Here’s one reason from Reboot Illinois why jobs are leaving Illinois:
That disadvantage may already exist in Illinois’ business tax rate, which in 2011 rose from 7.3 to 9.5 percent (2 percent of that figure comes from the personal property replacement tax). That’s well above the rate of all its neighboring states except Iowa, which uses a graduated rate of 6 to 12 percent. The corporate rate in Illinois will drop to 7.75 percent in 2015 unless the legislature and governor pass legislation to extend it. A second drop in 2025 is scheduled to return it to 7.3 percent.
But it won’t happen because Illinois politicians already are talking about extending the “temporary” tax.
