New data from the Census Bureau appear to lend support to Arizona’s reputation as a “low tax state,” ranking it 35th nationally in taxes collected as a share of personal income.1 But focusing on the state’s overall tax revenues has led many observers to overlook the fact that different taxpayers experience Arizona’s tax system very differently. In particular, the poorest 20 percent of Arizona residents pay significantly more of their income (12.9 percent) in state and local taxes than any other group in the state.2 For low-income families, Arizona is far from being a low tax state. In fact, only four states tax their poorest residents more heavily than Arizona.
