About This Social Security Tax Calculator (US)
This Social Security tax calculator estimates Social Security tax on wages or self-employment income. It is useful for understanding part of the payroll tax taken from earned income.
Employees usually pay Social Security tax through payroll withholding, while employers also pay a matching share. Self-employed workers generally pay both the employee and employer portions through self-employment tax rules.
Social Security Tax Example
If an employee earns USD 60,000 in wages subject to Social Security tax, the employee share is based on the applicable Social Security rate up to the annual wage base limit.
Income above the wage base is not subject to additional Social Security tax, though it may still be subject to Medicare tax and income tax.
Why the Wage Base Matters
The Social Security wage base can change by tax year. That means high earners may stop paying Social Security tax after wages exceed the annual limit, but regular payroll withholding resumes in the next tax year.
Use this calculator for planning, then confirm current wage base limits and rates with IRS or Social Security Administration guidance.
