1. Ordinary and Necessary. You can only deduct unreimbursed expenses that are ordinary and necessary to your work as an employee. An ordinary expense is one that is common and accepted in your industry. A necessary expense is one that is appropriate and helpful to your business.
2. Expense Examples. Some costs that you may be able to deduct include:
- Required work clothes or uniforms not appropriate for everyday use.
- Supplies and tools you use on the job.
- Business use of your car.
- Business meals and entertainment.
- Business travel away from home.
- Business use of your home.
- Work-related education.
3. Forms to Use. In most cases, you report your expenses on Form 2106 or Form 2106-EZ. After you figure your allowable expenses, you then list the total on Schedule A as a miscellaneous deduction.
4. Educator Expenses. If you are a K-12 teacher, you may be able to deduct up to $250 of certain expenses you paid in 2015. These may include books, supplies, equipment and other materials used in the classroom. You claim this deduction as an adjustment on your return, rather than an itemized deduction.
