How to appeal a Tazewell County property tax assessment

HomeTaxChallenge has not verified the Tazewell County 2026 Board of Review filing window. 2026 deadline: TBD. Check with your assessor (Tazewell County Supervisor of Assessments) or the Tazewell County Board of Review for the current deadline before filing. Illinois appeals are filed with the county Board of Review; the next level is the Property Tax Appeal Board (PTAB).

Steps

1. Look up your Tazewell County parcel to confirm the PIN, township and current assessment.
2. Confirm the 2026 filing deadline and complaint form directly with the Tazewell County Board of Review.
3. Choose a basis: overvaluation (recent comparable sales) or equity (similar assessed values). Non-farm residential property in Illinois is generally assessed at one-third of fair cash value.
4. File the complaint and evidence with the Board of Review before the deadline. The next level is the Illinois Property Tax Appeal Board (PTAB).
