Premium Tax Credit Repayment Calculator

How the squaring-up works

The premium tax credit is calculated on your actual income for the year, but it is paid to your insurer monthly during the year on the strength of an estimate you gave the Marketplace before it started. Form 8962 reconciles the two. If you received more than you turned out to be entitled to, the excess is added to your tax bill on Schedule 2. If you received less, the balance comes back as a refundable credit.

The three numbers you need are all on Form 1095-A, which your Marketplace sends in January: column A is what your plan cost, column B is the benchmark silver plan the credit is measured against, and column C is the advance credit actually paid on your behalf. Filing without reconciling is not optional — if you received any advance credit you must file Form 8962, and failing to do so can block future advance payments.

The change almost nobody reported

Through 2025 there was a safety net. If your income came in higher than you predicted but stayed under 400% of the federal poverty line, the amount you had to repay was capped by statute — a few hundred dollars at lower incomes, a few thousand at the top of the range. It existed precisely because Congress recognised that people cannot forecast their own income perfectly.

OBBBA removed those caps for tax years beginning after 31 December 2025. There is no cap at all now. You repay the full amount by which the advance payments exceeded your actual entitlement, however large, however honest the original estimate.

The calculator shows both figures side by side, so you can see exactly what the change costs in your case. For a freelancer who has a strong year, the difference between the old cap and the new uncapped amount routinely runs into thousands of dollars.

And if you crossed the cliff, all of it

The caps were never the main risk. The bigger one is that the 400% cliff came back for 2026. If your actual income lands above 400% of the poverty line you were not entitled to any credit — so the entire year's advance payments are repayable, in a single lump, with your return.

For a household of two in the lower 48 that line sits at $84,600. A freelancer who estimated $80,000, had an unexpectedly good autumn and finished at $86,000 does not repay a slice proportionate to the overshoot. They repay everything — which on a mid-priced plan for two adults can be well over $10,000 on a $6,000 surprise. The chart above shows the shape: a gentle slope, then a wall.

The one lever left once the year has ended

Here is the part that makes this worth calculating rather than dreading, and it is specific to the self-employed.

The income Form 8962 measures is modified adjusted gross income — and a deductible retirement contribution reduces it after the calendar year has closed. A SEP-IRA or Solo 401(k) contribution can generally be made up to your filing deadline including extensions; a traditional IRA contribution up to the April deadline. Either one lowers the income the reconciliation is measured against.

So if you finished the year just over the cliff, you have not yet lost. A contribution large enough to bring you back under the line restores your entitlement to the whole credit, which means it does not merely save tax at your marginal rate — it cancels the entire clawback. The calculator sizes that contribution and shows what it saves. It is the single most valuable thing a freelancer can do between January and April, and it disappears the moment you file.

An employee in the same position has almost nothing available, because a 401(k) deferral has to be made through payroll during the year. This is a genuine structural advantage of self-employment, and it is invisible on every reconciliation tool we could find.

A rule that runs the other way

One protection does survive, and it matters in a bad year rather than a good one. If your actual income comes in below 100% of the federal poverty line, you would normally not be an applicable taxpayer at all — which sounds like it should mean repaying everything. It does not. Provided the Marketplace estimated at enrolment that you would be at or above 100% and paid advance credit on that basis, the Form 8962 instructions still treat you as an applicable taxpayer. A collapsed year does not turn into a full clawback. The calculator flags this when it applies.

The exception to the exception is worth knowing: the protection is lost if you gave the Marketplace incorrect information with intentional or reckless disregard for the facts. An honest estimate that turned out wrong is fine. A convenient one is not.

What to do differently next year

The practical conclusion has reversed. With the caps gone, overestimating your income is now the cheaper mistake. Estimate high and you receive less advance credit during the year and claim the balance as a refund when you file — you have lent the government a few months of money. Estimate low and you owe a lump sum in April with no ceiling on it.

Two habits follow. Update your Marketplace application when your income picture changes rather than waiting for renewal; the adjustment applies to the remaining months and shrinks the eventual gap. And keep the cliff figure visible in November and December, when deferring an invoice into January or bringing a purchase forward still changes the answer. Our quarterly tax calculator and retirement plan calculator work on the same income figure, so it is worth setting all three against the same projection.

What this calculator does not cover

It uses the annual method, treating your benchmark and plan premiums as level across the months you were covered. If your household or plan changed mid-year, Form 8962 requires the monthly method and the figures will differ. It also does not handle the alternative calculation for a year of marriage, shared policy allocations between tax households, or state-level subsidy programmes that sit on top of the federal credit.
