Summary:
If the corporation has a valid Subchapter S election granted by the Internal Revenue Service and is doing business in South Carolina, the
SC1120S must be filed.
S Corporations are subject to an annual License Fee of .1% of capital and paid-in-surplus, plus $15. The License Fee cannot be less than $25. Both the Income Tax and License Fee are reported on form SC1120S.
Request your extension to file by paying your balance due on our free online tax portal, MyDORWAY, at
dor.sc.gov/pay. Select Business Income Tax Payment to get started. Your payment on MyDORWAY automatically submits your filing extension request. No additional form or paperwork is required. If filing the
SC1120-T by paper, be sure to include the name of the corporation and FEIN in the memo line of the check or money order. Attach payment to the form and mail to the address on the form. There is no extension of time for payment of Corporate Income Tax or License Fee. Any Income Tax or License Fee due must be paid by the due date to avoid late penalties and interest. This extension request only extends time to file the SC1120S return and does not extend the SC1120S-WH, Withholding Tax on Income of Nonresident Shareholders.
S Corporations are required to withhold 5% of the South Carolina taxable income of shareholders who are nonresidents of South Carolina. 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. Refer to SC Code Section 12-8-590(A). 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 the address on the form.
Form SC1120S-WH must be submitted separately from the SC1120S for processing purposes.
The S Corporation must provide each nonresident shareholder a 1099-MISC form with the verbiage “South Carolina Only” written at the top. This form must show the respective amount of state income and tax withheld.
The S Corporation does not need to withhold on behalf of any shareholder participating in a composite return. Shareholders participating in a composite return do not need to pay Estimated Tax. A non-resident shareholder may provide the S Corporation with an affidavit, Form I-309, agreeing that they will pay and be individually responsible for any SC tax, interest, and/or penalties which may be due. The S Corporation may attach such affidavit to the SC1120S-WH and the S Corporation would therefore, not be required to withhold Income Tax on behalf of such shareholder. If an affidavit has been previously filed, it should not be resubmitted.
