The IRS bumped the business mileage rate from 72.5 cents to 76 cents per mile for travel on or after July 1, 2026. Medical and moving rates rose from 20.5 cents to 23.5 cents. The charitable rate stays put at 14 cents, where it has been stuck since 1998.
The trigger was fuel prices. When the IRS set the original 2026 rates back in December, gas was averaging about $2.89 per gallon nationally. By mid-July 2026, AAA reported the average had climbed to roughly $3.87, an increase of 34 percent. Much of that spike traces back to the war in Iran and uncertainty around oil production and shipping through the Strait of Hormuz.
The last time the IRS made a midyear adjustment was 2022, after Russia invaded Ukraine and gas prices surged past $5 per gallon in some markets.
This creates a split year for mileage calculations. Miles driven from January 1 through June 30 use the original rates. Miles driven on or after July 1 use the revised rates. If you drove 4,000 medical miles before July and another 4,000 after, you would calculate them separately: $820 for the first half at 20.5 cents, $940 for the second half at 23.5 cents.
The same logic applies to employer reimbursements. The new rates kick in only when both the expense and the reimbursement occur on or after July 1. Employers running accountable plans should review their policies to make sure they are applying the correct rate based on when the travel happened and when the payment goes out.
The business rate is higher because it accounts for both fixed and variable costs of operating a vehicle: depreciation, insurance, maintenance, tires, gas and oil. Medical and moving rates cover only variable costs, which is why they sit lower.
The charitable rate is a different animal entirely. Congress set it by statute, and it has not budged in nearly three decades. Adjusted for inflation, 14 cents from 1998 would be closer to 29 cents today.
Here is where it gets narrower than many taxpayers expect. The Tax Cuts and Jobs Act eliminated the deduction for unreimbursed employee business expenses starting in 2018, and the One Big Beautiful Bill Act made that change permanent. Most employees cannot write off business mileage whether their employer reimburses them or not.
Moving expense deductions are similarly limited. Only active duty military members moving under orders for a permanent change of station qualify, along with certain intelligence community members under rules effective for 2026.
Charitable mileage requires itemizing, which means it only helps if your total deductions exceed the standard deduction of $16,100 for single filers or $32,200 for married couples filing jointly. Many taxpayers skip it.
Self-employed individuals and business owners get the most benefit from the business rate since they can still deduct qualifying mileage on Schedule C.
Normally, tracking mileage means logging dates, destinations, miles driven, and business purpose. This year, you also need to note which side of July 1 the expense falls on. A mileage app can help, but a notebook or spreadsheet works, too.
If you use a vehicle exclusively for business, beginning and end-of-year odometer readings establish total mileage. Photos can serve as backup. If you mix business and personal use, your records need to clearly separate the two.
Gas prices forced the IRS’s hand, and now 2026 has two mileage rate regimes. The math is not complicated, but the documentation requirements are tighter than usual. Know when your miles were driven, keep clean records and make sure your employer’s reimbursement policies reflect the July 1 cutoff. The details matter this year more than most.
