S.D. Codified Laws § 10-46-15
The gross receipts from sales of tangible personal property, any product transferred electronically, and the gross receipts from sales, furnishing or service of electrical energy, natural and artificial gas, water and communication service to and for use by religious educational institutions and private educational institutions currently recognized as exempt under section 501(c)(3) of the Internal Revenue Code as in effect on January 1, 1983, and nonprofit, charitable hospitals when purchases are made by authorized officials, payment made from the institution's funds and title to the property retained in the name of the institutions, are specifically exempted from the tax imposed by this chapter. For the purposes of this section, a private educational institution shall be defined as an institution currently recognized as exempt under section 501(c)(3) of the Internal Revenue Code as in effect on January 1, 1995, maintaining a campus physically located within this state; and accredited by the South Dakota Department of Education or the North Central Association of Colleges and Schools.
This exemption does not extend to sales to or purchases of tangible personal property or any product transferred electronically for the personal use of officials, members, or employees of such institutions or to sales to or purchases of tangible personal property or any product transferred electronically used in the operation of a taxable retail business. The exemption provided in this section does not, in any manner, relieve the institution from the payment of the additional and further license fee imposed on the registration of motor vehicles. All institutions claiming this exemption shall, at the end of each quarter of each calendar year, file with the Department of Revenue a list of all purchases on which exemption was claimed, fully itemized, showing name and address of vendors, description of property purchased, purchase price, and brief explanation of use or intended use.
