Arizona vs. California: Taxes, Cost of Living, and Housing

by Jeff Hernandez

Author: Jeff Hernandez | Arizona Realtor® & Attorney | The Connie Colla Group at RETSY

Arizona costs less to live in than California for most households, and taxes explain much of the gap: a flat 2.5% income tax, an effective property tax rate roughly a third lower, and home prices hundreds of thousands of dollars below California's coastal markets. The savings are not uniform, though. Sales tax is close, insurance does not automatically get cheaper, and a California home sale carries tax consequences that follow the seller across the state line.

How Do Arizona and California Income Taxes Compare?

Arizona taxes all income at a flat 2.5%, while California's graduated rates climb from 1% to 13.3% on taxable income above $1 million. Arizona's rate is the lowest flat income tax in the country, and Arizona does not tax Social Security benefits.

California's brackets rise quickly; the 9.3% rate begins around $145,000 of taxable income for joint filers. Wage earners also pay State Disability Insurance at 1.3% of all wages in 2026, with no cap. On $400,000 of taxable income, the annual difference between the two states can run well into five figures, depending on filing status, deductions, and how the income is earned.

How Do Property Taxes Compare Under Prop 13 and Prop 117?

Arizona's effective property tax rate averages about 0.48% of home value, compared with about 0.70% in California, according to the Tax Foundation. Both states also cap how fast taxable value can rise, a detail most comparisons miss.

California's Proposition 13 limits the base rate to 1% of assessed value and annual assessment growth to 2%, but resets the assessment to the purchase price at sale. A new buyer often pays several times what a longtime neighbor pays on a similar house, which is one reason many California owners hesitate to sell.

Arizona's Proposition 117, approved in 2012, means a home's Limited Property Value, the figure used to calculate the tax bill, cannot rise more than 5% a year. Bills can still rise when voters approve bonds or overrides, and the protection resets with a new purchase. For a seller with a decades-old Prop 13 basis, the fair comparison is Arizona's rate on the new purchase price against California's 1%-plus rate on a similar California purchase.

Is Sales Tax Really Lower in Arizona?

Only slightly. The Tax Foundation's 2026 figures put Arizona's average combined state and local rate at about 8.5%, against roughly 9% in California. California's 7.25% state rate is the highest in the country, but Arizona's cities and counties add more on top of a 5.6% state rate, so the combined numbers land close together.

How Much Less Do Homes Cost in Arizona Than in California?

A median-priced home in Phoenix costs less than half of one in Los Angeles, and even Scottsdale, the Valley's premium market, sells below the median in Los Angeles, Orange County, San Jose, and San Francisco. Redfin's figures for the three months ending September 2026, all home types:

Market	Median Sale Price	Change From Prior Year
Phoenix	$452,285	Up 0.5%
Scottsdale	$890,000	Up 9.2%
Los Angeles	$1,032,508	Down 1.7%
Orange County	$1,207,298	Up 0.6%
San Jose	$1,349,357	Down 5.0%
San Francisco	$1,579,248	Up 14.9%

Medians compress a wide range. Scottsdale runs from Old Town condominiums to North Scottsdale estates well above $2 million, and Phoenix includes Arcadia alongside far more modest neighborhoods. Supply drives the gap: California's coastal metros have underbuilt for decades, while the Phoenix Valley has had room to grow. For a closer look, see Phoenix vs. Scottsdale.

What Do California Relocators Most Often Overlook?

Three issues surprise California movers more often than the tax rates do.

California's Franchise Tax Board treats residency as a question of fact, not paperwork, and the taxpayer carries the burden of proving the move. A move timed close to a large income event, such as a business sale, is a common audit trigger, and keeping a California home or spending long stretches in the state can weigh against a claimed change.

Leaving also does not take a California home sale out of California's reach. Gain on California real estate is California-source income, and buyers generally must withhold 3 1/3% of the sales price at closing unless an exemption applies, as it does for many principal residence sales.

Insurance runs against expectations. California's FAIR Plan, the insurer of last resort, raised rates an average of 29.1% for policies renewing on or after October 15, 2026. Yet some national surveys put Arizona's average premium above California's, where rates are tightly regulated. The real difference is usually availability, not price, so quote insurance early in escrow.

Which State Makes More Financial Sense for Your Household?

Arizona usually comes out ahead for high earners, retirees drawing Social Security, and owners bringing equity out of a California sale, but the answer depends on your numbers, not any single rate. Put income, the home you would buy, insurance quotes, and the tax on your California sale side by side, and involve a CPA early if a large income event is near.

Frequently Asked Questions

Is it cheaper to live in Arizona than in California?

For most households, yes. Arizona combines a flat 2.5% income tax, a lower effective property tax rate, and home prices well below California's major metros; Phoenix's median sale price was about $452,000 in the three months ending September 2026, against roughly $1 million in Los Angeles. Sales tax is close, and insurance is not always cheaper, so savings depend on income and the home you buy.

Does Arizona have a state income tax?

Yes. Arizona has a flat 2.5% income tax that applies at the same rate to all taxable income, the lowest flat rate in the country. Arizona cities do not add a local income tax, and the state does not tax Social Security benefits. That structure favors retirees and high earners leaving California, where the top marginal rate reaches 13.3% on taxable income above $1 million.

Does Arizona have a property tax cap like California's Prop 13?

Yes, though it works differently. Under Proposition 117, a home's Limited Property Value, the figure used to calculate the tax bill, cannot rise more than 5% a year. California's Prop 13 caps assessment growth at 2% and the base rate at 1%. In both states the protection resets when a home sells. Arizona's average effective rate, about 0.48%, is lower than California's, about 0.70%.

Do I owe California tax if I sell my California home after moving to Arizona?

Possibly. Gain on California real estate is California-source income, so California can tax it even after you become an Arizona resident. Buyers generally must withhold 3 1/3% of the sales price at closing unless an exemption applies, and many principal residence sales qualify. Because timing, residency, and the federal home-sale exclusion interact, have a CPA familiar with both states review the sale before closing.
