Startups with 50 or more full-time employees, including full-time equivalent employees, use IRS Form 1095-C to report information about the health coverage they offer to their employees.
This form is a key component of the Affordable Care Act (ACA) compliance requirements for applicable large employers (ALEs).
Step-by-step instructions: Form 1095-C
IRS Form 1095-C, Employer-Provided Health Insurance Offer and Coverage, is used by applicable large employers (ALEs), typically with 50 or more full-time employees, to report information about health insurance coverage offered to their employees. Like many tax forms, this form can be complex and we strongly recommend that startups consult a tax professional or CPA. This form is part of the Affordable Care Act (ACA) reporting requirements.
Here are step-by-step Form 1095-C instructions for a startup company to fill out this form:

Your startup is considered an Applicable Large Employer (ALE) if you employed an average of 50 or more full-time employees (or full-time equivalents) during the previous calendar year.
-
You must file Form 1095-C for each full-time employee, even if they did not participate in your health plan.
