Moving abroad doesn't end your state tax bill. California, New York, and Virginia can keep taxing your worldwide income for years after you leave.
Most American expats know they still owe federal taxes to the IRS. What blindsides them is the state return (and the back tax bill) that shows up years later from a state they thought they'd left behind.
The problem? Each state has its own residency rules, and some are designed to make it extremely difficult to stop filing. These are the "sticky states." If you lived in one before moving abroad, you may still owe state income tax on every dollar you earn overseas.
In this guide, we'll break down which states keep taxing expats, how to properly sever residency, and what happens if you don't.
| The Core Issue | Moving abroad does not automatically end state tax obligations. You must actively break residency |
| Stickiest States | California, New York, Virginia, South Carolina, New Mexico, with aggressive residency rules and audit enforcement |
| No-Income-Tax States | Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming. If you last lived here, no state return needed |
| Burden of Proof | On you. The taxpayer must prove they changed domicile, not the other way around |
| Common Triggers | Keeping a driver's license, owning property, maintaining a bank account, voter registration, dependents in state |
| FEIE & State Taxes | Most states do not recognize the Federal Foreign Earned Income Exclusion. You owe state tax on income the IRS excluded |
| Penalties | Back taxes + interest + failure-to-file penalties, potentially spanning every year abroad |
Why Moving Abroad Doesn't End State Taxes
At the federal level, the rules are clear: every U.S. citizen and Green Card holder files a federal return regardless of where they live. The IRS doesn't care that you moved to Barcelona. You file a 1040 every year.
State tax works differently. States tax based on residency, and each state defines residency on its own terms. Some states make it easy to leave. Others make it nearly impossible, at least on paper.
The critical distinction is between domicile and statutory residency:
- Domicile is your permanent, legal home, the place you intend to return to. You can only have one domicile at a time. Most states presume you keep your domicile until you affirmatively establish a new one.
- Statutory residency is based on physical presence, typically spending 183+ days in a state during the tax year, often combined with maintaining a "permanent place of abode."
For expats, domicile is where the fight happens. You may be living in London for three years, but if California still considers you domiciled there, you owe California tax on your worldwide income, including your UK salary.

The 9 No-Income-Tax States (You're in the Clear)
If you last lived in one of these states before moving abroad, you can skip this article. You have no state income tax return to worry about:
- Alaska
- Florida
- Nevada
- New Hampshire (taxes interest and dividends only through 2024, fully repealed starting 2025)
- South Dakota
- Tennessee
- Texas
- Washington
- Wyoming
Strategy note: Some expats establish residency in a no-income-tax state before moving abroad, specifically to sever ties with a sticky state. This is a legitimate tax planning strategy, but it must be done properly (see "How to Break State Residency" below).
The Sticky States: Who Keeps Taxing Expats
A "sticky state" is one where the combination of aggressive residency definitions, audit enforcement, and domicile presumptions makes it difficult to stop filing after you move abroad. Here are the worst offenders.
California: The Stickiest State in the Country
California's Franchise Tax Board (FTB) is notoriously aggressive about maintaining residency claims on former residents. California uses a facts-and-circumstances test with no bright-line rule for domicile, meaning there's no single action that definitively ends your residency.
What California looks at (the "closest connections" test):
- Where is your family (spouse, children)?
- Do you own or maintain a home in California?
- Where are your bank accounts, financial advisors, and accountants?
- Do you still have a California driver's license?
- Where are you registered to vote?
- Where do you have professional licenses?
- Where are your personal belongings (furniture, clothing, pets)?
- Where are your social ties (club memberships, religious organizations)?
The safe harbor rule: California has a "safe harbor" for temporary absences: if you leave California under an employment-related contract for at least 546 consecutive days, you are considered a nonresident during the contract period, even if you maintain a California home. But this applies to employment contracts only, not self-employment, and you cannot spend more than 45 days in California during any taxable year within the contract period.
What makes California so sticky:
- The FTB actively audits former residents, especially high earners
- Owning California real estate, even a rental property, is treated as a strong residency tie
- Your spouse or children remaining in California can anchor your domicile
- California's top marginal rate is 13.3% (the highest in the nation), so the stakes are enormous
- The FTB has been known to investigate social media, credit card records, and cell phone location data
New York: Domicile + Statutory Residency Double Trap
New York has two independent paths to taxing you, and either one is sufficient:
Path 1, Domicile: If New York was your domicile and you haven't established a new one elsewhere, you remain a New York domiciliary and owe tax on all income. Like California, New York uses a facts-and-circumstances analysis: where is your "permanent place of abode," where is your family, where do you vote, where are your bank accounts, where do professional and business affiliations connect you?
Path 2, Statutory residency: Even if you've changed your domicile to another country, New York will still tax you as a resident if you (a) maintain a "permanent place of abode" in New York and (b) spend more than 183 days in the state during the tax year. A "permanent place of abode" includes an apartment you own or maintain, even if someone else lives there. A home you own but leave empty may still count.
What makes New York sticky:
- New York's combined state + city tax rate can reach 10.9% (state) + 3.876% (NYC) = over 14.7%
- Maintaining any residential property in New York, even an investment property that's "available" to you, can trigger the permanent place of abode test
- New York auditors are particularly focused on "day counts." They track travel records, E-ZPass usage, and credit card transactions
- Part-year residency doesn't eliminate the obligation. New York taxes you as a resident for the portion of the year you were domiciled there
Virginia: The Quiet Sticky State
Virginia gets less attention than California and New York, but its residency rules are surprisingly aggressive for expats.
Domicile-based taxation: Virginia taxes anyone domiciled in the state on their worldwide income. Like other sticky states, Virginia presumes you maintain your domicile until you affirmatively establish a new one. Simply living abroad isn't enough.
What makes Virginia sticky:
- Virginia does not have a statutory residency test like New York. It's purely domicile-based, which means even zero days spent in VA can still result in full-year tax liability if you're considered domiciled there
- Heavy military and government contractor population means the state is experienced at taxing people who live out-of-state or overseas
- Virginia's top rate is 5.75% (on income above $17,000), so while lower than CA/NY, it applies from a very low threshold
- Many D.C.-area expats (State Department, diplomatic, NGO workers) get caught assuming their overseas posting automatically changed their domicile
South Carolina & New Mexico: Other States That Hold On
South Carolina considers you a resident if you are domiciled in the state or if you maintain a permanent place of abode and spend more than 183 days in the state. SC's top rate is 6.2% (2026). What makes it sticky is its broad interpretation of domicile and the fact that retirees who maintain vacation homes rarely think about formally changing domicile.
New Mexico taxes residents on worldwide income and defines residency broadly. A domiciliary is anyone who lives in the state "not for a temporary purpose." NM's top rate is 5.9%. The state is particularly aggressive with part-year residents and has limited administrative guidance for expats, making it harder to establish that you've left.

State-by-State Comparison: How Sticky States Tax Expats
| State | Top Rate | Residency Test | Stickiness Factor | FEIE Recognized? |
|---|---|---|---|---|
| California | 13.3% | Domicile (facts & circumstances) | Very High. FTB audits aggressively | No |
| New York | 10.9% (+ 3.876% NYC) | Domicile OR 183 days + abode | Very High. Dual tests, active audits | No |
| Virginia | 5.75% | Domicile only | High. No safe harbor, low threshold | No |
| South Carolina | 6.2% | Domicile OR 183 days + abode | Moderate. Less audit enforcement | No |
| New Mexico | 5.9% | Domicile (broad definition) | Moderate. Limited expat guidance | No |
| Connecticut | 6.99% | Domicile OR 183 days + abode | Moderate. Similar to NY structure | No |
Do States Recognize the Foreign Earned Income Exclusion (FEIE)?
This is the question that causes the most sticker shock for expats: most sticky states do not recognize the federal FEIE.
Here's what that means in practice. On your federal return, you may exclude up to $132,900 (2026 threshold) of foreign earned income using Form 2555 (FEIE). This can reduce your federal taxable income dramatically, in many cases to zero.
But California, New York, Virginia, and most other sticky states start their tax calculation from federal gross income before the FEIE is applied. So even if you owe $0 to the IRS, you could owe $10,000+ to California on the same income.
Example: Sarah, a software engineer, moves from San Francisco to Berlin. She earns $120,000 in Germany. On her federal return, she excludes the full $120,000 using the FEIE and owes no federal tax. But California doesn't recognize the FEIE. The full $120,000 is subject to California's income tax. At California's marginal rates, she owes roughly $8,500 to the FTB despite owing nothing to the IRS.
This is why breaking state residency before moving abroad is so critical. The combination of a sticky state that doesn't recognize the FEIE can result in a higher effective tax rate than if you'd stayed in the U.S.

State Filing Deadlines for Expats: Don't Assume June 15 Applies
At the federal level, U.S. citizens and residents living abroad get an automatic extension to June 15 to file their 1040 (with a further extension to October 15 available by filing Form 4868).
States do not automatically follow this rule.
- California: The filing deadline is April 15. The FTB does not recognize the federal June 15 automatic extension for overseas filers. You must file Form 3519 (or FTB's extension form) separately if you need more time.
- New York: Filing deadline is April 15. New York grants an automatic 6-month extension to October 15 if you file Form IT-370, but the extension is for filing only, not for payment. Estimated tax is still due April 15.
- Virginia: Filing deadline is May 1 (Virginia gives residents slightly more time than most states). An automatic 6-month extension to November 1 is available if you file Form 760IP, but again, payment is due by May 1.
The trap: Many expats file their federal return by June 15 or October 15 and completely forget about the state deadline. By the time they realize the state return was due in April, they've already incurred late-filing penalties and interest.
How to Break State Residency Before Moving Abroad
The single most important thing you can do to avoid years of unnecessary state taxes is to formally sever residency ties before you leave the country. The burden of proof is on you, the taxpayer, to demonstrate that you've abandoned your domicile.
Here's the playbook:
1. Surrender your state driver's license. This is the most-cited residency tie in state audits. Don't just let it expire. Actively surrender it and obtain identification from your new country (or from a no-income-tax state if you're transitioning through one).
2. Change your voter registration. De-register from your state. If you want to continue voting in U.S. elections, register via the Federal Post Card Application (FPCA) for overseas voting. This does not establish state residency for tax purposes in most states.
3. Sell or vacate your home. Maintaining a residence that's "available to you" is a primary audit trigger in every sticky state. If you own property:
- Best option: Sell it before departing
- Acceptable: Rent it out under a long-term lease (12+ months) to unrelated tenants. This usually converts it from a "permanent place of abode" to an investment property
- Risky: Leaving it vacant or with family members. States treat this as maintaining a home
4. Close or relocate bank accounts. Move your primary banking relationship out of the state. A checking account at a California bank is evidence of continuing ties.
5. Update your address everywhere. Employer records, investment accounts, insurance policies, subscriptions, professional licenses, alumni associations. Anything that lists your address should reflect your new location.
6. File a part-year return for the year of departure. Report income through your departure date as a resident, and income after your departure date as a nonresident. This creates a clear record of when you claim residency ended.
7. Keep a paper trail. Document everything: lease for your new home abroad, flight records, proof of foreign utility accounts, foreign bank account opening, foreign employer contract. If the state audits you in three years, you'll need this evidence.
For self-employed expats, breaking residency is even more critical. See our Self-Employed Expat Tax Guide (coming soon) for entity structure strategies that can reduce state exposure.
What Happens If You Don't File State Returns While Abroad
Ignoring state filing obligations doesn't make them go away. Here's what happens:
Penalties accumulate silently. Most states impose both a failure-to-file penalty (typically 5% of unpaid tax per month, up to 25%) and interest on unpaid balances. These compound for every year you don't file.
States can file a return for you. California and New York both have "substitute for return" (SFR) programs. The state estimates your income (usually higher than reality), calculates the tax, and sends you a bill. You then have to prove the amount is wrong.
There's no statute of limitations if you don't file. In most states, the statute of limitations for assessment doesn't begin until a return is filed. If you never file a California return, the FTB can come after you indefinitely, similar to the IRS's rule for unfiled federal information returns like Form 5472.
It gets harder to resolve over time. Catching up on one missed year is manageable. Catching up on seven years of unfiled returns, with penalties and interest stacking on each, can result in five- or six-figure bills. Many expats only discover the problem when they try to refinance a U.S. property, apply for a mortgage, or return to the U.S. and find tax liens.
State Taxes and the Foreign Tax Credit
While most states don't recognize the FEIE, many do allow a credit for taxes paid to a foreign country, similar to the federal Foreign Tax Credit (FTC).
This is important because if you're living in a high-tax country (Germany, France, UK, Japan), the foreign taxes you pay may fully offset your state tax liability, even in states that don't recognize the FEIE.
How it works:
- California: Allows a credit for taxes paid to a foreign country on Form 540, Schedule S. However, the credit is limited to the California tax attributable to the foreign-source income.
- New York: Allows a resident credit for taxes paid to foreign countries on Form IT-112-R, similar to how it credits taxes paid to other U.S. states.
- Virginia: Allows a credit for income taxes paid to foreign countries on Schedule CR.
Strategy: If you live in a country with a higher tax rate than your state (for example, Germany's top rate of 45% vs. California's 13.3%), the foreign tax credit may eliminate your state tax entirely. This is one reason some CPAs recommend the FTC over the FEIE for expats in high-tax countries who are stuck with a sticky state. The FTC generates credits that can offset both federal and state tax, while the FEIE only helps at the federal level.

The "Establish Residency in a No-Tax State" Strategy
One of the most common strategies expats use before moving abroad: establish domicile in a no-income-tax state before departing.
Here's how it works:
- Before moving overseas, you relocate from California (or New York, Virginia, etc.) to Florida, Texas, or another no-income-tax state
- You establish genuine ties: rent an apartment, get a driver's license, register to vote, open bank accounts, update your address on all financial accounts
- You file a part-year return in your old state showing the residency change
- Then you move abroad, with Florida (or Texas, etc.) as your last state of residency
Does it work? Yes, but only if it's done genuinely. State tax authorities, especially California's FTB, will scrutinize "flag stops" in no-tax states. If you lived in Florida for two weeks before flying to London, that's not a genuine domicile change. Most CPAs recommend spending at least 3-6 months establishing real ties in the new state before departing internationally.
Requirements for this strategy to hold up under audit:
- Physical presence in the new state for a meaningful period
- Genuine ties: lease, utility bills, driver's license, voter registration
- Complete severance of ties with the old state (sell/rent your home, surrender driver's license, etc.)
- Filing a part-year return in the old state and no return in the new no-tax state
FBAR and State Taxes: Separate Obligations
A common point of confusion: FBAR (FinCEN 114) is a federal filing requirement with FinCEN. It has nothing to do with state taxes. However, expats who have foreign bank accounts above $10,000 need to file the FBAR separately from both their federal and state returns.
Similarly, FATCA reporting (Form 8938) is a federal requirement that accompanies your 1040. States don't have their own version of FATCA, but the information reported on federal returns, including foreign income, is shared with state tax authorities through data-matching programs.
This means: If you file a federal return reporting $120,000 in foreign earned income but don't file a California return, the FTB's automated matching system will likely flag the discrepancy and send you a notice.

State Taxes for Expats
State tax obligations don't end at the border. If you lived in California, New York, Virginia, or another sticky state before moving abroad, your state likely still considers you a resident and expects a return every year.
The cost of getting this wrong is steep: years of back taxes, penalties, and interest that can dwarf your federal tax bill. But with proper planning, the fix is straightforward:
- Sever ties completely before you leave: driver's license, voter registration, property, bank accounts
- File a part-year return for the year of departure
- Use the Foreign Tax Credit strategically if you can't break residency immediately
- Don't assume silence means compliance. States can come after you years later
- Work with a CPA who understands both federal and state international tax obligations
