Side Hustle Taxes is a free calculator built for the roughly 70 million Americans doing gig work, freelancing, or running a side hustle — Doordash, Uber, Instacart, Etsy, freelance work, streaming, Airbnb hosting, pet sitting, and everything else paid on a 1099 instead of a W-2.
Most free calculators either oversimplify (just "set aside 30%") or are buried inside a paid software signup flow. This one shows the actual math using the real 2026 IRS rules, including the 20% QBI deduction that a lot of free tools skip, and it's free to use with no account required.
The site is supported by affiliate links to tax and bookkeeping tools, and by a paid spreadsheet (the Gig Worker Quarterly Tax & Deduction Tracker) for people who want a done-for-you system instead of a one-time calculation. Using the calculator itself never requires a purchase.
This is an independent project, not affiliated with the IRS, TurboTax, QuickBooks, Doordash, Uber, Etsy, or any other company or platform mentioned on this site. See our legal & privacy page for full details, including our affiliate disclosure.
