Mileage Reimbursement

Audience:  All Employees who Travel on University Business

Last updated January 2026

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 2026 standard mileage rates used to calculate the deductible costs of operating an automobile for business purposes, which is 72.5 cents per mile.

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.
