Illinois Considers Further Income
Tax Increases as Temporary Tax
Nears Expiration
By Lyman Stone
Economist
Key Findings
*  Illinois' State Business Tax Climate Index score could fall to 44th,
from 31st currently, if the proposed progressive income taxes are
passed, which indicates a tax climate less supportive of economic
growth
*  Illinois already fell from 17th over the last few years with several
rounds of tax increases, which did not succeed in alleviating
Illinois' financial situation or improve the economy
*  Higher and more progressive income taxes generally contribute
to worsening economic performance
Illinois significantly raised taxes in 2011 in an attempt to address its $8.5 billion backlog
of unpaid bills and other financial difficulties. The state raised its flat individual income
tax from 3 percent to 5 percent and increased the corporate income tax from 7.3 percent
to 9.5 percent.1 The 2011 tax increases have generated between $7 billion and $8 billion
in added revenue each year.2
In 2015, the tax increases are scheduled to partially sunset, with the individual income tax
dropping from 5 percent to 3.75 percent and the corporate income tax dropping from 9.5
percent to 7.75 percent (see Table 1). In 2025, the individual income tax is scheduled to
drop further to 3.25 percent and the corporate income tax to 7.3 percent.

Tax Rate, TAx FOUNDATION FISCAL FACT No. 256 (Jan. 13, 2011), http://taxfoundation.org/article/illinois-approves-
sharp-income-tax-increase-fourth-highest-corporate-tax-rate. Illinois' corporate income tax consists of a net
income tax (currently 7 percent) and a property replacement tax imposed on corporate income (currently
2.5 percent). Reference sources that cite Illinois' corporate income tax, including the Illinois Department of
Revenue, report it as a combined tax.
