FBAR Calculator

Add your non-US accounts and their highest balance during the year. This works out the combined maximum value in US dollars and tells you whether you cross the $10,000 threshold for filing an FBAR (FinCEN Form 114), using the official US Treasury year-end exchange rate.

Your foreign accounts

💡 Don't forget US-dollar accounts held at non-US institutions — a balance in Wise, Revolut, or a foreign bank's USD account is still a foreign account. Add it and choose "US Dollar (non-US bank)" as the currency. (A USD account at a US bank is not foreign — leave that out.)

Now actually file it — with Taigan Bridge

This calculator gives you the number. Taigan Bridge's FBAR module — a full year-by-year FinCEN 114 tracker — does the whole job. Add your own Claude API key and it reads your bankbooks (通帳) and account statements straight from photos or PDFs — handling 和暦 era dates, 合算 summary rows, and fixed-deposit lifecycles — pulls every account and filer into the tracker at the official Treasury year-end rates, and walks you line by line through FinCEN Form 114 and the related paperwork (the Form 114a spouse authorization, a late-filing explanation, and more). It organizes everything; you still file. And it all stays on your device — nothing is uploaded.

Before you rely on this

Use each account's highest balance at any point during the year, not the year-end balance — a single high-water moment counts.
The $10,000 test is the combined total across all your foreign accounts, per person — not per account.
US dollars in a foreign account still count. FBAR is about where the account is, not the currency — a USD balance at Wise, Revolut, or a foreign bank is foreign. Enter it as "US Dollar (non-US bank)."
Joint accounts: each US-person owner generally reports the account's full maximum value, not a share.
A single large transfer can push you over the line for the year even if you spend it and end near zero.
This is an estimate to help you decide and prepare. The FBAR is filed with FinCEN through the BSA E-Filing System, separately from your tax return.
