The Illinois House has endorsed the idea of switching to a graduated income tax. Democrats who control the House voted 61-52 Tuesday on a resolution calling for the change. Switching from Illinois’ flat income tax would require a constitutional amendment. The earliest voters could consider that would be 2020. Democratic candidate for governor J.B. Pritzker has called for a progressive tax. It would tax wealthier people at a higher percentage than those with lower incomes. Currently all individuals pay 4.95 percent.
