Side Hustle Income Tax Calculator
Calculate taxes on your side hustle income on top of your W-2 salary
Your side hustle income is taxed at your marginal rate — stacked on top of your salary. Set aside approximately 26% of every side hustle dollar for taxes.
Uses 2026 IRS brackets and standard deduction ($16,100 single / $32,200 MFJ). SE tax applies only to side income. Federal income tax on side income is calculated as the difference between total tax and tax on W-2 alone. The 50% SE tax deduction has been applied. Does not include state taxes or QBI deduction.
Frequently Asked Questions
Do I have to pay taxes on my side hustle income?+
Yes. The IRS taxes all income — whether it's from your main job, freelance work, or a weekend gig. Side hustle income is subject to income tax plus self-employment tax (15.3%). Your W-2 withholdings only cover your main job; you need to account for the additional income separately.
How much tax should I set aside from my side hustle?+
A common rule of thumb is setting aside 25-30% of net side hustle income for federal taxes (income tax + SE tax). However, your actual rate depends on your total income, filing status, and deductions. This calculator gives you the exact number instead of guessing.
Can I deduct side hustle expenses from my taxes?+
Yes. Any ordinary and necessary business expense for your side hustle is deductible: supplies, software, home office, mileage, phone, internet (business portion), marketing, and more. These deductions reduce your net self-employment income, which lowers both your income tax and SE tax.
