Final answer:
Hank's gross income for the current year includes the $500 he received for handyman services, as he uses the cash method of accounting and is a calendar-year taxpayer.
Step-by-step explanation:
The subject of the question is Business, specifically focusing on accounting and taxation. The question asks to compute Hank's gross income for the current year under different transaction scenarios related to part-time handyman work. As Hank uses the cash method of accounting and is a calendar-year taxpayer, his gross income would include the $500 he received for his services in December of this year. With the cash method of accounting, income is recognized when cash is received, and expenses when they are paid. Therefore, any income Hank received this year for his services will be included in this year's gross income.
