South Carolina Mileage Reimbursement 2026: No Number in the Code

Most states print a figure and revise it. The statute prints nothing to revise. Employer-paid reimbursements for mileage incurred in official duties must be paid at a per-mile rate equal to the standard business mileage rate established by the Internal Revenue Service, as that rate is periodically adjusted.

When the IRS raised the business rate, the South Carolina rate became 76 cents per mile on the same day, without a proclamation, an order or a new regulation. The statute has read that way since a 1999 act, and it has needed no amendment to keep up.

Regulation 19-101.10 supplies the term the statute leaves out. The mileage allowance paid for a privately owned vehicle is in lieu of all expenses connected with operating it, operating costs included, so a traveler cannot claim the allowance and a separate fuel or maintenance line for the same trip.

The same chapter also draws two lines a claimant needs: mileage between home and the regular place of employment is not reimbursable, and a trip that leaves from home is counted from the residence when the employee does not go by headquarters first.

The 2027 question needs no new South Carolina instrument, because the statute points at the rate the IRS adjusts. The 2027 figure will be whatever the IRS publishes, and the state rate will change on the same date.

A policy that adopts the federal rate can be rewritten between sessions. A statute has to be repealed to stop following the IRS.

The statute binds the State as an employer, not a private one. Title 41's Payment of Wages Act sets out what must be paid as wages, and read in full it says nothing about reimbursing an expense.

A private claim follows the employer's written policy. A policy that names the federal figure pays what the State pays its own staff, which is a choice the employer makes rather than a duty the code imposes on it.

• Read the statute as a description of the benchmark, not of a private obligation.
• Leave the home-to-work drive out of a claim, the way the regulation does.

The South Carolina Comptroller General publishes these figures. State officers and employees, whose mileage reimbursements the statute fixes at the federal business rate.

No state office sets these amounts. The statute defines the rate as the federal business rate, so the figures move when the IRS moves and the code prints no South Carolina number.

The travel regulation makes the allowance stand in place of every other expense of operating the vehicle, so a claim is one line rather than a set of receipts.

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.
