1099 FIRE to IRIS: What Changes Before November 2026
The IRS is replacing its Filing Information Returns Electronically (FIRE) system with the Information Returns Intake System (IRIS) for e-filing 1099s. The FIRE system will close on November 19, 2026, at 3 p.m. ET, not December 31, 2026, as some sources incorrectly state. After January 1, 2027, IRIS will be the sole electronic filing system for all information returns, including prior years and corrections. Current FIRE users must apply for a new IRIS Transmitter Control Code, as existing FIRE codes do not carry over.
