Can you claim PTC for only part of the year?

Calculate the premium tax credit by eligible month when Marketplace coverage or other health coverage changes midyear.

Ruling
Yes. For 2026, PTC can be claimed for only the months that satisfy the coverage-month rules. Full-year household income determines the annual FPL percentage, but enrollment, premium payment, and other coverage are tested month by month.

Keep annual income and monthly eligibility separate

Form 8962 uses the tax household's full-calendar-year income to determine FPL percentage and the contribution calculation. It then applies coverage facts by month when enrollment or eligibility changes. Starting Marketplace coverage late, ending it early, or becoming eligible for other minimum essential coverage does not convert the income test into a partial-year income test.

Count only valid coverage months

For each month, verify qualified Marketplace enrollment on the first day, required premium payment, and no disqualifying employer or government coverage for the full month. Birth, adoption, foster placement, and certain court orders have specific first-day exceptions. Enter each valid month on its Form 8962 row instead of spreading a partial-year total across twelve months.

Part-year example and errors

A taxpayer has Marketplace coverage from January through April, then affordable employer benefits begin in May. The first four months can produce PTC if all other rules are met; May through December do not. Using only income earned before May is wrong, as is claiming eight extra months because the final return reports one annual household-income figure.

Pair one annual income test with monthly coverage tests

Determine household income and family size for the entire tax year, then create a twelve-month coverage calendar for each person. Mark Marketplace enrollment, premium payment, and eligibility for employer or government coverage. Calculate PTC only on the rows that remain valid; do not prorate annual income or infer eligible months from the annual Form 1095-A total.

Keep the coverage calendar with the return so each zero and nonzero month can be tied to enrollment, payment, and other-coverage evidence.

Twelve-month coverage review

  • Use full-year household income on Form 8962 Part I.
  • Verify other-coverage start and end dates by person.
  • Enter only eligible Marketplace months in the monthly calculation.
