(35 ILCS 200/18-135)
Taxing district in 2 or more counties.
(a) Notwithstanding any other provisions to the contrary,
in counties which have an overlapping taxing district or districts that
extend into one or more other counties, the county clerk, upon receipt of
the assessments from the Board of Review or Board of Appeals, and of the
equalization factor from the Department, may use estimated valuations or
estimated rates, as provided in subsection (b) of this Section, for the
overlapping taxing district or districts if the county clerk in any other
county into which the overlapping taxing district or districts extend cannot
certify the actual valuations or rates for the district or districts.
(b) If the county clerk of a county which has an overlapping taxing district
which extends into another county has not received the certified valuations
or rates from the county clerk of any county into which such districts overlap,
he or she may subsequent to March 15, make written demand for actual or
estimated valuations or rates upon the county clerk of that county. Within 10
days of receiving a written demand, the county clerk receiving the demand shall
furnish certified or estimated valuations or rates for the overlapping taxing
district, as pertaining to his or her county, to the county clerk who made the
request. If no valuations or rates are received, the requesting county may
make the estimate.
(c) If the use of estimated valuations or rates results in over or under
extension for the overlapping taxing district in the county using estimated
valuations or rates, the county clerk shall make appropriate
adjustments in the subsequent year. Any adjustments necessitated by the
estimation procedure authorized by this Section shall be made by increasing
or decreasing the tax extension by fund for each taxing district where the
estimation procedures were used.
(d) For taxing districts subject to the Property Tax Extension Limitation Law, the adjustment for paragraph (c) shall be made after the limiting rate has been calculated using the aggregate extension base, as defined in Section 18-185, adjusted for the over or under extension due to the use of an estimated valuation by the county on the last preceding aggregate extension.
