IRS Standard Mileage Rate 2026: Why It Jumped to 76 Cents Mid-Year (Plus a 2027 Outlook)

If you drive for work, the IRS standard mileage rate you can deduct just changed twice in one year. It started 2026 at 72.5 cents per mile for business use, then jumped to 76 cents per mile effective July 1 — a mid-year increase the IRS almost never makes.

Here’s the full breakdown of both halves of the year, why the change happened, and what it means whether you’re a rideshare driver, a small business owner, or just tracking medical or charitable miles.

2026 Mileage Rates: First Half vs. Second Half

Because of the July 1 change, 2026 effectively has two different rate schedules depending on when you drove. The original 2026 rates were set by IRS Notice 2026-10 back in December 2025, then revised for the second half of the year:

The charitable mileage rate is set by statute (Internal Revenue Code Section 170(i)), not by the IRS itself, which is why it hasn’t moved in years regardless of gas prices. The business and medical/moving rates, by contrast, are based on an annual — and now mid-year — study of the actual fixed and variable costs of operating a vehicle.

One important detail: this isn’t retroactive. If you drove for business in March, you use 72.5 cents for those miles even though you’re filing after July 1. Keep your mileage log split by date so you’re applying the right rate to the right trip.

Why the IRS Made a Rare Mid-Year Change

The IRS doesn’t like to move mileage rates outside its normal December announcement — doing so mid-year creates real complexity for anyone tracking deductible miles. It’s happened only four times before 2026: in 2005, 2008, 2011, and 2022, each time tied to a sharp spike in fuel costs.

This time was no different. According to AAA data cited in the IRS’s own announcement, the national average price for a gallon of regular gasoline went from $2.819 on January 8 to $3.890 by mid-July — a 38% increase in about six months. The IRS revised its cost study mid-cycle rather than asking drivers to absorb rising fuel costs on the old rate through year-end. You can see the IRS’s own guidance on business vehicle use at Tax Topic 510 on IRS.gov.

The new rates apply the same way to gas, diesel, hybrid, and fully electric vehicles — the IRS doesn’t distinguish by fuel type for these purposes.

Who Can Actually Claim the Business Mileage Deduction

This is the part that trips people up. The business standard mileage rate is mainly useful to the self-employed — rideshare and delivery drivers, freelancers, and small business owners filing a Schedule C or claiming vehicle use for an LLC or S-corp.

Most W-2 employees can’t deduct unreimbursed mileage on their personal return at all. Since the 2017 tax law changes, miscellaneous itemized deductions for unreimbursed employee expenses are suspended, with narrow exceptions for certain reservists, state and local government officials, performing artists, and eligible educators. If your employer reimburses mileage, that’s handled through their own reimbursement policy, not your tax return.

Example — Maria, a rideshare driver. Maria drives 25,000 business miles in 2026, split evenly between the two rate periods: 12,500 miles at 72.5 cents ($9,062.50) and 12,500 miles at 76 cents ($9,500). Her total mileage deduction for the year comes to $18,562.50 — about $437.50 more than if the rate had stayed flat at 72.5 cents all year.

Example — Jake, a delivery driver. Jake logs 15,000 miles for DoorDash and Instacart deliveries, also split evenly: 7,500 miles at 72.5 cents ($5,437.50) plus 7,500 miles at 76 cents ($5,700), for a total deduction of $11,137.50. Because he’s self-employed, this comes straight off his Schedule C income before self-employment tax is calculated.

If you’re weighing whether the standard mileage rate or tracking actual vehicle costs (gas, insurance, depreciation, repairs) gets you a bigger deduction, my guide to claiming the sales tax and other costs on a car purchase walks through when the actual-expense method can beat the standard rate, especially for a newer or more expensive vehicle.

Medical, Moving, and Charitable Mileage

The medical mileage rate (23.5 cents per mile as of July 1) covers trips to appointments, treatments, and pharmacy runs, but it only helps if your total medical expenses clear the 7.5% adjusted gross income floor — see my full breakdown of the medical expense deduction for how that threshold works in practice.

Moving mileage is far more limited than it used to be. It’s only deductible for active-duty members of the Armed Forces moving under permanent-change-of-station orders, and — new this year under the One Big Beautiful Bill (OBBB) — certain members of the intelligence community. If you’re a civilian relocating for a new job, this deduction doesn’t apply to you; my tax tips for job seekers post covers what job-search and relocation costs are still deductible.

Charitable mileage stays at 14 cents per mile no matter what happens to gas prices, since Congress — not the IRS — controls that rate. If you volunteer regularly and rack up miles doing it, my guide to the charitable tax deduction covers how to document and claim it alongside other charitable giving.

Common Issues to Watch Out For

Using one rate for the whole year. I’ve seen people just apply 76 cents to every business mile driven in 2026. That overstates your deduction for the first six months — split your log at June 30/July 1 and apply the correct rate to each half.

Assuming a W-2 job qualifies. If you’re not self-employed and your employer doesn’t reimburse mileage, the standard deduction almost certainly makes more sense than trying to itemize unreimbursed vehicle expenses that are largely no longer deductible.

Poor mileage records. The IRS expects a contemporaneous log — date, purpose, starting/ending odometer or total miles — not a rough estimate reconstructed at tax time. Apps that auto-track trips make this far easier than a paper notebook.

Confusing commuting with business miles. Driving from home to your regular workplace is commuting and isn’t deductible, even for the self-employed. Miles between job sites, client visits, or supply runs are the ones that count.

Switching methods on a leased vehicle. If you use the standard mileage rate on a leased car, you have to stick with it for the entire lease term — you can’t switch to actual expenses partway through.

Looking Ahead: 2027 Outlook

The IRS typically announces the following year’s standard mileage rates in December, based on its annual cost study. Given how sharply gas prices moved in 2026, it’s worth watching whether the 2027 starting rate reflects the higher fuel costs baked in during the second half of this year, or whether prices ease back down by then.

I wouldn’t rule out another mid-year adjustment either — the 2026 change is a reminder that the IRS will act outside its normal calendar when fuel costs move enough to matter.
