1. What is Social Security Tax?

Social Security tax is a payroll tax collected to fund the Social Security program in the United States. It's calculated as a percentage of wages up to a maximum taxable amount called the wage base.

The calculator uses the Social Security tax formula:

Where:

• \( Taxable\ Income \) — Employee's gross wages subject to Social Security tax
