(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 Director of Finance under this article it may be refunded as provided in this section. Except as otherwise provided in this section, refunds of overpaid taxes shall be made in the same manner as provided in Sec. 21.07 of this chapter for refunds of overpayments in Business Taxes.
(b) A person required to collect and remit taxes imposed under this article may claim a refund or take as credit against taxes collected and remitted the amount overpaid, paid more than once or erroneously or illegally collected or received when it is established in a manner prescribed by the Director of Finance that the tenant 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 so collected has either been refunded to the tenant or credited to charges subsequently payable by the tenant to the person required to collect and remit.
(c) No refund shall be paid under the provisions of this section unless the claimant establishes their right thereto by written records showing entitlement thereto.
