How a graduated rate income tax would help reduce after-tax income inequality in Illinois

Release: May 22, 2019

Since 1979, the nation has seen a rapid and significant increase in income inequality between low- and middle-income Americans on the one hand, and the wealthiest one percent on the other. Over that time span, the bottom 99 percent of American households saw their incomes increase by an average of just 14 percent after inflation. Meanwhile, the wealthiest one percent saw their inflation-adjusted incomes balloon by 175 percent on average—or fully 12.5 times more than the income growth realized by everyone else.

Release: February 17, 2015

Many know that on January 1, 2015, the temporary increases made to the state’s income tax rates that became law under the Taxpayer Accountability and Budget Stabilization Act of 2011 (TABSA) began to phase-down. On that date, the personal income tax rate declined from 5 percent to 3.75 percent, while the corporate rate went from 7 percent to 5.25 percent. What is not well known is: (i) who benefited most from the cut to the personal income tax rate under TABSA, and (ii) whether or not that tax cut can reasonably be expected to stimulate the Illinois economy. This Issue Brief reveals that the state's highest income earners will benefit disproportionately from the income tax rate phase-down, worsening income inequality and failing to stimulate the state's economy.
