Under current Federal law allowable deductions for charitable contributions of vehicles boats and airplanes (collectively referred to as assets in this summary) for which the claimed value exceeds $500 will depend how the asset is used by the recipient charity. If the organization sells the asset without any significant intervening use or material improvement the donors deduction is limited to the gross sales proceeds received by the charity. But if the organization uses the asset in direct furtherance of its charitable purpose the donor may deduct the fair market value of the asset. (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 willing seller would agree upon if neither were pressured to do so.
