Cost of living in Arizona
Cost of living in Arizona stands at 100.7, placing it fractionally above the US average of 100 and ranking 17th most expensive nationally. The defining feature of Arizona's tax environment is its flat 2.5 percent state income tax, the lowest flat rate among states that levy an income tax at all. That single number applies across all income levels, so a household earning $120,000 pays the same marginal rate as one earning $35,000. The state also collects a transaction privilege tax at a base rate of 5.6 percent, which functions similarly to a sales tax. At just above the national price level, Arizona offers reasonable overall affordability for a Sun Belt state with strong employment growth. Phoenix has grown into one of the most populous metros in the country, and the associated housing demand has pushed prices up considerably from their post-2008 lows. Tucson and the smaller cities in the state remain more accessible by comparison.

Arizona in context
Phoenix metro housing appreciation has been among the fastest in the US over the past decade, and that trajectory has pulled Arizona's price level upward even as its taxes remain low. Rents in Scottsdale and Chandler now rival parts of the Mountain West that were long considered more expensive. Utility costs add a meaningful year-round expense: air conditioning in Arizona summers can double or triple electricity bills compared with milder climates, a cost that does not show up in the raw price level index but matters significantly to household budgets. Cooler and higher-elevation cities such as Flagstaff carry different cost profiles, with lower cooling costs but higher housing prices relative to their size. For retirees and remote workers, the combination of a low flat income tax, mild winters, and prices near the national average makes Arizona financially attractive, particularly if utility costs are managed through efficient housing.
The closest state above Arizona on price is Virginia at 101.1. Just below sits Illinois at 100.
