IRS IRIS Filing — E-File 1099s Through the IRS IRIS System
The IRS Information Returns Intake System (IRIS) is the modern, web-based platform the IRS built to replace the legacy FIRE system for filing information returns. Thomas Ledger integrates directly with IRIS so you can prepare, validate, and transmit your 1099 forms to the IRS without leaving our platform.
What Is IRS IRIS?
IRIS is the IRS's next-generation electronic filing portal for information returns, including all 1099 form types. Launched to replace the aging Filing Information Returns Electronically (FIRE) system, IRIS offers a faster, more reliable, and more secure way to submit tax information returns to the IRS.
Unlike FIRE, which relied on flat-file uploads and outdated protocols, IRIS uses modern APIs and web-based interfaces. This means fewer formatting errors, faster acknowledgments, and a smoother filing experience overall. For a deeper look at the transition, see our guide on What Is IRS IRIS?
How IRIS Replaces the FIRE System
The FIRE system served as the IRS's electronic filing gateway for decades, but it came with significant limitations: rigid file formatting, slow processing times, and frequent downtime during peak filing season. The IRS began phasing out FIRE and transitioning filers to IRIS starting in 2023.
- Modern API architecture — IRIS uses RESTful APIs instead of fixed-width flat files, reducing formatting errors dramatically.
- Faster acknowledgments — Receive filing status confirmations in minutes rather than hours or days.
- Improved error reporting — IRIS provides detailed, actionable error messages so you can correct issues and refile quickly.
- Year-round availability — Unlike FIRE's seasonal shutdowns, IRIS is available year-round for filing and corrections.
Benefits of Filing Through IRIS
Speed and Reliability
IRIS processes filings faster than FIRE ever did. Transmissions are acknowledged within minutes, and the system handles peak-season volume without the outages that plagued FIRE. This means fewer delays and less anxiety during the January filing rush.
Better Error Handling
When IRIS detects an issue with your filing, it returns specific error codes and human-readable descriptions. You know exactly which record has a problem and what needs to be fixed — no more guessing from cryptic FIRE rejection codes.
Enhanced Security
IRIS uses modern encryption and authentication protocols to protect taxpayer data during transmission. Combined with our own enterprise-grade security measures, your data is protected at every step.
Support for All 1099 Types
IRIS accepts all common 1099 form types, including 1099-NEC, 1099-MISC, 1099-INT, 1099-DIV, 1099-K, and more.
How Thomas Ledger Integrates with IRIS
You never have to interact with the IRIS portal directly. Our platform handles the entire transmission process behind the scenes:
- Prepare your forms — Enter data manually, import via CSV, or connect your accounting software. See our bulk filing tools for high-volume options.
- Validate and review — Our system checks every field against IRS requirements before submission, catching TIN mismatches, missing data, and formatting issues.
- Transmit to IRS via IRIS — With one click, we package your forms and send them through the IRIS API. No file formatting, no manual uploads.
- Track status — Monitor your filing status in real time. Receive confirmation when the IRS accepts your returns, or immediate notification if corrections are needed.
- File corrections — If you need to amend a return, do it directly in Thomas Ledger and we retransmit through IRIS automatically.
