Moving from Arizona to Indiana: Residency, Taxes, and What to Prove

In Arizona

Arizona's Phoenix and Tucson hospital systems make it one of the largest travel nurse markets in the country. A nurse who is actually Arizona-domiciled and takes Arizona contracts is simply an Arizona resident under ordinary rules. A nurse who claims Arizona as a tax home while working travel assignments elsewhere needs a genuine, regularly used Arizona residence with duplicated living expenses, or the stipend portion of their pay risks being reclassified as taxable wages if audited.

In Indiana

Indiana applies its ordinary domicile and 183-day/permanent-residence tests to a travel nurse the same as anyone else: a nurse not domiciled in Indiana who keeps a permanent Indiana residence and is present more than 183 days becomes an Indiana resident on worldwide income for that year, plus the applicable county tax. The more frequent exposure runs the other way, where a nurse claims a Florida or Texas tax home while actually renting in Indiana for most of an assignment; Indiana taxes nonresident wages for days actually worked in the state regardless of the claimed tax home.

In Arizona

Arizona is home to the Cardinals, Suns, Diamondbacks, and the Coyotes' successor tenant at Mullett Arena, and MLB's Cactus League spring training in March adds a significant block of extra duty days for every visiting team's roster. Arizona applies standard duty-day allocation to nonresident athlete income, but because the flat rate is only 2.5%, Arizona produces one of the lowest jock-tax burdens of any state that taxes athlete income at all.

In Indiana

Indiana taxes nonresident professional athletes using the standard duty-day formula applied across nearly all income-tax states: total season compensation multiplied by the ratio of Indiana duty days (games, practices, and mandatory team functions in the state) to total duty days for the season. This applies to visiting NFL and NBA teams playing the Colts and Pacers in Indianapolis, and Indiana's flat, comparatively low rate means the dollar amount at stake per game is smaller than in higher-rate states, though the filing obligation is the same.

In Arizona

This is Arizona's signature scenario: the state's own nine-month (roughly 274-day) presumption explicitly allows spending a large chunk of the year in Arizona without automatically becoming a resident. Large numbers of California and Midwest retirees winter in the Phoenix and Tucson areas from October through April while keeping their prior-state domicile, but they need to track their total Arizona days against the 274-day threshold and remember their origin state runs its own, separate presumption pointing the other direction.

In Indiana

The Indiana snowbird risk runs through the same domicile-abandonment presumption that protects year-round Indiana residents: a retiree who keeps a permanent Indiana residence, continues to vote in Indiana, or keeps the homestead deduction active while wintering in Florida is presumed not to have abandoned Indiana domicile. Separately, spending more than 183 days in Indiana in a year while maintaining a permanent Indiana residence independently triggers Indiana residency regardless of domicile intent.

In Arizona

Arizona has no convenience-of-employer rule. A nonresident who performs all their work physically outside Arizona for an Arizona-based employer is not Arizona-taxed on those wages. Arizona also has a narrow reciprocal withholding exemption (Form WEC) with California, Indiana, Oregon, and Virginia: residents of those four states working in Arizona can request their Arizona employer withhold no Arizona tax, though the arrangement runs one direction and doesn't create general two-way income tax reciprocity.

In Indiana

Indiana has no convenience-of-the-employer rule. A nonresident who works remotely from another state for an Indiana-based employer is generally not taxed by Indiana on those wages, since Indiana sources employee compensation to where the work is physically performed rather than to the employer's location.

In Arizona

Arizona follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. Nonresident military stationed in Arizona under orders don't become Arizona residents from the posting alone, and their military pay isn't Arizona-taxed if domiciled elsewhere. Arizona also fully exempts military retirement pay for its own domiciled veterans.

In Indiana

Indiana follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose domicile was Indiana before entering service remains an Indiana domiciliary regardless of duty station unless they affirmatively establish a new domicile, while a servicemember stationed in Indiana on orders, and a qualifying spouse, does not become an Indiana resident solely because of the posting; Indiana also allows a deduction for certain military retirement income.

In Arizona

American Airlines operates a major hub and crew base at Phoenix Sky Harbor (PHX). Federal law (49 U.S.C. §40116) limits taxation of air carrier employees to their state of residence and any state where they earn more than 50% of pay, which matters directly for Arizona-based crew flying national routes.

In Indiana

Federal law (49 U.S.C. §40116) limits states to taxing airline employee compensation only in the employee's state of residence and any state where more than 50% of pay is earned, protecting flight crew based at Indianapolis International who are domiciled outside Indiana from full-income Indiana taxation based solely on their duty station.
