Transmission Processing Errors in IRS AIR System

Erich Ruth

ACA Compliance

Transmission Processing Errors (TPE) in the IRS Affordable Care Act Information Returns (AIR) system occur when submitted files do not meet specific schema, data, or formatting requirements for electronic filing. These errors can stop your forms from being processed successfully.

For businesses filing ACA forms, understanding TPE errors is critical to avoid rejected submissions and IRS penalties. If you need software that ensures your forms pass IRS checks, explore our ACA 1095 software.

Categories of TPE Errors

TPE errors are grouped into categories that highlight the specific issues:

File Structure Errors – Issues with XML formatting or missing sections.
Schema Validation Errors – Problems with data not matching the XML schema defined by the IRS.
TIN Validation Errors – Invalid or mismatched Taxpayer Identification Numbers. Learn more about avoiding issues with our IRS TIN Matching service.
Duplicate Files – Resubmission of previously processed files.
Business Rule Violations – Content issues that fail IRS validation rules.

I have used 1099 Fire for a number of years to prepare and file 1099 and NEC01 data for our multiple entities and highly recommend this service. It is easy to use, the data can be reviewed prior to sending and they mail the 1099/NEC's directly to the recipients, eliminating that hassle.

We did it again! We have been using 1099Fire to generate our 1094’s and 1095’s since the Affordable Care Act was passed and the filings were required. The customer service is 5 stars! Dan, Amy, and Abby are always very helpful and professional. I would strongly recommend them for all your filing needs.

I'd tried a competitor but have never changed since trying 1099Fire. They PICK UP THE PHONE and help with issues. I've tried both outsourcing to them (ACA reporting) and doing it myself, using their software. I went back to outsourcing, seeing how much time it can take to fix errors, how many complications can arise, and how much the IRS can F__k you for getting this wrong. Highly recommend 1099Fire! Dan and Amy are phenomenal!
