What Is the IRS IRIS System?

The IRS IRIS (Information Returns Intake System) is a free electronic filing platform introduced by the IRS as a modern replacement for the legacy FIRE (Filing Information Returns Electronically) system. IRIS allows filers to submit information returns such as 1099-MISC, 1099-NEC, 1099-INT, and 1099-DIV through a secure, web-based interface.

Unlike the FIRE system, which requires specialized file formatting and a Transmitter Control Code (TCC), IRIS provides an intuitive online portal where filers can manually enter return data, upload CSV files, or submit through an API. This makes it accessible to businesses of all sizes — from sole proprietors filing a handful of 1099 forms to large organizations submitting thousands of returns.

IRS IRIS vs. FIRE System: Key Differences

The IRS has been transitioning from the FIRE system to IRIS as the primary platform for information return e-filing. Understanding the differences is essential for staying compliant:

• Free to use: IRIS is entirely free, while many third-party FIRE-compatible solutions charge per filing.
• Web-based interface: IRIS offers a browser-based portal for direct data entry, eliminating the need for fixed-width file formatting required by FIRE.
• CSV upload support: Businesses can upload information returns via CSV files, making bulk filing more accessible without specialized software.
• API integration: IRIS provides an Application-to-Application (A2A) channel for automated filing, ideal for software developers and large-scale filers.
• Broader form support: IRIS supports a growing number of information return types, and the IRS continues to expand the forms available on the platform.
• Modern authentication: IRIS uses IRS-approved identity verification, whereas the FIRE system relies on TCC credentials.

Who Needs to Use IRS IRIS?

Beginning with tax year 2025, the IRS requires businesses that file 10 or more information returns to e-file electronically. The IRIS platform is one of the approved methods for meeting this requirement. You may need IRIS if you file any of the following:

• Form 1099-MISC — Miscellaneous income, rents, royalties
• Form 1099-NEC — Nonemployee compensation
• Form 1099-INT — Interest income
• Form 1099-DIV — Dividends and distributions
• Form 1099-Q — Payments from qualified education programs
• Form 1099-SA — Distributions from HSAs or MSAs
• Form 1099-PATR — Taxable distributions from cooperatives

Even if you file fewer than 10 returns, the IRS encourages electronic filing through IRIS for faster processing and fewer errors. If you're also required to file ACA forms like the 1095-B or 1095-C, those are submitted through a separate system called the ACA Information Returns (AIR) program.

How to Register for IRS IRIS

Before you can file through IRIS, you must complete a registration process. Here's how to get started:

1. Create an IRS account: Visit the IRS IRIS portal and create an account using your Employer Identification Number (EIN). You will need to verify your identity through the IRS-approved identity verification process.
2. Apply for a Transmitter Control Code (TCC): Even though IRIS simplifies filing, you still need a TCC. Submit your application through the IRS e-Services portal and allow several weeks for processing.
3. Choose your filing method: IRIS supports three filing channels:
   • Taxpayer Portal — Manually key in return data through the web interface. Best for small filers.
   • CSV Upload — Prepare returns in a CSV file and upload in bulk. Ideal for mid-size businesses.
   • A2A (API) — Integrate directly with the IRIS API for automated, high-volume filing.
4. Verify your TIN data: Before filing, ensure all recipient Taxpayer Identification Numbers (TINs) are accurate. Use TIN matching services to validate SSNs and EINs against IRS records and avoid penalties for incorrect information.

The Legacy FIRE System and the Mandatory Transition to IRIS

For over two decades, the FIRE (Filing Information Returns Electronically) system was the IRS's primary platform for electronically submitting information returns like 1099-MISC, 1099-NEC, 1099-INT, 1099-OID, and dozens of other form types. While FIRE served its purpose, it was built on aging technology that presented significant limitations for modern filers.

Why Is the IRS Retiring FIRE?

The FIRE system required filers to prepare submissions in a rigid, fixed-width text format that followed strict IRS Publication 1220 specifications. This meant businesses either needed specialized software or had to rely on third-party transmitters to format and submit their data. There was no web-based data entry option — every filing had to be uploaded as a properly formatted flat file.

Additional limitations of the FIRE system include:

• Complex file formatting: Fixed-width ASCII text files with strict field positions, making manual preparation error-prone and impractical.
• No browser-based entry: Unlike IRIS, there was no option to key in individual returns through a web portal.
• Outdated authentication: FIRE relied on Transmitter Control Codes (TCCs) and legacy login credentials that did not meet modern security standards.
• Limited error feedback: Filers often had to wait for batch processing results to discover rejected records, slowing down the correction cycle.
• No API access: FIRE had no application-to-application integration, requiring manual file uploads for every submission.

The FIRE to IRIS Transition Timeline

The IRS introduced IRIS in 2023 as a modern alternative to FIRE, initially supporting a limited set of 1099 form types. Over subsequent filing seasons, the IRS expanded IRIS capabilities and encouraged filers to begin transitioning.

After tax year 2025, the FIRE system will no longer accept information return filings. This means that for tax year 2025 returns — filed during the 2026 filing season — and all future tax years, businesses must use IRIS or an IRS-approved third-party transmitter like BoomTax to electronically submit 1099 forms and other information returns to the IRS.

What You Need to Do Now

If your business previously filed through the FIRE system, you should take the following steps to prepare for the mandatory switch:

1. Register for IRIS immediately: Don't wait until the filing deadline. The TCC application and identity verification process can take several weeks, so start now to avoid delays.
2. Update your filing workflow: If you used software that generated FIRE-formatted files, confirm that your provider supports IRIS — either through CSV upload or A2A API integration. BoomTax already supports IRIS-compliant filing.
3. Verify recipient data: Use TIN matching to validate all recipient Taxpayer Identification Numbers before your first IRIS submission. IRIS validates TIN data at submission, and mismatches will result in rejected returns or IRS penalty notices.
4. Test with a small batch: Submit a small number of returns through the IRIS Taxpayer Portal first to familiarize yourself with the interface before uploading your full filing.
5. Plan for deadlines: The transition may introduce a learning curve. Give yourself extra time during your first IRIS filing season so you're not rushing to meet the Tuesday, March 31^st, 2026 e-file deadline.

The retirement of FIRE is not optional — businesses that fail to transition risk being unable to file on time, which can trigger penalties ranging from $60 to $340 per form. If you need help navigating the switch, BoomTax provides a guided filing experience that handles IRIS submission on your behalf.

Still Using Publication 1220 Files? BoomTax Makes the Switch Easy

If your organization has been filing information returns through the FIRE system, chances are your payroll software, accounting platform, or in-house tools generate files formatted to IRS Publication 1220 specifications — the fixed-width ASCII text format that FIRE required for decades. With FIRE being retired after tax year 2025, many businesses are facing a difficult question: what do we do with our existing 1220 files?

Rebuilding your data pipeline from scratch to produce IRIS-compatible CSV or API payloads is expensive and time-consuming. That's where BoomTax steps in.

Drag-and-Drop 1220 Import with Automatic IRIS Conversion

BoomTax supports legacy Publication 1220 file imports as a simple drag-and-drop workflow. Instead of reformatting your data or switching software, you can take the same 1220 file your system already produces and upload it directly into BoomTax. The platform automatically parses the fixed-width records, validates the data, and transforms it into the format required for IRIS submission — no manual conversion needed.

Here's how it works:

1. Export your 1220 file: Generate your Publication 1220 formatted file from your existing payroll or accounting software — the same file you would have uploaded to FIRE.
2. Drag and drop into BoomTax: Log in to BoomTax and drag your 1220 file directly into the import area. BoomTax reads all payer, recipient, and amount records from the file automatically.
3. Review and validate: BoomTax runs TIN verification, checks for formatting errors, flags missing data, and highlights any records that need attention before filing.
4. Submit to the IRS: Once validated, BoomTax handles the IRIS submission on your behalf — converting your legacy data into the correct format, transmitting it to the IRS, and returning filing confirmations for your records.

Why This Matters for 1220 Filers

Many businesses — especially payroll service bureaus, financial institutions, and large employers — have invested years into building automated workflows that produce Publication 1220 files. The transition to IRIS doesn't have to mean scrapping that investment. With BoomTax's 1220 import capability, you can:

• Keep your existing software: No need to replace or reconfigure your payroll or accounting platform. If it exports a 1220 file, BoomTax can use it.
• Eliminate manual data entry: Skip the tedious process of re-keying records into the IRIS Taxpayer Portal or reformatting into CSV templates.
• Reduce conversion errors: Automated parsing means no accidental field shifts, truncated TINs, or misaligned dollar amounts that come with manual reformatting.
• File all supported 1099 types: BoomTax supports importing 1220 records for 1099-MISC, 1099-NEC, 1099-INT, 1099-DIV, and other information return types.
• Handle corrections seamlessly: If a filing needs to be corrected, BoomTax manages the correction submission through IRIS without requiring you to generate a new 1220 file.

Whether you're filing ten 1099 forms or ten thousand, BoomTax bridges the gap between your legacy 1220 workflow and the new IRIS filing requirement — so you can meet every deadline without overhauling your entire process.

Important IRIS Filing Deadlines for 2026

Meeting IRS filing deadlines is critical to avoiding penalties. The following deadlines apply to information returns filed through IRIS for tax year 2025:

Recipient Copy Deadline: Monday, February 2^nd, 2026
You must furnish copies of all information returns to recipients by this date.

IRS E-File Deadline: Tuesday, March 31^st, 2026
This is the deadline for electronically filing information returns with the IRS through IRIS.

1099-NEC Deadline: Monday, February 2^nd, 2026
Form 1099-NEC has an earlier deadline than other 1099 forms. Both the recipient copy and IRS filing are due on the same date.

If you need additional time, you can request a 30-day extension by submitting Form 8809 through IRIS or via BoomTax's extension filing tool. Note that extensions apply only to the IRS filing deadline — the recipient copy deadline cannot be extended.

Filing Corrections Through IRIS

If you discover errors after submitting information returns, IRIS allows you to file corrected returns electronically. Common corrections include:

• Incorrect dollar amounts
• Wrong recipient TIN or name
• Incorrect form type filed
• Missing or inaccurate payer information

Filing corrections promptly helps you avoid escalating IRS penalties and ensures your records are accurate for both you and the recipient.

Penalties for Late or Incorrect IRIS Filings

The IRS imposes penalties for failure to file information returns on time, whether you file through IRIS, the FIRE system, or any other method. For tax year 2025, the penalty amounts are:

• $60 per form if filed within 30 days of the due date (maximum $683,000).
• $130 per form if filed more than 30 days late but by August 1 (maximum $2,049,000).
• $340 per form if filed after August 1 or not filed at all (maximum $4,098,500).
• $680 per form for intentional disregard of filing requirements (no maximum).

Small businesses with gross receipts of $5 million or less qualify for reduced maximum penalties: $239,000 (within 30 days), $683,000 (by August 1), and $1,366,000 (after August 1).
