The State of South Dakota does not have a state income tax. Therefore, the State of South Dakota’s personal income tax extension is not required. 

Although the State of South Dakota does not require a personal income tax extension, the IRS still requires you to file Form 4868 by the original due date to get an additional 6-month automatic extension of time to file your 1040 personal income tax return.  If you received a valid federal extension from the IRS by filing Form 4868, there is nothing else required of you. 

If you have not yet filed your federal extension, complete Form 4868 with Expressextension in Minutes. 

For additional information, including other taxes that may apply to you, please visit the South Dakota State Comptroller's website.
