The due date for Tax Year 2022 First Installment property taxes this year is April 3. Nearly 1.8 million tax bills will arrive in mailboxes by early March. They are currently available online at cookcountytreasurer.com.
Typically, First Installment property tax bills are due on March 1. But state lawmakers extended the due date because Second Installment bills were late last year.
