Are DoorDash Mileage Estimates Accurate? What Every Platform's Mileage Report Leaves Out

Are platform mileage estimates accurate?

They are accurate about what they measure and silent about the rest. DoorDash reports on-delivery miles. Lyft reports online trip miles. Instacart and Amazon Flex report nothing. Uber is the broad exception and reports online miles. Every one of those numbers was built to explain pay, not to substantiate a deduction, so treat it as a floor.

That distinction costs real money. The 2026 business standard mileage rate runs 72.5 cents per mile for January through June (Notice 2026-10) and 76 cents per mile from July 1 (Announcement 2026-11). Every mile that falls outside the app's definition is worth about three quarters of a dollar to you and nothing to the platform.

What each app actually reports

The wording on each platform's own paperwork is the tell. DoorDash calls its figure an estimate and scopes it to on-delivery driving. Lyft's annual summary covers online trip mileage. Uber describes three tracked categories. Instacart and Amazon Flex hand you a 1099 and stop there. Here is the same information side by side.

Lyft's exclusion is the most explicit of the group. TurboTax's rideshare guidance states the Annual Summary "won't include the mileage when driving to your first passenger, between passengers and on the way home at the end of the day," and tells drivers to keep personal records of those miles separately. If you drive for either app, the DoorDash mileage tracker and Lyft mileage tracker pages break the same gap down platform by platform.

How big is the gap, in real numbers?

The best public measurement of engaged-versus-total driving comes from Judd Cramer and Alan Krueger's study of Uber data. Measuring capacity utilization by the share of miles driven with a fare-paying passenger in the car, they found that across five cities, UberX drivers averaged 61.0 percent. In Los Angeles the figure was 64.2 percent, and for every mile driven with a passenger, UberX drivers drove 0.56 mile without one.

Two honest caveats. That data is rideshare, not delivery, and it is a decade old. Courier work has its own shape - restaurant waits, stacked orders, long returns from suburban drop-offs - so your ratio is your own. What the study establishes is that the empty share is structural and large, not a rounding error you can ignore.

What the missing miles are worth in 2026

Run the gap through the 2026 rates. With the split year, a driver whose miles land evenly across both halves is deducting an effective 74.25 cents per mile. The table below prices a weekly gap between what your app reports and what you actually drove.

Why the platforms count it this way

Engaged mileage is a pay concept, not a tax concept. Platforms measure the distance attached to an order because that is what they price, what they use for contractor pay guarantees, and what a support agent can look up when a driver disputes a payout. Nobody at DoorDash decided your deadhead miles are nondeductible. They just never had a reason to store them.

Accuracy inside the measured window is also imperfect. The distance an app records is typically a computed route, not your odometer, so detours, closed roads, apartment-complex loops, and second trips back to the door go missing. The driver tax firm ATBS warns that mileage tracked by delivery apps "can be off by 10% or more." DoorDash's own word for the figure is estimate.

The miles no app will ever have

Some categories are invisible to every platform by design:

• The drive from a drop-off back toward a busier zone, before the next order lands.
• Circling or repositioning while the app is on and nothing is attached.
• Returning an undeliverable order to the merchant after the order closes.
• Business errands off the clock - a supply run for insulated bags, a trip to the bank for a paper check.

There is a boundary worth knowing: the first drive out from home and the last drive home are usually treated as nondeductible commuting, so more miles than you think are contested rather than simply missing. The rules on that split are covered in our breakdown of which gig miles count as commuting.

Multi-apping makes the numbers worse, not better

If you run two apps at once, the platform figures stop being additive. A single mile driven with DoorDash and Uber Eats both open can appear inside both estimates, so stacking the totals overstates your driving - while each number, on its own, still understates it. Add a third app and the arithmetic is meaningless. Drivers who split shifts across the Uber Eats mileage tracker, Instacart mileage tracker, and Amazon Flex mileage tracker pages face exactly this problem, and one shift-level log is the only clean answer.

Why an estimate is weak documentation

Even if a platform reported every mile, the format would be wrong. Treasury Regulation 1.274-5T requires an account book, diary, log, trip sheet, or similar record showing the mileage, the date, the destination, and the business purpose of each business use, prepared "at or near the time of the expenditure or use." A single annual total carries none of those elements per trip.

It is also not your record. The regulation contemplates the taxpayer's own contemporaneous documentation, with third-party material serving as corroboration. A January email listing one number for the prior year is corroborating evidence, not the log. What examiners look for is spelled out in our walkthrough of what an IRS mileage audit asks for.

One piece of good news in the same regulation: you do not need a daily ritual. A log maintained on a weekly basis, accounting for use during that week, counts as a record made at or near the time of use.

The reconstruction trap

Car expenses sit under section 274(d) strict substantiation, which means the usual fallback does not apply. Under the Cohan rule, courts can sometimes estimate a deduction a taxpayer clearly incurred. For vehicles, that door is closed - passenger automobiles are listed property, and section 274(d) overrides Cohan.

Khan v. Commissioner (T.C. Summary Op. 2025-5) is a plain illustration. The taxpayers offered generalized explanations and spreadsheets built after the fact. The court disallowed the vehicle and travel deductions, finding they "did not maintain adequate books or records" under section 274(d), and refused to estimate: "we cannot apply the Cohan rule to estimate the business use of the automobile." Summary opinions cannot be cited as precedent, but they show how the standard gets applied to ordinary taxpayers. If you are already behind, read what to do when you did not track your mileage before you invent a spreadsheet.

Build the log, then use the app number to check it

Four fields per trip: date, miles, destination, and business purpose. Captured during the week it happened. Complete across every app you ran that day, with no double counting. That is the whole standard, and it has been the standard since long before delivery apps existed.

Automatic capture is what makes it survivable at gig-work volume - GigOdo detects drives, timestamps them, and keeps a purpose field on each one, free and with no trip cap, plus a CPA-ready report pack at filing time. More on the recordkeeping rules is collected in our mileage and records guides.

Then give the app estimate its real job. At year end, put it next to your own total. Your log should be meaningfully higher - if it is not, you have trips your tracker missed, probably shifts where it never started. A log that comes in below the platform's engaged-only figure is a broken log, and that is worth catching in December rather than April.

Keep the platform emails and summaries either way. Independent third-party evidence that you were working on a given date supports the log rather than replacing it, and it costs nothing to save the PDF.

Bottom line

Your platform's mileage number answers a question you did not ask: how far did you drive with an order attached. The deduction runs on a different question - how far did you drive for the business - and only your log answers it. At 76 cents a mile for the rest of 2026, the gap between those two numbers is the most expensive paperwork problem in gig work.
