FBAR for US Expats in Europe: What You Need to Know Before 15 October

Most Americans living in Europe first hear about FBAR from a bank — or from a tax preparer who mentions it almost in passing. If that sounds familiar, you are not alone. FBAR is one of the most widely misunderstood compliance obligations for US expats, and the 15 October deadline catches people by surprise every year.

Here is what you need to know.

What is FBAR?

FBAR stands for Report of Foreign Bank and Financial Accounts. It is filed with the Financial Crimes Enforcement Network (FinCEN), not with the IRS, and it is separate from your US tax return. The purpose is straightforward: the US government requires citizens and residents to report foreign financial accounts that meet the filing threshold, so it has visibility of assets held outside the United States.

Who needs to file?

You must file an FBAR if you are a US person — a US citizen, a Green Card holder, or a US tax resident — and the aggregate value of your foreign financial accounts exceeded $10,000 at any point during the calendar year.

That $10,000 threshold is cumulative across all your foreign accounts, not per account. If you have three accounts in Ireland, Germany and Spain that each held $4,000 at their peak, you still have a filing requirement.

What counts as a reportable account?

A reportable account is any financial account held at a foreign financial institution in which you have a financial interest or signature authority. This includes:

• Bank accounts (current, savings, deposit)

• Brokerage and investment accounts

• Pension and retirement accounts held outside the US

• Certain life insurance policies with a cash value

If you are unsure whether a specific account or structure is reportable, that question is worth discussing with a qualified adviser before the deadline.

What is the deadline?

The standard FBAR deadline is 15 April, aligned with the US tax filing deadline. However, an automatic extension to 15 October is available to all filers. For 2026, that means the extended deadline is 15 October 2026.

There is nothing to file to claim the extension — it is automatic. But 15 October is a hard deadline. There is no further extension.

What happens if you miss it?

The penalties for a missed or inaccurate FBAR are significant.

For a non-wilful violation — meaning you genuinely were not aware of the requirement — the penalty can reach up to $10,000 per violation. For wilful non-compliance, penalties are substantially higher and can include criminal exposure.

That said, FinCEN and the IRS operate voluntary disclosure programmes for expats who have never filed but come forward proactively. If you have missed prior years, the situation is almost always more manageable when addressed before you are contacted by authorities rather than after.
