No, you do not need to enter Form 1095-C on your taxes. The IRS tells you to keep it with your records rather than attach it to Form 1040, because your employer sends the IRS its own copy.1Internal Revenue Service. Questions and Answers about Health Care Information Forms for Individuals If employer coverage was your only insurance last year and nobody in your household bought a Marketplace plan with subsidies, the form requires nothing from you at filing time. The situation changes if you or a family member received advance Premium Tax Credit payments, because the codes on the 1095-C determine how much of that credit you actually get to keep, and in 2026 the cost of getting that wrong went up sharply.
The One Scenario Where the Form Actually Matters
If you or someone on your tax return enrolled in a Health Insurance Marketplace plan and received advance payments of the Premium Tax Credit, you have to reconcile those payments on Form 8962 when you file.2Internal Revenue Service. Reconciling Your Advance Payments of the Premium Tax Credit The numbers that drive Form 8962 come from Form 1095-A, which the Marketplace sends you.3HealthCare.gov. How to Reconcile Your Premium Tax Credit The 1095-C enters the picture because of eligibility: under 26 U.S.C. ยง 36B, you cannot claim the Premium Tax Credit for any month your employer offered you coverage that was both affordable and provided minimum value.4Office of the Law Revision Counsel. 26 USC 36B – Premium Tax Credit The codes on your 1095-C are the IRS’s record of whether that offer existed.
A plan provides minimum value if it covers at least 60% of the total expected cost of covered benefits, and most employer plans clear that bar.5Internal Revenue Service. Minimum Value and Affordability For 2026, coverage is considered affordable if your required contribution for the lowest-cost self-only plan is 9.96% of household income or less.6Internal Revenue Service. Rev. Proc. 2025-25 – Indexing Adjustments for the Premium Tax Credit and Required Contribution Percentage If the offer meets both tests, you lose PTC eligibility for those months even if you declined the employer plan and bought Marketplace coverage anyway. Any advance credits you collected during those months come back as repayment on your return.
The 2026 Repayment Cliff
For the 2025 tax year and earlier, taxpayers with household income below 400% of the federal poverty line had caps on how much excess advance PTC they had to pay back. Those caps ranged from $375 to $3,250 depending on income and filing status.7Internal Revenue Service. 2025 Instructions for Form 8962
Starting with plan year 2026, the caps are gone. Under Section 71305 of Public Law 119-21, taxpayers who received more advance PTC than they were entitled to must repay the entire excess, regardless of income.8Centers for Medicare and Medicaid Services. Are There Limits to How Much Excess Advance Payments of the Premium Tax Credit Consumers Must Pay Back A lower-income taxpayer who in prior years might have owed a few hundred dollars for the same mistake could now owe thousands. That is the practical reason to look at the 1095-C before you file instead of filing it away without reading it.
How to Read the Codes That Decide Your Credit
The three lines in Part II are what matter for Premium Tax Credit reconciliation. Each one has an entry for every month of the year.9Internal Revenue Service. Instructions for Forms 1094-C and 1095-C (2025)
Line 14 reports what your employer offered. Code 1A is a “qualifying offer” of affordable, minimum-value coverage for you with coverage also available to your spouse and dependents. Code 1E means minimum-value coverage was offered to you, your spouse, and your dependents. Code 1H means no offer that month. If Line 14 shows 1A or 1E for a given month and you were collecting advance PTC on a Marketplace plan during the same month, expect to repay that month’s credits.
Line 15 shows what you would have paid monthly for the lowest-cost self-only plan. This is the number the IRS compares against the 9.96% affordability threshold. If the figure on Line 15, multiplied by twelve, is more than 9.96% of your household income, the offer was not affordable for that month and your PTC may still stand.
Line 16 provides context, such as code 2C to show you enrolled in the coverage, or codes marking months you were not a full-time employee or that the employer used a safe harbor to measure affordability.
Compare the 1095-C and the 1095-A month by month. If your employer’s affordable offer began in April but you kept Marketplace coverage with advance credits through December, you owe back the credits for those nine months in full under the 2026 rules.
The Family Coverage Test Is Separate
If your spouse or dependents bought their own Marketplace coverage, do not use your self-only cost to judge their eligibility. Before 2023, affordability for the whole family turned on the cost of employee-only coverage, which locked families out of subsidies even when the family plan was unaffordable. The IRS fixed that beginning in 2023 by creating two separate tests: self-only coverage cost for you, and family coverage cost for your spouse and dependents.10HealthCare.gov. Affordable Coverage – Glossary
Under the current rules, your family members can qualify for Premium Tax Credits on their own Marketplace plan if your employer’s family coverage exceeds 9.96% of household income for 2026, even if your self-only coverage is affordable. Check both numbers independently.
If You Didn’t Receive a Form
Starting in 2024, employers no longer have to mail Form 1095-C to every employee automatically. They can satisfy the furnishing rule by posting a clear notice that the form is available on request. If you ask, the employer must provide the form within 30 days or by January 31 of the following year, whichever is later.9Internal Revenue Service. Instructions for Forms 1094-C and 1095-C (2025)
Check your employer’s HR portal or website for the notice if a form never arrived. You can also file your return without it. The IRS confirms you do not need to wait for a 1095-B or 1095-C to file.11Internal Revenue Service. Gathering Your Health Coverage Documentation for the Tax Filing Season If you are reconciling advance PTC, though, request the form and look at it before you send the return.
If the Form Is Wrong
Errors on Line 14 can make it look like you had an affordable offer when you didn’t, which can cost you Premium Tax Credits you were legitimately entitled to. Contact your employer’s HR or payroll department, since employers are the only ones who can issue a correction. Common problems are a wrong coverage start date, an incorrect Social Security number, or a Line 14 code that misrepresents what was actually offered. Once corrected, the employer issues a replacement marked “CORRECTED.”
Wait for the corrected form before filing Form 8962. Filing with the wrong data invites an IRS notice demanding repayment of credits, and sorting that out afterward involves correspondence audits and refund delays. If the correction will not arrive before April, request an extension.
One procedural note: if you took advance PTC and skip Form 8962, the IRS will reject an e-filed return outright, and a paper return will generate follow-up letters that delay any refund.12Internal Revenue Service. How to Correct an Electronically Filed Return Rejected for a Missing Form 8962
State Returns in Mandate States
The federal return does not require your 1095-C, but a few states with their own individual health insurance mandates use the data. California requires employers with self-insured plans to transmit 1094/1095-C data to the Franchise Tax Board. Massachusetts issues a separate state form, the MA 1099-HC, to employees enrolled in a state-regulated plan. New Jersey requires employers to file 1095-C data (Parts I and III only) with the state Division of Taxation. Rhode Island and the District of Columbia enforce individual mandates with penalties. Vermont has a mandate without a financial penalty. If you lived in one of these states and had any coverage gap during the year, check the state’s filing instructions to see whether the form’s data is needed to avoid a state-level penalty.
COBRA After Leaving a Job
If you left a job during the year and elected COBRA continuation coverage, you may still get a 1095-C from the former employer. For self-insured plans, the employer reports COBRA enrollment on Line 14 using code 1G, which identifies coverage provided to someone who was not an active employee that month. Line 15 is left blank because the affordability test does not apply to COBRA participants.9Internal Revenue Service. Instructions for Forms 1094-C and 1095-C (2025) If the former employer’s plan was fully insured, the insurance carrier reports the coverage on Form 1095-B instead. Either way, COBRA counts as minimum essential coverage, which matters in states with an individual mandate.
