The 2026 Mileage Rate Has Already Moved Twice — Here's What That Means

Every January the IRS updates its standard mileage rate, and most drivers glance at the new figure, then forget about it for a year. That habit has left a lot of people behind in 2026. The rate has now moved twice — a January increase followed by a rare mid-year jump — and the gap between what businesses budgeted in December and what they actually owe has widened fast.

A rate that already moved twice this year

The headline figures for 2026 look simple enough on their own. From 1 January, the IRS set the business rate at 72.5 cents a mile, medical and qualifying moving mileage at 20.5 cents, and charitable mileage at 14 cents, according to the IRS's own announcement. Full detail on those original figures sits on our 2026 IRS standard mileage rate reference page.

Then, on 1 July, the IRS did something it has done only once before this decade: it changed the rate mid-year. The business rate rose again, to 76 cents a mile, with medical and moving mileage up to 23.5 cents. Charitable mileage stayed at 14 cents, because that figure is fixed by statute rather than set by the IRS. The trigger was fuel. Average petrol prices climbed by roughly 38% between early January and mid-July 2026, according to the Journal of Accountancy's reporting, and fuel is the single most volatile line in the cost-per-mile calculation. The last time the IRS made a similar off-cycle correction was 2022, also triggered by a fuel price spike.

Five years of rate history, one clear direction

Line up the numbers since 2022 and the pattern is hard to miss: the business rate has climbed in every single period, with two mid-year corrections layered on top of the usual annual updates.

Six rate changes in five years is not normal. Before 2022, the IRS hadn't adjusted mid-year since 2011. It has now done so twice in four years, both times because fuel costs moved faster than the annual review cycle could track.

Why the rate keeps climbing

The IRS doesn't set this figure by guesswork. It commissions an annual study of the fixed and variable costs of running a vehicle — fuel, insurance, depreciation, maintenance, tyres and repairs — carried out by Motus, the firm that also owns the old Runzheimer vehicle-cost consultancy. When any of those inputs move sharply, the rate follows, as it did in a statement from Motus marking the July change.

“A mid-year rate adjustment recognizes the changing costs that organizations and employees are facing. Keeping reimbursement rates aligned with current operating expenses helps to ensure that employees are fairly reimbursed and that business-driving costs are accurately reflected.”

— Phong Nguyen, CEO of Motus

Fuel is only part of the story. Insurance premiums, vehicle prices and repair costs have all trended upward over the past three years too, which is why the rate rose even in years without a fuel spike. The move from 62.5 to 65.5 cents in 2023 and to 67 cents in 2024 both happened without a mid-year correction, purely on the back of the annual cost review.

What a fast-rising rate costs a real sales team

Take a firm with eight travelling sales reps, each driving 1,400 miles a month for client visits — a fairly typical patch for a regional B2B sales role. That's 16,800 miles a year per rep, or 134,400 miles across the team.

In 2025, at a flat 70 cents a mile, that team cost $94,080 in mileage reimbursement. In 2026, with 72.5 cents for the first half of the year and 76 cents for the second, the blended rate works out at 74.25 cents a mile. The same 134,400 miles now costs $99,792 — $5,712 more, without a single extra mile driven or a single new client won.

Isolate just the mid-year jump and it still stings. If that team drives half its annual mileage in the second half of the year — 67,200 miles — the move from 72.5 to 76 cents alone adds $2,352 to the second-half travel budget. For a finance team that built its 2026 forecast in December 2025, that's an unbudgeted cost showing up in August and September expense reports. Any business that hasn't re-run its travel budget should do it with the mileage reimbursement calculator, and read our employer's guide to 2026 mileage reimbursement for how to apply the split rate cleanly through payroll.

Some employers are using the disruption as a prompt to look beyond a flat per-mile rate altogether. A Fixed and Variable Rate (FAVR) plan pays a monthly allowance plus a lower per-mile rate, tracking each employee's actual costs more closely — worth understanding before the next fuel spike forces another recalculation. Our guide to FAVR mileage reimbursement explains how it compares with the standard rate.

What it means for gig and self-employed drivers

Anyone claiming the standard mileage deduction — rideshare and delivery drivers, sole traders visiting clients, self-employed tradespeople — benefits directly from a higher rate, because it raises the value of every mile logged.

A driver who logs 20,000 business miles across 2026 can claim roughly $14,850 using the blended 74.25-cent rate, against $14,000 if 2025's flat 70-cent rate had carried on. That's $850 of extra deductible expense. At a 22% marginal federal tax rate, that's about $187 less tax owed, plus a further reduction in self-employment tax, since the deduction lowers net self-employment earnings too.

The catch is proof. The IRS only allows the higher rate if mileage is logged contemporaneously, with dates, purposes and odometer readings, and if drivers correctly split miles before and after 1 July. A single annual estimate won't hold up to scrutiny. Our guide to the mileage tax deduction for the self-employed covers exactly what a compliant log needs to include.

What to do now

For employers

• Re-run your 2026 travel budget using 72.5 cents for January to June and 76 cents for July to December, not a flat annual figure.
• Update payroll and expense software with the 1 July rate change so reimbursements after that date use 76 cents automatically.
• Recalculate reimbursement using our step-by-step mileage reimbursement guide so payroll applies split rates correctly.
• Check whether your mileage policy references "the IRS rate" by name — if so, confirm your system pulls the current figure rather than one hard-coded back in January.
• Compare a flat per-mile rate against a FAVR plan if your travelling headcount is large enough to justify tracking actual costs.

For self-employed and gig drivers

• Split your mileage log at 30 June 2026 so miles before and after that date use the correct rate.
• Log every trip as it happens — date, purpose, start and end odometer readings — rather than reconstructing months later.
• Compare the standard mileage method against actual expenses for your vehicle; a higher rate narrows the gap but doesn't always close it, especially for newer or more expensive vehicles.
• Treat the extra deduction as a lower tax bill, not spare cash — it only reduces what you owe when you file, not your bank balance today.

The direction of travel

Zoom out and the trend is unmistakable: six rate increases in five years, two of them unscheduled, and not a single cut. Fuel, insurance and vehicle prices show no sign of reversing, so treating 76 cents as a temporary spike looks optimistic. Employers who build next year's travel budget on the assumption that the rate only moves once, in January, are already behind. The safer planning assumption for 2027 is a further rise, not a plateau — and a small mid-year contingency line is starting to look less like caution and more like ordinary budgeting.
