DuPage County is the tax-rate winner in the Chicago market — effective rates of 1.8–2.2% are the lowest of any collar county. The catch: DuPage home prices reflect that advantage. Communities in Naperville, Downers Grove, and Oak Brook command premiums that often exceed the 10-year tax savings. The buyer calculus depends entirely on how much more expensive DuPage homes are relative to the Kane or Will County alternatives you are comparing.
