Riley Township 2024 Equalization
The 2024 Riley Township Equalization Factor is 1.1222. This was determined by the Illinois Department of Revenue in a three-year sales ratio study which analyzes the arms’ length sales that have occurred in 2021, 2022, and 2023 and compares them to the prior year’s assessment values. The sales ratio study is done by the Illinois Department of Revenue for every county and township in the State of Illinois annually. The most recent data has determined that the 2024 assessments, in Riley Township as whole, must be increase by 1.1222 over the 2023 assessment levels.
The 2024 equalization factor of 1.1222 DOES NOT mean that house values have increased. This is a method used in order to assess the township as a whole at the statutory 33.33% of fair cash value. This allows you to check your final assessment for the year by keeping a correlation to market values since market values have increased significantly recently.
THIS EQUALIZATION FACTOR DOES NOT MEAN YOUR TAX BILL WILL INCREASE BY 1.1222.
If recent sales in your subdivision and neighborhood indicate that your parcel is overvalued after the application of the 2024 equalization factor, then that is a basis for an assessment appeal. Additionally, if your property or home is over-assessed compared to other similar properties or homes in your subdivision or neighborhood, this would also be a legitimate basis for an appeal. Property owners will not be able to appeal an assessment value based solely on the 1.1222 equalization factor.
