3.26.140 REFUNDS.
   A.   Whenever the amount of any tax has been overpaid or paid more than once, or has been erroneously or illegally collected or received by the tax administrator under this chapter, it may be refunded as provided in this section.
   B.   Notwithstanding the provisions of subsection A of this section, a service supplier may claim a refund, or take as credit against taxes remitted the amount overpaid, paid more than once, or erroneously or illegally collected or received when it is established that the service user from whom the tax has been collected did not owe the tax; provided, however, that neither a refund nor a credit shall be allowed unless the amount of the tax erroneously or illegally collected has either been refunded to the service user or credited to charges subsequently payable by the service user to the person required to collect and remit. A service supplier that has collected any amount of tax in excess of the amount of tax imposed by this chapter and actually due from a service user, may refund such amount to the service user and claim credit for such overpayment against the amount of tax which is due upon any other monthly returns, provided such credit is claimed in a return dated no later than three years from the date of overpayment.
   C.   Notwithstanding other provisions of this section, whenever a service supplier, pursuant to an order of the California Public Utilities Commission or a court of competent jurisdiction makes a refund to service users of charges for past utility services, the taxes paid pursuant to this chapter on the amount of such refunded charges shall also be refunded to service users, and the service supplier shall be entitled to claim a credit for such refunded taxes against the amount of tax which is due upon the next monthly returns. In the event this chapter is repealed, the amounts of any refundable taxes will be borne by the city.
   D.   A service supplier may refund the taxes collected to the service user in accordance with this section or by the service supplier's customary practice. (Ord. 98-104, Exh. A § 2(part), 1998).
