Contained within the Hiring Incentives to Restore Employment Act (HIRE Act), the Foreign Account Tax Compliance Act (FATCA) has three core elements: • enhanced due diligence • broader information reporting, and • a potential withholding tax on US source payments The main purpose of the FATCA provisions is to obtain information reporting on US-owned offshore accounts, and so imposes broad disclosure and reporting requirements on foreign financial institutions (FFIs) (and other foreign entities). See Title V, Subtitle A of the HIRE Act, 111 PL 147, 124 Stat 71. Identifying what is, and what is not, an FFI is essential to understanding the scope and application of FATCA. This Practice Note examines: • what an FFI is, as broadly defined in the lengthy and detailed set of FATCA regulations (the US Treasury Regulations) • what the exceptions from the definition of FFI are, and • what deemed-compliant FFIs are For a detailed introduction to FATCA, and the due diligence, reporting and withholding obligations that it imposes on FFIs
