The IRS Is Retiring FIRE: What Every Business That E-Files 1099s Has to Do Before November 19

Published October 23, 2026 by Invisible LLC Team · 10 min read

You run a business. You are not an e-filing administrator, and the words "Transmitter Control Code" have never once improved your day.

Unfortunately, one of them is about to expire on you.

The IRS is retiring the Filing Information Returns Electronically system — FIRE — the platform that has carried business 1099 e-filing for decades. It shuts off permanently at 3 p.m. ET on Thursday, November 19, 2026, and from January 1, 2027 the Information Returns Intake System (IRIS) becomes the only electronic channel for information returns, including prior-year filings and corrections. The IRS announced the timeline in IR-2026-99 on August 24, 2026 and publishes the dates on its own FIRE system page.

Key takeaways: If you or anyone acting on your behalf transmits 1099s through FIRE, you need an IRIS Application for TCC in motion now — your FIRE code does not carry over. The date that actually binds most filers is November 9, not November 19. And for a lot of small businesses the correct first move is a five-minute phone call to your payroll or bill-pay provider, because this may not be your problem at all.

This post is about the filing mechanism. If what you're actually looking for is which payments require a 1099 and at what dollar amount, that's a different question and we've written it up separately in the 1099-NEC threshold guide — start there and come back.

Three dates, in the order they will hit you

Straight from the IRS, with the weekday attached so you can put them on a calendar:

Date	Weekday	What happens
November 1, 2026	Sunday	Last day to file test information returns through the FIRE Trading Partner Test System
November 9, 2026	Monday	Last day to make changes to the Information Returns (IR) Application for TCC
November 19, 2026, 3:00 p.m. ET	Thursday	Last day to file information returns through the FIRE system
After January 1, 2027	—	IRIS is the only electronic filing system for information returns, "including current year, prior year, or corrections"

One nuance worth stating out loud, because it will cost somebody a filing: these are system cutoffs, not statutory deadlines. A tax deadline that lands on a weekend or federal holiday shifts to the next business day. A server that gets turned off on a Sunday is just off on Sunday. November 1 is a Sunday and the test system stops accepting returns that day; nothing moves to Monday.

The 3 p.m. ET stamp on November 19 deserves the same literal reading. That is mid-afternoon on a Thursday, not end of day, and not end of day in your time zone.

Is this even your problem? One call usually settles it

Here is the part most coverage of this change skips, and it's the part that matters most to a business with eleven people on the payroll: plenty of small businesses have never touched FIRE and never will.

Three situations, three different answers:

1. Somebody files on your behalf. Your payroll provider, your bill-pay service, your bookkeeper, or your CPA transmits your 1099s using their credentials. In that case the transition is their project, not yours. Most readers in this category do not know which bucket they're in — which is exactly why the call is worth making.

2. You transmit your own returns directly through FIRE. You have a TCC, somebody at your company logs in each January, and that somebody is probably you or your office manager. This is your project, and the clock is the one above.

3. You file on paper, or you file a handful through a commercial service. The IRS has required electronic filing since tax year 2023 for filers with 10 or more information returns in the aggregate, per the IRIS filing page. If you're under ten and filing on paper, nothing here forces your hand this year. If you're over ten and have been relying on a service's portal, ask the service the same question as group one.

The script for the call is short: "Do you transmit our 1099s using your own Transmitter Control Code, or ours? And have you completed your IRIS Application for TCC?" Write down the answer. If the person on the phone doesn't know what you're asking, you've learned something useful about your provider.

What a TCC is, and why November 9 is the real cliff

A Transmitter Control Code is the credential the IRS uses to identify who is sending a batch of information returns. It isn't a login; it's an identifier tied to an application your business filed and the IRS approved.

Here's the fact that catches people: the IRIS TCC is a different code. The IRS describes it as "a 5-digit code [that] identifies your business when you e-file forms. It can only be used for IRIS." Your FIRE-era code does not become an IRIS code. The IRS's own instruction to current FIRE users is to "complete an Information Returns Intake System (IRIS) Application for TCC and transition to IRIS to file tax year 2026 information returns during the 2027 filing season."

So November 19 is the date the old door closes, but November 9 is the date your paperwork has to be settled — it's the last day to make changes to your IR Application for TCC. If something on that application is wrong, stale, or missing a required person, after November 9 you cannot fix it on the old application at all.

And applications are not instant. IRS Topic No. 802 tells filers to "allow 45 days for processing" on an Application for TCC. IRS publications describe the same 45-calendar-day window for the IRIS application, along with the staffing the application requires: a minimum of two Responsible Officials, up to two Authorized Delegates, and at least two Contacts. (Those staffing and processing details come from the IRS's IRIS publications — Pub. 5903 and Pub. 5718 — which are image-based PDFs we could not read directly, so treat the figures as IRS-published and confirm them on screen when you open the application. The November dates and the TCC description above are quoted from IRS web pages read directly.)

Do the arithmetic on that and the conclusion is uncomfortable but clear: if you don't have an IRIS TCC in hand today, 45 days from today lands past the FIRE shutoff. That is survivable — your actual filing obligation for tax year 2026 doesn't arrive until early 2027, and IRIS is where it goes regardless. But it means the application is this week's task, not December's. You will not be able to fall back to FIRE while you wait.

You need an Employer Identification Number to apply, and the application lives at the IRS's IRIS TCC page.

What actually changes when you move to IRIS

The good news is that IRIS is a more usable system than the one it replaces, and for a small filer it may be the first time this chore has been pleasant.

Two ways in. The IRIS Taxpayer Portal is free and web-based. You can "e-file up to 100 returns at a time," entering information manually or uploading a CSV, and the portal will generate payee copies for download and keep a record of what you completed, filed, and distributed. The second channel, IRIS Application to Application (A2A), is built for software developers and third-party transmitters moving "thousands of returns (up to 100 MB at a time)" — if you are reading this as a business owner, you want the portal.

A broader form list than most people expect. IRIS accepts information returns including Forms 1042-S, 1097-BTC, the 1098 series, the 1099 series, 3921, 3922, the 5498 series, and W-2G. Which forms are actually available to you depends on the tax year and processing year you select inside the system.

One thing that is not in scope at all: Forms W-2. W-2s and the W-3 transmittal go to the Social Security Administration, not the IRS, and this change doesn't touch them. For tax year 2026 the General Instructions for Forms W-2 and W-3 set that deadline at February 1, 2027 for both furnishing copies to employees and filing Copy A with the SSA. Different system, different agency, different deadline — don't let the FIRE news scramble your January.

Corrections and prior-year filings

This is the quiet half of the announcement and it's the half that affects the business that files cleanly every year and then finds a mistake in March.

The IRS states that after January 1, 2027, IRIS will be the only information returns electronic filing system, "including current year, prior year, or corrections." There is no grandfathered path back into FIRE to fix a 2025 form. The IRIS portal "lets you file corrections and request automatic extensions," so the capability exists — but it exists there, under a TCC you may not have yet.

Practical consequence: if you have an open correction you have been meaning to get to, the cleanest outcome is to finish it in FIRE before November 19. Anything you don't finish moves to IRIS with you.

Your checklist before November 19

Make the call. Ask every provider who touches your 1099s — payroll, AP/bill pay, bookkeeper, CPA — whose TCC they transmit under and whether their IRIS application is complete. Write down names and dates.
If you transmit your own returns, start the IRIS Application for TCC today. You need your EIN, two Responsible Officials, and two Contacts. The 45-day processing window is why "today" is not dramatic.
Review your existing IR Application before November 9. People leave companies. Addresses change. If the record is wrong, that Monday is your last chance to amend it.
Clear your correction backlog before November 19 at 3:00 p.m. ET. Not end of day. Not your time zone.
Get your vendor data clean while you have breathing room. Every 1099 season breaks on the same thing: missing or stale Form W-9 information. A current W-9 on file for every vendor you paid, with a verified TIN and legal name, is the difference between a one-afternoon filing and a three-week scramble. This is the single highest-return thing you can do in the next month, and it has nothing to do with which system you file in.

That last item is the one we'd push hardest. The platform change is a one-time inconvenience. Vendor-data hygiene is what makes January survivable every year — it's a core part of how we run accounts receivable and payable for clients, and it's usually the first thing we fix when we take over a messy AP function.

Where this lands

For most small businesses, the honest summary is: this is probably a phone call, not a project. Make the call, get a name, and move on.

For the subset who do transmit their own returns, it's a real deadline with a 45-day application sitting in front of it, and the useful move is to start the application this week and treat November 9 as the date that matters.

Either way, it is the kind of thing that should never have reached your desk. If 1099 season has been landing on you — or on an office manager who already has a full job — we can take the vendor file, the W-9s, and the filing off your plate entirely. Our tax and compliance and AP work is built for exactly this, and we work with small businesses who would rather pay the right amount all year than spend a week in January figuring out which IRS system they're supposed to be using.
