The IRS has announced the 2013 standard mileage rate to use in computing the deductible costs of operating an automobile for business use. Employers often use the rate to determine how much they will pay employees for using their personal vehicles for work-related purposes.
The 2013 rate for transportation or travel expenses is 56.5 cents per mile for all miles of business use. For more information, go to http://www.irs.gov/uac/2013-Standard-Mileage-Rates-Up-1-Cent-per-Mile-for-Business,-Medical-and-Moving.
