(65 ILCS 110/50)
    Sec. 50. Special tax allocation fund.
    (a) If a county clerk has certified the "total initial equalized assessed value" of the taxable real property within an economic development project area in the manner provided in Section 45, each year after the date of the certification by the county clerk of the "total initial equalized assessed value", until economic development project costs and all municipal obligations financing economic development project costs have been paid, the ad valorem taxes, if any, arising from the levies upon the taxable real property in the economic development project area by taxing districts and tax rates determined in the manner provided in subsection (b) of Section 45 shall be divided as follows:
        (1) That portion of the taxes levied upon each
    
taxable lot, block, tract, or parcel of real property that is attributable to the lower of the current equalized assessed value or the initial equalized assessed value of each taxable lot, block, tract, or parcel of real property existing at the time tax increment financing was adopted shall be allocated to (and when collected shall be paid by the county collector to) the respective affected taxing districts in the manner required by law in the absence of the adoption of tax increment allocation financing.
        (2) That portion, if any, of the taxes that is
    
attributable to the increase in the current equalized assessed valuation of each taxable lot, block, tract, or parcel of real property in the economic development project area, over and above the initial equalized assessed value of each property existing at the time tax increment financing was adopted, shall be allocated to (and when collected shall be paid to) the municipal treasurer, who shall deposit the taxes into a special fund (called the special tax allocation fund of the municipality) for the purpose of paying economic development project costs and obligations incurred in the payment of those costs.
    (b) The municipality, by an ordinance adopting tax increment allocation financing, may pledge the monies in and to be deposited into the special tax allocation fund for the payment of obligations issued under this Act and for the payment of economic development project costs. No part of the current equalized assessed valuation of each property in the economic development project area attributable to any increase above the total initial equalized assessed value of those properties shall be used in calculating the general State aid formula under Section 18-8 of the School Code or the evidence-based funding formula under Section 18-8.15 of the School Code, until all economic development projects costs have been paid as provided for in this Section.
    (c) When the economic development projects costs, including without limitation all municipal obligations financing economic development project costs incurred under this Act, have been paid, all surplus monies then remaining in the special tax allocation fund shall be distributed by being paid by the municipal treasurer to the county collector, who shall immediately pay the monies to the taxing districts having taxable property in the economic development project area in the same manner and proportion as the most recent distribution by the county collector to those taxing districts of real property taxes from real property in the economic development project area.
    (d) Upon the payment of all economic development project costs, retirement of obligations, and distribution of any excess monies under this Section and not later than 23 years from the date of the adoption of the ordinance establishing the economic development project area, the municipality shall adopt an ordinance dissolving the special tax allocation fund for the economic development project area and terminating the designation of the economic development project area as an economic development project area. Thereafter, the rates of the taxing districts shall be extended and taxes shall be levied, collected, and distributed in the manner applicable in the absence of the adoption of tax increment allocation financing.
    (e) Nothing in this Section shall be construed as relieving property in the economic development project areas from being assessed as provided in the Property Tax Code or as relieving owners or lessees of that property from paying a uniform rate of taxes as required by Section 4 of Article IX of the Illinois Constitution.
