Pappas makes it easier than ever to prepay next year’s taxes

Beginning Tuesday, December 12, 2017, Cook County Treasurer Maria Pappas is accepting online prepayments of next year’s First Installment property tax bill.

For taxpayers who prefer to pay by mail or in person, Pappas will also enable taxpayers to download and print a prepayment bill themselves.

The improvements are being made as the number of prepayment requests surges this year.

Under state law, Tax Year 2017 First Installment taxes, due March 1, 2018, are 55 percent of the prior year's total tax. To prepay, taxpayers must have their 14-digit Property Index Number (PIN), which can be found at the top of the most recent tax bill, near the amount due. Taxpayers can also use their property address to look up their PIN on

Here’s how to prepay:

  • Online—Go to and select “Prepay Your 2017 Taxes.” You can use your bank account or credit card to pay
  • Download your bill—You can print a copy of your prepayment bill by choosing “Download Your Bill” on the homepage and entering your PIN or property address
  • By mail—Send the prepayment bill and your payment to:
    Cook County Treasurer
    PO Box 805436
    Chicago, IL 60680-4115
  • In person—Submit the prepayment bill and payment at a Chase branch bank or the Treasurer’s Office, 118 N. Clark St., Room 112, Chicago
