Whether you’re a full-time freelancer or earned $500 on a side project, you need to report it. Here’s exactly how to do it without overpaying or triggering an audit.
Quick answer: Report all freelance income on Schedule C of your tax return. Deduct all business expenses to reduce taxable income. You’ll owe income tax + 15.3% self-employment tax on net profit. Make quarterly estimated payments if you’ll owe $1,000+ at tax time.
With aggressive but legal deductions, the effective tax rate on $75K gross is about 10%.

Bottom Line
Freelance tax filing is straightforward once you know the process: track income and expenses throughout the year, pay quarterly estimates, and file Schedule C with your annual return. The key to keeping taxes low is maximizing legitimate deductions — home office, health insurance, retirement contributions, and equipment can slash your taxable income dramatically. Don’t fear the self-employment tax — most of it is building your own Social Security benefit.
