Yes, pensions are generally taxable in Arizona, but at a low flat rate of 2.5% and with several exemptions that erase the bill entirely for many retirees. Military retirement pay is fully exempt. Social Security and Railroad Retirement benefits are completely excluded. Pensions from federal retirement systems and from Arizona state or local retirement plans qualify for a $2,500 per-person subtraction. Private pensions and withdrawals from 401(k)s and traditional IRAs are taxed in full at the 2.5% rate.
How Arizona Taxes Pension Income
Arizona builds your state return on top of your federal adjusted gross income. Whatever shows up as taxable pension or retirement income on your federal 1040 flows into your Arizona return, where state-specific subtractions can remove some or all of it before the tax is calculated.1Arizona Legislature. Arizona Code 43-1001 – Definitions
Since 2023, Arizona has used a single flat 2.5% rate for all taxable income. There are no brackets. Pension payments, IRA withdrawals, wages, and investment income all face the same percentage, so the only real question for most retirees is how much of their pension escapes Arizona tax before the rate is applied.
Pensions That Are Fully Exempt
Military Retirement Pay
For tax years beginning after December 31, 2020, Arizona excludes 100% of retired or retainer pay from the uniformed services of the United States, with no dollar cap.2Arizona Legislature. Arizona Code 43-1022 – Subtractions From Arizona Gross Income This covers retirement pay from all branches, including the reserves. The military exemption sits on a separate line from the $2,500 government pension subtraction, so a retiree with both a military pension and a federal civil service pension can claim both.
Social Security and Railroad Retirement
Arizona fully excludes Social Security benefits. Any portion of your Social Security that is taxable on your federal return gets subtracted back out when you figure your Arizona adjusted gross income. Tier 1 and Tier 2 Railroad Retirement benefits included in your federal AGI get the same treatment.3Cornell Law School. Arizona Admin Code R15-2C-305 – Social Security and Railroad Retirement Benefits You still list these amounts on your Arizona return, but the subtraction zeroes them out.
The $2,500 Government Pension Subtraction
If your pension comes from a federal or Arizona government retirement system, you can subtract up to $2,500 of that income from your Arizona taxable income each year. For a married couple where both spouses receive qualifying pensions, each spouse claims their own $2,500, for up to $5,000 combined.4Arizona Department of Revenue. Arizona Form 140 Booklet – Section: Line 29a
Qualifying federal sources include the U.S. Government Service Retirement and Disability Fund, the Foreign Service Retirement and Disability System, and any other retirement plan established by federal law (not merely regulated by it). Qualifying Arizona sources include the Arizona State Retirement System, the Corrections Officer Retirement Plan, the Public Safety Personnel Retirement System, the Elected Officials’ Retirement Plan, optional retirement programs from the Arizona Board of Regents or community college districts, and plans run by Arizona counties, cities, or towns.2Arizona Legislature. Arizona Code 43-1022 – Subtractions From Arizona Gross Income
Watch the limits of this one. Government pensions from other states do not qualify. If you retired from California’s state pension system and moved to Arizona, your pension is fully taxable at 2.5% with no subtraction available.4Arizona Department of Revenue. Arizona Form 140 Booklet – Section: Line 29a Private-sector pensions from former employers don’t qualify either, regardless of where you earned them.
Private Pensions, 401(k)s, and IRAs
Distributions from private-sector pensions, 401(k)s, 403(b)s, traditional IRAs, and similar accounts are fully taxable in Arizona at the 2.5% rate. Arizona offers no subtraction for them. Whatever amount is taxable on your federal return flows directly into your Arizona income.5Arizona State Retirement System. Tax Information
Qualified Roth distributions are the exception. Because Arizona starts from federal AGI, and qualified Roth IRA or Roth 401(k) withdrawals are not included in federal AGI, they don’t appear in your Arizona taxable income either. If you’ve met the five-year holding period and are over 59½, Roth money comes out tax-free at both levels.
Arizona does not impose its own early withdrawal penalty. If you take money out before age 59½, the federal 10% additional tax may apply unless an exception fits your situation, but at the state level the early distribution is simply ordinary income taxed at 2.5%.6Internal Revenue Service.

If You Moved: Residency Rules
Residency decides which pension income Arizona can tax in the first place. The state presumes you’re a resident if you spend more than nine months of the year in Arizona, though you can rebut that presumption with evidence that your presence is temporary.7Arizona Legislature. Arizona Code 43-104 – Definitions Full-year residents are taxed on all pension income from any source. Part-year residents are taxed on pension income received during the months they lived in Arizona. Nonresidents owe Arizona tax only on income from Arizona sources.8Arizona Legislature. Arizona Code 43-1091 – Gross Income of a Nonresident
Here’s the point that catches people going the other direction: federal law prohibits any state from taxing the retirement income of a nonresident.9Office of the Law Revision Counsel. 4 USC 114 – Limitation on State Income Taxation of Certain Pension Income If you earned a pension from an Arizona employer and then moved out of state, Arizona cannot tax those pension payments. The protection covers qualified trusts, simplified employee pensions, 403(a) and 403(b) plans, 457(b) plans, IRAs, and government retirement plans.
Where to Claim the Subtractions
Each pension payer sends you a Form 1099-R by January 31 showing total distributions and the taxable amount. On Arizona Form 140 (full-year residents), you take your federal AGI and then apply the subtractions on the relevant lines:
- Line 29a: the $2,500 subtraction for qualifying federal or Arizona government pensions.
- Line 29b: the full military retirement pay exemption.
- Social Security and Railroad Retirement subtractions appear on separate lines as part of the standard Arizona adjustments.10Arizona Department of Revenue. Arizona Form 140 Booklet
Part-year residents file Form 140PY, which allocates income between the resident and nonresident portions of the year. The same subtractions are available, but you have to prorate them based on income allocable to the time you lived in Arizona.11Arizona Department of Revenue. Arizona Form 140PY Booklet
Setting Up Withholding So You Aren’t Surprised in April
Pension payments don’t have taxes withheld automatically the way wages do. You have to ask.
For federal withholding on regular, periodic pension payments, file Form W-4P with your plan administrator. You can set a specific amount or elect zero. If you never submit a W-4P, the payer defaults to withholding as though you’re single with no adjustments.12Internal Revenue Service. Form W-4P 2026 – Withholding Certificate for Periodic Pension or Annuity Payments Nonperiodic and eligible rollover distributions use Form W-4R instead.
For Arizona, withholding on pensions is voluntary. File Form A-4P with your pension payer and choose a withholding percentage between 0.5% and 3.5% of your taxable distribution.13Arizona Department of Revenue. Arizona Form A-4P Picking 2.5% roughly matches the flat rate for a taxpayer without large credits or deductions. You can change or cancel at any time by filing a new A-4P.
If withholding doesn’t cover your liability, Arizona requires quarterly estimated payments once your Arizona gross income passes $75,000 for single filers or $150,000 for joint filers, provided you met the same threshold the prior year. Payments are due April 15, June 15, September 15, and January 15.14Arizona Department of Revenue. Arizona Form 140ES Booklet
