How Side Hustle Taxes Work

Unlike a W-2 job where taxes are withheld automatically, side hustle income is taxed in two ways: self-employment tax AND income tax.

Self-Employment Tax (SE Tax)

SE tax is 15.3% on your net self-employment income (after expenses). This covers Social Security (12.4%) and Medicare (2.9%). You can deduct half of SE tax from your income, which reduces the income tax portion.

Net SE Income = Side Income − Expenses
SE Tax = Net SE Income × 0.9235 × 0.153
SE Deduction = SE Tax ÷ 2

Do I have to pay taxes on side hustle income under $600?

Technically yes — the $600 threshold only determines whether a client is required to send you a 1099. You're required to report all self-employment income, even if no 1099 is issued.

When do I need to pay quarterly estimated taxes?

If you expect to owe $1,000 or more in taxes after withholding, you must make quarterly estimated payments. Due dates are typically April 15, June 15, September 15, and January 15.
