: Voluntary disclosure programmes are available only to taxpayers who come forward before the IRS contacts them. Once the IRS has begun an audit or investigation, the streamlined procedures are no longer available. If you believe you have missed filings, seek specialist advice before the IRS finds you first.

Practical Steps Before You Buy

FATCA and FBAR compliance is far easier to get right from the start than to fix retrospectively. Before completing a Spanish property purchase, we recommend American buyers take the following steps:

  1. Engage a US expat tax specialist. Not all CPAs are familiar with the intersection of Spanish and US tax law. Look for a professional with experience in FATCA compliance for property owners specifically — not just generic expat tax filers.
  2. Decide on your ownership structure before exchange. Whether you buy in your personal name, jointly with a spouse, or through a Spanish entity will affect both your US reporting obligations and your Spanish inheritance exposure. This decision is much harder to change after completion.
  3. Keep meticulous records of Spanish accounts. Record the opening and closing balance of each Spanish account each month. This makes threshold calculations straightforward at year-end.
  4. Calendar your filings. FBAR is due 15 April (auto-extended to 15 October). Form 8938 follows your 1040 deadline (15 April for residents, 15 June for overseas filers, extendable to 15 October). Missing either deadline starts the clock on penalties.
  5. Review your obligations annually. Your FBAR and FATCA obligations can change year to year as account balances fluctuate, as you rent out the property, or as your residency status changes. An annual review with your US tax adviser is essential.
