Final answer:
Employees deduct business expenses on tax forms such as the 1040 tax form and the Schedule C form.
Step-by-step explanation:
Employees deduct business expenses on their tax forms, such as the 1040 tax form for individual income tax and the Schedule C form for business income (if they are self-employed). The 1040 tax form is used to report personal income and deductions, including unreimbursed business expenses for employees. On the other hand, the Schedule C form is used by self-employed individuals to report business income and expenses.
