The state of Arizona has created a commission to examine their tax code. While the Arizona government argues that not enough tax revenue is being collected, the Goldwater Institute came out with its own policy study showing the opposite: too much money is being taken. Arizona’s revenues have risen faster than the Arizona economy has grown, proving that tax holes don’t exist. However, the state’s tax rates are still not competitive. Texas, Colorado, and Nevada are regional competitors that have more attractive tax structures.
