In counties with 3,000,000 or more inhabitants, the county clerk shall, and in all other counties the county clerk may, extend on each valuation of property the sum of the taxes to be extended upon the property in one total. When collected, the taxes shall be divided among the taxing bodies levying the same in proportion to the rates as determined by the clerk, after deducting from any tax the amount or amounts, if any, ruled invalid by the final judgment of a court of competent jurisdiction, and in the event a municipality has adopted tax increment financing under Division 74.4 of Article 11 of the Illinois Municipal Code, after deducting from any tax, except from a tax levied by a township to retire bonds issued to satisfy court-ordered damages, the amount to be placed in the special tax allocation fund, and distributing the amount to be placed in the special fund to the municipal treasurer under Section 11-74.4-8 of that Act. The clerk shall certify in the collector's books the rates as determined for extension in such manner as to indicate the different taxes entering into each total. All officers dealing with such extensions, shall record them by totals. The clerk shall show in the collector's books the total tax due each taxing body as extended.
If (i) a county clerk does not extend in one total on each valuation of property the sum of the taxes to be extended upon the property and (ii) a municipality has adopted tax increment financing under Division 74.4 of Article 11 of the Illinois Municipal Code, then the clerk may not deduct the amount to be placed in the special tax allocation fund from a tax levied by a township to retire bonds issued to satisfy court-ordered damages.
