Quick answer
Side hustle income is self-employment income: you owe regular income tax plus 15.3% self-employment tax on net earnings over $400 a year. Set aside 25–35% of every payment, make quarterly estimated payments if you'll owe $1,000 or more, and deduct legitimate business expenses.
If you earn money from a side hustle, freelancing, or gig work, the IRS considers you self-employed — and that comes with tax obligations most people don't expect. The #1 mistake new freelancers make is not setting aside money for taxes and getting hit with a surprise bill in April.
Self-Employment Tax: The Hidden 15.3%
As a W-2 employee, your employer pays half of your Social Security and Medicare taxes. As a self-employed worker, you pay both halves:
- Social Security: 12.4% (on first $184,500 of earnings in 2026)
- Medicare: 2.9% (no income limit)
- Total self-employment tax: 15.3%
This is in addition to your regular federal and state income taxes. So if you're in the 22% federal bracket plus 5% state, your total effective tax rate on side hustle income is roughly 37–42%.
How Much to Set Aside
A safe rule of thumb: set aside 25–35% of every dollar you earn from self-employment. Put it in a separate savings account and don't touch it.
| Side Hustle Income | Set Aside (30%) | Approximate Take-Home |
|---|---|---|
| $1,000/month | $300 | $700 |
| $3,000/month | $900 | $2,100 |
| $5,000/month | $1,500 | $3,500 |
Quarterly Estimated Tax Payments
If you expect to owe $1,000+ in taxes, the IRS requires quarterly estimated payments. Due dates:
- Q1: April 15
- Q2: June 15
- Q3: September 15
- Q4: January 15 (of the following year)
Missing these deadlines results in penalties and interest. Use IRS Form 1040-ES to calculate and pay.
Tax Deductions That Lower Your Bill
Self-employed workers can deduct legitimate business expenses, reducing taxable income:
- Home office deduction: $5/sq ft, up to 300 sq ft ($1,500 max), or actual expenses
- Internet and phone: Business-use percentage
- Equipment: Computer, software, tools related to your work
- Vehicle mileage: 67 cents/mile for business driving (2026)
- Health insurance premiums: 100% deductible if self-employed
- Retirement contributions: SEP-IRA allows up to 25% of net self-employment income
- Self-employment tax deduction: You can deduct 50% of your SE tax from your income
