How to Invest as an Expat Moving Abroad
Last updated: March 2026
Moving abroad creates unique investment challenges that most financial guides do not address. US citizens remain subject to US tax obligations worldwide, many brokerages restrict accounts for overseas residents, and local tax laws may penalize certain US-based investments. This guide helps you maintain and grow your ETF portfolio while living as an expatriate.

US Tax Obligations for Expats
US citizens and green card holders must file US tax returns regardless of where they live. This includes reporting all worldwide income, foreign bank accounts through FBAR filings, and foreign financial assets through FATCA Form 8938. The penalties for non-compliance are severe, with FBAR penalties alone reaching $10,000 or more per unreported account.
The Foreign Earned Income Exclusion allows you to exclude up to $126,500 of foreign-earned income in 2025 from US taxes if you meet the physical presence or bona fide residence test. However, investment income such as dividends, capital gains, and interest is not covered by this exclusion and remains fully taxable to the US.
Brokerage Account Access From Abroad
Many US brokerages restrict or close accounts when you move overseas. Vanguard, for example, limits trading for expats in certain countries. Fidelity and Schwab are generally more expat-friendly but may restrict certain products. Contact your brokerage before moving to understand their expat policies.
If your brokerage will keep your account open, maintain a US mailing address with a trusted family member for correspondence. Do not open local brokerage accounts and invest in foreign mutual funds as a US person. Foreign funds are classified as Passive Foreign Investment Companies and are subject to punishing US tax treatment that can exceed 50 percent of gains.
The PFIC Problem and How to Avoid It
Passive Foreign Investment Companies include most non-US mutual funds and ETFs. For US taxpayers, PFIC gains are taxed at the highest marginal rate plus an interest charge, regardless of your actual tax bracket. This makes investing in local foreign funds extremely tax-inefficient for Americans.
The solution is simple: continue investing in US-domiciled ETFs through your US brokerage account. VTI, VOO, VXUS, and BND are all US-domiciled and do not trigger PFIC rules. Avoid any fund domiciled in Ireland, Luxembourg, or other foreign jurisdictions, even if it tracks the same index as a US fund.
Managing Currency Risk
As an expat, you earn income in a foreign currency but may have US dollar-denominated investments and future obligations. Currency fluctuations can help or hurt you. If the dollar strengthens against your local currency, your US investments gain purchasing power locally. If the dollar weakens, they lose local value.
Most financial planners recommend not hedging currency risk for long-term investors because currency movements tend to balance out over decades. Keep your US investments in US dollars and maintain a local emergency fund in your country's currency to cover near-term expenses. This natural split provides some protection against extreme currency movements in either direction.
Retirement Accounts and Tax Treaty Benefits
Continue contributing to your US retirement accounts if you have US-source earned income. If you work for a US company abroad or have self-employment income, you can still contribute to a 401(k), IRA, or Solo 401(k). If all your income is excluded under the Foreign Earned Income Exclusion, you may not have qualifying income for IRA contributions.
Some countries have tax treaties with the US that recognize retirement account tax deferral. In these countries, your 401(k) and IRA growth is not taxed locally. However, other countries may tax your US retirement account gains annually. Check the specific tax treaty between the US and your country of residence, and consider working with a cross-border tax specialist.

Action Steps
Contact your brokerage before moving
Confirm your accounts will remain open and functional from your destination country. Switch brokerages if needed to Schwab or Fidelity.
Establish a US mailing address
Keep a US address on file with your brokerage through a family member or mail forwarding service. Some brokerages require this.
Never invest in foreign mutual funds
As a US taxpayer, foreign funds are classified as PFICs with punitive tax treatment. Invest only in US-domiciled ETFs.
Set up FBAR and FATCA compliance
File FBAR annually if your combined foreign accounts exceed $10,000 at any point during the year. File Form 8938 with your tax return for qualifying foreign assets.
Hire a cross-border tax specialist
Expat tax situations are complex. A specialist who understands both US obligations and your country's tax laws can save you thousands in avoided mistakes.
Maintain a local emergency fund
Keep three to six months of expenses in local currency in a local bank account for immediate needs without currency conversion.
Frequently Asked Questions
Do I still need to file US taxes as an expat?
Yes. US citizens and green card holders must file US tax returns reporting worldwide income regardless of where they live. The Foreign Earned Income Exclusion and Foreign Tax Credit can reduce or eliminate US tax on foreign-earned income, but you must still file.
Can I keep my US brokerage account while living abroad?
It depends on the brokerage and your destination country. Fidelity and Schwab are generally more expat-friendly. Contact your brokerage before moving. Never hide your overseas address, as this can result in account closure and compliance issues.
What is a PFIC and why should I avoid them?
A Passive Foreign Investment Company includes most non-US mutual funds and ETFs. US taxpayers who own PFICs face punitive taxation at the highest marginal rate plus interest charges. Avoid this by investing only in US-domiciled ETFs like VTI, VOO, and VXUS.
Should I invest in my new country's stock market?
As a US taxpayer, invest through US-domiciled ETFs only. VXUS already includes your new country's stocks without PFIC complications. If you want to invest locally, consult a cross-border tax advisor first.
