The basics

What is IRS IRIS?

IRIS (Information Returns Intake System) is the IRS's modern platform for electronic information-return filing, replacing the legacy FIRE system. Launched in 2022, it processes all 1099-series forms and accepts submissions through three channels.

The deadline

Why FIRE is ending

FIRE has filed information returns since the early 1990s using fixed-width text files. Its aging architecture can't support modernization — IRIS brings XML submissions, real-time validation, and a modern API. After December 31, 2026, FIRE accepts nothing. Period.

Now
IRIS accepts all 1099 forms via A2A. FIRE and IRIS run in parallel.
2026
IRIS expands to remaining form types. Last year to file through FIRE.
Dec 31, 2026
FIRE shuts down permanently. No exceptions.
Jan 2027+
IRIS is the sole electronic filing channel for information returns.
5 steps

How to migrate from FIRE to IRIS

1Step 1
Audit your current FIRE usage

Identify every system, process, and vendor that touches FIRE so nothing is missed in the move.

2Step 2
Choose your migration path

File through the IRS portal (small volume), build native IRIS XML (developer-heavy), or use a provider like e1099f (zero changes).

3Step 3
Register for IRIS & get a TCC

If filing directly, register and obtain an IRIS TCC. Allow 45+ days for approval. e1099f customers skip this step.

4Step 4
Test your submissions

Use the IRIS testing sandbox to validate your XML before going live. Catch errors before they count.

5Step 5
Go live

Submit your first production filing through IRIS, monitor for error codes, and verify acceptance.

For developers

Technical changes: FIRE vs IRIS

The migration changes how returns are structured, validated, and transmitted. FIRE's position-based flat file becomes IRIS's self-describing XML.

Questions

Frequently asked questions

When does the IRS FIRE system shut down?

FIRE shuts down permanently on December 31, 2026. After that date no submissions are accepted through FIRE; all filing must go through IRIS starting January 1, 2027.

Do I need a new TCC for IRIS?

Yes, if you file directly — FIRE TCCs won't work with IRIS, and the new application takes 45+ days. If you file through an IRS-authorized provider like e1099f, you don't need your own TCC at all.

Can I still use my FIRE-format files after FIRE shuts down?

Not directly with the IRS — IRIS requires XML. But e1099f accepts your existing FIRE-format files and converts them to IRIS XML automatically; your process doesn't change, only the backend filing channel.

How long does IRIS TCC approval take?

The suitability review typically takes 45 days or longer. Including e-Services setup and ID.me, the total can run 2–3 months — so apply well before the FIRE shutdown.
