How DoorDash, Uber and Instacart Drivers Track Mileage for Taxes

Gig driving is one of the few jobs where the biggest tax deduction is also the easiest one to lose. You are self-employed, so every business mile reduces both income tax and self-employment tax. At the 2026 business rate, 15,000 deductible miles is roughly $11,100 off your taxable income. Most drivers capture a fraction of it.

Why the platform's number is low

DoorDash, Uber, Lyft, Instacart and Grubhub all surface some form of mileage figure in the annual tax summary. It is real, and it is incomplete. Platforms generally count miles while an order is active — from accepting to completing — because that is the only span they are certain about. The rest of your shift is invisible to them:

• Driving from home to the zone where you start accepting orders;
• Repositioning between deliveries while online and waiting for an offer;
• Driving back from your last drop-off at the end of a shift;
• Time on two apps at once, where each one sees only its own trips;
• Errands the job requires — hot bags, a car wash for rideshare, a phone mount.

Drivers who compare a full log against the platform summary routinely find the platform figure covers somewhere around half to two-thirds of their real business driving. The gap is not a rounding error; it is thousands of dollars of deduction.

Which of those miles actually count

Being self-employed changes the commuting question. If your business has no fixed workplace — and a delivery driver's does not — the miles you drive once you are working for the business are business miles. Practically:

• Deductible: driving to your delivery zone to begin working, all driving while the app is on and you are available, the drive between the last drop-off and home, and trips for supplies or vehicle maintenance related to the work.
• Not deductible: anything you drove with the apps off. Groceries on the way home, the school run, a weekend trip. The mid-shift detour to your own errand is personal even if you switch the app back on afterwards.

The honest line is whether the drive exists because of the work. That test is also what you will be asked to explain, so record the purpose as you go rather than invent it later — see how to prove mileage to the IRS.

Multi-apping makes manual tracking hopeless

Running two or three platforms at once is normal, and it makes per-platform summaries unusable: nobody can reconstruct which app "owned" a given mile, and adding the summaries together double-counts overlapping stretches. What you need is a single log of the car's actual driving, marked business or personal — one source of truth, independent of which app paid for the trip.

What else drivers forget

Mileage is the big one, but it is not the only deduction. Under the standard rate you can still deduct tolls and parking paid on the job, the business share of your phone bill and data plan, hot bags and coolers, phone mounts and chargers, and platform commissions or fees shown on your statements. Keep those receipts even though the standard rate means you do not need gas receipts.

Also track revenue by platform. The 1099s you receive may not match what you actually earned after fees, and a line-by-line revenue record turns a confusing Schedule C into arithmetic.

A workable routine

1. Turn on automatic tracking so drives are recorded without you touching the phone.
2. Set a work-hours rule for your usual shifts, and save home as a named place.
3. Once a week, review the stack and swipe the exceptions to personal.
4. Photograph toll, parking and supply receipts as they happen.
5. At year end, export the dated log and hand it to whoever prepares your return.

That is fifteen minutes a month against a deduction that is usually the largest line on a gig driver's return. The platforms will keep reporting their share; the rest is yours to record.
