The State Department of Revenue shall charge Cherokee County for collecting the sales tax levied under this subpart such amount or percentage of total collections as may be agreed upon by the Commissioner of Revenue and the Cherokee County Commission, but such charge shall not, in any event, exceed 10 percent of the total amount of the sales tax collected in the county under this subpart. Such charge for collecting such sales tax may be deducted each month from the gross revenues from such sales tax before certification of the amount of the proceeds thereof due Cherokee County for that month. The Commissioner of Revenue shall pay into the State Treasury all tax collected under this subpart, as such tax is received by the Department of Revenue, and on or before the first day of each successive month (commencing with the month following the month in which the department makes the first collection hereunder) the commissioner shall certify to the state Comptroller the amount of tax collected under the provisions of this subpart and paid by him or her into the State Treasury for the benefit of Cherokee County during the month immediately preceding such certification. Provided, however, that before certifying the amount of the tax paid into the State Treasury for the benefit of Cherokee County during each month, the commissioner may deduct from the tax collected in each month the charge due the department for the collection of the tax for the county. It shall be the duty of the Comptroller to issue his or her warrant each month payable to the county treasurer of Cherokee County in his or her official capacity in an amount equal to the amount so certified by the Commissioner of Revenue as having been collected for the use of the county. All revenues arising from the taxes herein authorized to be levied shall be distributed as follows: 40 percent to the county highway department fund for roads and bridges maintenance, construction, and repair; 20 percent to volunteer fire departments for fire protection to be divided equally among all certified volunteer fire departments that are active in the Cherokee County Volunteer Fire Department Association for a minimum of one year; 20 percent for the operation and maintenance of the Cherokee County jail system; and 20 percent to the county board of education to be used for educational purposes.
