FBAR Filing Guide: Everything Americans Abroad Need to Know

What Is the FBAR?

The FBAR, officially known as FinCEN Form 114 (Report of Foreign Bank and Financial Accounts), is a reporting requirement administered by the Financial Crimes Enforcement Network (FinCEN), a bureau of the US Department of the Treasury. Despite being closely associated with tax filing, the FBAR is not a tax form and is not filed with the IRS. It exists under the Bank Secrecy Act (BSA) as part of the US government's efforts to combat money laundering, tax evasion, and other financial crimes.

For Americans living abroad, the FBAR is one of the most important compliance obligations you will encounter. It is also one of the most frequently overlooked, and the penalties for failing to file are among the most severe in the entire US regulatory framework. Understanding who must file, what to report, and how to do it correctly is essential.

Who Must File an FBAR

The filing requirement applies to any United States person who has a financial interest in or signature authority over one or more foreign financial accounts, if the aggregate value of all such accounts exceeds $10,000 at any point during the calendar year.

A "United States person" includes:

• US citizens (including those living abroad)
• US permanent residents (green card holders)
• US residents under the substantial presence test
• Domestic entities such as corporations, partnerships, LLCs, trusts, and estates formed under US law

The $10,000 Threshold

The $10,000 threshold is an aggregate figure, not a per-account threshold. This is a critical distinction. If you have three foreign accounts with maximum balances of $4,000, $3,500, and $3,000 during the year, the aggregate is $10,500 and you must file an FBAR even though no single account exceeded $10,000.

The threshold is based on the maximum value of the account at any point during the calendar year, not the year-end balance. If your account held $11,000 on March 15 but only $2,000 on December 31, you still must file because the account exceeded the threshold during the year.

Signature Authority

Even if you do not own the funds in a foreign account, you may still have a filing obligation. Signature authority means you have the ability to control the disposition of money, funds, or other assets in the account by direct communication with the financial institution. This commonly applies to business owners, corporate officers, and employees who can sign on company accounts.

What Accounts Must Be Reported

The FBAR requires reporting of "foreign financial accounts." This term is broadly defined and includes more than just bank accounts.

Accounts That Must Be Reported

• Bank accounts: Savings accounts, checking accounts, and time deposits (CDs) held at foreign banks
• Securities accounts: Brokerage accounts, custodial accounts, and securities held with foreign financial institutions
• Mutual funds and pooled funds: Shares in foreign mutual funds and similar pooled investment vehicles
• Insurance policies with cash value: Certain foreign insurance policies that have accumulated a cash surrender value
• Pension and retirement accounts: Foreign pension plans, retirement savings accounts, and provident funds
• Accounts held through foreign payment services: If a foreign entity holds funds on your behalf (certain foreign digital wallets may qualify)
• Accounts in which you have signature authority: Even if you are not the owner

Accounts That Generally Do Not Need to Be Reported

• Accounts at US military banking facilities
• Correspondent and nostro accounts (these are bank-to-bank accounts)
• Accounts owned by a governmental entity
• Accounts held at an international financial institution of which the US is a member (such as the World Bank or IMF)

What Is a "Foreign" Account?

An account is "foreign" if it is maintained with a financial institution located outside of the United States. The citizenship or nationality of the account holder does not matter. An account at a US bank's branch in London is a foreign account. An account at a foreign bank's branch in New York is not.

How to File the FBAR

The FBAR must be filed electronically through FinCEN's BSA E-Filing System at bsaefiling.fincen.treas.gov. There is no paper filing option for individuals. Here is the step-by-step process.

Step 1: Gather Your Account Information

For each foreign financial account that must be reported, you will need:

• Name of the financial institution
• Account number
• Type of account (bank, securities, etc.)
• Maximum value of the account during the calendar year
• Currency of the account
• Address of the financial institution
• Country where the account is maintained

Step 2: Determine Maximum Account Values

For each account, determine the highest balance at any point during the calendar year. Convert foreign currency amounts to US dollars using the Treasury Department's end-of-year exchange rate for the applicable year. The Treasury publishes these rates at fiscaldata.treasury.gov.

Note that you use the end-of-year exchange rate for all accounts, regardless of when the maximum balance occurred. This is different from how you convert income on your tax return.

Step 3: File Electronically

Visit the BSA E-Filing System and select "File FBAR (FinCEN Report 114)." You can file as an individual or authorize a third party (such as a tax preparer) to file on your behalf. The form is completed online and submitted electronically.

You do not need to attach any supporting documents, such as bank statements, when filing. However, you should retain records of your account balances, statements, and other relevant documentation for at least five years from the FBAR due date, in case FinCEN or the IRS requests them.

Step 4: Save Your Confirmation

After submission, you will receive a confirmation number and a tracking ID. Save these. They serve as your proof of timely filing.

FBAR Deadlines

The FBAR for the calendar year is due on April 15 of the following year. However, unlike the tax return, there is an automatic extension to October 15 with no action required on your part. You do not need to file any form to get this extension; it is applied automatically.

For tax year 2025:

• April 15, 2026: Original due date
• October 15, 2026: Automatic extended due date

There is no further extension available beyond October 15.

FBAR vs. Tax Return Deadlines

It is important not to confuse the FBAR deadline with your tax return deadline. While both are initially due on April 15, the extension mechanisms are different. Your tax return extension (Form 4868) does not extend your FBAR deadline, and the FBAR's automatic extension to October 15 does not extend your tax return.

Penalties for Non-Compliance

FBAR penalties are notoriously severe and can be financially devastating. The penalty structure distinguishes between non-willful and willful violations.

Non-Willful Violations

If the IRS determines that your failure to file was not willful (meaning it was due to negligence, mistake, or ignorance rather than intentional disregard), the penalty can be up to $16,117 per violation for 2025. Each unreported account in each year can constitute a separate violation, meaning penalties can accumulate rapidly.

Willful Violations

If the failure to file is determined to be willful, penalties increase dramatically. The penalty for a willful violation is the greater of $161,170 or 50% of the balance in the account at the time of the violation. This means that for a single account with $500,000, the willful penalty could be $250,000, and this applies per account, per year.

Criminal Penalties

In extreme cases, willful failure to file an FBAR can result in criminal prosecution. Criminal penalties include fines of up to $500,000 and imprisonment of up to 10 years, or both.

Reasonable Cause Exception

FinCEN may waive penalties if you can demonstrate reasonable cause for the failure to file. Reasonable cause requires showing that you exercised ordinary business care and prudence but were still unable to meet the filing requirement. Simply being unaware of the requirement is generally not considered reasonable cause on its own, though it may be a factor.

Common Mistakes When Filing the FBAR

Mistake 1: Assuming the $10,000 Threshold Is Per Account

As noted earlier, the $10,000 threshold is aggregate across all foreign accounts. We frequently see clients who assumed they did not need to file because no single account exceeded $10,000, even though their combined balances did.

Mistake 2: Forgetting Joint Accounts

If you have a joint account with your spouse or anyone else, the full value of the account is reportable by each person with a financial interest. A joint account with a $15,000 balance must be reported by both account holders on their individual FBARs.

Mistake 3: Not Reporting Accounts With Zero Balances

If you had a foreign account that was open at any point during the year and your aggregate balance across all accounts exceeded $10,000 at any point, you must report all accounts, including those with zero or minimal balances at year-end.

Mistake 4: Using the Wrong Exchange Rate

FBAR account values must be converted to US dollars using the Treasury Department's end-of-year exchange rate. Using the rate from the date of the maximum balance, or an average rate, is incorrect.

Mistake 5: Not Filing Because You Already Filed Form 8938

The FBAR and FATCA (Form 8938) are separate requirements. Filing one does not satisfy the other. Many accounts must be reported on both. Failing to file either one carries its own set of penalties.

Mistake 6: Overlooking Signature Authority Accounts

If you have signature authority over a business account, a family member's account, or any other foreign account, it is reportable even though the funds are not yours. This catches many business owners and corporate executives off guard.

What to Do If You Are Behind on FBAR Filings

If you have not filed FBARs for prior years, do not panic, but do act. The IRS offers several paths to come into compliance.

Streamlined Filing Compliance Procedures

If your failure to file was non-willful, the Streamlined Filing Compliance Procedures allow you to file the last 6 years of delinquent FBARs (along with 3 years of tax returns) without facing penalties. You must certify under penalties of perjury that the failure was not willful. For qualifying expats using the Streamlined Foreign Offshore Procedures, there is no miscellaneous offshore penalty.

Delinquent FBAR Submission Procedures

If you have no unreported income and are not under examination by the IRS, you may be able to file late FBARs through the Delinquent FBAR Submission Procedures. You file the late FBARs electronically and include a statement explaining why they are late. The IRS has stated it will not impose penalties if you properly reported all income and paid all tax.

Voluntary Disclosure Practice

If your failure to file was willful, the Voluntary Disclosure Practice may be the best option to avoid criminal prosecution, though it typically involves substantial penalties.

FBAR vs. FATCA (Form 8938): Understanding the Difference

These two reporting requirements confuse many expats because they overlap significantly. Here is a quick comparison:

Both must be filed if you meet both thresholds. Filing one does not replace the other.
