IRIS-native since launch
Zenwork has operated on IRIS since launch and files under its own TCC,
with no separate TCC application required.
High-volume tax reporting requires more control
At high volume, every unresolved record creates more work before, during, and after filing.
Build control into the filing process
Support your team’s filing readiness by collecting W‑9s early and validating TINs, addresses, and source data to resolve data quality issues.
IRIS filing infrastructure is already built In
Zenwork already provides the TCC, form-level status, and centralized correction workflow required for IRIS.
Maintain end-to-end reporting visibility
Close the reporting cycle with support for state filing, furnishing, corrections, and prior-year reporting obligations.
9,000+ forms processed in under 40 hours
“We would spend weeks processing and mailing with numerous individuals involved before. With Tax1099, total filing takes less than 40-man hours now.”
Integrates with existing enterprise workflows
Zenwork connects existing systems, AI agents, and human review workflows without replacing established processes.
Frequently asked questions
When is FIRE being retired for 1099 filing?
FIRE will no longer accept information returns after November 19, 2026. Beginning with tax year 2026 returns filed in 2027, IRIS becomes the IRS intake system for information returns previously filed through FIRE. Zenwork has operated on IRIS since launch.
Can I use my existing FIRE TCC with IRIS?
No. FIRE and IRIS Transmitter Control Codes are not interchangeable. Organizations transmitting directly through IRIS must obtain an IRIS TCC. With Zenwork, customers file under Zenwork’s TCC, so they do not need a separate IRIS TCC application for the Zenwork filing workflow.
What changes when moving from FIRE to IRIS?
IRIS changes more than where information returns are submitted. FIRE used Publication 1220 file specifications, while high-volume IRIS Application-to-Application filing uses XML schemas and an interactive transmission process. IRIS also returns acknowledgement statuses and error information that filing workflows must interpret and act on.
How are errors and corrections handled in IRIS?
IRIS can return different filing outcomes across submitted records. Zenwork tracks filing status at the form level, so teams can identify affected records and correct or refile forms requiring action while other forms continue through the reporting process.
Do 1099s need to be filed with states as well as the IRS?
State information reporting requirements vary by state, form, and filing situation. Reporting may involve Combined Federal/State Filing, direct-state filing, state-only filing, corrections, or reconciliation forms. Zenwork supports federal filing and reporting requirements across all 50 states within the same reporting workflow.
