What is the IRS mileage rate for use of a car for business in 2013?
The optional standard rate allowed by the Internal Revenue Service for the business use of a car in the year 2013 is 56.5 cents per mile. (This is 1 cent higher than the rate allowed in the year 2012.)
In addition to the 56.5 cents per mile, you are also allowed to claim an expense for parking fees and tolls that are associated with the business use of your car.
The optional standard rate has some restrictions such as the number of vehicles used at one time and the prior use of Section 179 depreciation.
An alternative to the optional standard rate per mile is to compute the business portion of the actual expenses for gasoline, repairs, insurance, depreciation, licenses, etc.
