Connect on LinkedInFor FBAR purposes, aggregate account value is the total of the maximum values of all your reportable foreign financial accounts during a calendar year, after converting them to U.S. dollars.
Why it matters for U.S. expats
A U.S. person must file an FBAR when the aggregate account value of their foreign financial accounts exceeds $10,000 at any point during the calendar year.
The threshold applies across all reportable accounts, not separately to each account. Similar calculations apply to Form 8938, but its assets and reporting thresholds are different.
Common questions
1. What does aggregate account value mean for FBAR reporting?
It is the combined maximum value of all your reportable foreign financial accounts during the calendar year.
2. How do you calculate aggregate account value for an FBAR?
Find each account’s highest value during the year, convert it to U.S. dollars, and add the converted maximum values together.
3. Is the $10,000 FBAR threshold per account or combined?
It is combined. Several accounts below $10,000 can still trigger an FBAR when their aggregate account value exceeds $10,000.
4. Do I report every foreign account if the combined value exceeds $10,000?
Yes. Once the threshold is exceeded, you report every qualifying foreign account, including accounts with small balances.
5. What exchange rate should I use to calculate aggregate account value?
Use the U.S. Treasury exchange rate for the final day of the calendar year. If no Treasury rate is available, use another verifiable rate and record its source.
6. Does a joint foreign account count toward aggregate account value?
Yes. You include the account’s full maximum value rather than only your share of the balance.
7. Do accounts with signature authority count toward aggregate account value?
Yes. Foreign accounts over which you have signature or other authority may be reportable even when you do not own the funds.
8. Is aggregate account value calculated the same way for FBAR and Form 8938?
No. Form 8938 covers a broader range of foreign financial assets and has different thresholds based on filing status and whether the taxpayer lives abroad.
