Understanding 1095-C Forms: Employer-Provided Health Coverage Explained

When tax season rolls around, many employees receive a document titled Form 1095-C in their mailbox or online portal. It’s one of the key tax forms related to healthcare coverage and compliance with the Affordable Care Act (ACA). The 1095-C forms are issued by employers to inform employees about the health coverage they were offered and whether that coverage met ACA standards.

This guide will help you understand everything about Form 1095-C, including who gets it, what it includes, and how to use it when filing your taxes.


What Is Form 1095-C?

Form 1095-C is a tax document that shows the health insurance your employer offered you during the year. Large employers must send this form to full-time employees, and it includes details about your coverage options, costs, and ACA compliance. Even though you don’t file it with your tax return, it’s important to understand what it means and how to use it.

Form 1095-C acts as proof that your employer offered you health insurance and indicates whether you chose to participate in it. The IRS uses this information to verify employer compliance with ACA regulations and to determine your eligibility for premium tax credits through the Health Insurance Marketplace.


Who Receives the 1095-C Form?

Not everyone receives a 1095-C form. It is specifically for employees of Applicable Large Employers (ALEs)  businesses with 50 or more full-time or full-time equivalent employees.

You will receive the 1095-C tax form if:

  • You were a full-time employee at an ALE for one or more months during the tax year.
  • You were offered employer-sponsored health insurance coverage.
  • You enrolled in or declined the coverage provided by your employer.

Part-time employees typically do not receive a form 1095-C, unless they participated in a self-insured plan offered by the company.


Why Are 1095-C Forms Important?

Although you don’t need to attach the 1095-C tax form to your federal tax return, it serves as an important reference document. The IRS uses it to confirm that large employers are meeting ACA requirements and that employees are receiving access to affordable health coverage.

Key Benefits of the 1095-C Form

  • Proof of offer of coverage: Confirms your employer’s compliance with the ACA.
  • Tax record: Verifies your eligibility for premium tax credits or exemptions.
  • Transparency: Helps employees understand their health benefits and costs.
  • State compliance: Some states require submission of health coverage proof when filing taxes.

Even though you may not file it, keep your 1095-c form with your tax records for at least three years.


What Information Does the 1095-C Form Contain?

The 1095-C forms include several sections with detailed information about your employer, coverage options, and your eligibility for health benefits. Understanding each section will help you verify accuracy and avoid confusion.

1. Part I – Employee and Employer Information

This section lists your name, address, and Social Security Number, as well as your employer’s name, address, and Employer Identification Number (EIN).

2. Part II – Employee Offer and Coverage

This section is crucial. It shows:

  • The type of health insurance offered
  • The lowest-cost monthly premium available to you
  • The months the offer applied
  • ACA codes on Form 1095-C that indicate specific details about your coverage or eligibility

For example:

  • Code 1A means you were offered a qualifying plan at an affordable cost.
  • Code 1E indicates that family members were also eligible for coverage.
    These codes on Form 1095-C are used by the IRS to evaluate employer compliance and individual coverage eligibility.

3. Part III – Covered Individuals

This section appears only if the employer offers a self-insured health plan. It lists the individuals (employees and dependents) who had coverage, along with the specific months they were insured.


Understanding the Codes on Form 1095-C

One of the most confusing parts of the 1095-C tax form is the set of codes used to describe your health coverage. These codes appear in Line 14 and Line 16 and are used by the IRS to verify compliance.



Common Line 14 Coverage Codes:

  • 1A: Employer offered affordable minimum essential coverage
  • 1E: Employee and dependents were offered coverage
  • 1H: No coverage was offered

Common Line 16 Safe Harbor Codes:

  • 2A: Employee not employed that month
  • 2C: Employee enrolled in offered coverage
  • 2D: Employee in a waiting period

Understanding these codes helps ensure the information on your Form 1095-C is correct. If you spot any errors, contact your employer’s HR or benefits department for a correction.


How Form 1095-C Form Affects Your Tax Filing

Although you don’t file the 1095-c form with your tax return, you should use it as a reference when preparing your taxes, especially if you purchased health insurance through the Marketplace.

Step 1: Review for Accuracy

Check your personal details, employer information, and codes. Make sure all data aligns with your records.

Step 2: Keep It for Your Records

Store your 1095-c tax form with other important tax documents in case the IRS requests it later.

Step 3: Use It for State Filings

If your state mandates proof of health coverage (e.g., California, Massachusetts, or New Jersey), you may need to refer to your form 1095-c when filing your state return.


Difference Between 1095-A, 1095-B, and 1095-C Forms

Many taxpayers confuse the 1095-C forms with other ACA-related forms. Here’s how they differ:

FormIssued ByPurpose
1095-AHealth Insurance MarketplaceFor individuals enrolled in Marketplace plans
1095-BInsurers and small employersProof of minimum essential coverage
1095-CLarge employers (50+ employees)Details on employer-provided coverage offers

If you changed jobs or coverage types during the year, you might receive multiple forms.


Common Issues with Form 1095-C and How to Resolve Them

1. Missing Form

If you didn’t receive your 1095 c form, contact your employer’s HR or payroll department. Employers must distribute these by early March each year.

2. Incorrect Information

If your name, coverage details, or months of eligibility are wrong, request a corrected 1095-c form.

3. Misunderstanding Codes

If the codes on form 1095 c confuse you, refer to IRS instructions or consult a tax professional for clarification.


Frequently Asked Questions (FAQs)

1. Do I file my 1095-C form with my taxes?

No, it’s for your records only. However, keep it in case the IRS needs verification.

2. When will I receive my 1095-C tax form?

Employers are required to send the form 1095 c by early March of the following tax year.

3. What if I worked part of the year?

You’ll still receive the 1095-c form if you were a full-time employee for one or more months.

4. Why are there codes on the form?

These codes explain whether coverage was offered, declined, or unavailable, helping the IRS confirm ACA compliance.

5. What happens if my employer doesn’t issue the 1095-C?

Employers can face IRS penalties for non-compliance, but employees should still file taxes on time even without the form.


The Future of 1095-C Forms

As healthcare regulations evolve, the 1095-b vs 1095-c forms remain central to the IRS’s efforts to monitor employer-provided health insurance. With digital filing systems becoming more common, both employers and employees can expect faster delivery, online access, and fewer paper forms in the coming years.


Conclusion

Form 1095-C is an important document for understanding the health coverage offered by your employer and how it relates to ACA requirements. Even though you don’t file it with your tax return, it’s still essential to keep it on hand for your records.

Take time to review your 1095-C each year—check the codes, verify the months you were offered coverage, and contact your employer if something looks incorrect. Keeping an accurate copy of your 1095-C tax form helps ensure a smooth tax season and prevents potential compliance issues down the road.
