Assessor’s Office presents at Chi Hack Night: Why are property taxes in Chicago so high? (And what can be done to lower them)

The Cook County Assessor’s Office will join the Chicago civic tech community group Chi Hack Night to introduce a new tool called the Property Tax Simulator or PTAXSIM. PTAXSIM is a software code package implemented in the coding language R and designed to recalculate changes to Cook County property tax bills. It uses real assessment, exemption, TIF, and levy data to generate historic, line-by-line tax bills for any Cook County property from tax years 2006 to 2020 (for bills issued from 2007 through 2021).

Given some careful assumptions and data manipulation, PTAXSIM can provide hypothetical, but factually grounded, answers to counterfactual historical scenarios.

Join Dan Snow, Director of Data Science for a deep dive on Cook County’s property tax system. Using the new PTAXSIM tool, he’ll explore “what if” property tax scenarios and examine potential high-impact policy solutions to high property taxes.
