FBAR Filing Checklist: Documents and Information You'll Need

Before You Start

Gathering the right information ahead of time turns FBAR filing into a 20-minute task instead of an afternoon of digging through statements. Here's what to have on hand before you open the BSA E-Filing System.

Information Needed for Each Account

For every foreign financial account that counts toward your $10,000 aggregate threshold, gather:

1. Financial institution name and address. The full legal name and physical address of the bank or brokerage.
2. Account number or identifier. Whatever unique identifier the institution uses — account number, policy number, or similar.
3. Account type. Bank, securities, or "other" (which covers things like foreign mutual funds or certain pension accounts).
4. Maximum value during the year. The highest balance the account reached at any point in the calendar year — not the year-end balance and not the average.
5. Joint owner details. If the account is jointly held, the name, address, and identifying number of any co-owner.

Finding the "Maximum Value" Correctly

This is the single most common mistake in FBAR preparation. Filers often report the December 31 balance out of habit, carried over from tax-return thinking. The FBAR instead wants the highest balance the account held at any point during the year, which may have occurred in March, or July, or any other date — not necessarily year-end.

A reasonable approach is to review monthly or quarterly statements and identify the single highest balance shown across all twelve months. Reasonable estimates are permitted when the exact figure isn't readily available, but should be based on the best information you can obtain.

Converting to U.S. Dollars

Account values must be reported in U.S. dollars. The standard approach is to use the U.S. Treasury's year-end exchange rate for the relevant currency, applied to the maximum value determined in the step above — even if that maximum value occurred mid-year. FinCEN's instructions specify which published rate to use; when no Treasury rate is available for a given currency, another verifiable exchange rate source may be used, with that source documented for your records.

The Filing Steps, Start to Finish

1. Go to FinCEN's BSA E-Filing System and select the individual (not institutional) FBAR filing option, unless you're filing on behalf of an entity.
2. Enter your identifying information: name, address, and Social Security Number or ITIN.
3. Add each qualifying foreign account, entering the institution details, account type, and maximum converted value.
4. Indicate joint ownership where applicable, including co-owner details.
5. Review every entry — the system does not auto-check for common data-entry mistakes like transposed account numbers.
6. Submit electronically and save the confirmation. There is no filing fee.

After You File

Keep your confirmation of submission along with the underlying account statements you used to calculate maximum values — supporting records are generally worth retaining for at least five years given the FBAR recordkeeping expectations tied to the Bank Secrecy Act. If you discover an error after submitting, an amended FBAR can be filed through the same system.
