Final answer:
The Correct option is 5). Katie should treat the receipt of the unrestricted partnership interest, valued at $25,000, as ordinary income in the current year.
Step-by-step explanation:
When Katie receives a 1/3 interest in the TR Partnership, which has a fair market value of $25,000, as compensation for her contribution to the firm's multimedia presentation expertise, this transaction is treated for tax purposes as compensation for services. Therefore, the partnership interest Katie received is not considered a carried interest, capital gain, or a nontaxable gift. Instead, it should be considered ordinary income for Katie because it is compensation for services. The value of the partnership interest that Katie has to report as income for the current tax year would be $25,000, in compliance with the Internal Revenue Service regulations.
