Springfield (IRN) – Illinois lawmakers are one step closer to putting Gov. J.B. Pritzker’s signature campaign promise on the 2020 ballot: A proposed change to the Illinois constitution that would allow for higher income tax rates on higher levels of income. The Senate passed the measure 40-19. Republicans, who are a super-minority in the chamber, were unanimous in opposition. Both chambers need to approve the measure with a three-fifths vote before it is placed on the ballot in the fall of 2020. It would need approval from 60 percent of the voters choosing to vote on that question or half of all voters participating in the election. Pritzker has proposed the change as a way to make the state’s income tax “fair” in that it would tax people with the ability to pay more while opponents call the change a blank check for lawmakers to hike taxes on smaller groups of people without fearing the political backlash that they otherwise would with a flat income tax.
