Standard mileage rates decrease for 2017. The IRS announced that the optional mileage allowance for owned or leased autos, vans, pickups and panel trucks will go down by 0.5¢ to 53.5¢ a mile for business travel after 2016. The rate can also be used by employers to provide tax-free reimbursements to employees who drive their own autos under an accountable plan and to value personal use of certain low-cost employer-provided vehicles. The rate for using a car to get medical care or in connection with the moving expense deduction will decrease by 2¢ to 17¢ a mile.
