FinCEN 114

FinCEN, Report of Foreign Bank and Financial Accounts (FBAR)

The annual report of foreign accounts filed with FinCEN, separate from the tax return, once combined balances pass the threshold.

What is FinCEN 114?

The FBAR is filed by US persons whose foreign accounts together exceed the reporting threshold at any point in the year. It goes to the Financial Crimes Enforcement Network, not the IRS, and it is not part of the tax return. For Americans in the UK, it usually covers current accounts, savings accounts, ISAs and investment platforms.

Reporting UK accounts to the Treasury

The threshold is an aggregate. If the highest balances of all foreign accounts, added together, exceed $10,000 at any time in the year, every account is reported, including small ones.

The maximum value of each account is converted to dollars at the Treasury year-end rate. The report is filed electronically through the BSA E-Filing System and is due 15 April, extended automatically to 15 October, with no request needed for the later date.

Ownership is not the only trigger. Signature authority over an account also counts, which catches employees who can move money in an employer's account, parents named on a child's account, and people holding a power of attorney for an elderly relative. Joint accounts with a non-US spouse are reported in full by the US spouse. Accounts held through an entity may be reportable where the filer owns more than half of it.

Penalties are the reason the FBAR draws attention. The non-wilful penalty applies per report rather than per account, following the Supreme Court's 2023 decision in Bittner v. United States. Wilful failures carry much heavier penalties. Records of each account must be kept for five years. People who have missed years usually look at the Streamlined procedures or the delinquent FBAR submission procedures, depending on whether income was also left off their returns.

How we handle it

  • Foreign Income & FBAR

    FBAR and Form 8938 reporting for UK accounts, with the income those accounts produce reported correctly on the US return.

  • IRS Streamlined Filing

    Catch-up filing under the IRS Streamlined Filing Compliance Procedures for people whose missed US returns and FBARs were non-wilful.

  • Individual Tax Returns

    US federal returns for Americans living in the UK and British nationals with US income, prepared with the UK figures in view.

  • Cross-Border Tax

    US and UK returns prepared together from one set of workpapers, so credits, tax years and exchange rates line up across both.

Questions we are asked

Big Ben and the Houses of Parliament
I have several small accounts, none near the threshold. Do I file?

Possibly. The test adds the maximum values of all foreign accounts together. If that combined figure exceeds $10,000 at any time in the year, every account must be reported, even ones with very small balances. An ISA, a current account and a savings account can pass the threshold together without any one of them coming close.

Is the FBAR the same as Form 8938?

No. They overlap but are separate. The FBAR goes to FinCEN on its own, has a lower threshold and includes signature authority. Form 8938 is attached to the tax return, has higher thresholds for people living abroad and covers some assets the FBAR does not, such as directly held foreign shares. Many UK residents file both, reporting the same accounts twice.

I have never filed an FBAR. What should I do?

The route depends on whether all income was reported on tax returns. Where it was, the delinquent FBAR submission procedures may apply. Where income was also omitted, the Streamlined procedures are usually considered, with a certification of non-wilful conduct. Neither is available once the IRS has opened an examination. The facts of each year determine which fits.
