Property Tax Appeal Board

Due to construction, PTAB's DesPlaines office is open to the public by appointment only. Call 847-294-4121 to make an appointment.

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.
