FBAR and FATCA for Americans Abroad: 2026 Guide

If you’re a US person with foreign financial accounts, two federal reporting requirements affect you: FBAR (Foreign Bank Account Report) and FATCA (Foreign Account Tax Compliance Act). Get them wrong and you face penalties that can dwarf the underlying accounts. Get them right and there’s almost no tax cost — these are reporting requirements, not tax requirements.

This article explains what each one is, when you need to file, and the most common mistakes.

TL;DR

• FBAR (FinCEN Form 114): Required if your aggregate foreign account balances exceeded $10,000 at any point during the year. Filed electronically, separate from your tax return.
• FATCA (Form 8938): Required if your foreign account balances exceeded much higher thresholds (varies by filing status and residency). Filed with your tax return.
• Both: Required for most American expats. You file both, not just one.
• Penalties: FBAR penalty can be up to $10,000 per violation per year for non-willful. Willful failures can be $100K+ or 50% of account value. Take this seriously.

What FBAR is

FBAR — formally FinCEN Form 114 — is a report you file with the US Treasury Department (not the IRS) disclosing your foreign financial accounts. It’s not a tax filing. It’s a transparency mechanism. The US government wants to know what foreign accounts US persons have.

Who must file FBAR

You must file FBAR if all of these apply:

1. You are a US person (US citizen, green card holder, resident alien)
2. You have a financial interest in or signature authority over a foreign financial account
3. The aggregate maximum value of all foreign accounts exceeded $10,000 at any time during the calendar year

“Aggregate” means total — if you have a Wise account that peaked at $6K and a UK savings account that peaked at $5K, that’s $11K aggregate → you must file.

What counts as a “foreign account”

Broadly:
– Foreign bank accounts (checking, savings, term deposits)
– Foreign brokerage accounts (Interactive Brokers in Ireland, Saxo, Swissquote)
– Wise (TransferWise) account holdings
– Revolut accounts (if your account is registered to a non-US Revolut entity)
– Foreign mutual fund accounts
– Foreign insurance products with cash surrender value
– Foreign pension accounts (sometimes — depends on type)

Doesn’t count:
– Real estate held directly (not in a fund)
– Foreign stock held in a US brokerage
– Cryptocurrency in non-custodial wallets (but custodial exchange accounts may count)

How to file FBAR

File online at the BSA E-Filing System (bsaefiling.fincen.treas.gov). It’s free. You report each account’s maximum balance during the year, plus the institution name and address.

When to file

Due April 15. Automatic extension to October 15 (no application needed). You don’t need to coordinate with your tax filing.

What you actually report

For each account:
– Bank/institution name and address
– Account number
– Type of account
– Maximum balance during the year (in USD using year-end exchange rates from Treasury’s published list)
– Whether you have a financial interest or just signature authority

That’s it. No tax implications — purely informational.

What FATCA is

FATCA — and specifically Form 8938 for individuals — is the tax-return-attached report of foreign financial assets. It’s filed with your Form 1040.

Who must file Form 8938

The thresholds are higher than FBAR and depend on filing status + residency:

US-resident filers:
– Single / married filing separately: file if foreign assets > $50K at year-end OR > $75K at any point during the year
– Married filing jointly: > $100K year-end OR > $150K at any point

Expat filers (living abroad):
– Single / MFS: > $200K year-end OR > $300K at any point
– MFJ: > $400K year-end OR > $600K at any point

What counts (vs FBAR)

FATCA’s “foreign financial assets” is broader than FBAR’s “foreign financial accounts”:

• All FBAR-reportable accounts
• Plus foreign stocks and securities held directly (not through a US broker)
• Plus foreign partnership interests
• Plus certain foreign insurance/annuity contracts
• Plus certain foreign pension interests

For most expats: if you trigger FATCA, you’ve triggered FBAR. The reverse isn’t always true (FATCA thresholds are higher).

How to file

Attach Form 8938 to your Form 1040. Same calendar as your normal tax filing.

What’s reported

For each foreign asset:
– Description
– Maximum value during year
– Whether it’s an account or other asset
– The institution holding it
– Whether you also filed FBAR for the same asset

There’s overlap with FBAR but they go to different government agencies, so you file both.

The interplay with foreign banks (the bank perspective)

FATCA also imposes requirements on foreign financial institutions (FFIs). Foreign banks must:

1. Identify US-person account holders
2. Report account information annually to the IRS (via their local government)
3. Withhold 30% on US-source payments to non-cooperative US clients

This is why many EU/UK banks won’t open accounts for US persons. The FATCA reporting overhead is expensive, and small banks don’t bother. Big banks (HSBC, Barclays, Deutsche Bank, BNP Paribas) handle it but often with extra paperwork.

For expat banking purposes:
– Interactive Brokers Pro accepts US persons (handles FATCA)
– Wise accepts US persons but may close accounts that show “primarily US-domestic” use patterns
– N26 doesn’t accept US persons (closed all US accounts in 2022)
– Most EU local banks decline US-person applications

Common mistakes

Mistake 1: Thinking FBAR or FATCA threshold means “I owe tax”

No. FBAR and FATCA are reporting only. You owe no tax just for having accounts above thresholds. Tax is owed only on income generated by those accounts (dividends, interest, capital gains), which is reported on your normal Form 1040 / Schedule B.

Mistake 2: Filing FBAR but not Form 8938 (or vice versa)

Different filings, different agencies. If you trigger both thresholds, you file both forms.

Mistake 3: Forgetting Wise or Revolut as foreign accounts

Wise is technically a UK-registered EMI. Revolut accounts are typically registered to a non-US Revolut entity (Lithuanian, EU). Both count for FBAR. The fact that they’re “fintech” not “traditional banks” doesn’t exempt them.

Mistake 4: Reporting only year-end balance

FBAR asks for maximum balance during the year. If your account peaked at $20K in July but ended the year at $5K, you report $20K.

Mistake 5: Not filing because “the bank doesn’t know I’m American”

If a foreign bank discovers you’re a US person, they’ll report you under FATCA regardless. Your tax authority will get the report. The IRS will eventually know. You can’t hide foreign accounts indefinitely. File proactively.

Mistake 6: Procrastinating on prior years

If you should have filed FBAR/FATCA in prior years but didn’t, you may qualify for the Streamlined Filing Compliance Procedures — a forgiveness program for non-willful failures. Penalties are usually waived. Get a cross-border tax preparer to handle this; it’s not a DIY situation.

Mistake 7: Thinking only US-resident tax pros can help

Most US-domestic tax preparers don’t know FBAR/FATCA. Use a cross-border specialist: Greenback Expat Tax, Bright!Tax, MyExpatTaxes, or a CPA experienced with American expats.

Penalties (the part that motivates compliance)

FBAR failure-to-file penalties:
– Non-willful failure: up to $10,000 per violation per year (recently adjusted)
– Willful failure: the greater of $100,000 OR 50% of the account balance, per violation per year
– Criminal penalties for fraud: up to $250K and 5 years prison

FATCA Form 8938 penalties:
– Initial failure: $10,000
– Continued failure after IRS notice: $10,000 every 30 days, up to $50,000 additional
– Reduced statute of limitations for related underpaid tax

Multiple-year failures stack. Someone with 10 years of unreported foreign accounts could face penalties exceeding their account balances multiple times over.

The 2026 reality

The US has dramatically expanded FATCA enforcement since 2014. Almost every country in the world has an Intergovernmental Agreement (IGA) with the US that automates the data flow. Your foreign bank reports to your local tax authority, which reports to the IRS.

Realistic assumption: the IRS will eventually know about every meaningful foreign account you have. The question is whether you reported it yourself proactively (no penalty) or whether they found out from a bank report (penalty).

File proactively. The reporting itself is free. The penalties for not filing are catastrophic.

Practical workflow

1. Track foreign accounts as you open them. Keep a list: institution, account number, currency, opening date.
2. Track maximum balances during the year. Most online banking shows this; if not, save monthly statements.
3. Use a cross-border tax preparer. Don’t DIY FBAR/FATCA. The fee ($500-1500/year for moderate complexity) is worth it.
4. File on time, every year. The system is designed to assume non-filers are non-willful — until you’ve been caught and noticed, then willfulness becomes harder to argue.
