Last year Acme paid Ralph $15,000 to install a new air-conditioning unit at its headquarters building. The air conditioner did not function properly, and this year Acme requested that Ralph return the payment. Because Ralph could not repair one critical part in the unit, he refunded the cost of the repair, $5,000, to Acme.
a. Is Ralph required to include the $15,000 payment he received last year in his gross income from last year?
b. What are the tax implications of the repayment if Ralph was in the 35 percent tax bracket when he received the $15,000 payment from Acme, but was in the 28 percent tax bracket when he refunded $5,000 to Acme?
c. How would you answer part b. if Ralph refunded $2,500 to Acme and not $5,000?
