Chapter 3 withholding applies only to payments made to a payee that is a foreign person. It does not apply to payments made to U.S. persons.
Usually, you determine the payee’s status as a U.S. or foreign person or, if you are making a withholdable payment to an entity (or are an FFI making a payment to an account holder), the payee’s chapter 4 status, based on the documentation that person provides. See Documenta- tion , discussed later. However, if you have received no documentation or you cannot reliably associate all or a part of a payment with documentation upon which you can rely, then you must apply certain presumption rules, dis- cussed later.
Chapter 4 withholding applies to withholdable payments made to an entity payee that is an FFI unless the withholding agent is able to treat the FFI as a participating FFI, deemed-compliant FFI, or exempt beneficial owner. Chapter 4 withholding also applies to withholdable payments made to a passive NFFE that fails to identify its substantial U.S. owners (or certify that it does not have any substantial U.S. owners). You must establish the payee’s chapter 4 status to determine if withholding applies by applying the documentation requirements of chapter 4, generally by obtaining a Form W-8 (or, under an applicable IGA, a similar agreed form) associated with the payment, or other documentation for payments made outside of the United States on offshore obligations. See Regulations section 1.1471-3(d) for details on these documentation requirements. Withholding under chapter 4 also applies to account holders of a participating FFI or registered deemed-compliant FFI that the FFI is required to treat as recalcitrant account holders.
This section applies to both chapters 3 and 4 except where otherwise indicated and except where the text clearly applies to one or the other (for example, reduced rates and exemptions under income tax treaties).
