Use the
SC1120-CDP to file and pay your quarterly Estimated Income Tax payments. Pay online using our free online tax portal, MyDORWAY, at

Business Income Tax Payment to get started. Do not submit the SC1120-CDP if you pay online.
If filing your SC1120-CDP by paper, make your check payable to SCDOR and include your name, FEIN, tax year, and SC1120-CDP in the memo. Do not send cash. Mail your SC1120-CDP and payment in one envelope to the address on the form.
