IL Democrats proposing 2nd highest Small Business Tax in U.S.



State Rep. Lou Lang’s progressive-tax scheme would put successful small businesses in Illinois on the defensive, not just against small businesses in other states but also against corporate competitors in Illinois.

Lang’s tax bill, House Bill 689, would amend the Illinois income-tax code to nearly triple the top personal income-tax rate, bumping it up to 9.75 percent from 3.75 percent. This would result in Illinois having the second-highest small business tax rate in the U.S., and would put noncorporate businesses in Illinois at a significant tax disadvantage against corporations.
