Cook County Property Taxes
Property taxes in Cook County are proportional to assessed property values. Therefore, a higher assessed property value means a higher tax bill. In an effort to estimate fair market prices, the Assessor re-estimates a property's value once every 3 years (each year 1/3 of Cook County properties are reassessed).
By law, the assessed value of every property in Cook County may be appealed each year even though the Assessor re-values only 1/3 of them.
If a property's assessed value is successfully appealed during a reassessment year, this means that the property owner will save money for 3 straight years.
Cook County has 38 townships. Property taxes can be appealed only during specific times:
