Mileage Deduction Guide: How to Track, Log, and Maximize Every Mile

For gig drivers, the mileage deduction is the single most powerful tax tool you have. At $0.70 per mile in 2025, driving 10,000 business miles in a year equals a $7,000 deduction against your taxable income. No other deduction — phone, home office, even health insurance — comes close.

Yet most drivers leave thousands on the table every year because they don’t track all their miles, don’t understand what counts, or get tripped up by IRS recordkeeping rules.

This guide covers everything you need to know: what miles count, what doesn’t, how to track them properly, what the IRS requires in an audit, and how to maximize every single mile you drive.

What Miles Count as Business Miles?

The IRS defines business miles as any driving done for work purposes. For gig drivers, this is broader than most people realize.

Rideshare Drivers (Uber, Lyft):

Driving to pick up a passenger ✓
Transporting the passenger to their destination ✓
Driving between one drop-off and your next pickup ✓
Driving from a low-demand area back to a busy zone (repositioning) ✓
Driving to a restaurant area while waiting for a DoorDash order ✓

What does NOT count:

Commuting from your home to your first pickup location (unless you have a home office — see our Home Office Deduction guide)
Driving from your last drop-off back home (this is personal commuting)
Personal errands done while your phone is “on” in the background

Delivery Drivers (DoorDash, Uber Eats, Grubhub, Instacart):

Driving to the restaurant to pick up the order ✓
Delivering to the customer ✓
Driving between deliveries (you can chain orders on DoorDash, for example) ✓
Returning to a high-demand area between deliveries ✓
Driving to pick up groceries for Instacart ✓

The key principle: Once you start your “shift” (go online in an app), almost all driving until you go offline is business mileage. The only exception is personal detours — grabbing coffee at a store on your way home after your shift ends counts as personal. But driving to that coffee shop during your shift to grab an order? Business.

How to Track: IRS Requirements

The IRS has one non-negotiable rule: your mileage log must be contemporaneous. This means you record miles at or near the time you drive, not at the end of the year from memory.

What the IRS accepts:

A mileage tracking app on your phone (Stride, Everlance, MileIQ, Gridwise, Hurdlr)
A paper logbook in your car
A spreadsheet updated daily
A combination (app for most miles, manual entry for exceptions)

What the IRS does NOT accept:

Reconstructing your miles from memory at tax time
Estimating based on gas receipts
Using only Uber or Lyft’s trip data (they miss 40–50% of deductible miles — the deadhead miles between rides)
Recording miles only once a week or once a month

Why apps beat paper logs. A mileage tracking app automatically records date, starting point, destination, purpose, and miles driven. It creates a timestamped, tamper-proof record. The IRS considers digital logs more reliable than handwritten ones because they’re generated in real time.

What to do if you lose your phone or the app crashes. If you have a gap in your log, the IRS allows reasonable estimation — but you should only use this as a last resort. If you drove for 3 days and lost the data, you can estimate based on:

Your average daily miles from other logged days
Receipts (parking, tolls, car washes)
Ride-hailing trip summaries from the app

But estimate conservatively. If your app logged 120 miles/day on Tuesday and Thursday, and you estimate 100 miles for Wednesday, that’s defensible. Estimating 200 miles for Wednesday would raise red flags.

How to Maximize Your Deduction

1. Run the tracker every time you’re online. Even if you only dash for 30 minutes, log it. Those short trips add up over a year. One DoorDash driver we spoke to averaged 15 miles per dash but logged over 10,000 miles annually because he ran the tracker on every single trip.

2. Log non-passenger, non-delivery miles. The biggest mistake drivers make is only logging miles when they have an active order. Repositioning drives — driving from a quiet neighborhood to a busy area — are 100% deductible. If you’re not actively delivering but you’re driving to get to more orders, that’s business mileage.

3. Review your log weekly. Most apps show you a summary at the end of the week. Spend 60 seconds checking: did you miss any trips? Did the app misclassify a personal drive as business? Catching errors early is much easier than trying to reconstruct them months later.

4. Photograph your odometer. Take a photo of your car’s odometer on January 1st and December 31st. This gives you a year-end reality check: if your app says you drove 15,000 business miles but your odometer only went up 8,000 total, something is wrong.

5. Track every mile, not just the big ones. That 2-mile drive to grab a DoorDash order? Logged. The 5-minute drive between two Instacart stops? Logged. Small miles compound into thousands over a year.

What the Standard Mileage Rate Covers

The IRS standard mileage rate of $0.70 per mile in 2025 is a bundled rate. It covers:

Gasoline (or electricity for EVs)
Oil changes
Tire wear and rotation
Repairs and maintenance
Insurance premiums
Vehicle registration fees
Depreciation (the loss of value as your car accumulates mileage)
Lease payments (for leased vehicles)

If you use the standard mileage rate, you cannot separately deduct any of these items. This is a common mistake. Drivers who take the standard mileage rate AND also deduct their gas receipts or insurance are double-dipping, which the IRS explicitly prohibits.

The standard mileage rate is designed to be simple: you multiply miles by the rate, and that single number covers everything related to operating your vehicle. For most gig drivers, this is the easier and more advantageous method.

When Actual Expenses Might Beat Standard Mileage

The standard mileage rate is simpler, but in some cases, the actual expense method saves more money. This happens when:

You drive a fuel-inefficient vehicle (truck or large SUV) and have high actual costs
You lease a new car and your lease payments are substantial
You have significant deductible vehicle expenses beyond mileage (though this is rare for most drivers)

If you expect actual expenses to exceed the standard mileage rate, you should use our Mileage Deduction Calculator to compare both methods side by side.

Important: You can only switch to the actual expense method in years after your first year of business use. If you used standard mileage in year one, you’re locked into standard mileage for the rest of the vehicle’s useful life.

State-Specific Rules

Some states have different standard mileage rates or additional rules:

California: Uses its own mileage rate (typically slightly different from the federal rate). If you drive primarily in California, you may need to calculate deductions under both federal and state rules.
New Jersey: Has a standard mileage rate that differs from the federal rate.
Other states: Most follow the federal rate, but always check your state’s Department of Revenue website.

What Happens in an Audit?

The IRS doesn’t audit gig workers at a high rate, but when they do, mileage is one of the most common triggers. Here’s how to protect yourself:

Keep your log for at least 3 years after filing. If you file in April 2026 for the 2025 tax year, keep your mileage records until at least April 2029.

Have supporting documentation. Beyond your mileage log, keep:

Receipts for major vehicle repairs (shows the vehicle was in use)
Insurance statements (shows continuous ownership/lease)
Photos of your odometer at year start and year end
Screenshots from your tracking app showing consistent daily activity

Be conservative. It’s always better to log 12,000 miles and have the IRS accept that than to log 20,000 miles and have no way to substantiate 8,000 of them. The IRS presumes you overstated when you can’t prove otherwise.

Common Mistakes to Avoid

Only logging rides with passengers. Deadhead miles between pickups are 100% deductible.
Mixing up personal and business. If you pick up your kids from school on the way home from a DoorDash delivery, the portion after the delivery is business. The portion before is personal.
Forgetting about side hustles. If you drive for both Uber and DoorDash, combine the miles from both. They’re the same business activity.
Using the wrong rate. Make sure you’re using the current year’s rate. The 2025 rate is $0.70/mile. Using last year’s rate is incorrect.
Not adjusting for business-use percentage. If you use your car 80% for business and 20% for personal, you can only deduct 80% of actual expenses (though the standard mileage rate is applied to total business miles without this adjustment).
