A city may levy a general business occupation tax upon the businesses and users of space within an enhanced employment area for the purpose of paying all or any part of the costs and expenses of any redevelopment project within such enhanced employment area. After March 27, 2014, any occupation tax imposed pursuant to this section shall make a reasonable classification of businesses, users of space, or kinds of transactions for purposes of imposing such tax, except that no occupation tax shall be imposed on any transaction which is subject to tax under section 53-160, 66-489, 66-489.02, 66-4,140, 66-4,145, 66-4,146, 77-2602, or 77-4008 or which is exempt from tax under section 77-2704.24. The collection of a tax imposed pursuant to this section shall be made and enforced in such a manner as the governing body shall by ordinance determine to produce the required revenue. The governing body may provide that failure to pay the tax imposed pursuant to this section shall constitute a violation of the ordinance and subject the violator to a fine or other punishment as provided by ordinance. Any such occupation tax agreed to by the authority and the city shall remain in effect so long as the authority has bonds outstanding which have been issued stating such occupation tax as an available source for payment.
