You can go to the Institute on Taxation and Economic Policy for Arkansas-specific information. Arkansas does not make the "terrible ten" most regressive states, where the bottom 20 percent pay almost seven times the percentage of their incomes in taxes as the wealthy. But it doesn't perform very well. See graphic below. Note that the people excluded from any benefits of Gov. Hutchinson's income tax plan — those making less than $21,000 — account for roughly 40 percent of Arkansas taxpayers. His plan offers no benefits for those making more than $80,000 either, however. Roughly half of taxpayers will get some savings.
