401(k) Rollover in Arizona
Arizona taxes 401(k) distributions as ordinary income at up to 2.5% flat. A correctly executed direct rollover avoids all state tax. A failed rollover adds Arizona income tax on top of the federal bill.
What Arizona residents need to know
- Arizona has a flat 2.5% income tax at all income levels (unchanged for 2026) — one of the lowest state rates in the country.
- Arizona taxes private 401(k) and IRA distributions as ordinary income at 2.5%. There is no general retirement income exclusion for private plans.
- Arizona offers only a small $2,500 subtraction for U.S. government and Arizona state/local government pensions (not private 401(k)s), and fully exempts military retirement pay and Social Security.
- A failed 60-day rollover adds the distribution to Arizona income at 2.5%; a successful direct rollover has no Arizona tax consequence.
- The $2,500 government-pension subtraction does not apply to other states' government pensions or to private-sector plans.
Watch out for
- Do not expect a retirement exclusion on a private 401(k) or IRA in Arizona — the $2,500 subtraction is limited to specific government plans. The saving grace is simply the low 2.5% rate.
- A Roth conversion is taxed as ordinary income at 2.5% with no offsetting subtraction.
Good news
Arizona's flat 2.5% rate means even a fully-taxable failed rollover carries a comparatively small state bill — on a $200,000 distribution, the Arizona tax is roughly $5,000, versus far more in high-rate states.
The right move for Arizona residents
The most important step is the same in every state: do a direct rollover — custodian-to-custodian, no check issued to you. This eliminates the 20% mandatory federal withholding, the 60-day deadline risk, and all state tax exposure in one step.
