The optional standard mileage rates for use of a vehicle have gone down by one-half cent per mile for 2014 (Notice 2013-80). Taxpayers can use the optional standard mileage rates to calculate the deductible costs of operating an automobile.
For business use of a car, van, pickup truck, or panel truck, the 2014 rate is 56 cents per mile. Driving for medical or moving purposes may be deducted at 23.5 cents per mile. Both rates are one-half cent lower than for 2013.
The rate for service to a charitable organization is unchanged, set by statute (Sec. 170(i)) at 14 cents a mile.
The portion of the business standard mileage rate that is treated as depreciation is 22 cents per mile for 2014, down one cent from the 23 cent rate in effect in 2012 and 2013.
For purposes of computing the allowance under a fixed and variable rate (FAVR) plan, the maximum standard automobile cost for 2014 is $28,200 for automobiles (not including trucks and vans) or $30,400 for trucks and vans, increases of $100 and $500, respectively, from 2013. Under a FAVR plan, a standard amount is deemed substantiated for an employer’s reimbursement to employees for expenses they incur in driving their vehicle in performing services as an employee for the employer.
