• IRS W-4

    The Internal Revenue Service (IRS) has changed the format of the 2020 W-4 Employee Withholding Certificate.  Employees who want to adjust their Federal withholding for tax year 2020 must complete the new version of the form. 

    For help and instructions with the new form, visit the IRS FAQ page.  The IRS has also created an online withholding estimator that can assist you in determining the amounts needed for the new form.

    Any changes submitted on this form will only impact your federal withholding amounts.  See below for instructions to change to your South Carolina withholdings.

     

    SC W-4

    Prior to calendar year 2020, South Carolina did not have a separate W-4 form.  Due to the changes in the IRS form listed above, South Carolina has created a new SC W-4 Withholding Certificate.  All employees who want to make changes to their SC withholding amounts must submit this new version to payroll.  This form will not impact your Federal tax withholding.  This form will only change your South Carolina withholding amount.

     

    Employees are not required to submit either new form unless they want to make a change to future withholding amounts.
