The Mileage Deduction Demystified: How to Claim It in 2026

Who Can Actually Claim the Mileage Deduction?

If you're self-employed, a freelancer, or a small business owner, you drive for your business. That's almost a given. Client meetings, supply runs, job sites, the post office — it adds up fast. And every one of those miles is potentially deductible.

But here's where a lot of people get tripped up: W-2 employees generally can't deduct mileage anymore. The Tax Cuts and Jobs Act eliminated that deduction for most employees starting in 2018, and that change is now permanent. If your employer doesn't reimburse you for driving, you're mostly out of luck on the federal return.

If you're self-employed — filing a Schedule C, running an S-corp, working as a freelancer or contractor — you're in a completely different situation. The mileage deduction is very much available to you, and it's one of the most straightforward write-offs you have.

What Trips Actually Count as Business Miles?

This is where people make a lot of assumptions that don't hold up. Not every drive that feels work-related is deductible.

Trips that count: driving to meet a client, traveling between job sites, going to pick up supplies or materials, heading to a co-working space you use for business, attending a professional conference, driving to the bank to make a business deposit.

Trips that don't count: commuting from your home to your regular office. This one surprises people. The IRS has always been clear — the drive from your house to your primary place of business is personal, not deductible, even if you're thinking about work the whole way there.

The rule of thumb: if the drive has a clear business purpose and you can explain what it was, it's probably deductible. If you'd have trouble explaining it to an auditor, think twice before counting it.

How to Track Mileage So It Holds Up to the IRS

Before we get into which deduction method to use, there's something that applies to both of them equally: you have to track your miles. There's no version of the mileage deduction — standard rate or actual expenses — where the IRS just takes your word for how much you drove.

The IRS doesn't just want a mileage total at the end of the year. They want a contemporaneous mileage log — you need to be recording trips as they happen, not reconstructing them from memory in March.

For each business trip, the IRS expects you to record: the date, the destination, the business purpose, and the miles driven. The easiest approach by far is a mileage tracking app. Apps like MileIQ, Everlance, or Driversnote run in the background on your phone and automatically log every trip using GPS. Most cost less than $10 a month — far less than the deduction you'd lose if you couldn't substantiate your miles.

The Two Methods: Standard Rate vs. Actual Expenses

When it comes to deducting vehicle costs, the IRS gives you a choice. You can use the standard mileage rate, or you can track your actual expenses. You don't get to use both — you pick one.

The standard mileage rate is exactly what it sounds like: multiply your business miles by the IRS rate, and that's your deduction. For 2026, the rate is 72.5 cents per mile. It's simple. You track your miles, multiply, done. No receipts for gas, no oil change records, no depreciation calculations.

The actual expense method is more work, but potentially more valuable. You track every dollar you spend on the vehicle — gas, insurance, registration, oil changes, tires, repairs, loan interest — and deduct the portion that's attributable to business use.

Running the Numbers: Which Method Wins?

The right answer depends on your specific situation. Here's a real-world comparison. Say you drive 18,000 business miles a year in a vehicle with $5,500 in total annual costs. Your vehicle is worth $28,000, and 70% of your total driving is for business.

In this example, the standard rate wins by a significant margin. That's actually pretty common for most small business owners — the standard rate is designed to be generous. But the actual method can pull ahead with newer expensive vehicles or scenarios where bonus depreciation creates a massive first-year write-off.

The Mistakes I See Most Often

Not tracking at all. This is the big one. People know they drive for business, they just never write it down. At tax time, they try to reconstruct it from memory or Google Maps history. That's not a mileage log — and if the IRS asks for documentation, it won't cut it.

Thinking that an estimate is enough. The IRS wants a log with dates, destinations, and purposes. An educated guess isn't documentation. If you can't show the work, you can't claim the deduction.

Forgetting to track the full year. A lot of people start logging miles in Q4 when they realize taxes are coming. The IRS can tell when a mileage log was created. Log trips all year.

Forgetting parking and tolls. These are deductible on top of your mileage deduction — they're not included in the per-mile rate. Keep those receipts separately.

Bottom Line

The mileage deduction is one of the most valuable write-offs available to self-employed people, and it's genuinely simple once you have a tracking system in place. At 72.5 cents a mile, 10,000 business miles a year is $7,250 off your taxable income. 20,000 miles is $14,500.

The barrier isn't complexity — it's consistency. The people who miss out are the ones who mean to track their miles and never quite start.

If you want help figuring out which method makes sense for your situation, or if your vehicle deductions are getting complicated, I'm happy to take a look.
