Breaking State Tax Residency When Moving Abroad: What Americans Actually Need to Do

# Breaking State Tax Residency When Moving Abroad: What Americans Actually Need to Do

In 2019, the California Franchise Tax Board won a $1.3 million judgment against Gilbert Hyatt, a former California resident who had moved to Nevada decades earlier. The dispute, which went to the US Supreme Court twice (*Franchise Tax Board of California v. Hyatt*, 587 U.S. ___ (2019)), centered on whether Hyatt had truly severed his California residency when he claimed he did. California argued he hadn't. The case dragged on for nearly 30 years.

Most Americans moving abroad assume that leaving the country ends their state tax obligations. It doesn't. While the IRS taxes US citizens on worldwide income regardless of where they live (see [IRS Publication 54](https://www.irs.gov/publications/p54)), states impose their own rules — and several of them are aggressive about keeping expats on the tax rolls. California, New Mexico, South Carolina, and Virginia are the four states widely recognized by tax practitioners as "sticky" because of their strict domicile standards.

This article covers what you need to do to legally break state tax residency when moving abroad, with emphasis on the states most likely to contest your claim.

Why the IRS Isn't Your Only Problem

The IRS and state tax authorities operate separately. The Foreign Earned Income Exclusion (FEIE) under IRC Section 911, which allows qualifying expats to exclude up to $126,500 of foreign earned income in tax year 2024 (adjusted annually for inflation per [IRS Rev. Proc. 2023-34](https://www.irs.gov/pub/irs-drop/rp-23-34.pdf)), is a federal provision. States aren't required to honor it, and many don't.

California, for example, does not conform to the federal FEIE. If California considers you a resident, it taxes your worldwide income at rates up to 13.3% — the highest marginal state rate in the country — with no foreign earned income exclusion. The California Franchise Tax Board (FTB) publishes [Publication 1031](https://www.ftb.ca.gov/forms/2023/2023-1031-publication.pdf), which governs residency determinations.

Nine states have no personal income tax at all: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire eliminated its interest and dividends tax at the start of 2025. If you're moving abroad from one of these states, you have no state residency problem to solve.

The Two-Part Test: Domicile vs. Statutory Residency

States generally use two concepts to determine residency:

**Domicile** is your true, fixed, permanent home — the place you intend to return to when you're away. You can only have one domicile at a time. Moving abroad doesn't automatically change your domicile; you must establish a new one, or at minimum demonstrate clear intent to abandon your prior domicile.

**Statutory residency** is a mechanical test, usually based on days present and whether you maintain a "permanent place of abode" in the state. In New York, for instance, spending more than 183 days in the state *and* maintaining a permanent place of abode for substantially all of the year makes you a statutory resident — even if your domicile is elsewhere (New York Tax Law § 605(b); see [NY Department of Taxation Publication 88](https://www.tax.ny.gov/pdf/publications/income/pub88.pdf)).

Expats moving abroad typically fail the domicile test, not the statutory one. If you're in Lisbon 340 days a year, you're not triggering the 183-day rule anywhere. But states can still argue your domicile remains stateside if you haven't severed enough ties.

The Four Sticky States

California

California's FTB uses a "closest connections" analysis. FTB Publication 1031 lists factors including where your spouse and children live, where you're registered to vote, where your driver's license is issued, where your vehicles are registered, where your professional licenses are held, and where your bank accounts are maintained. No single factor is decisive, and the FTB weighs them holistically.

California's *Safe Harbor* rule (R&TC Section 17014(d)) treats you as a nonresident if you're outside California under an employment-related contract for at least 546 consecutive days, with limited return days. This is the cleanest way out for employed expats, but it doesn't apply to self-employed individuals, retirees, or remote workers serving California clients.

New Mexico, South Carolina, Virginia

These three states, along with California, are frequently cited in expat tax planning resources as the most aggressive in pursuing former residents. Virginia applies a domicile test that emphasizes intent to return; the state's [Code § 58.1-302](https://law.lis.virginia.gov/vacode/58.1-302/) defines a resident as anyone domiciled in Virginia for any portion of the taxable year, regardless of physical presence.

South Carolina and New Mexico apply similar domicile-based frameworks. All four states have been known to assess taxes on expats who maintained bank accounts, driver's licenses, or voter registrations in-state.

The Practical Checklist: Severing Ties

Below is a list of actions that practitioners commonly recommend before or during a move abroad. Completing more of them strengthens your case.

Documents and Registrations

• **Surrender your state driver's license** and obtain a license in your new country, or switch to an international driving permit plus a non-driver ID from a no-tax state if you'll return periodically.
• **Cancel state voter registration**. The Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA) lets you vote from abroad using your last US address, but doing so anchors you to that state. Many expats deliberately stop voting to avoid creating this tie.
• **Re-register vehicles** out of state or sell them before leaving.
• **Update professional licenses**. If you hold a state-issued professional license (attorney, CPA, medical), move it to inactive status or transfer it.

Housing

• **Don't keep a home in the state** if you can avoid it. If you do, rent it out at arm's length with a written lease. An empty home you can return to at any time is strong evidence of retained domicile.
• **Establish a foreign residence** with a long-term lease or purchase. Short-term Airbnb stays don't establish domicile abroad.

Financial

• **Change your mailing address** on all accounts, including IRS records (use [Form 8822](https://www.irs.gov/forms-pubs/about-form-8822)) and the Social Security Administration.
• **Move bank accounts** out of the state, or close state-based accounts in favor of national banks with international services (Schwab, Charles Schwab International, HSBC).
• **Update beneficiaries and estate documents** to reflect your new jurisdiction.

Tax Filings

• **File a part-year or final resident return** in your departure year, clearly marked with your move date.
• **File a nonresident return** in subsequent years only if you have state-source income (rental property, business income from the state, etc.).
• **Keep a departure file** with boarding passes, lease agreements, utility bills from your new country, and foreign bank statements. If audited, the burden of proving non-residency often falls on you.

Common Mistakes

**Keeping "just one thing" in the state.** Practitioners routinely see audits triggered by a single in-state item: a storage unit in Sacramento, a Virginia driver's license "for emergencies," a New Mexico P.O. box for mail. States take these as evidence of intent to return.

**Using family addresses.** Registering your car at your parents' California address or having your mail forwarded to a sibling in Virginia creates the appearance of continued domicile. Use a mail-forwarding service in a no-tax state (Texas, Florida, and South Dakota all have established services popular with full-time travelers) or your foreign address directly.

**Returning too often.** Even without a permanent place of abode, spending months each year visiting family in your former state raises audit risk. California auditors have cited patterns of 60+ day annual visits as evidence against non-resident claims.

**Continuing to earn state-source income.** If you keep consulting for your former California employer as a contractor, you'll owe California tax on that income as non-resident source income — and the FTB will notice.

Action Items Before You Leave

1. **90+ days before departure**: Consult a CPA familiar with expat taxation, particularly one who handles your specific state. Get a written residency analysis.
2. **60 days before departure**: Sell or lease your home. Cancel state voter registration. Move financial accounts.
3. **30 days before departure**: Surrender driver's license (or let it expire). Re-register vehicles. Update IRS address using [Form 8822](https://www.irs.gov/forms-pubs/about-form-8822).
4. **On departure**: Save boarding passes, entry stamps, and any exit documentation. Start a dated log of your foreign residence.
5. **In your departure year**: File a part-year resident return. Mark your move date clearly.
6. **First full year abroad**: File IRS Form 2555 for FEIE if you qualify. File nonresident state return only if you have state-source income.

Foreign Tax Credits and Treaties

Moving abroad doesn't eliminate your federal filing obligation. US citizens must file Form 1040 every year regardless of where they live, as confirmed in [IRS Publication 54](https://www.irs.gov/publications/p54). Depending on your new country, you may also file under a tax treaty and claim Foreign Tax Credits using [Form 1116](https://www.irs.gov/forms-pubs/about-form-1116).

The US has tax treaties with approximately 70 countries, listed on the [IRS treaty page](https://www.irs.gov/businesses/international-businesses/united-states-income-tax-treaties-a-to-z). These treaties generally prevent double taxation but don't override state tax obligations. A Portugal-US treaty provision does nothing to help you with California.

Also note: FBAR filing (FinCEN Form 114) is required if your aggregate foreign financial accounts exceed $10,000 at any point in the year, and FATCA Form 8938 has separate, higher thresholds. These are federal requirements that apply regardless of state residency status.

Conclusion: Next Steps

If you're contemplating a move abroad and currently live in California, New Mexico, South Carolina, or Virginia, the single most valuable action is a pre-departure consultation with a tax professional who handles expat cases — expect to pay $500–$2,000 for a thorough review, which is trivial compared to what an adverse residency determination can cost.

If you're already abroad and haven't formally severed residency, file a final part-year return in your prior state for the year you left, even retroactively if necessary. Start building your documentation file now. The longer the gap between your actual departure and your tax treatment of it, the harder the audit defense becomes.

For specific federal expat tax guidance, start with [IRS Publication 54, Tax Guide for U.S. Citizens and Resident Aliens Abroad](https://www.irs.gov/publications/p54), and [Form 2555 instructions](https://www.irs.gov/forms-pubs/about-form-2555). For state-specific rules, go directly to your state's revenue authority — FTB Publication 1031 for California, Virginia Department of Taxation residency guidance, and so on. Generic advice can't substitute for reading the actual rules that will determine your liability.
