On December 27, 2015, Roberta purchased four tickets to a charity ball sponsored by the city of San Diego for the benefit of underprivileged children. Each ticket cost $200 and had a fair market value of $35. On the same day as the purchase, Roberta gave the tickets to the minister of her church for personal use by his family. At the time of the gift of the tickets, Roberta pledged $4,000 to the building fund of her church. The pledge was satisfied by a check dated December 31, 2015, but not mailed until January 3, 2016.
a. Presuming that Roberta is a cash basis and calendar year taxpayer, how much can she deduct as a charitable contribution for 2015?
b. Would the amount of the deduction be any different if Roberta was an accrual basis taxpayer? Explain.
