Do You Pay State Income Tax in Arizona?

Short answer: yes, Arizona has a state income tax, but it's remarkably low. Arizona charges a flat 2.5% rate on all taxable income, one of the lowest flat rates of any state that taxes income, and there is no city or county income tax anywhere in the state on top of it. Social Security benefits aren't taxed at all. For anyone relocating from a high-tax state, and especially from California, the difference can be dramatic.

This is one of the first questions I hear from buyers moving to North Scottsdale, and it's a good one, because state income tax is often one of the biggest financial reasons people make the move in the first place. Here's exactly how Arizona's income tax works and what it means for your bottom line.

How Arizona's Income Tax Works

Arizona uses a flat tax, which keeps things simple. Every resident pays the same 2.5% rate on taxable income, no matter how much they earn, and the rate is identical for single filers, married couples filing jointly or separately, and heads of household.

This is a relatively recent change. Arizona moved to the flat 2.5% rate in 2023, following a voter-approved constitutional amendment, replacing an older graduated system that topped out at 4.5%. It was one of the most aggressive state income tax cuts in recent U.S. history, and it placed Arizona among the most tax-competitive states in the country.

Just as important is what sits on top of it: nothing. No Arizona city or county, including Scottsdale, Phoenix, Mesa, or Tempe, levies its own personal income tax. That flat 2.5% is the entire state and local income tax picture.

What That Looks Like in Real Dollars

Because the rate applies to taxable income (your income after deductions, including a standard deduction that mirrors the federal amount), the effective bite is even smaller than 2.5% of your gross.

A few illustrations:

• A single filer with $100,000 in income pays roughly $2,125 in Arizona state income tax
• A filer with $250,000 in income pays roughly $5,900
• A household with $500,000 in taxable income pays roughly $12,500

Now put that last one in perspective.

Arizona vs. California: The Comparison That Moves People

This is where relocating buyers really feel it. California uses a steeply progressive income tax with rates that climb to 13.3% at the top, among the highest in the nation. Arizona's flat 2.5% is a fraction of that.

Take that household with $500,000 in taxable income. In Arizona, the state income tax is roughly $12,500. In California, that same household could face a state tax bill several times higher, because California's marginal rates in that income range run far above Arizona's flat rate. For high earners, business owners, and investors, the annual savings from that gap alone can run into the tens of thousands of dollars, year after year. It's a major reason so many of my clients are relocating from California to North Scottsdale.

Great News for Retirees

Arizona is also a friendly state for retirement income:

• Social Security is fully exempt. Arizona does not tax Social Security benefits at all.
• Military retirement pay is fully exempt, which makes the state popular with military retirees.
• Traditional pensions, 401(k), and IRA withdrawals are taxed at the flat 2.5%. There's also a subtraction available for certain government pensions.
• No estate tax and no inheritance tax. Arizona levies neither.

As an example, a retired couple drawing $80,000 a year, with $35,000 from Social Security and $45,000 from IRA withdrawals, would owe Arizona income tax only on the $45,000, for a state tax bill of roughly $1,125.

The Full Tax Picture

To be complete and fair, low income tax doesn't mean no taxes. Arizona does have a sales tax, known as the Transaction Privilege Tax, and combined rates can be on the higher side depending on the city. But the two costs that most affect homeowners and high earners, income tax and property tax, are both notably low here. Arizona's effective property tax rate is among the lowest in the country, which pairs with the low income tax to create a genuinely light overall burden for most residents.
