The FBAR isn’t an IRS form—it’s a report you file with the Financial Crimes Enforcement Network (FinCEN), which is part of the U.S. Treasury Department. Think of FinCEN as the financial intelligence unit; they’re looking for money laundering and tax evasion.
The rule is deceptively simple: If you have a financial interest in or signature authority over a foreign financial account, and the total value of all those accounts exceeds $10,000 at any point during the calendar year, you must file an FBAR.
Notice that: at any point. It doesn’t matter if the balance was $10,001 for just one day and then you spent it all. You have to file. It’s an annual calendar year report, due April 15, with an automatic extension to October 15.
The definition is broad. It includes:
- Bank accounts (checking, savings, time deposits)
- Securities or brokerage accounts
- Mutual funds
- Certain types of foreign life insurance or annuity policies with a cash value
- Cryptocurrency accounts held with a foreign centralized exchange (this is a gray area but the conservative position is to report it)
- Accounts held at foreign branches of U.S. banks (Yes, your Chase account in London counts as foreign)
Key Concept – Signature Authority: This is where people get blindsided. You must file an FBAR not only for accounts you own, but also for accounts you can control, even if there’s no financial benefit to you.
- Example: You are the treasurer of a U.S. non-profit that has an operating account in Canada. You have signature authority. You must file an FBAR for that account and check the box stating you have only signature authority.
You add up the maximum value of each foreign financial account, in U.S. dollars, at any time during the year. You use the foreign exchange rate from the day you determine each account’s maximum value.
- Account 1 (UK): Max value £8,000 (when GBP/USD = 1.25) = $10,000
- Account 2 (Japan): Max value ¥500,000 (when USD/JPY = 100) = $5,000
- TOTAL: $15,000 → FBAR REQUIRED.
Even though neither account alone hit $10,000, the aggregate did. You must report both accounts on the FBAR.
The penalties are not tied to tax owed; they’re tied to the value of the account.
- Non-Willful Violation (You didn’t know): Up to $10,000 per violation.
- Willful Violation (You knew or should have known): The greater of $100,000 or 50% of the account’s balance at the time of the violation. This penalty can be applied per year. An unreported $1 million account could trigger a $500,000 penalty for one year. It can exceed the account’s total value.
The IRS (which enforces FBAR on behalf of FinCEN) has been aggressive with these penalties. “I didn’t know” is an argument, but it’s not a guaranteed get-out-of-jail-free card.
- Who Files: U.S. Persons. This includes citizens, residents (green card holders, those meeting the Substantial Presence Test), and entities formed in the U.S. (LLCs, corporations, partnerships, trusts, estates).
- How to File: ONLINE ONLY. You file through the BSA E-Filing System on the FinCEN website. You cannot paper-file an FBAR. You do not attach it to your tax return.
- Deadline: April 15, with an automatic extension to October 15. No form is needed for the extension; it’s built-in.
- Information Required: For each account, you need:
- Name on the account
- Account number
- Name and address of the foreign bank/financial institution
- Type of account
- The maximum value during the year (in USD)
Frequently Asked Questions (FAQ)
I have a foreign account, but my spouse is the primary owner. Do I need to file?
It depends on the ownership structure. If the account is jointly owned with your spouse, you have a financial interest and must report it. If you have signature authority but no ownership (e.g., you can sign on your spouse’s individual account), you must file and check the “signature authority” box. There is an exception for spouses if all the accounts are reported on the other spouse’s FBAR, you have no personal accounts, and you file a joint tax return.
Do I report accounts I own through a U.S. entity, like my LLC?
Maybe. Both you AND the entity might have to file. If your U.S. LLC owns a foreign account, the LLC must file its own FBAR. If you own more than 50% of the LLC, you also have a “financial interest” in its accounts and must report them on your personal FBAR. This is a common double-reporting situation.
My foreign pension fund (like a Canadian RRSP or UK ISA)—is that an FBAR account?
Usually, yes. If it’s a financial account maintained by a foreign financial institution, it’s reportable. Conservative practice is to include it.
What if I can’t get the exact maximum balance? My foreign bank only gives monthly statements.
Use a reasonable, good-faith estimate. If your December statement shows $12,000 and your June statement shows $9,000, your maximum value for the year is at least $12,000. Document your method. The IRS expects you to make a diligent effort.
I missed filing FBARs for several years. What should I do?
You need to get into compliance, but carefully. The IRS has a Streamlined Filing Compliance Procedures program for taxpayers who can certify their failure was “non-willful.” This allows you to file 6 years of delinquent FBARs and 3 years of amended tax returns (if needed) without facing the standard penalties. DO NOT just start filing old FBARs without understanding this program, as you could accidentally make yourself ineligible. Professional guidance is critical here.
How is this different from Form 8938 (FATCA)?
They are separate and cumulative requirements.
FBAR: Reports foreign financial accounts to FinCEN. Threshold: $10,000 aggregate at any time.
Form 8938: Reports foreign financial assets (broader than accounts) to the IRS. Threshold: $50,000+ depending on residency/filing status.
You will likely file both if you have significant foreign assets.
Is there a minimum age? Does my child have to file?
Yes, a minor child is subject to the FBAR rules. The parent or guardian must file the FBAR on the child’s behalf. If the parent has signature authority over the child’s account, the parent must also report that account on their own FBAR.
The FBAR is the most commonly violated international reporting rule because the $10,000 threshold is so low. People forget about an old inherited account abroad, a business account they have signing power for, or a joint account with a non-U.S. relative. The penalties are financially devastating. If you have any connection to a foreign account, the first step is to check your statements, add up the peaks, and assume you need to file unless the math clearly says otherwise. And if you’re behind, don’t stick your head in the sand—get professional help to use the IRS’s amnesty programs before they come find you.
