Most of the calls we get from California, New York, and Illinois start the same way: "We love the house, but what's this actually going to cost us?" The honest answer is that the sale price on a Scottsdale listing is often the smaller number. The bigger one is what a buyer stops paying every year once they establish Arizona residency.

We're not tax advisors, and nothing here should replace a conversation with your CPA or estate attorney before you make a residency decision. But we talk to relocating buyers about the broad strokes constantly, and the numbers are worth laying out plainly, because they're a real part of why Scottsdale, Paradise Valley, and the rest of our market keep pulling buyers from higher-tax states.

The headline number: a flat 2.5% state income tax

Arizona taxes income at a flat 2.5%, the lowest rate of any state that still levies an income tax. It's been phased down from 4.5% over the last several years and landed at 2.5% for everyone, regardless of income level. There are no brackets to climb and no surprise jump once your income crosses a threshold.

Compare that to where a lot of our relocating buyers are coming from:

StateTop marginal income tax rateStructure
Arizona2.5%Flat, no brackets
California13.3%Progressive, tops out above $1M
New York (state)10.9%Progressive, tops out above $25M
New York City (add-on)+3.876%City resident tax on top of state
Illinois4.95%Flat, but the highest flat rate in the country

For a household earning $750,000 a year, the gap between California's top rate and Arizona's flat rate alone can run into the tens of thousands of dollars annually. For NYC residents, stacking the state and city rate on top of each other makes the math even starker. None of that requires a tax attorney to appreciate. It's just arithmetic that compounds every year you own the home.

What actually changes at closing

Establishing Arizona residency doesn't erase every tax obligation from your prior state, especially if you keep income sources or property there. But for buyers who are genuinely relocating, not just adding a second home, the income tax exposure on future earnings shifts to Arizona's flat rate going forward.

Property taxes: the gap most buyers underestimate

Income tax gets the headlines, but property tax is the line item that shows up on every single year's bill regardless of income, and it's where the Scottsdale math looks especially good against coastal California.

  • Scottsdale runs low even by Arizona standards. Effective property tax rates in Scottsdale ZIP codes generally fall in the 0.4% to 0.5% range of assessed value, below both the Arizona state median and well below the national median of roughly 1%.
  • California's effective rate looks similar on paper but isn't in practice. California's statutory cap is 1% of assessed value, but that assessment resets to full market value at the time of purchase. A buyer moving into a $3M California home is taxed on $3M from day one, while a longtime owner down the street might still be taxed on a fraction of that under Prop 13 protections.
  • The dollar gap is real, not theoretical. On a comparably priced multimillion-dollar home, a new California buyer can end up paying two to three times the annual property tax bill of a new Scottsdale buyer, purely because of how the assessed base and rate interact.

That gap holds every year you own the home, not just at closing, which is why it tends to matter more to buyers over a five- or ten-year horizon than the headline sale price does.

No estate tax, no inheritance tax

Arizona levies neither an estate tax nor an inheritance tax, and Social Security income is exempt from state taxation. For buyers thinking about multi-generational wealth transfer, that matters alongside the annual income and property tax picture, particularly for households coming from states like New York that maintain their own estate tax regimes separate from the federal one.

Capital gains: a meaningful break for long-term holders

Arizona taxes capital gains as ordinary income at that same flat 2.5% rate, but as of January 2026, the state allows a 25% subtraction on net long-term capital gains, and that subtraction now applies to all qualifying assets regardless of when they were acquired. In practice, that brings the effective state rate on long-term gains down to roughly 1.875%. For a buyer selling appreciated stock, a business, or another property to fund a Scottsdale purchase, that's a meaningfully lighter state tax hit than what California's top-bracket treatment of capital gains as ordinary income would produce.

What this looks like for an actual relocation

We're careful not to promise clients a specific dollar figure, because every household's income mix, filing status, and prior-state obligations are different. But the pattern we see across relocating buyers is consistent:

  • The income tax gap is the single biggest lever. It scales directly with income, so it matters most to the highest earners, which happens to describe most buyers shopping above $2M in this market.
  • The property tax gap is the most predictable annual savings. It doesn't depend on income at all, just on the home's value and the rate differential, which makes it easier to estimate up front.
  • The estate and capital gains treatment matters most at specific life moments, like a liquidity event, a business sale, or estate planning, rather than showing up on a monthly budget.

None of this means Arizona is automatically the right move for every household, and we always tell clients to run their specific numbers with a CPA licensed in both states before treating any of this as decided. But when a buyer asks us why so many California, New York, and Illinois transplants end up here rather than in another Sun Belt market, the tax structure is a real part of the honest answer, alongside the weather, the golf, and the fact that $3M still buys a serious home in Scottsdale.

If you're weighing a move and want to talk through what your specific situation might look like on the Arizona side, we're happy to have that conversation, and to point you toward tax and estate professionals who can run the numbers properly.
