Civic Federation Property Tax Primers
The Cook County property tax system is highly complex and often difficult for the public to understand. To improve transparency and promote accountability, the Civic Federation is updating its series of primers that explain the key processes and government entities involved in the property tax system. These primers were originally created between 2009 and 2011 and are available here.
