Gov. JB Pritzker has tied his second-year state budget proposal to the unfinished marquee policy initiative of his first year – a constitutional amendment that allows the state to impose higher income tax rates on higher income earners.

If voters approve that graduated income tax initiative in the November general election, Pritzker is asking for a roughly $1.6 billion increase in state general revenue fund spending for the upcoming fiscal year, which begins July 1.
