Illinois Approves Sharp Income Tax Increase,
Fourth-Highest Corporate Tax Rate
By
Joseph Henchman & Kail Padgitt
Plan Will Raise Individual Income and Corporate Income Taxes
Early on January 12, 2011, the Illinois Legislature narrowly passed a bill that significantly raises individual income and
corporate income taxes.1 Under the plan, Illinois's one-rate individual income tax will rise from 3% to 5%, a 67 percent
increase. The corporate income tax will rise from 7.3%2 to 9.5%, a 30 percent increase, becoming the fourth-highest state
corporate income tax in the United States, and the fourth-highest combined national-local corporate income tax in the
industrialized world.3 Two additional provisions include a reinstatement of the estate tax at the 2001 level and a temporary
suspension of the net operating losses (NOLs) associated with the corporate tax.
The tax increases are projected to raise approximately $6.5 billion per year, and be coupled with additional borrowing.
Illinois has accumulated billions of dollars in unpaid bills and officials have made little progress compared to other states
in producing a structurally balanced budget.4
The income tax increase will be retroactive to January 1, 2011. After four years, the individual income tax will decrease to
3.75%. Then in 2025, the individual income tax rate will drop to 3.5%. The corporate tax will follow a similar schedule of
rate decreases: in four years the rate will be 7.75% and then in 2025 it will go back to the current rate of 7.3%.

immediate neighbors.5 Illinois's low, one-rate individual income tax offers the advantages of simplicity,

2 Some news reports have indicated that Illinois's corporate income tax is currently 4.8%. This does not include a 2.5% property
replacement tax imposed on corporate income. Reference sources that cite Illinois's corporate income tax, including the Tax
Foundation and the Illinois Department of Revenue, report it as 7.3%, including this tax.

(9.990%), Minnesota (9.80%), and Iowa. Iowa has a 120% top rate but its effective rate is lower after accounting for federal
deductibility.
