Sec. 4. (1) The taxes imposed under this ordinance shall be billed by the public utility or resale customer as provided in section 3  1 herein, and they may imprint upon the face of the bill the amount of the tax and the name of the taxing city, commencing with the first regular billing period applicable to that person which starts on or after the date this ordinance is made operative for the taxing city, and shall be paid by the user along with the amounts billed for public utility services furnished.

(2) Any tax required to be paid by a user under this ordinance shall be deemed a debt owed by the user to the taxing city, and deemed delinquent from the time due until paid.

(3) Subject to extensions which may be granted for good cause shown, and to a utility collection fee of 1% of the tax amounts involved, all tax amounts under this ordinance billed by the public utility or resale customer in a given month shall be remitted to the taxing city on or before the last day of the following month, along with a return in such form as may be prescribed by the taxing city, showing such information as may be necessary for the proper administration of this ordinance provided that tax amounts based on billings shall be subject to adjustment for tax moneys not actually collected by the public utility or resale customer. Any such tax amounts not so remitted shall be deemed delinquent. An annual return for each year shall be filed by the public utility and resale customer on or before the end of the fourth month following the end of the tax year.
