TIFs (Tax Increment Financing) freezes the amount of property tax dollars that go to schools and other public services in a TIF district for 23 years at the current value while capturing all tax increases into a slush-fund typically used for corporate welfare and political back-scratching. In the city of Chicago, 163 TIF disctricts take in about $500 million a year but individuals don't see it reported on their taxes.
To answer that question, you'll first have to first find your Property Index Number (PIN) from the Assessor and then use it to look up property taxes paid to TIFs through the County Clerk David Orr's website.
