In 2026, while the Uber app automatically tracks "online miles" (the distance you drive while the app is active and looking for a ride), most professional drivers keep a separate, manual log or use a dedicated mileage-tracking app like TripLog or Hurdlr. This is because the Uber-provided tax summary often undercounts a driver's truly deductible miles—specifically the "deadhead" miles driven back to a busy area after a drop-off or the distance traveled for vehicle maintenance. For tax purposes in the US, drivers can deduct a standard mileage rate (roughly $0.67 per mile in early 2026) from their income. Relying solely on Uber's data can lead to overpaying on taxes by hundreds or even thousands of dollars. Therefore, while the platform provides a baseline, a savvy driver treats mileage tracking as a critical part of their business bookkeeping to ensure they capture every work-related mile from the moment they leave their driveway to the moment they return home.
