FBAR Filing: What US Persons With Foreign Accounts Must Know

If you have a bank account, investment account, or other financial account outside the United States, you may be required to file a Report of Foreign Bank and Financial Accounts — commonly known as the FBAR. Missing this filing can result in severe penalties, even if you owe no additional tax and even if the accounts were fully disclosed on your tax return. Here is what you need to know — and what the IRS and FinCEN actually look for.

The FBAR is filed with the Financial Crimes Enforcement Network (FinCEN), not the IRS. It is submitted electronically through the BSA E-Filing System using FinCEN Form 114. Despite being a separate filing from your tax return, it is closely tied to your overall US tax compliance picture — and the IRS has access to FBAR data.

The FBAR is rooted in the Bank Secrecy Act of 1970, a law designed to combat money laundering, tax evasion, and other financial crimes. The US government uses FBAR data to track offshore financial activity by US persons and to identify accounts that may be generating unreported income.

The FBAR is not a tax form. You do not pay tax on the FBAR itself. But failing to file it — even when all income from the accounts was properly reported on your 1040 — can result in penalties that dwarf the tax liability on the underlying income.

You must file an FBAR if you are a US person and you meet the aggregate threshold. "US person" is defined broadly under 31 CFR § 1010.350 to include:

• US citizens — regardless of where they live
• Green card holders — regardless of where they live
• Resident aliens — those who meet the substantial presence test under IRC § 7701(b)
• Domestic entities — US-formed LLCs, corporations, partnerships, and trusts that have a financial interest in or signature authority over foreign accounts

The threshold is:

This is not a year-end balance test. If your foreign accounts collectively reached $10,001 on a single day in March and dropped back to zero by December 31, you still have a filing obligation for that year. The IRS has successfully argued this point in numerous cases.

The $10,000 threshold applies to the combined maximum value of all foreign accounts, not each account individually. If you have three foreign accounts — one with a peak balance of $4,000, one with $3,500, and one with $3,000 — the aggregate peak is $10,500, and you must file even though no single account exceeded $10,000.

For accounts denominated in foreign currency, you convert to US dollars using the Treasury's year-end exchange rate for the relevant year, published annually on the FinCEN website.

The FBAR covers a broad range of foreign financial accounts. The key question is whether the account is a "financial account" at a "financial institution" located outside the United States. Reportable accounts include:

• Bank accounts — checking, savings, time deposits, certificates of deposit
• Investment and brokerage accounts — stocks, bonds, mutual funds held at a foreign institution
• Foreign mutual funds — funds organized outside the US, even if traded on a US exchange
• Foreign pension and retirement accounts — in many cases, though treaty analysis may affect reporting obligations
• Life insurance policies with a cash surrender value — whole life, universal life, and similar products held at a foreign insurer
• Accounts held jointly with a non-US person — you report your interest in the account
• Accounts over which you have signature authority — even if you have no financial interest (see below)

• Foreign real estate held directly — a vacation home or rental property in another country is not a financial account. However, rental income and capital gains are still taxable on your US return, and if the property is held through a foreign entity, that entity's accounts may be reportable.
• Precious metals held directly — physical gold or silver held outside the US is not a financial account
• Foreign currency held directly — cash in a foreign currency not held in an account
• US military banking facilities — accounts at US military banking facilities operated by a US financial institution

The FBAR is due April 15, with an automatic extension to October 15 — no extension request is required. This aligns with the individual tax return calendar, making it easier to coordinate both filings. If you file your tax return on extension, your FBAR is automatically extended to October 15 as well.

The FBAR is filed electronically through the BSA E-Filing System at bsaefiling.fincen.treas.gov. It cannot be filed on paper. There is no filing fee.

This is where FBAR becomes serious. The penalties for failing to file are among the harshest in the US tax code — and they apply per account, per year.

A non-willful violation is one where the failure to file was due to negligence, inadvertence, or mistake — not intentional disregard of the law. The penalty is up to $10,000 per violation (adjusted for inflation; currently approximately $16,117 for 2025).

The IRS has taken the position that each account in each year is a separate violation. If you had three unreported foreign accounts for five years, that is potentially 15 separate violations — up to $241,755 in penalties — even if you owed no additional tax.

The Supreme Court addressed the per-violation question in Bittner v. United States (2023), holding that the non-willful penalty applies per report (i.e., per year), not per account. This was a significant taxpayer victory that limits non-willful penalties to $10,000–$16,000 per year of non-filing, regardless of how many accounts were unreported.

A willful violation is one where the taxpayer knew about the FBAR requirement and intentionally failed to comply. The penalty is the greater of $100,000 or 50% of the account balance per violation — and courts have generally held that each account in each year is a separate willful violation.

The consequences of a willful determination are severe. A taxpayer with $500,000 in an unreported foreign account for three years could face penalties of $750,000 (50% × $500,000 × 3 years) — exceeding the account balance itself.

Willfulness does not require proof of intent to evade taxes. Courts have found willfulness where taxpayers:

• Signed tax returns that asked about foreign accounts and answered "no" — even without reading the question carefully (United States v. Williams, 4th Cir. 2012)
• Were sophisticated investors or business people who "recklessly disregarded" their obligations
• Received advice from a foreign bank to keep accounts secret
• Transferred funds to avoid detection

The "reckless disregard" standard is a lower bar than intentional evasion. If you knew you had foreign accounts, knew you had US tax obligations, and did not investigate whether you had an FBAR obligation, a court may find willfulness.

In egregious cases — particularly those involving large balances, deliberate concealment, or foreign bank assistance — the Department of Justice can pursue criminal charges under 31 USC § 5322. Criminal penalties include fines up to $500,000 and imprisonment up to 10 years. Criminal FBAR prosecutions are relatively rare but real, particularly for taxpayers with accounts at banks that have entered into deferred prosecution agreements with the DOJ (UBS, Credit Suisse, and dozens of others).

You may have an FBAR obligation even if you do not own the account. Signature authority — the legal authority to control the disposition of assets in an account by direct communication with the financial institution — can trigger a filing requirement.

This is particularly relevant for:

• Corporate officers and directors of companies with foreign subsidiaries or accounts
• Employees who are authorized signatories on company foreign accounts
• Trustees of trusts with foreign accounts
• Power of attorney holders with authority over foreign accounts

If you are an executive at a company with overseas operations, check with your tax advisor about whether you have a personal FBAR obligation. The company's FBAR filing does not relieve you of your individual obligation if you have signature authority.

FinCEN has provided relief for certain employees and officers of publicly traded companies and their subsidiaries, but the relief is conditional and requires careful analysis.

Many people confuse the FBAR with FATCA (Foreign Account Tax Compliance Act), which requires filing Form 8938 with your tax return. Both involve foreign financial accounts, but they are separate requirements with different thresholds, different filing destinations, and different legal authority.

You may be required to file both. Meeting the FBAR threshold does not exempt you from FATCA, and vice versa. The accounts reported on each form may overlap, but the forms serve different legal purposes and go to different agencies.

Foreign pension and retirement accounts are among the most frequently misunderstood FBAR reporting obligations. The general rule is that a foreign pension account is reportable if it is a financial account at a foreign financial institution.

However, tax treaty analysis can affect the reporting and taxation of foreign pension income. The US has tax treaties with many countries — including the UK, Canada, Germany, Australia, and Japan — that provide specific treatment for pension income. Some treaties exempt foreign pension contributions from US taxation; others provide for reduced withholding on distributions.

The treaty analysis does not eliminate the FBAR filing obligation, but it can affect the income tax consequences. If you have a foreign pension — a UK SIPP, a Canadian RRSP, an Australian superannuation fund — get specific advice before assuming the account is either reportable or exempt.

If you have unreported foreign accounts from prior years, the IRS offers Streamlined Filing Compliance Procedures for taxpayers who were non-willful in their non-compliance. This program allows you to file amended returns and delinquent FBARs with significantly reduced penalties.

For US residents who were non-willful:

• File amended returns for the three most recent tax years
• File delinquent FBARs for the six most recent years
• Pay a 5% miscellaneous offshore penalty on the highest aggregate balance of unreported foreign accounts during the covered period
• Certify under penalty of perjury that the failure was non-willful

For US persons living abroad who were non-willful:

• Same amended return and FBAR filing requirements
• No miscellaneous offshore penalty — the program is penalty-free for qualifying taxpayers
• Must meet the non-residency requirement (generally, not having a US abode and being physically outside the US for at least 330 days in one of the three covered years)

If you have no unreported income — the accounts were properly reported on your tax returns, you just forgot to file the FBAR — you may be able to file delinquent FBARs without penalty under the Delinquent FBAR Submission Procedures. You file the late FBARs with an explanation, and the IRS generally does not impose penalties if there is no unreported income.

The Streamlined Procedures are only available to taxpayers who are not already under IRS examination. Once the IRS opens an examination of your returns or your FBAR compliance, the voluntary disclosure window closes. Acting proactively — before the IRS finds the accounts — is always better than waiting.

The IRS has obtained account information from dozens of foreign banks through deferred prosecution agreements, John Doe summonses, and FATCA reporting. If your bank has entered into a compliance agreement with the DOJ, there is a real possibility that your account information has already been shared with US authorities.

Mistake 1: Assuming the $10,000 threshold is a year-end test. It is not. The threshold is the aggregate maximum value at any point during the year. Track peak balances, not December 31 balances.

Mistake 2: Forgetting accounts you have signature authority over. Corporate officers routinely overlook their personal FBAR obligation for company accounts. Review your signature authority at the start of each year.

Mistake 3: Assuming a foreign pension is not reportable. Most foreign pension accounts are reportable. Get specific advice before concluding otherwise.

Mistake 4: Conflating FBAR and FATCA. They are separate requirements. Filing Form 8938 does not satisfy your FBAR obligation, and vice versa.

Mistake 5: Waiting to see if the IRS finds the accounts. The IRS has more information about foreign accounts than most taxpayers realize. The Streamlined Procedures are a far better outcome than an IRS-initiated examination.

FBAR compliance intersects with international tax law, treaty analysis, penalty abatement procedures, and — in some cases — criminal defense. It is not an area where guesswork is acceptable, and the cost of getting it wrong can be catastrophic.
