Key Findings:

  • New Illinois Gov. J.B. Pritzker (D) has proposed sweeping changes to Illinois’ tax code, advocating a constitutional amendment to permit a graduated-rate income tax and proposing a new rate and bracket structure.
  • Under the proposal, corporate income would be taxed at 10.45 percent, the third-highest rate in the nation, while pass-through business income would be taxed at a top rate of 9.45 percent, the fourth highest such rate nationwide.
  • The proposal diverges sharply from ideal—or even typical—income tax structure. It omits inflation indexing (resulting in “bracket creep”), creates a marriage penalty, and includes a recapture provision which subjects the entirety of a taxpayer’s income to the top marginal rate once they reach that bracket.
  • The neighboring states of Indiana, Iowa, Kentucky, and Missouri have all cut income taxes in recent years, while Illinois may be headed in the opposite direction.
  • The governor’s proposed tax rates are merely notional; should voters permit a graduated-rate income tax, there are compelling reasons to believe that rates may climb even higher, and that more taxpayers would be subjected to higher rates.
  • Were the proposal implemented, Illinois is projected to decline from 36th to 48th on the State Business Tax Climate Index, which measures tax structure.
