The Small Business Guide to Mastering the 2026 Mileage Rate

Hey there, fellow business owners! If you feel like you’re spending half your life behind the wheel running errands, meeting clients, or picking up supplies, I’ve got some news that will make those miles feel a little more rewarding.

We’ve officially rolled into 2026, and with the new year comes a new IRS standard mileage rate. Whether you’re a solopreneur with a side hustle or a growing small business with a small fleet, understanding these numbers is one of the easiest ways to keep more of your hard-earned cash in your pocket.

At RCZ Accounting, we’re all about making the "boring" stuff, like tax deductions, actually work for you. So, let’s buckle up and dive into everything you need to know about mastering the 2026 mileage rate.

The Big Number: 72.5 Cents

For 2026, the IRS has bumped the standard mileage rate for business use up to 72.5 cents per mile.

To put that in perspective, it’s a 2.5-cent increase from the 2025 rate of 70 cents. It might not sound like much at first glance, but if you’re driving 10,000 business miles a year, that’s a $7,250 deduction. That’s a significant chunk of change that stays in your business instead of going to Uncle Sam.

Why the increase? The IRS looks at national data regarding the cost of operating a vehicle. They aren't just looking at the price of gas (though we all know that fluctuates!). They’re also factoring in:

• Depreciation (how much value your car loses as you drive it)

• Maintenance and repairs (oil changes, tires, and those unexpected "check engine" lights)

• Insurance premiums

• Registration and license fees

When inflation hits these areas, the IRS eventually adjusts the rate to keep things fair for business owners.

Not All Miles Are Created Equal: Other 2026 Rates

While we usually focus on the 72.5-cent business rate, there are other rates you should be aware of, especially if you use your vehicle for more than just sales calls and coffee runs.

Interestingly, while the business rate went up, some of the other categories saw a slight dip for 2026:

1. Medical Purposes: 20.5 cents per mile (down from 21 cents in 2025). This is for miles driven to reach medical care.

2. Moving Expenses: 20.5 cents per mile. Note: This is currently limited to active-duty military members and certain intelligence community members.

3. Charitable Organizations: 14 cents per mile. This rate is set by statute and hasn’t changed in quite a while.

For most of our clients at RCZ Accounting, the 72.5-cent business rate is the "North Star" of their vehicle deductions.

Who Can Use the Standard Mileage Rate?

You might be wondering, "Am I actually allowed to use this?" In most cases, if you’re a small business owner, the answer is yes. But there are a few ground rules.

You can use the 72.5-cent rate if you are:

• A small business owner or a partner in a firm.

• A self-employed contractor or freelancer (Gig workers, this includes you!).

• A startup founder tracking early operating costs.

• An employee using your personal vehicle for business (if you aren't already being fully reimbursed by your employer).

You CANNOT use the standard mileage rate if you:

• Operate a fleet of five or more vehicles simultaneously (this is where things get more complex, and you might need to look at actual expenses).

• Have claimed a Section 179 deduction on the vehicle in the past.

• Have used accelerated depreciation (like MACRS) on the vehicle.

• Are a rural mail carrier who receives a qualified reimbursement.

Standard Mileage vs. Actual Expense Method: Which Wins?

This is the age-old question in small business accounting. Do you take the easy route (Standard Mileage) or the detailed route (Actual Expenses)?

The Standard Mileage Method

The Calculation: Total Business Miles x 0.725. The Pro: It’s incredibly simple. You don't need to save every single receipt for car washes, tires, or fuel. You just need a solid mileage log. The Con: If you drive an older, gas-guzzling truck that requires constant repairs, 72.5 cents might actually be less than what you’re spending to keep it on the road.

The Actual Expense Method

The Calculation: Total cost of gas, oil, repairs, tires, insurance, registration, and depreciation, multiplied by the percentage of the vehicle's business use. The Pro: If your actual costs are very high, this can result in a much larger deduction. The Con: The record-keeping is a nightmare. You need to track every penny spent on the car and keep every receipt.

Pro Tip from Tara: For vehicles you own, you generally have to choose the standard mileage rate in the first year the car is available for business use. If you do that, you can switch between methods in later years. However, if you lease your vehicle, you have to stick with the standard mileage rate for the entire lease period.

The IRS "Must-Haves" for Your Mileage Log

If there’s one thing that makes an IRS auditor’s eyes light up, it’s a messy or non-existent mileage log. You can't just "guesstimate" at the end of the year. To keep your 2026 deduction safe, the IRS requires you to document four specific things for every trip:

1. The Date: When did the trip happen?

2. The Business Purpose: Why did you go? (e.g., "Meeting with Client X" or "Supply run to Office Depot").

3. The Starting/Ending Point: Where did you go?

4. The Mileage: How many miles did you drive?

Going Digital: Tools to Make 2026 Easier

In 2026, there is absolutely no reason to be using a paper notebook tucked into your sun visor. Manual tracking is error-prone, and let's be honest, we all forget to write things down.

There are dozens of automated mileage tracking apps (like MileIQ, QuickBooks Self-Employed, or Hurdlr) that use your phone’s GPS to track trips automatically. You just swipe left for personal and right for business.

Even with these apps, we recommend a "Sunday Reset" routine. Every Sunday, take five minutes to review your trips for the week, add notes about the business purpose, and make sure everything is classified correctly. It’s a lot easier to remember what you did last Tuesday than what you did six months ago.

Real-World Example: Calculating Your 2026 Savings

Let's look at how this plays out for a typical local business owner.

Meet Sarah. Sarah owns a boutique catering business. In 2026, she drives her van to meet clients, deliver food, and visit local farmers' markets.

• Total Miles Driven: 12,000 miles

• Business Miles: 8,500 miles

• Personal Miles: 3,500 miles

Using the 2026 standard mileage rate: 8,500 miles x $0.725 = $6,162.50 deduction.

That’s over $6,000 that Sarah can subtract from her taxable income. Depending on her tax bracket, that could mean saving $1,500 to $2,000 in actual tax payments.

Common Mistakes to Avoid

Even with the best intentions, small business owners often trip up on mileage. Here are the most common pitfalls we see:

• Commuting Miles: Driving from your home to your primary office or place of business is generally considered "commuting" and is not deductible. However, if you have a home office that qualifies as your primary place of business, your trips from home to clients are deductible.

• Double Dipping: You can't use the standard mileage rate AND deduct the cost of gas and repairs. It's one or the other.

• Personal Errands: Stopping at the grocery store on the way back from a client meeting? You need to subtract those personal miles from the total trip.

• Lack of Documentation: "I drive about 100 miles a week" won't hold up in an audit. You need the specific log mentioned above.

Why Timely Tracking Matters Now

We are already into February 2026. If you haven't started a consistent tracking system yet, now is the time to catch up. The longer you wait, the harder it is to recreate those logs, and the more likely you are to miss out on valuable deductions.
