eCMS v.4.2 Fix Pack 3 HF315: 2026 1099 Electronic Filing and IRIS Requirements
Our team is beginning the installation of eCMS v.4.2 Fix Pack 3 HF315 for both on-premise and hosted customers.
The primary purpose of HF315 is to provide access to the new 1099 electronic filing functionality and requirements for the IRS Information Returns Intake System (IRIS).
Action Required After Installing HF315
After HF315 has been installed, you will need to restore the updated 1099 eForm templates in eCMS.
From eCMS, go to:
Tools > eForm Viewer > Edit Templates
When prompted, select and restore the following templates:
Form 1099-MISC
Form 1099-NEC
Form 1099-BROKER
Form 1099-DIVIDENDS
Form 1099-INT
Restoring these templates will provide access to the updated 2026 eForms needed for 1099 processing.
New IRIS Electronic Filing Functionality
HF315 also introduces a new menu option in eCMS:
A/P > Annual > IDI 1099 Register/IRIS Electronic Filing (APPM12-11)
The IRS retired the previous FIRE (Filing Information Returns Electronically) system at the end of the 2025 reporting year. Beginning with the 2026 reporting year, 1099 electronic files will be submitted through the IRS IRIS (Information Returns Intake System).
CGC is currently preparing an updated year-end documentation guide for 1099 processing, including instructions for using the new IRIS electronic filing process. Once available, the documentation will be posted on the CGC Portal under:
Knowledge Center > eCMS Quarter-End and Year-End Documentation > IRIS Filing
CGC Portal – Quarter-End and Year-End Documentation
Important: Obtain Your IRS Transmitter Control Code (TCC)
On July 10, 2026, CGC sent a communication emphasizing the importance of contacting the IRS and submitting an application for a Transmitter Control Code (TCC). A TCC is required to submit 1099 files through the IRIS system.
If you have already obtained your TCC, you can begin creating and submitting test files through IRIS for the 2025 reporting year.
We strongly encourage you to complete this testing now. Testing early will give you time to identify and resolve any setup or filing issues before year-end.
If you have not yet started the IRS TCC application process, please begin immediately. The IRS has indicated that processing and feedback may take approximately 4–6 weeks.
Tutorials for completing the IRS TCC application, including a CGC-specific version of the tutorial, are available on the CGC Portal:
Knowledge Center > eCMS Quarter-End and Year-End Documentation > IRIS Filing
CGC Portal – IRIS Filing Documentation
2026 File Changes
At this time, the IRS has not yet provided the final file changes for the 2026 reporting year. CGC will incorporate the 2026 requirements into eCMS as soon as the applicable specifications are made available by the IRS.
If you have questions or need assistance, please open a Support Ticket with CGC Support.
Thank you,
