SPRINGFIELD — A budget plan that includes a hike in the state income tax, an expansion of the sales tax billions in cuts are among the key budget recommendations that rank-and-file lawmakers have sent to top legislative leaders.

A bipartisan working group dubbed the “Budgeteer” group proposed the package to the leaders on Wednesday.

Gov. Bruce Rauner said he is generally “cheering” the group’s work, but a top Republican leader cautioned that they are not “anywhere close to a deal.”

Under the proposal, the state would bring in roughly $5.4 billion through a combination of tax increases. That includes raising the personal income tax rate from 3.75 percent to as much as 4.85 percent, expanding the sales tax to certain services and eliminating some corporate tax breaks.

Meanwhile, spending would be cut by roughly $2.5 billion. That includes a reduction in health care spending for the poor, saving $750 million in pension costs by ending late-career salary spikes and requiring schools and universities to pick up employee pension costs above a $180,000 yearly salary, along with unspecified changes in how the state buys goods and services. In addition, the state would no longer be required to pay back $450 million it borrowed from special funds last year to plug a separate budget hole.

The state also would borrow $5 billion to pay down a backlog of bills expected to hit $10 billion by July 1. That debt has skyrocketed this year, in part because of the tax rollback, which created a $4 billion hole that only grew worse during the impasse.

That’s because while there isn’t a full budget, more than 90 percent of government operations have been kept running through various laws and court orders, but big-ticket items like higher education, prisons and social services have only been partially funded or not funded at all.

The loan would be paid back over five years, with the goal that the state would carry a more manageable load of unpaid bills of about $3 billion a year.
