Reporting by Large Employers


Employers with 50 or more full-time employees, including full-time equivalent employees, use transmittal Form 1094-C and information return Form 1095-C to report the information required under the Affordable Care Act about offers of health coverage and enrollment in health coverage for their employees. In addition to reporting the coverage that they offer, applicable large employers who sponsor self-insured group health plans will use Forms 1094-C and 1095-C to report information about the coverage they provide to the covered individuals.

Small employers with fewer than 50 full-time employees are exempt from some of the reporting requirements, but not all. Small employers must provide the following:

  • Complete and file Forms 1094-B and 1095-B with the IRS.
  • Provide full-time employees with a copy of Form 1095-B.
  • File Forms 1094-C and 1095-C if they are members of a controlled or affiliated service group that collectively has at least 50 full-time employees.

  • The months in which the employer offered coverage.
  • The employee’s share of the monthly premium for self-only coverage (in certain cases).
