Property Tax Appeal Board

eFiling is now available for all residential appeals in all 102 counties in Illinois. It is recommended that pro se appellants (individuals filing an appeal without an attorney) review the Before You File Your Appeal With PTAB and Checklist pages of this website before they start the eFiling process. Use of the eFiling system for appeals filed by attorneys will be mandatory under PTAB's rules.

The Property Tax Appeal Board (PTAB or Board) is a quasi-judicial body made up of five Board Members appointed by the Governor, with the advice and consent of the Senate, and a professional staff to aid the Board. The PTAB was created in 1967 to provide an unbiased forum for taxpayers and taxing bodies outside of Cook County that are dissatisfied with property assessments. In 1997, the PTAB's jurisdiction was expanded to include all Counties in Illinois. The Board primarily considers appeals after decisions from County Boards of Review. The burden of proof before the Board is "a preponderance of the evidence" when market value is the basis of the appeal or "clear and convincing evidence" when unequal treatment in the assessment process is the basis of the appeal. The Board will only determine the correct assessment of property on appeal based on equity and the weight of the evidence. The amount of the tax bill or the tax rate used in the computation is determined by local county officials and may not be appealed to the Board. Likewise, the Board has no jurisdiction to exempt property from taxation.
