Driving for Uber, Lyft, or delivering for DoorDash in 2026 is a great way to earn on your own terms. However, the “gross pay” you see in your app isn’t what you actually take home. As a gig driver, you are an independent contractor. Specifically, this means the IRS views you as a small business owner. Therefore, knowing how to use an Uber & DoorDash tax estimator is the first step to avoiding a massive tax bill in April.
The Step-by-Step Calculation of Self-Employment Tax
Every delivery and every ride triggers what’s known as the Self-Employment (SE) tax. Specifically, this tax covers your Social Security and Medicare contributions. For the 2026 tax year, the projected rate remains at 15.3%.
In fact, the IRS requires you to pay this on your net profit, not your total app earnings. For this reason, you must subtract your business expenses before calculating the tax. You can find a deeper breakdown in our 2026 1099 Self-Employment Tax Guide.
The basic formula is:
- Gross App Earnings – Business Expenses (Mileage, etc.) = Net Profit
- Net Profit × 92.35% (to account for the employer-equivalent portion)
- Result × 15.3% = Your Estimated Self-Employment Tax
Note: The IRS allows you to deduct the employer-equivalent portion of Self-Employment tax, which is why only 92.35% of net profit is subject to SE tax.
Mileage: The Ultimate Tax Shield (Based on IRS Publication 463)
For most drivers, the vehicle is the biggest deduction. Based on the guidelines outlined in IRS Publication 463, you generally have two ways to lower your taxable income. You can compare these in detail using our Standard vs. Actual Expenses Calculator.
- Standard Mileage Rate: This is the easiest method. For 2026, the estimated IRS mileage rate covers gas, repairs, and insurance in one simple cent-per-mile figure. You multiply your business miles by the rate, and you deduct that amount from your income.
- Actual Expenses: Alternatively, you can track every penny spent on gas, tires, oil changes, and even car washes. However, you must choose one method and stick to it for the entire year.
Real-Life Example: If you earned $50,000 on Uber but drove 30,000 business miles, the 2026 IRS Mileage Deduction Calculator could show you how to wipe out nearly $20,000+ of your taxable income. As a result, you only pay tax on the remaining profit—see your exact numbers with our 2026 Uber & DoorDash Tax Estimator.

How to Use the 2026 Uber & DoorDash Tax Estimator
Because Uber and DoorDash do not withhold taxes, you are responsible for making quarterly estimated tax payments. Consequently, if you expect to owe more than $1,000 in total federal tax liability, you are generally required to make quarterly estimated payments.
Rather than guessing your payment, you can use our 2026 Uber & DoorDash Tax Estimator to get a precise number based on your actual miles driven.
