Every year, homeowners may appeal their property tax assessment twice - first with the Cook County Assessor's Office and second with the Cook County Board of Review. Your property tax assessment, or property value, is the first factor used to calculate your property tax bill. Homeowners have the opportunity to appeal their property tax assessment to ensure it is fair and accurate.

The most common reasons to appeal include:

  • Lack of Uniformity: the assessed value of your property is not in line with other similar properties in your neighborhood.
  • Over-Valuation: the proposed assessed valuation of your property is higher than its actual price.
  • Property Description Error: this may be an error in the description of your property that adversely effects the assessed valuation or your property has been damaged by a fire, flood, or other casualty and/or part of all of the building has been demolished.

During scheduled office hours, my staff will be available to answer property tax questions and homeowners may file their appeal. Please bring your most recent property tax bill (the "yellow form") and any additional documents, such as a recent appraisal, that may be helpful for your appeal.

Property Tax Exemption forms

Applications for the Homeowner, Senior Citizen, Senior Freeze and Long-Time Occupant Exemptions are available by the Cook County Assessor's Office. All eligible exemptions you apply for will result in a deduction on your second-installment property tax bill to be issued by each year by the Cook County Treasurer's Office.

Friendly Reminders:

  • If you received the homeowner's exemption last year, the homeowner's exemption for this year will automatically be applied to your second installment property tax bill.
  • All eligible senior citizen homeowners must re-apply for their senior exemptions (Senior Citizen and Senior Freeze) every year.
  • Please include a photo copy of your Illinois-issued driver's license or Illinois-issued identification card with your completed exemption application when submitted to the Cook County Assessor's Office. 



In addition to above information, I have created the Citizens' Guide to Property Tax Bills, a step-by-step guide walks a homeowner through the process the County took to determine each property tax bill. I have also created a separate Citizens' Guide to Appealing Your Property Tax Assessment which explains how to appeal your property tax assessment with both the County Assessor's Office and the County Board of Review.
