The starting point in determining South Carolina taxable income is the corporation's federal taxable income. There are different tax rates for certain organizations. If you are filing:
In order to claim tax withheld from another source, the corporation(s) must include with the return a 1099-MISC, W2 or I-290 form(s). If this is an S Corporation, you must provide nonresident shareholders a 1099 MISC with “South Carolina Only” written at the top showing the amount of income paid and SC tax withheld from the nonresident shareholder. (Code Section
12-8-590). The department does not accept South Carolina Schedule K-1, Partner Information SC1065 or Settlement Statement. See Code Section
12-8-590(D) and Code Section
If the withholding statement is not provided with the return, the amount will be disallowed and an assessment issued if applicable. If you do not respond within 90 days from the date of assessment, you will have waived your right to appeal.

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.
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 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).
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. There is no need to 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 must compute the tax separately on each participant's share of income and add the tax together to arrive at the total tax due.
The methods available depend on whether the partner, shareholder or member has filed an
I-338 Composite Return Affidavit with the department 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 composite return must be signed by an authorized partner, an authorized officer of the S corporation, or an authorized member of the LLC. Attach a schedule showing the separate computations. Total the separate tax amounts and enter on the "tax" line of
SC1040, page 1.
Nonresident fiduciaries and individuals who are shareholders or partners may participate in the filing. All participating taxpayers must have the same tax year.
