Retirement in Arizona: Taxes and Cost of Living

Arizona is not a no-income-tax state, but its flat 2.5% rate is one of the lowest in the country, and Social Security is fully exempt. Combine that with warm winters and a near-average cost of living, and it remains one of the most popular places to retire. Here is the full tax picture.

Arizona retirement tax rules

Arizona levies a flat 2.5% income tax, which it phased down to that rate in recent years (Arizona Department of Revenue). That single rate applies to 401(k) withdrawals, IRA distributions, and most pension income. Because the rate is so low, the actual tax on retirement income is small compared with high-tax states. On $50,000 of taxable withdrawals, the state tax is about $1,250.

Social Security benefits are fully exempt from Arizona income tax, and so is military retirement pay, which Arizona stopped taxing entirely in 2021. Certain federal, Arizona state, and local government pensions qualify for an exemption of up to $2,500 per year. There is no state estate tax and no inheritance tax, which keeps legacy planning simple.

The net effect is that Arizona behaves much like a low-tax state for retirees, even though it is not one of the nine with no income tax at all. A retiree living mostly on Social Security and modest withdrawals may owe very little to the state.

Cost of living in Arizona

Arizona's cost of living index is approximately 103, just above the national average of 100 (MERIC). The spread within the state is meaningful. Scottsdale and the more affluent parts of metro Phoenix run well above average, while Tucson, the West Valley retirement communities, and smaller towns sit at or below it.

For retirees, the desert climate adds a couple of line items worth planning for: summer cooling costs and water. Housing remains the biggest variable, and the difference between a Scottsdale address and a Sun City or Green Valley one is large. The combination of low income tax and an exempt Social Security benefit means more of your gross income stays in your pocket than in most states, which helps offset Arizona's slightly above-average cost of living.

Does Arizona tax retirement income?

Partly. Arizona taxes most retirement income at its flat 2.5% rate but exempts Social Security entirely. Here is how the four most common sources are treated.

Income type Taxed in Arizona? Details
401(k) / IRA withdrawals Yes Taxed at the flat 2.5% rate. Federal tax also applies.
Pension income Yes Taxed at 2.5%. Up to $2,500 of certain government pensions is exempt.
Social Security benefits No Fully exempt from Arizona income tax.
Capital gains Yes Taxed as income at 2.5%. Federal rules also apply.

Use the retirement tax calculator to estimate the federal tax on your withdrawals and benefits, then add Arizona's 2.5% on the taxable portion.

Best places to retire in Arizona

Scottsdale

Scottsdale is Arizona's upscale retirement address, with golf, spas, dining, and top-tier healthcare including the Mayo Clinic campus. It carries an above-average cost of living, but for retirees who want resort-style amenities and excellent medical care in one place, it is the premier choice in the Phoenix metro.

Tucson

Tucson offers a lower cost of living than Phoenix, a vibrant arts and university scene, and slightly milder summers thanks to its higher elevation. The University of Arizona anchors strong healthcare, and the surrounding desert and mountains appeal to active retirees.

Prescott

At roughly 5,400 feet, Prescott trades the desert heat for four mild seasons, pine forests, and a historic small-town square. It is a popular choice for retirees who love Arizona's lifestyle but want cooler summers, with regional healthcare in town and Phoenix about 90 minutes away.

Sun City and Surprise

In the West Valley, Sun City was one of the original master-planned active-adult communities and remains a value-focused option, alongside the growing city of Surprise. Both offer recreation built for retirees, lower housing costs than the east side of the metro, and easy access to Phoenix services.

Green Valley

South of Tucson, Green Valley is a long-established retirement community with an affordable cost of living, abundant recreation, and a quiet pace. It suits retirees who want desert living without big-city prices, with Tucson's hospitals a short drive north.

Arizona pension system

The Arizona State Retirement System (ASRS) covers state employees, public school staff, and many county and municipal workers. It pays a defined-benefit pension based on years of service and final average salary. Police officers and firefighters are covered separately by the Public Safety Personnel Retirement System. ASRS pension income is taxed at Arizona's flat 2.5% rate, though up to $2,500 of certain government pension income is exempt.

If you have a pension, our pension calculator estimates your monthly benefit from years of service, and can compare a lump sum against monthly payments if your plan offers a choice.

Partly. Arizona has a flat 2.5% income tax that applies to 401(k) withdrawals, IRA distributions, and most pension income. Social Security benefits are fully exempt. At 2.5%, Arizona has one of the lowest flat income tax rates in the country, so the tax on retirement income is modest compared with most states that tax it at all.
Does Arizona tax Social Security benefits?
No. Arizona fully exempts Social Security benefits from state income tax. Your benefits may still be federally taxable depending on your combined income, but Arizona itself does not tax them.

For many retirees, yes. The 2.5% flat tax is low, Social Security is exempt, there is no estate or inheritance tax, and the warm, dry climate is a long-standing draw. Cost of living is near the national average, with Phoenix-area suburbs and Tucson generally more affordable than Scottsdale. Summer heat is the main lifestyle trade-off.
