FBAR and the $10,000 Rule: Misconceptions That Cost Expats

What is the FBAR?

The Report of Foreign Bank and Financial Accounts, commonly known as the FBAR, is a mandatory disclosure for US persons with financial interests abroad. It is an informational report, filed on FinCEN Form 114 with the Financial Crimes Enforcement Network. The FBAR is entirely separate from your federal income tax return.

Does the $10,000 FBAR threshold apply to each account separately?

The most common error expats make is assuming the threshold applies to each account individually. The rule is based on the aggregate value across all your foreign financial accounts. If you have three accounts with $4,000 in each, your aggregate total is $12,000. This means you must report all three accounts on your FBAR. The requirement is triggered once the combined total exceeds $10,000, so a balance that peaks at exactly $10,000 does not trigger it. Our FBAR and Form 8938 threshold checker works out which reporting lines your own accounts and assets cross, including the cases where one form is required and the other is not.

Does the FBAR depend on my balance on December 31?

You cannot avoid reporting by transferring funds before December 31. The FBAR requirement is triggered if your aggregate balance exceeds $10,000 at any point in the calendar year. Even if the balance was only above the threshold for a single day, you are required to file.

Two accounts each under $10,000: do I file an FBAR?

Yes, if the two peaks add up to more than $10,000. The threshold is aggregate, not per-account, and the aggregation is not a simultaneous-balance test: you take the highest value each foreign account reached at any point in the year and add those maximums together, so two accounts that peak at $6,000 in different months sum to $12,000 and cross the $10,000 FBAR threshold between them. Two accounts that peak at $4,000 each sum to $8,000 and do not. FinCEN states the computation in one sentence: “If the maximum account value of a single account or aggregate of the maximum account values of multiple accounts exceeds $10,000, an FBAR must be filed.” Neither account has to be near the threshold on its own, and neither has to be open on the same day as the other. Once the total crosses, account size stops mattering: every reportable account goes on the form, including ones that never came close on their own. The obligation itself sits in 31 CFR §1010.350(a), which requires each US person with a financial interest in, or signature or other authority over, a bank, securities, or other financial account in a foreign country to report that relationship for each year it exists; the $10,000 figure is set by 31 CFR §1010.306(c).

Which foreign accounts count toward the FBAR?

The FBAR covers much more than standard checking and savings accounts. You must include foreign bank and brokerage accounts, many foreign pension accounts, and foreign-branch accounts of US banks. A US branch of a foreign bank does not count. The currency does not matter either: a USD account held abroad still counts toward your total.

Do I file an FBAR for an account I only have signature authority over?

Ownership is not the only trigger for an FBAR filing. You must report accounts where you have only signature authority, such as a corporate account for your employer or an aging parent's account. You must file even if you have no financial interest in the funds.

How does a joint account count toward the $10,000 threshold?

If you hold an account jointly with a spouse or business partner, the full value of the account counts toward your threshold. You do not divide the balance in half for reporting purposes.

Do I have to file an FBAR if I owe no US tax?

The FBAR is strictly informational. No tax is due on the report itself. Even if you use the Foreign Earned Income Exclusion (Form 2555) to exclude up to $130,000 (for 2025) of foreign earned income, your FBAR obligation remains unchanged. Alternatively, if you claim the Foreign Tax Credit (Form 1116), you still must file the FBAR. You can read more in our guide on why you must file even if you owe no tax.

Is the FBAR filed with my tax return?

FinCEN Form 114 is not filed with the IRS alongside your tax return. It must be submitted electronically through the BSA E-Filing System. While the deadline is April 15, there is an automatic extension to October 15 (no request is needed). The FBAR also does not replace the FATCA requirement. Form 8938 is a separate filing with higher, different thresholds that is filed with your 1040. One does not replace the other.

What is the penalty for not filing an FBAR?

Penalties are structured around intent. For non-willful violations, the maximum penalty is $16,536 (adjusted for inflation in 2025). Following the 2023 Supreme Court decision in Bittner v. United States, this non-willful penalty is applied per report (per year), not per account. If the violation is willful, the penalty is much steeper: the greater of $165,353 (2025 inflation-adjusted) or 50% of the account balance, per year.

How would the IRS find out about my foreign accounts?

Foreign banks report their US account holders directly. Under FATCA and the intergovernmental agreements built on it, financial institutions in most countries identify US customers and report their reportable accounts, either to their own tax authority for onward transmission or to the IRS. This happens as a matter of routine, not because anyone has opened an investigation into you. How the IRS finds expats who have not filed covers the mechanism in more detail.

Reporting is not quite universal. A bank may leave out an individual's depository accounts when they total $50,000 or less at that institution, though many report them anyway rather than track the exception. That gap is a thin thing to plan around. Your obligation starts at $10,000 aggregated across every institution and every country, which is far below where the bank exception bites, so a handful of small accounts can be fully reportable by you and still sit under the threshold at which any single bank reports them. Whether a bank filed is not the test. Your obligation does not depend on it, and neither does willfulness.

There is also the paperwork you sign yourself. A bank asks you to certify your tax status when you open an account, and a US citizen or resident certifies on Form W-9. Form W-8BEN is the form a non-US customer signs. Signing one to pass as a foreign customer is a false certification, and strong evidence that a later failure to report was willful.

The heavier consequence is what the decision does to your own position. Everything above about non-willful treatment, including the per-year cap and the streamlined procedures, rests on the failure being non-willful. Reading the rules and then choosing not to report is the fact that moves a case from one category to the other. The streamlined procedures require you to certify non-willfulness under penalties of perjury, so that route is not available to someone who decided deliberately. Choosing deliberately does not only raise the penalty ceiling. It forfeits the inexpensive way back.

How do foreign business accounts and taxes interact?

Two more filings catch digital nomads and expat business owners. If you operate a foreign disregarded entity or a foreign branch (the IRS position since 2018 can reach a foreign sole proprietorship), you must file Form 8858. If you are a US shareholder of a foreign corporation (a nomad's foreign LLC or company can be a CFC), you must file Form 5471, which carries potential net CFC tested income (NCTI, formerly GILTI) tax exposure.

The accounts held by these foreign entities often require FBAR reporting. And while the FEIE excludes income from income tax, it does not reduce self-employment tax. The US self-employment tax is 15.3% on 92.35% of net self-employment earnings (12.4% Social Security capped at the wage base plus 2.9% Medicare uncapped). This applies from $400 of net earnings. Totalization agreements (in about 30 countries) can exempt US self-employment tax via a Certificate of Coverage. However, most digital-nomad hubs (such as Thailand, Mexico, Indonesia, and Ecuador) have no totalization agreement, so the full 15.3% applies. You can compare your options using our FEIE vs FTC calculator or check specific country guides.

What should you do if you are behind on your FBARs?

Two routes exist, and which one fits depends on whether your tax returns are behind as well as your FBARs. Both assume the failure was non-willful, and the Streamlined route asks you to certify that under penalties of perjury, so eligibility is worth confirming before you file rather than after.

• Streamlined Foreign Offshore Procedures: This program requires filing three years of delinquent tax returns and six years of FBARs for non-willful taxpayers. Learn more about Streamlined filing.
• FBAR-only late filing: if your returns are complete and all income was reported, you can still file the missed FBARs directly. Note the IRS withdrew its published Delinquent FBAR Submission Procedures on 1 July 2026, so penalty relief on this path is discretionary and depends on documented reasonable cause.
