Utah Mileage Reimbursement 2026: A Computed State Rate

Most states either adopt the federal figure or set their own. Utah does something in between: the policy defines a state mileage rate as a calculated figure, rounded to the nearest tenth of a cent, based on the average of two federal rates. Those two are the full rate for a trip where a privately owned automobile is authorized or no government vehicle is available, and the reduced rate for a trip where a government vehicle is available.

Averaging the pair produces a figure well below the full federal rate and well above the reduced one, and it moves whenever either federal figure moves. The state is effectively paying one rate for both situations rather than asking a manager to decide which tier applies.

The definition is in the Division of Finance's policy 10-9, on the use of personal vehicles for state business. It defines a traveler widely, as anyone traveling on official state business for an agency or a political subdivision, and says the term includes employees, non-employees, board members, elected officials, vendors, volunteers, grant recipients and award beneficiaries.

The policy also defines the two federal rates it averages, by their own federal labels, so the arithmetic can be checked against the federal page rather than taken on trust. That is unusual: most state policies print a figure and leave the derivation out.

• The high mileage rate is the federal figure for a trip where a personal automobile is authorized.
• The second figure is the one for a trip where a government vehicle is available.
• The state rate is the average of the two, rounded to a tenth of a cent.

Utah keeps commute travel in a separate policy, 10-18, and that split matters more here than it does elsewhere. The state rate averages a reduced federal figure into every mile, so a trip that should never have been claimed at all costs the traveler more than a wrong tier would.

A reader checking a claim therefore needs both documents: policy 10-9 for what a business mile pays, and policy 10-18 for whether the mile was business in the first place.

Utah's computed rate is a state travel figure, and the state sets no private-employer rate. A private claim follows the written policy, and a policy that tracks the federal full rate pays 72.5 cents per mile through June 30, 2026 and 76 cents per mile from July 1 — considerably more than the state's average.

• Do not read the Utah figure as the federal rate rounded down: it is an average of two federal figures, and neither is the one a private policy usually names.
• Keep the travel date, because the average changed when the federal pair changed in July.
• Check the commute policy before a claim that starts or ends at home, since that is where the boundary is.

The Utah Division of Finance publishes these figures. State agencies, political subdivisions and the travelers they reimburse, including board members, volunteers and vendors on state business.

The figure is calculated, not adopted: policy 10-9 defines the state rate as the average of the two federal rates, rounded to the nearest tenth of a cent.

Because the average includes the reduced federal figure, the Utah rate sits far below the full federal rate a private policy usually names.

The IRS moved the business standard mileage rate mid-year, so a 2026 trip prices by its date. This is the benchmark an employer's rate method usually follows.

The IRS has not published a standard mileage rate for 2027. Until it does, two things decide what a trip pays: the year you drove it and the date within that year. A 2026 trip pays 72.5 cents per mile through June 30 and 76 cents per mile from July 1. Miles driven from January 1, 2027 will use whatever figure the IRS publishes next.

The next year's rate has arrived in December in each of the last nine years, between December 14 and December 31. An announcement is not always the last word. The IRS raised the 2026 figure on July 1, halfway through the year, so a 2027 claim may need two rate periods.

A state that publishes a rate for its own travelers follows its own calendar, so it can publish the next period before the IRS does. A private employer's rate changes when its own policy changes, or when the benchmark that policy follows moves. It does not change because the calendar year turns.
