Under the cash method of business accounting, income is charged to the year it is collected, while under the accrual method, income is assigned to the year it is earned.
Step-by-step explanation:
The major difference between the cash method of business accounting and the accrual method of business accounting is that under the cash method, income is recognized or charged to the year in which it is collected.
