Do I need to include my federal tax return with my South Carolina state tax return?

No, you do not need to include your federal tax return with your South Carolina state tax return. The South Carolina Department of Revenue does not require a copy of your federal return when filing your state taxes. However, it is important to note that your federal tax information may be used to verify the accuracy of your state tax return. Therefore, it is recommended to keep a copy of your federal return for your own records. Additionally, if you are filing your state tax return electronically, you may be prompted to enter information from your federal return, such as your adjusted gross income (AGI), as part of the e-filing process.
