Taxation and Finance Illinois 4 Minutes Read ยท published March 01, 2026 Flag of Illinois

In Peoria, Illinois, property owners who disagree with a valuation or a Notice of Assessment Change can seek review through local and state appeal channels. This guide explains how assessment notices work, where to look for official deadlines, and the typical appeal path from the Peoria County Assessor to the Peoria County Board of Review and, if needed, to the Illinois Property Tax Appeal Board. Read carefully to learn which office to contact, what documentation helps, and the practical next steps for filing an appeal or requesting a review.

How assessment notices and valuation work

The Peoria County Assessor prepares estimated market values and issues assessment notices when valuations change. The notice explains your new assessed value and gives information on how to protest or appeal at the county level. For local filing instructions and what your notice means, consult the Peoria County Assessor information page Peoria County Assessor[1].

Keep your assessment notice and all supporting records, like recent appraisals and sales data.

Penalties & Enforcement

Appealing an assessed value is distinct from paying property tax. Failure to pay property taxes can trigger statutory interest and tax sale procedures, but specific monetary fines or administrative penalties tied solely to filing or losing an assessment appeal are not specified on the cited county and state appeal pages referenced here. For enforcement of tax collection and the consequences of unpaid tax, contact the county treasurer or tax collector; for assessment disputes, the Board of Review and the Illinois Property Tax Appeal Board handle determinations of value and relief. See the Peoria County Board of Review for local procedures and the Illinois Property Tax Appeal Board for state-level appeals Peoria County Board of Review[2] and Illinois Property Tax Appeal Board[3].

Monetary penalties tied specifically to assessment appeals are not listed on the cited pages.
