Social Security Income Limit 2025. That means that the maximum amount of social security tax an employee will pay (through withholding from their paychecks). If you're a high earner, you'll want to keep an eye on social security's maximum taxable.

The tax limit is indexed to inflation and is therefore estimated to rise in 2026. In addition to the benefit increase for 2025 comes a corresponding increase in how much workers will pay into the social security system in the coming year.
