The U.S. Internal Revenue Service set the 2011 standard rate
for deducting business use of a car at 51 cents per mile, up from the current
rate of 50 cents.
The rate is based on an annual study, conducted by
Runzheimer International, of "fixed and variable costs of operating an
automobile," according to an IRS statement. "Taxpayers always have
the option of calculating the actual costs of using their vehicle rather than
using the standard mileage rates."
