• 51 cents per mile for business miles driven
• 19 cents per mile driven for medical or moving purposes
• 14 cents per mile driven in service of charitable organizations

The standard mileage rate for business is based on an annual study of the fixed and variable costs of operating an automobile. The rate for medical and moving purposes is based on the variable costs as determined by the same study. Independent contractor Runzheimer International conducted the study.
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. The IRS is requesting public comments on whether taxpayers should be allowed to use the business standard mileage rate in this circumstance.
Beginning in 2011, a taxpayer may use the business standard mileage rate for vehicles used for hire, such as taxicabs.
Also beginning in 2011, the standard mileage rates are announced in a separate notice, which also provides the amount a taxpayer must use in calculating reductions to basis for depreciation taken under the business standard mileage rate and the maximum standard automobile cost for automobiles under a FAVR allowance. The IRS plans to discontinue publishing the standard mileage rate revenue procedure annually but will publish modifications as required.
Taxpayers always have the option of calculating the actual costs of using their vehicle rather than using the standard mileage rates.
