South Dakota is one of the few states without a personal income tax. Therefore, there is no reason for an individual taxpayer to request a South Dakota tax extension. If you received a confirmation email from FileLater indicating that your Federal tax extension has been approved by the IRS, there's nothing more you need to do.
