For 2025, the Social Security Administration (SSA) established the maximum amount of taxable Social Security earnings at $176,100. It’s the most in income that’s subject to the Social Security payroll tax, now 6.2% for employees and employers, and combined 12.4%. It rose from $168,600 in 2024 due to adjustments for inflation and wage growth.
Background on Social Security tax limits
The wage base or Social Security tax ceiling has been raised each year to continue funding the Social Security program. The tax rate has not changed since 1990, but the wage base has risen to cover increased wages and inflation over the years. This is to keep the Social Security program solvent, which distributes benefits to millions of Americans.
How Social Security tax works
- Tax rate: Workers pay 6.2% of their salaries toward Social Security, while employers pay an additional 6.2%, totaling 12.4%.
- Tax limit: Only earnings up to $176,100 are taxable for Social Security in 2025. Income beyond this does not get taxed for Social Security purposes.
- Medicare tax: Social Security does not have a wage base limit on Medicare taxes. Both employers and employees each contribute 1.45% of all wages earned, and an additional 0.9% for employees who earn more than $200,000 ($250,000 for joint filers).
For those who earn above the $176,100 threshold, the highest Social Security tax paid in 2025 is $10,918.20. The threshold can lead to substantial tax savings for high earners since income above the threshold is not taxed under Social Security.
Annual adjustments and COLA
The SSA also charges an annual COLA to offset Social Security benefits due to inflation. For 2025, the COLA will be 2.5%, which translates into more money for beneficiaries in their monthly benefits. The adjustment ensures that Social Security benefits keep up with the cost of living.
Impact of wage base increases
The yearly expansion of the wage base keeps more earnings covered under Social Security, keeping the program funded. It also keeps taxpayers paying more Social Security taxes if their income is higher than last year’s threshold.
The maximum taxable earnings for Social Security in 2025 is $176,100, another attempt to align the program with the evolving economy. Knowing such figures will always be important to employers and taxpayers alike to balance their tax payments and future Social Security benefits and contributions. As the constantly changing U.S. economy continues to advance, readjusting the wage base of Social Security will always be important when it comes to the long-term solvency of the program.
