General Instructions
Choose your state from the list below to access detailed instructions for both business and personal tax extensions.
South Dakota is one of the few states that does not have a state income tax. Therefore, there is no South Dakota business tax extension. If you received a confirmation email from FileLater indicating that your Federal tax extension has been IRS-approved, there’s nothing more you need to do.
For additional information, please visit the South Dakota Department of Revenue website.
