Township Assessor: January 1st of each year your property is assessed by the Township Assessor.
Supervisor of Assessments: Mid to late summer, the Assessor completes his or her valuation and turns the assessment roll over to the Supervisor of Assessments. The Supervisor of Assessments applies an Equalization Factor on a Township basis to bring the level of assessments to the State required 33.33% (one-third) of market value.
Assessment Change Notices Mailed & Published: Late summer to early fall, written notice of the Assessor's changes are mailed to the property owners as well as publishing in the local newspapers a list of all parcels where values changed from the previous year. NOTE: 2007 (and every four years before and after) is a General Assessment Year. Every property owner during a General Assessment Year receives an Assessment Notice. All other years, a property owner is noticed only if the Assessor made a change that affects the property’s value.
Filing a Complaint: Within 30 days of the above publication & notice, assessment complaints may be filed with the Board of Review.
Board of Review: Mid fall to early winter, hearings are held by the Board of Review to hear complaints filed. The Board of Review also revises the assessment roll as necessary.
State of Illinois Property Tax Appeal Board: After written notice of the Board of Review decision, the taxpayer may within 30 days file an appeal with the State of Illinois Property Tax Appeal Board.
County Clerk: Late winter to early spring, the Board of Review turns the revised assessment roll over to the County Clerk, where tax rates are determined and the roll is certified.
County Treasurer: After certification, the County Clerk turns the assessment roll over to the County Treasurer. Tax bills are prepared for mailing by the County Treasurer. The bills are usually mailed in May and due in two equal payments in June and September. Therefore, as an example, an assessment placed on your property as of January 1 this year, causes a tax bill to be issued in May of next year.
