Do expats have to pay state taxes? State rules for Americans abroad

For the 2025 tax year, living abroad does not by itself create or end a state filing duty. You may stop resident taxation after a valid domicile change, but a former state can still tax state-source income or require a part-year return under its own rules.

US citizens and resident aliens abroad generally report worldwide income under federal rules. The IRS’s foreign-income filing guidance does not decide state residency.

So, do expats pay state taxes? They do when a state still treats them as residents or taxes income sourced there. A valid move can end resident taxation, but the result depends on the former state’s law. They may owe federal, state, foreign, or more than one tax depending on their facts. Filing a US federal return does not by itself mean a state return is required.

The following 3 outcomes cover the usual state-filing patterns after a move abroad:

• No state filing: residency ended, and no taxable state-source income remains.
• Part-year filing: residency ended during 2025, so the move year is split.
• Resident or nonresident filing: residency continued, or taxable state-source income remained.

For a broader comparison, see TFX’s state taxes and American expats guide.

If you live overseas, do you pay state taxes? Not solely because you live overseas. The former state looks at residency, domicile, and state-source income rather than using the federal expat rules as its test.

Based on our client scenario at TFX: a New York resident leaves on July 1, 2025, and establishes a permanent home abroad. The move can require a 2025 part-year return, with post-move New York-source income still potentially taxable.

Federal filing continues separately. TFX’s US expat taxes guide explains why citizenship or resident-alien status can keep Form 1040 filing in place after a move.

Who must pay state taxes while living abroad

For 2025, state tax exposure usually turns on 3 questions: were you still a resident, did you have income sourced to the state, and did you move during the year? Your answer can lead to no return, a part-year return, or a resident or nonresident return.

For expat state taxes, residency and state-source income are the main state-level signals. Federal filing is separate under the IRS abroad-filer reminder.

For 2025, residency status and state-source income usually determine whether a state return is required.

 

Do expats pay state income tax? Yes when the state’s residency or sourcing rules create liability. A person can owe no state income tax after a clean exit but still need a return to claim a refund or report state-source income.

The following 4 yes-or-no checks narrow the filing question:

1. Were you still a resident? If yes, check the resident-return rules.
2. Did you have state-source income? If yes, check nonresident filing thresholds.
3. Did residency end during 2025? If yes, check the part-year return.
4. Do none of those triggers apply? If yes, a state income-tax return may not be required.

TFX’s guide on whether an expat needs to file gives federal context for the separate Form 1040 question.

Takeaway: If you answer “yes” to residency, state-source income, or a 2025 move-year trigger, check the former state’s current return instructions before deciding not to file.

If you are still considered a resident

If your former state still treats you as a resident for 2025, it can tax income beyond that state, subject to its own law and available credits. No universal 183-day rule applies: New York, Virginia, California, and other states use different domicile or statutory-residency tests.

The following 5 clues can support a state’s claim that your old domicile or residency continued:

• A home remains available to you in the state.
• Your driver’s license or vehicle registration stays there.
• Your voter registration still points to the state.
• A spouse or close family remains in the former home.
• You keep using the state address for important records.

Red flag: Passing the 330-day federal physical presence test does not end state residency.

Compare the bona fide residence and physical presence tests with your state’s separate rules. The IRS’s FAQ for US citizens and resident aliens abroad addresses federal obligations. It does not establish or terminate state domicile.

 

 

Based on our client scenario at TFX: one taxpayer sells the former home, changes official records, and establishes a permanent foreign home in 2025. Another keeps the home, license, and family address; the second file is harder to defend as nonresident.

If you earn income from a state

Even after you become a nonresident in 2025, income tied to your former state can still trigger tax or filing. Common examples include rent from in-state real estate, business or partnership income sourced there, and wages for services physically performed in the state.

The IRS treats rent as federal income, and its rental income and expense guidance explains the federal reporting side. State sourcing is separate.

For a 2025 nonresident, property and work physically connected to a state are common filing triggers.

 

The following 3 items often do not become state-source income merely because you once lived in the state:

• Foreign wages for services performed entirely abroad, subject to special state sourcing rules.
• Foreign investment income with no state property or business connection.
• Retirement income received as a nonresident when 4 USC §114 protects it from the former state.

A nonresident can still owe state tax when taxable state-source income remains. A rental property is a common reason a person living abroad still files.

Based on our client scenario at TFX: a taxpayer moves to Spain in 2025 but keeps a rental condo in California. The foreign salary may fall outside California sourcing after residency ends, while the California rental remains a state filing issue.

See how rental property is reported on a US tax return.

For the expat angle, see how US expats handle tax on rental income.

What counts as state-sourced income

For a nonresident in 2025, state-sourced income is income a state can connect to activity or property within its borders under that state’s law. Real estate, in-state work, business activity, and pass-through income are common triggers, while foreign wages for work abroad usually are not.

For nonresidents, the strongest 2025 source connection is usually where property, services, or business activity is located.

 

The following 3 items are usually not state-source after residency ends, unless a specific state rule says otherwise:

• Wages for services performed entirely outside the state.
• Interest or dividends with no special state business connection.
• Qualifying retirement income protected from nonresident state taxation by federal law.

Do I owe state income tax if I live abroad? The answer turns on residency and source, not distance. A taxpayer with no former-state residency and no taxable state-source income can have no state income-tax return for that state.

If you moved abroad mid-year (part-year residency)

A move abroad during 2025 can create a part-year state return because you were resident for only part of the tax year. States commonly tax income received while you were resident, then apply nonresident sourcing rules after your residency ends, but allocation methods and thresholds differ.

The following 3 points create a practical move-year timeline:

1. Before departure: treat income under the state’s resident rules.
2. Departure date: document when domicile and residence facts changed.
3. After departure: apply nonresident sourcing rules to income that remains connected to the state.

The following 4 records help support the date your 2025 move became real:

• Lease termination, home sale, or new foreign lease.
• Final utility bills or service cancellations.
• Passport stamps, boarding records, and travel logs.
• New address, license, or other official records where available.

TFX’s five things to know before moving abroad can help organize pre-departure records.

Based on our client scenario at TFX: a taxpayer leaves Illinois on June 30, 2025 and establishes a foreign domicile on July 1. Illinois can tax resident-period income plus Illinois-source income received after the move under its part-year rules.

How to determine your state tax residency as an expat

State residency for 2025 depends on your former state’s rules, not on a single federal test. Start with 4 issues: domicile, intent to leave, days physically present, and continuing ties. A foreign address alone does not prove that your prior state residency ended.

Use this 4-step decision tree for a 2025 state-residency review:

1. Domicile: Did you establish a permanent home outside the former state?
2. Intent: Do your actions show that the move is indefinite rather than temporary?
3. Presence: Did you cross a state-specific day threshold?
4. Lingering ties: Is a home, license, voter record, family tie, or address still active?

A country of domicile versus residence comparison helps separate your permanent-home concept from where you happen to be physically present.

US taxes living abroad – no US address, expat tax requirements: having no US mailing address does not itself end state domicile. States look at the full record, so use your former state’s tests rather than treating an overseas address as conclusive.

The following 4 documents can strengthen a nonresident position:

• Proof that the former lease ended or home was sold or genuinely rented.
• Voter registration changes or overseas-voting records.
• A new license or identification record where legally available.
• Bank, insurance, tax, and account records showing the new address.

TFX’s guide on how to become an expat covers the broader relocation process.

Residency check: If you answered yes to a former-state home, high day count, active official ties, or an intent to return permanently, you may still be a resident under that state’s law.

The most and least expat-friendly states

For tax year 2025, state treatment ranges from no broad individual income tax to detailed domicile and statutory-residency tests. The practical difference is not a label like “friendly” or “sticky” by itself, but whether the state still treats you as resident or taxes your in-state income.

For 2025, the useful comparison is whether a state taxes broad personal income, how it tests residency, and what it taxes after you become nonresident.

 

TFX’s states without income tax guide gives more context on the first group.

No-income-tax status does not erase property tax, business registration, entity tax, withholding, or special-income rules. A person can have a state obligation without owing a broad individual tax on foreign wages.

California is a useful example of why the former state matters. See TFX’s discussion of whether expats can leave California for tax purposes.

States with no personal income tax

For tax year 2025, 8 states impose no individual income tax, while Washington does not tax wages but does tax certain long-term capital gains. These 9 states are commonly grouped as states without broad wage income taxes, but business, property, or special-income obligations can still apply.

The following 9 states had no broad wage income tax for the 2025 tax year:

• Alaska: no personal state income tax; no individual income-tax return if no other filing trigger applies.
• Florida: no personal income tax; individuals have no personal income-tax filing requirement.
• Nevada: no individual wage-income tax; check business or other Nevada tax duties separately.
• New Hampshire: the interest-and-dividends tax was repealed for periods beginning January 1, 2025.
• South Dakota: no individual state income tax; property or business obligations can still apply.
• Tennessee: the Hall income tax has been repealed for tax periods beginning January 1, 2021.
• Texas: no personal income tax; business franchise-tax duties are separate.
• Washington: no wage tax for 2025, but its long-term capital-gains tax can apply.
• Wyoming: no individual income-tax program; state revenue administration covers other tax types.

Washington requires extra care. For tax year 2025, its capital-gains tax uses 7% and 9.9% tiers after applicable deductions. A 2026 law creates a 9.9% tax on income above $1 million beginning January 1, 2028, so it does not affect 2025 returns.

The following 3 situations can still create state obligations in this group:

• You own or operate a business subject to state business taxes or filings.
• You own real property that creates property, rental, or transaction obligations.
• You receive income covered by a special tax, such as Washington capital gains.

For older deduction context, TFX explains why taxpayers should not rush to prepay property or state taxes.

States that usually let you leave cleanly

For 2025, Arizona, Illinois, Oregon, and Colorado use source-based rules for nonresidents after residency ends. None promises a “clean exit,” so prove the domicile change and track property, work, business, and pass-through income that remains tied to the state afterward.

Official state guidance confirms nonresident source-income rules in all 4 states.

The following 5 actions create a cleaner record when leaving Arizona, Illinois, Oregon, Colorado, or another state that applies nonresident source rules after residency ends:

• Change your driver’s license or identification when legally required.
• Update voter registration or overseas-voting records.
• Establish a new domicile outside the former state.
• Reduce the former state’s housing and personal footprint.
• Retain dated proof of departure and the new home.

The TFX moving abroad checklist can help coordinate these records with other relocation tasks.

Good documentation matters because “easy to leave” is not a legal category. If a state questions your exit, the issue is whether your facts satisfy its residency law, not whether the state is commonly described as expat-friendly.

The toughest states for expats

Four states deserve extra attention in 2025 because residency rules use different domicile tests, day counts, or safe harbors. California, New York, Virginia, and New Mexico each apply distinct tests, so your evidence must match the state rule rather than one national checklist.

Official state guidance confirms the 4 different residency tests summarized below.

These 4 states merit closer 2025 recordkeeping because each uses a distinct residency or physical-presence test.

 

California’s 546-day rule is not a universal expatriate safe harbor. TFX explains the conditions in its California safe-harbor guide for working expats.

The following 4 records are especially useful if a state challenges your exit:

• Contemporaneous day-by-day travel records.
• Home sale, lease termination, or long-term rental documents.
• New foreign housing and employment records.
• Official address, license, and voter-registration changes.

Do expats need to file state taxes for past years?

Past-year filing turns on 3 questions for each open year: did residency continue, did state-source income remain, and was a part-year return missed? IRS Streamlined Filing Compliance Procedures cover federal offshore compliance only; they do not file, settle, or erase state income-tax obligations.

The IRS Streamlined Filing Compliance Procedures require federal certifications and returns for eligible taxpayers. They do not create a state amnesty or state filing program.

Do US citizens living abroad need to file state taxes? For past years, they need to check each state year separately. A missed resident, part-year, or nonresident filing can remain open under the former state’s rules.

The following 3 steps organize a past-year review:

• Identify every year in which residency or state-source income may have continued.
• Gather move records, old state returns, W-2s, K-1s, rental records, and withholding forms.
• Compare each year with that state’s filing threshold, statute rules, and available relief.

Based on our client scenario at TFX: a taxpayer left Virginia in 2022 but kept Virginia domicile facts through 2024. Back returns may be needed. A taxpayer who ended residency cleanly and had no Virginia-source income after 2022 can have a different result.

See TFX’s guide to filing back taxes for multiple years. If the issue extends beyond state returns, TFX also explains when an expat may need help filing back taxes.

How to change your state residency before moving abroad

A state residency change is easiest when your 2025 facts show one clear departure date and a new home elsewhere. No single action ends domicile in every state, so coordinate housing, identification, voter records, mailing addresses, family location, and day-count records around the same move.

The following 3 stages make the change easier to document:

Before departure, complete the following 4 tasks:

1. Decide the intended permanent move date.
2. End or restructure the former residence.
3. Plan where official mail and records will go.
4. Review the former state’s domicile and day-count rules.

On departure day, complete the following 3 tasks:

1. Save travel evidence and the final occupancy date.
2. Record when employment or business activity moved.
3. Keep the first proof of your new foreign residence.

After departure, complete the following 4 tasks:

1. Update licenses or identification when required.
2. Update voter registration or overseas-voting status.
3. Change bank, insurance, payroll, and mailing records.
4. Track return visits and any state-source income.

Based on our client scenario at TFX: a clean file has one consistent 2025 move date across housing, travel, payroll, and official records. A messy file has several competing dates and keeps the former home available indefinitely.

How to properly sever ties with your state

Properly severing state ties in 2025 means building consistent evidence that your former state is no longer your permanent home. Selling a house or changing a license helps, but no 1 step guarantees nonresident status because states weigh domicile, presence, intent, and other facts differently.

The following 6 steps strengthen a claim that your former state is no longer your domicile:

1. End, sell, or genuinely rent the former residence.
2. Change the driver’s license and vehicle records when required.
3. Update voter registration or overseas-voting records.
4. Align banking and insurance addresses with the new home.
5. Use a consistent foreign or valid mailing address.
6. Track days spent back in the former state.

If you need a stable mailing solution abroad, compare TFX’s virtual mailbox options for expats.

The following 5 document types are worth retaining if residency is later questioned:

• Closing statements, leases, and utility records.
• Passport, boarding, and travel records.
• Foreign residence permits and local registrations.
• License, voter, banking, and insurance changes.
• State returns and correspondence showing the position taken.

These actions strengthen a nonresident position; they do not guarantee it. A state can weigh the entire record, and a retained house or repeated long visits can carry more weight than one changed address.

State tax planning before and after moving abroad

State tax work is easier when it starts before the 2025 departure date and continues after the move. Use 3 phases: document your exit before leaving, update records immediately afterward, and keep tracking state-source income and days in the state for later returns or residency questions.

Before departure, complete the following 4 tasks:

1. Review the former state’s domicile and statutory-residency rules.
2. Choose and document a defensible move date.
3. Decide what will happen to the former home.
4. Identify rental, business, K-1, or other state-source income that will continue.

TFX’s year-end financial planning tips for expats can help coordinate tax records before the calendar year closes.

Immediately after departure, complete the following 4 tasks:

1. Update official addresses and identification.
2. Save the new foreign lease, deed, visa, or residence permit.
3. Change payroll and employer location records where accurate.
4. Start a day-count log for return trips.

For ongoing maintenance, complete the following 3 tasks:

1. Track state-source income by property, work location, or entity.
2. Keep evidence showing where your permanent home remains.
3. Review the former state’s rules before filing each year.

Keep the following 5 record groups for the long term:

1. The core documents proving the original move date.
2. Sale, lease, or rental records for the former home.
3. Foreign housing and residence documents.
4. Travel logs for years with close day-count questions.
5. Filed resident, part-year, and nonresident state returns.

How federal expat tax benefits impact state returns

Federal expat benefits do not automatically settle a 2025 state return. The FEIE is claimed on Form 2555, and the Foreign Tax Credit is usually claimed on Form 1116, but each state decides how federal income adjustments or foreign tax credits affect state tax.

The IRS requires Form 2555 with Form 1040 or Form 1040-X to claim the FEIE. For tax year 2025, the maximum FEIE is $130,000 for a qualifying individual.

Federal benefits can reduce federal tax, but they do not by themselves change state domicile or the source of income.

 

TFX’s Foreign Earned Income Exclusion guide explains the federal eligibility tests.

State conformity varies. Do not assume a federal exclusion removes state income, and do not assume a federal Foreign Tax Credit creates the same credit on a state return.

Before choosing a federal method, compare our guide to Foreign Tax Credit and FEIE.

State tax rules for special expat situations

Special 2025 situations change the state analysis because income source, work location, and residency can point in different directions. Remote employees, self-employed workers, retirees, students, landlords, and part-year movers should match each income stream to the state rule that applies.

The following 6 situations deserve separate 2025 review because the filing risk comes from different facts:

• Self-employed expats: state risk can follow work performed in-state or a business still operating there. Keep work-location, entity, and client records.
• Remote employees: states can source wages by physical work location, while New York has a separate convenience-of-employer rule. Keep employer-office and workday records.
• Retirees: 4 USC §114 generally protects qualifying retirement income from a former state once you are a nonresident. Keep proof that residency ended.
• Students: a temporary foreign study period may not prove domicile changed. Keep school, housing, family-home, and travel records.
• Rental-property owners: property in the former state can keep producing state-source income. Keep leases, expense records, and sale documents.
• Part-year movers: the move date can split resident and nonresident periods. Keep dated housing, payroll, and travel evidence.

For business owners and freelancers, TFX’s tax tips for self-employed expats cover the federal side of working abroad.

The IRS’s rental real estate recordkeeping guidance explains federal income and deduction records that also support the underlying rental facts.

Special cases need state-by-state review because source rules can change by income type. A New York remote-work rule, a California rental, and Virginia domicile are 3 different legal questions.

Is the federal expat filing deadline the same as the state deadline?

No. For 2025 federal returns filed in 2026, qualifying taxpayers abroad received an automatic federal filing extension to June 15, 2026, while state deadlines differ. As of August 19, 2026, several original deadlines have passed, but valid state or federal extension periods may still be open.

The IRS explains extensions for US citizens and resident aliens abroad. An extension to file does not necessarily stop interest on tax due.

For 2025 returns filed in 2026, the federal June 15 overseas rule does not create one uniform state deadline.

 

California, New York, Virginia, and South Carolina each use different 2026 timing for 2025 returns. Confirm the state rule rather than assuming the federal extension controls.

 

 

TFX’s foreign-country tax filing deadline guide helps coordinate host-country dates with US filings.

TFX also has a historical state filing-deadline archive, but its dated content should not be used as the source for 2026 deadlines.

When and how to get professional help

Professional help is most useful before you file or amend a 2025 state return when residency or sourcing is genuinely unclear. Five common triggers are a sticky-state dispute, missed prior returns, rental income, a mid-year move, or conflicting evidence about where your domicile changed.

The following 5 situations are strong reasons to get a state-specific review before filing or amending:

• Your former state disputes when residency ended.
• You have unfiled resident, part-year, or nonresident returns.
• You kept rental property or a business interest in the state.
• Your 2025 move split income between resident and nonresident periods.
• Your housing, license, family, and travel records point to different domiciles.

If you are deciding whether paid help is warranted, see TFX’s guide on when to hire an expat tax professional.

The following 4 record groups make a review more useful:

• Exact move dates and travel history.
• Prior state returns and state notices.
• Licenses, voter records, housing records, and address changes.
• W-2s, 1099s, K-1s, rental statements, and withholding records.

A federal balance can have separate causes. TFX lists 10 reasons US expats may owe federal tax for that separate analysis.
