E-Services transitioned the AIR Production application to a modernized sign-in system that requires users to register and sign in with ID.me to access the e-Services suite of online applications.

ID.me is an account created, maintained, and secured by a technology provider.

The UI AATS URL changed to a new address. The existing UI AATS URL will redirect users to the new address until further notice. Please start using the new AATS URL effective immediately.
The AIR Production URL address will remain the same.

Transport Layer Security (TLS) versions 1.0 and 1.1 have been deprecated by the industry. 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. The ISS-A2A Gateway accepts SHA-256, SHA-384 and SHA-512 algorithms during the validation of WS-Security.
