S.D. Codified Laws § 3-13-94 (2026)
If, due to a payroll error, a participant's deferral is deposited in an investment alternative other than the one selected by the participant, the third-party administrator may correct the error by transferring the participant's deferral to the proper investment alternative, subject to any limitations that may be imposed by the vendor. No retroactive adjustment may be made.
