Assumptions behind this calculator
  • The FBAR applies when the aggregate of all foreign accounts exceeds $10,000 at any point in the calendar year.
  • Joint accounts count at full value for each US-person holder; signature-authority accounts count too.
  • Convert each balance to US dollars using the Treasury year-end rate for the reporting year.
  • Five inputs are shown for simplicity — with more accounts, sum the rest into one line; the threshold logic is identical.
  • Figures are based on 2025 (US) rates from FinCEN — Report of Foreign Bank and Financial Accounts (FBAR), IRS — About Form 8938.

How the $10,000 threshold really works

Three words do all the damage: aggregate, any point, and balance. Aggregate means every foreign account added together, not any single one. Any point means the highest balance during the year, even for a day. And balance means money held, not income earned — a dormant account still counts in full.

That combination pulls in far more people than the number suggests. A current account, a savings pot and a workplace pension clear $10,000 between them without any single account looking significant. Transfers between your own accounts can even double-count, because each account reports its own peak.

Which accounts belong in the total?

  • Bank and building society accounts — current, savings, fixed-term
  • Cash ISAs and stocks-and-shares ISAs
  • Workplace and personal pensions in most cases
  • Joint accounts, counted at full value
  • Accounts you can sign on for an employer, parent or club, even without owning a penny of them

What happens if you're over the line?

You file FinCEN Form 114 electronically — separate from the tax return, free, and extended automatically to 15 October. The filing raises no tax; the penalties for skipping it are the problem. Missed past years usually route through the streamlined procedures or the delinquent FBAR process — our Streamlined Filing Eligibility Checker shows which fits.

The full rulebook, penalties included, lives in our guide to FBAR deadlines and penalties, and our FBAR & FATCA reporting service handles the filings end to end. Ask us a question if any account leaves you unsure — pensions and trusts are exactly where doubt is sensible.

Common questions about this tool

Does the FBAR threshold apply per account or in total?
In total. Add the highest balance of every foreign account together, and once that aggregate exceeds $10,000 at any point in the year, every account gets reported — including the small ones. A single account over the line has the same effect for the same reason.
Do UK pensions count toward the FBAR?
Workplace and personal pensions are generally treated as reportable foreign financial accounts, and the cautious practice is to include them. Valuation uses the year-end statement where a daily maximum is impractical. State Pension entitlements are not accounts and stay outside the calculation.
How do I convert pounds to dollars for the FBAR?
Use the US Treasury's year-end exchange rate for the reporting year, applied to each account's highest balance. The form asks for values rounded up to the next dollar. Keep a note of the rate used, because consistency across years is what examiners look for first.
Is there tax to pay when I file an FBAR?
No — the FBAR is an information report to FinCEN, not a tax form, and filing it costs nothing. Any tax on interest or gains flows through the tax return separately. The FBAR's teeth are its penalties for non-filing, which is why the threshold check matters.
What if I only exceeded $10,000 for one day?
The test is any point in the calendar year, so a single day over the line creates the filing duty for that year. House-purchase money passing through an account is the classic example — briefly held, long gone, and still fully reportable for that year.
I missed FBARs for past years — what now?
Do not quietly back-file. If your tax returns were otherwise correct, the delinquent FBAR procedures accept late reports with a reasonable-cause note, generally penalty-free. Where returns were missed too, the streamlined procedures cover both. Choosing the right door first protects the penalty relief.
