W-4 Tax Forms
The Internal Revenue Service (IRS) has changed the format of the W-4 Employee Withholding Certificate.
South Carolina W-4
Prior to the 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.
How do I change my federal and state withholding amounts? Answer: Submit both forms listed above to Payroll.
What if I am a new-hire who has not submitted either form? Answer: The payroll system will default your withholding for both tax agencies to the maximum allowed until you submit a form instructing us to change your withholding.
