About Us

The Cook County Clerk's office has a variety of property tax responsibilities. When delinquent or unpaid taxes are sold by the Cook County Treasurer's office, the Clerk's office handles the redemption process, which allows taxpayers to redeem, or pay, their taxes to remove the risk of losing their property. Records for delinquent taxes for prior tax years are the responsibility of the Clerk's office.

The Clerk's office also maintains the county's property tax maps and calculates tax rates based on the tax levies submitted by the county's taxing districts and the valuation of properties within those districts.
