Digital certificates bind digital information to physical identities and provide non-repudiation and data integrity. Before you begin the IDES enrollment process, each entity should obtain one valid digital certificate issued by an approved certificate authority (CA). IDES stores your public key and related digital certificate. IDES only recognizes and accepts digital certificates issued by IRS approved certificate authorities, listed below.

The public certificate should be included in the FATCA data packet (transmission archive) to the IRS.Note: The public/private key pairs used for encryption for FATCA filings have an expiration date.
