Residency rules, sticky taxes, and first-year steps (2026)
2026.1 Edition · Revised 2026-07-25 · DomusDay Research
The move changes the rate; the record decides whether it sticks. Minnesota keeps taxing until domicile actually changes, and its 183-day statutory test stays live while any Minnesota abode is maintained. Below: what follows leavers, and the Arizona steps that build the record.
Arizona taxes all income at a flat 2.5% — no brackets — and subtracts 25% of net long-term capital gains on assets acquired after 2011, putting the effective long-term rate under 1.9%.
Source ↗More than nine months in the state during a taxable year creates a rebuttable presumption of Arizona residency. For arrivals it works in your favor: the presumption and dated records anchor the part-year split.
Source ↗Arizona's homestead exemption — a $400,000 base, inflation-adjusted annually — attaches to the primary residence with no filing or recording required, unlike the declaration states.
Source ↗Arizona is the easy half. Minnesota decides whether the move counts, and it decides on evidence — the two tests below stay live until the record closes them out.

Top-bracket rates differ by 7.35%: Minnesota at 9.85%, Arizona at 2.5% — an illustration at the top marginal rate, not an effective-rate calculation.
The first weeks in Arizona matter more than they look: each step below produces a dated document, and dated documents are what answer a Minnesota examiner years later. Do them early and the record starts on your side of the timeline.
Arizona treats you as a resident for licensing once any trigger applies — seven months' presence in a calendar year, Arizona employment, voter registration, or children enrolled without nonresident tuition — and a license and registration follow.
Source ↗Vehicles are registered on becoming an Arizona resident, with Arizona liability insurance required; emissions testing applies in the Phoenix and Tucson areas.
Source ↗Voter registration requires Arizona and county residency; registration closes 29 days before an election and is available online through the MVD system.
Source ↗The Department of Revenue's residency procedure weighs vehicle registration, voter registration, property ownership, and a consistent permanent address — the same records the steps above generate.
Source ↗Arizona's homestead exemption — a $400,000 base, inflation-adjusted annually since 2024 — attaches to the primary residence automatically, with no filing required.
Source ↗Every vehicle operated on Arizona roads must carry Arizona liability insurance.
Source ↗Arizona is a community property state: property acquired by either spouse during the marriage is community property, with gift and inheritance exceptions — relevant to title, basis, and estate planning on arrival.
Source ↗The arrival year is filed on Form 140PY, the part-year resident return, splitting income at the residency change date.

Every rule on this page traces to a statute, regulation, or agency publication, listed in full on each state's own plate.
Rule 8001.0300's lettered list of considerations — prior domicile, voter registration, employment, new and former living quarters, homestead status, driver's license, vehicle location, resident hunting and fishing licenses, tax filing status, worship and club membership, mailing address, percentage of time present, schools and tuition, and statements to insurers, among others. No single factor controls. The list was long cited as 26 factors; after statute excluded bank-account and adviser location, the current lettered list runs A to Y.
The Department of Revenue opens with a letter and a Residency Questionnaire, with 30 days to gather supporting documentation — planners, calendars, plane tickets, canceled checks, credit card statements, and receipts are the record types its guidance names. Assessments generally run 3½ years back, extended to 6½ for large omissions and unlimited where no return was filed.
