Tax Increment Financing is controversial. But there is no question that it is a great way to build tax base and jobs. The Southtown TIF is the oldest TIF in the City of Peoria and one of the oldest in Illinois. The graph and chart show that the value of real estate within the TIF grew much faster then the City and District 150. In 2013, the TIF will be completed, and the tax revenues will go to all the local goverments.
