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).
What does Form 1095-C include?
Form 1095-C communicates the details of the health insurance coverage startups provide to their employees, including details about the coverage offered, the cost of coverage, the months it was available, and the employee’s enrollment status.
When is Form 1095-C due?
Startups must furnish Form 1095-C to employees by the deadline specified by the IRS, usually around early February, and also submit copies of these forms to the IRS. Startups need to maintain accurate records to ensure the information they report on Form 1095-C is correct, and many use software programs or work with a professional employer organization (PEO) to help manage the process.

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:
Step 1: Confirm Your Startup’s Filing Requirements
Ensure your startup is required to file Form 1095-C:

- You must file Form 1095-C for each full-time employee, even if they did not participate in your health plan.
Step 2: Download Form 1095-C and Instructions
- Visit the IRS website and download the latest version of Form 1095-C and the corresponding Form 1095-C Instructions.

Tips for Filing Form 1095-C
- Use an experienced startup accountant. As you can see from these Form 1095-C instructions, tax forms are complicated. We recommend you work with an experienced startup tax professional.
- Consult a payroll provider. Many payroll services assist with ACA reporting, including generating and filing Forms 1095-C.
- Use safe harbor codes. Properly applying safe harbor codes can protect your startup from penalties.
- Track full-time equivalents (FTEs). If your startup is close to the 50-employee threshold, carefully track FTEs to determine whether you must file Form 1095-C.
