Rideshare and delivery driving has a tax quirk that catches new drivers off guard every year: the platform doesn't withhold anything. No federal tax, no state tax, no Social Security or Medicare. Every dollar that hits your bank account is gross, not net — and the gap between what you earned and what you actually keep is bigger than most new drivers expect.
As an independent contractor, you're both employee and employer for Social Security and Medicare purposes, which means you pay both halves — 15.3% self-employment tax on your net earnings, on top of ordinary income tax. This is the single biggest reason gig income "disappears" faster than a driver expects when tax season arrives, especially for anyone who hasn't set money aside as they earned it.
For rideshare and delivery drivers, vehicle mileage is typically the largest deduction available, and it's also the one most commonly under-tracked. The IRS standard mileage rate (updated annually, generally in the high-60s to low-70s cents per mile range in recent years — check the current year's rate) is multiplied by your business miles to produce a deduction that directly reduces taxable income.
The critical detail: all miles driven while available for a ride or delivery count, not just miles with a passenger or order in the car. Miles driving to a pickup, cruising while waiting for the next ping, and driving between drop-off and the next pickup all qualify — and drivers who only log miles with a fare active are leaving a substantial deduction unclaimed.
| Mileage tracking method | Accuracy | Effort |
|---|---|---|
| End-of-year estimate from memory | Poor — significantly underclaims and is hard to defend in an audit | Low |
| App-based automatic tracking | Good, if reviewed for accuracy | Low ongoing |
| Manual log per trip (odometer start/end) | Excellent, fully defensible | Higher, but the most audit-proof |
You generally cannot claim standard mileage and actual vehicle expenses (fuel, maintenance, depreciation) for the same vehicle in the same year — pick whichever method gives a larger, defensible deduction and use it consistently.
Because nothing is withheld, the IRS expects estimated tax payments four times a year (mid-April, mid-June, mid-September, and mid-January of the following year) rather than one payment at filing time. Underpaying through the year can trigger a penalty even if the full amount is paid by the April filing deadline — so setting aside a percentage of each week's earnings as you go, rather than scrambling at each quarterly deadline, is the difference between a manageable tax bill and a stressful one.
Drivers running Uber and Lyft simultaneously, or DoorDash alongside Instacart, receive separate tax forms from each platform (1099-NEC or 1099-K depending on the platform and your earnings level) — and all of it needs to be combined onto a single Schedule C for your overall gig business, with mileage and expenses tracked in aggregate, not per platform. Reconciling multiple platforms' summaries against your own mileage log is the only reliable way to catch discrepancies before they become a filing error.
