What Is the Social Security Payroll Tax Cap?

For 2025, the cap is $176,100, up from $168,600 in 2024. Any earnings above this amount are not taxed for Social Security purposes, but Medicare taxes continue to apply to all wages.

The tax rate remains 6.2% for employees and employers, totaling 12.4% in combined contributions. Self-employed individuals pay both portions, resulting in a 12.4% tax rate on their income up to the cap.
