The budget plan that Rauner vetoed would have the state spend more than $36 billion on primary and secondary education, colleges and universities, social services, medical care for the poor and other government functions, with nearly $5 billion in new taxes to help pay for it. The personal income tax rate would rise from 3.75 percent to 4.95 percent. The corporate tax rate would go from 5.25 percent to 7 percent. The plan also would have the state pay down about half of the nearly $15 billion pile of unpaid bills through a combination of borrowing and using cash from other state accounts.
