S.D. Codified Laws § 10-46-22
The secretary of revenue may, upon application, authorize the collection of the tax imposed by this chapter by any retailer not maintaining a place of business within this state, who, to the satisfaction of the secretary of revenue furnishes adequate security to ensure collection and payment of the tax. The retailer shall be issued, without charge, a permit to collect the tax in such manner, and subject to such requirements as the secretary of revenue may prescribe by rule promulgated pursuant to chapter 1-26. If so authorized, the retailer shall collect the tax upon any tangible personal property or any product transferred electronically sold to the retailer's knowledge for use, storage, or other consumption within this state, in the same manner and subject to the same requirements as a retailer maintaining a place of business within this state. The authority and permit may be canceled if, at any time, the secretary of revenue considers the security inadequate, or that such tax can more effectively be collected from the person using the property in this state.
