10 States With the Worst Taxes for Average Joes

The difference between rich and poor Americans has grown dramatically in recent years. As of 2013, the wealthiest 20% of Americans had more income in aggregate than the bottom 80% combined. State and local tax systems play a significant role in redistributing income among people. The nationwide average effective tax rate for the poorest 20% of Americans was 10.9%, roughly double the 5.4% rate for the top 1%. When looking at taxes paid as a share of the income earned, all states have a regressive tax system, which means poorer residents are taxed more than the wealthiest ones. The difference in effective tax rates between income groups, however, varies widely between states. According to “Who Pays? A Distributional Analysis of the Tax Systems in All 50 States,” a report released by the Institute on Taxation and Economic Policy (ITEP), Washington has by far the most regressive tax system nationwide. To identify the 10 states with the worst tax systems for average Americans, 24/7 Wall St. reviewed ITEP’s Tax Inequality Index scores for the 50 states. The index incorporated effective tax rates for the poorest 20%, middle 60%, top 1%, as well as ratios comparing these rates, among other measures. Effective tax rates were based on total state and local taxes as a share of family income for non-elderly taxpayers in all 50 states. ITEP’s model used 2012 income figures, and considered tax laws from 2014 and 2015. Contributions to state revenue by tax type were also provided by ITEP. We reviewed the Gini coefficient from 2013—which is based on pretax income—as well as additional economic data from the Census Bureau’s 2013 American Community Survey.
