It could bring a new Bears stadium to Arlington Heights.
It passed in the House this week; now it's up to the Senate to take action.
"If there is not true progress that gets made, if it's not obvious that the Senate is moving in the right direction, that will make it challenging. We're all working together; the Bears want to be in Illinois. I think that's really what their choice would be, if we can put a bill forward that makes sense," Pritzker said.
The governor is calling for expediency.
"I can tell you that there is a need to, you know, for speed here; we need to move somewhat expeditiously," Pritzker said. "It's not going to, you know, completely flip the script. And all of a sudden, on that date, you're going to see, you know, Indiana is being chosen if Illinois doesn't have a bill."
Pritzker says, to satisfy the Bears changes need to be made, like removing the amusement tax. Some Democratic lawmakers say the entire bill needs to change or at least slow down.
The Bears have owned the former home of the Arlington Race Track for more than three years now with plans to build a multibillion dollar stadium.
Under the "megaprojects" bill, the Bears wouldn't have to pay traditional property taxes. Instead, they'd work out a deal with local leaders to make what's called a "payment in lieu of taxes," or PILOT. Then, by law, about half of that money would go back into property tax relief for homeowners.
Some say now is not the time to be giving tax relief to the Bears and other large developers.
It's not just the Bears who could score. Big Illinois construction projects worth $100 million or more would benefit from some tax relief under the bill. But, the legislation is far from perfect. The Senate has work to do to satisfy many interests.
Gov. Pritzker argues the bill isn't just a Bears bill. He says providing property tax relief to big developments will spur economic growth for all of Illinois.
"When companies come to Illinois, they go negotiate with local governments about their property taxes. And if they can't get a good deal, they go to another state. And so we're just trying to create a process for that to happen," Pritzker said.
Chicago Democrat Kelly Cassidy voted against the bill. While the legislation provides some property tax relief to homeowners and possibly more funding for education, Cassidy says now is not the time to give big developments tax relief.
"I'm advocating for my folks who can't afford their rent, who are getting cut off from healthcare, who, you know, need our schools to be stronger and better for their kids who want to be safe on the streets. Nothing that is in that bill adds to any of those priorities," Cassidy said. "This is not year to magically, to find a way to help a corporation that Forbes values in the billions."
The team is expected to update NFL officials on stadium progress next week.
The end of the legislation session is May 31.
