What Is the Social Security Payroll Tax Cap?

The Social Security payroll tax is a mandatory tax imposed on wages to fund the Social Security program. However, there’s a cap on taxable earnings, meaning individuals only pay Social Security tax on income up to a certain threshold.

For 2025, this cap is set at $176,100, up from $168,600 in 2024. This means that earnings above this amount are not subject to Social Security tax. However, Medicare taxes continue to apply to all wages with no cap.

Understanding the Payroll Tax System

The payroll tax system is a crucial component of how Social Security is funded. Employees contribute 6.2% of their wages, which is matched by their employer, making the total Social Security tax 12.4%. Self-employed individuals must cover both portions, leading to a 12.4% tax on earnings up to the wage base limit.

Additionally, Medicare taxes apply at a rate of 1.45% for both employees and employers, with an additional 0.9% Medicare tax levied on individuals earning over $200,000 ($250,000 for married couples filing jointly).
