This bill introduces a new refundable tax credit for individuals who sell their principal residence to a first-time homebuyer , aiming to make homeownership more accessible. The credit incentivizes sellers to assist with a first-time homebuyer's acquisition costs, such as down payments, inspection costs, and closing costs, which are defined as qualified home acquisition expenses . The credit amount for the seller is the lesser of the amount they paid for these qualified expenses or the tax reduction they would receive if the gain from their home sale was excluded from gross income. A first-time homebuyer is an individual who has not owned a principal residence in the two years prior to the sale. These provisions will apply to taxable years beginning after December 31, 2026.
