The donor contributed appreciated securities within the time period of 1/1/2016 to 8/17/2021. The benefit of donating long-term appreciated securities, accounting for an additional $28,996 of charitable dollars, was calculated by assuming that the donor eliminated a 20 percent capital gains tax by contributing the securities, rather than selling them and donating the after-tax proceeds of the sale, resulting in charitable proceeds valued 20 percent higher than what the after-tax proceeds of a sale of the securities would have yielded. The actual benefit may have been higher or lower based on the specific tax situation of the donor and changes in the capital gains tax rate over the time period considered.
