Transmitting 1099s Through IRIS: Understanding Access, Credentials, and Reporting Readiness

As IRIS becomes the new and only IRS system for filing information returns (1098s, 1099s, 1042-S, 5498s, etc.), reporting teams must prepare for transmission requirements that look very different from filing with the FIRE system. IRIS introduces two different ways to file information returns depending on volume, along with stricter filing requirements and certifications, more validations during submission, and new filing responses and error messages that filers must navigate at the time of filing.

In this session, Sovos experts will break down the filing requirements that define the IRIS transmission experience and explain how they differ from traditional FIRE workflows.

Key learnings include:

  • Understand IRS mandated submission paths under IRIS – A2A or portal?
  • Learn what’s required to obtain and manage IRIS TCC credentials
  • Challenges organizations can expect when filing via A2A (250+ information returns)
  • Explore the core elements of IRIS readiness and what maintenance looks like going forward
