What Is an FBAR? Understanding FinCEN Form 114

What the FBAR Is

FBAR stands for Report of Foreign Bank and Financial Accounts. It is filed on FinCEN Form 114, an electronic disclosure that certain U.S. persons must submit each year if they have a financial interest in, or signature authority over, foreign financial accounts whose combined value exceeded $10,000 at any point during the calendar year.

Despite the acronym's resemblance to a tax form, the FBAR is not a tax return. It doesn't calculate income, deductions, or tax owed. It is purely an information report — a snapshot of foreign accounts designed to give the U.S. government visibility into money held outside the country.

Why the FBAR Exists

The filing requirement traces back to the Bank Secrecy Act of 1970, a law passed to help law enforcement detect money laundering, tax evasion, and other financial crimes by requiring reporting on transactions and account holdings that might otherwise stay invisible to U.S. regulators. Foreign accounts have historically been harder for the government to see than domestic ones, so Congress built a reporting mechanism aimed specifically at them.

For decades the requirement existed quietly, with limited enforcement. That changed substantially in the years following 2001, as combating money laundering and offshore tax evasion became a higher enforcement priority — a shift we cover in more depth in our history of the FBAR.

FinCEN vs. the IRS: Who Actually Collects This Form

The FBAR is filed with the Financial Crimes Enforcement Network (FinCEN), a bureau of the U.S. Department of the Treasury — not directly with the IRS, and not attached to your Form 1040. That said, the IRS has been delegated authority to enforce FBAR compliance and examine filers, which is why FBAR questions often come up during a tax audit even though the form itself lives in a separate system.

Do You Need to File One?

At a high level, you may need to file if all of the following are true:

• You are a "U.S. person" — a category broader than just citizens (see our full breakdown of who qualifies).
• You had a financial interest in, or signature authority over, one or more accounts located outside the United States.
• The combined value of those accounts exceeded $10,000 at any moment during the calendar year — even if only briefly, and even if the balance later dropped back down.

Qualifying accounts typically include foreign bank accounts, brokerage and securities accounts, mutual funds, and certain pension or insurance accounts with a cash value. Real estate held directly (not through a foreign account) generally does not count on its own.

How the FBAR Is Actually Filed

The FBAR is filed entirely online through FinCEN's BSA E-Filing System. Paper filing is no longer accepted for most filers. There is no fee to file. For each qualifying account, you'll typically need:

1. The name and address of the financial institution.
2. The account number or other identifier.
3. The type of account (bank, securities, or other).
4. The maximum value the account reached during the calendar year, converted to U.S. dollars.

Not the Same as FATCA's Form 8938

A common point of confusion: the FBAR is frequently mixed up with Form 8938, the FATCA-driven disclosure filed with the IRS as part of your tax return. They cover overlapping — but not identical — territory, have different thresholds, and in many cases you'll need to file both. We cover the distinction in detail in FBAR vs. Form 8938.
