FBAR and FATCA: Foreign Account Reporting Requirements Explained

If you have financial accounts outside the United States, you may have two separate reporting obligations: the FBAR (filed with the Treasury Department) and FATCA Form 8938 (filed with the IRS). Missing either one can result in significant penalties, even if you owe no additional tax. This guide explains who must file, what the thresholds are, and how to stay compliant.

Key Takeaways

• FBAR is required when foreign accounts exceed $10,000 in aggregate at any point during the year.
• FATCA (Form 8938) has higher thresholds and is filed with your tax return.
• Many people must file both FBAR and Form 8938 -- they are not substitutes for each other.
• Penalties for non-filing are severe, even for non-willful violations.

FBAR: Report of Foreign Bank and Financial Accounts

What Is the FBAR?

The FBAR (Foreign Bank Account Report) is filed on FinCEN Form 114 with the Financial Crimes Enforcement Network (FinCEN), a bureau of the U.S. Treasury Department. It is not filed with the IRS or attached to your tax return.

The FBAR originated under the Bank Secrecy Act (BSA) and is primarily an anti-money-laundering tool, but it applies broadly to anyone with foreign financial accounts.

Who Must File

You must file an FBAR if:

1. You are a U.S. person (citizen, resident alien, or entity formed under U.S. law)
2. You had a financial interest in or signature authority over at least one foreign financial account
3. The aggregate value of all foreign accounts exceeded $10,000 at any time during the calendar year

Aggregate means combined. If you have three accounts with maximum balances of $4,000, $3,500, and $3,000, their aggregate ($10,500) exceeds the threshold, so all three must be reported.

What Accounts Must Be Reported

Bank accounts (checking, savings)	Yes
Securities accounts (brokerage)	Yes
Mutual funds and pooled investments	Yes

FBAR Penalties

FBAR penalties are among the harshest in tax law — significantly steeper than typical IRS penalties and interest:

Violation Type	Maximum Penalty
Non-willful	Up to $16,117 per account per year (2025)
Willful	Greater of $161,171 or 50% of account balance per year
Criminal (willful)	Up to $500,000 fine and/or 10 years imprisonment

The IRS has discretion to assess penalties per account per year, meaning multiple accounts over multiple years can create staggering liability.

FATCA: Foreign Account Tax Compliance Act (Form 8938)

What Is FATCA?

FATCA was enacted in 2010 to combat offshore tax evasion. It has two components:

1. For individuals: Reporting foreign financial assets on Form 8938 with your tax return
2. For foreign financial institutions: Reporting U.S. account holders to the IRS (this happens automatically and is why your foreign bank asks about your U.S. status)

Filing Thresholds

FATCA thresholds are significantly higher than the FBAR and depend on filing status and residency:

You must file if your foreign assets exceed either the end-of-year threshold or the any-time-during-year threshold.

What Assets Must Be Reported

Form 8938 covers a broader range of assets than FBAR:

Asset Type	Form 8938?	FBAR?
Foreign bank accounts	Yes	Yes
Foreign brokerage accounts	Yes	Yes
Foreign stocks/securities (held directly, not in a U.S. account)	Yes	No
Foreign partnership interests	Yes	No
Foreign mutual funds (PFICs)	Yes	Yes
Foreign hedge funds	Yes	Yes
Foreign pension/retirement accounts	Yes	Yes
Foreign life insurance/annuities	Yes	Yes
Foreign real estate held directly	No	No
Foreign real estate held through entity	Yes (the entity interest)	No

Filing Details

Item	Requirement
Form	IRS Form 8938
Filed with	IRS (attached to Form 1040)
Deadline	Tax return due date (including extensions)
Filing method	Paper or electronic with tax return
Cost	Free (or included in tax prep fees)

FATCA Penalties

Violation	Penalty
Failure to file	$10,000 per year
Continued failure after IRS notice	Additional $10,000 for each 30-day period (up to $60,000)
Underpayment due to undisclosed assets	40% penalty on the underpayment (vs normal 20%)
Fraud	75% civil fraud penalty

FBAR vs FATCA: Side-by-Side Comparison

Feature	FBAR (FinCEN 114)	FATCA (Form 8938)
Authority	Bank Secrecy Act / Treasury	IRC / IRS
Threshold	$10,000 aggregate	$50,000-$600,000 (varies)
Filed with	FinCEN (BSA E-Filing)	IRS (with tax return)
Deadline	April 15 (auto extension to Oct 15)	Tax return due date
Assets covered	Financial accounts only	Financial accounts + other assets
Penalty for non-filing	Up to $16,117+ per account/year	$10,000+ per year
Criminal penalties	Yes	Yes

You may need to file both. The two forms serve different agencies and have different scopes. Filing one does not satisfy the other.

Common Situations

Expats and Digital Nomads

U.S. citizens and resident aliens must file regardless of where they live. If you use the foreign earned income exclusion to reduce your taxable income, you still must report your foreign accounts. Make sure you understand your tax filing status — it affects FATCA thresholds.

Joint Accounts

If you have joint ownership of a foreign account with a non-U.S. person (such as a foreign spouse), the entire account balance counts toward your threshold, not just your share.

Signatory Authority Only

If you have signature authority over a foreign account — for example, a company account at work — you must report it on FBAR even if you have no financial interest in it.

Foreign Retirement Accounts

Foreign pensions, superannuation funds, and retirement accounts are generally reportable on both FBAR and Form 8938. Tax treaty provisions may exempt the income from current U.S. taxation, but they do not eliminate the reporting requirement.

What to Do If You Have Unfiled FBARs

If you have past-due FBARs, the IRS offers several paths to come into compliance. Do not ignore the issue — the penalties for non-filing far exceed the cost of getting help from a CPA or enrolled agent:

Streamlined Filing Compliance Procedures

For taxpayers whose failure to file was non-willful:

• Domestic filers: File 3 years of amended returns + 6 years of FBARs, pay a 5% miscellaneous offshore penalty
• Foreign filers: File 3 years of returns + 6 years of FBARs with no penalty

Delinquent FBAR Submission Procedures

If you have no unreported income and are otherwise compliant:

• File late FBARs with a statement explaining why they are late
• No penalty if the IRS has not already contacted you

Voluntary Disclosure

For willful violations, the IRS Voluntary Disclosure Practice allows you to come forward before being investigated, which avoids criminal prosecution (though civil penalties still apply).

DIY Filing Checklist

Gathering Information

For each foreign account, you need:

• Financial institution name and address
• Account number
• Type of account (bank, securities, other)
• Maximum account value during the year (in the foreign currency)
• Currency type and exchange rate

Exchange Rates

Use the Treasury Department’s end-of-year exchange rate for FBAR (available at the Treasury Reporting Rates of Exchange). For Form 8938, use the exchange rate on the last day of the tax year.

Filing Steps

1. List all foreign financial accounts and their maximum balances
2. Calculate the aggregate maximum value — if over $10,000, FBAR is required
3. Check FATCA thresholds based on your filing status and residency
4. File FBAR electronically at the BSA E-Filing System by April 15 (or Oct 15)
5. Attach Form 8938 to your tax return if thresholds are met
6. Keep records for at least 5 years (FBAR) or 6 years (Form 8938)
