How to Track Mileage for DoorDash, Uber, and Lyft Taxes

June 2026 · 6 min read

Mileage is the largest single tax deduction available to most gig drivers — and the one most commonly underclaimed. At the 2026 IRS standard mileage rate of 70 cents per mile, every 1,000 miles tracked and documented is worth $700 in deductions. Over a full year of full-time driving, that can easily mean $15,000–$25,000 in mileage deductions. But you only get the deduction if you have records the IRS will accept, kept in the way the IRS requires.

What the IRS Actually Requires

The IRS Publication 463 specifies that vehicle deductions require "adequate records" — a log that shows, for each business trip: the date, the destination or general area of travel, the business purpose, and the number of miles driven. Records must be "contemporaneous" — kept at or near the time of each trip, not reconstructed from memory weeks or months later.

This contemporaneous requirement is the one most gig workers violate without realizing it. Reconstructing mileage from memory at tax time — even using bank statements or platform summaries to jog memory — is not contemporaneous recordkeeping and won't survive an audit. A log maintained trip-by-trip, automatically or manually, satisfies the requirement. A summary created after the fact, even from legitimate sources, does not.

Why Platform Mileage Reports Are Not Enough

DoorDash, Uber, Lyft, and Instacart all provide annual mileage summaries. These are useful reference documents, but they systematically undercount your total business miles by missing several categories the IRS allows you to deduct.

Platform apps track mileage only while you're on an active delivery or ride — from acceptance to completion. They don't track: miles driven to the zone where you start working; miles between completed orders while you're still logged in and waiting; miles from your last order back home if you drive there as part of wrapping up your shift; or miles to supply stores or banks for work-related purposes. Drivers who track their own mileage consistently report 15–30% more business miles than platform reports show. At 70 cents per mile, 5,000 additional miles equals $3,500 in additional deductions.

What Qualifies as a Business Mile

Deductible miles include: miles to pick up an order or passenger (from where you are when you accept), miles completing a delivery or ride, miles between orders while actively working (logged into the app), miles to a car wash you use for your vehicle in connection with gig work, and miles to any store to purchase supplies used in your gig work.

Non-deductible miles include: miles from home to the area where you normally start working — the IRS treats this as commuting, which is never deductible regardless of occupation. Miles for personal errands mixed into a work shift. Miles from your last delivery back home, unless your home is also your principal place of business (rare for gig drivers).

Odometer Records: The Supporting Documentation

In addition to trip-by-trip logs, the IRS expects you to document your vehicle's total annual mileage. The standard approach: photograph your odometer on January 1 and December 31 each year. This lets you calculate total annual mileage and verify that your claimed business mileage is a plausible percentage of total driving. If you claim 35,000 business miles but your odometer records show only 40,000 total miles, that claim looks credible. If your total odometer increase was 25,000 miles, a 35,000-mile business claim creates obvious problems.

Tracking Methods Compared

Paper log: A notebook in the glovebox with date, destination, purpose, and miles for each trip. Completely IRS-compliant if maintained consistently. In practice, almost no full-time gig driver maintains this consistently across 100+ weekly trips.

Spreadsheet: Manual data entry into a spreadsheet, updated after each session or daily. Better than a paper log for organization and backup, but still depends on discipline and accurate recall. Doesn't meet the contemporaneous standard if entries lag by more than a day or two.

Automatic tracking app: Apps like GigMile use your phone's GPS to automatically detect and log driving trips. The log is contemporaneous by design — every trip is recorded as it happens with GPS-verified start and end points, timestamps, and mileage. After each session, you review trips and tag them by platform or mark personal trips for exclusion. At tax time, export the full IRS-ready log.

Setting Up Automatic Tracking

1. Create a free GigMile account and grant background location permission — this is required for automatic detection.
2. GigMile runs silently and detects when you begin driving, logging trip start automatically.
3. After each shift, open the app and review detected trips: tag each one by platform (DoorDash, Uber, etc.), mark personal trips to exclude, and add any trips the app might have missed.
4. Record your January 1 odometer reading and update it each December 31.
5. At tax time, export your annual mileage report — it includes every field the IRS requires and is formatted for direct use on Schedule C.
