The Internal Revenue Service (IRS) has issued a reminder to information return filers about the upcoming transition from the Filing Information Returns Electronically (FIRE) system to the new Information Returns Intake System (IRIS) before the 2027 filing season. Filers currently using FIRE must prepare to switch to IRIS, as FIRE will no longer accept submissions after its November maintenance window.
Key deadlines for FIRE users include November 1, 2026, for submitting test information returns, and November 9, 2026, for making changes to Transmitter Control Codes (TCC) applications. The final day to file information returns through the FIRE system is November 19, 2026, at 3 p.m. ET.
IRIS, a modernized system launched in 2023, will support all forms previously handled by FIRE starting in 2027. It offers two filing channels: the IRIS Taxpayer Portal, a free web-based system for up to 100 returns, and IRIS Application to Application for larger volumes. Filers should complete an IRIS Application for TCC and review available guidance to prepare for this change.
