2023 2nd Installment Bills

For the first time in years, second installment property tax bills in Cook County are expected to be on time! Tax bills are expected to mail July 1^st with an August 1^st due date. Please plan accordingly as this may come as a surprise to some taxpayers who have come to expect due dates that have been considerably later than the August 1^st statutory deadline.



Second installment tax bills cannot be issued until the county’s two tax appeal agencies complete the processing of all Cook County tax appeals which happened on May 5^th. The Illinois Department of Revenue must then calculate the state equalizer, property tax exemptions are applied, and tax rates are set. Unless there are unexpected delays in the remaining steps in the process, this year’s bills should be due August 1^st.

2023 State Equalizer Cook County

The Illinois Department of Revenue announced the final Cook County property tax equalization factor on May 20^th. The department is required by law to calculate the factor to achieve uniform property assessment throughout the state.



This year, the multiplier increased from 2.9237 to 3.0163. The 3% increase reflects the three-year average level of assessments for Cook County property determined by Cook County Assessor Fritz Kaegi versus the actual selling price of individual properties.
