Texas State’s maximum mileage reimbursement rate for travel which occurred between January 1, 2020 and December 31, 2020 was 57.5 cents per mile.

Travelers may use their personally owned vehicle for business purposes if it is more cost effective than renting a car, taking a taxi, other alternative transportation methods, or if it saves time. Those authorized to travel via a personally owned vehicle shall be reimbursed for mileage based on the current standard reimbursement rate approved by Cabinet. Mileage shall be calculated from the traveler’s designated headquarters to duty point or common carrier and back to designated headquarters.

Coordination of travel when two or more employees are traveling to the same duty point is encouraged.

Designated Headquarters

Designated headquarters is the location of the traveler's permanent work assignment. Designated headquarters other than San Marcos or Round Rock must be approved by the Vice President of Finance & Support Services. Working remotely from home does not change your designated headquarters.

Calculating Mileage

The reimbursement rate is directly tied to the dates of travel.

Texas State travelers requesting mileage reimbursement may select the following options for calculating mileage:

  • Vehicle odometer readings, or

  • MapQuest.

The documentation supporting the mileage expense must be attached for reimbursement.

MapQuest Chart

The Travel Office has created a MapQuest Chart with the allowed mileage for travel between commonly used travel destinations within Central Texas.  Rather than attaching the MapQuest print out for these, the Traveler may simply refer to the chart, use the miles/amount calculated and reference the MapQuest Number on the expense reimbursement report.  This will eliminate the need to print, scan, and attach the documentation when traveling to these locations. Note: the amount does not include the amount of any tolls paid. Those are listed separately on the expense report and the required documentation must be attached to support the expense amount.

Basic Information

  1. The mileage rate takes into account all actual automobile expenses such as fuel and lubrication, towing charges, repairs, replacements, tires, depreciation, insurance, etc. These and other automobile expenses will not be reimbursed when a personally owned vehicle is used.
  2. Parking and toll expenses will be reimbursed when properly documented on the travel reimbursement. Receipts are the prime form of documentation, but you may also use the TxTag Toll Calculator.
  3. When two or more persons on university business share a personally owned vehicle, only the driver may claim reimbursement for mileage.
  4. Expenses for travel between the traveler’s residence and headquarters (commuting expense) shall not be reimbursed.

Common Carrier

When a traveler is authorized to drive a personally owned vehicle to or from a common carrier terminal, mileage may be reimbursed as follows:
  • One round trip, including parking for the duration of the trip; or
  • Two round trips, including short-term parking expenses, when a traveler is driven to a common carrier.

Mileage in Lieu of Air Travel when Traveling Outside of Texas

A traveler may request mileage reimbursement for personal reasons even though air travel is the appropriate form of transportation if such costs shall not exceed the cost of airfare. The cost of airfare is based on the lower of the regular coach fare available, plus transportation costs to and from the airport and estimated parking fees incurred, had the traveler opted to use air travel. The traveler must obtain the regular coach fare from the university’s designated travel agency. The traveler should use the Airfare Equivalency Form provided on the university’s travel website to support the reimbursement amount.

Cost of Fuel Rate

Use "Regular Gasoline Retail Price" U.S. rate.

For your Trip Optimizer, choose the U.S. retail price provided by the U.S. Energy Information Administation's weekly fuel update.

Note:  The rate approved on your travel request will be the rate applied to the dates of travel on your expense report.
