Moving to Arizona: City Guides, Checklist & Tips
Updated July 2026
Arizona charges a flat 2.5% state income tax — the lowest flat rate of any state that taxes income — a significant draw for the roughly 52,000 Californians who moved to Arizona in a recent year, more than double the number who moved the other way. Phoenix, the fifth-largest city in the country at 1.6 million residents (nearly 5 million in the metro), anchors that growth with a cost of living index of just 107 — 7% above the national average — a median home price of $415,000, and an economy that has diversified well past retirement and real estate into a rapidly expanding semiconductor corridor led by TSMC and Intel. The trade for 299 days of annual sunshine is real heat: average July highs of 106°F, with 110°F-plus days routine from mid-June through mid-September. This hub collects our relocation guide for Phoenix, plus the practical steps to become a resident.

How Arizona Got Its Name
Arizona's name most likely comes from Arizonac, a Spanish rendering of an O'odham word meaning "place of the small spring," first applied to a spot near a 1730s silver strike in what is now Sonora, Mexico. Spanish colonists then extended the name north as they mapped the territory, and Congress adopted it when Arizona became a state in 1912 — the last of the contiguous 48. A quieter irony sits inside that origin story: a name that started with a modest desert spring now belongs to a state whose defining natural landmark, the Grand Canyon, holds essentially none — the canyon's water is the Colorado River, a mile below the rim. Arizona's other defining trait is engineered comfort in extreme heat: Phoenix's Sky Harbor-adjacent metro grew up around air conditioning, and the state didn't reach a population of one million until refrigerated cooling made its summers survivable at scale.
How to Become a Arizona Resident
Establishing residency unlocks a Arizona driver's license, vehicle registration, in-state tuition, and resident access to state parks and programs. You establish residency in Arizona by doing any one of the following — you don't need all of them:
- Renting or buying a house or apartment in Arizona
- Being employed within Arizona (except seasonal agricultural work)
- Being registered to vote in Arizona
- Having a business located in Arizona
- Having children who attend an Arizona primary or secondary school
- Staying in Arizona seven months or more in a calendar year
Arizona Moving Checklist

- Register to vote at your new address
- Update your health insurance and other policies, and find new providers
- Transfer medical, dental, and school records, and research district or charter school options carefully
- License your pets and find a local veterinarian
- Set up utilities — Phoenix is split between APS and SRP for electric service — and file your change of address with USPS
- Review the tax picture: Arizona's flat 2.5% income tax is the lowest flat rate in the country
Questions Movers Ask About Arizona
Does Arizona have an income tax?
Yes, but at the lowest flat rate of any state that taxes income: 2.5% on all income, with no brackets. Sales tax adds 5.6% at the state level, commonly reaching 8–9% once city and county taxes are combined — a real factor for high earners moving from a state like California, which taxes income up to 13.3%.
How expensive is it to live in Arizona?
Arizona runs close to the national average — a statewide cost of living index of about 106–107, meaning daily expenses are roughly 6–7% above the U.S. norm. Phoenix's median home price is $415,000 to $460,000 depending on the source, well below comparable Sun Belt metros like San Diego or Miami.
How long do I have to get an Arizona driver's license after moving?
Arizona doesn't publish a single fixed grace period for new residents the way many states do — the state's own guidance describes updating your license and registration promptly after you establish residency, and most practical guidance points to about 30 days. Arizona defines residency itself as staying in the state seven months or more in a calendar year, or working there.
How hot does it get in Phoenix?
Very hot. Average July highs reach 106°F, and temperatures of 110–115°F occur multiple times most summers between mid-June and mid-September. The trade-off is winter: highs consistently run 65–75°F from November through March, which is why Phoenix draws so many seasonal residents.
How many national parks does Arizona have?
Three: Grand Canyon, Saguaro, and Petrified Forest. The Grand Canyon alone draws millions of visitors a year and is reachable from Phoenix in about 3.5 hours.
Which Arizona city should I move to?
Phoenix is the practical answer for most movers — the state's capital, its largest job market, and the center of its semiconductor and tech growth. Tucson, home to the University of Arizona, is smaller, more affordable, and has a distinct Sonoran Desert character that some residents find more authentic than Phoenix's suburban sprawl, though it doesn't yet have a dedicated ScoutLocale guide.
