If you’re a US citizen or green card holder living abroad, you already know about filing US taxes. What catches many expats off guard is the separaterequirement to report foreign bank accounts — and the catastrophic penalties for getting it wrong. An expat who never owed a dollar in US tax has been fined $100,000+ for failing to file a form they didn’t know existed.
This guide covers FBAR, FATCA, and the practical banking strategies that every US expat needs for 2026.
FBAR vs FATCA: What’s the Difference?
| Metric | 🇺🇸 FBAR (FinCEN 114) | 🇺🇸 FATCA (Form 8938) |
|---|---|---|
| Who Files? | US persons with $10K+ in foreign accounts | US taxpayers with foreign assets above thresholds |
| Threshold (Abroad, Single) | $10,000 aggregate max value | $200,000 year-end / $300,000 at any point |
| Threshold (Abroad, MFJ) | $10,000 aggregate max value | $400,000 year-end / $600,000 at any point |
| What's Covered? | Bank accounts, investment accounts, pensions | Bank accounts PLUS stocks, mutual funds, foreign insurance, partnership interests |
| Filed Where? | FinCEN (Treasury) — online only | IRS — attached to tax return |
| Deadline | April 15 (auto extension to Oct 15) | With tax return (June 15 for expats) |
| Non-Willful Penalty | Up to $12,921/violation | $10,000/unreported asset |
| Willful Penalty | $165,353 or 50% of account balance | $50,000+ per violation |
Critical point: These are SEPARATE requirements. If you have $250,000 in a foreign bank account, you must file BOTH the FBAR and Form 8938. They go to different agencies (Treasury vs IRS) with different forms and deadlines.
FBAR: The Filing Everyone Forgets
Who Must File?
Any “United States person” — citizen, green card holder, or US resident — who has a financial interest in, or signature authority over, foreign financial accounts if the aggregate maximum value of ALL accounts exceeded $10,000 at any point during the year.
This means: if you have €5,000 in a Spanish bank account and €6,000 in a Portuguese investment account, you must file even though neither individually exceeds $10,000.
What Accounts Are Reported?
- Bank accounts (checking, savings) — even joint accounts where you’re not the primary holder
- Brokerage and investment accounts
- Mutual funds held at foreign institutions
- Foreign pension accounts (including employer pensions)
- Cash-value foreign life insurance policies
- Accounts you have signature authority over (even if not your money — e.g., company accounts)
How to File
- Go to the BSA E-Filing System (bsaefiling.fincen.treas.gov)
- Complete FinCEN Form 114 electronically
- Report each account: institution name, account number, maximum value during the year, country
- Convert all amounts to USD using the Treasury’s year-end exchange rate
- Deadline: April 15, with automatic extension to October 15 (no form required for extension)
2026 Penalty Structure
- Non-willful violation: Up to $12,921 per account per year (adjusted annually for inflation)
- Willful violation: The greater of $165,353 or 50% of the account balance at time of violation
- Criminal penalties: Up to $500,000 fine and/or 10 years imprisonment for willful violations
- Reasonable cause defense: Available for non-willful violations if you can demonstrate the failure was due to reasonable cause, not willful neglect
FATCA: The Bank’s Side of the Equation
FATCA works in two directions:
- You → IRS: Form 8938 reporting your foreign assets (filed with your tax return)
- Foreign banks → IRS: Over 110 countries automatically transmit US account holder data to the IRS. Your bank reports your balance whether you file or not.
The Banking Problem
FATCA compliance costs money for foreign banks. Many institutions have decided it’s easier to simply refuse US clients than to maintain compliance infrastructure. This affects expats in every country.
FATCA-Friendly Banks by Country
- Portugal: Caixa Geral de Depósitos (state-owned, 543 branches), Millennium BCP, ActivoBank (digital)
- Spain: BBVA, Santander, CaixaBank — all large enough for FATCA compliance
- Mexico: BBVA Bancomer, Banorte (no minimum balance), Santander México
- Germany: Deutsche Bank, Commerzbank, N26 (neo-bank, US-friendly)
- Netherlands: ING, ABN AMRO, Bunq (expat-friendly digital bank)
- Thailand: Bangkok Bank, Kasikornbank — both accept US clients with proper documentation
- Japan: SMBC, MUFG — possible but bureaucratic
- UK: HSBC, Barclays — generally accept US clients
Tip: Open your foreign bank account as early as possible after arrival. Bring your passport, local residence proof, NIE/BSN/tax number, and a letter from your employer. Many banks require an in-person appointment. See our full expat banking guide →
Compliance Timeline for New Expats
- Before leaving the US: Establish domicile in a no-income-tax state (Texas, Florida, Nevada, Wyoming) if you haven’t already. This avoids ongoing state tax filing.
- Month 1 abroad: Open a foreign bank account. Start tracking your foreign account balances.
- April 15: FBAR due (auto-extended to Oct 15). US tax return due (auto-extended to June 15 for expats abroad).
- June 15: Extended US tax return deadline for expats. File Form 2555 (FEIE) and Form 8938 (FATCA) with your return.
- October 15: Final FBAR deadline. Final US tax return deadline (with extension filed).
If You Haven’t Been Filing
The IRS offers two amnesty programs for late filers:
- Streamlined Filing Compliance Procedures: For non-willful failures. File 3 years of tax returns + 6 years of FBARs. Penalty: 5% of highest aggregate foreign account balance (foreign residents) or $10,000 per year (US residents). This is by far the most common path.
- Delinquent FBAR Submission Procedures: For those who only missed FBAR filings (not tax returns). File late FBARs with a reasonable cause statement. Generally no penalty if you owed no tax.
Do not ignore this. The IRS receives your account data automatically from 110+ countries. Voluntary disclosure always results in better outcomes than getting caught.

Frequently Asked Questions
I've lived abroad for years and never filed FBAR. Am I in trouble?▾
Potentially, but there are amnesty programs. The Streamlined Filing Compliance Procedures are designed specifically for non-willful late filers. You'll need to file 3 years of back tax returns and 6 years of FBARs. If you're living abroad and the failure was non-willful, penalties are often limited to 5% of the highest aggregate balance. Consult an expat tax specialist — do not attempt to 'quietly' file without using the proper amnesty program.
Do I need to report my foreign retirement/pension account?▾
On the FBAR: yes, if it's a financial account (most pensions qualify). On Form 8938: yes, if it meets the threshold. On your tax return: it depends on the type of account and the tax treaty. Some foreign pensions are tax-deferred under treaty provisions; others are taxable annually on accrued gains. UK SIPPs, Australian super, and Canadian RRSPs each have specific treaty treatments. This is one area where an expat tax specialist is highly recommended.
What if my foreign bank refuses to open an account because I'm American?▾
This is increasingly common. Strategies: (1) Try larger national banks which are more likely to have FATCA compliance infrastructure, (2) Use digital banks like Wise, Revolut, or N26 which are US-friendly, (3) Ask your employer for a referral to their corporate bank, (4) In the EU, invoke the Payment Account Directive which gives EU residents the right to a basic bank account regardless of nationality. Keep your US bank account open as a backup.
Do cryptocurrency accounts count for FBAR/FATCA?▾
As of 2026, the IRS position is evolving. Foreign crypto exchanges ARE reportable on FBAR if they qualify as 'foreign financial accounts.' The IRS added a crypto question to Form 1040 and is increasing enforcement. Decentralized wallets (MetaMask, Ledger) are generally NOT reportable since they're not held at a 'financial institution.' However, report all crypto gains/losses on your tax return regardless.
Can I reduce my FBAR obligation by keeping money in the US?▾
Yes, strategically. Many expats maintain a US bank account for receiving income and keep foreign accounts below $10,000 to avoid FBAR filing. However, this only avoids FBAR — if you have other foreign financial assets exceeding the FATCA thresholds, Form 8938 still applies. And keeping large sums in the US while living abroad creates currency exchange inefficiency. Most expats find it simpler to file the FBAR than to artificially manage account balances.
