You can also request your extension by paying your balance due on South Carolina's free online tax portal, MyDORWAY (Select Individual Income Tax Payment to get started, no additional form or paperwork is required). When you file your South Carolina return, answer Yes to the question asking if you filed a 2025 extension on the SC General Information screen.
