SDCL § 10-21-7.3: Determining delinquency of electronically transmitted payments.

Any property taxes remitted by electronic transmission pursuant to § 10-21-7.1 are delinquent if not remitted by the third day of the month following the month the taxes are due. However, notwithstanding the provisions of § 10-21-23, the first half of property taxes are not delinquent if the fifth payment made monthly pursuant to §§ 10-21-7.1 to 10-21-7.3, inclusive, is credited to the bank account designated by the treasurer on or before May first. If taxes become delinquent pursuant to this section, interest shall be added to the delinquent taxes at the Category G rate as established pursuant to § 54-3-16 for each day the taxes are delinquent.
