The Internal Revenue Service (IRS) has changed the standard mileage rate for calculating the amount per mile they will allow you to deduct for driving for business purposes in 2009. They have been lowered from the last half of 2008 due to a decline in gas prices.
2009 IRS Mileage Rates
- Business Driving: 55 cents per mile
- Driving for Medical or Moving Purposes: 24 cents per mile
- Driving for Charity: 14 cents per mile
This rate includes the costs of gasoline, maintenance, and depreciation. You can find out more about how to calculate depreciation on your vehicles by accessing IRS Publication 946.
