"Today represents another important step in the negotiations, and we look forward to continuing those conversations with stakeholders in the House as well," Abudayyeh said in an emailed statement. "Governor Pritzker's focus on making our system more fair means that 97 percent of Illinois taxpayers will pay the same or less in income taxes, while only those making more than $250,000 will pay more."

During the committee hearing Tuesday afternoon, Hutchinson said her proposal "retains that underlying principle."

"In the absence of this, we have a noted and pretty much agreed upon $3.2 billion ... structural (budget) deficit," Hutchinson said. "And if we don't do this, then we can raise taxes on everybody, or we can cut 15 percent across the board, or we can argue that the status quo and the lack of investment that we're making in all the things that we all care about and all agree on should stay as broken as it is today."

Hutchinson said the lower income threshold for single filers was meant to address criticisms of the so-called marriage penalty that Pritzker's proposal would have created.
