S.D. Codified Laws § 36-33-52
The board may place a license on inactive status at the request of a licensee and the payment of a fee prescribed by the board. An inactive license expires four years after the date of issuance. An inactive license may be reactivated by payment of the license renewal fee and proof of having completed at least forty hours of continuing education during the two-year period immediately preceding the reactivation request. If a license is not reactivated before its expiration, all provisions applicable to an applicant for licensure also apply in order for the license to be restored to active status.
Any license that is on inactive status as of July 1, 2020, expires on November 30, 2022, unless the licensee meets the requirements for reactivation before that time.
