IRS Form 1095-C is the statement large employers send each full-time employee every year, showing what health coverage was offered, what it cost, and which months it applied to. It matters at tax time because the numbers and codes on it decide whether you qualified for Premium Tax Credits if you bought a Marketplace plan, and whether you may owe back any advance credits you received.
Who Gets a 1095-C
The form comes only from Applicable Large Employers: organizations that averaged at least 50 full-time employees, including full-time equivalents, in the prior calendar year.1Legal Information Institute. 26 USC 4980H(c)(2) – Applicable Large Employer If your employer is smaller, you won’t receive a 1095-C. You might instead get a Form 1095-B from an insurance carrier or a smaller self-insured employer, which simply confirms you had coverage.2Internal Revenue Service.

Full-time for this purpose means averaging at least 30 hours per week or 130 hours per month, counting all hours you were paid or entitled to payment for.3Internal Revenue Service. Identifying Full-Time Employees If you hit full-time status for even one month, your employer must issue you the form and report on all twelve months.4Internal Revenue Service.

Whether you actually enrolled in the plan doesn’t change anything. The form comes whether you accepted the offer, declined it, or waived coverage entirely.5Internal Revenue Service. Questions and Answers About Information Reporting by Employers on Form 1094-C and Form 1095-C One boundary worth knowing: if you left a job during the year and took COBRA coverage, expect the months after your employment ended to show as “no offer” on the form. That’s the correct reporting, not an error.6Internal Revenue Service. Instructions for Forms 1094-C and 1095-C
What the Form Shows
There are three parts. Part I is straightforward identification: your name, address, and Social Security number, plus your employer’s information. Check the SSN carefully, because a mismatch here can hold up your refund or generate an IRS notice.
Part II: The Codes That Matter
Part II carries the substance, reported month by month with two lines of coded values.
Line 14 uses Series 1 codes to describe the type of coverage offered. Code 1A signals a “qualifying offer” of minimum-value coverage priced at or below the federal poverty line affordability threshold. Code 1E signals minimum-value coverage extended to you, your dependents, and your spouse. Other codes describe offers to you alone, or no offer at all.6Internal Revenue Service. Instructions for Forms 1094-C and 1095-C
Line 15 shows the employee required contribution: your share of the monthly premium for the cheapest self-only plan your employer offered that met minimum value. This is the number the IRS uses to test affordability. It reflects the least expensive qualifying option even if you actually enrolled in something more expensive, like a family plan. If the employee cost is zero, the line shows “0.00” rather than a blank.7Internal Revenue Service. 2025 Instructions for Forms 1094-C and 1095-C
Line 16 uses Series 2 codes for context. Code 2C means you were actually enrolled that month. Code 2B means you weren’t full-time that month. Codes 2F, 2G, and 2H tell the IRS which affordability safe harbor your employer relied on: W-2 wages, federal poverty line, or rate of pay.7Internal Revenue Service. 2025 Instructions for Forms 1094-C and 1095-C
Part III: Only for Self-Insured Plans
Part III applies only if your employer runs a self-insured plan, meaning the company pays claims directly rather than buying coverage from an insurance carrier. When it applies, it lists every person enrolled under the plan (you, spouse, dependents) with their SSN or date of birth, month by month. Confirm every household member who had coverage appears there.6Internal Revenue Service. Instructions for Forms 1094-C and 1095-C With a traditional insured plan, Part III is blank.
How It Affects Your Tax Return
Do not attach Form 1095-C to your return. Your employer files it with the IRS directly. Keep your copy with your tax records.2Internal Revenue Service. Questions and Answers About Health Care Information Forms for Individuals
The real impact is on Premium Tax Credit eligibility. If you enrolled in a Marketplace plan and received advance premium tax credits, you’ll reconcile them on Form 8962. Whether you were entitled to those credits in the first place depends on what your employer offered you: if the employer plan met both the minimum value and affordability standards, you generally weren’t eligible for a Marketplace subsidy.2Internal Revenue Service. Questions and Answers About Health Care Information Forms for Individuals8HealthCare.gov. See Your Options If You Have Job-Based Health Insurance
For 2026, employer coverage counts as affordable if your share of the monthly premium for the lowest-cost self-only plan is less than 9.96% of household income.9Internal Revenue Service. Rev. Proc. 2025-25 That’s why line 15 matters so much. If the dollar amount is overstated, you might look ineligible for subsidies you actually qualify for. If it’s understated, you could claim credits you’ll later have to repay.
The IRS suggests holding onto information returns like the 1095-C for at least three years from the due date, in case questions come up later about your credits or coverage.7Internal Revenue Service. 2025 Instructions for Forms 1094-C and 1095-C
If Your Form Is Missing or Wrong
Don’t wait on a missing 1095-C to file. The IRS allows you to file using other records of your coverage, such as pay stubs showing premium deductions or enrollment confirmations. If you believe you should have received a form, contact your employer’s HR department.2Internal Revenue Service. Questions and Answers About Health Care Information Forms for Individuals
If something on the form looks wrong, use the phone number on line 10 to reach HR. Your employer is responsible for issuing a corrected form to you and filing the correction with the IRS. Errors on coverage dates or premium amounts deserve prompt attention because they feed directly into your credit calculation. When line 15 or the coverage months are wrong, wait for the corrected form before filing. Keep both the original and the corrected copy.
When to Expect Your Form
For the 2025 tax year, your employer must furnish your copy of Form 1095-C by March 2, 2026.10Internal Revenue Service. 2025 Instructions for Forms 1094-C and 1095-C If a deadline lands on a weekend or holiday, it moves to the next business day.
State Coverage Mandates
The federal individual mandate penalty has been $0 since 2019, so there’s no federal tax penalty for being uninsured. Several jurisdictions run their own mandates with real financial penalties: California, Massachusetts, New Jersey, Rhode Island, and the District of Columbia. Penalties in those places can reach into the thousands depending on household income.
If you live in one of them, the information on your 1095-C may also feed state reporting. California, New Jersey, Rhode Island, and the District of Columbia generally accept the federal 1095-C for state purposes. Massachusetts uses its own MA Form 1099-HC, filed separately by your insurer or employer. Deadlines and methods vary, so check with your state tax agency if you want to confirm compliance.
