This choropleth map illustrates the effective tax rates for the bottom 20% of income earners across the United States. The data reveals significant disparities in tax burdens, with Washington state imposing the highest rate at 17.8%, largely due to its reliance on sales taxes and lack of personal income tax. In contrast, states like New Hampshire and Delaware have much lower rates at 5.9% and 5.5%, respectively. The map highlights a trend where states with no income tax, such as Texas and Florida, tend to have higher effective tax rates for the poorest residents, often due to higher sales and property taxes. This visualization underscores the regressive nature of tax systems in certain states, where the poorest residents bear a disproportionately high tax burden compared to wealthier individuals. The average effective tax rate for the bottom 20% is 11.4%, indicating a substantial financial impact on low-income households. Such insights are crucial for policymakers aiming to address tax equity and economic inequality across the nation.
