Cook County property owners who believe their property has been overvalued or improperly classified can appeal their property tax assessment to potentially lower their tax bill. Here is some information and resources related to appealing real estate taxes in Cook County:
- Real Property Income Expense (RPIE) Form: Owners of income-producing properties are required to submit a Real Property Income Expense (RPIE) form when filing an appeal for an income-producing property. The RPIE form helps owners report income, expense, and vacancy information about their buildings.
- Online Appeal Filing: Filing an appeal online ensures timely processing of appeals and ensures all accompanying documentation is easily accessible by analysts. Anyone filing an appeal on a property, either residential or commercial, on behalf of someone else must file the appeal online.
- Appeal Deadlines: Cook County has specific deadlines for filing property tax appeals. The window to appeal opens and closes at different times throughout the year depending on the township in which the property is located. The Cook County Treasurer’s website provides a listing of deadlines for appealing your property taxes in your township for both the Cook County Assessor and Board of Review.
- Cook County Property Info: The Cook County Property Info website provides detailed information about the property tax system in Cook County, including how the assessor assesses real estate, how appeals are accepted and decisions are reached, and how property tax rates are established.
- Hiring a Property Tax Firm: Property owners have the option to hire a property tax firm to file an appeal on their behalf for a fee or file themselves in person. ABC7 Chicago provides information on how to appeal Cook County property taxes and the three opportunities to file an appeal.
