The premium tax credit (PTC) is a refundable credit that is available to certain individuals “whose household income for the taxable year equals or exceeds 100%, but does not exceed 400% of an amount equal to the poverty line for a family of the size involved.” In other words, it’s a refundable tax credit that specifically subsidizes the cost of insurance purchased on a health care marketplace for individuals who are over the federal poverty level (FPL), but not by 400 percent or more.
This credit is available as an advance paid directly to the marketplace for qualifying taxpayers who cannot afford (or do not wish) to pay their full monthly premium out of pocket. The amount of the credit is calculated based on estimated annual household income.
When taxpayers receive more advance credit than they are entitled to, they must repay the excess. So, the consequences for an intentional or inadvertent underestimation of annual income can be severe. What follows is an overview of how the credit works and describes strategies for reducing the amount of advance premium tax credit (APTC) the taxpayer must repay both immediately and after the fact.
