Under the old rules, when you donated a vehicle to a charity, you could value the donation at the “fair market value.” This year, if you donate a vehicle to charity, you are limited to the sales price if the vehicle is sold, unless the charity uses the vehicle in its mission. If Charity Cars provides your vehicle to a struggling family, then you can still deduct the full “fair market value.” According to the IRS, the donor, not the recipient charity, must determine the “Fair market value” which the IRS describes as the price that a willing buyer and a willing seller would agree to if neither were pressured to do so.
