Property Tax Bills Across Marion County, Illinois

What a homeowner pays can vary widely across the county. The 25th percentile tax bill is $440, while the 75th percentile is $2,788 and the 90th percentile reaches $4,674. That spread shows how location, property characteristics, and local taxing authorities can create very different outcomes for similar homes.
