The Bottom Line

Freelancers typically owe 25-35% of net income in combined taxes. Reduce your bill by tracking all deductions (home office, health insurance, vehicle, software), contributing to a Solo 401(k) or SEP IRA, and paying quarterly estimates to avoid penalties. Set aside 30% of every payment you receive, and you’ll never be caught short at tax time.
