The Cook County Assessor’s Office has announced that it will be accepting appeals of the assessed valuations of Oak Park properties between April 8 and May 20. During the appeal period, the Oak Park Township Assessor’s Office will be available to help taxpayers who wish to appeal their 2025 assessed values.
Taxpayers should note that Oak Park’s 2025 assessed values do not reflect a reassessment. All Oak Park properties were reassessed in 2023, and most of the values set that year will remain in effect until Oak Park’s next reassessment in 2026. Some taxpayers assume that valuation appeals can only be filed in reassessment years, but in fact, appeals can be filed every year. Successful appeals filed in 2025 will impact tax bills in the summer or fall of 2026.
Individuals who would like help filing appeals should contact the Township Assessor’s Office at 708-383-8005 to set up appointments during the appeal period.
