Do expats pay state taxes? The sticky states, the free ones, and the clean exit

By Skyler Bissell · August 6, 2026 · 8 min read

At $150,000, our engine puts the gap between a San Francisco tax bill and a Seattle one at $7,924 a year, all of it state-level, since the federal math is identical. That number is usually discussed as a moving-to-Texas story. It is also the stake in a quieter game: whether your state believes you left at all. The IRS question ("do Americans abroad still file?") has a clear yes. The state question has fifty answers, and four or five of them are built to keep saying no, you never left.

Why the state question survives the move

States never signed your tax treaty. The treaties, exclusions, and credits that keep Americans abroad from double federal taxation are federal machinery, and a state is free to ignore all of it. What a state cares about is residency under its own law, and most define it through domicile, which persists until replaced. Sell the car, ship the furniture, land in Lisbon: if your state still counts you as domiciled, it can still expect a resident return on your Portuguese salary. The practical trigger is usually mundane: a W-2 with an old address, a spouse who stayed behind, a house that never sold, a driver's license quietly renewed.

The three tiers of states

Tier one: nothing to escape. Nine states tax no wage income: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Leave from one of these and the state chapter of your move is a page long. The engine shows what tier one is worth in place: the same $150,000 single filer keeps an effective all-in rate of 22.7% in Austin and 22.7% in Miami, against 29.4% in San Francisco and 31.1% in New York. Washington is the honest asterisk: its wage premiums put Seattle at 24.1% rather than a clean federal-only figure, and it taxes large capital gains, though never salary.

Tier two: the ones that let go. Most states release a genuine leaver without drama. You file a part-year resident return for the moving year, income after the move date stays out of it, and future filings exist only if state-source income continues: a rental property, a pass-through business, board fees. Keep the paper trail that shows the move date and the story ends there.

Tier three: the sticky ones. California, Virginia, New Mexico, and South Carolina interpret domicile the way a museum interprets a loan: yours is still theirs until formally transferred. Virginia's position is explicit, per Virginia Tax: moving abroad without establishing domicile in another US state leaves Virginia domicile intact, resident return and all. New Mexico and South Carolina run the same logic. California is its own genre: the Franchise Tax Board weighs closest connections across everything you own and visit, with a statutory safe harbor for employees abroad on a contract of 546 consecutive days or more, visits home capped around 45 days a year. New York deserves an honorable mention for a different trap: keep a New York abode and spend too many days back, or work remotely for a New York employer under its convenience rule, and the state-and-city stack returns. That stack is real money: $12,558 a year separates New York from Miami on the same $150,000 in our engine.

The stakes compound with tenure, which is what makes the paperwork worth an afternoon. Hold that New York exposure through a five-year posting and it runs toward $63,000 at this salary level, before penalties and interest on anything filed late. The same five years from a Texas or Florida base cost nothing in state filings and nothing in audit surface. Numbers that size are why cross-border advisors treat the DMV visit as seriously as the visa appointment.

The clean exit, step by step

1. Sequence the exit if your state is sticky. The reliable pattern is two moves: first re-domicile inside the US to a tier-one state, then go abroad. Virginia releases you to Florida in a way it will not release you to Portugal, and a Florida domicile asks nothing of you while you are gone.
2. Move the paper ties, all of them, before the flight. Driver's license, voter registration, vehicle titles, mailing address, primary bank branch, estate documents. Sticky-state auditors read these like a diary, and the cheapest evidence is the kind you created on time.
3. Cut the fat ties or price them. A kept house, a spouse who stays, kids in local school: each is a heavy weight on the residency scale. Keep them knowingly, with advice, or lose the argument years later with interest.
4. Document the departure date. The foreign lease, the shipping invoice, the one-way boarding pass. The part-year return you file for the moving year hangs on that date, and audits arrive after memories fade.
5. File the right returns after year one. From a clean exit: nothing, unless state-source income continues, which files as nonresident. If you claimed the federal exclusion, do not assume the state honored it; several never adopted it, so a state that still considers you resident taxes the income your 1040 excluded.
6. Mind the comeback rules. Statutory-residency day counts apply when you return or visit long: California's safe-harbor visit cap, New York's day-plus-abode test. The exit holds only as long as the calendar backs it.

The federal half of the abroad picture, the exclusion and the credit, is covered in the foreign earned income exclusion for 2026 and the broader US taxes after moving abroad. The state layer is also a reason destination math starts at home: the same Berlin offer clears a different bar for a Texan than for a Californian who has not exited yet, which you can see by running Austin vs Berlin against your own city, or any pair in the calculator. For how sub-national tax plays worldwide, the country map is in how countries tax your salary and the outcomes in take-home pay by country.

FAQ

Do I have to file a state tax return if I live abroad?

It depends on your last state, whether you broke domicile, and whether any income still sources there. From a no-tax state, nothing. From most middle-ground states, a part-year return for the moving year and then only if state-source income (a rental, a business) continues. From a sticky state where you never formally exited, a full resident return on worldwide income can still be due.

Which US states have no income tax?

Nine: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Washington levies wage-based premiums and a capital-gains tax above a high threshold, and New Hampshire taxed interest and dividends until that tax's 2025 repeal, so the nine are not perfectly identical, but none taxes ordinary salary.

What is California's safe harbor for expats?

A statutory presumption of nonresidency for Californians abroad on an employment contract for at least 546 consecutive days, with visits back capped around 45 days a year and limits on intangible income. Outside the safe harbor, California applies a closest-connections test to everything: home, spouse, doctor, gym, storage unit. The Franchise Tax Board's Publication 1031 is the rulebook.

Does the foreign earned income exclusion reduce state taxes?

Often not. States write their own tax codes, and several, California included, never adopted the exclusion, so income the IRS excused can remain fully taxable on a resident state return. The exclusion is a federal tool; the state answer comes from breaking residency, and it is the only answer the stickiest states respect.

Six items, one afternoon at the DMV, and a folder of dated paper: that is the whole insurance policy. Do it in the right order and the state chapter of your move closes before the plane boards. Do it late and you will be explaining your gym membership to an auditor in a state you have not seen in three years.
