As an employee, you may be able to deduct certain unreimbursed expenses that the IRS considers "ordinary and necessary" to do your job. That would include things like:
- Union dues
- Dues or subscriptions to professional societies
- Travel and meals for business, including DOT per diem
- Home office
- Excess educator expenses
- Education that either maintains or improves job skills or is required to keep your salary or job
However, employees can't deduct mileage or commuting costs between their home and main workplace.
Job-related expenses aren't fully deductible as they're subject to the 2% rule.
