Cook County’s Second Installment property tax bills for tax year 2015 are being mailed to nearly 1.8 million owners of homes, businesses and land with a due date of August 1, Cook County Treasurer Maria Pappas said today.

Pappas said owners of taxable property should pay before the due date to avoid interest of 1.5 percent per month for late payment. On-time payments can be made:

  • Online at
  • At some 400 Chase Bank locations in Illinois
  • From a checking or savings account at more than 200 participating community banks
  • By mail with a U.S. postmark no later than August 1, 2016

Second Installment bills include any property tax reassessments and exemptions calculated by the County Assessor and tax rates calculated by the County Clerk.
