As organizations prepare for the IRS transition from the FIRE platform to IRIS, the technical impact on 1099 reporting processes becomes impossible to ignore. The shift from the longstanding 1220 flat file to IRIS’s complex XML structure represents more than a new formatting requirement - it fundamentally changes how data must be prepared, validated, transmitted, and corrected.

Join Sovos experts for an in-depth, technical session designed specifically for teams responsible for building, transforming, or transmitting 1099 data. We’ll explore the critical differences between flat file and XML based reporting, break down how real-time IRIS validations reshape submission workflows, and walk through what testing, timelines, and dual format reporting will look like during the transition period.

Key learnings include:

• Dive into the technical differences between the FIRE’s 1220 flat file and IRIS’ XML, including size, complexity, and name field requirements.
• Get clarity on what IRIS testing entails and the timeline organizations should anticipate.
• Gain understanding around what dual format reporting will look like as states continue using FIRE based specifications while federal reporting shifts to IRIS.
