OTTAWA – LaSalle County has been issued a final property assessment equalization factor of 1.0000, the same as last year, according to David Harris, Director of the Illinois Department of Revenue. The property assessment equalization factor, often called the “multiplier”, is the method used to achieve uniform assessments among counties, as required by law. Under a law passed in 1975, property in Illinois should be assessed at one-third of its market value. Farm property is assessed differently, with farm homesites and dwellings subject to regular assessing, but with farmland assessed at one-third of its agriculture economic value.
Assessments in LaSalle County are at 33.09 percent of market value, based on sales of properties in 2019, 2020 and 2021.
