FATCA, the Foreign Account Tax Compliance Act, is the US law that built the global automatic exchange of financial account information. It was enacted on March 18, 2010 as part of the Hiring Incentives to Restore Employment (HIRE) Act and added Chapter 4 (sections 1471 through 1474) to Subtitle A of the Internal Revenue Code. The mechanism is direct: any foreign financial institution that wants to receive US-source income without losing 30 percent at the door must agree to identify and report US-owned accounts. For US companies paying foreign entities and for US persons with foreign accounts, FATCA shapes the documentation, the bank questions, and the year-end reporting.
How FATCA Works
FATCA operates through three integrated layers:
- Section 1471 (FFIs). Imposes 30 percent withholding on withholdable payments to a foreign financial institution unless it enters into an FFI agreement with the IRS, meets the requirements of an applicable intergovernmental agreement (IGA), or qualifies as deemed-compliant or exempt beneficial owner.
- Section 1472 (NFFEs). Imposes 30 percent withholding on withholdable payments to a non-financial foreign entity unless the entity certifies that it has no substantial US owners or identifies them on Form W-8BEN-E.
- Section 1473 (Definitions). Defines withholdable payment as a US-source FDAP payment and certain gross proceeds, and defines US person and US owner.
A “withholdable payment” generally includes US-source FDAP income (interest, dividends, rents, royalties, salaries, annuities, and similar) and was originally scheduled to include gross proceeds from the sale of property that could produce US-source interest or dividends. The IRS has indefinitely deferred the gross-proceeds component under Notice 2024-78 and related guidance.
Who Must Comply
- Withholding agents. Any US (or foreign) person that has control, receipt, custody, or disposal of a withholdable payment is a withholding agent and must determine the Chapter 4 status of each payee.
- Foreign financial institutions. Banks, custodial institutions, investment entities, certain insurance companies, and holding companies that hold financial assets for others. They must comply directly with an FFI agreement or through an IGA.
- Non-financial foreign entities. Any foreign entity that is not an FFI. Active NFFEs (those with mostly active business income) face lighter documentation. Passive NFFEs must disclose substantial US owners.
- US persons with foreign accounts. US individuals and entities holding specified foreign financial assets must report them on Form 8938 with their federal income tax return, separately from the FBAR on FinCEN Form 114.
Reporting and Withholding
The FATCA cycle for a withholding agent:
- Collect Chapter 4 documentation. For a foreign entity payee, this is typically Form W-8BEN-E. For a foreign individual, Form W-8BEN.
- Verify the FATCA status (participating FFI, registered deemed-compliant FFI, exempt beneficial owner, active NFFE, passive NFFE with disclosed substantial US owners).
- Apply 30 percent FATCA withholding to a payee that fails to provide valid Chapter 4 documentation or whose status is non-compliant.
- File annual Form 1042 and Form 1042-S reporting payments and withholding to foreign payees.
FFIs report annually under the IGA (or directly to the IRS for Model 2 IGAs) on Form 8966 or its IGA equivalent. The information is then exchanged automatically with the IRS.
Penalties
- 30 percent FATCA withholding. The most direct consequence is the 30 percent cliff itself on withholdable payments. This is irrecoverable except by a refund claim filed by the beneficial owner where the underlying income was not actually subject to Chapter 4 withholding.
- Withholding agent liability. A withholding agent that fails to withhold on a non-compliant FFI is personally liable for the amount that should have been withheld under section 1474, plus interest and penalties.
- Form 8938 penalties. A US person that fails to file Form 8938 faces an initial 10,000 dollar penalty plus continuation penalties up to 50,000 dollars under section 6038D.
- Information return penalties. Failure to file or furnish accurate Forms 1042-S to foreign payees attracts the section 6721 and 6722 penalty stack.
Common Pitfalls
- Treating a W-8BEN-E without a FATCA status as adequate. The Chapter 3 fields are not enough. The Chapter 4 box must be completed for the form to support non-withholding on a withholdable payment.
- Confusing FATCA with chapter 3 treaty rates. A treaty rate under Chapter 3 does not eliminate FATCA withholding under Chapter 4. The FATCA cliff is decided first.
- Forgetting Form 8938. US persons holding specified foreign financial assets above the thresholds must file Form 8938 with their return. The FBAR (FinCEN Form 114) is a separate filing with different scope and thresholds.
- Stale documentation. W-8 forms expire (generally end of the third calendar year following signature). Documentation programs that do not refresh expose the withholding agent to underwithholding liability.
- Form W-8BEN-E: the FATCA documentation form for foreign entities.
- Form W-8BEN: the FATCA and chapter 3 form for foreign individuals.
- Form W-9: the US-person form that closes out FATCA risk for that payee.
- BSA Reporting: the parallel FBAR regime for US persons with foreign accounts.
- DAC7: the EU analog regime for digital platform income reporting.
