The Cook County Treasurer has released the first installment of 2017 property tax bills with a due date of March 1, 2018. This is an estimated tax bill; the amount due will be 55% of the prior year’s total tax. If you have a 2017 appeal pending you still need to pay this bill. Any change in the 2017 tax bill will be reflected on the second installment tax bill later this summer.

If you have a new Property Tax Index Number for 2017, your first installment tax bill will be zero. The entire tax bill for 2017 will be reflected and due on the second installment.
