Halfway through 2026, the IRS quietly did something it doesn't do often: it raised the standard mileage rate in the middle of the year. If your trucks, trailers, and mower rigs rack up hundreds of miles a week between warehouses, job sites, and yards, that mid-year change is worth more to your bottom line than most tax-season headlines.
What actually changed
The IRS set the 2026 business standard mileage rate at 72.5 cents per mile starting January 1, up 2.5 cents from 2025. That's the number most fleet owners planned around going into the year. Then, effective July 1, the agency bumped it again, to 76 cents per mile for the second half of 2026, citing updated cost data on what it actually costs to own and run a vehicle.
A 3.5-cent jump sounds small until you multiply it across a fleet. A tent crew running two box trucks and three pickups 25,000 miles a year combined would see roughly $875 more in deductible or reimbursable mileage for the back half of the year alone, just from the rate change. Run more routes than that during your peak season, and the number climbs fast.
Why this hits rental and lawn care operators harder than most
A software company with a few delivery vans barely notices a mileage rate change. A tent and event rental business, or a lawn care operation running a fleet of mowers, trailers, and service trucks, is a different animal. You're not just tracking one company car. You've got a delivery truck making three drops a day during wedding season, a foreman's truck bouncing between job sites, and maybe a fleet of mowing crews each logging their own routes.
Every one of those vehicles either gets reimbursed at the IRS rate if an employee drives their own truck for the job, or gets its miles deducted if it's a company-owned vehicle used for business. Miss the rate change, keep reimbursing at the old number, and you're either shorting your crew or leaving deductions on the table. Neither is a great look heading into next tax season.
Two ways this number actually gets used
There are two separate situations where the mileage rate matters, and it's easy to mix them up.
- Reimbursing employees. If a crew member drives their own vehicle for deliveries, site visits, or supply runs, reimbursing at or below the IRS rate keeps that payment non-taxable to them and deductible for you.
- Deducting business vehicle use. If the business owns the truck or trailer rig, you can generally choose between the standard mileage rate and tracking actual expenses (fuel, insurance, depreciation, repairs) for that vehicle, then use whichever method the vehicle qualifies for and works out better.
Either way, the number you multiply against your logged miles just changed twice in one calendar year. That's the kind of detail that's easy to miss when you're the one also quoting a Saturday wedding and fielding a call about a broken mower deck.
What the IRS actually wants to see in a mileage log
Here's where most small operators get sloppy, and where an audit turns painful. IRS Publication 463 doesn't ask for much, but it's specific about what it asks for:
- Date, destination, and business purpose for each trip. "Delivered tent package, Johnson wedding" beats nothing every time.
- Miles driven per trip, or a reliable way to calculate them.
- Odometer readings only at the start and end of the tax year, or when a vehicle enters or leaves business use. You don't need to log the odometer on every single drop-off.
- Timely records. The IRS calls this the "at or near the time" requirement. A log rebuilt from memory in March, trying to reconstruct what happened the previous June, gets far less credibility than one built weekly as the season happened.
If a truck does double duty, running personal errands on the weekend and job deliveries during the week, you also need to split personal miles from business miles. Lump them together and the whole log becomes suspect.
The IRS's general rule on how long to keep any of this: three years from the date you filed the return the mileage supported, longer if you underreported income or filed a claim for a loss. For a seasonal business, that means the mileage log from this year's wedding season should probably still be sitting in a drawer, or a folder, well into 2029.
Turning a tax rule into a habit your crew will actually keep
Knowing the rule and getting five drivers to log every trip contemporaneously are two very different problems. The paper log in the glovebox works right up until it gets left in a truck console for a season, which is exactly how too many rental operators end up guessing at mileage numbers in April.
This is one of the quieter reasons operators lean on Apex Rental Pro's built-in mileage tracking instead of a spreadsheet nobody opens. Every job, delivery, and pickup already lives on the calendar, so logging a trip against a real event takes seconds instead of becoming a Sunday-night chore. Pair that with the expense tracking most operators are already running, and the mileage rate change stops being a line item you catch too late.
If you're running more than one truck now, the bigger discipline problem usually isn't the mileage rate itself, it's the handoff between the office booking the job and the crew actually driving to it. That's the same gap we cover in the office-to-crew handoff guide, and it's worth fixing at the same time you tighten up mileage logging, since both come down to capturing the right details the moment work happens, not reconstructing them later.
Seasonal payroll is the other place this connects. If you're already sorting out overtime rules for seasonal crews, add mileage reimbursement to that same review. A driver who's owed 76 cents a mile instead of 72.5 cents is a small correction now; it's a bigger one if you don't catch it until a W-2 season later. And if your fleet has grown enough that a maintenance schedule is already on your radar, mileage data is a useful side effect of that tracking too, since the same odometer readings that trigger a service interval can back up your tax records.
None of this needs to be complicated. Businesses scaling past one crew or moving off spreadsheets and group texts tend to hit this exact wall: the rules didn't get harder, there are just more trucks, more drivers, and more room for a rate change to slip past everyone until the accountant asks about it. Build the habit once, tie it to the jobs you're already scheduling, and a mid-year IRS adjustment becomes a five-minute update instead of a scramble.
