With the FIRE (Filing Information Returns Electronically) system retiring at the end of 2026. Tax year 2025 returns, filed by December 31, 2026, are the last that can go through FIRE, while tax year 2026 returns, due in the 2027 filing season, must go through the new IRIS (Information Returns Intake System) instead. Businesses should be aware of the new, rigid requirements and regulations.
Here’s What’s New
- Information returns will be electronically filed to the IRS through the IRIS web portal, where structured formatting will be critical. Larger-volume filers (100 or more returns) must submit data as structured XML files through IRIS’s Application-to-Application (A2A) system; smaller filers can enter data manually or upload a CSV file through the IRIS Taxpayer Portal instead.
- Rather than lumping entire name strands into one field, the XML file will mandate a strict separation of first, middle, and last names, and suffixes (such as Jr., Sr., or III), when inserting taxpayer information to ensure cleaner data management.
- The new XML schema includes a separate field to specify the TIN type (SSN, EIN, or ITIN).
- Real-time validation on TIN/Name matching upon submission, rather than delayed CP2100 or CP2100A notices. A TIN mismatch now shows up immediately as an “Accepted with Errors” status on the web portal instead of surfacing weeks or months later.
- The new IRIS web portal automatically tracks and stores on record filed information returns to incentivize employer self-accountability, and allows payers to download copies to be sent off to recipients within the portal system.
The Problems the New IRIS System Poses for Businesses
- Heightened risk of receiving rejections on files prior to the information return deadline, thus increasing the likelihood of late filing penalties if not addressed
Businesses that tend to procrastinate filing information returns run the risk of being subjected to late filing penalties if they fail to identify and address unforeseen errors on near-overdue files. As a result, there is an emerging incentive for businesses’ tax departments to review XML files prior to submission to identify elusive mistakes that may trigger rejections or acceptances with errors, avoiding this unfavorable situation — an excessively time-consuming process that requires thousands of individual 1099 forms to be closely examined.
- Stricter XML schema mandates database and software reworking
Due to the parsing of employee/contractor names and the indication of TIN variation, errors are likely to arise for businesses accustomed to the ASCII format of FIRE, causing staff accountants to be flooded with manual corrections. Moreover, if error detections on submitted information returns repeatedly arise, businesses will be required to extensively modify their database to fit within the framework of the new XML schema and likely rework internal software.
- The easily interpretable format of XML files for the IRS enables more precise monitoring of information return compliance, increasing the frequency of IRS penalty notices and correction requests
As a result of the standardized formatting, the IRS can more easily identify inconsistencies between reported incomes on tax returns and reported payments on information returns, resulting in a higher probability of notices on unresolved returns and penalties for unsubmitted returns. As a result, tax departments are increasingly tasked with responding to said notices and diligently tracking the number of filed returns, in addition to revising rejected files, exacerbating administrative burden. Moreover, the IRS’s overall sensitivity to discrepancies further emphasizes the need for employers to accurately record payments made to contractors/employees and improve data clarity.
