Answer:
Yes
Step-by-step explanation:
In this specific scenario yes, Kim does have to include the payment in gross income. This is because USA paid Kim a specific set amount for her services (leasing the building), this means that the 30,000 that Kim received are her earnings for providing such service and therefore must be included in the gross income. The only things that are exempt from this are state and municipal bonds interest anything else must be recorded/included
