Introduction - Understanding the Realities of Investing as a U.S. Expat

When Americans relocate overseas, they often find that the investment landscape changes meaningfully. Local banks and investment platforms may offer products that are common within their own jurisdictions but treated differently under U.S. tax law. Likewise, U.S.-based brokerage firms may apply additional servicing rules for individuals living outside the United States.

Most U.S. citizens abroad continue to face questions such as:

  • Which accounts can I still use from overseas?
  • Why do some platforms limit access after I move?
  • How do I avoid U.S. tax complications when investing overseas?
  • What is a PFIC and does it apply to my situation?
  • How do future residency plans affect long-term investment decisions?
  • Can I still invest in U.S.-domiciled ETFs while living abroad?

This guide provides an overview of the considerations relevant to U.S. citizens investing while living overseas. It is general educational information, not personalised advice. Individual circumstances - including country of residence, tax position, future plans, and risk tolerance - determine the most suitable approach.

What This Guide Helps You Understand

This guide provides U.S. expats with an overview of how investing changes when living overseas. After reading, you will understand:

  • Why U.S. tax rules continue to apply regardless of where you live
  • How PFIC rules affect foreign-domiciled funds, platforms, and pooled investments
  • Why some U.S. brokerage firms restrict access for individuals with foreign addresses
  • How to evaluate whether U.S.-domiciled ETFs, mutual funds, or equities remain accessible abroad
  • How future residency plans influence investment decisions
  • How currency exposure impacts long-term financial outcomes
  • Why tax reporting requirements such as FBAR and FATCA continue
  • How global diversification can be achieved without using foreign-domiciled funds
  • How investment planning must align with U.S. tax rules, local rules, and multi-country mobility

This guide is for educational purposes only and does not constitute personalised tax, legal, or investment advice.

What Changes When a U.S. Citizen Invests From Abroad?

Moving abroad does not sever U.S. tax obligations. Americans remain subject to U.S. tax rules regardless of where they live. This creates several cross-border considerations.

1. Certain U.S. Brokerage Firms Limit Services for Foreign Residents

Some U.S. investment platforms may:

  • restrict access to U.S.-listed ETFs for foreign residents
  • limit new account openings for individuals with foreign addresses
  • require U.S.-based phone numbers for account security
  • restrict or close accounts if residency rules change
  • limit trading functionality

These rules vary significantly by custodian and jurisdiction.
They are not IRS requirements; they arise from firm-specific compliance policies.

2. Foreign Investment Funds May Be Treated as PFICs Under U.S. Law

A Passive Foreign Investment Company (PFIC) is generally a non-U.S. corporation meeting certain passive income or passive asset thresholds. Many foreign-domiciled pooled investment vehicles may be classified as PFICs.

Examples include:

  • UCITS ETFs
  • UK OEICs
  • non-U.S. mutual funds
  • certain offshore insurance-linked products
  • foreign-domiciled portfolio bonds
  • pooled funds in local retirement schemes

PFIC classification may result in:

  • additional U.S. tax reporting (Form 8621)
  • tax outcomes that differ from U.S. mutual funds or ETFs
  • administrative complexity

Whether a particular investment is a PFIC depends on its structure and the investor’s elections.
Investors should understand PFIC implications before purchasing foreign-domiciled pooled investments.

3. U.S. Tax Residency Continues Regardless of Where You Live

U.S. citizens and residents must:

  • file annual U.S. tax returns
  • report worldwide income
  • follow U.S. rules on investments, retirement accounts, and reporting (e.g., FATCA)

Therefore, even when living abroad, U.S. individuals often find it simpler to use U.S.-domiciled investment vehicles.

4. Currency Becomes Part of Planning

An individual may:

  • earn in one currency,
  • invest in USD,
  • retire in another currency.

Exchange rates may affect long-term outcomes. Multi-currency planning often becomes part of the investment approach.

5. Future Residency Choices Are a Key Variable

Where an individual plans to retire (or relocate next) may influence:

  • tax treatment of U.S. investment accounts
  • local taxation of dividends or capital gains
  • pension/retirement withdrawal rules
  • estate tax considerations
  • preferred asset allocation
  • currency exposure

Investment planning becomes more effective when future residency is taken into account.

A Framework for How U.S. Expats Can Think About Investing

The following framework provides general considerations.
These are not recommendations, but common themes observed among U.S. citizens investing from overseas.

1. Understand PFIC Exposure Before Buying Foreign Funds

Many foreign mutual funds, ETFs, and pooled investments may fall under PFIC rules.
Because PFIC classification can lead to:

  • additional reporting
  • different tax treatment
  • administrative complexity

…many U.S. expats choose to review foreign-domiciled investment products carefully before purchasing them, unless a tax professional confirms they are appropriate.

This includes products widely used in the UK, Europe, Asia, and Australia.

2. Consider U.S.-Domiciled Investments Where Appropriate

U.S.-domiciled investments often simplify tax reporting and avoid PFIC considerations.

These may include:

  • U.S.-listed ETFs
  • U.S. mutual funds
  • U.S. equities
  • U.S. fixed-income securities
  • diversified portfolios built from U.S.-domiciled holdings

However, access to U.S.-listed ETFs may depend on the custodian’s servicing policies for individuals with foreign addresses. Accessibility varies.

3. Maintain Global Diversification Through U.S.-Domiciled Instruments

Even while avoiding foreign-domiciled funds, investors can achieve global exposure using U.S.-listed ETFs that provide:

  • international developed market exposure
  • emerging market exposure
  • global bonds
  • sector allocation
  • factor-based strategies

This allows for diversification without engaging PFIC rules.

4. Coordinate Investment Planning With Expected Tax Residency

Investment decisions may be influenced by where an individual expects to live in the future.

Examples of considerations:

  • local tax treatment of capital gains
  • treatment of U.S. dividends
  • treatment of withdrawals from U.S. retirement accounts
  • currency needs
  • treaty benefits
  • estate tax implications

Long-term goals should inform investment structure.

5. Consider Multi-Currency Planning

Multi-currency planning may be relevant when:

  • income and expenses occur across several currencies
  • retirement may take place in a different currency zone
  • long-term goals involve cross-border spending

There is no “right” approach. Some may prioritise USD stability; others may prefer exposure closer to retirement currency.

6. Choose Platforms That Support U.S. Expats

Some U.S. custodians have dedicated processes for individuals living abroad. Key considerations include:

  • whether the platform accepts foreign addresses
  • whether U.S.-listed ETFs are accessible
  • availability of online account management
  • reporting formats suitable for U.S. tax requirements
  • beneficiary designations that function internationally

Custodian choice should reflect individual needs and long-term planning.

7. Use a Disciplined, Long-Term Approach

Regardless of jurisdiction, many investors benefit from:

  • staying focused on long-term goals
  • avoiding reactions to short-term market movements
  • maintaining a consistent allocation
  • periodic rebalancing
  • integrating planning with expected residency

This approach may help maintain stability across different market cycles.

Understanding PFIC Considerations in More Detail

PFIC rules exist to align U.S. tax treatment of foreign pooled investments with domestic standards.

Key PFIC considerations:

  • Foreign-domiciled pooled funds may be PFICs
  • PFIC taxation may differ significantly from U.S. long-term capital gains treatment
  • PFICs may require Form 8621
  • Elections (e.g., Mark-to-Market or QEF) may apply
  • Tax implications vary by investment and circumstances

Before purchasing foreign funds, investors may wish to understand whether PFIC rules apply.

U.S.-Domiciled Alternatives to Foreign-Domiciled Funds

U.S.-domiciled funds generally:

  • fall under U.S. tax rules

  • simplify reporting

Examples include:

  • U.S.-listed global equity ETFs
  • U.S.-listed international ETFs
  • U.S.-domiciled emerging markets funds

  • factor-based portfolios
