South Carolina Tax Extension

The income tax returns for residents of the Palmetto State are due by April 15 (for most taxpayers).

However, if you cannot meet this deadline, you can request a six-month tax extension from the South Carolina Department of Revenue. Note that you must submit your extension request by the original filing due date of your return (April 15th).

If you owe zero state income tax and you have a valid Federal tax extension (IRS Tax Form 4868), the state of South Carolina will automatically grant you a state tax extension. In this case, you do not need to file a separate state extension request or send in a copy of your Federal extension form.

If you owe state income tax and/or you did not receive a Federal tax extension, use South Carolina Tax Form SC4868 (Request for Extension of Time to File South Carolina Individual Income Tax Return).

Remember that a tax extension does not extend the time you have to pay your income tax due. Make sure to submit Form SC4868 by April 15th in order to avoid penalties and interest charges.

Mail Form SC4868 (with payment, if applicable) to the following address:
SC Department of Revenue, Income Tax, Columbia, South Carolina 29214-0013
