S.D. Codified Laws § 7-21-34
Whenever moneys shall have been actually provided for any funds of the county by a levy of taxes and such moneys shall not have been actually collected and covered into the county treasury but concerning the receipt of which moneys there can be no question, the board of county commissioners is authorized, by a unanimous vote, to anticipate the receipt of such moneys into such fund by drawing temporarily upon the moneys in any other fund of the county for which there shall not be immediate use.
Any fund temporarily depleted by virtue of the foregoing provision shall be fully restored within nine months after a draft upon the same for the benefit of another fund shall have been made, and the moneys coming into the latter fund shall first be used to restore such depletion. The board shall provide, at the time of making such withdrawal, for reimbursing the fund from which moneys are thus temporarily withdrawn.
