Policy Statement

Payroll Services will process payroll tax deductions imposed by federal, state and local laws for all employees of the university. Employees who are subject to FICA taxes (Social Security, Medicare, and Additional Medicare taxes) will be taxed at the applicable rate defined for the respective tax year. All other federal, state, and local taxes will be withheld at the applicable rates or as defined by withholding tables or regulations of the respective taxing authority.

Mandatory Payroll Tax Forms

The following tax forms must be submitted via SelfService in ConnectCarolina:
