The deduction is not a refund
A mileage deduction reduces business profit used in tax calculations. It is not a dollar-for-dollar credit and it does not reimburse your fuel purchase.
The actual tax effect depends on your marginal income-tax rate and self-employment tax position.
Records decide which miles are defensible
Keep a timely log showing the date, distance, and business purpose. Platform estimates can help reconcile activity, but your own records should support the miles claimed.
Commuting and personal driving are generally different from business travel; fact patterns matter.
Choose a vehicle method carefully
The standard mileage rate generally includes depreciation and ordinary vehicle operating costs. Do not add gas, repairs, insurance, or depreciation again for the same mileage period.
Eligibility to switch methods can depend on when and how a vehicle was placed in service. Review current IRS guidance.
Frequently asked questions
Can DoorDash drivers deduct mileage?
Business mileage can generally be deductible when it is ordinary, necessary, and properly substantiated. Whether a specific trip qualifies depends on its business purpose and your facts.
Can I use the miles shown in the DoorDash app?
Use platform data as one reconciliation source, not your only record. A contemporaneous mileage log with date, business purpose, and distance is stronger evidence.
Can I deduct gas in addition to mileage?
Generally not when using the standard mileage method for the same vehicle period. Gas and most operating costs are built into the standard rate.
Does the mileage rate ever change during a year?
It can, but a midyear change is unusual. This calculator stores rates with effective dates and applies only changes confirmed in official IRS guidance.
What if I drive for two apps at once?
Count an eligible mile once. Keep a consolidated log and allocate business purpose when needed rather than duplicating the same distance across platforms.
