Scope discipline

Cook County first.

This launch product is built around Cook County's township appeal windows, the Assessor's appeal process, and residential assessment methodology. We are not advertising an all-Illinois county packet until those workflows are separately verified.

Flat fee

The $69 packet is a preparation service. We prepare it; you review it, sign it, and file it with the county 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.
