If you bought health insurance through HealthCare.gov or a state exchange, one piece of January mail decides whether your tax return sails through or sits in an IRS holding pattern for months. That is Form 1095-A, the Health Insurance Marketplace Statement.
It arrives with no explanation, three columns of numbers that will not match what you actually paid, and a legal string attached: if you got one, you owe the IRS a Form 8962. Every figure and rule below was checked against IRS and HealthCare.gov pages on September 6, 2026, and describes tax year 2025 returns unless a different year is named.
What Form 1095-A Is and Who Gets One
The IRS describes Form 1095-A as the statement Marketplaces furnish so that individuals can take the premium tax credit, reconcile advance credit payments on their returns, and file an accurate return. The key point most people miss: it comes from the Marketplace, not from the IRS.
You get one if you or anyone in your household enrolled in a qualified health plan through the Marketplace, whether or not you took a subsidy. The Form 1095-A instructions require a separate form for each policy, with the information on each form relating only to that policy.
That is why multiple forms are normal. The IRS lists four reasons you might get more than one: household members were not all on the same plan, you updated your family information during the year, you switched plans, or family members were enrolled in different states.
Two things do not generate a 1095-A at all. The instructions tell Marketplaces not to furnish one for a catastrophic health plan or a stand-alone dental plan. Neither counts as a qualified health plan for premium tax credit purposes, which is a detail worth knowing before you go looking for a form that will never come.
When It Arrives and Where to Find It
The Form 1095-A instructions set a hard date: Marketplaces must file the annual report with the IRS and furnish the statements to individuals on or before January 31 for the prior calendar year of coverage. The IRS repeats the January 31 deadline in its consumer questions and answers.
HealthCare.gov is a little more conservative with expectations. It tells enrollees the form arrives by mail no later than mid-February and may be available in your Marketplace account anytime from mid-January to February 1.
To pull it online, log into your Marketplace account, select the application for the coverage year (not the current year’s application), choose “Tax Forms” from the menu, and download the PDF. HealthCare.gov adds one instruction people skip: if a form shows a “Corrected” status, download that one instead of the earlier version.
Unlike the other health coverage forms, this one is worth waiting for. The IRS says that if you are expecting a Form 1095-A you should wait to file until you receive it, while Forms 1095-B and 1095-C are not required to file and you should not wait on them.
How to Read the Three Parts
Part I, lines 1 through 15, is recipient information. The Marketplace state, the policy number, the insurance company’s name, the tax filer’s name and Social Security number, the spouse’s information if advance payments were made, the policy start and termination dates, and the address. If the policy ran all year, the dates read 1/1 and 12/31.
Part II, lines 16 through 20, lists covered individuals. Names, Social Security numbers, and the dates each person’s coverage started and ended. If more than five people were covered, the Marketplace files an additional page.
Part III, lines 21 through 32, is the part that matters for your taxes. One row per month, three columns, with annual totals on line 33. Here is what each column reports and where it lands on Form 8962.
| Column | What it reports | Where it goes on Form 8962 |
|---|---|---|
| A. Monthly enrollment premium | The total monthly premium for your plan, limited to the portion allocable to essential health benefits (plus any pediatric dental portion of a stand-alone dental plan) | Part II, column (a). Annual total to line 11, monthly amounts to lines 12 through 23 |
| B. Monthly second lowest cost silver plan (SLCSP) premium | The benchmark plan premium used to compute your credit, based on your coverage family for that month | Part II, column (b) |
| C. Monthly advance payment of premium tax credit | The subsidy the government already paid your insurer that month | Part II, column (f) |
Column A will often not equal what came out of your bank account. HealthCare.gov lists the usual reasons: your plan covered benefits beyond essential health benefits, your enrollment or family changed mid-month, or a stand-alone dental plan is in the mix. That does not automatically make it wrong.
Column B is the confusing one. The IRS defines it as the second lowest cost silver plan premium offered where you reside that applies to your coverage family. It is not the plan you bought, unless you happened to buy exactly that plan. It is the yardstick the credit is measured against, and it drives the whole calculation on Form 8962.
Column C is the number people are usually surprised by, because it is the real size of the advance premium tax credit that was paid on their behalf all year.
What to Do If It Never Arrives
The IRS answer is short: contact the Marketplace you enrolled through, and wait to receive the form before filing your taxes. For HealthCare.gov states, the Marketplace Call Center is 1-800-318-2596. For a state exchange, use that state’s site.
Before you call, check your online account. The electronic copy is usually posted before the paper one lands, and forms go to your last known permanent address, so a move you never reported is a common cause of a missing envelope.
One category of person will never get one and should stop looking: the IRS notes that individuals who did not buy through the Marketplace, including people on Medicaid or CHIP, do not receive Form 1095-A.
What to Do If It Is Wrong
There are two separate fixes, and choosing the wrong one wastes weeks.
Fix one: ask for a corrected form. If the coverage months, covered people, household information, or the enrollment premium in column A are wrong, contact the Marketplace. The Form 1095-A instructions require the Marketplace to report corrected information to the IRS and to you as soon as possible after discovering an error, with the CORRECTED box checked at the top. The Form 8962 instructions then tell you to use the corrected form and disregard the original. If you already filed, the IRS says a corrected or voided form may mean you need to amend.
You may also receive a form with the VOID box checked. That means a form was sent in error, typically for a stand-alone dental or catastrophic plan. Use neither the voided form nor the original it replaces.
Fix two: look up the SLCSP yourself. This is the one that catches people. If column B is blank or shows zero for a month someone was covered, or if you had a household change you never reported to the Marketplace, the number is unusable. The IRS is explicit that in this situation you do not have to request a corrected Form 1095-A. You must determine the correct applicable SLCSP premium for every affected month on your own.
The federal Marketplace publishes a lookup for exactly this at healthcare.gov/tax-tool, and both the IRS Form 8962 instructions and HealthCare.gov point you there. Household changes that can throw column B off include adding a newborn, moving, marrying, divorcing, or losing a dependent, which is one more reason to report a qualifying life event to the Marketplace when it happens rather than at tax time.
1095-A vs 1095-B vs 1095-C
Three forms, similar names, completely different jobs.
| Form | Who sends it | What it does |
|---|---|---|
| 1095-A, Health Insurance Marketplace Statement | The Marketplace | Reports your Marketplace coverage, premiums, benchmark premium and advance credit payments. Required to complete Form 8962 |
| 1095-B, Health Coverage | Health insurers and other coverage providers | Records who was covered and when. Not needed to file |
| 1095-C, Employer-Provided Health Insurance Offer and Coverage | Employers with 50 or more full-time employees | Records what coverage the employer offered. Part II can matter if you also had Marketplace coverage and need to show the job offer was unaffordable |
The IRS instruction is the same for all three: do not attach them to your return, keep them with your tax records. Note also that reporting entities are no longer required to mail Forms 1095-B and 1095-C automatically. If you request one, it must be provided by January 31 or 30 days after your request, whichever is later. That rule does not apply to Form 1095-A, which still must be furnished.
Yes, You Have to File Form 8962
The IRS states it plainly: if advance credit payments were made on your behalf, or if no advance payments were made but you want to claim the credit, you must file Form 8962 and attach it to your Form 1040, 1040-SR or 1040-NR. You must file even if your income is below the normal filing threshold.
Skipping it has two costs. The IRS says filing without reconciling your advance credit payments will delay your refund and may affect your eligibility for future advance credit payments, which means paying the full premium yourself. It also lists the situations that trigger Letter 12C, and the first one on the list is that it appears you were required to reconcile but did not include Form 8962. The IRS says it sends any refund due about six to eight weeks after it receives your response, and asks for that response within 20 days.
The Bottom Line
Form 1095-A is a three-column data sheet, not a bill. Read Part III, confirm the coverage months and the people are right, and check whether column B has a real number in every covered month. Those are the only judgment calls.
If the coverage facts are wrong, call the Marketplace and wait for a corrected form. If only column B is empty, do not call, use the tax tool. Then file Form 8962 with your return, because the money already paid to your insurer gets settled up either way. Since the enhanced subsidies lapsed, that settlement matters more than it used to, which is covered in what the ACA subsidy expiration changed and in the current ACA subsidy income limits.
If you are shopping rather than filing, the deadlines that govern whether you can enroll at all are in when open enrollment happens. And if the reconciliation leaves you with a balance you cannot pay at once, the same tactics that work on provider bills apply, starting with setting up a payment plan.
This is tax mechanics, not tax advice. For an actual return, work from the IRS instructions for your tax year or hand the form to a preparer.
