FBAR: The $10,000 Rule Every US Expat Must Know

The $10,000 FBAR threshold is not per account. It is the combined total across every foreign financial account you hold, and it applies the moment your balances hit that number on any single day of the year — not just December 31. A $6,000 checking account in Portugal and a $5,000 savings account in Mexico means you crossed the threshold in July and owe a federal filing even if both accounts are nearly empty by December.

The Report of Foreign Bank and Financial Accounts, officially FinCEN Form 114, has been required for Americans with foreign accounts since 1970. Enforcement has sharpened significantly over the past decade, and the penalties for missing it start at $10,000 per year for non-willful violations, before reaching criminal territory. Yet most expats who should file it have never heard of it.

What Is the FBAR?

FBAR stands for Report of Foreign Bank and Financial Accounts. It is filed using FinCEN Form 114, and it goes to the US Treasury's Financial Crimes Enforcement Network — not to the IRS. You do not attach it to your tax return. It is filed separately through the BSA E-Filing System, and it is free to submit.

The FBAR is a disclosure requirement, not a tax. You do not pay tax on the accounts you report; you simply tell the government they exist. But failing to disclose when you are required to carries penalties that can dwarf the tax liability from the accounts themselves.

The obligation traces back to the Bank Secrecy Act of 1970. For decades, enforcement was sporadic. That changed after the 2008 UBS whistleblower case and subsequent FATCA legislation, when the US government began receiving systematic account data from foreign financial institutions in dozens of countries. The IRS now cross-references that data against FBAR filings. Accounts that show up in foreign bank reports without a matching FBAR trigger audits.

The $10,000 Aggregate Rule, Explained

You must file an FBAR if the aggregate maximum value of all your foreign financial accounts exceeded $10,000 at any time during the calendar year. Three elements of that sentence are easy to misread:

1. Aggregate — the $10,000 is not per account. It is the sum of all reportable foreign accounts you hold worldwide. Two accounts, each below $10,000, still trigger a filing obligation if their combined high-water marks exceed the threshold in any single day.
2. Maximum value — you use the highest balance in each account during the year, converted to US dollars at the official Treasury exchange rate for the last business day of that calendar year. The year-end balance does not matter if a higher balance appeared in March.
3. At any time — the threshold is not based on a year-end snapshot. A $25,000 wire transfer that sits in a foreign account for two days in August and is then repatriated still counts. The account crossed $10,000. The FBAR is required.

What Accounts and Assets Must Be Reported

The FBAR covers foreign financial accounts, which includes a wider range of accounts than most people expect.

Account Type	FBAR Required?	Notes
Foreign checking or savings account	Yes	Most common reportable account
Foreign brokerage or investment account	Yes	Includes foreign stock accounts and managed funds
Foreign mutual fund	Yes	Foreign funds are reportable even if bought through a US platform
Foreign pension (Australian Super, Canadian RRSP, UK workplace pension)	Generally yes	Most foreign pension accounts with a determinable cash value are reportable
Foreign life insurance with cash value	Yes	Term policies without cash surrender value are excluded
Joint account	Yes	Counted in full even if you own only a portion of the funds
Cryptocurrency held at a foreign exchange	Not currently required	FinCEN proposed rules but has not finalized them as of tax year 2025; watch for updates
US-based foreign account at a domestic bank	No	An account at a US bank's domestic branch is not a foreign account

Note on joint accounts: both spouses with ownership interest in a joint account must typically file, or one spouse may file the joint FBAR and the other must indicate consent. A joint account is counted at its full value for each co-owner, not split proportionally.

For expats managing a banking stack across multiple countries, see our zero-fee expat banking guide for how to structure accounts efficiently — while staying compliant on the reporting side. Charles Schwab is also worth considering as a US anchor account, since it reimburses ATM fees worldwide and keeps your domestic account clearly separate from foreign holdings.

Signature Authority: The Rule That Catches Employees

You do not need to own a foreign account for the FBAR obligation to apply. If you have signature or other authority over a foreign account — meaning you can direct transactions, sign on the account, or otherwise control the disposition of its assets — that account must appear on your FBAR if the aggregate crosses $10,000.

This rule catches a specific and often surprised group: employees of multinational companies who have signing authority over an employer's foreign operating accounts. A US-citizen finance manager in Singapore who can authorize wire transfers from the Singapore entity's local bank account has signature authority over a foreign account. If that account ever holds more than $10,000, it belongs on her personal FBAR — even though she owns none of the money.

FBAR vs. Form 8938: Two Different Reports

Both FBAR and Form 8938 report foreign financial information to the US government. They are not the same form, they go to different agencies, and meeting one threshold does not exempt you from the other.

Feature	FBAR (FinCEN 114)	Form 8938 (FATCA)
Filed with	FinCEN (BSA E-Filing System)	IRS (attached to Form 1040)
Threshold — expats living abroad (single)	$10,000 aggregate at any time	$200,000 on Dec 31 or $300,000 at any point
Threshold — expats living abroad (MFJ)	$10,000 aggregate at any time	$400,000 on Dec 31 or $600,000 at any point
Threshold — US residents (single)	$10,000 aggregate at any time	$50,000 on Dec 31 or $75,000 at any point
What it covers	Foreign financial accounts only	Foreign accounts AND other foreign assets (stocks, partnerships, foreign business interests)
Penalty for non-filing	Up to $16,536 per year (non-willful)	$10,000 to $50,000

The most important difference: Form 8938 covers a broader universe of assets than the FBAR. Foreign stock held directly (not in an account) or ownership in a foreign partnership would appear on Form 8938 but might not appear on FBAR if it is not held in a financial account. See the IRS comparison table for a side-by-side breakdown by asset type.

Many expats above the $10,000 FBAR threshold are below the $200,000–$300,000 Form 8938 threshold and only need to file the FBAR. But those with significant foreign investment portfolios often owe both.

Penalties for Missing the FBAR

FBAR penalties are among the most severe in the US tax code relative to the underlying tax obligation. They are assessed per year, not per account (a taxpayer-favorable rule clarified by the Supreme Court in Bittner v. United States in 2023).

Non-Willful Violations

If you failed to file an FBAR because you did not know the requirement existed, or because of an honest mistake, the IRS may assess a non-willful penalty of up to $16,536 per year (2025 inflation-adjusted amount). Following the Bittner decision, this is assessed per form, not per account — meaning one year of non-filing that covered five accounts is still one penalty, not five.

In practice, the IRS has discretion to waive or reduce non-willful penalties when the taxpayer proactively discloses through the appropriate program before being contacted by the IRS. The Streamlined Foreign Offshore Procedure (for expats) and the Delinquent FBAR Submission Procedures are the two main catch-up paths.

Willful Violations

If the IRS determines you knowingly failed to file, or made a conscious effort to avoid learning about your filing obligations (the legal standard of "willful blindness"), the penalty is the greater of $165,353 or 50% of the account balance at the time of the violation. For multi-year non-compliance, penalties can exceed the value of the accounts themselves.

Willful violations can also carry criminal penalties: fines up to $250,000 and up to 5 years imprisonment, rising to $500,000 and 10 years if combined with other violations.

How to File the FBAR

The FBAR is filed electronically through the BSA E-Filing System maintained by FinCEN. There is no paper alternative for most individual filers. The steps:

1. Gather the account details for every foreign financial account you held during the year: account number, bank name, country, and the maximum value during the year (converted to USD using the Treasury's annual exchange rate).
2. Access the BSA E-Filing portal. You can file without registering using the "No Registration" path for individual filers.
3. Complete FinCEN Form 114. For joint accounts, both spouses may be required to file separately, or one may file on behalf of both using the joint filing option.
4. Submit by April 15. If you miss the deadline, an automatic extension to October 15 applies — you do not need to request it. No payment accompanies the FBAR; it is a disclosure only.
5. Keep records. Retain copies of the FBAR and supporting account documentation for 5 years after the due date of the report.

For expats also filing US income taxes from abroad, the FBAR due date aligns with the tax return calendar. See our guide on the FEIE vs. Foreign Tax Credit for how to handle income tax obligations while living overseas — that's separate from the FBAR but both are typically due together.

Missing FBARs: How to Catch Up Without Penalty

The IRS offers two specific programs for filers who missed FBARs due to non-willful oversight:

Streamlined Foreign Offshore Procedure

For US persons living outside the United States who have not filed FBARs (or income tax returns) for non-willful reasons, the Streamlined Foreign Offshore Procedure allows you to file 3 years of amended or delinquent tax returns plus 6 years of FBARs, pay any outstanding tax and a 5% penalty on the highest aggregate balance of unreported accounts, and receive full penalty abatement on the FBAR non-filing penalty.

Eligibility requires certification that the non-compliance was not willful and that you meet the foreign residency requirement (roughly, you were outside the US for at least one of the three years you are filing).

Delinquent FBAR Submission Procedures

If you have not filed FBARs but have otherwise reported all income on your tax returns correctly, you may be able to submit the missing FBARs with an explanation and receive penalty relief without formal disclosure. This path is available only when the IRS has not already contacted you about the delinquency.

Do not attempt either program without first consulting an international tax attorney or a CPA who specializes in FBAR compliance. Using the wrong program, or qualifying incorrectly, can expose you to the full penalty regime rather than eliminating it.

Five FBAR Mistakes Expats Make Repeatedly

1. Treating the threshold as per account, not aggregate. As noted above, the $10,000 applies to the combined total — not each account individually.
2. Using the December 31 balance instead of the year's high-water mark. You must report the maximum value reached at any point during the year, not just the year-end balance.
3. Ignoring foreign pension accounts. Australian Superannuation, Canadian RRSPs, UK employer pensions, and similar accounts are generally reportable. The fact that you cannot access the money does not remove the filing obligation.
4. Overlooking accounts with signature authority. Employees with access to employer overseas accounts often don't realize the FBAR obligation follows the authority, not the ownership.
5. Confusing FBAR with Form 8938 and assuming one covers the other. They are separate filings to separate agencies. Meeting the FBAR threshold and filing FinCEN 114 does not satisfy any Form 8938 obligation.

Conclusion

The FBAR is a straightforward annual disclosure — a single electronic form filed free through the BSA portal — but the rules around what triggers it, what must be reported, and how far penalties can reach are anything but simple. The $10,000 aggregate threshold catches far more expats than the headline number suggests, and the consequences of missing a filing are disproportionate to how much work the form itself takes.

If you have foreign accounts and have never heard of FinCEN Form 114, file a current-year FBAR by October 15 and look into the Streamlined Foreign Offshore Procedure for prior years before the IRS cross-references its international banking data against your returns.
