Social Security Tax Limit for 2024 in the US

The Old Age, Survivors, and Disability Insurance (OASDI) tax, commonly referred to as the Social Security Tax, is a critical component of the United States’ social safety net. This tax, which is a percentage of gross earnings, is mandatory for employees, employers, and self-employed individuals.

Its primary purpose is to fund the Social Security programs administered by the Social Security Administration (SSA). These programs provide financial support to retirees, disabled individuals, and survivors of deceased workers. Understanding the Social Security Tax limit is crucial for all taxpayers as it determines the maximum income subject to this tax each year.

Social Security Tax

The Social Security Tax, established by the Federal Insurance Contribution Act (FICA) in 1935, requires employees and employers to contribute a portion of their earnings to fund Social Security benefits. Additionally, self-employed individuals must pay both the employee and employer portions of the tax under the Self-Employment Contribution Act (SECA).

The OASDI tax rate for 2024 is set at 6.2% for employees and employers, and 12.4% for self-employed individuals. This dual contribution system ensures that the Social Security Trust Fund remains solvent and capable of supporting eligible beneficiaries.

2024 Social Security Tax Limit

For 2024, the Social Security Tax limit has been set at $168,600, an increase from the $160,200 limit in 2023. This means that income above $168,600 is not subject to the 6.2% Social Security payroll tax for employees and employers.

For example, an individual earning $168,600 or more will contribute a maximum of $10,453.20 to the OASDI program in 2024. In contrast, self-employed individuals will contribute up to $20,906.40, as they are responsible for both the employee and employer portions of the tax.

Understanding the Impact of the Tax Limit

The Social Security Tax limit ensures that there is a cap on the amount of earnings subject to the tax, which helps to balance the funding of the Social Security Trust Fund with the benefits paid out. The tax collected is used to provide monthly benefits to retirees, disabled individuals, and survivors.

In 2024, eligible individuals can expect a monthly check of $943, while married couples may receive $1,415. Disabled citizens meeting the eligibility criteria can receive a monthly aid of $1,537.

Historical Changes in the Social Security Tax Limit

The Social Security Tax limit is adjusted annually based on national average wage index changes. This ensures that the tax limit keeps pace with inflation and wage growth. Over the years, the tax limit has seen significant changes:

These adjustments reflect the SSA’s commitment to maintaining the program’s financial health while ensuring that contributions are equitable and sustainable.

Cost of Living Adjustments (COLA)

Each year, the SSA implements Cost of Living Adjustments (COLA) to Social Security benefits. COLA is designed to offset the impact of inflation on benefit payments.

For 2024, the COLA increase is 3.2%, based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). This adjustment helps ensure that beneficiaries maintain their purchasing power as the cost of living rises.

Eligibility for Maximum Social Security Benefits

To maximize Social Security benefits, individuals must consider their income and the age at which they retire. The maximum monthly Social Security benefit for a person retiring at full retirement age in 2024 is $4,873.

However, if an individual retires at the full retirement age, they are eligible for a monthly benefit of $3,822. It’s important to note that the benefit amount depends on the individual’s earnings history and the age at which they start receiving benefits.


Exemptions from Social Security Tax

Not all individuals are required to pay Social Security taxes. Certain exemptions apply, including:

  • Non-resident aliens: Individuals who are neither U.S. citizens nor legal residents and are temporarily residing in the country, such as students.
  • Foreign government employees: Non-resident aliens working in the U.S. for a foreign government are also exempt from Social Security taxes.

These exemptions ensure that only those who are part of the U.S. workforce contribute to the Social Security system.
