Side Hustle Taxes: What You Owe on Extra Income in 2026
Made money from a side hustle? Here is exactly what you owe in taxes and how to avoid penalties.
Any income over $400 from self-employment (freelancing, gig work, Etsy, content creation) is subject to self-employment tax (15.3%) plus income tax at your marginal rate. If you made $10,000 from a side hustle and your marginal rate is 22%, you owe approximately $3,730 in total taxes on that income.
The Self-Employment Tax Surprise
As an employee, your employer pays half of Social Security and Medicare (7.65%). As self-employed, you pay BOTH halves: 15.3%. This is on top of income tax. Many new freelancers are shocked by their first tax bill because they did not account for this.
How to Reduce Your Tax Bill
Deduct business expenses: home office (simplified: $5/sq ft up to 300 sq ft = $1,500), internet (business percentage), equipment, software, supplies, mileage ($0.67/mile in 2026). Contribute to a SEP-IRA (up to 25% of net self-employment income). Make quarterly estimated payments to avoid penalties (due April 15, June 15, September 15, January 15).
