Frequently asked questions
How is property tax calculated in DuPage County?
Your township assessor fixes an initial figure, which the county Supervisor of Assessments' office reviews for consistency, and local taxing bodies then bill their own rates against that value. Illinois's relatively high effective rates make the underlying figure especially consequential here.
How do I appeal my DuPage County assessment?
Your township assessor's office fields the first challenge; escalating to the county's Board of Review is the next move if that doesn't resolve things, backed by comparable sales as support.
Does DuPage County offer a homestead exemption?
Yes — Illinois runs several breaks for a primary residence, and further help exists for seniors and other qualifying owners, shrinking the figure your local rates apply to.
Is property tax higher in DuPage County than elsewhere?
DuPage generally tracks the statewide pattern of comparatively high effective rates rather than standing out on its own, high or low, within Illinois.
