Answer:
a. Cash basis
This recognizes revenue and expenses only when cash been received or spent.
Gross income for 2013 = Cash received for medical services + Advance payment
= 280,000 + 12,000
= $292,000
b. Accrual basis
This recognizes only revenue and expenses incurred in a period, regardless of if cash is paid or not.
Gross income for 2013 = Cash received for medical services - Cash received for medical services provided in previous periods + Accounts receivable
= 280,000 - 40,000 + 60,000
= $300,000
c. Use CASH BASIS OF ACCOUNTING
From a taxation point of view, using the cash basis would be more beneficial as Al will pay a less amount of tax as it is a lower income.
He will also be sure of the cash received unlike Accrual that recognizes Accounts receivable which have a chance of not being collected.
