The system for appealing property assessments in Illinois is a multi-level system that affords several opportunities for taxpayers to have incorrect or inaccurate assessments corrected. Those levels include the Township Assessor level, the County Board of Review level, the Illinois Property Tax Appeal Board level, and if the owners are still not satisfied after exhausting these administrative remedies they can take their appeal to court.
If a property owner thinks their assessment is incorrect, the township assessor should be the first person contacted. An assessor who still has the assessment books for a given year can correct any assessment. Calling an erroneous assessment to the assessor's attention early in the year may result in a correction without using the formal appeal process. Property owners should contact their township assessor for information.
If the property owner still thinks their assessment is incorrect they are entitled to proceed with a formal appeal to the county Board of Review if the deadline for filing a complaint has not passed.
Timing of appeals
The statutory time for filing appeals (complaints) with the county Board of Review is 30 days after the assessments are published. 2019 Assessments were published on Auguest 14th & 15th and the deadline for filing a complaint was September 16th, 2019.
Appeals to the Illinois Property Tax Appeal Board
If the property owner is dissatisfied with the Board of Review's decision, the owner can appeal the assessment to the State Property Tax Appeal Board (PTAB). Forms for filing that appeal are available in the Supervisor of Assessments and Board of Review Offices. Appeals to the PTAB must be postmarked within 30 days of the date of Board of Review's decision. PTAB hearings are held in Rockford and the property owner is not required to hire an attorney.
