An employer's federal payroll tax responsibilities include withholding from an employee's compensation and paying an employer's contribution for Social Security and Medicare taxes under the Federal Insurance Contributions Act (FICA).
On top of the income tax, employers also have a legal obligation to reduce your gross pay for Social Security and Medicare taxes. You may see this withholding reported on your pay stub as FICA, which stands for the Federal Insurance Contributions Act.
