Property Tax Bills Across Farmington, Fulton County, Illinois

In Farmington, the median home price is $90,556, and the median property tax bill is $2,358.00, which is slightly below the national median property tax bill of $2,400. Tax bills can vary widely, with the 25th percentile at $1,466, the 75th percentile at $3,341, and the 90th percentile at $4,621.
