35 ILCS 200/ Property Tax Code.

(35 ILCS 200/16-195)

Sec. 16-195. Review of decisions. Final administrative decisions of the Property Tax Appeal Board are subject to review under the provisions of the Administrative Review Law, except that in every case where a change in assessed valuation of $300,000 or more was sought, that review shall be afforded directly in the Appellate Court for the district in which the property involved in the Board's decision is situated, and not in the circuit court. The Property Tax Appeal Board shall certify the record of its proceedings only if the taxpayer or other entity seeking review under the Administrative Review Law pays to it for each page of legal size or smaller, the sum of 75¢ per page for testimony taken before the Board and 25¢ per page for all other matters contained in the record, and for any page larger than legal size the sum of $1, except that these charges may be waived when the Board is satisfied that the aggrieved party cannot afford to pay such charges. There shall be no charge to the taxpayer or other entity for certification by the Property Tax Appeal Board of any pages of the record which are furnished for inclusion in the record by the taxpayer or other entity seeking review. If payment for the record is not made by the taxpayer or other entity within 30 days after notice from the Board or the Attorney General of the cost thereof, the court in which the proceeding is pending, on motion of the Board, shall dismiss the complaint.

(35 ILCS 200/Art. 17 heading) Article 17. State Equalization Process

(35 ILCS 200/17-5)

Sec. 17-5. Equalization among counties. The Department shall act as an equalizing authority. It shall examine the abstracts of property assessed for taxation in the counties and in the assessment districts in counties having assessment districts, as returned by the county clerks, and shall equalize the assessments between counties as provided in this Code. Except as hereinafter provided, the Department shall lower or raise the total assessed value of property in each county as returned by the county clerk, other than property assessed under Sections 10-110 through 10-140 and 10-170 through 10-200, so that the property will be assessed at 33 1/3% of its fair cash value.

The Department shall annually determine the percentage relationship, for each county of the State, between the valuations at which locally-assessed property, other than property assessed under the Sections 10-110 through 10-140 and 10-170 through 10-200, as listed by assessors and revised by boards of review, and the estimated 33 1/3% of the fair cash value of the property. To make this analysis, the Department shall use property transfers, property appraisals, and other means as it deems proper and reasonable.

With the ratio determined for each county, the Department shall then determine the percentage to be added to or deducted from the aggregate reviewed assessment on property subject to local assessment jurisdiction, other than property assessed under the Sections cited above, to produce a ratio of assessed value to 33 1/3% of the fair cash value equivalent to 100%.

Sec. 17-10. Sales ratio studies. The Department shall monitor the quality of local assessments by designing, preparing and using ratio studies, and shall use the results as the basis for equalization decisions. In compiling sales ratio studies, the Department shall exclude from the reported sales price of any property any amounts included for personal property and, for sales occurring through December 31, 1999, shall exclude seller paid points. The Department shall not include in its sales ratio studies sales of property which have been platted and for which an increase in the assessed valuation is restricted by Section 10-30. The Department shall not include in its sales ratio studies the initial sale of residential property that has been converted to condominium property. The Department shall include compulsory sales occurring on or after January 1, 2011 in its sales ratio studies. The Department shall also consider whether the compulsory sale would otherwise be considered an arm's length transaction, based on existing sales ratio study standards.

When the declaration required under the Real Estate Transfer Tax Law contains financing information required under Section 31-25, the Department shall adjust sales prices to exclude seller-paid points and shall adjust sales prices to "cash value" when seller related financing is used that is different than the prevailing cost of cash. The prevailing cost of cash for sales occurring on or after January 1, 1992 shall be established as the monthly average 30-year fixed Primary Mortgage Market Survey rate for the North Central Region as published weekly by the Federal Home Loan Mortgage Corporation, as computed by the Department, or such other rate as determined by the Department. This rate shall be known as the survey rate. For sales occurring on or after January 1, 1992, through December 31, 1999, adjustments in the prevailing cost of cash shall be made only after the survey rate has been at or above 13% for 12 consecutive months and will continue until the survey rate has been below 13% for 12 consecutive months. For sales occurring on or after January 1, 2000, adjustments for seller paid points and adjustments in the prevailing cost of cash shall be made only after the survey rate has been at or above 13% for 12 consecutive months and will continue until the survey rate has been below 13% for 12 consecutive months. The Department shall make public its adjustment procedure upon request.

Sec. 17-15. Tentative equalization factor. The Department shall forward to the County Clerk of each county in each year its estimate of the percentage, established under Section 17-5, to be added to or deducted from the aggregate of the locally assessed property in that county, other than property assessed under Sections 10-110 through 10-140 and 10-170 through 10-200. The percentage relationship to be certified to each county by the Department as provided by Section 17-25 shall be determined by the ratio between the percentage estimate so made and forwarded, as provided by this Section, and the level of assessments of the assessed valuations as made by the assessors and thereafter finally revised by the board of review of that county. Such estimate shall be forwarded by the Department to the County Clerk of any County within 15 days after the chief county assessment officer files with the Department an abstract of the assessments of the locally assessed property in the county, as finally revised. The abstract shall be in substantially the same form as required of the County Clerk by Sections 9-250 and 9-255 after completion of the revisions thereafter to be made by the board of review of the county, except that the abstract shall specify separately the amount of omitted property, and the amount of improvements upon property assessed for the first time in that year. The chief county assessment officer shall forward the abstract to the Department within 30 days after returning the county assessment books to the county board of review.

Sec. 17-20. Hearing on tentative equalization factor. The Department shall, after publishing its tentative equalization factor and giving notice of hearing to the public in a newspaper of general circulation in the county, hold a hearing on its estimate not less than 10 days nor more than 30 days from the date of the publication. The notice shall state the provided hearing platform and accessibility instructions, date, and time of the hearing, the basis for the estimate of the Department, and further information as the Department may prescribe. The Department shall, after giving a hearing to all interested parties and opportunity for submitting testimony and evidence in support of or adverse to the estimate as the Department considers requisite, either confirm or revise the estimate so as to correctly represent the considered judgment of the Department respecting the estimated percentage to be added to or deducted from the aggregate assessment of all locally assessed property in the county except property assessed under Sections 10-110 through 10-140 or 10-170 through 10-200. Within 30 days after the conclusion of the hearing the Department shall mail to the County Clerk, by certified mail, its determination with respect to such estimated percentage to be added to or deducted from the aggregate assessment.
