The court which orders a sale in error shall order the refund of all other taxes paid by the owner of the certificate of purchase or his or her assignor which were validly posted to the tax judgment, sale redemption and forfeiture record subsequent to the tax sale, together with interest on the other taxes under the same terms as interest is otherwise payable under Section 260. The interest under this Section shall be calculated at the rate of 1% per month from the date the other taxes were paid and not from the date of sale. The collector shall take credit in settlement of his or her accounts for the refund of the other taxes as in other cases of sale in error under Section 255.
