2021 to 2022 Assessment Change 19.8% increase

2021 to 2022 Levy request  7.3% increase

2022 Local Equalization Factor

For 2022 a local equalization factor of 17.4% was applied.  The mention of the local factor in the preamble when the assessments were published is required by 35 ILCS 200/9-213 and has been done and approved by the Department.

Why 17.4%?  Since Bond County was further into the 2022 assessment year, an analysis of the 2022 median level was also included in the applied local factor of 1.174.  The analysis of the 2022 median level indicated that the 2019, 2020, 2021 three year median level of 13.75% would not bring the median level into statutory compliance (33.33%) and in fact would fall short.  This would cause a positive state multiplier which would be added to tax bills.  A positive state multiplier does not increase the assessed value at the county level so the increase is not carried forward to the next year resulting in the next year being deficient, causing a positive state multiplier again.  The local factor does carry forward helping to end the need for a positive state multiplier.

Since the 1.174 local factor does affect the assessed values at the county level the tax rates for 2022 payable 2023 will likely decrease.  A positive state multiplier would not produce the same effect.
