FBAR for US Expats: Who Must File, the $10k Rule, and How to File FinCEN 114 Correctly

"Do you all file your FBAR yourselves?" It's the first question almost every new expat asks. Here's the honest answer — plus exactly how the $10,000 rule works and what to do if you've missed a few.

· 10 min read

If you're a US citizen or green card holder living abroad, the FBAR is probably the first piece of US tax bureaucracy that genuinely confuses you. It's not part of your tax return, it goes to a different agency, and the $10,000 number everyone quotes is more subtle than it sounds.

The good news: once you understand it, the FBAR is one of the more straightforward obligations an expat has — and for many people, it's free to file yourself. This guide covers who has to file, how the threshold really works, how to file FinCEN Form 114, and what to do if you're behind.

This is general information, not tax advice. The mechanics below are the common case; unusual account structures and signature-authority situations can change the answer.

What the FBAR actually is (and isn't)

FBAR stands for Report of Foreign Bank and Financial Accounts, filed on FinCEN Form 114. Two things surprise people immediately:

  • It goes to FinCEN (the Treasury's financial-crimes network), not the IRS — it's an anti-money-laundering disclosure, not a tax form. You don't owe any tax because of an FBAR; it's purely informational.
  • It's filed separately from your tax return, electronically through the BSA E-Filing system — not attached to your Form 1040.

So you can owe $0 in US tax and still be required to file an FBAR every year. Filing it and reporting the same accounts on Form 8938 (which does go to the IRS) are two different obligations that often both apply — more on that distinction below.

The $10,000 rule, precisely

You must file an FBAR if the aggregate value of all your foreign financial accounts exceeds $10,000 at any point during the calendar year. Every word of that matters:

  • Aggregate — you add up all your foreign accounts. Five accounts holding $3,000 each ($15,000 total) crosses the line, even though no single account does.
  • At any point — it's the highest balance during the year, not the year-end balance. One day above $10,000 triggers the filing for the whole year.
  • $10,000, not inflation-adjusted — this threshold has been fixed for decades, so more people cross it every year.

And critically: once you cross the threshold, you report every foreign account — including the small ones — not just the accounts over $10,000. The threshold is a trigger; the report is comprehensive.

Not sure if you cross it — or whether Form 8938 also applies? The free FBAR / Form 8938 threshold checker takes your balances and filing status and tells you which of the two you're required to file this year.

Who has to file, and which accounts count

Any US person — citizen, green card holder, or US resident — with a financial interest in, or signature authority over, foreign financial accounts that cross the threshold. The signature-authority part catches people off guard: you may have to report an account you don't own but can sign on, such as an employer's account or a relative's account you help manage.

Accounts that typically count:

  • Foreign bank accounts (checking, savings, term deposits).
  • Foreign brokerage and investment accounts.
  • Foreign mutual funds and many pooled investment accounts.
  • Certain foreign pensions and cash-value foreign life insurance.

Directly held foreign real estate does not go on an FBAR (it's not a financial account), and foreign-held physical cash or precious metals generally don't either. The treatment of crypto held on foreign exchanges is still evolving — FinCEN has signaled future reporting — so if a meaningful part of your holdings is crypto on a non-US platform, treat it as a watch-this-space item and confirm the current rule.

How to file FinCEN 114 (and the deadline)

  1. Gather, for each foreign account: the institution name and address, the account number, and the maximum value during the year.
  2. Convert each maximum value to US dollars using the Treasury year-end exchange rate.
  3. File electronically through the BSA E-Filing system (it's free).
  4. The deadline is April 15, with an automatic extension to October 15 — you don't have to request the extension.

That's genuinely it. There's no payment, no schedule, no calculation of tax — just an accurate list of accounts and their peak values.

"Do you all file your FBAR yourselves?" — the honest answer

Yes — plenty of expats file their own FBARs, and for a simple case (a couple of bank accounts, clear balances), that's a perfectly reasonable thing to do. The form is free and the mechanics are manageable. We'd rather tell you that than pretend otherwise.

Where it stops being a do-it-yourself job is when the FBAR is the easy part of a harder picture:

  • you have many accounts, or signature authority over accounts you don't own;
  • those accounts hold foreign funds (PFICs), which drag in Form 8621 and real tax — see our PFIC guide;
  • you've missed prior-year FBARs and need to come into compliance correctly.

FBAR penalties — and why you shouldn't panic

FBAR penalties look terrifying on paper, which is why "FBAR penalties?" is such a common forum title. For context:

  • Non-willful violations carry a penalty of roughly $10,000 per violation (inflation-adjusted) — but this is for genuine non-filing, and it's routinely abated for reasonable cause.
  • Willful violations are far worse: up to the greater of $100,000 or 50% of the account balance. This is aimed at deliberate hiding, not honest mistakes.

Here's the part that should lower your blood pressure: if you simply didn't know, the Streamlined Foreign Offshore Procedures waive FBAR penalties entirely for non-willful expats. The penalty regime exists, but the path around it is exactly the kind of honest-mistake situation most expats are in.

What if I've missed FBARs from previous years?

Don't just start filing this year and quietly ignore the gap. Your route depends on what else you missed:

  • Only FBARs missed, but all returns filed and income reported? The IRS Delinquent FBAR Submission Procedures let you e-file the late reports with a reason, penalty-free, as long as you're not under exam.
  • Missed returns too? That's the streamlined territory — three years of returns plus six years of FBARs. Our Streamlined eligibility checker sorts out which path is yours, and the back-taxes guide walks through it.

Check what you owe FinCEN — and the IRS

FBAR is rarely the whole story: the same foreign accounts often trigger Form 8938 and, if they hold foreign funds, Form 8621. atamatax handles the whole stack in one flow — FBAR for FinCEN, 8938 and 8621 with your return — so you don't have to assemble it piece by piece.
