Self-Employed? Your Real Payroll Cost Is More Than Your Own Paycheck

As a self-employed business owner, there's no employer withholding Social Security and Medicare for you โ€” instead, you pay Self-Employment (SE) tax, which covers both the "employee" and "employer" shares at a combined 15.3% (12.4% Social Security up to the annual wage base, plus 2.9% Medicare with no cap, plus an extra 0.9% Additional Medicare Tax above $200,000). If you hire employees, you also become responsible for matching 7.65% of each employee's wages in FICA taxes on top of the wages themselves. Add in health insurance โ€” which the self-employed typically buy on their own through the ACA Marketplace since there's no employer plan โ€” and the real cost of running your business is significantly higher than the paycheck numbers alone suggest.
