Mortgage in Spain for US citizens
FATCA-aware guide · Updated Jul 2026
US citizens face two complications when buying in Spain: FATCA reporting (some banks refuse American clients) and IRS double-filing (Form 8938, FBAR). LTV typically 60-65% with USD income buffer of 10-20%. This guide covers exactly what American buyers need.

FATCA: what every American buyer must know
The Foreign Account Tax Compliance Act (FATCA) is US legislation requiring foreign banks worldwide to report accounts held by US persons (citizens, green card holders, certain residents) to the IRS. Spanish banks signed an Inter-Governmental Agreement (IGA Model 1) with the US in 2013 — they report your Spanish account data to the Spanish Tax Agency, which forwards to the IRS.
What this means for you:
- When you open a Spanish bank account, you must complete IRS Form W-9 (Request for Taxpayer ID) confirming you are a US person
- Your Spanish bank automatically reports balance and interest to the IRS each year
- Some smaller Spanish banks refuse to open accounts for US persons due to compliance burden — stick to major banks (CaixaBank, Bankinter, Santander, BBVA)
- Failure to declare your account on US tax return triggers IRS penalties — even though Spain already reports it
FATCA-friendly banks confirmed (2026): CaixaBank (HolaBank), Bankinter International, Santander Spain, BBVA, Sabadell Solbank, Deutsche Bank Spain. Avoid: regional cooperatives (Caja Rural variants) that may have FATCA refusal policy.

Owning Spanish property as a US person triggers multiple US reporting obligations beyond the Spanish ones:
📄 FBAR (FinCEN 114)
Report all foreign accounts if combined balance exceeds $10,000 at any point during the year. Filed online by April 15 (auto-extension to October 15). Penalty for non-filing: $10,000+ per account per year. Includes Spanish current accounts but NOT mortgage debt (debt is not an "asset").
📋 Form 8938
Statement of Specified Foreign Financial Assets. Filed with your Form 1040. Threshold: $50,000 single year-end ($100k any time during year), $200,000 married filing jointly ($400k any time). Penalties up to $50,000 + 40% under-statement of tax.
🏛️ Spain-USA Treaty
Treaty (1990, protocol 2013) prevents double taxation. Real estate income taxable where property is (Spain). Pension income mostly taxable by US. Capital gains on Spanish property: Spain first, US gives credit for Spanish tax paid.
⚠️ PFIC trap
If you become Spanish tax resident and hold Spanish/EU mutual funds (UCITS) or ETFs, the IRS may classify them as Passive Foreign Investment Companies (PFIC) with punishing tax treatment. Avoid until you understand the rules. US-domiciled ETFs are generally safe.
Recommendation: consult both a Spanish gestor (for ITP/IRNR) and a US CPA familiar with FATCA/FBAR/8938 before signing. Mistakes here are expensive.

Common pitfalls for American buyers
⚠️ Forgetting FBAR
Most common American mistake. Once your Spanish account hits $10k (instant after deposit), you have an FBAR obligation by April 15. Penalty $10k+ per account.
⚠️ Approaching FATCA-refusing banks
Don't waste 4-6 weeks with smaller cooperatives that decline US persons. Stick to CaixaBank, Bankinter, Santander, BBVA from the start.
⚠️ Not declaring on Form 8938
Filed with your 1040 — easy to forget if your CPA is not familiar with Spanish accounts. $10k-$50k penalty + 40% under-statement.
⚠️ Buying via LLC
Common in US but problematic in Spain — creates Spanish corporate tax obligations, higher ITP and complications. Buy in your name unless you have a strong reason otherwise.
⚠️ PFIC trap with Spanish funds
Once you're Spanish tax resident, holding Spanish UCITS/ETFs creates IRS PFIC issues. Use US-domiciled ETFs instead.
⚠️ Underestimating timeline
Apostille via State Department: 4-8 weeks. NIE via consulate: 4-6 weeks. Most American applicants underestimate this and lose property to faster buyers.
