With Illinoisans increasingly likely to move, Pritzker’s tax plan would send more moving vans toward the state line, and hit the gas.

Illinois Gov. J.B. Pritzker is pushing a progressive state income tax without delivering the numbers to prove his promises. The numbers available from other states make it clear a progressive tax will hurt Illinois’ economy.

The Senate Executive Committee voted on an amendment scrapping Illinois’ constitutional flat income tax protection. But lawmakers have yet to introduce a bill outlining what the rates would be.

Most business is mobile. Most of Illinois is close to another state. Add a progressive state income tax and watch businesses such as Piasa Motor Fuels cross the bridge to Missouri.

Pritzker’s first budget address exalted the graduated income tax as a solution to the state’s fiscal problems. Despite evidence to the contrary, the governor is urging state lawmakers to speedily advance the measure.
