Property Tax Cycle
The new year introduces the start of a new property tax cycle. The timing of things this year will be slightly different, however, we will continue to have appeal sessions with the Cook County Assessor and the Board of Review. Exemption applications will be processed, tax levies will be determined by taxing bodies and property tax bills calculated, sent and due all before the end of the year.
