How long does it take to get an IRIS TCC?

Publication 5717 (Rev. 9-2026) says to allow up to 45 calendar days for application processing.

Can I use my FIRE TCC in IRIS?

No, according to PayrollOrg's 8 October 2026 report on the move from FIRE to IRIS. IRIS needs its own TCC.

What is the latest day to apply for the 2027 season?

Friday 18 December 2026 leaves exactly 45 calendar days before the Monday 1 February 2027 due date for Form 1099-NEC. The IRS wording is "up to", so earlier is safer.

IRIS TCC processing time: up to 45 days

Publication 5717 (Rev. 9-2026): "Allow up to 45 calendar days for application processing."

A TCC (transmitter control code) is the five-character code that lets you sign in to the IRIS Taxpayer Portal and file. Without it there is no template to download and nothing to upload to.

Fact	Date or number	Source
Processing time	Up to 45 calendar days	Publication 5717 (Rev. 9-2026), section 2.2.1
1099-NEC due for tax year 2026	Monday 1 February 2027	Form instructions revised 12/2026, weekend rule
45 calendar days before that	Friday 18 December 2026	Our calculation
A FIRE TCC works for IRIS	No	PayrollOrg, 8 October 2026, which also reports up to 45 business days
Forms the application supports	"the Form 1099 Series (includes Forms 1042-S, 1097, 1098, 1099, 3921, 3922, 5498, and W-2G)"	IRS page: IRIS application for TCC

"Up to" is the IRS's wording and not a promise in either direction. An application sent after Friday 18 December 2026 may still come back in time, and one sent before may not.

The application steps in Publication 5717

Go to the IRS page IRIS Application for TCC and select Access IRIS application for TCC.
Sign in or create an account.
Select Individual on the Select Your Organization page.
Select New Application, then IRIS Application for TCC.
Complete and submit the application. Each responsible official signs with a 5-digit PIN.
When the application shows Completed and a TCC has been issued, open the IRIS Taxpayer Portal from the IRS page E-file information returns with IRIS.

While you wait, the list can be made ready. Perfrow has a practice mode that checks every row against the published column list, so the only step left when the TCC arrives is to drop in the real template.

Fix the whole file at once

Drop in your blank IRIS template and your spreadsheet. Perfrow cleans every row, tells you which ones need you, and writes CSVs of at most 250 records. It runs in your browser, so names and TINs stay on your computer.
