The Foreign Account Tax Compliance Act (FATCA) is a U.S. law that requires banks and financial institutions outside the United States to report information about American account holders to the IRS.

FATCA, passed in 2010, creates a system where foreign financial institutions must identify U.S. citizens and report their account details—including balances and transaction information—directly to the Internal Revenue Service. If a foreign bank or investment firm does not comply, it faces a 30 percent withholding tax on certain U.S. payments it receives. The law applies to you if you are a U.S. citizen or resident alien with financial accounts outside the country, regardless of where you live.

The core requirement is straightforward: foreign financial institutions must know who their American customers are and tell the IRS about them. This means your foreign bank, brokerage, insurance company, or pension fund likely already reports your account information to U.S. tax authorities. You do not need to do anything to make this happen—the institution handles the reporting on its own schedule, usually once per year.

Key Takeaways

  • Foreign banks and investment firms must report U.S. account holders' information to the IRS under FATCA, with most reporting happening automatically once per year.
  • You may need to file additional tax forms (FBAR or FATCA Form 8938) if your foreign accounts exceed certain thresholds, even if you owe no U.S. tax.
  • FATCA applies to U.S. citizens and resident aliens living anywhere in the world, including those who have not lived in the United States for years.
  • Failure to report required foreign accounts can result in civil penalties starting at $10,000 per account per year, plus potential criminal charges.
  • Many countries have signed agreements with the U.S. to exchange financial information under FATCA, making enforcement consistent across borders.

Who FATCA applies to and what triggers reporting

FATCA applies to any U.S. citizen or resident alien—including green card holders—who has a financial account at a foreign institution. This includes bank accounts, investment accounts, retirement accounts, insurance policies with cash value, and pension funds held outside the United States. The law does not care where you live; if you are a U.S. tax resident, FATCA reaches you.

The threshold for your own reporting obligations is separate from the bank's obligation. If your foreign financial accounts total more than $10,000 at any point during the calendar year, you must report them to the U.S. government. This $10,000 threshold applies to the combined value of all your foreign accounts, not each account individually. A single account worth $15,000, or five accounts worth $2,500 each, both trigger the reporting requirement.

Some accounts are exempt from FATCA reporting. These include accounts held by the foreign government itself, accounts at certain international organizations, and accounts at some U.S. military banking facilities overseas. Your foreign employer's pension plan may also be exempt if it meets specific conditions. Check with your financial institution or a tax professional if you are unsure whether a particular account counts.

The two main reporting forms you may need to file

If your foreign accounts exceed $10,000, you will likely need to file one or both of two forms with the U.S. government: the FBAR (FinCEN Form 114) and FATCA Form 8938. These are separate requirements with different thresholds and deadlines, and both must be filed even if you owe no U.S. income tax.

The FBAR (Report of Foreign Bank and Financial Accounts) is filed with the Financial Crimes Enforcement Network (FinCEN), not the IRS. You file it if you have foreign financial accounts totaling more than $10,000 at any time during the year. The FBAR is due April 15 of the following year, with an automatic extension to October 15 if you request it. You file the FBAR electronically through FinCEN's website; there is no paper option.

The FATCA Form 8938 (Statement of Specified Foreign Financial Assets) is filed with your tax return to the IRS. The threshold depends on your filing status and whether you live in the United States. If you live abroad and are single, you file Form 8938 if your foreign accounts exceed $200,000 on the last day of the year or $300,000 at any point during the year. If you live in the U.S., the thresholds are lower: $400,000 on the last day of the year or $600,000 at any point during the year. Married couples filing jointly have higher thresholds. Form 8938 is due with your tax return, typically April 15.

You may need to file both forms. The FBAR and Form 8938 cover similar ground but have different rules about which accounts count and what information you must report. Many people who report foreign accounts file both to ensure full compliance.

How foreign banks report your information to the IRS

Most foreign financial institutions have already signed agreements with the U.S. Treasury to exchange account information automatically. Under these agreements—called Intergovernmental Agreements (IGAs)—foreign banks report U.S. account holder information to their own tax authority, which then shares it with the IRS. This happens without you doing anything.

The reporting typically occurs once per year, usually in the spring or early summer following the calendar year in which the accounts were held. Your bank sends the IRS your name, address, account number, account balance, and gross income or proceeds from the account. The IRS then matches this information against your tax return to see if you reported the income correctly.

Some countries do not have IGAs with the United States, or their agreements are newer and still being implemented. In those cases, the foreign bank may report directly to the IRS or may not report at all. However, the IRS can still obtain information about your accounts through other means, including direct requests to foreign banks or information-sharing agreements with other countries.

Penalties for not reporting foreign accounts

The penalties for failing to report foreign accounts are severe and can accumulate quickly. If you do not file the FBAR when required, the civil penalty is $10,000 per violation per year. If the failure is deemed willful—meaning you knew you were supposed to file and chose not to—the penalty can be the greater of $100,000 or 50 percent of the account balance at the time of the violation. These penalties apply per account, so multiple unreported accounts multiply the exposure.

Failure to file Form 8938 carries a $10,000 penalty for each year you do not file, with an additional $10,000 penalty for each 30-day period you remain non-compliant after the IRS notifies you, up to $50,000 per year. If the failure is willful, the penalty increases to $10,000 per violation.

Beyond civil penalties, the IRS can pursue criminal charges for willful tax evasion or filing false tax returns. Criminal penalties can include prison time and fines in the hundreds of thousands of dollars. The IRS prioritizes criminal prosecution of cases involving large amounts of unreported income or deliberate concealment of accounts.

What to do if you have unreported foreign accounts

If you have foreign accounts you did not report in prior years, you have options to come into compliance without facing the full penalty. The IRS runs a program called the Streamlined Filing Compliance Procedures, which allows you to file back tax returns and FBARs for the past three years (or six years for FBARs, depending on the version you use) with reduced or eliminated penalties.

To use the Streamlined Procedures, you must file amended returns for the prior years, file all required FBARs and Forms 8938, and certify that your failure to report was not willful. You will owe back taxes plus interest, but the penalties are typically waived. This program is available to U.S. citizens living abroad and those living in the United States, though the rules differ slightly.

If you cannot use the Streamlined Procedures—for example, because the IRS has already contacted you about the accounts—you can still file amended returns and FBARs. The penalties will be higher, but filing voluntarily before the IRS discovers the accounts usually results in lower penalties than being caught. Consult a tax professional who specializes in international tax issues before taking action, as the rules are complex and mistakes can be costly.

How FATCA affects your daily banking and investments

For most people with foreign accounts, FATCA creates no day-to-day disruption. Your bank continues to operate normally, and you access your account as usual. The reporting happens behind the scenes, and you only see it if you receive a notice from the IRS or if you are preparing your own tax return.

However, FATCA has made it harder for some Americans to open and maintain foreign bank accounts. Some foreign banks have closed accounts held by U.S. citizens because the compliance burden is too high. Others charge higher fees to American customers to cover the cost of FATCA reporting. If you are moving abroad or opening a foreign account, expect to provide extensive documentation proving your identity and tax residency status.

FATCA also affects how foreign financial institutions treat U.S. investments. If you own shares in a foreign mutual fund or hold a foreign pension, the fund or pension provider must determine whether you are a U.S. person and report accordingly. Some foreign investment products are no longer available to Americans because the issuer does not want to deal with FATCA compliance.

Frequently Asked Questions

Do I have to file an FBAR if I only have one foreign bank account?

Only if that account totals more than $10,000 at any point during the year. The $10,000 threshold applies to all your foreign accounts combined, not per account. If you have one account worth $15,000, you file the FBAR. If you have one account worth $8,000, you do not.

What if my foreign account is in my spouse's name only?

If you have a legal right to control the account or know about it, you must report it on your FBAR and Form 8938. Accounts held jointly are clearly reportable. Accounts in your spouse's name alone may still be reportable if you can access the funds or if you live in a community property state. Consult a tax professional about your specific situation.

Can I get in trouble for not knowing about FATCA?

Ignorance of the law is not a defense, but it can affect the type of penalty you face. If you did not know you were supposed to file an FBAR, the IRS may treat your failure as non-willful, which carries a lower penalty than willful non-compliance. However, you are still responsible for filing once you become aware of the requirement.

Does FATCA apply if I am a U.S. citizen living permanently abroad?

Yes. FATCA applies to all U.S. citizens and resident aliens regardless of where they live. If you are a U.S. citizen living in another country and have foreign bank accounts, you must still report them to the IRS, even if you do not owe U.S. income tax because of the Foreign Earned Income Exclusion.

What happens if my foreign bank does not report me to the IRS?

You are still required to report your accounts on your FBAR and Form 8938. The bank's failure to report does not relieve you of your obligation. The IRS may discover unreported accounts through other means, including information-sharing agreements with other countries or direct inquiries to foreign banks.
