Insurance Curator Your Health Insurance Marketplace Statement — officially known as Form 1095-A — is a critical document if you or anyone in your household purchased health insurance through the Marketplace (Exchange) in a given year. This form reports your monthly enrollment, premiums, and any advance premium tax credits (APTC) you received. It directly impacts your federal tax return. Unfortunately, mistakes on or about your Health Insurance Marketplace Statement are common, and they can delay your refund, trigger IRS notices, or even reduce your tax credit. In this exhaustive guide, we’ll walk through the most frequent errors, provide real-world examples, and show you exactly how to fix each one. By understanding your Health Insurance Marketplace Statement: Understanding Your Form 1095-A inside out, you’ll avoid costly slip-ups and keep your tax filing smooth.
Whether you are a first-time enrollee or a seasoned Marketplace user, this deep dive will give you the confidence to handle your 1095-A correctly. We’ll also recommend essential resources — like the book Health Insurance: Explained Like You’re 5 — that break down these complex rules into plain language.
Mistake #1: Failing to Reconcile Advance Premium Tax Credits (APTC)
The most common mistake is not reconciling the APTC you received during the year with the actual premium tax credit you qualify for based on your final income. The Marketplace estimated your credit using income you projected when you enrolled. If your actual income ends up higher or lower, the credit must be adjusted on your tax return. Many taxpayers forget to complete Form 8962 (Premium Tax Credit) alongside their 1040.
Example: Maria enrolled in a Silver plan in 2024, estimating an income of $35,000. She received $200 per month in APTC. By year-end, her actual income was $42,000. Because she earned more, she is entitled to a smaller credit. If she doesn’t reconcile, the IRS will claw back the excess credit, and she may owe money. Conversely, if she earned less (e.g., $28,000), she could be missing out on additional credit.
How to Fix: Use the information from Parts II and III of your Health Insurance Marketplace Statement to fill out Form 8962. The form will calculate the correct credit. If you owe, pay with your return; if you’re due more, it will increase your refund. The IRS provides worksheets, and tax software like TurboTax handles this automatically – but only if you enter your 1095-A data correctly.
Mistake #2: Ignoring the Statement or Missing Filing Deadlines
A surprising number of people simply discard their Health Insurance Marketplace Statement or overlook it entirely. Because the form is mailed separately (usually in late January), it can get buried under holiday mail or lost in a pile. If you don’t have the form when you file, you cannot accurately report APTC. The IRS will likely reject an e-filed return that doesn’t include the 1095-A data.
How to Fix: Keep an eye on your mailbox and your Marketplace account online. If you haven’t received your 1095-A by February 15, log in to HealthCare.gov or your state’s Marketplace portal to download a copy. If you still cannot find it, call the Marketplace call center. Do not guess the numbers; using incorrect figures can trigger an audit. And remember: you don’t need to wait for the form to file if you file an extension — but you must eventually include it.
Mistake #3: Incorrectly Reporting Household Income or Family Size
Your Health Insurance Marketplace Statement itself doesn’t ask for income, but the reconciliation process on Form 8962 does. Common errors here include:
- Forgetting to include all household members’ incomes (e.g., a spouse’s part-time job, a dependent’s investment income).
- Misreporting family size — the number of people you claimed as dependents vs. the number covered by the Marketplace plan. The family size used for premium tax credit may differ from your tax-filing dependent count if some household members are not on the policy.
Example: Kevin and his wife have two children. On their Marketplace application, they listed all four as covered. But on their taxes, they claimed only Kevin and his wife as dependents (the kids had their own income). Because the Marketplace expected coverage for four people, the APTC was based on a larger family. The IRS will require reconciliation using the actual family size from the tax return. This mismatch can cause a repayment.
How to Fix: Carefully compare the family size used in Part III of your Health Insurance Marketplace Statement (column C shows the number of covered individuals) with your tax return’s dependency count. If they differ, you must adjust Form 8962. The IRS publication 974 can guide you. If you realize an error on your Marketplace application (like forgetting to remove a child who turned 26), contact the Marketplace to update your record before filing.
Mistake #4: Errors in Monthly Premium Amounts or APTC Columns
The Health Insurance Marketplace Statement has three parts. Part II lists monthly enrollment premiums, Part III shows the monthly APTC amount. These numbers come from the Marketplace, but they are not always correct. Data entry errors by the Marketplace or by a state exchange happen. Sometimes the premiums for a subsidized plan are wrong because the second-lowest-cost Silver plan (SLCSP) was miscalculated.
How to Spot Mistakes: Compare your monthly premium amounts with your insurance card or billing statements. If you paid a different amount, there’s a discrepancy. Similarly, check the APTC column: if you changed plans mid-year, the amounts may not align with the months you had coverage.
How to Fix: Do not file with incorrect numbers. Contact the Marketplace immediately. They can issue a corrected Health Insurance Marketplace Statement (Form 1095-A). You should receive a new form within 30 days. If the error is on the Marketplace’s side, you have no liability — but you need the correct data to reconcile accurately. Use the corrected form when filing.
Mistake #5: Overlooking Mid-Year Life Changes and Special Enrollment
Life events like marriage, divorce, birth of a child, or a move to a different state can change your eligibility for premium tax credits. If you had a qualifying life event and enrolled in a new plan during the year, your Health Insurance Marketplace Statement will only reflect the months you were covered under that particular plan. Many people forget to reconcile the two separate coverage periods correctly.
Example: James had a Marketplace plan from January to June. He got married in July and added his spouse to a new plan from July to December. The Marketplace issued two separate 1095-A forms — one for each plan. James tried to enter only the first form, ignoring the second. His tax software then miscalculated his credit because the months without APTC (if any) were treated incorrectly.
How to Fix: If you had more than one policy, you should receive multiple Health Insurance Marketplace Statement forms. Combine all of them on Form 8962 — it has space for up to three policies. Each policy’s months and amounts must be entered separately. The IRS instructions explicitly cover multi-policy scenarios. If your softwaredoesn’t handle it well, consider using a professional tax preparer who deals with Marketplace statements annually.
Mistake #6: Forgetting to Include Form 1095-A When E-Filing
Even if you don’t owe any reconciliation amount, the IRS requires you to attach the information from your Health Insurance Marketplace Statement to your return. When e-filing, tax software will ask you to enter the data from the form. If you skip this step, the software may not be able to e-file at all, or it may file without the premium tax credit computation. The IRS will later send a notice asking for the missing information, delaying your refund.
How to Fix: Before clicking “submit,” double-check that your tax return includes Form 8962 (if you received APTC) or that the Premium Tax Credit worksheet is completed. Many filers mistakenly think they don’t need to reconcile if they “paid back” their credit voluntarily. That’s not correct — reconciliation is mandatory. Also, keep a copy of the Health Insurance Marketplace Statement with your tax records for at least three years.
How to Fix Mistakes: A Step-by-Step Approach
If you discover an error on or related to your Health Insurance Marketplace Statement, follow these steps:
- Gather all documents. Pull your Form 1095-A, your tax return draft, your insurance billing statements, and any correspondence from the Marketplace.
- Identify the specific error. Is the mistake on the form itself (wrong premium/APTC), or is it a reporting error on your return (wrong family size)?
- Correct the source. If the Marketplace made a data error, call the Marketplace (1-800-318-2596) and request a corrected 1095-A. If the error is your household composition or income, you may need to amend your Marketplace application first.
- File an amended tax return if needed. If you already filed using incorrect 1095-A data, file Form 1040-X (Amended U.S. Individual Income Tax Return). Attach a corrected Form 8962. You can do this up to three years after the original filing deadline.
- Consult a professional. The rules around premium tax credit reconciliation are complex. A CPA or enrolled agent who works with health insurance taxes can save you thousands.
Expert Insights: Why These Mistakes Happen — and How to Avoid Them
Insurance experts point to two root causes: complexity and timing. The Health Insurance Marketplace Statement arrives after many people have already started their taxes. “The form itself is straightforward,” says a veteran tax preparer, “but the interplay between APTC, family size, and income is where most people slip.” Another issue is that many enrollees do not update their income or family changes mid-year. The Marketplace adjusts APTC only when you report changes proactively.

Frequently Asked Questions About the Health Insurance Marketplace Statement
Q: What is a Health Insurance Marketplace Statement?
A: It’s Form 1095-A, issued to anyone who enrolled in health coverage through the Marketplace. It shows your monthly premiums, advance premium tax credits (APTC), and covered individuals. You need it to reconcile your tax credit on your federal return.
Q: Do I have to file my 1095-A with my tax return?
A: You don’t physically attach the form, but you must report its data on Form 8962. If you e-file, your tax software will walk you through entering the numbers.
Q: What if my 1095-A is wrong?
A: Contact the Health Insurance Marketplace immediately. They will investigate and send a corrected form. Use that corrected version when filing your taxes.
Q: Can I file my taxes without my 1095-A?
A: Technically, yes, if you didn’t receive APTC. But if you did receive APTC, you must reconcile. Filing without the form will lead to an IRS notice. If you haven’t received it by mid-February, request a copy online or by phone.
Q: How long do I need to keep my 1095-A?
A: Keep it with your tax records for at least three years from the date you filed your return (or from the original due date, whichever is later). The IRS may ask for it during an audit.
Q: I paid back my APTC during the year — do I still need the statement?
A: Yes. Voluntary repayment does not replace the formal reconciliation. You still must file Form 8962 to show exactly how your APTC was resolved.
