Does Arizona Tax Social Security? The Full 2026 Retiree Tax Picture

No, Arizona does not tax Social Security. Your benefits are fully exempt from Arizona income tax, even the portion that is taxable on your federal return. That single fact draws thousands of retirees to the state every year, but it is only the first line of a retiree tax picture that is genuinely one of the friendliest in the country. If you are retiring in Arizona or moving here for retirement, here is the whole picture in plain terms, with the numbers that matter for your plan.

How does Arizona tax retirement income?

Arizona uses a single flat income tax rate of 2.5% on taxable income, one of the lowest in the nation, and it treats different retirement income sources very differently. Here is the map:

Put that together and the Arizona rate is low and the base is narrow: your two biggest income sources in retirement, Social Security and, for many, an IRA, are either exempt or taxed at just 2.5%. On $60,000 of IRA withdrawals, Arizona takes about $1,500; a retiree in a state with a 6% rate and no Social Security exemption could pay several times that.

What about estate and inheritance taxes?

Arizona has neither. There is no state estate tax and no inheritance tax, so the only estate-tax question for an Arizona resident is the federal one, which reaches only very large estates. For retirees relocating from states like Oregon, Washington, or Illinois that impose their own estate taxes at far lower thresholds, this alone can reshape a legacy plan.

The new 2026 senior deduction (federal, but it matters here)

This one is new and worth understanding, because it is temporary and income-sensitive. For tax years 2025 through 2028, filers age 65 and older get an extra federal above-the-line deduction of up to $6,000 (single) or $12,000 (married, both 65+), on top of the existing extra standard deduction for seniors. You do not have to itemize to claim it.

The catch is the phase-out. It starts shrinking once modified AGI passes $75,000 single or $150,000 married, and disappears entirely above $175,000 and $250,000. That phase-out band is exactly where Roth conversion timing earns its keep: keeping income under the threshold in a given year can preserve thousands of dollars of deduction, which is the kind of move worth modeling before you take a large IRA withdrawal.

A simple two-retiree comparison

Meet two 67-year-old married couples, each with $40,000 of Social Security and $50,000 of IRA withdrawals, so $90,000 of total income:

Numbers are rounded to make the shape clear, and your real figures depend on your exact income mix. The point is the direction and the size: for a typical retiree, choosing Arizona is worth low-four-figures a year in state tax, every year, plus the estate-tax difference at the end.

What Arizona does not give you a break on

Honesty matters, so here is the other side. Arizona still taxes your IRA and 401(k) withdrawals and your private pension at 2.5%, it has no special break for those sources beyond the flat low rate, and Arizona sales tax (the transaction privilege tax) runs higher than many states once you add city and county rates. Property taxes are moderate, not zero. The state is retiree-friendly on income and estate taxes; it is average on consumption taxes. A good plan accounts for all three.

Where this gets actionable is the interplay: the low 2.5% rate makes Arizona an unusually good place to do Roth conversions in your pre-required-distribution years, converting IRA dollars while the state rate is low and before RMDs and Social Security stack your income up. If you are moving here from a higher-tax state, the timing of that move relative to a big conversion or an equity sale is itself a planning decision; establishing Arizona domicile cleanly is the companion piece.
