How FICA and Payroll Taxes Work: Social Security and Medicare

See how Social Security and Medicare taxes are calculated, who pays them and why employer matching matters.

3 min read · Updated 2026-10-03

FICA, the Federal Insurance Contributions Act, funds Social Security and Medicare. It appears on your pay stub as separate lines.

The rates

Employees pay 6.2% for Social Security on wages up to $184,500 in 2026 and 1.45% for Medicare on all wages. Employers pay the same amounts. High earners pay an additional 0.9% Medicare tax on wages above $200,000, with no employer match.

Self-employment

Self-employed workers pay both halves, totaling 15.3% on net earnings, though half is deductible when calculating income tax.

Why it matters

FICA is separate from income tax and is not reduced by the standard deduction. Pre-tax health premiums and cafeteria plan contributions may be exempt from FICA, boosting their value. Your earnings record determines your future Social Security benefit.

Try the numbers

Use our FICA & Payroll Tax Calculator to see this in practice. With its default example (Annual wages: $110,000), it shows employee fica: $8,415. Adjust the inputs to match your situation.

Key takeaways

  • Employees pay 7.65% up to the Social Security wage base.
  • Employers match; the self-employed pay both halves.
  • Some pre-tax benefits also avoid FICA.
