SDCL § 10-12-1: Levy of state tax--Purposes covered by levy.

The state tax shall be levied by the Department of Revenue. The department shall determine the rate of state tax to be levied for the purposes prescribed by law and such rate shall be based on the aggregate value of the taxable property within the state as assessed and equalized by the department, and may not exceed a rate which will produce a revenue sufficient to defray the estimated expense of the current year and any deficiency that may remain unpaid of the expenses of the preceding year, together with a sufficient amount to pay the annual interest and provide a debt service fund for the payment of the public debt of the state, and for the payment of all appropriations made by the Legislature.
