Do US Expats Still Owe State Taxes?
Why moving abroad doesn't always end your U.S. state tax obligation, which states are 'sticky', and how domicile differs from residency.
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.
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) | Sticky | Aggressive on domicile; 'closer connection' facts matter |
| New Mexico (NM) | Sticky | Domicile-based; can continue absent a clear break |
| South Carolina (SC) | Sticky | Domicile-focused analysis |
| Virginia (VA) | Sticky | Domicile can persist abroad without affirmative steps |
| No-income-tax states (e.g. TX, FL, WA) | Easiest | No state income tax to owe in the first place |
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.
