The University of California's mileage reimbursement rates for expenses incurred in connection with the business use of a private automobile will increase in accordance with the Internal Revenue Service standard mileage rates published in IRS Notice 2023-03. The following new rates are effective for expenses incurred on or after January 1, 2023:

• The reimbursement rate for the use of a private automobile for University business travel will increase from 62.5 cents a mile to 65.5 cents a mile.
• The reimbursement rate for driving an automobile in connection with a move or relocation will remain the same at 22 cents a mile. (Note that reimbursements for moving-related expenses, including mileage, are considered taxable wage income as of January 1, 2018).

As a public agency, University employees traveling on official business should observe normally accepted standards of propriety in the type and manner of expenses they incur and avoid any expenditure that would appear extravagant or lavish under the circumstances.
