OREGON – Ogle County’s final property assessment equalization factor for 2024 has been set at 1.0271, according to the Illinois Department of Revenue. The multiplier, used to ensure uniform property assessments across counties, helps prevent inconsistencies for taxpayers with similar properties in overlapping taxing districts.. This factor was determined after a public hearing and is based on property sales data from 2021 to 2023. While the multiplier effects assessment levels, it does not directly change total property tax bills, as tax rates are determined by local taxing bodies. Last year’s equalization factor for Ogle County was 1.0000.
