Moving to Arizona from California? Your first official to-do is the Arizona MVD. ADOT says you must register your vehicle as soon as you become an Arizona resident, and residency starts when any of several triggers apply, such as working in Arizona or staying seven months or more in a calendar year. Bring your California title, registration and driver license; no appointment is needed.
The biggest money difference is how property taxes work. California's Prop 13 resets a home's base value when it sells. In Arizona, the limited property value used for taxes generally grows no more than 5% a year, and a sale doesn't automatically reset it.
Data note: MVD rules come from ADOT's "New to AZ" page (checked Oct. 29, 2026). Arizona valuation rules come from A.R.S. 42-13301 and 42-13302; California rules come from the California State Board of Equalization's Publication 29. Income tax is not covered here; talk to a tax professional about your move.
When Do You Become an Arizona Resident?
Per ADOT MVD, you're considered a resident if any of these apply:
- You stay in Arizona seven months or more in a calendar year
- You work in Arizona (except seasonal agricultural work)
- You're registered to vote in Arizona
- You place children in school without paying nonresident tuition
- You have a business with an Arizona office that bases and operates vehicles here
- You get a state license or pay resident tuition
- Your business operates vehicles transporting goods or passengers within Arizona
Your Arizona MVD Checklist
Driver License or ID
Bring:
- Proof of authorized presence in the U.S.
- Your current California driver license or ID
- Your Social Security number
Want a Travel ID? It's optional, and you'll need two documents showing your Arizona address, such as a utility bill, bank statement or insurance policy.
Vehicle Registration
- Register as soon as you become a resident
- Bring your California title and current registration for each vehicle
- Check whether you need an emissions test first; ADOT says some vehicles in the Phoenix metro and Tucson areas need one before registration

Arizona vs. California Property Tax: How the Systems Differ
California (Proposition 13)
According to the California State Board of Equalization:
- The base property tax rate is 1% plus rates for voter-approved debt
- Property is reassessed to market value on a change in ownership or new construction, creating a base year value
- Annual increases in base year value are generally limited to 2%
Arizona
- Your notice shows a full cash value and a limited property value (LPV); taxes are calculated on the LPV
- Under A.R.S. 42-13301, LPV is generally the prior year's LPV plus 5%, and it can't exceed full cash value
- Under A.R.S. 42-13302, a change in the occupant of a single-family home is not, by itself, a change in use, so a sale alone doesn't reset LPV
What it means for you: Long-time California owners often carry low Prop 13 bases. In Arizona, ask for the seller's actual tax bill for any home you consider; that's a good preview of yours. For primary-residence tax breaks, see our Arizona homestead exemption guide.

“When clients relocate from California, I ask early about timing, because the MVD, school enrollment and a closing date all have to line up. The best moves start with a short list of neighborhoods and a clear picture of property taxes, so there are no surprises after the keys change hands.”
