If you are an independent contractor then you can prepare a Schedule C to enter your business expenses like mileage. And if you use online TurboTax you will need to use Self-Employed. If you are self-employed post back for further help with self-employment income.
@mirandablasingam but if you are a W-2 employee, there is no tax break available.....
I could have sworn I replied to this exact post earlier with this information:
Sorry---W-2 employees cannot deduct job-related expenses on a federal return. Job-related expenses were eliminated as a federal deduction for W-2 employees by the tax laws that changed for 2018 and beyond. Your state tax laws might be different in AL, AR, CA, HI, MN, NY or PA.
