What is Form 1095-C?

IRS Form 1095-C is a form that employers use to report to the ACA the type of coverage that was offered to full-time employees for the previous calendar year. The information that this form carries includes:

• What type of coverage was offered
• What months this coverage was offered
• If this coverage met the ACA requirements for affordability and minimum value

This form helps employees to know that they had coverage for the previous year. It helps employers avoid fines for not being in compliance with the ACA. Essentially, this form enables you to maintain a clean record of your company’s employee benefits.

Who Must File Form 1095-C?

Not all employers are required to submit the Form 1095-C. Only those who are considered Applicable Large Employers (ALEs), which are those employers who employ 50 or more full-time employees, including full-time equivalents, are required to submit the Form 1095-C.

If you are a smaller employer, you do not have to submit the 1095-C form unless you offer voluntary ACA-compliant coverage to your employees. Knowing who is required to submit the Form 1095-C and the reason why they are required to do so is important so that your business is in compliance without unnecessary burden.

If you fail to comply with the regulations, there are penalties that could be enforced against you through the IRS’s regulations on employer shared responsibility, which would force you to provide the employees with the coverage, leading to possible penalties if you fail to do so. This is important so that employers are providing the documentation their employees need to claim their tax benefits related to health coverage.

Understanding 1095-C Reporting Requirements

The 1095-C reporting requirements are geared towards ensuring that you have all the information needed regarding the employer-provided health plans. As part of your ACA reporting requirements, you should:

1. Indicate which employees received the offer of coverage 
2. Support the type of coverage and the months it was available 
3. Use the right IRS codes to indicate the type of coverage, affordability, and eligibility of employees 
4. Fulfill the deadlines set by the IRS and employees

By following all of these requirements, you can maintain 1095-C compliance in 2026, thus avoiding mistakes that could lead to fines and IRS audits.
