State residency when you move abroad: how to actually leave

The U.S. federal tax system follows you abroad. State tax systems generally do not — but only if the state agrees you're no longer one of theirs. Most states are happy to let you go the moment you stop physically living there. A few — most notoriously California, New York, New Mexico, Virginia, and South Carolina — keep their hooks in for years if you're not careful.

This article explains how state residency actually works for expats, why these states are difficult, and the practical steps to sever residency cleanly before moving abroad.

Three categories of states

For expats, U.S. states fall into three groups:

Easy-leave states

Most states use a simple test: if you don't live here, you're not a resident. Examples: Florida, Texas, Nevada, Washington, Wyoming, Tennessee, South Dakota, Alaska, New Hampshire — and most of these have no state income tax anyway, so it doesn't matter. Other easy-leave states include Arizona, Colorado, Illinois, Indiana, Michigan, Pennsylvania (mostly).

If your last U.S. state was one of these, your move abroad probably already severed residency. File a part-year resident return for the year you moved, and you're done.

Moderate-difficulty states

Most income-tax states will release you when you actually move — but require evidence: voter registration change, driver's license surrender, sale of property, etc. The IRS-state interaction is straightforward, but you must affirmatively show you left. Examples: Massachusetts, Maryland, Georgia, North Carolina, Ohio, Oregon.

Sticky states

A few states use a "domicile" test that is nearly impossible to break by simply moving abroad. They presume you're still a resident — and remain so for tax purposes — until you prove you've established domicile elsewhere with the intent to never return.

This is the hard problem. The major sticky states:

• California
• New York
• New Mexico (uniquely aggressive about expat residents)
• Virginia
• South Carolina

These states will continue to tax your worldwide income for years after you leave, unless you do the work to formally sever residency.

The two tests states use

State residency uses two parallel tests, and you can be caught by either one.

1. Statutory residency (days)

Most states count you as a resident if you spend more than 183 days in the state during the year. This is a hard rule — straight day-count, no intent analysis.

For expats who genuinely live abroad and rarely visit, this test is easy to pass. The trap is for digital nomads or part-time expats who maintain a U.S. home and visit "just for a few weeks at a time" that add up to over half the year.

2. Domicile (intent)

A domicile is the one place in the world you consider your permanent home — the place you'd return to if everything else fell apart. You have exactly one domicile at any time. To change it, you must:

1. Physically be present in the new place.
2. Intend to make it your permanent home — i.e., to remain indefinitely and not return.
3. Sever your previous domicile by abandoning it.

A foreign country can be your domicile — the law doesn't require domicile to be in a U.S. state. But proving you've established foreign domicile is harder than proving you've moved between states, because foreign countries don't issue "domicile certificates" and your visa often has an end date.

The sticky states presume you maintain U.S. domicile until you affirmatively rebut it. The burden is on you.

California's "domicile" trap

California uses a "domicile + presence" framework. Even if you spend zero days in California, you remain a California resident for tax purposes if California considers your domicile still in California — meaning you have not affirmatively abandoned California domicile and established a new one elsewhere.

The Franchise Tax Board (FTB) audits former Californians aggressively. They look at:

• Whether you sold or rented out your California home
• Whether you canceled your California driver's license
• Whether you re-registered your voter registration elsewhere
• Whether you closed California bank accounts
• Whether you canceled California-based professional memberships
• Whether your spouse and children moved with you
• Whether you store belongings in California
• Whether you describe California as "home" anywhere — including in social media
• The duration of your foreign assignment (definite end date = bad)

The FTB has published case law where individuals were held to be California residents despite living abroad for 5+ years, because their California ties (a kept-house, family, intent to return) outweighed their foreign ties.

New York's "permanent place of abode" trap

New York applies a particularly aggressive rule: if you maintain a permanent place of abode in New York and spend more than 183 days there, you're a statutory resident. But for domicile, New York looks at intent — like California.

A subtle point: even a property you don't live in can be a "permanent place of abode" if it's "maintained for your use" — a vacation house, an empty apartment kept for visits, even a relative's home where you have a permanent room.

New York's Department of Taxation and Finance routinely audits departing high earners. The "Dutchman rule" cases are notorious: people who moved to Connecticut or New Jersey but kept New York vacation homes were held to be New York residents.

New Mexico — the surprise

New Mexico has the strictest expat rule in the country. Under NMSA 7-2-2(N), a New Mexico domiciliary remains a New Mexico resident — and subject to New Mexico tax on worldwide income — even while continuously living and working abroad, unless they have abandoned New Mexico as their domicile.

Crucially, New Mexico does not count time spent abroad against the 183-day rule the way most states do. A New Mexico domiciliary working in Tokyo for 365 days a year is still a New Mexico resident if domicile wasn't severed.

If you have any New Mexico ties before moving abroad — house, mailing address, professional license, family — get this nailed down before you go. New Mexico's tax department is small but determined.

Virginia, South Carolina, others

Virginia uses a "place of abode" + intent test similar to New York. South Carolina applies the 183-day rule and also pursues domiciliaries who maintain SC ties. Other states (Maryland, Massachusetts, North Carolina, Oregon) are intermediate — they'll release you with reasonable evidence but won't presume your departure.

How to actually sever state residency

Do these in the calendar year you move abroad, and ideally before you leave:

1. Surrender your state driver's license. Get a foreign license, or a license from a no-tax state (FL, NV, TX, WA) if you'll be visiting the U.S. periodically.
2. Change your voter registration. Either to a no-tax state where you have ties, or — if you're a U.S. citizen abroad — register as a U.S. citizen voting from abroad through the FVAP / state expat program. Don't keep voting in your old state.
3. Sell or rent out your home in the state. If you must keep a property, rent it out arm's-length (real lease, market rate). Don't leave it empty "for visits."
4. Close state-only bank accounts. Move banking to a national bank with a foreign-friendly address policy (Schwab, Fidelity), or a foreign bank.
5. Cancel state-issued professional licenses (or move them to inactive status if you might return).
6. Update mailing addresses on every account — banks, brokerages, retirement accounts, insurance, IRS, Social Security. Use your foreign address or a mail-forwarding service tied to a no-tax state.
7. Move belongings and pets. Don't leave a "California room" stocked with your stuff at a family member's house.
8. File a part-year resident return for the year you left, explicitly indicating the date residency ended.
9. File a "non-resident" return going forward if you have any state-source income (rental income from a property in the state, etc.).
10. Keep records. Travel records showing you weren't in the state, foreign rental agreement, foreign tax returns paid as a resident, foreign utility bills in your name.

The fewer ties you maintain, the easier the case. The more ties (vacation home, family, accounts, drivers license, voter registration), the more vulnerable you are.

Federal vs. state — the practical interaction

Your federal return (1040) tells you nothing about state residency. Your state return is separate.

In the year you move abroad:

• Federal: full-year resident, worldwide income, FEIE/FTC for foreign-source portion.
• State: part-year resident from January 1 through your move date. Then either non-resident for the rest of the year (if you sever residency) or full-year resident (if you don't).

In subsequent years:

• Federal: continues unchanged.
• State: ideally, no state return at all. If the state continues to claim you, you file a non-resident return (or full-year resident, if losing) and pay state tax on your worldwide income.

The financial difference can be enormous. California's top rate is 13.3%. New York City + state is roughly 14%. A $200,000 expat salary in a sticky state with FEIE saves you $0 federal — but $25,000+ in state tax if the state still considers you a resident.

When to consider establishing a no-tax-state domicile before moving abroad

If you're leaving from a sticky state, consider relocating to a no-tax state (Florida, Texas, Nevada, Washington, Tennessee, South Dakota) for 6–12 months before your foreign move. Sever the sticky state's claim while you're physically in the U.S., establish your no-tax-state domicile clearly, then move abroad. Your abroad move now starts from a no-tax state, with no sticky state still claiming you.

This is what high-net-worth people leaving California or New York routinely do. It costs the inconvenience of an extra move but eliminates years of potential state-tax exposure.

Common state-residency mistakes

• Assuming "I moved" is enough. It isn't, for sticky states.
• Maintaining a "vacation home" in the state. This is the single strongest piece of evidence against you.
• Keeping the state driver's license "for visits." Don't.
• Filing a state return as a full-year resident because the software defaulted to it. You're then admitting residency.
• Voting in state elections after leaving. This is direct evidence of intent to remain a resident.
• Telling the state "I plan to come back." Domicile requires intent to not return. Don't undermine your case in writing.
