1. What changes on your annual tax bill

Both states tax retirement withdrawals, so this is a rate change rather than an exemption. California runs graduated to 13.3% (plus existing 1% mental health surtax included in that top rate; against Arizona at flat 2.5% — a top-rate difference of roughly 10.8 percentage points. On $100,000 of withdrawals that is on the order of $10,800 a year at the top of the schedule, before any exclusion either state allows.

California: Pensions, 401(k), and IRA distributions fully taxable as ordinary income — no age-based exclusion or retirement deduction. Arizona: Private pensions, 401(k), and IRA distributions fully taxable at 2.5%.

2. What changes at death: state estate tax

Neither state levies an estate tax. California: none Arizona: none Only the federal estate tax applies.

3. What changes at death: state inheritance tax

Neither state levies an inheritance tax. California: none Arizona: none

4. The one nobody prices: what probate costs your heirs

California uses a statutory-percentage fee model (Cal. Prob. Code §10810 (attorney) and §10800 (PR) — identical schedules, each computed on gross estate value: 4% of first $100,000; 3% of next $100,000; 2% of next $800,000; 1% of next $9,000,000; 0.5% of next $15,000,000; court-determined reasonable amount above $25,000,000. E.g., $500,000 estate = $13,000 each for attorney and PR.); Arizona uses a reasonable-fee model (UPC state: reasonable compensation for PR and attorneys (A.R.S. §14-3719); no percentage schedule.). Filing fees — California: $435 first-filed petition for letters (Gov. Code §70650, Statewide Civil Fee Schedule); a few counties add local surcharges (~$435-$500). Note each side’s petition triggers the fee. Arizona: ~$306 initial probate filing (Maricopa County Clerk of Superior Court); varies modestly by county

Probate cost in each state, specifically

California uses a statutory percentage schedule, so the fee is computable exactly, and its small-estate route can reach real property under a statutory cap. Arizona uses a “reasonable fee” standard with no schedule, and its small-estate route can reach real property under a statutory cap. Both states land in the same bucket on that question. Full figures with the governing statute, the court filing fee and the small-estate threshold: California probate cost and Arizona probate cost.

Four taxes, two states, one order of operations

Everything above changes together: what California stops taking on withdrawals, what Arizona does not take at death, and what probate costs in each. The order you do things in — when you establish domicile, when you convert, when you retitle property — changes the total, and some of it cannot be undone afterwards. If a move is genuinely on the table, here is what to look for in an advisor who knows both California and Arizona. If you would rather price it yourself first, the two-state comparison tool is free and asks for no email.

Will California still tax me after I move to Arizona?

Not on your retirement withdrawals, once you genuinely change domicile — but that is a harder test than a change of address, and what you leave behind stays in reach.

• Domicile is a test, not a mailing address. A departing state can and does audit residency. Days present, voter registration, driver’s licence, where your doctors and advisers are, and where you keep what you value all count.
• A Roth conversion is taxed where you live in the year you convert. Sequencing a conversion after establishing the new domicile is often worth more than the annual saving — see how all 51 jurisdictions tax Roth conversions.
