Social Security Tax = min(Income, $184,500) × 6.2%
Medicare Tax = Income × 1.45%
Additional Medicare Tax = max(0, Income − Threshold) × 0.9%
Total FICA (Employee) = Social Security Tax + Medicare Tax + Additional Medicare Tax
For self-employed individuals, the calculator applies the self-employment tax rate of 15.3% (12.4% for Social Security + 2.9% for Medicare) on the first $184,500 of income, with Medicare tax on all income.
