If a county has adopted property tax allocation financing by ordinance for an economic development project area, the Department has approved and certified the economic development project area, and the county clerk has thereafter certified the "total initial equalized value" of the taxable real property within such economic development project area in the manner provided in subsection (b) of Section 6 of this Act, each year after the date of the certification by the county clerk of the "initial equalized assessed value" until economic development project costs and all county 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 6 of this Act shall be divided as follows:
The county, by an ordinance adopting property tax allocation financing, may pledge the funds in and to be deposited in 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 such properties shall be used in calculating the general State school aid formula, provided for in Section 18-8 of the School Code, or the evidence-based funding formula, provided for in Section 18-8.15 of the School Code, until such time as all economic development projects costs have been paid as provided for in this Section.
Whenever a county issues bonds for the purpose of financing economic development project costs, the county may provide by ordinance for the appointment of a trustee, which may be any trust company within the State, and for the establishment of the funds or accounts to be maintained by such trustee as the county shall deem necessary to provide for the security and payment of the bonds. If the county provides for the appointment of a trustee, the trustee shall be considered the assignee of any payments assigned by the county pursuant to the ordinance and this Section. Any amounts paid to the trustee as assignee shall be deposited in the funds or accounts established pursuant to the trust agreement, and shall be held by the trustee in trust for the benefit of the holders of the bonds, and the holders shall have a lien on and a security interest in those bonds or accounts so long as the bonds remain outstanding and unpaid. Upon retirement of the bonds, the trustee shall pay over any excess amounts held to the county for deposit in the special tax allocation fund.
When the economic development project costs, including without limitation all county obligations financing economic development project costs incurred under this Act, have been paid, all surplus funds then remaining in the special tax allocation funds shall be distributed by being paid by the county treasurer to the county collector, who shall immediately thereafter pay those funds 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.
Upon the payment of all economic development project costs, retirement of obligations and the distribution of any excess monies pursuant to this Section and not later than 23 years from the date of adoption of the ordinance adopting property tax allocation financing, the county 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; however, in relation to one or more contiguous parcels not exceeding a total area of 120 acres within which an electric generating facility is intended to be constructed, and with respect to which the owner of that proposed electric generating facility has entered into a redevelopment agreement with Grundy County on or before July 25, 2017, the ordinance of the county required in this paragraph shall not dissolve the special tax allocation fund for the existing economic development project area and shall only terminate the designation of the economic development project area as to those portions of the economic development project area excluding the area covered by the redevelopment agreement between the owner of the proposed electric generating facility and Grundy County; the county 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 with regard to the electric generating facility property not later than 35 years from the date of adoption of the ordinance adopting property tax allocation financing. Thereafter the rates of the taxing districts shall be extended and taxes levied, collected and distributed in the manner applicable in the absence of the adoption of property tax allocation financing.
Nothing in this Section shall be construed as relieving property in economic development project areas from being assessed as provided in the Property Tax Code or as relieving owners of that property from paying a uniform rate of taxes, as required by Section 4 of Article IX of the Illinois Constitution of 1970.
