In general, premium tax credits are available to people who buy marketplace coverage and whose household income is between 100 percent and 400 percent of the federal poverty level. (26 C.F.R. § 1.36B-2(b)). However, the American Rescue Plan Act of 2021increases the premium tax credits available for marketplace enrollees for plan years 2021 and 2022. Under the new premium tax credit schedule, families with incomes between 100 and 150 percent of the federal poverty level could have their premium contribution reduced to $0. Families with incomes over 400 percent of the federal poverty level would have their premium contribution capped at 8.5 percent of their household income.
