Updated August 6, 2026. Quick answer: a federal statute forbids any state from taxing the retirement income of someone who is not its resident or domiciliary. The protection is real and it is worthless until domicile is actually broken — and leaving the country does not break it by itself. California’s much-cited safe harbour, in particular, is built around an employment contract and does not help a retiree.
The federal shield, and the closed list it protects
4 U.S.C. §114(a): “No State may impose an income tax on any retirement income of an individual who is not a resident or domiciliary of such State.”
The section defines what counts, and the list is closed: qualified plans under §401(a), SEPs, 403(a) and 403(b) annuities, IRAs, 457 plans, governmental plans, and military retired or retainer pay. What it does not cover matters just as much, because this is where a state can still reach you after you have gone: wages, self-employment income, interest and dividends, capital gains, rental income, income from property physically in the state, severance, and restricted stock or RSU vesting.
There is also a qualifier that gets dropped almost everywhere it is discussed. For nonqualified deferred compensation, the protection attaches only where payment is made as a series of substantially equal periodic payments over life or a term of at least ten years. A lump sum is a different case. If your plan is to leave and take a large one-off distribution, that is precisely the situation the general rule may not cover.
Why moving abroad does not end domicile
Domicile is not where you are. It is the place the law still regards as your permanent home, and you have exactly one at a time. You keep the old one until you establish a new one, which is why moving between states and moving out of the country are different problems: a state can ask which US state you moved to, and “none” is an uncomfortable answer.
The general mechanics — how the tests actually work, why counting days is the wrong instinct, and what evidence states accept — are on the domicile page, and they apply here unchanged. This page is about what is different when the destination is not a state.
California: the safe harbour that is not for retirees
This is the single most consequential misunderstanding in this area. California does have a statutory safe harbour, and it is genuinely useful — to employees.
Cal. Rev. & Tax. Code §17014(d) covers a Californian absent from the state for an uninterrupted period of at least 546 consecutive days under an employment-related contract. Returns totalling no more than 45 days in a taxable year are disregarded, and an accompanying spouse gets the same treatment. It does not apply if income from intangible property exceeds $200,000 in a year the contract is in effect, or if the principal purpose of the absence is avoiding tax.
Read the gate: an employment-related contract. A retiree living on Social Security, a pension and an IRA has no employer sending them anywhere and does not qualify on the statute’s face. They fall back on the general facts-and-circumstances test — where domicile means, in California’s own words, “the location where a person has the most settled and permanent connection, and the place to which a person intends to return when absent”, the burden sits on the taxpayer, and “if there is a doubt on the question of domicile… the domicile must be found to have not changed.”
That last clause is the whole problem in one sentence. Doubt is not neutral. It is resolved against you.
The move has a money side as well as a paperwork side
Residency, the accounts themselves and the order things are done in all interact, and an adviser can look at them together before a move is treated as settled.
Before you start, what actually happens. The form is run by Kapitalwise, our advisor-matching partner. Kapitalwise sends your details to advisers who pay for the introduction, so expect calls and texts. Clear Money Guide is paid when you submit the form, whether or not you ever hire anyone. This is free to you and there is no obligation to hire anyone.
The Kapitalwise form opens here. You stay on this page.
What happens when you press the button
It asks about nine questions (age, investable assets, location), then your name, email and phone number, and verifies the phone by text. Nothing loads and nothing reaches Kapitalwise until you press the button. Submitting the form does not guarantee an adviser or a match. This matching form is not tax or legal advice.

Virginia, and the states people assume belong here
Virginia addresses this directly, which is unusual and worth quoting. Its Department of Taxation states that “[u]nless you have established residency in another state, you will still be considered a domiciliary resident of the Commonwealth, and will be required to file Virginia income tax returns”, and that “[t]he fact that a person has been absent from Virginia, whether in the foreign service of the United States or in the exercise of private enterprise, does not in any way cancel out their Virginia citizenship or legal domicile.”
We checked the rest of the usual list rather than repeating it, and it did not survive intact. South Carolina’s statute does define a resident as someone domiciled there, but we could not verify the Department of Revenue’s own domicile test from any source we could read, so we do not describe one. And New Mexico may not belong on this list at all: its own Taxation and Revenue Department describes residency in terms of a 185-day physical presence test, which is a different doctrine from domicile-until-abandoned. We could not reach the statute to check whether a separate domicile prong exists alongside it. If the test is genuinely day-count, a retiree who leaves and stays away is in a materially better position in New Mexico than in California.
What the evidence actually looks like
California’s own tribunal has published the factor list it applies, and it is a better checklist than anything written for consumers. It weighs the location of every residence you own; where a spouse and children live; where you claim a homeowner’s property tax exemption; where you file returns and what residency you claim on them; where your bank accounts sit and where card transactions originate; memberships in social, religious and professional organisations; vehicle registration; driver’s licence; voter registration and voting history; where you see doctors, dentists, accountants and lawyers; where you hold professional licences; and where you own investment property.
Two things follow. Intent is proved by acts, not by declarations — a statement that you meant to leave counts for little against a driver’s licence you kept. And the list is mostly free to satisfy: registering to vote where you now live, moving the professional relationships, closing the old accounts. The expensive items are the ones people keep for sentimental or practical reasons, and the house you did not sell is the one that does the most damage.
Do as much of it as you can before you leave. Every one of these is harder to arrange from eight time zones away.

Honest gaps. FTB Publication 1031 is cited constantly in this area and we could not fetch it — ftb.ca.gov refused us on every path — so the California statements above rest on the statute and a Board of Equalization opinion instead, both primary. South Carolina’s administrative test and the full text of New Mexico’s residency statute were both unreachable. And Virginia’s guidance discusses abandoning domicile for another state; it does not give a foreign example, so how it applies to someone who moves to a country rather than a state is not something we can state from its own words.
