Partnership Income Tax

South Carolina taxable income of a partnership is the same as federal partnership taxable income with certain South Carolina modifications. Multi-state partnerships must directly allocate certain items and apply an apportionment ratio to the remaining income (loss) of the partnership. Taxable income (loss) of a partnership flows through and is taxable to the partners in the same manner as for federal partnership income.

South Carolina income taxable to nonresident partners is subject to withholding by the partnership at a 5% rate. Nonresident partners providing affidavits of their intention to file or who are included in a composite return filed by the partnership on behalf of all of its nonresident partners are exempt from the withholding requirement.

​Use the SC1065ES, Partnership Declaration of Estimated Income Tax, to make quarterly Estimated Tax payments for your Partnership. Pay online using our free online tax portal, MyDORWAY, at dor.sc.gov/pay. Select Business Income Tax Payment to get started. Do not submit the SC1065ES if you pay online. ​If filing your SC1065ES by paper, make your check payable to SCDOR and include your name, FEIN, tax year, and SC1065ES in the memo. Do not send cash. Mail your SC1065ES and payment in one envelope. Partnerships are not subject to underpayment penalties.
