How It Works

Ever wonder how much of your side hustle earnings you actually get to keep? Our Side Hustle Income Calculator helps you estimate your net income after deducting self-employment, federal, and state taxes. This is crucial for financial planning and understanding your true profitability, especially with potential tax law changes by 2026.

The calculator first determines your net earnings from self-employment, then calculates self-employment tax (15.3% on the first $168,600 of net earnings for Social Security and 2.9% for Medicare, with the Social Security cap increasing by inflation annually). Next, it estimates federal income tax based on progressive tax brackets (e.g., 10%, 12%, 22% for single filers, adjusted for 2026 inflation) and then applies state income tax rates.

Remember to track all your business expenses meticulously; these deductions significantly reduce your taxable income. Many side hustlers forget about quarterly estimated tax payments, which can lead to penalties if not paid on time. Also, consider setting aside a percentage of each payment for taxes immediately.

Example: Freelance Designer in California

  1. 1 Input: Gross side hustle income: $15,000. Business expenses: $2,000. State: California. Filing Status: Single.
  2. 2 Calculation: Net earnings from self-employment: $13,000. Self-employment tax (estimated): $1,989. Federal income tax (estimated after deductions): $1,100. California state income tax (estimated): $350.
  3. 3 Result: Estimated Net Take-Home Pay: $11,561.
  4. 4 Context: This means for every dollar earned, approximately $0.77 is kept after taxes. This calculation assumes no other income sources and standard deductions. Actual results may vary based on individual tax situations and additional deductions.

Frequently Asked Questions

How much tax do I pay on side hustle income?
Side hustle income is subject to self-employment tax (15.3% for Social Security and Medicare) plus federal and state income tax at your marginal rate. A common mistake is not realizing the SE tax alone takes 15.3% off the top before income tax.
Do I need to pay quarterly estimated taxes on side income?
Yes, if you expect to owe $1,000 or more in taxes from self-employment income. Quarterly payments are due April 15, June 15, September 15, and January 15. Missing these deadlines triggers underpayment penalties.
What expenses can I deduct from side hustle income?
You can deduct ordinary and necessary business expenses: supplies, software, home office (simplified method: $5/sq ft up to 300 sq ft), mileage (70 cents/mile in 2026), internet (business portion), equipment, and professional development directly related to your hustle.
