A composite return is a single return filed by a partnership, S Corporation, or Limited Liability Company (LLC) taxed as a partnership or S Corporation on behalf of two or more nonresident participants.
A composite return allows S Corporations or Partnerships to compute and report the SC income and tax attributable to electing nonresident shareholders or partners on a single tax return (SC1040 Individual Income Tax Return). Participants are limited to individuals, trusts or estates who are partners of the Partnership, shareholders of the S Corporation or members of an LLC taxed as an S Corporation or Partnership.
A composite return is filed using an
SC1040 SC Individual Income Tax Return. The heading states the name, address, and FEIN of the Partnership, S Corporation or LLC. Do not use "Composite Return for" or "Shareholders/Partners of" in the name. Mark the box for filing
a Composite Return. Mark
Single filing status.
NOTE: Corporate partners and members may not participate in composite returns.
A partnership, S Corporation, or LLC taxed as a Partnership or S Corporation computes the tax separately on each participant's share of income. The methods available for computing the tax depend on whether the partner, shareholder, or member has filed an I-338 Composite Return Affidavit with the SCDOR through the Partnership, S Corporation, or LLC. An I-338 affidavit states that the partner, shareholder, or member has no other income taxable to South Carolina. The tax amounts computed for each participant in the composite return are added together to arrive at the total tax due.
Refer to the
I-338 and the I-348 for more information.
See S.C. Code Section
12-6-5030 and SC Revenue Procedure
File the SC4868 to extend the time to file a composite return. Do not use the SC1120T or the federal form 7004. Extending the time to file a composite return does not extend the time to file the South Carolina S corporation (SC1120S) or partnership (SC1065) return.
Any tax estimated to be due must be paid with the timely filed extension.
Request your extension to file by paying your balance due on our free tax portal, MyDORWAY, at
dor.sc.gov/pay. Select Individual 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 SC4868 by paper, mark the

Yes. If your corporation is dormant or you do not have any income or business to report in an accounting period, you are still required to file a Corporate Tax return, including the annual report (Schedule D; which is part of the Corporate Tax return) and pay any tax or License Fee due each year by the due date of your return. There is a minimum $25 License Fee due annually.
If you do not have any income or business activity, a South Carolina Corporate Tax Return is still required to be filed from the date the charter/authority is granted with the South Carolina Secretary of State (SCSOS) through the date of voluntary dissolution/withdrawal recorded with the SCSOS.
If you have discontinued your business, it is necessary to file the dissolution papers (domestic corporations) or withdrawal documents (foreign corporations) with the SCSOS.
A short period return will be required if the corporation registers before the fifteenth day of the month. Other reasons for a short period return include: new corporation filing, accounting period change, or for a corporation that has dissolved.
Failure to file all returns can result in your account being forfeited by the SCSOS.
Instructions for dissolution, merging, or authorization for withdrawal are available from the SCSOS
online or at 803-734-2158.
If you have discontinued your business, the SCDOR will close your corporate account. File a final Corporate Tax return with an Income Tax period end matching the stamped recorded dissolution date received from the SCSOS. A domestic corporation remains in business until it closes its account with the SCSOS, and a foreign corporation may not withdraw from the State until it obtains a certificate of withdrawal from the SCSOS. See SC Code Sections 33-14-103 and
33-15-200 for more information.

Do not file the final return with SCDOR until the corporation has been dissolved or withdrawn with the SCSOS.
