The 2015 Who Pays: A Distributional Analysis of the Tax Systems in All Fifty States (the fifth edition of the report) assesses the fairness of state and local tax systems by measuring the state and local taxes that will be paid in 2015 by different income groups as a share of their incomes. The report examines every state and the District of Columbia. It discusses important features of each state’s tax system and includes de­tailed state-by-state profiles that provide essential baseline data to help lawmakers understand the effect tax reform proposals will have on constituents at all income levels.

The report includes these main findings:

Combining all state and local income, property, sales and excise taxes that Americans pay, the nationwide average effective state and local tax rates by income group are 10.9 percent for the poorest 20 percent of individuals and families, 9.4 percent for the middle 20 percent and 5.4 percent for the top 1 percent.

Six of the 10 most regressive states derive roughly half to two-thirds of their tax revenue from sales and excise taxes, compared to a national average of roughly one-third . Five of these states do not levy a broad-based personal income tax (four do not have any taxes on personal income and one state only applies its personal income tax to interest and dividends) while four have a personal income tax rate structure that is flat or virtually flat.

State personal income taxes are typically more progressive than the other taxes that states levy (e.g property, consumption). Sales and excise taxes are the most regressive, with poor families paying almost eight times more of their income in these taxes than wealthy families, and middle-income families pay­ing five times more. Property taxes are typically regressive as well, but less so than sales and excise taxes.

Personal income taxes vary in fairness due to differences in rates, deductions, and exemptions across states. For example, the Earned Income Tax Credit improves progressivity in 25 states and the District of Columbia, while nine states undermine progressivity by allowing taxpayers to pay a reduced rate on capital gains income, which primarily benefits higher-income households.
