State tax on the gain
Arizona taxes capital gains as ordinary income at its flat 2.5% rate — among the lowest income-tax rates in the country. The state also allows a 25% subtraction on long-term gains from assets acquired after 2011, pushing the effective rate on qualifying gains below 2%. The state layer here is real but small; the federal bill is the story.
Does Arizona recognize 1031 deferral?
Yes. Arizona conforms to the federal treatment of like-kind exchanges — a valid federal 1031 defers Arizona tax with no separate state election or form beyond your normal return.
Withholding at closing
Arizona is gentler than its neighbors here: there is no broad state withholding regime targeting investment-property sales by residents, and exchange transactions close without a state-level holdback in the ordinary case. (Out-of-state sellers should still confirm current escrow practice with their closing agent — withholding rules are the kind of detail that changes.)
Exchanging into another state
Arizona has no California-style annual tracking form for gains exchanged out of state. Deferred gain from Arizona property that is eventually recognized may still be reportable to Arizona under source rules, but there is no yearly filing chore in the meantime. As always, exchanging into Arizona from a clawback state means the origin state's claim rides along.
