Form 1095-A and Form 1095-C both report health coverage, but only one of them changes your tax bill. Form 1095-A comes from the Health Insurance Marketplace and feeds directly into your Premium Tax Credit calculation, which means it can raise your refund or create a balance due. Form 1095-C comes from a large employer and is an informational record you keep with your tax documents but do not attach to your return. Which one you receive depends entirely on where your coverage came from that year.
Where Each Form Comes From
The Marketplace sends Form 1095-A to anyone who enrolled in a qualified health plan through HealthCare.gov or a state exchange.1Internal Revenue Service. About Form 1095-A, Health Insurance Marketplace Statement It lists everyone in the household covered by the plan and shows, month by month, the total premium, the Second Lowest Cost Silver Plan (SLCSP) premium for your area, and any Advance Premium Tax Credit (APTC) sent directly to your insurer to lower your monthly bill.2HealthCare.gov. How to Use Form 1095-A, Health Insurance Marketplace Statement Catastrophic plans and dental-only Marketplace plans do not generate a 1095-A.3Centers for Medicare & Medicaid Services (CMS). What is Form 1095-A?
You can find your 1095-A by logging into your Marketplace account, opening the prior year’s application, and downloading the PDF under “Tax Forms.” Paper copies arrive by mail no later than mid-February.2HealthCare.gov. How to Use Form 1095-A, Health Insurance Marketplace Statement If it has not arrived by then, contact the Marketplace that issued your coverage before filing. The IRS recommends waiting for the form rather than filing without it.4Internal Revenue Service. Health Insurance Marketplace Statements
Form 1095-C comes from large employers, generally those with 50 or more full-time employees counting full-time equivalents, and it goes to every employee who was full-time for at least one month of the year.5Internal Revenue Service. 2025 Instructions for Forms 1094-C and 1095-C The reporting requirement sits under 26 U.S.C. § 6056 and ties into the employer shared responsibility rules in 26 U.S.C. § 4980H.6Office of the Law Revision Counsel. 26 US Code 4980H – Shared Responsibility for Employers Regarding Health Coverage For the 2025 tax year, employers must furnish Form 1095-C by March 2, 2026, an automatic extension from the standard January 31 deadline. It usually arrives from HR or payroll around the same time as your W-2, or slightly later.
Some people get both forms in the same year. That is normal if you had employer coverage for part of the year and Marketplace coverage for the rest, or if a family member was on a different plan than you.
How Form 1095-A Changes Your Tax Return
This is where 1095-A earns its reputation as the form you cannot ignore. If anyone in your household received APTC or you want to claim the Premium Tax Credit, you must complete Form 8962 and attach it to your return, even if you would not otherwise be required to file.7Internal Revenue Service. 2025 Instructions for Form 8962 Premium Tax Credit (PTC) The credit itself is authorized under 26 U.S.C. § 36B, which ties the subsidy to the difference between your area’s SLCSP premium and a percentage of your household income.8Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan
Form 8962 compares what the Marketplace estimated your income would be when you enrolled with what you actually earned. If your actual income came in higher than projected, you received too much APTC and owe some of it back. If your income was lower, you may get a larger refund. The numbers you copy from your 1095-A drive the whole reconciliation.7Internal Revenue Service. 2025 Instructions for Form 8962 Premium Tax Credit (PTC)
2026 Change: No More Repayment Caps
In prior tax years, the IRS capped how much excess APTC you had to repay based on your income. A single filer under 200% of the federal poverty line in 2025, for instance, owed back no more than $375 even if the actual overpayment was larger. Starting with tax year 2026, those caps are gone. If your APTC exceeds the credit you actually qualified for, you owe the full difference.9Federal Register. Patient Protection and Affordable Care Act, HHS Notice of Benefit and Payment Parameters for 2027 That makes it more important to report income changes to the Marketplace during the year. A raise, a new job, or an unexpected windfall you do not report can turn into a real tax bill the following April.
What Happens If You Skip Form 8962
Filing without Form 8962 when APTC was paid on your behalf is one of the fastest ways to freeze your refund. The IRS typically sends Letter 12C requesting the missing form or a copy of your 1095-A.10Internal Revenue Service. Understanding Your Letter 12C Until you respond, the credit stays in limbo. Most of these cases come down to a missing document or a data-entry error, but the delay can stretch weeks if you are slow to reply.
What Form 1095-C Does at Tax Time
Here is the key difference most people miss: you do not attach Form 1095-C to your return, and in most cases it has no effect on your refund or balance due. The form exists so the IRS can verify that your employer met its coverage obligations. Keep it with your tax records. There is no 8962-style reconciliation.
The one situation where a 1095-C matters at tax time is if the coverage your employer offered was unaffordable or failed to provide minimum value. In that case, you may have been eligible to buy a Marketplace plan with premium tax credits. The codes and premium figures on the 1095-C help the IRS confirm whether you legitimately qualified. If your employer’s coverage was affordable and met minimum value, you generally cannot claim the Premium Tax Credit even if you chose a Marketplace plan on your own.11Internal Revenue Service.

If You Got Neither Form
Coverage that did not come from the Marketplace or a large employer usually shows up on Form 1095-B instead. That includes Medicare Part A, Medicaid, CHIP, TRICARE, VA coverage, small employer self-insured plans, individual-market policies bought directly from an insurer, and SHOP coverage.12Internal Revenue Service. 2025 Instructions for Forms 1094-B and 1095-B Like 1095-C, 1095-B is not attached to your return. It simply confirms the months you had qualifying coverage, and the issuer sends a copy to the IRS as well.
Fixing a Wrong or Missing Form
Errors happen: a wrong Social Security number, an incorrect month, a premium amount that does not match your records. The fix depends on which form is affected.
For a wrong 1095-A, contact the Marketplace that issued your coverage. If you enrolled through HealthCare.gov, call the Marketplace Call Center at 1-800-318-2596 (TTY: 1-855-889-4325).13Centers for Medicare & Medicaid Services (CMS). Form 1095-A Corrected Cover Letter Do not file with numbers you know are wrong. Wait for the corrected form, then complete Form 8962 using the updated figures. If you already filed, you may need to amend the return.
For a wrong 1095-C, contact your employer’s HR or benefits department. The employer files a corrected version with the IRS (marked with a “CORRECTED” checkbox) and furnishes you a copy. If the employer uses online delivery, the corrected form must be provided within 30 days of your request.5Internal Revenue Service. 2025 Instructions for Forms 1094-C and 1095-C
If a form never arrives, the steps are similar. For a missing 1095-A, the IRS specifically advises waiting for it before filing.4Internal Revenue Service. Health Insurance Marketplace Statements For a missing 1095-C, you can usually file on time using coverage information you already know, since the form does not get attached to your return anyway.
How Long to Keep Them
Hold onto every 1095 form, along with any Form 8962 you filed, for at least three years from the date you filed the related return. That matches the standard IRS statute of limitations for audits.14Internal Revenue Service. How Long Should I Keep Records? The IRS also recommends keeping broader records of your health coverage, since you may need them to verify a Premium Tax Credit claim if your return is examined.15Internal Revenue Service. Topic No. 305, Recordkeeping Digital copies are fine. Just back them up somewhere you can actually find them two tax seasons from now.
