The infrastructure plan you are both referencing below is what Governor Pritzker drafted. The plan that this thread is referencing is a bill which is currently in the Illinois Senate and is being read for a 2nd time today. This bill still states the EV registration fee will be raised to $1,000 per year. You can view the status of the bill by clicking here. Based on the voting patterns of Illinois lawmakers, this bill has a very good chance of passing the Senate very soon. Once the bill has passed the Senate, I believe it would end up on Pritzker's desk to be signed into law. If Pritzker signs it into law as is, we would be paying $1,000 per year for registration on EV in IL.
Looks like the new draft is at $250 for EVs, and progressive amount based on age of the car for gas cars (if I understand correctly):
