Self-employment tax for rideshare drivers starts with a surprise that costs new drivers real money. Uber and Lyft do not withhold anything. Not income tax, not Social Security, not Medicare. The money that lands in your account each week is gross pay, and the tax bill arrives later, all at once, unless you plan for it. I have seen that surprise turn a decent side income into a stressful April, and it is almost always avoidable.
The key point: you are an independent contractor, not an employee. Your driving income goes on Schedule C, your profit goes on Schedule SE, and self-employment tax is 15.3 percent of 92.35 percent of that profit. That works out to about 14.13 percent of your net profit. A driver who nets $20,000 for the year owes about $2,826 in self-employment tax, before income tax. A driver who nets $40,000 owes about $5,652. Those numbers assume the Social Security wage base has not been hit elsewhere, which matters if you also hold a W-2 job, since wages already taxed for Social Security reduce what is left to tax at the 12.4 percent Social Security portion.
But here is where most new drivers overpay. The 1099 figure is not your profit. Platforms report gross payments, and that gross figure often includes tolls, fees, and other amounts that were passed through to riders or paid back to the platform. Your taxable profit is gross income minus deductible business expenses. The expenses are the whole game, and the biggest one is your car.
The car deduction: mileage or actual expenses, never both
You get one choice per vehicle: the IRS standard mileage rate for business miles, or your actual expenses. The mileage method is simpler and usually wins for drivers with older, paid off cars, because it bundles gas, repairs, insurance, and depreciation into one per mile figure set annually by the IRS. The actual expense method can win for a newer financed car with high costs, but it demands meticulous records and a business use percentage for every shared cost.
Whatever method you pick, only business miles count. Miles driven with a passenger, miles driven to pick one up, and miles driven while the app is on and you are waiting for a ride all count as business miles. The drive from your house to the area where you start driving, with no passenger and no app activity, is commuting, and commuting is not deductible. This distinction is where sloppy logs cost drivers. A mileage log needs dates, starting and ending locations, business purpose, and miles. Apps that track this automatically exist, and for a driver doing 15,000 business miles a year, a missing month of logs can mean hundreds of dollars in lost deductions.
| Example, $30,000 gross rideshare pay | Amount |
|---|---|
| Gross payments reported | $30,000 |
| Business miles, 15,000 at an illustrative rate | Minus mileage deduction |
| Phone, tolls, supplies | Minus other expenses |
| Net profit, example with $10,500 total expenses | $19,500 |
| Self-employment tax, 14.13 percent of profit | About $2,755 |
The table is illustrative, and your mileage rate depends on the tax year, but the shape is the point. Expenses cut the tax twice: once against income tax, once against self-employment tax. Every deductible dollar you fail to record costs you roughly 14 cents in self-employment tax plus whatever your income tax bracket adds.
Self-employment tax for rideshare drivers: the quarterly payment habit
Self-employment tax for rideshare drivers is not just an April problem. If you expect to owe more than $1,000 in tax for the year after withholding and credits, the IRS expects quarterly estimated payments, in April, June, September, and January. Miss them and you can owe an underpayment penalty on top of the tax. The practical fix is boring and effective: set aside a percentage of every payout the week you get it. Twenty five to 30 percent covers self-employment tax plus income tax for most part time drivers, and the money is there when the quarter ends instead of being a scramble.
Drivers who also hold a W-2 job have a cleaner option. Increase your W-2 withholding enough to cover the rideshare tax, and the IRS treats withholding as paid evenly through the year, which sidesteps the quarterly deadlines entirely. Run the estimate once, file a new W-4, and stop thinking about quarters. It is the lowest effort path I know for part time drivers.
One last thing that trips people up. Driving for both Uber and Lyft does not create two businesses for tax purposes. It is one Schedule C activity, rideshare driving, with combined income and combined expenses. Keep one log, one expense file, and one profit figure. Simplicity here is not laziness. It is what makes the return defensible when the numbers get checked.
Frequently asked questions
Do Uber and Lyft withhold taxes for drivers? No. Drivers are independent contractors, and no tax is withheld from payouts.
Is the 1099 amount my taxable profit? No. Profit is gross income minus deductible business expenses, and that profit is what self-employment tax applies to.
Do rideshare drivers owe self-employment tax on less than $400 of profit? No. The $400 net earnings threshold applies before Schedule SE is required.
Can rideshare drivers deduct car expenses and mileage both? No. Choose the standard mileage rate or actual expenses for each vehicle, not both.
Do rideshare drivers need to pay quarterly estimated tax? Usually yes once expected tax exceeds $1,000, unless W-2 withholding covers it.
