Social Security Payroll Tax is One Part of the FICA Payroll Tax
The Social Security payroll tax is one of the two components of the FICA payroll tax. The other component is the Medicare tax which applies to every dollar of an employee's earnings. In other words, there is no wage limit or cap for the Medicare tax. In fact, there is also a Medicare surtax that applies to high income employees.
An Employer Must Match its Employees' FICA Taxes
In addition to the employees' Social Security and Medicare payroll taxes, the employer is required to match the amounts that were withheld from the employees' paychecks (other than the Medicare surtax).
