Request your extension to file by paying your balance due on our free online tax portal, MyDORWAY, at
dor.sc.gov/pay. Select Business 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 your SC1120-T by paper, make your check payable to SCDOR and include your name, FEIN, Income Tax period ending, and SC1120-T in the memo. Do not send cash. Mail your SC1120-T and payment in one envelope to the address on the form.
There is no extension of time to pay. Any tax due must be paid by the due date to avoid late penalties and interest.

SC990-T if you requested a South Carolina or federal extension.
