What Is the Premium Tax Credit: Eligibility, Calculation, Reconciling

The premium tax credit is a refundable federal tax credit that lowers what you pay for health insurance bought through the Health Insurance Marketplace. For the 2026 tax year, you can qualify if your household income falls between 100% and 400% of the federal poverty level, roughly $15,960 to $63,840 for an individual, or $33,000 to $132,000 for a family of four.¹ Enhanced credits that had temporarily removed the upper income cap expired at the end of 2025, so the 400% ceiling matters again for anyone estimating 2026 eligibility.

Who Qualifies

To receive the credit, you must meet all of the following during at least one month of the year:²

You bought your health coverage through the federal or a state Marketplace. Plans purchased directly from an insurer outside the Marketplace don’t qualify, and catastrophic Marketplace plans are also ineligible.
Your household income is at least 100% but no more than 400% of the federal poverty level for your family size.³
You don’t have access to employer coverage that is both affordable and meets minimum value standards. For plan years beginning in 2026, employer coverage counts as affordable if your share of the premium for the lowest-cost self-only plan is no more than 9.96% of household income.⁴
You aren’t eligible for Medicare, Medicaid, CHIP, TRICARE, or other government-sponsored coverage that qualifies as minimum essential coverage.⁵
You don’t file as married filing separately, unless you qualify for the exception for victims of domestic abuse or spousal abandonment.
No one else can claim you as a dependent.

The government-program rule catches people off guard. Even if you choose not to enroll in Medicaid or Medicare, being eligible for those programs generally disqualifies you from the premium tax credit.⁶ Narrow exceptions exist. Some limited Medicaid coverage, such as coverage only for family planning or emergency services, does not count as minimum essential coverage and would not block your credit.

What Changed for 2026

From 2021 through 2025, temporary federal legislation eliminated the 400% income cap and lowered the share of income households were expected to contribute toward premiums. Those enhanced credits expired on December 31, 2025, and were not renewed.⁵ For 2026, that means:

Households above 400% of the federal poverty level no longer qualify for any credit.
The applicable percentages have reverted to higher pre-2021 levels, producing smaller credits in most income brackets.
Repayment caps for excess advance credits have been fully eliminated, so you could owe back the entire overpayment.

How the Credit Amount Is Calculated

Your credit is based on the gap between what you’re expected to contribute toward your premium and the cost of a reference plan in your area. The reference plan, called the benchmark plan, is the second-lowest-cost Silver plan available to you through the Marketplace.⁷ You don’t have to enroll in the benchmark plan to receive the credit. It simply sets the dollar figure used in the formula.

The IRS publishes an applicable percentage table each year that determines how much of your income you’re expected to pay. For 2026, the percentages range from 2.10% at the low end to 9.96% between 300% and 400% of the federal poverty level, scaling smoothly within each bracket.⁴ The credit equals the benchmark plan’s monthly premium minus your expected contribution. If the benchmark plan costs $600 per month and your expected contribution based on income is $200, your monthly credit is $400. Because benchmark premiums vary by location and age, two families with identical incomes in different parts of the country will typically receive different credit amounts.

How Household Income Is Measured

The credit uses modified adjusted gross income (MAGI), not just your wages. MAGI for this purpose equals your adjusted gross income plus three additions:⁸

Tax-exempt interest, such as income from municipal bonds
Nontaxable Social Security benefits
Foreign earned income excluded from your return

Household income includes the MAGI of everyone in your tax family: you, your spouse if filing jointly, and any dependents required to file their own return. This broader measure matters because nontaxable Social Security benefits, for example, can push your household income above the 400% threshold even though they don’t appear as taxable income on your return.

Taking the Credit in Advance or at Tax Time

You have two ways to use the premium tax credit. The more common option is to have the estimated credit paid in advance directly to your insurance company each month, lowering your premium bill in real time. This is called the advance premium tax credit, or APTC. When you complete your Marketplace application and enter your estimated income, the Marketplace calculates how much you qualify for and lets you choose how much of the credit to apply each month, from the full estimated amount down to zero.⁹

The second option is to pay full price for your Marketplace plan throughout the year and claim the entire credit as a lump sum when you file. Because the credit is refundable, it can increase your refund or be paid to you even if you owe no federal income tax. This route avoids any risk of overpayment but requires you to carry the full premium each month.

Many people split the difference, taking a portion of the credit in advance and claiming the rest at tax time. Using less than the full advance amount gives you a lower monthly premium while building in a cushion against having to repay excess credits if your income ends up higher than projected.

Reporting Changes During the Year

If you’re receiving advance payments, keeping the Marketplace informed matters. Your advance credit was calculated from the income and household size you estimated at enrollment, so any significant change can throw off the math and create a repayment obligation at tax time. Report:¹⁰

An increase or decrease in income
Adding or losing a household member through marriage, divorce, birth, or death
Gaining access to employer-sponsored coverage
Becoming eligible for Medicare or Medicaid

When you report a change, the Marketplace recalculates your advance credit for the remaining months. If your income rises, monthly payments drop to reduce the chance of overpayment. If income falls, payments increase so you get more help right away. Not reporting doesn’t pause your advance payments. It just makes the year-end reconciliation more likely to produce a surprise bill.

Claiming and Reconciling the Credit on Your Return

To claim or reconcile the premium tax credit, you need Form 1095-A, the Health Insurance Marketplace Statement. The Marketplace must send this form to you by January 31 of the year following coverage.¹¹ It shows your monthly enrolled premium, the benchmark plan premium, and any advance credit payments made to your insurer. If your form doesn’t arrive, is lost, or contains errors, you can download a copy through your HealthCare.gov or state Marketplace account. The HealthCare.gov tax tool can also look up the correct benchmark premium if that figure is wrong or missing.¹²

Regardless of whether you took advance payments, you must file Form 8962 (Premium Tax Credit) and attach it to your Form 1040 or 1040-SR. If advance payments were made on your behalf, filing is mandatory even if your income wouldn’t otherwise require you to file a return.¹³ On Form 8962, you transfer the monthly figures from Form 1095-A, enter your household income and family size, and calculate the credit you were actually entitled to based on your final numbers. The form then compares that amount to any advance payments. Three outcomes are possible:

Advance payments were less than your actual credit. You receive the difference as an additional refund or a reduction in your tax bill. This commonly happens when income drops or the family grows during the year.
Advance payments matched your actual credit. No adjustment is needed.
Advance payments exceeded your actual credit. You owe the excess back. This typically happens when income rose beyond what you estimated.

If you didn’t take advance payments, Form 8962 calculates your credit from scratch and adds it to your refund.¹⁴

What Happens If You Don’t File

Skipping your tax return after advance payments have been made on your behalf has real consequences. The IRS will block you from receiving future advance payments, meaning you’d owe the full cost of your Marketplace premium going forward.¹³ Filing your return and attaching Form 8962 restores your eligibility for advance credits in subsequent years.

Repaying Excess Advance Credits in 2026

For the 2026 tax year, the rules on repaying excess advance credits have changed. Previously, the amount you had to pay back was capped based on your income level. Starting with plan years beginning on or after January 1, 2026, those repayment caps no longer exist. If your advance payments exceed the credit you were entitled to, you must repay the full excess when you file.¹⁵ And if your income ends the year above 400% of the poverty level, you must repay every dollar of advance credit you received.⁵

The elimination of the caps makes accurate income estimation more important than before. If you expect your 2026 income to fluctuate, consider taking less than the full advance credit or reporting income changes to the Marketplace promptly. Any excess is added directly to your tax liability, which can shrink a refund or produce a balance due.

A Note for Self-Employed Filers

If you’re self-employed and buy Marketplace coverage, the premium tax credit interacts with the self-employed health insurance deduction in a way that needs care. Both reduce the cost of your premiums, but you can’t claim both for the same dollar. Because the deduction (reported on Schedule 1 using Form 7206) lowers your adjusted gross income, and a lower AGI can increase your credit, the two calculations become circular.¹⁶ The IRS addresses this through an iterative method described in Publication 974. Tax software generally handles it automatically. If you prepare your return by hand, Publication 974 walks through the process step by step.
