As an employee, you may be able to deduct certain unreimbursed expenses that the IRS considers "ordinary and necessary" to do your job. Job-related expenses aren't fully deductible as they're subject to the 2% rule.

In taxes, the 2% rule refers to the limitation on certain types of miscellaneous deductions, including unreimbursed job-related expenses (Form 2106), tax preparation fees, investment or advisory fees, and safe deposit box rentals.

Under the 2% rule, you're only allowed to deduct the portion of miscellaneous expenses that exceeds 2% of your adjusted gross income (AGI). You must also itemize to get this deduction (Schedule A).
