It likely is no coincidence that three of the six states with the highest tax burden on the poor also don't have state income taxes. Washington state has the highest state and local tax burden on the poor at 16.9 percent of their income, according to a study by the Institute on Taxation and Economic Policy. In contrast, the top 1 percent of Washington residents pay 2.8 percent of their income on state and local taxes. Other no-income-tax states in the top six were Florida at No. 3 (13.3 percent burden on the poor) and Texas at No. 6 (12.6 percent). In Kansas, the bottom 20 percent of residents paid 10.3 percent of their income on state and local taxes last year, compared with 3.9 percent for the top 1 percent. Recent Kansas income tax cuts increased the tax burden on the poor while significantly reducing taxes on the wealthy.
