Illinois voters rejected graduated income tax rate

Multistate Tax alert | November 4, 2020

This Tax alert provides background on Illinois voters rejected graduated income tax rate.


On November 3, 2020, Illinois voters voted against the ratification of a new state constitutional amendment which would have allowed the General Assembly to enact a graduated income tax rate.1 If the amendment was ratified, Public Act 101-0008, signed into law on June 5, 2019 by Governor J.B. Pritzker, would have instituted a new graduated income tax structure for individual and joint filers ranging from 4.75 percent to 7.99 percent and would have raised the corporate income tax rate to 7.99 percent. The Illinois tax rates will remain at the current rates unless and until further legislative action is taken. The current Illinois income tax rate is 4.95 percent for individuals and 7 percent for corporations plus 2.5 percent personal property replacement tax for a total corporate tax rate of 9.5 percent.2
