Keep your existing FIRE export. Eisen handles the move to IRIS.

Eisen converts your FIRE file, checks every record against IRIS business rules, and files your 1099s with the IRS. Your team keeps its current export and Eisen handles the new IRIS validations. Catch IRIS errors before you file.

The IRS FIRE system stops accepting returns November 19, 2026, at 3 p.m. ET. Transition is not optional. Tax year 2026 1099s must go through IRIS.

From your FIRE file to an approved IRIS submission.

Start with your existing FIRE file.

Upload the export from your reporting system. Eisen converts it to the IRIS format.

Catch problems before you file.

Eisen flags records that would fail IRIS validation so your team can correct them before submission.

Know what the IRS accepted.

When a transmitter files for you, IRIS only shows submission details to the transmitter. Eisen's dashboard gives your team that view.

No IRIS TCC application required.

A FIRE TCC doesn't carry over to IRIS, but with Eisen-managed filing you don't need a new one. Eisen transmits under its own IRIS TCC, so your institution skips the IRS application and approval process entirely. Eisen handles the full production process: validating data against IRIS business rules, preparing recipient statements for mail or digital delivery, and filing through to IRS acceptance.

Eisen supports each major form.

1099-INT, 1099-DIV, 1099-MISC, 1099-NEC, 1099-R, 1099-K, 1099-B, 1099-DA, 1099-C, 1099-A, 1099-Q, 1098, 1098-E, 5498, 5498-ESA, 1042-S
