Filing an FBAR sounds bureaucratic and is actually one of the faster filings in the US system: a short electronic form, submitted free of charge, confirmed by email within minutes. This walkthrough covers everything from the documents to have open before you start, to the exact sections of FinCEN Form 114, to the confirmation you must keep afterward. The official entry point is FinCEN's FBAR page, which routes to the BSA E-Filing System.
Before you start: the 15-minute information gathering
Have this open in front of you for each reportable account (see which accounts qualify):
| Item | Where to find it |
|---|---|
| Financial institution name and full mailing address | Any statement; the bank's "contact" page |
| Account number or other designation | Statement or online banking |
| Type of account | Checking, savings, brokerage, custodial, other |
| Maximum value during the year, in USD | Statement history + Treasury exchange rate |
| Joint owners' names and addresses (if any) | Account agreement |
| Whether you hold it as owner or signature-authority-only | Your relationship to the account |
Also ready: your SSN or ITIN (required) and, if filing jointly on a spousal account, your spouse's identifying details. If any account was jointly held, note the co-owner — the form asks.
The filing, step by step
1. Get to the real form. Go to fincen.gov/report-foreign-bank-and-financial-accounts and follow the link to BSA E-Filing. Two warnings: the filing is free — avoid commercial sites charging for "FBAR filing services" — and make sure you're on a .gov domain before entering your SSN.
2. Choose the individual filing path. Individuals can file directly without registering. Institutions and high-volume filers use registered accounts; you almost certainly want "File as an individual."
3. Select FinCEN Form 114 (FBAR), the correct year. Pick the form version matching the calendar year of the accounts, not the current date. Filing for 2025 accounts in 2026 means selecting the 2025 form year.
4. Part I — Filer information. Your name, SSN/ITIN, address. If you are filing for a jointly held spousal account with your spouse identified as a joint owner, the form's structure handles both of you here and at the account level.
5. Part II — one entry per account. For each account: institution name and address; account number or other designation; type; maximum value in whole US dollars; joint-owner details if applicable. Four notes from the field:
- Maximum value means the year's peak, not the closing balance (see aggregation and maximum-value rules). Rounding is acceptable — the form's instructions expressly permit reasonable rounding.
- Signature-authority-only accounts go here too, flagged as such, with the full maximum value.
- Currency conversion: use Treasury's yearly rate as your default; document whatever rate you use for your records.
- Every reportable account gets its own entry, including the small ones — once the aggregate crosses $10,000, all accounts are listed.
6. Part III — signature authority only? If some reported accounts are signature-authority-only (work accounts, elderly parents' accounts), this section captures the details of your authority.
7. Review and submit. The system validates formats (names without punctuation quirks, addresses, whole-dollar values). Fix what it flags, submit, and watch for the confirmation email containing your BSA Identifier.
8. File any additional years separately. Catching up on missed years? Each year is its own Form 114 submission. See filing late in 2026 for the full catch-up sequence, including your reasonable cause statement.
After filing: two retention jobs
- Save the confirmation email — the BSA Identifier is your proof of timely filing. It belongs in your FBAR records folder alongside the account statements.
- Keep the underlying records five years from the filing date.
The errors that cause rejections or trouble
- Wrong form year — filing 2025 accounts on the 2026 form. Always match the calendar year of the accounts.
- Maximum value = closing balance. The spike in March is what the form wants.
- Forgetting the signature-authority account. Access you rarely use is still access; if you can direct funds, report.
- Listing only the biggest account. Once over the threshold, every qualifying account gets an entry.
- Personal data on a lookalike site.
.govor nothing. - Assuming your tax preparer filed it. Unless your engagement letter expressly includes FBAR preparation (most don't — it's a FinCEN filing, not a tax return), they didn't.
If something goes wrong
Rejected submission: correct the flagged fields and resubmit — no penalty attaches to a rejected attempt, only to a missed deadline. Filed with an error after acceptance (wrong value, missing account): file an amended FBAR for that year via the same system; amendments are routine and far better than silence. Realized you missed years entirely: start with the late-filing guide — and remember the automatic extension rules may mean you're not even late.

Frequently asked questions
Do I need an account to file an FBAR through BSA E-Filing?
No. Individual filers can file FinCEN Form 114 directly through the BSA E-Filing System without registering for an account. Registration is only needed for institutional filers or those filing in volume. You file as an individual and receive a confirmation with a BSA Identifier by email.
How long does it take to file an FBAR online?
Most first-time filers with one or two accounts finish in 30 to 60 minutes, most of it spent gathering account details — institution names and addresses, account numbers, and each account's maximum value in US dollars. The form itself is short.
What do I do if my FBAR is rejected?
Rejections usually stem from formatting issues (names, addresses, or values) or an invalid TIN. The system identifies the failing fields; correct them and resubmit. An FBAR is not filed until you receive the acceptance confirmation email with the BSA Identifier.
Where do I find the FBAR form?
The official entry point is FinCEN's 'Report Foreign Bank and Financial Accounts' page at fincen.gov, which links to the BSA E-Filing System. Beware of commercial lookalike sites that charge for filing; the government filing is free.
Who files FinCEN Form 114 — the IRS or FinCEN?
FinCEN, always. The form is called FinCEN Form 114 for a reason. Even though the IRS enforces FBAR violations, the filing itself is made to FinCEN's BSA E-Filing System and never attached to your tax return.
