After decreasing two years in a row, the rate by which taxpayers may compute their deductions for costs of using an automobile for business purposes will go up to 58.5 cents per mile for the 2022 tax year, an increase of 2.5 cents per mile over the 2021 rate.

Notice 2022-03, in which the IRS announced the update on Friday, also provides the standard mileage rate for use of an automobile for purposes of obtaining medical care under Sec. 213, which will be 18 cents per mile, up 2 cents from 2021. The rate for providing services to a charitable organization remains the same, set by statute at 14 cents per mile (Sec. 170(i)).

The same rate as for medical care, 18 cents per mile, also applies to the deduction for moving and storage expenses under Sec. 217(g) by members of the armed forces on active duty who move pursuant to a military order and incident to a permanent change of station.

Taxpayers may use the business standard mileage rate for their use of an automobile as an ordinary and necessary business expense. Or they may claim actual allowable expense amounts if they substantiate the expenses, including by maintaining adequate records or other sufficient evidence.
