Within 10 days after the meeting of the county commission at which such allowances were made, the presiding officer of the commission must certify to the Department of Revenue and the Comptroller separately the itemized list as ascertained and allowed by the commission of insolvent taxes, errors in assessments and taxes in litigation, showing in each instance the name of the taxpayer and the amount of state taxes and special taxes charged against him and, in the case of taxes in litigation, showing also when and in what court suit was brought; and if such lists are found to be correct and have been approved by the Department of Revenue, the Comptroller must, upon the final settlement of the collector, allow him credit for the amount of state taxes and special state taxes shown by such lists.
