Marketplace insurance: the 1095-A and Form 8962

If anyone on your return had health coverage through the Marketplace, the return is not finished until Form 8962 is attached to it. The 1095-A is the statement that feeds that form, and a return filed without reconciling it is one of the most common ways a straightforward e-file gets rejected.

Form 8962 is not optional

The premium tax credit is usually paid in advance, month by month, straight to the insurer so your share of the premium is lower. Because it was estimated from the income you reported when you enrolled, it has to be squared up against your actual income for the year. Form 8962 is where that happens.

If advance payments were made for anyone on the return, the return has to carry Form 8962. Filing without it means an electronic return comes back rejected, and a paper one draws a letter asking for the missing form before any refund is released. Filing an extension does not change it; the reconciliation still has to happen.

There is a second reason to file the form even when no advance payments were made: the credit can be claimed at filing time instead, and Form 8962 is the only way to claim it.

The three columns

Part III of the 1095-A has one row per month and three columns that matter.

• Column A is the enrollment premium: what the plan you chose actually cost each month.
• Column B is the premium for the second-lowest-cost silver plan available to your household. You may never have looked at that plan, but it is the benchmark the entire credit is measured against.
• Column C is the advance credit that was paid to the insurer on your behalf that month.

Column B is the one that goes wrong. It can be blank or zero, particularly when no advance payments were made or when the household changed mid-year, and it can be wrong when a birth, a move or a change in who was covered was not reported to the Marketplace. When column B is missing or does not fit the household, the correct benchmark has to be looked up with the tax tool on the Marketplace website rather than copied from the form.

Reconciling, and what it costs

Form 8962 compares the credit you were entitled to, based on your final household income and family size, against what column C says was already paid.

If the advance payments were less than the credit you qualify for, the difference is a refundable credit on your return. If they were more, the excess is added back to your tax.

That repayment is capped for households below four times the federal poverty line. Below twice the poverty line, repayment stops at $375 on a single return and $750 on every other filing status. From two up to three times the poverty line, the caps are $975 and $1,950. From three up to four times, they are $1,625 and $3,250.

For 2025 the older rule that cut the credit off entirely above four times the poverty line is not in force. Above that line the credit phases down rather than disappearing, with your expected contribution capped as a share of household income. A higher income than you projected can therefore still leave a credit in place, while removing the protection of the repayment cap.

Keeping the estimate current

The single most useful habit with Marketplace coverage is telling the Marketplace when something changes during the year, not at the end of it: a raise, a new job, a job ending, a marriage, a divorce, a birth, someone becoming eligible for employer coverage or Medicaid. Each of those changes the credit, and reporting it adjusts the advance payments while there are still months left to adjust.

If the form never came

The 1095-A is mailed and is also posted in your account on the Marketplace website, usually under tax forms for the coverage year. State-run Marketplaces post it in their own accounts. If it is missing, wrong or covers people who were not in your household, contact the Marketplace for a corrected form rather than estimating the numbers.
