Cook County Treasurer Maria Pappas announced that property owners can now go to cookcountytreasurer.com to view, download and pay their Second Installment bill for the 2025 Tax Year. The Treasurer’s Office plans to mail 1.8 million bills to Cook County property owners on or before Sept. 1. Those 2025 second installment bills will be due a month later on Oct. 1. There’s no fee to pay by transferring funds directly from your bank account, and payments can be made 24 hours a day. Online payments are secure and eliminate the risk of a check being stolen from the mail. Property owners who wish to view, download, print out and electronically pay their bills should visit cookcountytreasurer.com.  Once there, select the blue box labeled “Pay Online for Free” and enter the address or Property Index Number (PIN). Credit card payments are also accepted online but carry a 2.08% convenience fee paid to the credit card company. Taxpayers can also pay at the Treasurer’s Office at 118 N. Clark St., Room 112, in downtown Chicago. Lastly, payments can be mailed to the Cook County Treasurer’s Office, with the taxpayer’s PIN, contact and property information included.  The canceled check serves as the receipt.
