Real Estate And Tax Services

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 years (currently defined as tax year 2006 and earlier) 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.
