Foreign bank accounts are reported once a year on FinCEN Form 114, the FBAR, filed electronically through the BSA E-Filing System — not with a tax return. The requirement applies when the combined value of all foreign financial accounts passes $10,000 at any point in the year. The report is due April 15, with an automatic extension to October 15.
The form has a fearsome reputation and a modest reality. It asks for no tax computation and produces no bill. It is an information report — a list of accounts, their peak balances and where they are held — sent to the Financial Crimes Enforcement Network, a Treasury bureau that is not the IRS. What follows is the filing, in the order the rules present it.
| Filing route | Who uses it | What it needs | How it works |
|---|---|---|---|
| Online form | Individuals filing their own report | A browser and the account details | Completed and submitted in one session on the BSA E-Filing System — individual filers do not register for an account |
| Offline PDF | Filers who want to work in stages | The Form 114 PDF and a current Adobe Reader | Filled in offline, then uploaded and submitted through the same system |
| Third party with Form 114a | Spouses and paid preparers | A signed Form 114a kept on file | The preparer or spouse submits the report — Form 114a records the authorization and is retained, not sent to FinCEN |
Who files, and which accounts count
Every United States person — citizen, green-card holder or tax resident — files the FBAR for any year in which the combined value of their foreign financial accounts exceeds $10,000 at any moment, however briefly. The rule is 31 CFR 1010.350, and it reaches accounts the filer owns and accounts the filer merely controls — the regulation calls these financial interest and signature authority.
The threshold is aggregate, not per account. Three accounts of $4,000 each cross it together, and an account that held $12,000 for a single afternoon crosses it alone. Reportable accounts include more than checking and savings:
- Bank accounts — checking, savings, time deposits — held at institutions outside the United States, including the foreign branches of US banks
- Securities and brokerage accounts maintained with a foreign financial institution
- Foreign-issued life insurance or annuity contracts with a cash value
- Foreign mutual funds and similar pooled funds
- Accounts the filer does not own but can direct — an employer account with signature authority, or a joint account with a foreign spouse
The geography follows the institution, not the currency or the owner. A dollar account at a Lisbon bank is reportable; a euro account at a foreign bank’s branch inside the United States is not, under the same regulation.
Step 1 — pull one number for every account
The figure the form wants is each account’s maximum value during the calendar year, rounded up to the next whole dollar. FinCEN’s filing instructions accept periodic account statements as the basis for that figure, so the largest balance shown on the year’s statements serves. For each account, the form also asks for the institution’s name and address, the account number and the account type.
Foreign currency converts at the Treasury Reporting Rates of Exchange for December 31 of the year being reported — one published rate per currency, applied to the maximum balance. The rate table is published by the Bureau of the Fiscal Service and is the only rate source the filing instructions name.
Step 2 — pick the filing route
There are three routes to a filed FBAR, and all three end at the same place — FinCEN’s BSA E-Filing System. An individual filing a personal report uses the online form or the offline PDF without registering for a system account; registration is for institutions and batch filers. A spouse or a paid preparer files on another person’s behalf once that person signs Form 114a, which stays in the filer’s records.
One simplification exists at scale: a filer with a financial interest in 25 or more foreign accounts reports the number of accounts on the form and keeps the detailed information available on request, rather than itemizing every account.
Step 3 — complete and submit the form
The form runs in parts: filer information first, then Part II for accounts owned separately, Part III for jointly owned accounts, and Parts IV and V for signature-authority and consolidated filings. Spouses have a shortcut — one spouse may file a single FBAR covering both, provided every reportable account of the non-filing spouse is jointly owned and Form 114a is signed. When the accounts are not all joint, each spouse files separately.
Submission returns an acknowledgment with a BSA identifier — the proof the report exists. That confirmation belongs with the account records, because 31 CFR 1010.420 requires the underlying details — account numbers, institutions, maximum values — to be kept for five years from the report’s due date.
The deadlines — and the extension nobody applies for
The FBAR for a calendar year is due April 15 of the following year, and every filer who misses that date receives an automatic extension to October 15 — no request, no form, no fee. FinCEN’s due-date notice states the extension applies without any need to ask for it, which makes October 15 the practical deadline for most filers abroad.
One narrow group runs on a different clock: employees with signature authority over, but no financial interest in, their employer’s foreign accounts have had their deadline deferred repeatedly by FinCEN notice — most recently to April 15, 2027. And the tax return is not fully out of the picture — Schedule B of Form 1040 asks every filer whether a foreign account existed and whether a FinCEN Form 114 is required, so the two filings answer to each other even though they travel separately.
What happens if the report is late — or missing
A missed FBAR is a penalty matter under 31 USC 5321, not a tax deficiency. For non-willful violations the statute sets a base penalty of $10,000, adjusted annually for inflation — and the Supreme Court held in Bittner v. United States (2023) that the non-willful penalty applies per unfiled report, not per account, so one late year is one violation however many accounts it covered. The statute also carries a reasonable-cause exception for non-willful failures.
Willful violations sit in a different category — a statutory base of the greater of $100,000 or half the account balance, with criminal exposure in the extreme cases the case law describes. The filing system itself anticipates lateness: a late FBAR is submitted through the same BSA E-Filing System, and the form includes a field for selecting the reason the report is late.

Common questions
- Do I file the FBAR with my tax return?
- No. FinCEN Form 114 goes to the Financial Crimes Enforcement Network through the BSA E-Filing System, entirely separate from Form 1040. The two filings only touch at Schedule B, which asks whether a foreign account existed and whether a FinCEN Form 114 is required. Filing a tax return does not file an FBAR, and an FBAR settles no tax.
- Does the $10,000 threshold apply to each account or to all of them together?
- To all of them together. The threshold is the combined value of every foreign financial account at any single point in the year, so three accounts of $4,000 each cross it as surely as one account of $12,000. Once it is crossed, every foreign account gets reported — including the small ones.
- My accounts only went over $10,000 for a few days — do I still file?
- Yes. The rule under 31 CFR 1010.350 turns on the highest combined value at any moment in the calendar year, however briefly it stood there. An account that held $12,000 for a single afternoon triggers the filing for that year, even if the balance spent the rest of the year near zero.
- Do I owe tax on the accounts I report on an FBAR?
- Not because of the FBAR. FinCEN Form 114 is an information report — it carries no tax computation and produces no bill. Interest or gains the accounts earn are handled on the tax return under ordinary rules, but the report itself exists so that Treasury knows the accounts exist, nothing more.
- Do I have to report a joint account I share with my foreign spouse?
- Yes, where a United States person holds it. A joint account belongs on Part III of the form whoever the co-owner is, and a non-US spouse’s co-ownership does not remove it. One spouse may file a single FBAR for both only when every reportable account of the non-filing spouse is jointly owned and Form 114a is signed.
- What exchange rate do I use for accounts held in euros?
- The Treasury Reporting Rates of Exchange for December 31 of the year being reported, published by the Bureau of the Fiscal Service. One published rate per currency, applied to each account’s maximum balance for the year, rounded up to the next whole dollar. The filing instructions name no other rate source.
- What happens if I miss the April 15 FBAR deadline?
- Nothing, at first — every filer receives an automatic extension to October 15 with no request, form or fee, under FinCEN’s due-date notice. A report filed after October 15 is late; it still goes through the BSA E-Filing System, and the form includes a field for selecting the reason it is late.
- What is the penalty for not filing an FBAR?
- For non-willful violations, 31 USC 5321 sets a base penalty of $10,000, adjusted annually for inflation — and the Supreme Court held in Bittner v. United States that it applies per unfiled report, not per account. The statute carries a reasonable-cause exception. Willful violations carry a base of the greater of $100,000 or half the account balance.
- Does my foreign pension or life insurance count as an account?
- Often, yes. Foreign-issued life insurance and annuity contracts with a cash value are reportable, as are securities accounts and foreign mutual funds. The definition in 31 CFR 1010.350 reaches well past checking and savings — the question is whether a financial institution outside the United States maintains the account.
- I can sign on my employer’s foreign account but the money is not mine — do I file?
- Signature authority alone triggers the filing, under the same regulation that covers ownership, and the account is reported in the signature-authority part of the form. One deferral exists: employees with signature authority over, but no financial interest in, employer accounts have had their deadline pushed by FinCEN notice — most recently to April 15, 2027.
- Do I need to register for a BSA E-Filing account before I can file?
- No — individuals filing their own reports use the online form or the offline PDF without registering; registration is for institutions and batch filers. Submission returns an acknowledgment with a BSA identifier, and 31 CFR 1010.420 requires the account details behind the report to be kept for five years from the due date.
