Final answer:
As a self-employed CPA, Carol can deduct $150 from her taxable income for the hockey tickets and dinner bill she purchased for her client.
Step-by-step explanation:
Carol, as a self-employed CPA, can deduct business expenses related to her work from her taxable income. In this scenario, the hockey tickets and the dinner bill at the restaurant can be considered as potential business expenses.
The hockey tickets, purchased for $180, can be deducted as an entertainment expense. However, there are limits and restrictions on the amount that can be deducted for entertainment expenses. In general, only 50% of entertainment expenses can be deducted. So, Carol can deduct 50% of $180, which is $90, as an entertainment expense.
As for the dinner bill of $120, Carol can deduct it as a business meal expense. Similar to entertainment expenses, there are also restrictions on the amount that can be deducted for business meals. Currently, the IRS allows a deduction of 50% of the business meal expenses. Therefore, Carol can deduct 50% of $120, which is $60, as a business meal expense.
To calculate the total deduction, we add the deductible amounts for the entertainment expense and the business meal expense: $90 + $60 = $150.
Therefore, Carol can deduct $150 from her taxable income.
