Using Treasury year-end rates, checked November 2, 2026
FBAR Threshold Calculator
Enter the highest balance of each account outside the US, in its own currency. We convert at the official US Treasury rate for December 31 and add them up, as FinCEN instructs.
Quick answer
How do I work out the FBAR US$10,000 test?
A US person files an FBAR if the total value of their foreign financial accounts was over US$10,000 at any time in the year (IRS). To convert, FinCEN says to use the Treasury rate for the last day of the calendar year, or another verifiable rate if there is none (FinCEN). Adding each account's highest balance is the conservative way to test it, and whether an account produced income makes no difference.
The calculator
For each account outside the US, enter its highest balance in the year, in the account's own currency. Include accounts you have signature authority over.

Other things to check
- Due date. April 15, with an automatic extension to October 15 (IRS).
- Form 8938 is separate. If you live abroad, its thresholds are over US$200,000 at year end or US$300,000 at any time, and US$400,000 or US$600,000 on a joint return (Form 8938 instructions).
- Rates. Treasury publishes December 31 rates after the year ends, so the current year is not included. Use the latest year as a guide. The rates here are from the Treasury Reporting Rates of Exchange.
- Other currencies. Enter the value in US dollars, using a verifiable rate.

Common questions
Do I add the accounts together?
Yes. The test looks at the total value of your foreign financial accounts at any time in the year.
Do RRSPs and TFSAs count?
Accounts at financial institutions outside the US generally count, and whether an account produces taxable income does not change that. Your facts decide.
What rate do I use?
FinCEN says to use the Treasury rate for the last day of the calendar year. If there is none, use another verifiable rate and identify its source.
Is anything saved?
No. It runs in your browser, and your entries are not stored or sent.
