South Carolina Request For Voluntary Wage Withholding is a form issued by the South Carolina Department of Revenue used by employers to initiate a voluntary withholding of wages from an employee's paycheck for the purpose of paying taxes. It is a voluntary agreement between the employer and the employee, and is used when an employee has unpaid tax liabilities or is expecting a refund from the state. There are two types of South Carolina Request For Voluntary Wage Withholding forms: Form SCW-1 and Form SCW-2. Form SCW-1 is used for a one-time withholding, while Form SCW-2 is used for a continuing withholding. Both forms must be signed by the employee in order to be legally binding.
