Does the State Your Heirs Live In Affect Inheritance Taxes?
Quick answer
Not the way people fear — but yes in the way that actually costs money. Inheritance taxes are levied by the state where the person who died lived, not where the heirs live. Arizona has none, so when an Arizona resident dies, heirs owe no inheritance tax no matter what state they call home. What does follow your heirs is income tax: when your children withdraw from an inherited traditional IRA or 401(k) — which the SECURE Act generally forces within ten years — those withdrawals are taxed as ordinary income by their state of residence. A child in Arizona pays the flat 2.5%; a child in California pays up to 13.3%; a child in Nevada, Texas, or Washington pays nothing. On a seven-figure pre-tax balance, heir geography can swing the family's total tax bill by six figures — and you can plan around it.
Keep the two tax systems separate. Death taxes (estate and inheritance taxes) attach to the decedent: the federal estate tax applies only above $15 million per person in 2026, Arizona has no state-level death tax, and the handful of states with inheritance taxes — Kentucky, Maryland, Nebraska, New Jersey, Pennsylvania — tax the estates of their own residents (and real property located there), not beneficiaries who happen to live elsewhere. An Arizona decedent with a Pennsylvania daughter triggers nothing. The reverse — you owning a rental property in an inheritance-tax state — can, which is one reason out-of-state real estate deserves a look.
Income taxes work on the opposite principle: states tax their residents on income wherever it comes from. An inherited traditional IRA is a stream of untaxed ordinary income waiting to be recognized, and it gets recognized on your heir's tax return, in your heir's state, at your heir's rates. The ten-year rule concentrates that recognition into your children's peak earning years. A $1.5M pre-tax IRA flowing to a San Jose engineer gets stacked on a high salary and taxed at 32–37% federal plus 9.3–13.3% California. The identical account flowing to a sibling in Scottsdale faces the same federal bill but 2.5% state. Same parent, same account — materially different inheritance.
The assets that ignore heir geography are the same ones that ignore most taxes: Roth accounts (tax-free to any heir in any state) and appreciated taxable assets (the step-up in basis erases the gain regardless of where the heir lives — and Arizona's community property rules can double that benefit for married couples). This asymmetry is the planning lever. Every dollar you convert from traditional to Roth at Arizona's flat 2.5% is a dollar your California child will never run through Sacramento's brackets; every appreciated share you hold until death instead of selling passes state-tax-free everywhere.
Geography is also dynamic, and the ten-year window gives heirs room to use it. Distributions are taxed by residence in the year taken — a child planning a move from California to Nevada can defer inherited-IRA withdrawals until after the move (mind the annual-RMD requirement in years one through nine when the original owner died after RMDs began, and California's aggressive residency rules around the move year). None of this requires anyone to relocate; it requires the family to know the rules before the window starts running.
Map your beneficiaries by state before finalizing your Roth conversion plan. The standard conversion math compares your bracket today to your bracket in RMD years — but for money you will not spend, the honest comparison is your combined rate today (federal plus Arizona's 2.5%) against each child's combined rate during a forced ten-year payout. A California heir strengthens the conversion case by up to 13 percentage points; a Texas heir weakens it.
Match account types to heir geography where bequests allow it: Roth and step-up assets toward high-tax-state children, traditional dollars toward heirs in no-tax states, charity, or lower brackets. Equal value does not require identical assets — and an 'equal' split of account balances that ignores embedded taxes is not actually equal after tax.
If you own real estate outside Arizona, check the death-tax rules where it sits. Property in an inheritance- or estate-tax state can create the only death tax your family will ever face, and entity or trust ownership may neutralize it.
- Worrying about a nonexistent Arizona inheritance tax while ignoring the very real state income tax your heirs' home states will charge on inherited pre-tax accounts.
- Running Roth conversion math against your own future brackets only, when the marginal dollar is actually destined for a child in a 9–13% state.
- Splitting accounts 'equally' by balance across children in different states, which delivers unequal after-tax inheritances.
- Heirs taking the full inherited-IRA payout in year one out of caution — or in their last California year before a planned move — instead of timing distributions within the ten-year window.
- Forgetting out-of-state real estate. The decedent-side rules that don't apply to your Arizona assets can still apply to a Pennsylvania rental or a New Jersey condo.
