Treasurer’s Office

The Cook County Treasurer’s Office has the primary goals of mailing, collecting, investing, and distributing all real estate taxes for the county of cook. The Treasurer’s Office prints and mails the real estate tax bills to the taxpayers of record. We place the mailing name and address to a tax bill based on the information provided by the taxpayer. There are 1.6 million taxable parcels, with an annual collection of over $9 billion dollars. Real estate taxes are billed twice per year; 1st installment due the first business day in March; 2nd installment due late summer. The duties surrounding the collection include:

  • refunding of duplicate or overpayments
  • certificate of error refunds
  • specific objection refunds
  • transferring taxes to appropriate real estate permanent index numbers
  • annual and scavenger tax sales for delinquent properties
  • processing court orders involving unique cases of tax payments or sales
  • the accounting and auditing of collections and distributions

The Treasurer’s Office is also the banker for the County of Cook, keeping the records and approving the investments for many of the accounts needed in general Cook County operations.
