FBAR: reporting UK accounts to the US

Last checked

If your foreign accounts together top $10,000 at any point in the year, you file an FBAR. It reports the accounts; it does not tax them. Filing is free and online, and missing it carries real penalties.

The FBAR, the Foreign Bank Account Report, is filed on FinCEN Form 114. It is separate from your tax return and goes to the US Treasury, not the IRS. The rule is simple: add up the highest balance of every non-US account you hold or can control, and if the combined total crossed $10,000 at any single moment in the calendar year, you report all of them.

What counts toward the threshold

More than you might expect. Current accounts, savings accounts, ISAs, multi-currency wallets, investment accounts and most UK pensions count, as do accounts you do not own but can sign on, such as a business account. It is the aggregate that matters: five accounts of $3,000 each cross the line even though none does alone.

The threshold is a trigger, not a tax

Crossing $10,000 does not mean you owe anything. The FBAR is pure reporting. People conflate it with a charge and either panic or ignore it; both are wrong. You list the accounts, the highest balance in each, and the provider details, and you are done.

Deadline and penalties

The FBAR is due 15 April, with an automatic extension to 15 October, aligning with the US tax deadline. The penalties are where it gets serious: a non-willful failure can draw a penalty per year, and a willful one is far higher. The filing is straightforward; the cost of skipping it is not.

FBAR and Form 8938 are not the same

Both report foreign assets, but they are different forms with different thresholds and different recipients. Many people abroad file both. See Form 8938 for how the two differ.

Common questions

What is the FBAR threshold?

10,000 US dollars, aggregated across every account. Add up the highest balance of each non-US account you hold or can sign on, and if the combined total crossed 10,000 dollars at any single moment in the calendar year, you report all of them. Five accounts of 3,000 dollars each cross the line even though none does alone.

Does filing an FBAR mean I owe US tax?

No. The FBAR is pure reporting. You list the accounts, the highest balance in each and the provider details, and you are done. It is filed on FinCEN Form 114 and goes to the US Treasury separately from your tax return. Filing is free and online.

Which UK accounts count toward the FBAR?

More than most people expect. Current accounts, savings accounts, ISAs, multi-currency wallets, investment accounts and most UK pensions all count, as do accounts you do not own but can sign on, such as a business account.

When is the FBAR due?

15 April, with an automatic extension to 15 October, aligning with the US tax deadline. A non-willful failure to file can draw a penalty for each year and a willful one is far higher, so the cost of skipping it is much greater than the cost of filing.

Confirm your own position with a cross-border specialist. Acceptance policies and tax rules change, and your facts may differ from the general case. Rates and terms here are the provider's published figures rather than an offer, and the provider decides each application on its own criteria. Use this as a map, not a ruling. Last checked .
