IRIS Vs FIRE: Which Is Better For Your Small Business 1099 Reporting?

Hey there, it’s Richard Terry, President and CEO of TIG Tax Pros. We are currently sitting in the heart of the 2026 tax season. If you are a small business owner, you know exactly what that means: it is time to get those 1099s out the door.

For years, the IRS has relied on a system called FIRE to handle electronic filings. But things have changed. The IRS recently introduced IRIS, a modern platform designed to make reporting easier. With the current shifts in federal tax law, choosing the right system is no longer just a matter of preference, it is a matter of compliance and efficiency.

If you’re feeling overwhelmed by the alphabet soup of IRS portals, don’t worry. We’re going to break down the differences between IRIS and FIRE so you can decide which path to take for your 2025 tax year filings and beyond.

What is the IRS FIRE System?

FIRE stands for Filing Information Returns Electronically. It has been the industry standard for decades. If you have been filing 1099s electronically for the last ten or twenty years, this is likely the system you have used.

FIRE was built on legacy mainframe technology. It requires users to upload files in a specific ASCII format. For most small business owners, this format is impossible to create manually. You typically need specialized accounting software or a tax professional to generate the complex data files required for a FIRE submission.

Pros of FIRE

• Reliability: It is a proven system that has handled millions of returns.
• High Volume: It is built to handle massive batches of data, making it a favorite for large corporations and high-volume tax practices.

Cons of FIRE

• Outdated Format: The ASCII format is rigid and difficult to troubleshoot.
• Delayed Feedback: When you upload a file to FIRE, you often have to wait days to find out if the file was accepted or if there were errors.
• End of Life: The IRS has officially announced that FIRE is being phased out. As of 2027, it will no longer be available for new filings.

What is the IRS IRIS System?

IRIS, or the Information Returns Intake System, is the IRS’s new, modern answer to the aging FIRE platform. Launched to provide a more user-friendly experience, IRIS is designed specifically with small businesses in mind.

Unlike FIRE, IRIS uses XML format, the same modern data standard used for most other IRS electronic filing systems. More importantly, IRIS offers a web-based portal where you can manually enter data. This is a game-changer for businesses that only have a handful of contractors to report.

Pros of IRIS

• Manual Entry Portal: If you are filing fewer than 100 forms, you can type the information directly into the website. No special software is required.
• Real-Time Validation: IRIS checks for errors as you go. If a ZIP code is missing or a Taxpayer Identification Number (TIN) is formatted incorrectly, the system tells you immediately.
• Enhanced Security: IRIS requires authentication through ID.me, providing a higher level of security than the old FIRE login system.
• Free to Use: There are no filing fees to use the IRS portal directly.

Cons of IRIS

• Newer Infrastructure: While more modern, some users have experienced learning curves with the new interface.
• New Credentials Needed: Even if you have a Transmitter Control Code (TCC) for FIRE, you must apply for a brand-new TCC specifically for IRIS.

Side-By-Side: IRIS vs FIRE

When comparing these two systems, the choice usually comes down to your technical capabilities and the volume of forms you need to file.

The 2026 Filing Reality: Why the Clock is Ticking

As of today, February 27, 2026, we are in a transition period. If you are currently filing your 2025 tax year returns, you still have the option to use FIRE. However, this is essentially the "final call" for the legacy system.

The IRS has mandated that starting in January 2027 (for the 2026 tax year), FIRE will no longer accept new filings. This means that if you haven't switched to IRIS yet, this is the year to do it. Waiting until the last minute next year could lead to processing delays or software compatibility issues.

Furthermore, remember that the threshold for mandatory electronic filing has dropped significantly over the last few years. If you have 10 or more information returns to file, you must file electronically. You can no longer rely on paper forms for these volumes.

How to Get Started with IRIS

If you’ve decided to move to IRIS (which we highly recommend), you need to take a few proactive steps. You cannot simply log in with your old credentials.

1. Set Up ID.me: IRIS requires a verified ID.me account. If you already use ID.me for your personal taxes or Social Security, you are halfway there.
2. Apply for a New TCC: You need an IRIS-specific Transmitter Control Code. Unlike FIRE codes, which are numeric, IRIS TCCs typically start with the letter 'D'. This application can take up to 45 days to process, so do not wait until the filing deadline.
3. Choose Your Method: Decide if you will use the "Taxpayer Portal" for manual entry or the "Bulk Upload" for XML files generated by your software.

Recommendations for Small Business Owners

If you are a small business owner handling your own reporting, IRIS is the clear winner. The ability to manually type in your 1099-NEC or 1099-MISC information without buying expensive third-party software is a massive benefit. The real-time error checking also ensures that you won't receive a "Notice of Penalty" months later because of a simple typo.

For those who use accounting software like QuickBooks or Xero, check your settings. Most modern platforms have already transitioned to IRIS-compatible XML exports. If your software still only produces FIRE-formatted files, it is time to look for an upgrade or a new provider.

Recommendations for Tax Professionals

For my fellow tax pros, the transition is more about workflow. While FIRE might feel comfortable, IRIS provides better data integrity. The move to XML allows for more granular data: for example, separate fields for first and last names, which reduces matching errors at the IRS level.

If you are managing hundreds of clients, you should be moving your bulk filing processes to the IRIS Application-to-Application (A2A) channel. This allows your software to communicate directly with the IRS servers, bypassing the manual upload process entirely.

Final Thoughts from TIG Tax Pros

At TIG Tax Pros, we believe in staying ahead of the curve. The shift from FIRE to IRIS isn't just a technical change; it’s a move toward a more transparent and efficient tax ecosystem.

For the current 2026 season:

• Use IRIS if you want a modern, faster experience with immediate feedback.
• Use FIRE only if you are already set up for it and aren't ready to change your workflow until the 2027 deadline.

Regardless of which system you choose, the most important thing is accuracy and timeliness. Missing the 1099-NEC deadline (which was January 31st) or the general 1099 deadline can result in significant penalties per form.

If you have questions about federal and state tax law changes or need help navigating the IRIS portal, don't hesitate to reach out. We’re here to make sure your small business stays compliant and your stress levels stay low.
