General information: S Corporations are required to withhold 5% of the South Carolina taxable income of shareholders 
who are nonresidents of South Carolina. 
 
Due dates: To avoid penalty and interest, file the SC1120S-WH and submit your Withholding Tax payment by the 15th 
day of the third month following the S Corporation’s taxable year end. No extension of time to file or pay can be  
granted for the SC1120S-WH. For more information, refer to SC Code Section 12-8-590(A), available at 
dor.sc.gov/policy. 
 
Payments: Pay online using our free tax portal, MyDORWAY, at dor.sc.gov/pay. Select Business Income Tax 
Payment to get started. Payments of $15,000 or more must be submitted electronically according to SC Code Section 
12-54-250. 
 
The SC1120S-WH cannot be filed electronically. 
 
If you pay on MyDORWAY, you must still mail your completed SC1120S-WH to: 
 
SCDOR 
Corporate Taxable  
PO Box 100151 
Columbia, SC 29202 
 
If you pay by check, make payable to SCDOR and include your business name, FEIN, and SC1120S-WH in the memo. 
 
Line instructions: 
 
Heading: Enter the FEIN and Income Tax period ending date of your S Corporation.  
 
Enter the name and mailing address of your S Corporation. 
 
Line 1: Enter the South Carolina income taxed to the shareholders of your S Corporation. This amount is on line 7 of 
your SC1120S. Reduce the line 7 amount by any income that was directly allocated to the shareholders. If you are  
requesting an extension of time to file your SC1120S, estimate the amount of South Carolina taxable income on line 1  
of the SC1120S-WH. There is no extension of time to file the SC1120S-WH. 
 
Line 2: Enter the amount of income from line 1 that is taxable to nonresident shareholders. 
 
Line 3: Enter the income allocated to nonresident shareholders but exempt from withholding. Nonresident  
shareholders are exempt from withholding if they: 
 •      have provided an I-309 affidavit,  
 •      are included on a composite Individual Income Tax return, or 
 •      are a tax exempt entity 
Include the I-309 Nonresident Shareholder Affidavits and the I-338 Composite Return Affidavits if they have not  
previously been filed with the SCDOR. 
 
Line 4: Subtract the amount on line 3 from the amount on line 2. This is your South Carolina income subject to  
withholding. 
 
Line 5: Multiply line 4 by 5%. This is the amount of Withholding Tax due. 
 
Line 6: Enter the amounts withheld on an I-290 or passed through from other entities on a 1099-MISC. If claimed here,  
do not claim on your SC1120S. 
 
Line 7: Subtract the amount on line 6 from the amount on line 5. This is your balance due. 
 
What to do after you file the SC1120S-WH: Provide nonresident shareholders a federal 1099-MISC with “South  
Carolina only” written at the top. The 1099-MISC should show the amount of income allocated to the nonresident  
shareholders and the tax withheld on their behalf. The 1099-MISC must be provided to nonresident shareholders by the 
15th day of the third month following the taxable year end of the S Corporation. The nonresident shareholder must 

attach a copy of the 1099-MISC to their Income Tax return to claim credit for the withholding. The shareholder cannot 
use an SC1120S K-1 to claim withholding on their Income Tax return. 
 
You cannot amend the SC1120S-WH to reduce the withholding amount after the original due date of the return.  
Report the amount of withholding to the shareholders on the 1099-MISC. The shareholders will claim any refunds due  
on their Income Tax returns. 
 
Sign and date your return: The return must be signed by an officer of the corporation who is duly authorized to make   
the report on behalf of the corporation.
