<prompt> Human: I drive my car up 30 miles a day for work. i get paid mileage reimbursement but wont get them for maintenance. How would I write them off on my taxes?Assistant: If you are getting mileage reimbursement, as tax free income, that is factored to cover maintenance.Are you self employed, or w2? Human: W-2. An employee I know wrote off his expenses and had no problems. I dont see why I cant do the same.  <response>: Two things. If you were reimbursed tax free money, you already wrote off that amount. Thats what a reimbursement is. Your employer paying you for the use of your vehicle. You dont pay taxes on that money.Second, in the past employees could write off expenses they incurred for their employer, that was NOT reimbursed. not the case here. That deduction has been suspended for the next 6 years though.
