Mileage expense incurred for use of personal auto while on university business, i.e., intercampus travel, will be reimbursed at the allowable federal rate as per IRS regulations. Travel on non-business days, such as weekends and holidays, is fully eligible for mileage reimbursement. Mileage is typically calculated from the point of the office, or a net of the total miles driven less the normal round trip daily commute to work for that day.
The Internal Revenue Service has issued the 2023 optional standard mileage rates used to calculate the deductible costs of operating an automobile for business, charitable, medical or moving purposes.
Beginning on January 1, 2023, the standard mileage rates for the use of a car (also vans, pickups or panel trucks) will be:
- 65.5 cents per mile driven for business use, up 3 cents from the midyear increase setting the rate for the second half of 2022.
- 22 cents per mile driven for medical or moving purposes for qualified active-duty members of the Armed Forces, consistent with the increased midyear rate set for the second half of 2022.
- 14 cents per mile driven in service of charitable organizations; the rate is set by statute and remains unchanged from 2022.
These rates apply to electric and hybrid-electric automobiles, as well as gasoline and diesel-powered vehicles.
The rate is intended to cover the cost of operating a personal vehicle for business purposes, and as such, is formulated to take into account the estimated price of gas, automobile insurance and wear-and-tear. When using a Tufts owned or rental vehicle the above rates do not apply. You must purchase gas and submit receipts for reimbursement.
