Why Are So Many People Moving to Arizona From California?
Arizona gained 55,200 residents through domestic migration in 2024, the fourth-highest net gain of any state in the country, according to U.S. Census Bureau data. Of the roughly 235,000 people who moved into Arizona from other states that year, 52,400 came from California alone, with Washington (17,600) and Texas and Colorado (10,300 each) rounding out the top sources. For many of these movers, especially high-net-worth households, the decision is driven as much by Arizona’s flat 2.5% income tax and lack of an estate tax as it is by climate or lifestyle.

If you’ve been watching the moving trucks head east out of California, or noticing how many new neighbors in Paradise Valley and Scottsdale seem to have Washington or Texas plates, you’re not imagining a trend. You’re watching one of the largest sustained wealth migrations in the country play out in real time, and Arizona is one of its primary destinations. For buyers at the $1M–$30M+ level, the calculation isn’t only about square footage or a mountain view. It’s about what a move actually does to your income tax bill, your estate, and your long-term cost of carrying a significant property. Here’s what the numbers show, and what they mean if you’re the one weighing the move.
The Migration Numbers: Where Arizona’s New Residents Are Coming From
Arizona’s population growth isn’t new, but the scale of it in recent years has been notable. According to the U.S. Census Bureau’s American Community Survey data compiled by USAFacts, Arizona’s 2024 net domestic migration gain of 55,200 ranked fourth nationally, trailing only a handful of other fast-growing states. The breakdown is worth sitting with:
- 235,000 people moved into Arizona from other U.S. states in 2024
- 179,300 people left Arizona for other states
- California was the single largest source of new Arizona residents, at 52,400
- Washington sent 17,600 new residents
- Texas and Colorado each sent 10,300
This isn’t a one-year blip. Earlier Census data covering 2017 through 2021, reported by FOX LA, found that roughly 184,000 Californians relocated to Arizona over that five-year span, meaning close to one in five people who moved into Arizona during that period came from California. Washington ranked as the second-largest historical source, contributing an estimated 50,000 movers over the same stretch. The pattern has held steady for close to a decade: Arizona, and Paradise Valley, Scottsdale, and Arcadia in particular, has become a primary landing spot for wealth leaving higher-tax, higher-cost coastal and Pacific Northwest markets.
What’s changed more recently is who is making the move. A decade ago, much of this migration was retirees and second-home buyers. Today, we’re seeing more primary-residence buyers in their peak earning years, business owners relocating their domicile along with their household, and families making the move permanent rather than seasonal. That shift shows up directly in the kind of properties we’re selling — year-round, full-time luxury residences, not just winter retreats.
The Tax Math: What Relocating to Arizona Actually Saves You
Here’s where the migration numbers connect directly to a decision you can model on a spreadsheet.
Arizona has a flat 2.5% state income tax, one of the lowest in the country among states that tax income at all. California, by contrast, has a top marginal rate of 13.3% on income above $1 million, with capital gains taxed as ordinary income. On $500,000 of annual income, that difference alone translates to roughly $10,000 to $20,000 a year in state tax savings, depending on your specific income mix and deductions. On the kind of income many of our Paradise Valley and Scottsdale buyers report, the annual savings can run considerably higher, year after year.
The comparison looks different depending on where you’re coming from, and it’s worth being precise about it:
- From California: The savings are almost entirely about income tax rate. At 13.3% versus 2.5%, this is the clearest and largest tax differential of any origin state.
- From Washington: Washington has historically had no state income tax, but that’s changing. The state legislature recently adopted a new income tax on high earners, with a 9.9% rate above a $1 million deduction, set to take effect for income earned starting in 2028. Washington also imposes a 7% capital gains excise tax on gains above roughly $270,000, and its estate tax now reaches rates as high as 20% on estates above a $3 million exemption. For Washington households with significant investment gains or estate planning concerns, the arithmetic is shifting quickly in Arizona’s favor.
- From Texas: Texas has no state income tax, so the savings story is less about income tax and more about overall cost of carrying a property and portfolio diversification, along with proximity and climate preferences that drive many Texas relocations.
- From Oregon: Oregon’s top income tax rate is 9.9%, and its estate tax exemption is just $1 million and isn’t adjusted for inflation, meaning a meaningful estate tax exposure for far more households than most people assume.
Then there’s the estate planning piece, which matters enormously at this price point and often gets less attention than the income tax headline. Arizona has no state estate tax and no inheritance tax. That stands in direct contrast to states like Washington and Oregon, where state-level estate taxes can apply well before the federal exemption threshold, and it means a Paradise Valley or Scottsdale estate passes to heirs without an additional state-level toll on top of federal considerations.
What Relocating Buyers Should Know Before Making the Move
Moving your residence is only half the equation. Moving your domicile — the legal state the IRS and your home state’s tax authority recognize as your true home — is what actually changes your tax picture. A few things we walk every relocating buyer through:
- Establishing Arizona domicile matters as much as the purchase. Simply owning a home here isn’t enough to shift your tax residency. Where you spend your time, where your driver’s license and voter registration are, and where your business interests are managed all factor into it. This is a conversation worth having with a tax attorney or CPA before, not after, you close.
- Property tax in Arizona is assessed differently than in many origin states. Arizona’s property tax structure and assessment process differ meaningfully from California’s Proposition 13 framework or Texas’s property tax rates, and it’s worth modeling your specific property before you buy, not after.
- Timing your sale and purchase matters for capital gains. If you’re selling a highly appreciated property in your current state to fund a Paradise Valley or Scottsdale purchase, the state where you’re a resident at the time of sale can significantly affect what you owe. This is exactly the kind of decision that benefits from coordinated planning between your real estate advisor and your tax professional well before you list.
- The right property matters as much as the right tax strategy. Paradise Valley, Scottsdale, and Arcadia each offer a different lifestyle and property profile, from large view-lot estates to walkable, architecturally significant homes. Your specific goals for the property, whether that’s a full-time residence, a part-time base, or a long-term hold, should shape where you look.
Every household’s situation is different, and the right sequencing of a sale, a domicile change, and a purchase depends on your specific numbers. That’s a conversation worth having early, not after you’ve already found the house.
Frequently Asked Questions
Why are so many Californians moving to Arizona?
The leading factors are Arizona’s much lower flat income tax rate (2.5% versus California’s top rate of 13.3%), a lower overall cost of living, and a desert climate many buyers prefer for full-time or part-time living. Census data shows California has been the single largest source of new Arizona residents for close to a decade, with 52,400 Californians moving to Arizona in 2024 alone.
Does Arizona have an estate tax or inheritance tax?
No. Arizona has no state-level estate tax and no inheritance tax, which means assets pass to heirs without an additional state tax beyond any federal estate tax that may apply. This is a meaningful consideration for high-net-worth households relocating from states like Washington or Oregon, both of which maintain state estate taxes.
How much can you actually save in taxes by moving from California to Arizona?
It depends on your income and how it’s structured, but on $500,000 of annual income, the difference between California’s 13.3% top rate and Arizona’s flat 2.5% rate works out to roughly $10,000 to $20,000 a year in state income tax alone. Households with significant capital gains or business income often see even larger differences, since California taxes capital gains as ordinary income.
Is Arizona still a good tax move if I’m coming from Texas, which has no income tax?
Texas residents won’t see income tax savings from a move to Arizona, since Texas doesn’t tax income either. For Texas-based relocators, the more relevant factors tend to be overall cost of living, property tax structure, climate preference, and proximity advantages, rather than a direct income tax comparison.
What should I do first if I’m planning to relocate to Arizona for tax purposes?
Before you buy, talk with a tax attorney or CPA about what it takes to establish Arizona domicile, since owning a home here alone doesn’t change your tax residency. From there, coordinating the timing of any sale in your current state with your Arizona purchase can meaningfully affect your overall tax outcome, which is a conversation we help every relocating client have early.
