If you’ve ever received a tax form labeled 1095-C, you might have wondered what it means and whether it affects your tax return. For employers, it’s a critical compliance document under the Affordable Care Act (ACA). For employees, it’s a record of health insurance coverage that can impact eligibility for tax credits. This guide breaks down everything you need to know about this form, what it is, who gets it, and why it matters.
What Is Form 1095-C?
Form 1095-C, officially titled “Employer-Provided Health Insurance Offer and Coverage,” is an IRS tax form used by Applicable Large Employers (ALEs)—those with 50 or more full-time employees or full-time equivalents. It reports information about the health insurance coverage offered to employees throughout the year.
This form is part of the ACA’s employer mandate, which requires large employers to offer affordable health insurance that meets minimum essential coverage standards or face potential penalties.
Who Receives Form 1095-C?
You’ll receive this form if:
- You worked full-time (30+ hours/week) for an ALE for at least one month during the tax year.
- You were offered employer-sponsored health coverage, even if you declined it.
- You were enrolled in a self-insured health plan, even as a part-time employee or retiree.
Employers must furnish this form to employees by early March (typically March 2 or 3) and file it with the IRS by February 28 (paper) or March 31 (electronic).
What Information Does Form 1095-C Include?
Form 1095-C is divided into three parts:
1. Employee and Employer Information
- Employee’s name, address, and Social Security Number
- Employer’s name, address, and Employer Identification Number (EIN)
2. Offer of Coverage
- Details about the health insurance offered
- Lowest-cost monthly premium for self-only coverage
- Codes indicating the type of coverage and whether it met ACA standards
3. Covered Individuals (for self-insured plans only)
- Names, SSNs, and birthdates of covered individuals (e.g., spouse, dependents)
- Months each person had coverage
Why Is Form Important?
For Employees:
- Not required to file taxes: You don’t need to attach Form 1095-C to your tax return, but you should keep it for your records.
- Proof of coverage: It helps verify whether you had qualifying health coverage, which can affect your eligibility for the Premium Tax Credit if you used the Health Insurance Marketplace.
- Dispute resolution: If the IRS questions your coverage, this form can help resolve discrepancies.
For Employers:
- ACA compliance: Filing Form 1095-C demonstrates that you offered affordable, minimum essential coverage.
- Avoid penalties: Failure to file or furnish accurate forms can result in penalties of $310 per form, up to $3.8 million annually.
Common Mistakes to Avoid
- Missing deadlines: Late filing can trigger automatic penalties.
- Incorrect codes: The IRS uses specific codes to interpret coverage offers. Misreporting can lead to audits or fines.
- Incomplete employee data: Missing SSNs or incorrect addresses can invalidate the form.
How to File Form 1095-C
Employers must also file Form 1094-C, which acts as a cover sheet summarizing all 1095-Cs submitted. Filing can be done:
- Manually (if fewer than 10 forms total)
- Electronically (mandatory for 10+ forms)
Many employers use payroll or benefits administration software to streamline this process and ensure compliance.
