Prepayment of First Installment Cook County Property Taxes

Posted: 12/18/2017

Some taxpayers choose to prepay the First Installment tax for reasons such as winter travel or to increase their tax write-offs for the current year. Cook County taxpayers may choose to participate in the optional program of prepaying their First Installment taxes. The First Installment is an estimated bill equal to 55% of the prior year's total tax.
