One of the most common types of ACA e-filing errors returned from the IRS AIR system are TIN validation errors, including EIN errors. The most common EIN errors are listed below:
- 1094C-004-01 – Form 1094C ‘BusinessName’ and ‘EmployerEIN’ in ‘EmployerInformationGrp’ must match the IRS database. Form 1094C ‘BusinessName’ and ‘EIN’ within ‘OtherALEMembersGrp’ must match the IRS database.
- 1094C-079-01 – Form 1094C ‘BusinessName’ and ‘EIN’ within ‘OtherALEMembersGrp’ must match the IRS database.
- 1095B-052-01 – Form 1095B ‘BusinessName’ and ‘EIN’ within ‘IssuerInfoGrp’ must match the IRS database.
What causes an EIN Validation Error?
This will happen when the name and TIN submitted in your filing doesn’t match what the IRS has on file, and this can happen for the following reasons:
- An employer EIN mismatch on the 1094-C in Part I and also in Part IV of the 1094-C for Aggregate ALEs. (Note: This can also cause TIN validation errors in the associated 1094-Cs for remaining ALE members.)
- A Issuer Name and EIN mismatch on the 1095-B in Part III, in the Issuer Information section.
