What Is Form 1094-C?

Form 1094-C, Transmittal of Employer-Provided Health Insurance Offer and Coverage Information Returns, is an IRS form used by applicable large employers. It transmits Forms 1095-C to the IRS and provides summary information about the employer's health coverage reporting.

The form is part of Affordable Care Act employer reporting. Employees generally receive Form 1095-C, while Form 1094-C is the employer-level transmittal sent to the IRS.

Key Takeaways

  • Form 1094-C is filed by applicable large employer members.
  • It transmits Forms 1095-C to the IRS.
  • It reports summary information used for ACA employer compliance.
  • It is separate from payroll tax returns such as Forms 941 and 944.

How Form 1094-C Works

Applicable large employers use Form 1094-C to report employer-level details, including contact information, the number of Forms 1095-C submitted, and whether the filing is the authoritative transmittal. The authoritative transmittal is the form that reports aggregate employer information for the ALE member.

Form 1094-C helps the IRS process employer-provided health coverage reporting and determine whether employer shared responsibility rules may apply. It works together with Form 1095-C, which reports employee-level offer and coverage information.

Why the Filing Matters

Errors can create IRS notices, employee confusion, or ACA reporting problems. The form depends on accurate workforce counts, coverage-offer records, employee status, and controlled-group analysis when related entities are involved.

The Bottom Line

Form 1094-C is the employer summary and transmittal for ACA Form 1095-C reporting. Its practical value is reconciliation: it tells the IRS how the employer's coverage-reporting package fits together.
