FBAR Reporting: A Guide for US Citizens Living in Europe
FBAR is the annual Treasury report for foreign financial accounts, and it can apply even when no additional income tax is due. If you are a US citizen or other US person living in Europe, the main rule is simple: if the aggregate value of your foreign financial accounts exceeded $10,000 at any point during the year, you may need to file FinCEN Form 114. The official IRS FBAR page confirms that the filing requirement covers both financial interest and signature or other authority over foreign accounts, and that the report is filed electronically through FinCEN rather than with your federal return. That makes FBAR easy to underestimate, because it feels separate from the tax return while still being part of overall US compliance.
What matters in practice is scope. Joint accounts, business signatory accounts, brokerage accounts, and some insurance or pension-type arrangements can all trigger review. The IRS also says FBAR is due April 15 with an automatic extension to October 15, and records generally must be kept for five years (IRS FBAR page). “The most expensive FBAR mistakes are usually omissions, not complicated legal disputes,” says Kari Foss-Persson, Esq., Managing Partner at Vinland Immigration. “People leave out a joint account, an employer signatory account, or an account they thought was too small to matter.”
FBAR is a reporting obligation, not an income tax. If your aggregate foreign accounts ever exceed $10,000 during the year, the filing is likely due even if the accounts never hold that amount at year-end.
What is the FBAR?
FBAR is FinCEN Form 114, a Treasury filing used to report foreign financial accounts held or controlled by US persons.
The IRS FBAR page states that FBAR is filed under the Bank Secrecy Act, electronically through FinCEN’s BSA E-Filing System, and not with your federal income tax return. That separate filing channel is one reason people forget it, especially when the account itself is already known to the bank under FATCA.
FBAR is not a tax on the account balance. It is a disclosure regime designed to tell the Treasury Department which foreign accounts you own or control.
Who must file?
You generally file when you are a US person with financial interest in, or signature authority over, foreign accounts that exceed $10,000 in aggregate.
The official IRS FBAR page says the threshold is measured on the combined value of all reportable foreign accounts at any point during the calendar year. It is not a per-account test and it does not depend on whether the account produced taxable income.
What accounts are reportable?
Reportable accounts can include far more than an ordinary checking account, especially where you have authority to move money for someone else.
- Bank accounts, savings accounts, and term deposits
- Securities and brokerage accounts
- Some foreign insurance or investment accounts
- Accounts over which you have signature or other authority
- Joint accounts with a spouse or business partner
The account does not need to be yours in the everyday sense for FBAR to matter. If you can control disbursements from an employer account, that authority alone may create a filing issue.
Filing deadline and automatic extension
FBAR is due in April, but the extension to October is automatic and does not require a separate form.
The IRS FBAR page says the annual deadline is April 15 following the year reported, with an automatic extension to October 15 if you miss the April deadline. That extension rule applies broadly and is separate from the filing deadlines for Form 1040.
You still should not treat October as the default if account information is hard to reconstruct. The longer you wait, the more likely it is that a joint account, closed account, or business account will be reported inconsistently.
What happens if you do not file?
Missing an FBAR can trigger serious civil penalties, and the willful versus non-willful distinction matters far more than most taxpayers expect.
In IRM 4.26.16, the IRS explains that non-willful violations can draw civil penalties and that willful violations may be penalized up to the greater of the inflation-adjusted statutory maximum or 50% of the account balance at the time of the violation. The same guidance stresses that facts, circumstances, and examiner discretion all matter.
That does not mean every late FBAR becomes catastrophic. It does mean you should decide on the corrective path before filing piecemeal amendments on your own.
How does FBAR differ from FATCA Form 8938?
FBAR and Form 8938 overlap in many cases, but they are different filings with different thresholds and different reporting scope.
| Feature | FBAR | Form 8938 |
|---|---|---|
| Filing threshold | Aggregate foreign financial accounts over $10,000 at any point during the year | Higher thresholds, including $200,000 single / $400,000 married filing jointly for taxpayers living abroad at year-end |
| Where filed | FinCEN via the BSA E-Filing System | Attached to your federal tax return |
| Penalties | Potentially much larger | Separate penalty regime under IRC 6038D |
| Account types | Foreign financial accounts only | Broader foreign financial assets, including some holdings not reported on FBAR |
If one filing applies, you should always check the other. Many expats in Europe end up needing both. Our tax compliance and cross-border tax practice areas cover both.
Common mistakes Europeans make
The most common FBAR errors involve leaving out accounts that feel secondary, temporary, or business-related rather than truly foreign.
People often miss joint accounts with a non-US spouse, accounts where they only have signatory authority, or investment and insurance products that do not look like ordinary bank accounts. Another recurring problem is relying on the old paper process. The IRS FBAR page is clear that the filing is electronic through FinCEN unless you receive a specific exemption from e-filing.
“The biggest FBAR risk is usually not the form itself,” says Kari Foss-Persson, Esq., Managing Partner at Vinland Immigration. “It is finding out too late that a small employer account or joint account should have been included from the start.”
If you missed prior years
The right cleanup path depends on why the filings were missed, how many years are open, and whether the failure was non-willful.
- 1
Rebuild the account history
Confirm each year in which your aggregate foreign-account value crossed the filing threshold.
- 2
Separate ownership from authority
List which accounts you owned and which accounts you merely controlled, because both can matter.
- 3
Choose the corrective path before filing
Late FBARs, amended tax returns, and any voluntary-compliance route should be coordinated rather than filed ad hoc.
- 4
Keep the explanations consistent
If you explain a late FBAR, make sure the same facts line up with Form 8938, Schedule B, and any amended returns.
