Introduction - Why Global Mobility Complicates U.S. Retirement and Investment Management
Many U.S. citizens live increasingly international lives. A typical modern career may span multiple countries, multiple employers, and multiple financial systems. As a result, individuals often accumulate:
- one or more 401(k)s from past U.S. employers,
- Traditional IRAs or Roth IRAs,
- foreign pension plans,
- investment accounts in different jurisdictions,
- property or business interests abroad,
- income in multiple currencies.
When life moves across borders, the rules that govern retirement accounts, investment structures, and reporting obligations do not move with you. Instead, U.S. rules continue to apply regardless of where you reside.
This creates questions such as:
- “Can I maintain my 401(k) if I move to another country?”
- “What happens to my IRA if I change residency again?”
- “Can I use foreign investment platforms safely as a U.S. taxpayer?”
- “How do PFIC rules apply?”
- “Does my future retirement country affect how I invest today?”
- “Should I consolidate accounts as I move?”
This guide provides an overview designed to help globally mobile U.S. individuals understand the considerations involved in managing 401(k)s, IRAs, and investments across multiple countries. It is educational only and does not constitute personalised advice.

Understanding the U.S. Framework That Applies Globally
Regardless of where an individual resides, U.S. tax rules continue to apply.
- U.S. citizens must file annual U.S. tax returns
- Worldwide income remains taxable
- Retirement account rules continue unchanged
- Reporting requirements still apply (FBAR, FATCA)
- PFIC rules apply to many foreign funds
- Contributions require specific types of income
- Rollover rules apply regardless of location
International relocation does not change any of these obligations.
This means the suitability of your investment structure depends not only on where you are today, but where you may be in the future.
What Happens to a 401(k) When You Move Between Countries
A U.S. 401(k) remains a U.S. account under U.S. law. Moving abroad does not:
- close the account,
- trigger tax,
- trigger penalties,
- affect investment holdings,
- alter plan rules.
However, certain provider policies may affect account functionality.
Potential provider limitations may include:
- restrictions on making investment changes
- reduced online access for certain foreign IP addresses
- limitations for foreign phone numbers
- restrictions on mailing documents
- requests to maintain a U.S. address
- encouragement to roll into an IRA
- “maintenance-only” mode for foreign residents
These are provider-specific, not IRS requirements.
As individuals relocate to new countries, the availability of online access or investor servicing may change depending on the provider’s policies and compliance obligations.
Managing Multiple 401(k)s Across an International Career
It is common for globally mobile individuals to accumulate:
- a 401(k) from a first U.S. employer,
- another 401(k) from a later U.S. employer,
- a 403(b) or 457 plan,
- additional foreign plans after relocating.
As life becomes more international, individuals often evaluate whether to:
- leave each account where it is,
- move assets into a new employer plan (if applicable),
- or consolidate into a Traditional IRA via direct rollovers.
Considerations may include:
- administrative simplicity,
- the number of providers involved,
- provider restrictions on foreign residents,
- diversification options,
- long-term residency,
- fees,
- the need for consistent reporting.
Important neutral point:
Rollover suitability is not automatic and depends on:
- plan features,
- costs,
- investment choice,
- currency needs,
- retirement goals.

Individuals should evaluate all available options before choosing a rollover.

Managing IRAs When Moving Across Borders
Traditional IRAs and Roth IRAs are governed by U.S. rules, regardless of where the account holder resides.
- You may keep an IRA regardless of where you move
- You may roll a 401(k) into an IRA regardless of location
- Withdrawals continue to follow U.S. rules
- Custodian servicing policies may change by country
- Currency considerations may become more important
- U.S.-domiciled ETFs remain aligned with U.S. reporting rules
Access considerations:
Some IRA custodians may:
- restrict accounts based on residency
- limit trading functionality
- require U.S. phone numbers
- request U.S. addresses
These are custodian-specific policies.
How Future Residency Affects Today’s U.S. Retirement Accounts
Long-term planning is essential for globally mobile individuals.
Retirement account considerations often depend on:
- Where you expect to retire
- Whether that country taxes foreign pension income
- Whether a treaty applies
- Whether local rules tax U.S. investment income
- Whether your spending will be in USD or local currency
- Whether your future country recognises Roth treatment
- Whether the country taxes worldwide income
For example (general themes, not tax advice):
- France, Spain, Italy, Germany
May tax foreign pension withdrawals; treaties vary. - UAE, Qatar, Saudi Arabia, Bahrain
No personal income tax. - UK, Australia, Canada
Treaty provisions differ for pensions, dividends, and capital gains. - Singapore, Hong Kong
Do not tax most personal investment income.
Understanding future residency helps inform how you invest today.
Contribution Eligibility When Moving Between Countries
Contributions to retirement accounts depend on U.S.-taxable earned income and plan eligibility—not residency.
401(k) contributions
Require W-2 wages and U.S. payroll
Foreign employment generally does not qualify
Traditional IRA contributions
Require U.S.-taxable earned income
FEIE-excluded income generally does not count
Roth IRA contributions
Require U.S.-taxable earned income
Subject to income limits
Residency is not the determining factor
Backdoor Roth
Still requires eligible compensation
Pro-rata rules apply
Contribution eligibility often changes as an individual relocates, especially when switching between:
- foreign employment
- U.S. employment
- self-employment abroad
- living in low-tax vs. high-tax countries
- using FEIE vs. FTC
This makes multi-country planning important.
PFIC Considerations for Globally Mobile U.S. Investors
PFIC rules apply to many foreign-domiciled pooled investment vehicles.
These may include:
- UCITS ETFs in Europe
- OEICs in the UK
- Asian mutual funds
- offshore insurance-linked products
- portfolio bonds holding foreign funds
PFIC implications may include:
- additional tax reporting (Form 8621)
- tax treatment that differs from U.S.-domiciled funds
- administrative complexity
Because globally mobile individuals often open accounts in different countries, PFIC awareness is important.
U.S.-domiciled funds in IRAs, Roth IRAs, and 401(k)s do not have PFIC treatment because they follow U.S. tax rules.
Multi-Currency Considerations When Life Moves Across Borders
Globally mobile individuals may:
- earn in one currency,
- invest in USD,
- save in another currency,
- and retire in yet another.
Key considerations include:
- currency of future retirement spending
- FX exposure within portfolios
- whether to hold multi-currency cash
- currency alignment across different jurisdictions
- future contribution, withdrawal, and repatriation needs
A portfolio structured for someone living in Dubai may differ significantly from a portfolio structured for retirement in Europe or North America.
Currency planning is often an integral part of multi-country financial management.
Managing Brokerage Accounts When Moving Across Borders
Brokerage account access may change as a result of:
- custodian policies
- local regulations
- FATCA compliance
- servicing restrictions for foreign residents
Common considerations include:
- Some U.S. brokers restrict trading if you move abroad
- Some custodians accept foreign addresses with limited access
- Some custodians support expats across many countries
- Some foreign platforms may offer investments treated as PFICs
Because brokerage access varies globally, individuals often evaluate custodian compatibility with long-term mobility.

U.S. Retirement Accounts and Multiple Relocations
Many individuals move between:
- UAE → UK → U.S. → Europe → Asia
- Canada → U.S. → Middle East → Europe
- North America → Asia → Middle East → U.S.
At each stage, U.S. retirement accounts remain governed by U.S. rules.
Neutral examples:
- Moving to a high-tax jurisdiction
Local rules may affect pension withdrawals. - Moving to a treaty country
Treaty provisions may affect taxation. - Moving to a no-tax jurisdiction
FEIE may be relevant for earned income. - Moving back to the U.S.
U.S. tax rules apply across all accounts.
Understanding how each move affects multiple income types is part of long-term planning.
