Tax Strategy for DoorDash drivers
Delivery economics make the mileage deduction decisive. A courier running 1,000 miles a week at the 67-cent standard rate deducts roughly $34,960 a year, which can turn an apparently taxable profit into a much smaller number. Track on-shift miles separately from personal miles in the same week, because only on-shift miles are deductible, and keep the app's trip history export as your contemporaneous log.
Courier income swings hard with weather, season, and app promotions. Base your quarterly vouchers on your year-to-date total rather than a single good month, and hold back a fixed percentage of every payout rather than paying quarterly from a lump sum.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.
