A broad majority of Illinois voters support major changes to the state income tax, favoring a system where the wealthy pay more. That’s according to new survey data from NPR Illinois and the University of Illinois Springfield.

After years of campaigning, Democrats are moving ahead with a plan to change Illinois’ tax system. On Tuesday they formally introduced the language they want to change in the Illinois Constitution.

Illinois Governor J.B. Pritzker said Thursday he’s confident the legislature will approve a graduated income tax.

A long time ago, the tax was proposed by the GOP and opposed by Democrats. It became law, but it didn't last long.

Illinois House Speaker Michael Madigan says he expects to work “very well” with Governor-elect J.B. Pritzker and will support two of Pritzker’s major proposals.
