How to Read Form 1095-A: Premiums, Credits, and Form 8962

Form 1095-A, the Health Insurance Marketplace Statement, is organized into three parts: Part I identifies the policy and policyholder, Part II lists everyone covered and the months they were enrolled, and Part III shows the monthly premium and tax credit figures you carry onto IRS Form 8962. To read Form 1095-A, work through those parts in order and check each field against your own records before using any number on your return.¹

Part I: Policy and Policyholder

The top of the form identifies you as the policyholder. It shows your name, Social Security number, and the policy number the Marketplace assigned to your plan. The IRS uses these fields to match the coverage record to your tax return.¹ Marketplace plans are required to report this information under federal law.²

A misspelled name or other identifying typo in Part I usually will not affect your tax calculation, but it is still worth flagging with the Marketplace so records stay consistent.³

Part II: Who Was Covered and When

Part II lists every person covered by the policy along with their Social Security numbers and the months each of them was enrolled. Read this section against your own memory of the year. If someone joined the plan mid-year, dropped off after a birthday or job change, or was added after a life event, the start and end months here should match what actually happened. Incorrect dates can delay processing or generate IRS correspondence later.

Part III: Monthly Premiums and Credits

Part III is where the numbers that matter for your taxes live. It runs one row per month, January through December, with three columns of dollar figures.

Column A, Monthly Enrollment Premium. The full cost of your plan for that month before any tax credits were applied. This is the gross price the Marketplace charged, not what you actually paid out of pocket.¹
Column B, Second Lowest Cost Silver Plan (SLCSP) Premium. A benchmark figure the Marketplace assigns based on silver-level plan options in your area. It does not reflect the plan you actually chose; it is the number used to calculate the maximum credit you can receive. This value can change if your household size shifted during the year.¹
Column C, Monthly Advance Payment of Premium Tax Credit. The amount the government sent directly to your insurer that month to reduce your premium. If you paid full price and did not receive financial help, this column shows zero.¹

When you read a row, think of it as a short story: Column A is what your plan cost, Column C is what the government already paid toward it on your behalf, and Column B is the yardstick the IRS uses to decide whether the amount in Column C was too much, too little, or right for your final income.

When Column B Is Blank or Zero

Column B sometimes comes through empty or showing zero for a month you were actually enrolled. That happens, and you can fix it yourself. Look up the correct benchmark premium using the HealthCare.gov tax tool before you complete Form 8962.⁴ Without a valid Column B figure, the credit math on Form 8962 will not work.

Checking the Form for Errors

Before you use any of these numbers on your return, compare each column against your own records: pay stubs from the Marketplace, bank statements showing what you paid, and enrollment confirmations. The most common errors involve the number of people covered, the months of coverage, the monthly premium amounts, and the SLCSP benchmark figures. Mistakes in Part I identifying information usually will not affect your tax calculations, but incorrect financial data in Part III will.³

If anything is wrong, contact your Marketplace right away and request a corrected version. For the federal Marketplace, call 800-318-2596. State-based marketplaces handle their own corrections. Filing with incorrect data creates a mismatch that can delay your refund or generate IRS notices later.

If You Never Received the Form

The Marketplace mails Form 1095-A by the end of January for the prior year’s coverage. If yours has not arrived, you can download it. Log in to your HealthCare.gov account, select the application for the tax year in question (not the current year’s application), choose “Tax Forms” from the menu, and download the PDF.⁵ If you enrolled through a state-based marketplace, check that marketplace’s website instead.

How the Numbers Move to Form 8962

Reading Form 1095-A is a step toward completing Form 8962, the Premium Tax Credit form you file with your return.⁶ The transfer is direct. Column A on your 1095-A goes into column (a) on Form 8962. Column B goes into column (b). Column C goes into column (f).⁷

A couple of situations complicate that clean copy-across. If you had more than one 1095-A for the same month—say you switched plans mid-year—add the amounts together for that month before entering them.⁷ And if the policy on your 1095-A covered people who belong to a different tax household, such as after a divorce or when a dependent files their own return, the premium and credit amounts get split between the filers using Part IV of Form 8962 rather than transferred whole.⁸

Once the monthly figures are on Form 8962, the form compares the year’s advance payments (the totals from Column C) against the credit your final income actually entitles you to. The legal basis is federal tax law, which requires that the credit be reduced by any advance payments and that excess payments be added back to your tax liability.⁹ If the advance payments were too high, you owe the difference; if they were too low, the extra credit reduces your tax or increases your refund.⁷

That is the practical reason to read Form 1095-A carefully before you file. Every dollar of tax impact traces back to a figure printed in Part III, and any error you carry forward becomes an error on your return.
