International Data Exchange Service (IDES) – User Guide

The IRS has made the user guide for the international data exchange service (IDES) available. This guide is intended to serve as a tool for all parties involved in the FATCA data exchange. FATCA was created to improve transparency and address tax non-compliance by U.S. taxpayers. FATCA requires certain foreign financial institutions (FFIs) to report certain information about its U.S. accounts. Accounts held by owner-documented FFIs (ODFFI). Also certain aggregate information concerning account holders that are recalcitrant account holders. Lastly, for a transitional period, accounts held by nonparticipating FFIs. 

Generally, FFIs will commit to these reporting requirements by registering with the IRS and signing an agreement with the IRS; however, the FFI agreement does not apply to FFIs under a Model 1 IGA. In most cases, FFIs that do not register with the IRS will be subject to 30% withholding on certain U.S. source payments (unless an exception applies).

Purpose of the User Guide

This guide is intended to serve as a tool for FIs, direct reporting NFFEs, sponsoring entities, non-GIIN filers, and Host Country Tax Authorities (HCTAs) who transmit data through the International Data Exchange Service (IDES). The document assumes that the reader is familiar with the FATCA regulations and is experienced with extensible markup language (XML) and schema technology. For the purpose of this document, direct reporting NFFEs, sponsoring entities, non-GIIN filers and trustees of trustee-documented trusts should follow the instructions set forth for FIs. Additionally, the term “U.S. withholding agent” includes a territory FI treated as a U.S. person.
