Crossing a state line into or out of Arizona

Arizona taxes its residents on income earned anywhere, and taxes non-residents on work done inside it. Which return you file depends on which direction you commute.

Arizona borders 4 states. They fall into 2 different situations, and which one applies decides whether you file one return or two.

Where you file a nonresident return and claim a credit

Arizona has no agreement with California, New Mexico and Utah. Work in one of these and you file a nonresident return there, report the same income again to Arizona, and claim a credit for what you already paid. The credit is capped at your Arizona liability, so you are not taxed twice, the combined bill lands at roughly the higher of the two rates. On $70,000, Utah costs the most at $3,150 and California the least at $2,786, $364 between them.

Work state	Its tax	Arizona after credit	Total	Rate that governs
California	$2,786	$0	$2,786	California
New Mexico	$3,140	$0	$3,140	New Mexico
Utah	$3,150	$0	$3,150	Utah

Where the work state takes nothing

Nevada levies no personal income tax, so there is no return to file there and no credit to claim. But Arizona still taxes the wages as a resident. The catch is withholding: an employer in Nevada has no state income tax to withhold, so nothing is taken out for Arizona either. The liability is real and nothing is being set aside against it, which usually means Arizona estimated payments.

What Arizona itself takes across a salary range

A single filer, taking the standard deduction. This is the figure every arrangement above is measured against, the tax Arizona charges a resident, whether the work happened inside the state or over a line:

Wages	Arizona tax	Effective rate
$45,000	$1,125	2.50%
$70,000	$1,750	2.50%
$120,000	$3,000	2.50%

Coming the other way: living in a no-income-tax state, working in Arizona

Nevada border Arizona and levy no personal income tax of their own. A resident of Nevada who works in Arizona has the simplest arrangement on this page and the least room to improve it: Arizona taxes the wages earned inside it, $1,750 on $70,000, there is no home-state return, and so there is nothing to claim a credit against. Living across a border that charges nothing does not reduce the Arizona bill by a cent.

Reciprocity cannot help either, even where Arizona has agreements: reciprocity shifts the income to the home state's return, and a state with no income tax has no return to shift it to.

What Arizona charges as your home state

Arizona applies a single 2.5% rate to taxable income for 2026, so every extra dollar of wages is taxed at the same state rate.

Arizona is a community property state. In community property states, income earned during marriage is generally owned equally by both spouses. This affects QJV eligibility, MFS filing strategies, and retirement account contribution rules.

State income tax on wages only, 2026 rates. Not tax advice, what this does and doesn't cover.
