2015 first Installment property tax payment information is now available at www.cookcountytreasurer.com!
In Cook County, the due date for the First Installment property taxes is always the first business day in March. A law passed by the Illinois Legislature in 2009 raises the First Installment tax from 50% to 55% of the prior year’s total tax. Please be prepared for this upcoming bill on March 2, 2015.
