Why financial planning is more complex for US expats
For US citizens and former residents living abroad, financial planning carries a unique set of challenges. Unlike most other countries, the US continues to tax its citizens on their worldwide income regardless of where they live. This creates an extra layer of complexity when managing retirement accounts, structuring investments, and ensuring compliance with international reporting requirements.
From 401k plan decisions to FATCA compliance, from navigating the PFIC regime to mitigating US estate tax exposure, American expatriates face a maze of rules that can have significant financial consequences if left unmanaged.
At Hoxton Wealth, we specialise in helping US-connected individuals make sense of these issues. With decades of experience advising internationally mobile professionals and families, we provide structured, compliant solutions to protect and grow wealth across borders.
No two journeys are the same, but South Africans abroad often share a global mindset. Many of our clients:
-
Relocated to the UAE, UK, Europe, Australia, Asia, or the US for professional or business growth.
-
Continue to hold property, investments, or retirement funds in South Africa.
-
Manage multi-currency income or investments across several markets.
-
Are planning for retirement in another country, or a possible return home.
-
Value trust, transparency, and continuity when it comes to managing their finances internationally.
This blend of ambition, mobility, and cross-border complexity requires a global partner — one who understands both South African structures and the wider international landscape.
-
The Foreign Account Tax Compliance Act (FATCA) requires US citizens and green card holders to report their non-US financial accounts once thresholds are exceeded. Additionally, foreign financial institutions must report on accounts held by US persons.
What this means for expats:
- Annual filing of Form 8938 with the IRS for specified foreign assets.
- FBAR (FinCEN Form 114) filing obligations if aggregate foreign account balances exceed $10,000.
- Non-compliance carries severe penalties, even if unintentional.
Many expats discover too late that their overseas bank or investment accounts fall under FATCA reporting. This can lead to costly remediation. At Hoxton Wealth, we help clients understand these requirements and work alongside tax professionals to ensure ongoing compliance.
Financial planning for South Africans living overseas involves balancing both opportunity and obligation:
-
Residency and financial status: Understanding how your tax and residency status change when living abroad.
-
Managing South African assets: Deciding whether to retain, restructure, or repatriate investments, property, and retirement funds.
-
Multi-currency management: Mitigating the impact of ZAR volatility and planning in stronger global currencies.
-
Relocation and repatriation planning: Ensuring wealth remains accessible and efficiently structured if you move again or return to South Africa.
Each decision has long-term implications. Our planners help clients understand the landscape and align their global wealth with their future goals.
-
Leaving South Africa doesn’t mean leaving your retirement behind. Many expatriates still hold:
-
Retirement annuities (RAs)
-
Preservation funds
-
Employer pensions or provident funds
These can continue to form part of your long-term plan, but they need to be considered alongside your new country’s financial framework. Whether you’re contributing to international pension schemes, investing independently, or building wealth for retirement across borders, the key is coordination.
At Hoxton Wealth, we help South Africans develop a globally aligned retirement strategy — one that balances existing assets with new opportunities, and accounts for mobility, lifestyle, and legacy goals.
-
Living and working internationally often means engaging with multiple tax regimes. Awareness and coordination are critical to ensure your wealth is structured efficiently.
Considerations include:
-
Double Taxation Treaties (DTTs) between South Africa and your host country.
-
How foreign income and offshore investments are treated.
-
Potential exit taxes or reporting obligations when ceasing South African tax residency.
-
The role of professional collaboration ensuring your tax advisers and financial planners work together.
Hoxton Wealth provides holistic financial planning services. We do not provide tax or legal advice but work closely with licensed tax advisers and legal professionals in relevant jurisdictions to ensure coordinated planning.

-
South African estate laws and exchange control implications.
-
Cross-border inheritance structures and potential forced heirship in other jurisdictions.
-
Planning for children or dependants living or studying overseas.
-
Collaborating with legal professionals to support the integration of wills and trusts across jurisdictions
