FBAR Filing 2026: FinCEN Form 114 Rules & Penalties

The Foreign Bank Account Report (FBAR) — officially FinCEN Form 114 — is one of the most important compliance obligations for US citizens, green card holders and certain US residents with foreign financial accounts. Penalties for non-compliance can be severe, reaching $10,000 per violation for non-willful failures and up to the greater of $100,000 or 50% of the account balance for willful violations.

This 2026 guide covers who must file, what accounts trigger the requirement, deadlines, penalties, and how to catch up if you’re behind on filing.

What Is the FBAR?

The FBAR is a disclosure report filed with the Financial Crimes Enforcement Network (FinCEN) — a bureau of the US Treasury Department — not with the IRS. It is filed electronically through the BSA E-Filing System at bsaefiling.fincen.treas.gov.

The FBAR requirement stems from the Bank Secrecy Act (BSA), not the Internal Revenue Code, which means it operates entirely separately from your US tax return. Failing to file an FBAR is a civil and potentially criminal violation of the BSA — independent of whether you owe any US tax.

Who Must File an FBAR?

You must file an FBAR if all three of the following apply:

You are a US person (US citizen, US green card holder, US resident alien, or US-formed entity including corporations, partnerships, LLCs and trusts)
You have a financial interest in or signature authority over one or more foreign financial accounts
The aggregate maximum value of all such accounts exceeded $10,000 at any point during the calendar year

The $10,000 threshold applies to the aggregate of all foreign accounts combined — not per account. If you have five UK accounts each with £1,500, the total may trigger the filing requirement even though each account is below $10,000 individually.

What Accounts Must Be Reported?

The definition of a “foreign financial account” is broad. Reportable accounts include:

Bank accounts (current accounts, savings accounts, ISAs held at a bank)
Investment accounts held at foreign financial institutions
Mutual fund accounts
Foreign pension accounts (including UK workplace pensions and SIPPs — see below)
Accounts with foreign insurance companies with cash value
Commodity futures or options accounts
Accounts held in joint names (each account holder must separately file)

UK-Specific Accounts: ISAs, SIPPs, and Workplace Pensions

US expats in the UK frequently ask about specific UK financial vehicles:

ISAs (Individual Savings Accounts): ISAs held at a bank or financial institution must be reported on the FBAR. Note that ISAs held at UK investment platforms may also require FATCA reporting on Form 8938.
SIPPs (Self-Invested Personal Pensions): SIPPs are generally reportable on the FBAR. The value to report is typically the cash value of the account at its highest point during the year.
UK workplace pensions: Defined contribution occupational pensions and personal pension plans are reportable. Defined benefit (final salary) pension reporting is more complex — consult a specialist.
Premium Bonds: Premium Bonds held with NS&I are reportable as foreign financial accounts.

FBAR Deadlines 2026

Original deadline: April 15, 2026 (for the 2025 calendar year)
Automatic extension: October 15, 2026 — the extension is automatic; no action is required to receive it
The FBAR deadline is separate from the US tax return deadline. You can file your FBAR independently of your tax return.

FBAR Penalties: What’s at Stake

FBAR penalties are among the harshest in US tax law:

Non-Willful Violations

Up to $10,000 per violation per year. The US Supreme Court’s 2023 decision in Bittner v. United States held that the non-willful penalty applies per-form, not per-account — a significant taxpayer victory that limited penalty exposure for those who accidentally failed to file.

Willful Violations

The greater of $100,000 or 50% of the account balance per violation per year — potentially wiping out the entire value of an account. Criminal penalties including fines up to $250,000 and imprisonment up to 5 years are also possible for egregious cases.

How to File the FBAR

File electronically at bsaefiling.fincen.treas.gov
Use the FinCEN Form 114 (available through the BSA E-Filing System)
Report each account separately with institution name, address, account number, type, and maximum value during the year
Values must be converted to US dollars using the US Treasury Department’s exchange rate for December 31 of the tax year

FBAR vs. FATCA: What’s the Difference?

The FBAR and FATCA (Form 8938) are separate — but often overlapping — reporting requirements. Key differences:

FBAR: Filed with FinCEN (Treasury), BSA-based, applies from $10,000 aggregate threshold. Filed separately from your tax return.
FATCA/Form 8938: Filed with the IRS as part of your Form 1040, reporting threshold is higher ($200,000 for married filing jointly abroad at year-end), covers a broader range of “specified foreign financial assets” including foreign partnerships, corporations, and trusts.
Many accounts must be reported on both forms. Compliance with one does not satisfy the other.

Catching Up on Missed FBAR Filings

If you have not filed FBARs in previous years, there are IRS programmes to help you come into compliance without facing maximum penalties:

IRS Streamlined Filing Compliance Procedures

The most commonly used programme for expats. Under the Streamlined Foreign Offshore Procedure (SFOP), you file 3 years of amended/late tax returns and 6 years of FBARs and certify non-willfulness. The penalty for SFOP participants is zero (0%) — a complete amnesty for FBAR non-compliance for genuinely non-willful filers.

Read our detailed IRS Streamlined Filing Procedures 2026 guide for full eligibility requirements and the step-by-step process.

Delinquent FBAR Submission Procedures

If you have no unreported income but simply failed to file FBARs, the Delinquent FBAR Submission Procedures allow you to file the missing reports with a reasonable cause statement — potentially resulting in no penalty.

Frequently Asked Questions

Do I need to file an FBAR if I have no US tax liability?

Yes. FBAR filing is entirely separate from tax liability. Even if you owe no US taxes — for example, because the Foreign Tax Credit fully offsets your US tax bill — you must still file an FBAR if your foreign accounts exceeded $10,000.

Does my UK pension need to be reported on the FBAR?

In most cases, yes. Defined contribution pensions (personal pensions, SIPPs, and most workplace defined contribution schemes) are generally reportable. The treatment of defined benefit pensions is more complex. We recommend obtaining specialist advice, as incorrect reporting — or non-reporting — can have significant consequences.

What exchange rate should I use to value my accounts?

Use the US Treasury Fiscal Service exchange rates published for December 31 of the applicable calendar year. These rates are available at the US Treasury website. For GBP accounts, identify the December 31 GBP/USD rate and convert the maximum value of each account during the year.

I only had a joint account with my UK spouse — do I still need to file?

Yes, if the account exceeded $10,000 at any point during the year. As the US person, you must report your interest in the joint account. Your UK-citizen spouse does not have a US filing obligation (assuming they are not also a US person), but you must include the account on your FBAR.
