You may be able to deduct your unreimbursed business expenses as miscellaneous itemized deductions subject to the 2% adjusted gross income floor. You can't deduct the cost of any item for which you would have been reimbursed if you'd asked for the reimbursement. Your employer will not include in your wages reimbursement for your expenses paid under an accountable plan. You cannot deduct these expenses. But if the reimbursement is paid under a non-accountable plan, the reimbursement will be included in your wages and you deduct the expenses as miscellaneous itemized deductions subject to the 2% adjusted gross income floor.
If you pay out of pocket for job-related expenses, you may be able to deduct them on your return. In general, tax-deductible job expenses must be ordinary and necessary.

An expense does not have to be required to be considered necessary.
