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. Corporate partners and members may not participate in composite returns.

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.

See SC Code Section 12-6-5030​, SC Revenue Procedure ​17-2​.

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 Composite Filer box and mail the original with payment, if any.

See SC Revenue Procedure​ 17-2.
