S.D. Codified Laws § 13-37-16
For taxes payable in 2025, and each year thereafter, the school board shall levy no more than one dollar and forty-eight and eight-tenths cents per thousand dollars of taxable valuation, as a special levy in addition to all other levies authorized by law for the amount so determined to be necessary, and the levy must be spread against all of the taxable property of the district. The proceeds derived from the levy constitute a school district special education fund of the district for the payment of costs for the special education of all children in need of special education or special education and related services who reside within the district pursuant to the provisions of §§ 13-37-8.4 to 13-37-8.10, inclusive. The levy in this section is based on valuations where the median level of assessment represents eighty-five percent of market value as determined by the Department of Revenue. The total amount of taxes that would be generated at the levy pursuant to this section is considered local effort. Money in the special education fund may be expended for the purchase or lease of any assistive technology that is directly related to special education and specified in a student's individualized education plan. This section does not apply to real property improvements.
