COVID-19 Update

Per Executive Order 2020-3, issued by President Preckwinkle, to protect the health and safety of our staff and customers, and to help mitigate the impact of COVID-19, essential functions of government will continue while protecting the public and our workforce through a reduction of the footprint in the County Building. 

Starting March 18, 2020 and until further notice, we will be temporarily closed to the public.  To make any tax, fine or fee payments, please pay online (where available) or by US Mail.  In person payments will not be available during this time.  We will continue to service our taxpayers, but with limited availability. If you have any further questions, please call us at (312) 603-6961 (limited staff) and/or please email ccdor@cookcountyil.gov or revenuecompliance@cookcountyil.gov.  Staff will be working to respond to all email inquiries.  

The business community and residents of Cook County are facing many challenges due to the COVID-19 outbreak.  In an effort to alleviate some of the financial burden at this time of great uncertainty, the Department of Revenue is providing taxpayer relief in multiple areas.

Monthly Due Dates Extended

To assist taxpayers during this difficult time,  the due dates for the February 2020 , March 2020 and April 2020 filing periods for our monthly Home Rule taxes have been extended. Returns and payments for February 2020 , March 2020 and April 2020 are now due on or before June 1, 2020.  Interest and penalties will also not be assessed on these periods until after June 1, 2020.

The extended due dates apply to monthly filings/payments of the following Home Rule taxes that are currently available on our taxpayer portal: Alcoholic Beverage Tax, Amusement Tax, Gasoline and Diesel Fuel Tax, Hotel Accommodations Tax and Parking Lot and Garage Operations Tax.  The extended due dates also apply to monthly filings/payments for the following Home Rule taxes that are NOT available on our taxpayer portal: Firearm and Firearm Ammunition Tax, New Motor Vehicle Tax, Tobacco Tax and Use Tax. 

Programming changes are necessary for us to extend the due dates in our Integrated Tax Processing System.  Until that is completed, when making a payment through the online portal, the system may indicate you owe interest and/or penalties.  Simply pay the tax amount only by June 1, and within 48 hours the system will update to remove any interest and/or penalties for the February 2020 , March 2020 and April 2020 tax periods.

If you have specific questions regarding the taxpayer relief package, submit a general inquiry service request through the Taxpayer Portal or email us at revenuecompliance@cookcountyil.gov.

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.
