FBAR: Foreign Bank Account Reporting (FinCEN Form 114)

The FBAR; formally FinCEN Form 114, Report of Foreign Bank and Financial Accounts; is a mandatory disclosure form for any U.S. person with foreign financial accounts exceeding $10,000 in aggregate value at any point during the calendar year. Unlike most tax forms, the FBAR is filed with the Financial Crimes Enforcement Network (FinCEN), not the IRS, and the penalties for non-compliance are among the most severe in all of U.S. financial reporting; up to $161,170 per willful violation per account per year.

History and Origin

The FBAR requirement dates back to the Bank Secrecy Act (BSA) of 1970, one of the earliest pieces of U.S. legislation aimed at combating money laundering, tax evasion, and other financial crimes. The BSA authorized the Treasury Department to require financial institutions and individuals to keep records and file reports that would be useful in criminal, tax, and regulatory investigations.

For decades, the FBAR was a little-known requirement that was rarely enforced. The reporting threshold of $10,000; set in 1970 — has never been adjusted for inflation. That $10,000 would be worth over $80,000 in 2025 dollars, which gives some perspective on how many more people the requirement now captures.

Enforcement shifted materially after September 11, 2001. The USA PATRIOT Act of 2001 expanded the BSA's scope and gave regulators new tools to detect terrorist financing and money laundering. In 2003, the Treasury Department delegated FBAR enforcement authority to the IRS, which had the resources and expertise to pursue individual taxpayers.

The UBS scandal of 2008-2009 was a turning point. When Swiss bank UBS admitted to helping over 19,000 American clients hide assets from the IRS, the government launched the Offshore Voluntary Disclosure Program (OVDP) and aggressively pursued FBAR penalties. Suddenly, a form that most Americans had never heard of became front-page news. The OVDP collected billions of dollars in back taxes, penalties, and interest, and the IRS made clear that FBAR enforcement was a permanent priority.

Who Files It and When

A U.S. person must file an FBAR if they have a financial interest in or signature authority over one or more foreign financial accounts, and the aggregate value of all foreign accounts exceeds $10,000 at any time during the calendar year. "U.S. person" includes:

• U.S. citizens (including those living abroad)
• U.S. residents (green card holders and those meeting the substantial presence test)
• Domestic entities; corporations, partnerships, LLCs, trusts, and estates formed in the U.S.

"Foreign financial account" includes:

• Bank accounts (checking, savings, time deposits)
• Securities accounts (brokerage accounts held at foreign institutions)
• Commodity futures or options accounts
• Insurance policies with cash value (held by a foreign institution)
• Mutual funds and similar pooled investment vehicles

The FBAR is due April 15, with an automatic extension to October 15. No separate extension form is needed; the extension is automatic. The form must be filed electronically through the FinCEN BSA E-Filing System.

A critical nuance: the $10,000 threshold is based on aggregate value across all accounts. If you have three foreign accounts with balances of $4,000, $3,500, and $3,000, none individually exceeds $10,000, but their combined $10,500 triggers the filing requirement.

Key Sections Explained

Filer Information

The form begins with identification information — name, SSN/ITIN, date of birth, and address. If you are filing jointly with a spouse, both names and SSNs are required.

Account Information

For each foreign account, you must report:

• The name of the foreign financial institution
• The account number
• The country where the account is located
• The type of account (bank, securities, or other)
• The maximum value of the account during the calendar year, converted to U.S. dollars using the Treasury's year-end exchange rate
• Whether you have a financial interest or signature authority (or both)

Financial Interest vs. Signature Authority

A financial interest exists if you own the account, or if you own more than 50% of an entity that owns the account. Signature authority means you can control the disposition of assets in the account by direct communication with the financial institution, even if you do not own the account — for example, corporate officers who can sign on a company's foreign bank account.

Joint Accounts

If you jointly own a foreign account with your spouse, you can file a joint FBAR if all accounts are jointly owned. If any account is held by only one spouse, separate FBARs must be filed.

Common Mistakes

• Not knowing about the FBAR requirement. This is the most common issue. Many Americans with foreign accounts — particularly expatriates, immigrants, and dual citizens — are genuinely unaware that the FBAR exists. Ignorance is not a defense against penalties, but it may reduce them from "willful" to "non-willful" levels.
• Confusing the FBAR with Form 8938. The FBAR is filed with FinCEN; Form 8938 is filed with the IRS as part of your tax return. They have different thresholds, different reporting requirements, and different penalties. Many taxpayers with foreign accounts must file both.
• Using the wrong exchange rate. The FBAR requires the Treasury's year-end exchange rate for converting foreign currency to U.S. dollars. Using the exchange rate from the date of maximum value, or any other rate, is incorrect.
• Forgetting about foreign retirement accounts. Some foreign pension plans and retirement accounts may be reportable on the FBAR. The rules are complex and depend on the specific type of account and the country's tax treaty with the U.S.
• Not reporting accounts with signature authority only. Even if you do not own the account, having signature authority (such as being an authorized signer on a parent's foreign account) may trigger a filing requirement.
• Missing the aggregate threshold. Each account may be well under $10,000, but if the combined total of all foreign accounts exceeds $10,000 at any point during the year, you must report all of them — not just those over $10,000.

Recent Changes

Penalties for FBAR violations have been adjusted for inflation annually. For 2024, the maximum penalty for a willful violation is $161,170 per account per year. Non-willful penalties can reach $16,117 per violation. The IRS has been aggressive in asserting willfulness, and several federal court cases have upheld penalties that exceeded the total value of the unreported accounts.

The IRS's offshore enforcement programs have evolved over time. The Offshore Voluntary Disclosure Program (OVDP) was closed in 2018, replaced by the Streamlined Filing Compliance Procedures, which offer reduced penalties for taxpayers who can certify that their failure to file was non-willful. The streamlined domestic program carries a 5% penalty on the highest aggregate balance; the streamlined foreign program may waive penalties entirely for eligible taxpayers living abroad.

Cryptocurrency held on foreign exchanges presents emerging questions for FBAR compliance. FinCEN has indicated that foreign crypto exchange accounts may be reportable, but formal guidance has been limited. Taxpayers holding significant crypto on foreign platforms should consult a tax professional about their FBAR obligations.
