S.D. Codified Laws § 10-27-6
If the court finds that the party seeking relief was prevented from paying the tax because of lack of any original legal assessment, equalization, levy, or listing of the tax and that the party or the party's predecessors in interest in good faith failed or neglected to pay the tax on that account, the court may waive the requirement of deposit of interest. However, this provision does not relieve the county and taxing districts involved from payment of interest to the person who may originally have paid the tax or any part of the tax to or for them if the county has been made a party to the action. The court's order may direct the deposit to be made within such time as the court deems just but not less than ten days nor more than ninety days may be allowed for the deposit. Unless the party seeking such relief makes the deposit within such time as ordered, or stays the order by appeal to the Supreme Court, the action shall be dismissed upon the merits upon motion of any party to the action. If the party seeking relief makes the deposit as directed by the court, the action or proceeding shall then proceed to final determination, upon all issues involved. The making of the deposit is not an admission, estoppel, or other legal conclusion for or against any party. The making of the deposit may be considered only as a security for the purposes contemplated by this chapter.
