How do I perform a property tax search in Cook County?
Search by your 14-digit PIN or your street address. The Cook County Assessor's website shows your assessed value, the details on record and your exemptions. The Treasurer's website shows your bills and what you have paid. The Cook County Property Tax Portal (cookcountypropertyinfo.com) shows the county offices' records in one place. This helps confirm your assessment and exemption eligibility.
