First Installment of 2023 property tax bills sent to homeowners

Cook County Treasurer Maria Pappas has mailed 1.8 million first installments of property taxes for tax year 2023. Payments are due March 1, 2024.

The first installment is 55% of the previous year’s total tax. Exemptions that can reduce a property owner’s taxes are applied to the second installment bill.

To make a payment online, visit and follow these steps:

  • Select the blue box labeled “Pay Online for Free”

A picture of your property should appear so you’ll know you’re paying the correct bill. There is no fee to pay online from your bank account. The Treasurer’s Office accepts partial payments but first installment taxes must be paid by March 1 to avoid a late charge of 0.75% per month, as mandated by Illinois law.
