Final answer:
Partiers Unlimited should deduct $450 as a business travel expense and report the other $450 as compensation for the employee's spouse's attendance, totaling $900 on the books.
Step-by-step explanation:
The question is about how Partiers Unlimited should deduct expenses related to an employee attending an association meeting with a spouse. The company reimbursed the employee for airfare, food, and lodging, totaling $450, and also included this amount as compensation on the employee's W-2. The correct deduction for Partiers would be Option C: $450 as travel expense and $450 as compensation. This is because the employee's expenses are legitimate business expenses, while the spouse's expenses would be considered additional compensation to the employee. Therefore, the company should deduct $450 as a travel expense and the other $450 that was reimbursed for the spouse's expenses should be reported as compensation to the employee.
