Taxpayers at different income levels experience state and local tax policy in very different ways. In Washington, for example, the lowest 20 percent of families have an average effective state and local tax rate (17.8 percent) that is nearly six times higher than the average rate paid by the top 1 percent of earners (3 percent). Forty-five states assess a higher tax rate on low-income families than the rich. This map shows the ratio of state and local tax rates paid by low-income families v. the top 1 percent.
