Can the same TCC be used for both FIRE and IRIS?

Eric Updated by Eric

Transmitter Control Codes (TCC) are five-character, alphanumeric codes required by the IRS to e-file information returns. There are different types of TCC's and they are not interchangeable.

1099 forms, etc. can be filed with either FIRE or IRIS. The IRS announced that FIRE will not be available starting January 1, 2027.

How did we do?

Are you sure you filed ALL your 1099's on IRS's tricky IRIS site?
