Social Security taxable wage base increases to $176,100 in 2025
The Social Security Administration (SSA) has announced significant updates for Social Security beneficiaries and workers in 2025, including a cost-of-living adjustment (COLA) and an increase in the taxable wage base.
These changes will impact millions of retirees and workers across the country.
Cost-of-living adjustment for Social Security recipients
Starting in January 2025, over 68 million retirees who receive Social Security benefits will see a 2.5 percent COLA increase in their payments. This adjustment will lead to an average increase of approximately $50 per month for retirees.
Additionally, nearly 7.5 million people receiving Supplemental Security Income (SSI) will experience the same percentage increase in their payments starting on December 31, 2024. For those who receive both Social Security and SSI benefits, both payments will rise accordingly.
The SSA has noted that the annual COLA has averaged 2.6 percent over the last decade, with a 3.2 percent adjustment in 2024.
Higher wage earners to pay more in payroll taxes
While retirees celebrate the increase in benefits, higher wage earners will see an increase in the Social Security wage base – the amount of income subject to payroll taxes. In 2025, this wage base will increase to $176,100, up from $168,600 in 2024.
This change means that higher-paid workers and their employers will contribute more to the Social Security trust fund in 2025.
Breakdown of payroll taxes in 2025
Workers are familiar with the Federal Insurance Contributions Act (FICA) taxes, which fund both Social Security and Medicare.
Here’s a breakdown of how these taxes are applied:
Social Security tax (12.4 percent): This portion applies to earnings up to the wage base of $176,100 in 2025.
- Employees pay 6.2 percent of their earnings up to this wage base, and their employers match this contribution.
- Self-employed taxpayers are responsible for both portions, paying the full 12.4 percent.
Medicare tax (2.9 percent): This portion has no income cap, meaning it applies to all earnings.
- Employees contribute 1.45 percent from their wages, while employers match this amount.
- Self-employed individuals must pay both the employer and employee shares, totaling 2.9 percent.
Impact of wage base increase
To put it into perspective, let’s look at how the increased wage base impacts taxpayers in 2025:
- In 2024, a worker earning at or above the wage base of $168,600 paid $10,453.20 in Social Security taxes (calculated as $168,600 x 6.2 percent).
- In 2025, with the wage base rising to $176,100, the maximum Social Security tax will be $10,918.20 (calculated as $176,100 x 6.2 percent).
This change means that higher-paid workers could contribute an additional $465 to the Social Security trust fund next year.
Additional Medicare surtax for high earners
While the Social Security tax caps out at the wage base, higher earners may face an additional 0.9 percent Medicare surtax under the Affordable Care Act (ACA).
This surtax applies to:
- Single filers earning more than $200,000 per year.
- Married couples filing jointly earning more than $250,000 per year.
Unlike Social Security taxes, there is no income cap for the Medicare tax, so high earners continue to pay the 1.45 percent standard Medicare tax on all earnings, plus the ACA surtax on income exceeding the threshold.
Social Security wage base adjustments and COLA
The Social Security wage base adjustments are often viewed as part of a broader cost-of-living adjustment.
While the wage base itself is not indexed for inflation, the SSA uses a specific formula to ensure that Social Security benefits keep pace with inflation, which results in these annual increases.
Although beneficiaries may feel that the 2.5 percent increase in payments doesn’t cover rising costs, the SSA’s annual COLA aims to help retirees cope with inflation.
Conclusion
The SSA’s announcements for 2025 bring both benefits and responsibilities. Retirees will enjoy a 2.5 percent increase in their Social Security payments, while higher earners will see more of their income subject to payroll taxes. Understanding these changes is essential for planning and preparing for the upcoming year.
