Moving from Indiana to Arizona: Residency, Taxes, and What to Prove
The top income tax rate drops from 2.95% (flat, state) + county income tax in Indiana to 2.5% in Arizona. Establishing Arizona residency correctly is what protects that benefit.
Residency Tests Side by Side
Indiana uses a 183-day statutory residency threshold, while Arizona uses 274 days. Track both thresholds separately during a transition year rather than assuming they line up.
| Factor | Indiana | Arizona |
|---|---|---|
| Statutory Residency Test | Indiana Code 6-3-1-12 and 45 IAC 3.1-1-21 define a resident two independent ways: an individual domiciled in Indiana during the tax year, or an individual who is not domiciled in Indiana but maintains a permanent place of residence in the state and spends more than 183 days of the taxable year in Indiana. Indiana guidance explicitly notes the 183-day/permanent-residence test is a separate, independent basis for residency, not itself a test for domicile. | Arizona Revised Statutes §43-104 defines a resident as anyone domiciled in Arizona, or anyone who is in Arizona for other than a temporary or transitory purpose. The statute also sets a presumption: an individual who spends in aggregate more than nine months (roughly 274 days) of the tax year in Arizona is presumed a resident, rebuttable with evidence the presence was temporary or transitory. |
| Domicile Test | Under 45 IAC 3.1-1-22.5, Indiana presumes a person has not abandoned Indiana domicile if they maintained a permanent residence in Indiana and satisfy at least one of: claiming a homestead deduction or military tax exemption on an Indiana home, voting in Indiana, occupying an Indiana residence more days of the year than any other single state, claiming a federal tax benefit based on Indiana being the principal residence, or having a place of employment or business in Indiana. Supplementary factors include driver's license and vehicle registration location, dependent claims, mailing address, bank accounts, organizational memberships, and where professional services and valuables are located. | Arizona applies the common-law domicile test described in ADOR Individual Income Tax Procedure ITP 92-1: physical presence in a place combined with intent to make it your permanent home. Domicile, once established, is presumed to continue until affirmatively changed, and the burden of proving a change falls on the person claiming it. |
| Day Count Threshold | 183 days | 274 days |
| Any Part of a Day Rule | Indiana's statute uses 'more than 183 days,' which mirrors New York's and Illinois's phrasing; Indiana guidance does not publish a specific carve-out exempting partial days, and practitioners treat any day with meaningful Indiana presence as counting toward the total absent a documented exception like medical treatment or transit. | ADOR guidance under ITP 92-1 counts any day with any physical presence in Arizona toward the aggregate nine-month presumption count, similar in concept to California's approach, though in practice Arizona applies it with less aggressive enforcement than California. |
| Presumptions | 45 IAC 3.1-1-22.5 creates a presumption against abandonment of Indiana domicile whenever a person kept a permanent Indiana residence and meets at least one of the five primary factors listed above (homestead claim, voting, most-days-in-state, federal filing benefit, or Indiana employment); this presumption is rebuttable but places real weight on continuing to hold any one of those Indiana connections. | ARS §43-104's nine-month (roughly 274-day) presumption of residency, rebuttable by evidence the time in Arizona was temporary or transitory. |
| Safe Harbors | None published | None published |
Leaving Indiana
Indiana is not generally characterized by practitioners as an aggressive residency-audit state compared with its neighbors; its flat, comparatively low income tax rate reduces the dollar incentive for the Department of Revenue to pursue contested domicile cases the way high-rate states do. The Department does issue individual Letters of Findings resolving residency disputes, including cases finding a taxpayer was not subject to Indiana tax because they had established domicile in another state based on objective evidence like a home purchase and filings there, showing Indiana does examine claims on a case-by-case basis rather than running the kind of broad, headline exit-audit programs seen in New York or Minnesota.
Trailing Income
Indiana has no convenience-of-the-employer rule, so a former resident who works remotely from another state for an Indiana-based employer is generally not taxed by Indiana on those wages once genuinely nonresident, since Indiana sources employee compensation to where the work is physically performed. Indiana does continue to tax Indiana-source income after departure, including gain on Indiana real property and a departing resident's share of Indiana business income for the period they operated in the state.
Part-Year Filing
Form IT-40PNR, Indiana Part-Year and Full-Year Nonresident Individual Income Tax Return, is used for the year a taxpayer moves into or out of Indiana. It allocates income between the Indiana-resident portion of the year and the nonresident portion, and also handles the county income tax allocation based on county of residence or principal work location as of January 1 or as of the move date, depending on the specific county tax rule that applies.
Enforcement Methods
Common Exit Mistakes
Establishing Arizona Residency
| Action | Agency | Deadline |
|---|---|---|
| Get an Arizona driver's license | Arizona MVD | within 30 days of establishing residency |
| Title and register vehicles in Arizona | Arizona MVD | within 15 days of establishing residency |
| Register to vote | Arizona Secretary of State | 29 days before an election |
Declaration of Domicile
Arizona has no formal declaration-of-domicile filing. Domicile is shown through conduct: purchasing or leasing an Arizona home, obtaining an Arizona driver's license, registering to vote, and opening Arizona bank accounts.
Homestead
Arizona's homestead exemption automatically protects up to $425,200 (as of January 2025, adjusted annually for inflation under ARS §33-1101) of equity in a primary residence from most creditors, with no filing required. Because it's automatic and adjusts every year, it's a weaker domicile-evidence signal than a state requiring an affirmative recording, but ADOR and other agencies can still cross-check ownership records against claimed nonresident status.

New Resident Tax Traps
Arizona taxes a new resident's worldwide income starting the date residency begins, requiring the Form 140PY apportionment for the year of the move. Because Arizona closely conforms to federal adjusted gross income, most federal timing issues around moving (like relocation-related deferred compensation) flow directly onto the Arizona return without separate state-specific adjustment.
What Changes on Tax
Indiana Top Rate
2.95% (flat, state) + county income tax
Arizona Top Rate
2.5%
Moving from Indiana to Arizona drops the top marginal income tax rate from about 2.95% to about 2.5%, a reduction of roughly 0.45 percentage points.
Withholding Reciprocity
Indiana and Arizona have a wage-withholding reciprocity agreement. A W-2 employee who lives in one state and works in the other is generally taxed only by the resident state on those wages, not both, though the agreement typically covers wage income only and does not extend to business or investment income.
Community Property Transition
Indiana uses common law marital property rules and Arizona is a community property state. Property acquired during marriage after the move may be characterized differently going forward, which matters for estate planning and for basis step-up on a spouse's death.
Beyond Income Tax
Indiana
Capital gains: No preferential rate. Capital gains are taxed as ordinary income at the flat state rate plus the applicable county rate.
Estate or inheritance tax: Indiana has no state estate tax and no inheritance tax; Indiana repealed its inheritance tax effective 2013. Only the federal estate tax, with its roughly $15 million per-person exemption in 2026, can apply to an Indiana decedent's estate.
Property tax: Indiana's average effective property tax rate is around 0.8% of home value, among the lower rates in the Midwest. The Homestead Standard Deduction reduces assessed value by the lesser of $48,000 or 60% of assessed value for an owner-occupied principal residence, with an additional supplemental deduction on the remaining value; county auditors are directed to develop procedures specifically to catch owners whose actual principal residence is outside Indiana.
Sales tax: Indiana has a flat statewide 7% sales tax, sometimes called the Gross Retail Tax, with no additional local sales tax layered on top anywhere in the state.
Arizona
Capital gains: Taxed as ordinary income at the flat 2.5% rate, but Arizona allows a 25% subtraction on qualifying net long-term capital gains (ARS §43-1022), which brings the effective rate on those gains down to about 1.875%. As of January 1, 2026 the subtraction applies to all qualifying long-term gains, not just assets acquired after 2011. Short-term gains get no subtraction and are taxed at the full 2.5%.
Estate or inheritance tax: None. Arizona has no estate tax and no inheritance tax.
Property tax: Effective rate is among the lowest in the country, roughly 0.45% to 0.56% depending on county, with Maricopa County near the higher end. Arizona offers a Senior Property Valuation Protection option that freezes the assessed value for qualifying low-income seniors 65 and older, rather than a general homestead portability system.
Sales tax: 5.6% state transaction privilege tax base rate, with combined state-and-local rates commonly running 8% to 9% in metro Phoenix and up to about 11.2% in some jurisdictions.
Who This Move Applies To
Travel Nurses
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'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.
Professional Athletes
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
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.
Snowbirds, Long Visitors, and RVers
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
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.
Remote Workers
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 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.
Military
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
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.
Airline Crew
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.
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.
Tools for This Move
Indiana to Arizona FAQ
Does Indiana have a 183-day rule separate from domicile?+
Yes, and Indiana is explicit that the two are independent tests. Under IC 6-3-1-12 and 45 IAC 3.1-1-21, you're an Indiana resident if you're domiciled in Indiana, or separately, if you're not domiciled in Indiana but maintain a permanent Indiana residence and spend more than 183 days in the state during the year. Indiana's own guidance says the 183-day test is not itself a test for domicile, so you can fail one and still be caught by the other.
Does Arizona use the 183-day rule?+
Not exactly. Arizona's statutory presumption under ARS §43-104 kicks in after more than nine months, roughly 274 days, of aggregate presence in a tax year, not 183 days. Spending fewer than 274 days doesn't automatically make you a nonresident either; Arizona still looks at your domicile and intent.
If I move to Florida but keep voting absentee or in person in Indiana, does that hurt my case?+
Yes, directly. Indiana's domicile-abandonment rule under 45 IAC 3.1-1-22.5 presumes you haven't given up Indiana domicile if you keep a permanent Indiana residence and continue voting in Indiana, among other listed factors. Re-registering to vote in your new state, and actually voting there, is one of the more concrete steps that supports a genuine domicile change.
How many months can I spend in Arizona as a snowbird before I owe Arizona income tax?+
Arizona's own presumption threshold is more than nine months (about 274 days) in the state during the tax year. Under that, you're not automatically presumed an Arizona resident, but your home state's own rules, for example California's nine-month presumption running the other direction, may still treat you as a resident there regardless of your Arizona day count.
Will keeping the homestead deduction on my Indiana house hurt me if I claim I moved to Florida?+
Yes. Indiana law specifically directs the Department of Local Government Finance and county auditors to develop procedures to identify homestead deduction claimants whose actual principal residence is outside Indiana, so continuing to claim it while filing as a nonresident elsewhere is exactly the kind of contradiction those procedures are built to catch. If you've genuinely moved, notifying your county auditor to remove the deduction is one of the concrete steps supporting your new domicile.
Do I have to pay Arizona tax on my California retirement income if I move to Arizona?+
Yes, once you're an Arizona resident, your 401(k), IRA, and pension distributions are taxed at Arizona's flat 2.5% rate regardless of where the money was earned or which state's employer originally sponsored the plan. Only Social Security and Arizona-recognized military retirement are exempt.
How does Indiana's county income tax work if I move counties or move out of state mid-year?+
On top of the flat 2.95% state rate, every Indiana county levies its own income tax, ranging roughly from 0.5% to over 3%, and your county rate generally depends on your county of residence. When you move into or out of Indiana mid-year, Form IT-40PNR handles both the state and county allocation for the split year, which makes Indiana's exit-year filing meaningfully more involved than a state with a single flat rate and no local layer.
What's Arizona's income tax rate?+
A flat 2.5% on all taxable income, with no brackets. It's one of the lowest state income tax rates in the country among states that tax income at all.
I live in Kentucky and work in Indiana. Do I owe Indiana income tax on my wages?+
No, not on wages. Indiana has reciprocity agreements with Kentucky, Michigan, Ohio, Pennsylvania, and Wisconsin, so a Kentucky resident's wages earned working in Indiana are taxed only by Kentucky, not Indiana, and Indiana withholding should not apply. Reciprocity covers wage income only; investment, rental, and business income from Indiana sources are still taxable by Indiana.
Does Arizona tax Social Security?+
No. Arizona fully exempts Social Security benefits from state income tax, regardless of your total income level.
Does Indiana tax my Social Security or pension after I retire?+
Social Security is fully exempt from both Indiana state and county tax. Pension, 401(k), and IRA distributions are taxed as ordinary income at the flat state rate plus your county's local rate, since Indiana doesn't offer the kind of broad age-based retirement income exclusion that Illinois or Michigan provide, aside from a modest deduction for certain military and railroad retirement income.
Does Arizona have a capital gains tax?+
Arizona taxes capital gains as ordinary income at the flat 2.5% rate, but allows a 25% subtraction on qualifying long-term gains, which brings the effective rate on those gains down to roughly 1.875%. Short-term gains get no subtraction.

Moving the other direction is a different fact pattern, not a mirror image: exit risk and establishment mechanics both flip.
