In addition to the taxes now or hereafter provided by law, there is hereby levied upon, assessed to and shall be collected from all telephone or communication utilities as defined by Section 77-3-1, Mississippi Code of 1972 and regulated under said Section 77-3-1, an additional tax of two per cent of the gross amount of revenue made and collected on local business from customers within the corporate limits of any municipality of the State of Mississippi, which qualifies as provided by the City Utility Tax Law. Such public utility shall add to the sales price of its service the amount of any tax due under the provisions of the City Utility Tax Law to the extent that such tax was not included as a part of the cost of furnishing services in the fixing of the rates and charges for such service by the Mississippi Public Service Commission. The tax levied herein shall not apply to the cash receipts collected through coin boxes or other mechanical devices where it is impracticable to render periodic statements and thereby add the tax to the sales price of its service.

Any such public utility which pays any municipality of the State of Mississippi the compensation provided for in municipal franchises or levied and provided for by Section 77-3-17, Mississippi Code of 1972, shall be exempt from the tax herein imposed and from the provisions of the City Utility Tax Law. In addition, any such public utility which makes payment of the tax imposed herein shall not be required to make payments, if any, which may be required under the terms of said Section 77-3-17.
