About

OverTaxed IL analyzes public Cook County records and prepares a defined Assessor-stage appeal packet. You review it, sign it, and file it yourself. OverTaxed IL is not a law firm and does not provide legal or tax advice. We do not guarantee a reduction. County decisions are final, and a change in assessed value does not produce an equal change in a tax bill.
