Federal U.S. taxes follow citizenship, so most expats know they still file a federal return. State taxes are different and often overlooked: whether you still owe state tax after moving abroad depends on the state, and some are far harder to leave than others. Getting this wrong can mean an unexpected state return long after you've left the U.S.
Domicile vs residency
Two concepts drive most state questions, and they aren't the same:
Residency is generally about where you physically live and spend time in a given year.
Domicile is your true, fixed, permanent home — the place you intend to return to. You can be physically abroad yet still be domiciled in a state, which can keep you on the hook there.
Moving abroad ends physical residency, but it does not automatically change your domicile. Several states look to domicile, so leaving the U.S. without affirmatively breaking domicile can leave a filing obligation behind.
The 'sticky' states
A handful of states are known for making it hard to shed state residency/domicile while abroad. The details vary and change, but these commonly come up:
State
Reputation
General theme
California (CA)

Aggressive on domicile; 'closer connection' facts matter
New Mexico (NM)

Domicile-based; can continue absent a clear break
South Carolina (SC)

Domicile can persist abroad without affirmative steps
No-income-tax states (e.g. TX, FL, WA)

No state income tax to owe in the first place
This list is illustrative, not exhaustive, and state rules change. Treat it as a prompt to check your prior state's rules rather than a definitive ruling for the current year.
How people break state residency
Where a state looks to domicile, simply being abroad often isn't enough on its own. Steps that commonly support a clean break (the right mix is fact-specific) include:
Establish a new domicile abroad and document the intent to remain there.
Sever ties to the old state — driver's license, voter registration, vehicle registration, and similar where appropriate.
Address property and bank accounts that tie you to the state, to the extent practical.
Keep records of days, moves, and ties, since sticky states can examine the facts later.
Breaking domicile is fact-and-evidence driven, and overreaching can backfire. This is general information; the specifics of your former state and circumstances warrant professional guidance.

Frequently asked questions
I moved abroad — do I still have to file a state return?
It depends on the state and your domicile — some states look to domicile rather than physical presence, so being abroad doesn't automatically end the obligation. Confirm your former state's rules for the current year.
Which states are hardest to leave?
California, New Mexico, South Carolina and Virginia are known as 'sticky' domicile states, while states with no income tax generally aren't a concern. The details vary and change, so check your specific state.
How do I break state residency for tax purposes?
Establish a new domicile and sever meaningful ties to the old state, with documentation. Because this is fact-specific and states can examine it later, professional guidance is warranted rather than a one-size-fits-all checklist.
