For more details see Moving Expenses for Members of the Armed Forces.
Taxpayers always have the option of calculating the actual of using their vehicle rather than using the standard mileage rates.
Taxpayers can use the standard mileage rate but must opt to use it in the first year the car is available for business use. Then, in later years, they can choose either the standard mileage rate or actual expenses. Leased vehicles must use the standard mileage rate method for the entire lease period (including renewals) if the standard mileage rate is chosen.
A taxpayer may not use the business standard mileage rate for a vehicle after using any depreciation method under the Modified Accelerated Cost Recovery System (MACRS) or after claiming a Section 179 deduction for that vehicle. In addition, the business standard mileage rate cannot be used for any vehicle used for hire or for more than four vehicles used simultaneously.
