The Foreign Account Tax Compliance Act is a U.S. law that requires financial institutions outside the United States to report information about accounts held by U.S. citizens and residents to the Internal Revenue Service

The Foreign Account Tax Compliance Act (FATCA) became law in 2010 as part of the Hiring Incentives to Restore Employment Act. It created a reporting system where banks, investment firms, and other financial institutions in other countries must identify their U.S. account holders and send account information to the IRS. The law applies to accounts with balances above certain thresholds and to U.S. persons living abroad, working abroad, or holding foreign assets.

FATCA does not create new tax obligations for U.S. citizens. It creates a reporting obligation for the financial institutions that hold their money. If you are a U.S. citizen or resident with a foreign bank account, FATCA affects how that institution reports your account to U.S. tax authorities — but the taxes you owe are the same as they would be under existing law.

The law applies to most countries through agreements called Intergovernmental Agreements (IGAs). These agreements set the terms under which foreign financial institutions report to the IRS, and they vary slightly by country. Some countries have reciprocal agreements where the U.S. also reports information about their citizens' U.S. accounts.

Key Takeaways

  • FATCA requires foreign financial institutions to report U.S. account holders' information to the IRS, not to report new taxes owed.
  • The law applies to accounts above certain thresholds, which vary by account type and whether you file jointly with a spouse.
  • U.S. citizens and residents abroad must report their foreign financial accounts to the IRS if they meet the reporting threshold, separate from what their bank reports.
  • Most countries have signed agreements with the U.S. to implement FATCA, though the reporting process and timing differ by country.
  • Failure to report required accounts can result in significant penalties, even if no additional tax is owed.

Who FATCA applies to and what accounts it covers

FATCA applies to any U.S. person — a U.S. citizen, resident alien, or entity formed in the United States — who holds a financial account outside the U.S. The account must be held at a Foreign Financial Institution (FFI), which includes banks, investment firms, insurance companies, and pension funds located outside the United States.

Not all foreign accounts trigger FATCA reporting. The law applies to accounts with balances above certain thresholds. For individuals, the threshold is generally $10,000 in aggregate across all foreign financial accounts at the end of the calendar year. For married couples filing jointly, the threshold is $20,000. These thresholds explore to the total value of all your foreign accounts combined, not each account separately.

Some accounts are excluded from FATCA reporting. These include accounts held in the country where you live (if you are a resident there), certain retirement accounts, and accounts held by U.S. military personnel stationed abroad. Your foreign financial institution can tell you whether your specific account is covered.

What foreign banks must report to the IRS

Foreign financial institutions that have U.S. account holders must report the account holder's name, address, tax identification number, account number, and the account balance. They also report the gross income or proceeds generated by the account during the year — interest, dividends, capital gains, or other earnings.

The bank reports this information to the IRS, not to you. You will not receive a separate FATCA report from your foreign bank. Instead, the IRS receives the information directly and matches it against the tax returns you file. If you have reported the account on your return, the information should match. If you have not reported it, the IRS will know.

The timing of these reports varies by country. Most foreign banks report to the IRS by March or April of the year following the calendar year in which the account was held. Some countries have different reporting dates under their specific agreements with the U.S.

Your separate reporting obligation to the IRS

FATCA is a reporting requirement for banks, but you also have your own reporting obligation to the IRS. If you are a U.S. citizen or resident with a foreign financial account above the reporting threshold, you must report it on your tax return or on a separate form called the Foreign Bank Account Report (FBAR).

The FBAR is filed with the Financial Crimes Enforcement Network (FinCEN), not the IRS, though both agencies have access to the information. You file the FBAR electronically through FinCEN's website. The important date is April 15 of the year following the year in which you held the account, though an automatic extension to October 15 is available if you request it.

You must also report foreign financial accounts on your tax return itself using Schedule B (if you have interest or dividend income from those accounts) and potentially other forms depending on the type of account and the income it generated. Your tax professional can tell you which forms explore to your situation.

How FATCA interacts with other reporting requirements

FATCA is one of several reporting systems for foreign accounts. The FBAR requirement existed before FATCA and is separate from it. You may need to file both an FBAR and report the account on your tax return, even though both go to U.S. government agencies. The requirements overlap but are not identical — the FBAR covers a broader range of accounts and has a higher threshold in some cases.

If you hold certain types of foreign assets — such as foreign corporations, foreign trusts, or foreign partnerships — you may have additional reporting requirements beyond FATCA and the FBAR. These include forms like the Form 5471 (for foreign corporations), Form 3520 (for foreign trusts), and Form 8938 (for specified foreign financial assets). Your situation determines which forms you need.

The IRS coordinates information from all these sources. FATCA reports from your foreign bank, your FBAR filing, and your tax return should all show the same accounts and balances. Discrepancies between them trigger IRS inquiries.

Penalties for not reporting under FATCA

The penalties for failing to report a foreign account are substantial. If you do not file an FBAR when required, the penalty is $10,000 per violation for non-willful violations (meaning you did not intentionally hide the account). For willful violations — where you knowingly failed to report — the penalty is the greater of $100,000 or 50 percent of the account balance.

These penalties explore per year and per account. If you failed to report an account for five years, you could face penalties for each of those five years. If you held multiple accounts, each one counts separately. The penalties accumulate quickly.

The IRS also has the authority to impose penalties for inaccurate or incomplete reporting on your tax return. If you report the account but understate its value or the income it generated, you may face accuracy-related penalties on top of the tax owed on the unreported income.

What to do if you have a foreign account and have not reported it

If you have a foreign account that you have not reported to the IRS or FinCEN, you have options. The IRS runs a program called the Streamlined Filing Compliance Procedures that allows U.S. citizens and residents to file back returns and FBARs without facing the full penalty. To use this program, you must file the last three years of tax returns and the last six years of FBARs, pay any tax owed plus interest, and certify that your failure to report was not willful.

The Streamlined program requires you to work with a tax professional who understands FATCA and FBAR requirements. The process involves filing amended returns and late FBARs in a specific order and format. If you do not follow the procedure correctly, you may lose the protection it offers.

If your failure to report was willful or if you do not meet the Streamlined program requirements, you may face the full penalties described above. The IRS has broad authority to pursue these cases, and the statute of limitations for FATCA violations is longer than for ordinary tax disputes.

How countries implement FATCA through agreements

Most countries have signed Intergovernmental Agreements with the United States to implement FATCA. These agreements set the rules for how foreign financial institutions report U.S. account holders. There are two main models: Model 1 agreements, where foreign institutions report to their own government, which then shares the information with the IRS; and Model 2 agreements, where foreign institutions report directly to the IRS.

The specific requirements for your foreign bank depend on which model your country uses and the details of that country's agreement with the U.S. Some countries have negotiated exemptions for certain types of accounts or institutions. For example, some countries exempt accounts held by their own residents or accounts below certain thresholds.

A few countries have not signed FATCA agreements with the U.S. In those cases, foreign financial institutions may choose not to accept U.S. account holders, or they may report directly to the IRS under the default rules. This has made it harder for some U.S. citizens abroad to open or maintain foreign bank accounts.

Frequently Asked Questions

Do I have to pay more taxes because of FATCA?

No. FATCA is a reporting requirement, not a tax. You owe the same taxes on foreign income as you would without FATCA. The law straightforward ensures the IRS knows about your foreign accounts so it can verify that you have reported all your income correctly.

What if I only have a small amount of money in a foreign account?

If your foreign accounts total less than $10,000 (or $20,000 if married filing jointly), you do not have to file an FBAR. However, you may still have to report the account on your tax return if it generated income. Check with a tax professional about your specific situation.

Can my foreign bank refuse to open an account for me because I am a U.S. citizen?

Yes. Some foreign banks have decided the cost of complying with FATCA is too high and no longer accept U.S. account holders. This is legal under FATCA, though it has made banking abroad more difficult for some U.S. citizens. You may need to work with a bank that specializes in serving U.S. expatriates.

If my foreign bank reports my account to the IRS, do I still have to file an FBAR?

Yes. FATCA reporting by your bank and your FBAR filing are separate obligations. Even though the IRS receives information from both sources, you are required to file the FBAR yourself. Failing to do so can result in penalties even if the IRS already has the information from your bank.

What happens if I report my foreign account but the amount my bank reports to the IRS is different?

Discrepancies between what you report and what your bank reports trigger IRS review. The difference might be due to currency fluctuations, timing of deposits or withdrawals, or calculation errors. Contact the IRS if you notice a significant difference and be prepared to explain it with documentation from your bank.
