The Illinois Economic Policy Institute and the University of Illinois at Urbana-Champaign have jointly released a one-page fact sheet on the impacts of switching to a progressive income tax in Illinois.
Governor J.B. Pritzker and the General Assembly have debated whether to amend the Illinois Constitution to allow the state to replace its flat-rate income tax system with a progressive (or “graduated-rate”) income tax. Illinois is currently one of only 8 states that has a flat tax, while 33 states have progressive tax systems.
