FATCA Identification Number (FIN) Enrollment Process

There are certain entities, such as U.S. withholding agents (USWA), territory financial institutions (TFI), third party preparers, or commercial software vendors that are not required to have a global intermediary identification number (non-GIIN filers).

A non-GIIN filer is required to obtain a FATCA Identification Number (FIN) to be used in lieu of a GIIN to access IDES for FATCA reporting. The FIN is the 19-character identifier that will be entered in the metadata and FATCA XML message header.

Important FIN Facts

  • A FIN may not be issued via telephone.
  • The contact person (“POC”), who is authorized to obtain a FIN on behalf of the entity, consent to disclosure of tax matters and the publication of the entity’s FIN on the FFI list, must contact the IRS via the technical support page.
  • Entities should obtain a FIN at least 6 business days prior to month end to appear on the FFI list for the following month. For example, in order to appear on the June 1st FFI list, you should obtain a FIN by May 20, 2016.
