When Illinois voters head to the polls on Nov. 3, 2020, they will vote on an amendment to the Illinois Constitution which would allow state lawmakers to impose a graduated income tax.

Currently, the state constitution mandates that income tax be levied at a flat rate across all incomes.

Voting ‘yes’ means support for changing to a graduated income tax, and voting ‘no’ signals opposition to a graduated income tax.

But what exactly is a graduated income tax? And how will it affect your taxes? Sun-Times politics reporters Tina Sfondeles and Rachel Hinton put together a guide of everything you need to know before voting on the issue.


What is a graduated income tax?

The specific progressive income tax Gov. J.B. Pritzker has proposed would raise taxes only on people who earn $250,000 or more a year — incomes between $250,000 and $500,000 would be taxed at 7.75 percent. It would maintain the current tax rate of 4.95% on incomes between $100,000 and $250,000. And it would reduce the rate on incomes of $100,000 or less.

Income from $500,000 to $1 million would be taxed 7.85 percent and income over $1 million would be taxed 7.99 percent. The corporate tax rate within the package would also be raised to 7.99 percent.

Voters will not be voting on the specific taxes rates or brackets, but rather, on amending the Illinois Constitution to allow for such a system to be implemented. Currently, the Illinois State Constitution requires that taxes based on income must be levied at non-graduated rates.

Democrats have said the new personal income tax rates would bring in $3.57 billion, and the new corporate tax rate would bring in $350 million.

The current income tax levied on all taxpayers is 4.95%. The flat tax rate, which has fluctuated over the years, has been part of the Illinois constitution since 1970, a year after income tax was first enacted in Illinois. With a constitutional change, the Pritzker administration estimates that 97% of Illinois residents will see at least a modest decrease in their income taxes.

Why is there a referendum? Why is this coming up for a vote?

The Illinois Constitution lays out the rules for how an amendment introduced in the Legislature can be adopted. To become part of the constitution, a proposed amendment must be approved by either 60 percent of those voting on the question or a majority of those voting in the election.
