What is IRS mileage rate for use of a car for business?
The standard rate allowed by the Internal Revenue Service for the business use of an automobile in the year 2010 is 50 cents per mile. (This is lower than the rate allowed in the year 2009.) In addition to the standard rate of 50 cents per mile, you are also allowed to claim an expense for parking fees and tolls associated with the business use of your car.
An alternative to the standard rate per mile is to compute the business portion of the actual expenses for gasoline, repairs, insurance, depreciation, licenses, etc.
