The Premium Tax Credit is a refundable tax credit in the United States designed to help eligible individuals and families with low or moderate income afford health insurance purchased through the Health Insurance Marketplace. To qualify for the credit, you must meet certain requirements. Your premium tax credit amount is based on a sliding scale, depending on your income. If your income is near the lower end of the scale, you’ll qualify for a larger credit. Conversely, if your income is near the upper end of the scale, you’ll qualify for a smaller credit.
