Property Tax Bills Across Lake County, Illinois
Property tax bills in Lake County are based on the assessed value of a home, not its market price alone. Local taxing authorities set tax rates, and the final bill is calculated by applying those rates to the assessed value after any exemptions are considered. Because assessments can change as home values rise or fall, a homeowner’s tax bill can shift from year to year.
With a median home price of $317,980, Lake County homeowners often see bills that vary widely depending on neighborhood, school district, and local levies. The 25th percentile tax bill is $5,391, while the 75th percentile reaches $12,509. At the high end, the 90th percentile tax bill is $17,971.
These taxes can have a major impact on affordability, especially for owners whose homes are assessed above the county norm. In some areas, the median tax bill is much higher, with Bannockburn at $24,409, while Spring Grove is lower at $4,033.
