(A) If the sales and use tax is approved in the referendum, the tax is imposed on the first of May following the date of the referendum. If the reimposition of an existing sales and use tax imposed pursuant to this article is approved in the referendum, the new tax is imposed immediately following the termination of the earlier imposed tax. If the certification is not timely made to the Department of Revenue, the imposition is postponed for twelve months.
(B) The tax terminates on the earlier of:
(1) the final day of the maximum time period specified for the imposition; or
(2) the end of the calendar quarter during which the Department of Revenue receives a certificate under Section 4-10-360 indicating that no more bonds approved in the referendum remain outstanding that are payable from the sales tax and that all the amount of the costs of the projects approved in the referendum will have been paid upon application of the net proceeds during this quarter.
(C) Amounts collected in excess of the required net proceeds must first be applied, if necessary, to complete a project for which the tax was imposed; otherwise, the excess funds must be credited to the general fund of the governmental entities receiving the proceeds of the tax, in the proportion which they received the net proceeds of the tax while it was imposed.
