CHICAGO (AP) — Gov. J.B. Pritzker is scheduled to sign the state budget and legislation related to enacting a graduated income tax in Illinois.

Pritzker’s office says he will sign the measures Wednesday afternoon at the Thompson Center in downtown Chicago. They are pillars of what the first-year governor has called one of the most “ambitious and consequential” legislative session in state history.

The nearly $40 billion budget increases spending for education and the state’s child welfare agency. It fully funds the state’s $9 billion pension contribution and borrows $1.2 billion to pay $6.7 billion in overdue bills. The budget also includes a $1,600 annual pay raise for lawmakers.

The income tax measure adds a constitutional amendment question to 2020 ballots asking voters whether they want rates to increase with income.
