The Illinois Department of Revenue announces the final 2016
equalization factor of 2.8032 for Cook County. The department is required by law
to calculate the factor, also called the multiplier, to achieve uniform property
assessment throughout the state. The 2015 final equalization factor was 2.6685.
The department determines the final equalization factor for each county by
comparing the actual selling price of individual properties, over a three-year
period, with the assessed value placed on those properties by the county
assessor and adjusted by the board of review. If the median level of assessment
for all property in the county varies from the 33 1/3 percent level required by law,
an equalization factor is assigned to bring assessments to the legally mandated
level.
A tentative equalization factor of 2.7455 was issued on January 6, 2017.
The final factor is different than the tentative factor because of assessment
reductions by the Cook County Board of Review.
The three-year average level of assessments (weighted by class) for Cook
County property is 11.89 percent. The department calculated the multiplier to
bring the average level of assessments to the required 33 1/3 percent level by
dividing Cook County’s three-year average of 11.89 into 33.33.
