McLean County deadline tracker

McLean County 2026 assessment appeal deadlines

In McLean County, you don't get one countywide deadline. Each township publishes its assessment list in a local newspaper, then you generally have about 30 days to file with the Board of Review. City limits are not township lines — check your parcel.

How to use this tracker Find your township → note its status → if open, run a free estimate; if TBD, get an alert; if closed, review next-step options.
Open — You can still file for 2026. TBD — The assessment list is not published yet. Closed — The 2026 Board of Review window ended.

Verified against McLean County sources: October 4, 2026. Statuses use America/Chicago time.
