Business Mileage: Should You Use the Standard Rate or Actual Expenses?

Bysmall-business-tax-solutions

If you're a small business owner who drives for work: whether you're delivering food, meeting clients, or hauling equipment: your vehicle expenses can add up to one of your biggest tax deductions. But here's the thing: the IRS gives you two different ways to calculate that deduction, and picking the wrong one could cost you hundreds (or even thousands) of dollars.

Let's break down both methods so you can make the smartest choice for your situation.

What Are the Two Methods?

When it comes to deducting vehicle costs on your taxes, you've got two options: the standard mileage rate and the actual expenses method. Both are legit, both can save you money, but they work very differently.

The Standard Mileage Rate

This one's the simpler route. You just multiply your total business miles by the IRS rate for the year. For 2026, that rate is 72.5 cents per mile.

So if you drove 10,000 miles for business last year, your deduction would be:

10,000 miles × $0.725 = $7,250

That's it. No receipts for gas, no tracking your oil changes. Just keep a mileage log and you're good.

The Actual Expenses Method

This method takes more work but can sometimes give you a bigger deduction. You add up everything you spent on your vehicle: gas, insurance, repairs, registration, maintenance, even depreciation: and then multiply that total by the percentage you used your car for business.

For example, if you spent $11,300 on your vehicle last year and used it 75% for business, your deduction would be:

$11,300 × 75% = $8,475

Who Can Use These Deductions?

If you're self-employed, you probably qualify. This includes:

  • Sole proprietors and single-member LLCs
  • Gig workers (DoorDash drivers, Uber drivers, Instacart shoppers)
  • Realtors driving clients around town
  • Photographers and videographers traveling to shoots
  • Musicians hauling gear to gigs
  • Travel agents meeting with clients
  • Gym owners and personal trainers traveling between locations

Basically, if you use your personal vehicle for business purposes and you're not reimbursed by an employer, you can claim one of these deductions.

Let's Do the Math: A Delivery Driver Example

Meet Marcus. He's a delivery driver who uses his own car to make deliveries for a food delivery app. Last year, he drove 18,000 miles for work.

Option 1: Standard Mileage Rate

18,000 miles × $0.725 = $13,050

Simple. Marcus tracks his miles, and he's done.

Option 2: Actual Expenses

Marcus kept all his receipts last year:

  • Gas: $4,800
  • Insurance: $1,800
  • Repairs and maintenance: $2,200
  • Registration: $150
  • Depreciation: $3,500

Total vehicle expenses: $12,450

Marcus used his car 80% for business (he tracked this with his mileage log).

$12,450 × 80% = $9,960

In Marcus's case, the standard mileage rate wins by over $3,000. That's a big difference!

But here's the twist: if Marcus had an older car with major repair bills: say, a $4,000 transmission repair: the actual expenses method might have come out ahead.

The takeaway? Run the numbers both ways before you decide.

Common Mistakes That Can Cost You

This is where people mess up all the time. Don't let these slip-ups shrink your deduction (or worse, trigger an audit).

Mistake #1: Not Keeping a Mileage Log

This is the big one. The IRS requires written records of your business mileage. That means you need to track:

  • The date of each trip
  • Where you went
  • The business purpose
  • The miles driven

No log? No deduction. It doesn't matter which method you use: you need that mileage log either way.

There are plenty of apps that make this easy (MileIQ, Stride, Everlance), or you can go old-school with a notebook in your car. Just be consistent.

Mistake #2: Double-Dipping

You can't claim the same expense twice. If you're using the standard mileage rate, you cannot also deduct gas, repairs, or depreciation separately. That's already baked into the per-mile rate.

The only things you can add on top of the standard mileage rate are:

  • Parking fees for business
  • Tolls for business travel

That's it. Everything else is covered by that 72.5 cents per mile.

Mistake #3: Forgetting the First-Year Rule

Here's a rule that trips up a lot of people: if you want the option to use the standard mileage rate, you MUST use it in the first year you use that car for business.

Miss that window, and you're locked into the actual expenses method for that vehicle forever. You can't go back.

If you start with the standard rate in year one, you can switch to actual expenses later (and even switch back and forth). But skip it in year one, and that door closes permanently.

Why This Deduction Matters So Much

Vehicle expenses are often one of the largest deductions available to small business owners and gig workers. We're talking thousands of dollars that directly reduce your taxable income.

For a DoorDash driver putting 20,000 miles on their car, that's potentially a $14,500 deduction using the standard rate. For someone in the 22% tax bracket, that's roughly $3,190 back in their pocket.

But here's the kicker: most people either don't track their miles or pick the wrong method without doing the math. That's money left on the table.

Taking 10 minutes to compare both methods before you file could be the most profitable 10 minutes of your tax season.

Which Method Should You Choose?

There's no one-size-fits-all answer, but here are some general guidelines:

The standard mileage rate tends to work better if:

  • You drive a LOT of business miles
  • You have a fuel-efficient vehicle
  • Your car is relatively new with low repair costs
  • You hate keeping receipts

The actual expenses method tends to work better if:

  • You have an expensive vehicle
  • Your car had major repairs this year
  • You have a gas-guzzler
  • Your business-use percentage is very high

When in doubt, calculate both and compare. That's the only way to know for sure.
