What would you owe back?

Through the 2025 tax year, a household under four times the poverty line could not be made to repay more than a set amount, whatever the estimate got wrong. Those limits ran from a few hundred dollars to a few thousand depending on income and filing status, and for most families they were the difference between an unpleasant surprise and an unpayable one.

They were removed for the 2026 plan year. If the Marketplace paid more toward your premium than your final income entitled you to, the entire difference is now added to your tax bill. There is no longer a ceiling at any income level.

This applies to the return you will file in early 2027 for the 2026 plan year.

Premium help stops entirely above four times the federal poverty level. It does not taper off. It stops. Go one dollar over and you were not eligible for any premium tax credit that year, so every dollar the Marketplace paid your insurer from January onward comes back.

For a household receiving a few hundred dollars a month, that is a four-figure bill arriving with the tax return. It is the single largest avoidable tax event in this part of the code, and it usually turns on a bonus, a second job or a good quarter of self-employment income that nobody thought to report.

The estimator above marks that line, so you can see how close you are before the year closes.

1. Your Form 1095-A arrives. The Marketplace sends it by late January. Column C shows exactly what was paid on your behalf, month by month.

2. Your final income is calculated on your return as modified adjusted gross income.

3. Form 8962 reconciles the two. Part II compares the credit you received against the credit your final income entitled you to.

4. The difference lands on your return. Too much received becomes a balance due, reducing a refund or increasing what you owe.

Form 8962 must be filed even when you owe nothing, and even when you would not otherwise have to file at all. Skipping it can end your premium help for the following year.

Report income changes within 10 days. A raise, a new job, a freelance payment: telling the Marketplace lowers the advance credit for the rest of the year, so less builds up to be repaid. This is the one that works all year and the one most people skip.

Take less of the subsidy upfront. You are not obliged to take the full advance payment. Take part of it and claim the rest as a lump sum when you file, and the repayment risk goes to nothing.

Lower your countable income before the year ends. Deductible traditional IRA, 401(k) and HSA contributions all reduce modified adjusted gross income. Late in the year this is often what puts a household back under the cliff.

Bring it to someone before you file. We prepare the return and the Form 8962 together, which is the point of having the insurance and the tax work in one office.

If your final income lands below the poverty line (the year went worse than expected, hours were cut, the work did not come), you generally keep the credit and repay nothing, provided the original estimate was made in good faith.

This matters most for lawfully present immigrants inside Medicaid's five-year waiting period, who have nothing to fall back on if the credit is clawed back. It does not cover an estimate made with reckless disregard for the facts.

Income coming in lower than you estimated usually produces extra credit at filing rather than a bill.
