Cook County 2021 First Installment Tax Bills
Pin It

The Cook County Treasurer will be mailing 2021 1st installment property tax bills soon and payment will be due March 1, 2022. 

1st installment bills are 55% of last year's total tax and must be paid regardless of whether or not you have a tax appeal pending.

Any changes to your assessment through a tax appeal will be reflected in the 2nd installment bill that will be mailed later in the year.
