Deductions & credits

Are you an employee?  If so, these expenses are not deductible on your federal return.  Depending on which state you live in, they may be deductible as itemized expenses.  You would still enter them in the Federal Section under Deductions and Credits >>Employment Expenses to include them as itemized expenses on returns such as CA or NY.

If you are self-employed or receive a 1099, then this would be considered a business expense.
