The premium tax credit is a government subsidy to help make health insurance premiums more affordable for middle and low-income people. The subsidy is only available to people with modified adjusted gross incomes from 100 to 400 percent of federal poverty level.
People who are eligible to receive a premium tax credit and have household incomes from 100% to 250% of poverty are eligible for cost-sharing subsidies.
