State residency is the tax status a U.S. state uses to decide whether a taxpayer is a resident, part-year resident, or nonresident for state income tax purposes. For U.S. expats, state residency often depends on domicile, time spent in the state, and the ties kept there, such as a home, driver’s license, voter registration, mailing address, employer, business interests, or plans to return.

Why it matters for U.S. expats

State residency matters because moving abroad does not automatically end state tax obligations. If a former state still treats an expat as a resident, it may tax worldwide income; if not, the expat may still need to file for state-source income, such as rental, business, wage, or property income connected to that state.

Common questions

1. Do U.S. expats have to file state tax returns?

Sometimes. It depends on the state, whether the expat is still considered a resident, and whether they have income sourced to that state.

2. Does moving abroad end state residency?

No. Moving abroad can help show that a taxpayer has left a state, but it does not automatically end state residency if the state still considers them domiciled there or connected to the state.

3. What is domicile?

Domicile is a taxpayer’s permanent legal home. It is usually the place a state believes the taxpayer intends to return to, even if they are currently living somewhere else.

4. What is the difference between state residency and domicile?

Domicile is about permanent legal home and intent to return. State residency can also depend on other rules, such as time spent in the state, whether the taxpayer keeps a home there, or whether they have state-source income.

5. Can a state tax foreign income?

Yes, if the state treats the taxpayer as a resident. Nonresidents are usually taxed only on income connected to that state.

6. What is state-source income?

State-source income is income connected to a specific state. This can include wages for work performed in the state, rental income from property there, business income from state activities, or gains from selling real estate located there.

7. Does the Foreign Earned Income Exclusion apply to state taxes?

Not always. Some states follow federal tax treatment more closely than others, while others have their own rules. Expats should not assume that excluding income federally also removes state tax exposure.

8. Which states are more difficult for expats?

California, New York, and Virginia are often more difficult because they have detailed residency and domicile rules. The right answer still depends on the taxpayer’s facts and the state involved.

9. How can expats show they changed state residency?

Useful steps may include changing a mailing address, updating a driver’s license and voter registration where appropriate, selling or renting out a former home, moving financial and professional ties, and keeping records that show the move abroad is permanent or long-term.

When to get help

Professional guidance is important when:

  • You moved abroad from a state with strict residency rules.
  • You still own or rent property in your former state.
  • Your spouse, children, employer, business, mailing address, or professional licenses are still connected to that state.
  • You have rental income, business income, equity compensation, or other income connected to a U.S. state.
  • You are unsure whether to file as a resident, part-year resident, or nonresident.
  • You want to break state residency before or after moving abroad.
  • You have not filed state returns because you assumed moving overseas ended the obligation.
