ITEP Tax Inequality Index
ITEP’s Tax Inequality Index measures the effects of each state’s tax system on income inequality. According to this measure, Illinois has the 8th most regressive state and local tax system in the country. Income disparities are larger in Illinois after state and local taxes are collected than before. (See Appendix B for state-by-state rankings and the report methodology for additional detail.)
