This document provides instructions for filing a South Carolina Individual Income Tax Return extension (Form SC4868). It explains that the extension allows an additional six months to file the tax return. Taxpayers have until April 15th (or the original due date of a fiscal year return) to file for the extension. While the extension provides more time to file, it does not extend the deadline for paying any taxes owed. The form and instructions provide guidance on calculating balances due and ensuring payment is submitted on time.
