Each Cook County township has two filing windows per year : one at the Cook County Assessor and a separate one at the Cook County Board of Review. Each window opens when that body announces it for your township and closes on the township-specific last filing date the body sets, typically about 30 days.
If both windows close before action is taken, all is not lost. Within 30 days of the postmark of a final Board of Review decision, a taxpayer may file at the Illinois Property Tax Appeal Board (PTAB), or, in the alternative, file a tax objection complaint in the Circuit Court of Cook County. PTAB and the Circuit Court are alternative remedies for the same tax year, not sequential.
File the initial appeal while your township’s window is open. The Assessor sets the closing date for each township; the window opens when reassessment notices are mailed. The Assessor stage is optional; a taxpayer may proceed directly to the Board of Review.
File during the Board’s session for your township. The Board is a quasi-judicial body that reviews the Assessor’s valuation based on the evidence the taxpayer submits. It does not perform an independent appraisal.
After a final Board of Review decision, the taxpayer may file at PTAB within 30 days of the postmark of the decision (35 ILCS 200/16-160), or, in the alternative, file a tax objection complaint in the Circuit Court of Cook County (35 ILCS 200/23-5 et seq.). The two routes are alternatives.
Statutory references: 35 ILCS 200/16-160 (PTAB filing window: 30 days from the postmark of the Board of Review’s final decision); 35 ILCS 200/23-5 through 23-25 (Circuit Court tax objection complaints). Specific township windows vary year to year and are set by the Cook County Assessor and the Cook County Board of Review.
