Arizona taxes for early retirees: a flat tax and a dry heat

By Tom, CPA · Updated October 25, 2026

TL;DR: Arizona taxes most income at a flat 2.5% as of October 2026. Social Security is exempt, government pensions get a subtraction of up to $2,500, and military retirement pay is fully excluded. IRA withdrawals, Roth conversions and capital gains are taxed at the flat rate, which is low enough that many early retirees barely notice it.

Arizona's income tax used to have brackets. Now it has one rate, and it's low: 2.5%. For an early retiree pulling $50,000 a year of taxable income from IRAs and conversions, that's roughly a four-figure bill before state deductions, not the five-figure surprise some states deliver.

Add an exemption for Social Security, a small break for government pensions, and full exclusion of military retirement pay, and Arizona becomes one of the more retiree-friendly income tax states. Here's how it works.

Flat rate (verify)

According to the Arizona Department of Revenue's individual income tax highlights, Arizona uses a single flat rate of 2.5% on taxable income. As of October 2026, that rate applies to all filing statuses.

Arizona starts from federal adjusted gross income, then applies its own additions, subtractions and standard deduction. Income types that are generally taxable at the 2.5% rate include:

• Traditional IRA and 401(k) withdrawals
• Roth conversions
• Private pensions and annuities
• Interest, dividends and capital gains (Arizona has a subtraction for a portion of certain long-term gains, so check the current form instructions)
• Wages and self-employment income

With a flat rate, timing income across years matters less for state tax than in progressive states. A $100,000 conversion in one year costs about the same as two $50,000 conversions, at the state level.

Social Security exempt

Arizona does not tax Social Security benefits. Any portion included in federal AGI is subtracted on the Arizona return. Railroad retirement benefits get similar treatment.

For early retirees, this matters later. If you delay Social Security to 70, a large chunk of your retirement income will be state-tax-free in Arizona.

Pension subtraction

Arizona allows a subtraction of up to $2,500 for pensions from the federal government, the state of Arizona, and Arizona political subdivisions and certain public retirement systems. Military retirement pay is fully excluded from Arizona income.

Private pensions, IRAs and 401(k)s don't get a special subtraction; they're taxed at the flat rate. At 2.5%, the cost of not getting a subtraction is small. On $40,000 of IRA withdrawals, the state bill is about $1,000 before deductions.

Property taxes

Arizona property taxes are set locally and, for owner-occupied homes, are generally moderate compared with national averages. The state also offers programs that may help older homeowners, including a senior valuation protection option that can freeze a home's assessed value for qualifying owners with limited income, plus exemptions for widows, widowers and people with disabilities. Income and asset limits apply and change, so check with your county assessor.

Sales taxes (called transaction privilege tax in Arizona) are levied at the state, county and city level, and combined rates in many cities are in the high single digits. Groceries are exempt from the state portion but some cities tax them.

Example

Illustration. Hypothetical married couple, both 56, retired from private-sector jobs, living in Arizona. Their income for the year:

Before Arizona's standard deduction, $58,000 times 2.5% is $1,450. After the deduction, the actual bill would be lower. In a state with a 5% to 6% rate, the same income might cost $2,500 to $3,500. In a no income tax state it would be $0, but property taxes, insurance and housing costs may be higher. At these rates, the state tax line is rarely the deciding factor; health care access, climate and family usually matter more.

Arizona and the federal plan

The low flat rate makes Arizona friendly to the classic FIRE playbook: fill the low federal brackets with Roth conversions, harvest gains in the federal 0% bracket, and keep income low enough for ACA premium credits. The state adds a small cost to each step but rarely changes the decision. The bigger Arizona-specific costs are usually summer cooling, water and, in some areas, wildfire risk affecting insurance.

Moving to or from Arizona

Arizona taxes residents on all income and nonresidents on Arizona-source income. Part-year residents split the year. Many retirees spend winters in Arizona and summers elsewhere, which is pleasant for the body and complicated for the paperwork. If you keep homes in two states, be clear about which one is your domicile, and make your driver's license, voter registration, vehicle registration and tax filings tell the same story.

Coming from a higher-tax state like California, expect your old state to look at where you spend your time and where your closest connections are. Do large conversions after you've fully moved.

Common Arizona mistakes

• Assuming retirement income is fully exempt; only Social Security and military pay are.
• Forgetting city sales taxes on groceries in some cities.
• Missing county senior property tax programs because the deadline passed.
• Ignoring the impact of conversions on ACA credits, which usually matters far more than the 2.5% state tax.

Federal taxes still apply

Whatever Arizona does, the federal system still sets the base. For 2026 the federal standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly, and long-term capital gains can fall in a 0% bracket at lower incomes. Many early retirees aim to fill the low federal brackets each year with Roth conversions or gain harvesting. State tax then rides on top, so check how Arizona treats each type of income before deciding how much to convert. Social Security can become partly taxable federally as other income rises, and Medicare premiums later depend on income from two years earlier. A year of very low income can be just as wasteful as a year of very high income, because unused low brackets disappear on December 31. See 2026 tax brackets for FIRE.

Health coverage before Medicare

Before Medicare at 65, most early retirees in Arizona buy coverage through the ACA Marketplace (HealthCare.gov or the state exchange). Premium tax credits depend on household income, so the same withdrawal choices that drive Arizona income tax also drive what you pay for insurance. Price plans for your actual county, since insurer choice and premiums vary a lot between metro and rural areas. If your taxable income will be very low, check Medicaid eligibility rules for Arizona too. Our guides to the ACA subsidy cliff and managing MAGI go deeper.

One practical tip: estimate next year's income before open enrollment, then pick withdrawals to land where you planned. Surprises in either direction get reconciled on your federal return, and from 2026 there is no cap on repaying excess advance credits.

Your Arizona planning checklist

Use this as a starting list when you are weighing a move or planning withdrawals. Work through it a year before you leave your job, and again each fall before you decide on Roth conversions.

• Confirm the current flat rate and standard deduction on the Arizona DOR site.
• Claim the Social Security subtraction if any benefits are in federal AGI.
• Claim the government pension subtraction (up to $2,500) or military exclusion if eligible.
• Check county senior property tax programs and deadlines.
• Compare city sales tax rates, including on groceries, before choosing where to live.
