Corporations can pay Estimated Income Tax payments online using our free tax portal,
MyDORWAY. Select
Business Income Tax Payment to get started. Do not submit the SC1120-CDP if you pay online.
Corporations can also pay Estimated Income Tax payments electronically through Electronic Funds Transfer (EFT). To get started, the company must register with the SCDOR. The registration process takes up to three weeks. If you are interested in the EFT program, complete and submit a
D-128.
If filing by paper, mail the completed
SC1120-CDP along with payment to:
SCDOR, Corporation Voucher, PO Box 100153, Columbia, SC 29202. Make your check payable to SCDOR. Include your name, FEIN, tax year, and SC1120-CDP in the memo.
Do not send cash.
Your FEIN (Federal Employer Identification Number) is required to ensure proper credit of payments submitted. Providing an incorrect FEIN will result in processing delays and errors in posting the payments.
