Yes, the federal government provides a premium tax credit on a sliding scale to individuals and families with low incomes. This reduces the amount of your premium, as long as you buy your plan through a health insurance exchange. You can use the tax credit as a discount on your premiums, or you can use it to get a refund when you file your taxes in the next year. If your income or family size changes, you may no longer be eligible for a tax credit, or you may be eligible for a tax credit if you were not previously eligible. You should make sure to consistently review and update this information.
