Final answer:
The taxpayer should report $800 of income in 2016.
Step-by-step explanation:
For accrual basis taxpayer, income is reported when it is earned, regardless of when it is received. In this case, the taxpayer entered into a contract to provide termite inspection service each month for 36 months starting from January 1, 2015. The amount received for the contract was $2,400. To determine the amount of income to be reported in 2016, we need to calculate the portion of the contract that has been earned. Since the contract is for a total of 36 months and 12 months of service will be provided in 2016, the taxpayer should report $2,400 / 36 * 12 = $800 of income in 2016.
