Arizona State Income Tax: A Relocation Guide for Scottsdale Buyers

For a lot of people moving to North Scottsdale, taxes aren't a footnote, they're the whole reason the move pencils out. So let's answer the question head-on: does Arizona have a state income tax? Yes, but it's one of the lightest in the nation, a single flat rate of 2.5% on taxable income, with no additional city or county income tax layered on top and no tax on Social Security. If you're relocating from a high-tax state, California in particular, the contrast can be striking.

I field this question constantly from buyers eyeing a move, and for good reason. Here's a clear look at how Arizona's income tax actually works and what it could mean for your finances.

A Simple, Flat System

Arizona keeps its income tax refreshingly straightforward with a flat structure. Everyone pays the same 2.5% on their taxable income, regardless of earnings, and the rate doesn't change whether you file as a single person, a married couple filing jointly or separately, or a head of household.

That flat rate is fairly new. Arizona adopted it in 2023 after voters approved a constitutional amendment, sweeping away an older tiered system that had reached as high as 4.5%. It ranked among the boldest state income tax reductions the country has seen in years, and it vaulted Arizona into the ranks of the most tax-friendly states around.

And here's the part that surprises newcomers: nothing stacks on top of it. Not a single Arizona city or county, Scottsdale, Phoenix, Mesa, Tempe, or otherwise, imposes its own personal income tax. That 2.5% is the whole story on state and local income tax.

Putting Real Numbers to It

Since the rate hits your taxable income, meaning what's left after deductions like the standard deduction that tracks the federal figure, the true impact is even lighter than a straight 2.5% of your paycheck.

Consider a few scenarios:

• Earn $100,000 and file single? Your Arizona income tax runs about $2,125
• At $250,000, expect roughly $5,900
• A household with $500,000 in taxable income owes around $12,500

That final figure is where the comparison gets interesting.

Why Californians Feel It Most

Here's where relocating buyers really notice the difference. California runs a sharply progressive income tax topping out at 13.3%, one of the steepest in the country. Set that beside Arizona's flat 2.5% and the gap is enormous.

Go back to that $500,000 household. Arizona would tax it around $12,500 at the state level. In California, the bill could be several times larger, because the state's marginal rates at that income level sit well above Arizona's flat rate. For high earners, entrepreneurs, and investors, that single difference can free up tens of thousands of dollars annually, and it keeps repeating year after year. It's one of the leading reasons my clients are trading California for North Scottsdale.

A Friendly Landscape for Retirees

Retirement income gets favorable treatment in Arizona too:

• Social Security is entirely exempt. The state taxes none of it.
• Military retirement pay is fully exempt as well, a big draw for military retirees.
• Pensions, 401(k)s, and IRA withdrawals face the flat 2.5%, with a subtraction available for certain government pensions.
• There's no estate tax and no inheritance tax in Arizona.

Picture a retired couple pulling in $80,000 a year, split between $35,000 in Social Security and $45,000 in IRA withdrawals. Arizona would tax only the $45,000, leaving a state tax bill of about $1,125.

Seeing the Whole Picture

In fairness, a low income tax doesn't add up to a tax-free life. Arizona does levy a sales tax, called the Transaction Privilege Tax, and combined rates can run a bit high depending on the city. But the two taxes that hit homeowners and higher earners hardest, income and property, are both low here. Arizona's effective property tax rate is among the nation's lowest, and together with the modest income tax, it produces a genuinely light overall load for most residents.
