The ACA provision mandates that employers provide their employees with affordable healthcare. In line with this, Sections 6055 and 6056 of the ACA state that Applicable Large Employers (ALEs) must submit 1094-C and 1095-C forms to the IRS by the deadline.

Ultimately, ALEs use the 1094-C and 1095-C forms to report the employee health insurance information offers to the IRS.

What is Form 1094-C?

Form 1094-C serves is the Transmittal of Employer-Sponsored Health Insurance Offer and Coverage Information Returns Form, accompanying Form 1095-C in annual IRS filings.

Form 1094-C is essentially a summary of the 1095-C information returns. This form is only submitted to the IRS and not given to the employees.

What is Form 1095-C?

Form 1095-C is an information return filed by employers with at least 50 full-time + full-time equivalent employees. These employers are known as 'Applicable Large Employers' or ALEs by the IRS. This form tells the IRS if the employer met ACA guidelines for the healthcare coverage they offer, and it requires that employees receive a recipient copy.

What are the types of Form 1095 Penalties?

ACA penalties are typically split into two categories:

  1. Employer Shared Responsibility Payment (ESRP): This penalty applies to large employers who do not offer minimum essential coverage to at least 95% of their full-time employees (and their dependents), and at least one of their full-time employees receives a premium tax credit for purchasing individual coverage on one of the health insurance marketplaces. The ESRP is also known as the "employer mandate" or "play or pay" penalty.

  2. Reporting and Disclosure Penalties: These penalties are assessed for failing to file required information returns with the IRS or to provide required statements to individuals. These information returns include Form 1094-C and Form 1095-C, which large employers must file under the ACA's reporting requirements.
