FATCA (FATCA)

FATCA, the US Foreign Account Tax Compliance Act, requires foreign financial institutions to identify accounts held by US taxpayers and report them to the IRS, directly or through their own government. Institutions that do not take part face 30 percent withholding on certain US-source payments.

Also called: Foreign Account Tax Compliance Act · FATCA reporting · FATCA withholding · Chapter 4 withholding

FATCA was enacted in 2010 as part of the Hiring Incentives to Restore Employment (HIRE) Act and forms Chapter 4 of the Internal Revenue Code. Its target is tax evasion by US persons holding money through accounts abroad. A participating foreign financial institution must report accounts held by US taxpayers, and by foreign entities in which US taxpayers hold a substantial ownership interest. An institution that does not participate is subject to 30 percent withholding on certain US-source payments made to it, which makes opting out expensive for any bank that holds US securities or deals in dollars.

Most countries implement FATCA through an intergovernmental agreement with the US Treasury. Under a Model 1 agreement, institutions report to their own tax authority, which passes the information to the IRS. Under a Model 2 agreement, the government directs its institutions to report directly to the IRS under an agreement with it. FATCA became the template for the multilateral Common Reporting Standard, which the United States itself has not adopted.

FATCA also has an individual side: US taxpayers whose specified foreign financial assets exceed reporting thresholds, starting at US$50,000, must attach Form 8938 to their tax return. For a bank or fintech onboarding customers outside the United States, FATCA is why account opening asks whether the customer is a US person and collects an IRS Form W-9 or W-8, and why entity customers are asked about their beneficial owners. It is a core part of the reporting that changed offshore banking.

In practice

FATCA is a US regime with its own definitions, forms and registration. A firm compliant with CRS is not automatically compliant with FATCA, and the reverse.

Example

A bank in a Model 1 jurisdiction opens an account for a local company 40 percent owned by a US citizen. The bank records the owner's US taxpayer number, reports the account balance each year to its own tax authority, and that authority forwards the data to the IRS.
