Property tax bills in Iroquois County are based on a home’s assessed value, local tax rates, and any exemptions a homeowner may qualify for. When a property’s market value changes, the assessed value can change too, which can raise or lower the tax bill. Local taxing bodies then apply their rates to that assessed value to determine what each homeowner owes.

For homeowners, this means the final bill can vary widely even among similar homes. In Iroquois County, the median home price is $113,187, while tax bills range from $1,976 at the 25th percentile to $5,868 at the 75th percentile, with the 90th percentile reaching $8,661.
