Language is filed for a constitutional amendment that would allow the Illinois Legislature to enact a graduated income tax, and the Illinois Senate Executive Committee is scheduled to take up the matter Wednesday.

The full text of the amendment reads: “The General Assembly shall provide by law for the rate or rates of any tax on or measured by income imposed by the state. In any such tax imposed upon corporations the highest rate shall not exceed the highest rate imposed on individuals by more than a ratio of 8 to 5”
