Self Employment Tax Calculator - Formula

SE Tax = Net Earnings × 92.35% × 15.3% (12.4% SS + 2.9% Medicare)

Self-employed individuals pay both the employer and employee share of FICA taxes, totaling 15.3%. The taxable base is 92.35% of net earnings (to simulate the employer deduction). An additional 0.9% Medicare surtax applies above $200,000 (single) or $250,000 (married filing jointly). Half of SE tax is deductible on your income tax return.
