FBAR Explained: Which Expats Must File FinCEN 114

The FBAR trigger is not your year-end balance. It is the highest point your foreign accounts reached at any single moment during the calendar year — and it is aggregate across every account you hold outside the US. If five foreign accounts each peaked at $3,000 on different days, you still crossed $10,000 and were required to file. That arithmetic surprises more Americans abroad than almost any other reporting rule, and the penalties for missing it are severe enough to permanently alter the math of living overseas.

This guide covers exactly who must file FinCEN Form 114, which accounts count, how FBAR differs from FATCA's Form 8938, and what relief exists for people who have missed filings in prior years. For the broader picture of banking and tax setup abroad, start with the US expat banking and taxes guide.

What Is the FBAR?

FBAR stands for Report of Foreign Bank and Financial Accounts. The form itself is FinCEN Form 114, filed electronically through the Financial Crimes Enforcement Network's BSA E-Filing System — not through the IRS, and not attached to your tax return. It is a Bank Secrecy Act compliance document, not a tax return, which is why many expats miss it: their tax software may not prompt for it, and it is filed on a separate platform entirely.

The law authorizing FBAR sits in Title 31 of the US Code (not Title 26, where the tax code lives). FinCEN, not the IRS, owns and enforces the requirement — though the IRS assists with civil penalty assessment in many cases. This dual-agency structure matters because FBAR penalties are separate from tax penalties and are assessed even in years where you owe zero income tax.

Who Must File

Any US person with 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 must file an FBAR. "US person" under the Bank Secrecy Act includes:

• US citizens — regardless of where they live
• Resident aliens (green card holders) — regardless of whether they were physically present in the US that year
• US domestic entities: corporations, LLCs, partnerships, trusts, and estates organized in the US

Physical presence in the US is irrelevant. A US citizen who has lived in Lisbon for ten years, holds a Portuguese bank account, and has never exceeded the income threshold for owing US income tax is still required to file an FBAR if that account ever had more than $10,000 in it during the year.

Signature Authority: The Business Owner Trap

The signature authority rule catches business owners and senior employees who do not personally own foreign accounts but control them. A US-citizen CFO who has signing authority over a company's foreign bank account — even if the account belongs entirely to a foreign entity — may need to file an FBAR for that account. Treasury regulations provide some carve-outs for publicly traded entities and certain other entities, but the default rule is broad.

What Accounts Are Reportable

The $10,000 threshold applies to aggregate highest value across all foreign financial accounts. If you have three accounts, you add the peak values from each to see if you crossed the threshold. Once you do, every account must be reported — even one with a $200 balance.

Account Type	FBAR Reportable?	Notes
Foreign bank account (savings, checking)	Yes	Report maximum value during the year, not year-end balance
Foreign brokerage / securities account	Yes	Includes accounts holding foreign stocks, bonds, ETFs
Foreign mutual fund account	Yes	Even if directly registered rather than held in a brokerage
Foreign pension (held outside formal plan)	Yes	Many expat private pension accounts qualify; formal employer plans may be exempt
Foreign life insurance with cash surrender value	Yes	Term life with no CSV is not reportable
Cryptocurrency held on foreign exchanges	Currently No	FinCEN has proposed expanding rules; rule not yet finalized as of June 2026
Foreign PayPal or Revolut balance	Unclear	FinCEN has not issued definitive guidance; conservative practitioners report these
US branch of a foreign bank (US account)	No	Account must be held at a foreign branch to be reportable
Foreign branch account of a US bank	Yes	The physical location of the branch, not the bank's nationality, determines status

How the $10,000 Aggregate Actually Works

Because the threshold triggers on aggregate, an expat with only modest savings spread across a few foreign accounts for convenience can cross $10,000 without realizing it. Opening a new account, receiving a payment from a client, or simply keeping an emergency fund in a local bank is enough to trigger the requirement.

FBAR vs. FATCA Form 8938: Which One Do You File?

Both forms report foreign financial information, and both can apply in the same year to the same person — but they are not interchangeable, and filing one does not satisfy the other.

	FBAR (FinCEN 114)	Form 8938 (FATCA)
Filed with	FinCEN directly (BSA E-Filing System)	IRS — attached to your annual tax return
Filing threshold (expats living abroad)	$10,000 aggregate at any point	$200,000 (single) / $400,000 (joint) year-end, or $300,000 / $600,000 at any time
What it covers	Foreign financial accounts only	Foreign financial accounts AND other foreign financial assets (stocks, partnerships, interests not held in accounts)
Governing law	Bank Secrecy Act (Title 31)	Internal Revenue Code (Title 26 / FATCA)
Due date	April 15; automatic extension to October 15	Same as income tax return, including extensions
Non-willful penalty	Up to $16,536 per year	$10,000 initially, up to $60,000 for continued failure
Crypto-only accounts	Currently not reportable	Currently not required (also pending further guidance)

Most expats with a Charles Schwab international brokerage account or another US-flagged account held domestically do not need to report that account on FBAR — it is a US account regardless of where they physically are. FBAR is about accounts at foreign financial institutions. For a practical account setup that keeps most reporting simple, the expat banking guide covers which US accounts survive the move abroad.

FBAR Penalties: What the IRS Can Actually Assess

FBAR penalties have a long history of aggressive enforcement and landmark court cases. The current framework, shaped by the 2023 Supreme Court decision in Bittner v. United States, applies penalties per annual report for non-willful violations — not per account.

Non-Willful Violations

A non-willful violation is one where the filer did not know about the FBAR requirement or made a mistake without intent to conceal. As of 2026, the inflation-adjusted non-willful cap is $16,536 per calendar year (per late or incorrect report). Before Bittner, the IRS often assessed this per account, per year — turning five unreported accounts into a $50,000+ annual penalty. The Supreme Court's ruling limited this to per-year (per form).

The "per-year" structure still allows significant penalties for multi-year failures. A non-filer who missed seven years of FBAR on one account faces a potential $115,752 in non-willful penalties — before any reduction for reasonable cause.

Willful Violations

Willfulness means you knew about the FBAR requirement and chose not to comply — or were reckless about finding out. The IRS treats checking "no" on Schedule B (which asks about foreign accounts) while having unreported foreign accounts as strong evidence of willfulness. For willful violations, penalties remain per account, per year:

• Greater of $165,353 (2026 inflation-adjusted figure) or 50% of the highest account balance during the violation year
• Penalties can be stacked across years — a single account unreported for five years can trigger multiple willful penalties
• Criminal penalties: up to $500,000 in fines and up to 10 years imprisonment

Cryptocurrency and FBAR

As of June 2026, FinCEN has not finalized rules requiring foreign cryptocurrency exchange accounts to be reported on FBAR. The current stance is that virtual currency held on foreign exchanges is not reportable under the existing rule — which only covers "currency or monetary instruments" held in traditional financial accounts.

FinCEN published a notice in December 2020 signaling intent to expand FBAR coverage to include foreign accounts holding virtual currency, but the proposed rulemaking process has not produced a final rule. Conservative tax practitioners recommend reporting foreign crypto exchange accounts as a precaution, because once a final rule is published the obligation will apply to newly covered accounts in that year — not retroactively.

If you hold cryptocurrency on a foreign exchange that also holds fiat currency in the same account, that account may already be reportable under current rules based on the fiat portion.

How to File the FBAR

FBAR is filed electronically through the BSA E-Filing System at bsaefiling.fincen.treas.gov. The system requires a free account registration and allows individual filers to submit FinCEN Form 114 directly without a paid preparer. Expats who prefer a tax professional can authorize one to file on their behalf.

Information required to complete the form:

• Your name, address, and Social Security Number or ITIN
• Name and address of each foreign financial institution
• Account number for each reported account
• Maximum value of each account at any point during the reporting year (convert to USD using the Treasury's official year-end rate)
• Account type (bank deposit, securities, other)

Use the US Treasury's published Financial Management Service exchange rates (not a spot rate or an average) for foreign currency conversion. The Treasury publishes year-end rates in December each year; this is the conversion basis regardless of when the peak value actually occurred.

Data note: penalty figures and exchange rate rules verified June 2026. Non-willful penalty amounts are inflation-adjusted annually by FinCEN. The Bittner v. United States ruling (2023) governs non-willful per-form penalty structure; the IRS has not appealed or legislatively overturned this.

Late Filing Relief: You Have Options

Missing an FBAR is common among expats who discover the requirement years after their first foreign account opened. Several structured relief paths exist before you face a formal penalty assessment.

Delinquent FBAR Submission Procedures

If you have not been contacted by the IRS or FinCEN about the failure, you can file your late FBARs directly through the BSA E-Filing System with a statement of reasonable cause attached. If the IRS agrees the failure was non-willful and resulted from reasonable cause (not a pattern of deliberate concealment), penalties may be waived entirely. This is the lowest-friction path for first-time late filers.

Streamlined Foreign Offshore Procedures

If you also have unfiled US tax returns (a common combination — expats who did not know they had to file), the Streamlined Foreign Offshore Procedures allow you to catch up on three years of tax returns and six years of FBARs simultaneously. There is a 5% penalty on the highest aggregate unreported foreign account balance — significantly less than the standard non-willful cap. Eligibility requires that you lived outside the US and that the failure was non-willful.

Voluntary Disclosure Program

If your failure was willful — you knew about FBAR and chose not to file — the IRS Criminal Investigation Voluntary Disclosure Program (CI-VDP) is the appropriate path. It does not guarantee immunity from prosecution, but good-faith participation and full disclosure typically result in civil penalties rather than criminal charges. Willful non-filers who do nothing and are later discovered face the full penalty regime plus potential criminal exposure.

FBAR Pre-Filing Checklist

1. List every bank, brokerage, pension, and financial account you held at any point outside the US during the year
2. Obtain account statements showing the highest balance in each account during the year
3. Convert peak values to USD using Treasury FMS year-end exchange rates
4. Add the converted peak values across all accounts to determine aggregate
5. If aggregate exceeds $10,000 at any point, every account must be reported regardless of individual balance
6. Check whether you have signature authority over any additional foreign accounts (business, joint, trust)
7. Verify Part III of Schedule B on your income tax return answers "yes" if any foreign accounts exist
8. File FinCEN Form 114 by April 15 (or October 15 if extending) — separate from your tax return
9. Determine whether Form 8938 (FATCA) is also required based on total foreign asset values
10. If late, file through the appropriate relief program before the IRS contacts you

FBAR in the Context of Your Overall Expat Strategy

FBAR compliance is a floor, not a ceiling. Once you have it handled, the next questions are about tax efficiency: which accounts to keep, which to close, and how to structure income across jurisdictions. If you hold foreign mutual funds or offshore investment wrappers, the expat investing and PFIC guide covers the separate — and more punishing — tax rules that apply to those assets for US persons.

Expats who use US-based accounts abroad — particularly Charles Schwab for brokerage and fee-free international ATM withdrawals — keep FBAR exposure minimal because US-domiciled accounts are not reportable regardless of where you withdraw from them. If you also run a US business from abroad, Mercury Bank is a commonly used choice for US business banking that does not require physical presence to open or maintain. Neither account creates FBAR reporting obligations.

Conclusion

The FBAR's $10,000 aggregate threshold is low enough to catch almost any expat with a local bank account abroad. The surprise is not the form itself — it is that the threshold is measured at the highest point during the year, across all accounts, not at year-end and not per account. If your combined foreign accounts ever touched $10,000, you had an obligation to file.

The good news is that non-willful late filers who proactively use the Delinquent FBAR Submission Procedures or the Streamlined Foreign Offshore Procedures regularly avoid penalties entirely. The bad news is that willful non-filing carries penalties that can exceed account balances. The path forward is simple: file every year, answer Schedule B honestly, and use the relief programs if you discover a gap.
