Cook County and Property Taxes: City of Chicago

Cook County and Property Taxes

All properties in Cook County are reassessed on a triennial schedule. Every three years, the new valuations – along with appeals, exemptions, local tax levies, and assessments of nearby properties – determine the amount of future property tax bills.

The Assessor’s Office, the Board of Review, the Cook County Clerk, and the Cook County Treasurer all play a role in the property tax system.

In addition to setting property values, the Assessor’s Office collaborates with other government agencies to stimulate economic growth, develop tax relief proposals, increase the amount of affordable housing in the county, and make the tax system more equitable.

Cook County Townships

For the purposes of reassessment scheduling, the 30 townships within Cook County are divided into three groups: north/northwest suburbs, south/southwest suburbs, and the City of Chicago.

Each township’s government provides a set of core services to its residents. These usually include road maintenance, issuance of building permits, and processing of tax exemption applications. All of these functions are financed by property tax revenue.

Some township governments offer community mental health services and social programs. They also maintain recreational areas and perform other functions beyond the core services. Property tax revenue is a source of funding for these local programs and services as well.  

Taxpayers can access statistics about their township via the Cook County Assessor’s Office website, including median sales ranges for different property classes of residential real estate.

City of Chicago

The townships of Hyde Park, Jefferson, Lake, Lakeview, North Chicago, Rogers Park, West Chicago, and South Chicago all fall into the City of Chicago grouping.

They were reassessed in 2015 and 2018. They will be reassessed again in 2021.
