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. 
Very Low Income Tax, but High Sales and Excise Taxes According to the Census Bureau, Arizona’s state and local tax collections totaled 9.8 percent of personal income in fiscal year 2011, well below the national average of 10.6 percent. One reason for Arizona’s low ranking is that the state’s personal income tax collections as share of personal income are 43 percent below the national average. 
But having low personal income taxes comes at a cost. In order to pay for state and local government services, Arizona’s sales and excise taxes are 27 percent above the national average. Measured relative to personal income, Arizona has the 8th highest sales and excise tax collections in the entire country. According to the Institute on Taxation and Economic Policy (ITEP), the poorest 20 percent of Arizona households spend 8.3 percent of their income on these taxes, compared to just 1.1 percent of income for the state’s most affluent residents.
A High Tax State for the Poor While Arizona’s state and local taxes average 9.8 percent of income, differently positioned taxpayers experience Arizona’s tax system very differently. For the top 1 percent of Arizona households (a group with an average income over $970,000), the Grand Canyon State’s decision to levy low income taxes has indeed been an enormous boon. This group pays just 4.7 percent of their income in Arizona taxes—the 18th lowest (or 32nd highest) state and local tax bill for this group in the entire country. 
But while Arizona’s reputation as a “low tax state” is accurate for wealthy households, it bears little resemblance to reality for the state’s less affluent residents. The poorest 20 percent of Arizona taxpayers (earning an average income of $12,200 per year) actually face the 5th highest state and local tax bill in the entire country, at 12.9 percent of income. Similarly, among the next 20 percent of taxpayers (with an average income of $27,000 in Arizona), state and local taxes are the 5th highest nationally. 
Arizona’s imbalanced tax system, with its heavy reliance on sales and excise taxes, is pushing the state’s impoverished taxpayers deeper into poverty. The state’s low reliance on personal income taxes has been a major contributor to its reputation as a “low tax state,” but it comes at a steep price in terms of higher tax rates on low-income families.
