Illinois voters rejected a constitutional amendment to allow for a graduated income tax by a vote of 55% against to 45% in favor.
The ballot measure would have repealed the state’s constitutional requirement that the state’s personal income tax is a flat rate across income. Instead, the ballot measure would have allowed the state to enact legislation for a graduated income tax.
More than $121 million was raised by supporters and opponents of the measure. Supporters raised $60.33 million, including $56.5 million from Gov. J.B. Pritzker. Opponents raised $60.86 million, including $53.8 million from Citadel CEO Kenneth C. Griffin.
This measure was the most expensive of 2020 outside of California.
