Are You Ready for Real-Time 1099 Compliance? 7 Questions to Ask Before IRIS Takes Over

The transition from the IRS's FIRE system to IRIS represents more than a new way to submit 1099 forms. It reflects a broader shift toward real-time validation, greater emphasis on data quality, and more connected compliance workflows. For many organizations, readiness depends on much more than tax expertise. Finance, IT, operations, procurement, and security must coordinate long before filing season begins. The seven questions below can help you identify where your organization is prepared and where gaps may increase compliance risk as IRIS adoption continues.

As you work through each question, answer Yes if your organization has the capability in place today or No if it does not or you are unsure. At the end of the assessment, you'll see how your responses compare to three levels of IRIS readiness. For a more detailed evaluation, Sovos's 1099 Filing Readiness Score assessment can help you assess readiness across data quality, technology, state filing, correction workflows, and other key areas.

1. Are you validating TINs and names at onboarding or only before filing?

The quality of your 1099 reporting is largely determined long before the first information return is prepared. If taxpayer names and Taxpayer Identification Numbers (TINs) are collected without verification during vendor onboarding, those records can remain in your systems for months before anyone discovers a problem.

Under IRIS, that approach becomes more difficult to sustain. Real-time validation places greater emphasis on submitting accurate information from the start, reducing the opportunity to identify and correct errors at the end of the reporting cycle. A mismatched name and TIN can delay filing, require additional research, or trigger IRS notices that consume valuable time during an already busy reporting season.

A stronger process builds TIN validation into vendor setup rather than leaving it for year-end cleanup. Verifying taxpayer information when a vendor is first added, then periodically revalidating records as needed, helps improve the accuracy of vendor records across the entire reporting lifecycle. Organizations can also use the IRS's TIN Matching Program to verify name and TIN combinations before filing information returns. Earlier validation can also reduce the number of exceptions finance teams must investigate when filing deadlines are approaching.

2. Can your systems split and manage the structured name fields required by IRIS?

Even organizations with accurate taxpayer information may encounter problems if their systems cannot store it in the format IRIS expects. Many accounting, ERP, and procurement platforms were designed around a single name field, while IRIS requires information to be submitted using structured data elements that distinguish businesses from individuals and separate name components where appropriate. 

If your organization uses an automated connection to file with IRIS, confirm with your IT team or filing provider that your systems can produce files that meet current IRS requirements.

For some organizations, this is less of a tax issue than a systems issue. If vendor records are stored inconsistently across multiple applications, transforming that data into the required format can become a manual process that introduces delays and increases the risk of errors.

The first step is determining whether source systems can capture and export the data IRIS requires. Where gaps remain, standardized data practices or integrations can reduce manual corrections before filing.

3. Do you know whether your current TCC is FIRE-specific or IRIS-ready?

The IRS requires separate Transmitter Control Codes (TCCs) for the FIRE and IRIS systems. Organizations that previously filed through FIRE will need to complete the IRIS application for a TCC before they can submit returns through the new platform. An IRIS TCC can only be used within IRIS, so an existing FIRE TCC does not provide access to the system. Waiting until filing season to confirm those credentials can create unnecessary delays, especially if testing or system configuration depends on approved access.

This is also a good opportunity to review who manages filing credentials within your organization. If access is limited to one employee, undocumented, or tied to outdated processes, even a routine transition can become more disruptive than expected.

4. Can your team respond to real-time validation errors during the filing window?

A significant operational change under IRIS is when filing errors are identified. Instead of discovering certain issues after returns have been submitted, organizations may receive validation feedback during the filing process. That shifts compliance from a submit-and-wait model to one that may require immediate action.

Ask yourself what happens if a submission is rejected. Does your team have a documented process for identifying the cause, correcting the underlying record, and resubmitting the return? Is it clear who owns each step, or will your finance team spend valuable time tracking down answers across multiple departments?

A documented workflow should explain how validation messages are reviewed, records are corrected, and returns are resubmitted. Testing that workflow before filing season helps teams respond more efficiently when validation errors occur.

Teams that file through the Taxpayer Portal can consult the IRS's IRIS Taxpayer Portal User Guide for current instructions on submitting returns, reviewing filing activity, and correcting information through the portal.

5. Can you generate both federal IRIS XML filings and state-required formats?

IRIS modernizes federal filing, but it doesn’t eliminate differences in state reporting requirements. Some states continue to use separate formats or filing methods.

That means organizations may need to support multiple output formats from the same set of 1099 data. Depending on the jurisdiction, that could mean generating IRIS XML for federal filing while also producing legacy formats or other state-specific file types required by state agencies. A process that works for federal reporting may still require additional formatting, validation, or file generation to satisfy state requirements. If those capabilities depend on manual workarounds, the risk of delays and inconsistencies increases as filing volumes grow.

Organizations with well-established reporting processes identify their filing obligations well before reporting season and verify that their systems can produce the required outputs for every jurisdiction where they report. Rather than treating federal and state reporting as separate projects, they build workflows that support both from a common source of accurate, well-governed data.

6. Do tax, IT, security, and operations have clear ownership for IRIS readiness?

IRIS readiness is rarely owned by a single department. Tax teams understand reporting requirements, but they often depend on IT to support integrations, security to protect sensitive taxpayer data, procurement to collect vendor information, and operations to ensure business processes are followed consistently. Without clearly defined responsibilities, even minor issues can take longer to resolve.

A useful way to assess readiness is to ask who owns each stage of the process. Who is responsible for validating taxpayer information? Who manages filing credentials and system access? Who investigates validation errors or updates vendor records when problems are identified? If those answers are unclear, your organization may encounter unnecessary issues when reporting deadlines approach. Documented ownership and escalation paths can help teams resolve issues faster while reducing confusion during filing season.

7. Are you treating 1099 compliance as an ongoing workflow or a year-end task?

The answers to the previous questions often point to a larger issue. Organizations that struggle with IRIS readiness are rarely missing just one capability. More often, they are relying on a compliance model that concentrates most of the work into the weeks leading up to filing deadlines.

That approach leaves little time to resolve inaccurate taxpayer information, update filing credentials, address system limitations, or respond to validation errors. As reporting requirements become more automated and data-driven, the cost of postponing those activities continues to increase.

A year-round compliance model provides a stronger foundation for IRIS. Taxpayer information can be validated as it enters the organization, while filing workflows are reviewed well before deadlines approach. This reduces last-minute work and improves filing confidence.
