The Internal Revenue Service announced an increase in the optional standard mileage rate for the final 6 months of 2022. Taxpayers may use the optional standard mileage rates to calculate the deductible costs of operating an automobile for business and certain other purposes.

For the final 6 months of 2022, the standard mileage rate for business travel will be 62.5 cents per mile, up 4 cents from the rate effective at the start of the year. The new rate for deductible medical or moving expenses (available for active-duty members of the military) will be 22 cents for the remainder of 2022, up 4 cents from the rate effective at the start of 2022. These new rates become effective July 1, 2022.

In recognition of recent gasoline price increases, the IRS made this special adjustment for the final months of 2022. The IRS normally updates the mileage rates once a year in the fall for the next calendar year. “The IRS is adjusting the standard mileage rates to better reflect the recent increase in fuel prices,” said IRS Commissioner Chuck Rettig. “We are aware a number of unusual factors have come into play involving fuel costs, and we are taking this special step to help taxpayers, businesses and others who use this rate.”

Midyear increases in the optional mileage rates are rare, the last time the IRS made such an increase was in 2011.
