Key Points on 2024 Social Security Tax Cap
In 2024, the government has set a cap of $168,600 on income subject to Social Security tax, up from $160,200 in 2023. This means the maximum Social Security tax deducted from an employee’s paycheck is $10,453.20, compared to $9,932.40 in 2023.
Before 2023, U.S. employees contributed 6.2% of their income up to $160,200, with employers matching this amount, resulting in a total 12.4% deduction for each employee. Self-employed individuals paid the full 12.4% but could deduct half from their taxes. The Social Security wage base (SSWB) limit, the maximum income subject to this tax, increases annually, starting at $9,000 in 1972.
It’s important to stay informed about the Social Security Tax Limit for 2024 to understand how it may impact your income.
Understanding the Social Security Tax Cap
If your income goes beyond the Social Security wage base, you won’t have to pay Social Security tax on that portion. The cap has increased to $160,200 in 2023 from $147,000 in 2022, making the maximum Social Security tax payment for 2023 $9,932. It’s important to note that this cap specifically applies to the 6.2% Old-Age, Survivors, and Disability Insurance (OASDI) tax, also known as Social Security.
Another payroll tax to keep in mind is the 1.45% Medicare tax on your total income, which rises to 2.35% for income exceeding $200,000. Staying informed about these tax details is crucial for effectively managing your finances.
2024 Social Security Tax Limit
According to recent updates from the Social Security Administration, the income threshold for calculating Social Security taxes is slated to rise from $160,200 in 2023 to $168,600 in 2024. Once your income exceeds this threshold, both self-employment income and wages are no longer subject to Social Security tax.

Under the Federal Insurance Contributions Act (FICA), employers, employees, and self-employed individuals encounter two taxes: one for Old Age, Survivors, and Disability Insurance (commonly known as Social Security tax) and another for Medicare tax, also known as hospital insurance. While there’s no upper limit for Medicare tax, there is a cap on the amount subject to reimbursement for Social Security tax. In 2024, the FICA tax rate for employers will be 7.65%, with 1.45% going to Medicare and 6.2% to Social Security. Keeping abreast of these changes is vital to understanding how they might affect your income.

Evolution of Social Security Tax Limits

Over the last ten years, the federal government has increased the Social Security tax cap in eight out of ten years. The most significant rise occurred in 2023, jumping from $147,000 in 2022 to $160,200 in 2023—an almost 9% increase.

Understanding Social Security Payroll Tax
The main element of payroll taxes, referred to as the Federal Insurance Contributions Act (FICA) taxes, acts as the primary funding source for Social Security. Both employers and employees contribute 7.65% of their salaries to FICA taxes, with the 6.25% Social Security tax applied only up to a designated annual income limit.
Self-employed individuals also contribute to these funds through taxes governed by the Self-Employment Contributions Act (SECA). The notable distinction lies in the rates, as individuals are accountable for both the employer and employee tax under SECA.
