10 Common FBAR Filing Mistakes (and How to Avoid Them)
1. Using the Wrong Exchange Rate
The mistake: Converting foreign currency to USD using Google, your bank's rate, or the rate on the day of maximum balance.
The rule: Use the Treasury Department's end-of-year exchange rate (December 31 rate for the reporting year). Not your bank's rate, not the spot rate, not the rate on the date of maximum balance.
FBAR File automatically applies the correct Treasury rate for the tax year you're filing.
2. Reporting Year-End Balance Instead of Maximum Value
The mistake: Entering your December 31 balance.
The rule: Report the highest balance the account reached at any point during the calendar year. Check all 12 monthly statements and use the highest figure. If your account hit $50,000 in March but ended the year at $5,000, report $50,000.
3. Forgetting About Closed Accounts
The mistake: Skipping an account because you closed it mid-year.
The rule: If the account was open at any point during the calendar year, it must be reported. Closed in January? Report it with the maximum value from January.
4. Not Including Joint Accounts
The mistake: Assuming your spouse handles joint accounts or that you only report your "half."
The rule: Report the full maximum value of every joint account where you have a financial interest. Both spouses may have a filing obligation if both are US persons.
5. Confusing the $10,000 Threshold
The mistake: Thinking each account must independently exceed $10,000.
The rule: The $10,000 threshold is the aggregate of all foreign accounts combined. Five accounts with $2,500 each = $12,500 total. You file.
6. Leaving Out Non-Bank Accounts
The mistake: Only reporting bank accounts and forgetting about brokerage accounts, insurance policies with cash value, or retirement accounts abroad.
The rule: All "financial accounts" at "financial institutions" outside the US must be reported. This includes securities accounts, mutual fund accounts, and certain insurance policies.
7. Wrong Account Number Format
The mistake: Including dashes, spaces, or country prefixes inconsistently.
The rule: Enter the account number as your bank identifies it. For IBANs, include the full IBAN. Consistency matters — use the same format your bank uses on statements.
8. Filing Late Without Realizing It
The mistake: Assuming the FBAR follows the same extension as your tax return.
The rule: The FBAR deadline is April 15, with an automatic extension to October 15. This is separate from your tax return extension. If you filed a tax extension to October 15 and thought that covered the FBAR — it did by coincidence, but not by rule.
9. Not Filing Because Balances Were "Close" to $10,000
The mistake: Estimating account values and deciding you're under the threshold without checking actual statements.
The rule: Calculate precisely. Get your statements. Factor in salary deposits, incoming transfers, and temporary spikes. Many filers who think they're under $10,000 discover they exceeded it for a day or two during the year.
10. Assuming Your CPA Filed It
The mistake: Assuming FBAR filing is included in your tax preparation.
The rule: The FBAR is a separate filing with a separate agency (FinCEN, not the IRS). Many CPAs charge separately for FBAR preparation, and some don't handle it at all. Always confirm explicitly.
The Fix
Most of these mistakes come from not understanding how the FBAR differs from a tax return. It's a separate form, filed with a separate agency, using separate rules. FBAR File is designed to prevent these errors — we validate your data, apply correct exchange rates, and generate a form that FinCEN accepts.
