Property Tax Appeal Board

Visit ASI to view the status
of your appeals.

The Property Tax Appeal Board (PTAB or Board) is a quasi-judicial body providing taxpayers and taxing districts an unbiased forum to contest a property's assessment. The Board consists of five Board Members appointed by the Governor, with the advice and consent of the Senate, and a professional staff that aids the Board in its mission. The Board's jurisdiction is limited to only adjudicating the correct assessment of a property based on equity and the weight of the evidence. The Board does not have jurisdiction to review the amount of a tax bill, or the tax rate used in the tax bill's computation. Likewise, the Board has no authority to exempt property from taxation.

Effective July 1, 2023, all appeals, regardless of county, filed by an attorney-represented appellant must be filed through the eFiling Portal.
