Cook County Property Tax Simulator (through 2019, Chicago only)

The excel file below is the Cook County Assessor's Property Tax Rate Simulator tool. The tool simulates effective tax rates and total property tax bills for user-input property values for single-family homes and condos (200-class), commercial apartments (300-class), and commercial and industrial (500-class) properties in the City of Chicago. To accomplish these simulations, the workbook contains data and models to demonstrate how individual assessments, levies, and overall tax bases interact to produce a Chicago tax bill.

This tool is for educational purposes only. The Assessor’s office releases the tool without any representations or warranties of any kind, whether express or implied. Any data, figures, or amounts contained within the tool, used by the tool, or produced by the tool are solely for illustrative purposes. Any results produced by this tool as distributed are not intended to be predictive and should not be relied upon for any business or commercial purpose. They merely demonstrate the tool’s features. The Assessor’s office expressly disclaims any liability for any entity’s reliance on this tool.

These simulated tax bills do not take into account effects of homeowner exemptions and do not apply to properties inside of Special Service Areas (SSAs). The tool uses data about taxing districts and TIFs in place for the 2017 and 2018 tax years. The data driving this tool did not directly produce any tax bills, and all inferences drawn from this data should be considered purely speculative. We also strongly recommend reading the Technical Documentation for this tool.
