The State Department of Revenue shall charge the county, for collecting the taxes authorized to be levied herein, the costs of the department in collecting the taxes; provided such charge shall not, in any event, exceed five percent of the total amount of the taxes collected hereunder. Such charge for collecting the taxes for the county may be deducted each month from the tax proceeds collected before the amount of the proceeds due the county for that month is certified as provided in this section. The commissioner shall pay into the State Treasury all taxes collected under this subpart, as such taxes are received by the State Department of Revenue; and on or before the first day of each successive month (commencing with the month next succeeding the month in which the department makes the first collection of any of the taxes authorized to be levied hereunder) the commissioner shall certify to the Comptroller the amount of taxes collected under this subpart and paid by him or her into the State Treasury for the benefit of the county during the month immediately preceding the making of such certificate; provided, however, that before certifying the amount of the taxes paid into the State Treasury for the benefit of the county during each month, the commissioner may deduct from the taxes collected hereunder in the month the charges due the department for collection of the taxes. It shall be the duty of the Comptroller to issue his or her warrant each month, payable to the county, in an amount equal to the amount so certified by the commissioner as having been collected for the use of the county.
