What It Does
Use the calculator with intent
The Side Hustle Tax Calculator provides an estimate of your federal and state tax obligations specifically for your independent contractor or gig economy earnings. It accounts for income, deductible expenses, and self-employment taxes, giving you a clear picture of what you owe.
This tool is invaluable for anyone earning income outside of a traditional W-2 job, including freelancers, gig workers, online sellers, consultants, and independent contractors.

Start with Side Hustle Net Income Annual. Then compare Self Employment Tax and Incremental Federal Income Tax before deciding what changes the answer most.
Input Steps
Field by field
- 1
Side Hustle Gross Income Annual
Enter side-hustle gross income, deductible business expenses, primary W-2 income, filing status, and any extra deductions that affect taxable income. Keep business expenses strict; personal spending disguised as deductions will understate tax.
- 2
Side Hustle Deductible Expenses Annual
Read side-hustle net income, self-employment tax, incremental federal tax, and the recommended reserve amount. Self-employment tax alone is roughly 15.3% on most net earnings before federal income tax is added.
- 3
Primary W2 Income Annual
Many side hustlers need to reserve about 25%-35% of net profit for federal tax, and more if state tax applies. If the reserve rate shocks you, the business is less profitable than the gross revenue suggests.
- 4
Filing Status
Move the reserve into a separate HYSA every time you get paid and use the quarterly tax planner to map payment dates. If margins are thin, raise prices or cut weak business expenses before adding more work.
- 5
Additional Deduction Annual
Re-run monthly, after a major income spike, or when W-2 income changes brackets. Track net profit, reserve percentage, and whether quarterly payments still line up with the plan.
Run one base case and one sensitivity case before trusting a single output.
