For the past three decades, tax increment financing (TIF) has been the primary public financing tool used by the City of Chicago to spur local economic development. During this time period, TIF advocates and opponents alike have attempted to understand TIF’s impact on taxing jurisdictions that overlap TIF district boundaries. Interested parties have raised important questions. How much, if any, has the price of this economic growth been paid for by local schools and other taxing districts? How has the use of TIF in Chicago impacted taxpayers on the whole, both locally and throughout the state?
