FIRE E-File System Closes Nov. 19 — Q3 Deadlines Collide

The Situation

FIRE stops accepting information returns Nov. 19, 2026, at 3 p.m. ET, the same month Form 941, Form 720, and Form 2290 fall due Nov. 2, 2026 on the IRS fourth-quarter tax calendar. Offices that currently send information returns through FIRE need an IRIS Transmitter Control Code before that cutoff.

The Facts

The IRS confirmed in newsroom release IR-2026-99, dated Aug. 24, 2026, that FIRE stops accepting information returns Nov. 19, 2026, at 3 p.m. ET (irs.gov/newsroom/irs-reminder-information-return-e-file-system-transitioning-to-a-new-platform). Current FIRE users must transition to the Information Returns Intake System, or IRIS, to file tax year 2026 information returns during the 2027 filing season. After the November maintenance window, filers will no longer be able to submit information returns through FIRE.

An IRIS Transmitter Control Code is a five-digit code that identifies the business when it e-files forms and can only be used for IRIS. The free IRIS Taxpayer Portal lets filers e-file up to 100 returns at a time, typed in or uploaded as a CSV. Filers with third-party software or a service can use IRIS Application to Application (A2A) to e-file thousands of returns, up to 100 MB at a time, the IRS IRIS page says. Two earlier deadlines apply. Nov. 9, 2026 is the last day to make changes to an IR Application for a Transmitter Control Code. Nov. 1, 2026 is the last day to file test information returns through the FIRE Trading Partner Test System.

That timeline collides with filings already on the fall calendar. The IRS fourth-quarter tax calendar lists Form 941 for the third quarter, Form 720 for the third quarter, and Form 2290 for any truck first used in September — all due Nov. 2, 2026. How long an IRIS TCC application takes to process remains unconfirmed in IR-2026-99, as does whether a Transmitter Control Code already on file for FIRE carries over to IRIS. Offices already filing information returns through a payroll vendor or a CPA may not need a new application — the only way to know is to ask that vendor or a licensed CPA or EA. This is general information, not tax advice.

Business Impact

A missed TCC application does not show up as a bounced form. After Nov. 19, 2026, at 3 p.m. ET, FIRE will no longer accept information returns. Offices that file information returns for subcontract drivers, part-time help or lease payments are exposed if they file through FIRE themselves; those using a payroll provider may already be covered under that vendor's own TCC. The last day to change an IR Application for a TCC is Nov. 9, 2026, and IR-2026-99 gives no stated processing time. Confirming whether an office needs its own IRIS code, or already has vendor coverage, is a call to the vendor or a licensed CPA or EA — not something this article can decide.

Key Takeaways

• FIRE stops taking information returns on Nov. 19, 2026, at 3 p.m. ET, so any filing plan built around FIRE needs a replacement before that cutoff.
• The Nov. 9, 2026 deadline to change a TCC application falls before the FIRE shutdown, so waiting until the last week leaves no window to fix a rejected application.
• Form 941, Form 720 and Form 2290 for September trucks are all due Nov. 2, 2026, the same week the FIRE transition deadlines start landing — plan the two together.
• Offices using a payroll vendor or CPA for information-return filing should confirm coverage with that vendor or a licensed CPA or EA rather than assume.

Action Steps

1. 1.Check whether the office files information returns directly through FIRE or through a payroll vendor or CPA before assuming a new IRIS application is needed.
2. 2.If the office files directly, start the IRIS Application for a Transmitter Control Code now — IR-2026-99 gives no stated processing time and the change window closes Nov. 9, 2026.
3. 3.Put Nov. 2, 2026 and Nov. 19, 2026 on the same calendar page as Form 941, 720 and 2290 deadlines so the two are not treated as separate problems.
4. 4.Ask the payroll processor or CPA before the Nov. 9, 2026 change-window close — 10 days before FIRE's Nov. 19, 2026, 3 p.m. ET cutoff: do you file our information returns through FIRE, and if so, are you handling the move to IRIS? This is general information, not tax advice — confirm the specific situation with a licensed CPA or EA.

Competitive Advantage

Confirming our 1099 filing path before mid-October avoids a scramble in January, when payroll vendors and CPAs are buried in year-end work. Knowing today whether we need our own IRIS Transmitter Control Code, or already have vendor coverage, turns a hard deadline into a five-minute call now.
