Beginning on January 1, 2018, the standard mileage rates for the use of a car, van, pickup or panel truck are:

• 54.5 cents for every mile of business travel driven, up 1 cent from the rate for 2017.
• 18 cents per mile driven for medical or moving purposes, up 1 cent from the rate for 2017.
• 14 cents per mile driven in service of charitable organizations.

The business mileage rate and the medical and moving expense rates each increased 1 cent per mile from the rates for 2017. The charitable rate is set by statute and remains unchanged.

The standard mileage rate for business is based on an annual study of the fixed and variable costs of operating an automobile, including depreciation, insurance, repairs, tires, maintenance, gas, and oil. The rate for medical and moving purposes is based on the variable costs, such as gas and oil. The charitable rate is set by law.

These optional standard mileage rates are used to calculate the deductible costs of operating an automobile for business, charitable, medical or moving purposes.

Taxpayers always have the option of claiming deductions based on the actual costs of using a vehicle rather than the standard mileage rates.

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 more than four vehicles used simultaneously. Please call if you need additional information about these and other special rules.

In addition, basis reduction amounts for those choosing the business standard mileage rate, as well as the maximum standard automobile cost that may be used in computing an allowance under a fixed and variable rate plan and the maximum standard automobile cost that may be used in computing the allowance under a fixed and variable rate (FAVR) Plan were also announced by the IRS.
