According to NIST SP 800-52r2 guidelines, all government agencies, including IRS, should move off these versions and preferably move to TLS version 1.3 (TLS version 1.2 is also acceptable). Based on these guidelines, beginning August 1, 2022, the encryption level for the User Interface (UI) and Application-to-Application (A2A) Channels, for the ACA Assurance Testing System (AATS) and Production Environments will be TLS versions 1.2 and 1.3 exclusively. If you are not currently using TLS version 1.2 or 1.3, we advise you to move to one of these versions as soon as possible (no later than August 1, 2022) to avoid any possible disruption of service. 10/4/2019: AIR no longer supports SHA-1 from the accepted Signature and Digest methods used to digitally sign ISS-A2A transmissions.
