About the Department

The Department of Revenue collects and processes approximately $460,000,000.00 per year, and continues in its efforts to increase tax compliance and collections, along with providing efficient service to our customers through well-informed and skilled personnel.

The Department of Revenue was established by the Cook County Board of Commissioners in December 1992. The Department collects Cook County home rule taxes and other fees, and administers and enforces such collections. The Department audits and maintains delinquent property tax records. The Department of Revenue also researches and proposes new revenue sources for the County.

Like most other governmental bodies with revenue departments, the Cook County Department of Revenue centralizes collection and administration duties previously held by three other Cook County Offices (Auditor, Treasurer and Comptroller), making services and collections efficient and convenient for the public.

Taxes and a variety of fees collected by the Cook County Department of Revenue are alcoholic beverages, amusement, cigarette, gasoline and diesel fuel, new motor vehicle, parking, use and wheel taxes, cable television franchise fees, health insurance, lost ID fee, IBID payments and off-track betting fees, as well as fees for Building and Zoning, Environmental Control and Real Estate Management. Additionally, the Department collects licensing fees.
