Mileage Rate

The mileage rate that may be claimed when using a privately owned vehicle for University Business is set by the New Mexico Per Diem and Mileage Act. 

Chrome River Expense is programmed to use the appropriate rate, based on the date the business miles were driven, using the “Mileage” sub-tile under the “Ground Travel” tile.  Departments may reduce the programmed rate to an appropriate amount due to their budgetary requirements, as needed.  To do so, select the “Mileage Override” sub-tile under the “Ground Travel” tile. 

Also, departments are reminded that employees who submit mileage logs to claim reimbursement for business miles driven in their personal vehicle should do so on a monthly basis.  Reimbursements submitted more than 60 days after the end of the month in which the miles were driven will be reported to Payroll to be included as additional taxable compensation to the employee.  The mileage log is available here:

The table below provides the “timely” submission dates for mileage logs:

For mileage reimbursement associated with new employee moving expenses, also use the “Mileage Override” sub-tile under the “Ground Travel” tile in Chrome River Expense.  The rate to enter for mileage driven in calendar year 2016 is $0.19 (nineteen cents) per mile, per IRS.  Also per the IRS for the calendar year 2017, the new mileage rate is $0.17 (seventeen cents) per mile.
