New sign-in options
E-Services has new, secure sign-in options.
- Login.gov – Created and maintained by the U.S. government.
- ID.me – Created and maintained by a technology provider.
If you don’t have a Login.gov or ID.me account, you’ll need to create one to access the IRS Secure Messaging platform.
If you have a Login.gov or ID.me account, no action is necessary. You can use it to sign in.
The following table lists XML schemas, business rules and release memorandum for the Information Returns Intake System (IRIS).
Throughout the year, multiple versions of business rules and schemas may be in use at the same time. For each version of IRIS, the tables reflect the effective dates in the production system and the Assurance Testing System (ATS).
For questions, contact the Help Desk at 866-937-4130.
How to get schemas and business rules
To receive IRIS schemas and business rules, you must have an IRIS Transmitter Control Code (TCC).
With an IRIS TCC, you can get schema packages in your e-Services mailbox.
Your e-Services mailbox is part of the Secure Object Repository (SOR).
