Side Hustle Tax Calculator 2026

Estimate taxes on your gig, freelance, or side hustle income. See your take-home pay and quarterly payment amount — factoring in your W2 income for accurate bracket placement.

A side hustle tax calculator helps you understand exactly how much of your gig income goes to taxes. If you drive for Uber, deliver for DoorDash, freelance on Upwork, sell on Etsy, or do any side work — the IRS considers this self-employment income. That means you owe self-employment tax (15.3%) plus federal and state income tax on every dollar.

What makes side hustle taxes tricky is how they interact with your main W2 job. Your side income stacks on top of your salary, often pushing into a higher tax bracket. For example, if you earn $60,000 from a W2 job, your side hustle income is taxed at the 22% federal rate — on top of the 15.3% SE tax.
