Arizona levies a flat 2.5% income tax rate on all income, including capital gains. This is one of the lowest state income tax rates in the nation and was reduced from a graduated system in recent years, making Arizona increasingly attractive for real estate investors and retirees selling appreciated property.
At 2.5%, Arizona's capital gains tax is significantly lower than neighboring states like California (13.3%) and New Mexico (5.9%), though higher than Nevada (0%). On a $150,000 taxable gain, you would owe just $3,750 in state tax compared to nearly $20,000 in California. This tax differential has been a key driver of Arizona's real estate boom as buyers relocate from higher-tax states.
Arizona does not distinguish between short-term and long-term capital gains at the state level. Both are taxed at the flat 2.5% rate. However, the federal distinction still applies, so holding property for more than one year before selling remains advantageous for the federal portion of your tax bill.
The Phoenix metro area, Tucson, and Scottsdale have all seen significant appreciation in recent years, which means many sellers face gains that exceed the federal exclusion. Arizona's low rate provides some cushion, but sellers with gains above $250K (single) or $500K (married) should plan for both federal and state tax obligations.
