US State Tax Residency After Moving Abroad

You might.

Moving abroad does not automatically end US state tax residency.

The answer depends on the rules of the state involved and your facts.

A review should usually consider:

• your last US state of residence
• whether you changed domicile
• whether you kept a home in the state
• whether your spouse or children stayed there
• whether you kept a driving licence
• whether you remained registered to vote
• whether you retained bank accounts or mailing addresses
• whether you kept a business interest
• whether you earned state-source income
• whether you worked remotely
• whether you owned rental property
• whether you spent days back in the state
• whether you filed as resident, part-year resident or nonresident
• whether your move abroad was permanent or temporary
• whether you intended to return

California’s Franchise Tax Board says residency status is significant because it determines what income is taxed by California.

New York’s Tax Department says that before deciding whether a New York State income tax return is required, you first need to determine whether you are a resident, nonresident or part-year resident.

That is the key planning point.

State tax is not one national rule.

It is state by state.

For expats, this matters because a weak state exit can create unexpected tax exposure even after leaving the United States.

State tax planning after moving abroad is mostly about facts, evidence and consistency.

The aim is not simply to say you left.

The aim is to show that the state tax position is supportable.

1. What was your last state of residence?

Start with the state you left.

Some states are more likely to create continuing issues than others.

A review should consider:

• whether the state has an income tax
• whether it uses domicile concepts
• whether it has statutory residence rules
• whether it taxes source income
• whether it has part-year resident filing rules
• whether it has aggressive audit practices
• whether it taxes retirement income
• whether it treats remote work income differently
• whether state forms require specific disclosures
• whether local city tax may also apply

The answer can be very different depending on whether you moved from California, New York, Florida, Texas, Washington, Nevada, New Jersey, Massachusetts or another state.

2. Did you change domicile?

Domicile is usually about your permanent home and where you intend to return.

After moving abroad, a state may still look at indicators such as:

• home ownership
• lease termination
• family location
• personal possessions
• driving licence
• vehicle registration
• voter registration
• professional licences
• bank accounts
• mailing address
• doctors and advisers
• club memberships
• business interests
• school enrolment
• travel pattern
• intent to return
• estate planning documents

No single point usually decides everything.

The pattern matters.

3. Are you resident, nonresident or part-year resident?

A move abroad often creates a part-year position in the year of departure.

You may need to review:

• departure date
• final day in the state
• days spent in the state after departure
• whether you kept a permanent place of abode
• whether your spouse or children remained
• whether income was earned before or after the move
• whether state-source income continued
• whether a final resident return is required
• whether a nonresident return is required later

This is especially important in the first tax year after moving.

4. Do you still have state-source income?

Even if you are no longer resident, a state may still tax income sourced to that state.

This may include:

• rental income from state property
• business income
• partnership income
• S corporation income
• wages sourced to the state
• deferred compensation
• equity compensation
• carried interest
• property sale gains
• royalties
• certain pensions or retirement income depending on state rules

You may still need a state return even if you no longer live there.

5. What about remote work?

Remote work can create state tax issues.

If you work abroad for a US employer, the analysis may involve:

• employer location
• payroll state
• assigned office
• where services are performed
• convenience of employer rules
• local country tax
• treaty issues
• payroll withholding
• double taxation relief
• state sourcing rules
• employment contract wording

This should be reviewed before assuming that foreign workdays are automatically free from state tax.

6. What evidence supports your move?

A strong state exit is usually documented.

Helpful evidence may include:

• foreign residence visa
• foreign lease or property purchase
• local utility bills
• local tax residence certificate
• local bank accounts
• overseas employment contract
• children’s school enrolment abroad
• cancellation of state driving licence
• voter registration update
• sale or rental of former home
• shipping records
• local insurance
• local professional registrations
• travel logs
• updated estate planning documents
• evidence of intention to remain abroad

The planning point is simple.

State tax residency is often won or lost on evidence.

7. How does state tax affect the wider financial plan?

State tax can affect:

• investment withdrawals
• IRA and 401(k) withdrawals
• Roth conversions
• equity compensation
• rental property
• business sale planning
• estate planning
• cash flow
• foreign tax credits
• tax equalisation arrangements
• relocation timing
• return-to-US planning

A move abroad is not complete from a planning perspective until federal, state, local and foreign country tax exposures have been considered together.

This page is for general information only and does not constitute personalised financial, tax, legal, state tax, domicile, residence, immigration, pension, retirement, investment, estate planning, US tax, local tax or currency advice.

US state tax residency, domicile, part-year residence, nonresident filing, source income, remote work income, property income, business income, retirement account withdrawals, Roth conversions, equity compensation, local city tax, state audits, federal tax, foreign tax, currency and future residence depend on personal circumstances and may change.

State tax rules vary by state and can be highly fact-specific.

US federal tax advice should be taken from a suitably qualified US tax adviser or CPA. State-specific tax advice should be taken from a qualified adviser familiar with the relevant state.

Local tax, legal, pension and estate planning advice should also be taken where relevant.

Financial planning should be coordinated with federal tax, state tax, local tax, legal, investment, retirement and estate planning advice where appropriate.

Do not assume that moving abroad, obtaining a foreign visa, filing a federal return from abroad or relinquishing a green card automatically ends state tax exposure.

Investing involves risk. Investment and retirement account values can fall as well as rise, and you may get back less than you invest.

Currency movements can affect investments, pensions, retirement accounts, property, tax liabilities and future spending.
