Introduction
Being your own boss comes with many perks—freedom, flexibility, and full control of your business. But it also means taking on the responsibility of calculating and paying self-employment taxes.
Unlike traditional employees, self-employed professionals must handle both the employer and employee portions of Social Security and Medicare taxes, plus income tax. And without a clear picture of your tax obligations, you could end up overpaying—or worse, underpaying and facing penalties.
Our Self-Employment Tax Calculator simplifies the process with two modes:
- Quick Mode – Estimate taxes with a few basic inputs
- Advanced Mode – Factor in detailed business expenses and deductions for accurate results

What Are Self-Employment Taxes?
In the U.S., self-employment tax includes:
- Social Security Tax (12.4%)
- Medicare Tax (2.9%)
- An additional 0.9% Medicare surtax may apply for high earners
That totals 15.3% of your net earnings, not gross income. This is on top of any federal and state income tax owed.
These taxes apply to freelancers, gig workers, consultants, small business owners, independent contractors, and other self-employed individuals.
