Starting July 1, 2026, the IRS has bumped up its standard mileage rates. If you’re putting your vehicle to use for business, medical trips, moving, or charity work, this change directly affects what you can deduct or get reimbursed for. It’s a good idea to update your mileage policy and accounting setup now rather than later, so you don’t miss anything with the old numbers.

What makes this update worth flagging is the timing. The IRS almost always sets these rates once a year, typically in December, for the full calendar year ahead. A change in the middle of the year is unusual, and it has surprised many business owners.

2026 IRS Standard Mileage Rate Comparison

Both the business rate and the medical/moving rate rose by 3.5 cents per mile starting July 1. The charitable rate held steady at 14¢, and it isn’t expected to move, since it’s set by statute rather than tied to the IRS’s annual cost review.

Why the IRS Made a Mid-Year Adjustment

There’s a fairly straightforward reason behind the timing. Fuel prices rose enough during the first half of 2026 that the rate set back in December no longer lined up with what it actually costs to run a vehicle. Since fuel is one of the larger variable costs baked into the business mileage rate, a big enough swing can push the IRS to issue a correction before the year is even over.

The practical effect is that a trip taken in May and a trip taken in August don’t get reimbursed at the same rate anymore, even though both fall in the same tax year. The rate that applies depends on when the mileage was actually driven, not on when someone files the expense report.

How the IRS Actually Calculates This Rate

It’s easy to assume this number is just picked somewhat arbitrarily, but there’s a real process behind it. Each year, the IRS hires an independent contractor to study the fixed and variable costs of owning and operating a vehicle in the U.S. That study is what produces both the business rate and the medical/moving rate.

The business rate factors in fixed costs, insurance, registration, and depreciation, as well as variable costs that scale with mileage, like fuel, tires, and routine maintenance. The medical and moving rate draws only from the variable side of that same study, which is part of why it’s traditionally lower than the business rate. Charitable mileage sits outside this process entirely; Congress sets that figure directly under Internal Revenue Code §170(i), which is why it hasn’t changed in years even as fuel and maintenance costs have.

Who Can Actually Claim Each Rate

Eligibility isn’t the same across all four categories, and it can be surprising.

Business mileage is mainly available to business owners, freelancers, and independent contractors. Employees generally lost the ability to deduct unreimbursed business mileage on their personal returns back in 2018 under current law, which is precisely why a solid employer reimbursement policy matters more than it used to. This policy is something our accountants can assist clients with establishing so that employee reimbursements are accurately set up for payroll service .

Medical mileage covers trips to appointments, the doctor, the dentist, physical therapy, and similar visits and is claimed as part of itemized medical deductions. Moving mileage is much narrower today; it’s essentially limited to active-duty military personnel relocating under orders, along with certain members of the intelligence community. Charitable mileage applies when you’re driving on behalf of a qualified charitable organization, and it’s reported alongside other charitable giving on your return, similar to an in-kind donation.

Should you use the standard mileage rate or deduct your actual vehicle expenses?

The answer depends on your individual tax situation. If you’re already one of our clients, contact your tax advisor and we’ll help you determine which method provides the greatest tax benefit. If you’re not yet working with us, we’d be happy to discuss your situation and explain how we can help.

To add a bit more context here, the standard mileage rate is simpler to track since it only requires a mileage log, while the actual expense method can sometimes produce a larger deduction, particularly for newer or more expensive vehicles, but it requires receipts and a careful split between business and personal use. Either way, keeping a contemporaneous mileage log (date, purpose, starting point, destination, and total miles) is expected by the IRS regardless of which method you choose, and it’s something we help clients build into their regular accounting processes.

What to Update Before Your Next Filing

A few practical items are worth reviewing now that the rate has changed mid-year:

• Update your written mileage reimbursement policy so it reflects 76¢ per mile for anything driven on or after July 1 and 72.5¢ for trips before that date.
• Make sure your accounting or expense software applies the rate based on the trip date, not the date the reimbursement is processed.
• Let anyone who submits mileage reimbursements know the rate has changed, so expense reports don’t go out with outdated figures.
• Revisit your broader second-half tax planning and preparation if your business logs high mileage, since a mid-year change like this can shift projected deductions more than people expect.
