Will County's effective property tax rate range of 2.0–2.5% is deceptively wide. Bolingbrook, on the DuPage border, runs closer to 2.0–2.2%. Communities near Joliet — Crest Hill, Romeoville — run 2.2–2.5%. Shorewood and Plainfield fall in the 2.2–2.4% range. The variation reflects different school district levies across the county's large geographic footprint. Using a single Will County rate for all purchase comparisons will produce the wrong number. Always pull the specific township and school district levy for the address you are evaluating.
