Rideshare, delivery and platform work pays gross. The platform withholds nothing, reports what it paid you, and the tax is yours to calculate and pay during the year.
Mileage is usually the largest deduction and the one most often left unclaimed. The IRS standard mileage rate covers fuel, wear and depreciation in a single figure per business mile, and for a driver it commonly exceeds every other expense combined.
Platform fees, commissions, phone costs apportioned to work, insulated bags, car cleaning and parking are deductible too. What remains after all of it is the profit that self-employment tax of 15.3% and income tax are charged on.
Gross platform earnings are a poor guide to what you owe — a driver with heavy mileage may owe far less than their reported income suggests. The deductions have to be recorded to count, which is why a log kept through the year is worth more than one reconstructed in April.
