Mileage Tax Deduction Rises With Gas Prices

If you are able to write off vehicle mileage for business or medical visits, the rate at which you can write off those miles is going up. The move is sure to be welcomed by taxpayers, but will create a bit more work for tax preparers.

The Internal Revenue Service (IRS) has announced an increase in the optional standard mileage rates for the final six months of 2011. The rate will increase to 55.5 cents a mile for all business miles driven from July 1, 2011, through Dec. 31, 2011. This is an increase of 4.5 cents from the 51 cent rate in effect for the first six months of 2011.

"This year's increased gas prices are having a major impact on individual Americans. The IRS is adjusting the standard mileage rates to better reflect the recent increase in gas prices," said IRS Commissioner Doug Shulman. "We are taking this step so the reimbursement rate will be fair to taxpayers."

Other costs

While gasoline is a significant factor in the mileage figure, the IRS says other items enter into the calculation of mileage rates, such as depreciation and insurance and other fixed and variable costs.

The optional business standard mileage rate is used to compute the deductible costs of operating an automobile for business use in lieu of tracking actual costs. This rate is also used as a benchmark by the federal government and many businesses to reimburse their employees for mileage.

The new six-month rate for computing deductible medical or moving expenses will also increase by 4.5 cents to 23.5 cents a mile, up from 19 cents for the first six months of 2011. The rate for providing services for charitable organizations is set by statute, not the IRS, and remains at 14 cents a mile.

Taxpayers always have the option of calculating the actual costs of using their vehicle rather than using the standard mileage rates.
