What's Happening?
The Internal Revenue Service (IRS) is mandating a significant change in how information returns, specifically 1099 forms, are e-filed. Starting with tax year 2026, the new IRIS (Information Returns Intake System) will be the sole method for e-filing,
replacing the long-standing FIRE (Filing Information Returns Electronically) system. The FIRE system will cease accepting submissions on November 19, 2026, and by January 1, 2027, IRIS will handle all current-year, prior-year, and corrected returns. This transition requires organizations to either integrate IRIS filing into their own systems or utilize a third-party provider. The IRS offers two in-house options: the IRIS Taxpayer Portal for low-volume filers (capped at 100 forms per submission) and a direct Application-to-Application (A2A) integration for bulk filers, which requires significant software development and adherence to IRS specifications, including XML generation and secure web service integration.
Why It's Important?
This transition is critical for U.S. businesses and organizations that file 1099 forms, as it necessitates a complete overhaul of their e-filing processes. The shift from the flat-file FIRE system to the XML-based IRIS A2A system means that existing export functionalities will no longer be compatible, requiring substantial IT development for in-house solutions. Organizations must apply for a new IRIS Transmitter Control Code (TCC), as their FIRE TCC will not carry over, and undergo IRS Assurance Testing System (ATS) before transmitting live returns. For many, especially those with high volumes of forms, the complexity and resource demands of building an in-house A2A integration are considerable. The alternative of using a third-party provider offers a way to outsource the technical complexities, annual IRS schema updates, and compliance requirements, allowing businesses to focus on their core operations and avoid the significant development and maintenance costs associated with direct integration.
What's Next?
Organizations must decide whether to build in-house IRIS capabilities or outsource their 1099 e-filing to a provider before the January 1, 2027 deadline. Those opting for in-house A2A integration face a tight timeline, as TCC applications can take up to 45 business days to process, and IRIS A2A testing typically opens in November. This compresses application, development, testing, and go-live into the weeks leading up to year-end and the 2027 filing deadlines. Providers like TAB1099 offer services that handle the conversion of existing data formats (FIRE, CSV, Excel) to IRIS XML, validation against IRS business rules, and transmission under their own TCC. This allows businesses to avoid the complexities of TCC management, system changes, and absorbing annual IRS updates. The choice will depend on an organization's filing volume, IT resources, and desired level of control over the filing process.
Beyond the Headlines
The IRS's move to IRIS reflects a broader governmental push towards modernizing digital infrastructure and enhancing data security and efficiency. The adoption of XML for information returns aligns with contemporary data exchange standards, which can improve data integrity and interoperability. However, this modernization also creates a significant compliance burden for businesses, particularly small and medium-sized enterprises that may lack the IT resources to adapt quickly. The reliance on third-party providers for compliance highlights the growing ecosystem of specialized services that bridge the gap between government mandates and business capabilities. This transition could also influence future IRS initiatives, potentially leading to similar modernizations for other tax forms and reporting requirements, further emphasizing the need for businesses to stay agile and adaptable to evolving digital compliance landscapes.
