If you want to know why taxes are going through the roof, check out the city’s latest propaganda about tax increment financing.

This two-page primer, recently posted on the city’s Web page, is billed as “The ABC’s of TIF: Benefitting all of Chicago.” Filled with mistakes, half-truths, and erroneous assertions, it would probably earn an F for its writer if it were submitted in a college course on municipal financing. Either planning officials don’t understand the most important program they oversee or they’re purposely misleading the public. I’m not sure which would be worse.

I have to give them credit for one thing: along with the primer they’ve posted brief profiles of each TIF district. TIF critics have been pestering the city to put this info on line for years.
