Final answer:
The $10,000 payment is included in gross income; the basis for the property is reduced by $10,000.
Step-by-step explanation:
The $10,000 payment for the utility easement along Hilary's property will be included in her gross income for the year. This is because any income received is generally considered as taxable according to the US federal tax code. On the other hand, the basis of the property will be reduced by $10,000 due to the easement. This means that the adjusted basis for the property will now be $200,000 - $10,000 = $190,000.
