Arizona taxes some retirement income but not all of it

Arizona does not tax Social Security benefits, but it does tax distributions from retirement accounts like 401(k)s and traditional IRAs. The state also taxes pension income, though military pensions receive special treatment. If you receive income from a Roth IRA or Roth 401(k), those withdrawals are not taxed by Arizona. The key distinction is the source of the money: Social Security is protected, but money you saved in tax-deferred accounts during your working years becomes taxable when you withdraw it.

Arizona's income tax rates range from 2.55% to 4.5% depending on your total income, so the tax on retirement distributions is typically lower than federal rates. However, you may owe federal income tax on the same distributions, which can add significantly to your bill. Understanding which income Arizona taxes helps you plan withdrawals and potentially reduce your overall tax burden.

Key Takeaways

  • Arizona does not tax Social Security benefits, regardless of your total income or filing status.
  • Distributions from traditional 401(k)s, traditional IRAs, and pension plans are taxed as ordinary income by Arizona at rates between 2.55% and 4.5%.
  • Roth IRA and Roth 401(k) withdrawals are not taxed by Arizona because the contributions were made with after-tax dollars.
  • Military pensions are fully exempt from Arizona state income tax, while federal employee pensions and other government pensions are taxed.
  • You may owe both Arizona and federal income tax on the same retirement distributions, so check your federal obligations separately.

How Arizona taxes traditional retirement accounts

Money you withdraw from a traditional 401(k) or traditional IRA is treated as ordinary income by Arizona and taxed at your marginal rate. If you earned $50,000 in retirement distributions in a given year, Arizona taxes that $50,000 just as it would tax $50,000 in wages. The state does not offer a special deduction or exclusion for retirement account withdrawals the way some states do.

Pension income from a former employer follows the same rule: it is taxed as ordinary income. This includes pensions from private employers, state government jobs, and federal government jobs. The only major exception is military pensions, which Arizona exempts entirely from state income tax. If you receive a pension from the U.S. military, you owe Arizona nothing on that income.

Arizona does allow you to deduct contributions to a traditional IRA if you meet federal income limits, but that deduction reduces your federal taxable income, not your Arizona income. Once the money is withdrawn, Arizona taxes it.

Roth accounts and tax-free withdrawals

Roth IRAs and Roth 401(k)s work differently because you fund them with after-tax dollars. When you withdraw money from a Roth account in retirement, Arizona does not tax those withdrawals. This applies to both the contributions you made and the earnings that accumulated inside the account, as long as you follow the federal rules for may have access to withdrawals (generally, the account must be at least five years old and you must be at least 59½).

The advantage of a Roth is that you pay tax on the money going in, but then never pay tax on it again in Arizona. If you expect to be in a higher tax bracket in retirement, or if you expect Arizona's tax rates to rise, a Roth can be a useful tool. However, Roth conversions—moving money from a traditional IRA to a Roth—trigger a tax bill in the year of conversion, both federally and in Arizona.

Social Security and other untaxed income

Arizona is one of the few states that does not tax Social Security benefits under any circumstances. Even if you have substantial other income, your Social Security check is never subject to Arizona state income tax. This is true whether you receive Social Security as a retiree, as a surviving spouse, or as a dependent child.

Other income sources that Arizona does not tax include Supplemental Security Income (SSI) and certain railroad retirement benefits. However, these exemptions explore only to the specific income source—if you also receive a pension or retirement account distributions, those are taxed normally.

Military and government pensions

Arizona fully exempts military pensions from state income tax. If you retired from the U.S. Army, Navy, Air Force, Marines, Coast Guard, or Space Force, your entire pension is free from Arizona taxation. This exemption applies regardless of when you retired or how much you receive.

Federal employee pensions and state government pensions (from other states or from Arizona itself) are not exempt and are taxed as ordinary income. If you worked for the federal government and receive a Civil Service Retirement System (CSRS) or Federal Employees Retirement System (FERS) pension, Arizona taxes it. The same applies to pensions from other states' government employees.

How to report retirement income on your Arizona return

If you file an Arizona income tax return, you report retirement account distributions on Form 140, Arizona's resident income tax return. The amount goes on the line for federal taxable income, and then you make any Arizona-specific adjustments—such as subtracting military pension income or Social Security benefits if applicable.

Your financial institution or former employer will send you a Form 1099-R for retirement account distributions or a Form 1099-MISC for certain pension payments. Use the amounts on these forms to fill out your return. If you are unsure whether a particular income source is taxable in Arizona, the Arizona Department of Revenue website has guidance, or you can contact a tax professional.

Arizona does not require you to make estimated tax payments on retirement income, but if you withdraw a large amount in a single year, you may want to have taxes withheld from the distribution to avoid a surprise bill. You can request withholding directly from the institution managing your account.

Planning withdrawals to minimize Arizona taxes

Because Arizona taxes retirement account distributions but not Social Security, one strategy is to delay claiming Social Security until you can live primarily on non-taxable income. If you can cover your expenses with Social Security and Roth withdrawals, you reduce your Arizona tax bill significantly.

Another approach is to spread large withdrawals across multiple years if possible. Because Arizona's tax rate increases with income, taking $100,000 in one year may push you into a higher bracket, while taking $50,000 in each of two years may result in lower total tax. This is especially useful if you are doing a Roth conversion or taking a large lump-sum distribution.

If you have both traditional and Roth accounts, prioritize withdrawing from Roth accounts first in retirement to keep your taxable income lower. This strategy works only if you have enough in Roth accounts to cover your needs, but it can significantly reduce your Arizona tax burden over time.

Frequently Asked Questions

Do I have to pay Arizona income tax on my 401(k) withdrawals?

Yes, unless you have a Roth 401(k). Withdrawals from a traditional 401(k) are taxed by Arizona as ordinary income at your marginal rate. Roth 401(k) withdrawals are not taxed by Arizona.

Is my military pension taxed in Arizona?

No. Arizona exempts all military pensions from state income tax, regardless of the amount or when you retired. Federal employee pensions and other government pensions are taxed normally.

What if I receive both Social Security and a pension?

Your Social Security is not taxed by Arizona. Your pension is taxed as ordinary income. You report them separately on your return, and only the pension amount is subject to Arizona tax.

Can I reduce my Arizona taxes by taking withdrawals from a Roth instead of a traditional account?

Yes. Roth withdrawals are not taxed by Arizona, so if you have both types of accounts, withdrawing from your Roth first keeps your taxable income lower and reduces your state tax bill.

Do I owe federal tax on the same retirement income Arizona taxes?

Usually yes. Arizona and federal tax are separate, so you may owe both on the same distribution. Social Security is an exception—it is not taxed by Arizona and is only partially taxable federally under certain conditions. Consult a tax professional about your specific situation.
