Key Considerations When Relocating Internationally: Insights from our 40 Years’ Experience

Relocating as a high-net-worth individual (HNWI) is rarely a simple lifestyle decision. It can have implications for how taxation, investments, asset protection and succession are treated across different jurisdictions, depending on individual circumstances and applicable laws. Whether driven by lifestyle, tax planning considerations, business opportunities or long-term legacy planning, international relocation can introduce both opportunity and complexity.

Outcomes will depend on individual circumstances and applicable laws. Without appropriate planning, it may give rise to unintended tax exposure, regulatory challenges and fragmented financial arrangements. With over 40 years of experience supporting internationally mobile clients, a key observation  is that: successful relocation is not about reacting to change; it is about planning for it.

Why HNWIs Are Relocating in 2026

Global wealth is more mobile than ever. Increasingly, HNWIs are choosing to relocate for a combination of financial and lifestyle reasons:

• Tax considerations  – Differences in how jurisdictions treat income, capital gains and inheritance.
• Lifestyle enhancement – Climate, healthcare, education and quality of life
• Political and economic factors – Diversifying geographic risk
• Retirement planning – Maximising income longevity in lower-cost jurisdictions
• Business and investment opportunities – Access to global markets and structures

Popular destinations for UK-based HNWIs include Portugal, Spain, France, Switzerland, the UAE and Monaco—each operating under different legal, tax and regulatory frameworks, which may be relevant depending on individual circumstances.

Relocation Is More Than Residency

One of the most common misconceptions is that relocation is simply about becoming tax resident elsewhere. In reality, your financial life becomes multi-jurisdictional the moment you move.

A successful relocation strategy considers:

• Tax residency vs. domicile status
• Double taxation treaties
• Local tax reporting obligations
• Currency exposure
• Regulatory frameworks for investments and advice

Without proper planning, you may remain exposed to UK taxation while also triggering liabilities in your new country of residence.

The Key Pillars of a Successful HNWI Relocation

1. Pre-Departure Planning

The most valuable planning happens before you leave the UK.

This may involve considerations such as:

• Reviewing asset structures
• Timing disposals to manage capital gains tax
• Assessing inheritance tax exposure

Reviewing how investment structures are treated under different tax regimes. Once you become tax resident in another jurisdiction, your options may become more limited.

---

2. Tax Structuring Across Jurisdictions

Each country applies its own rules to income, capital gains, pensions and inheritance.

For example:

• Some jurisdictions offer favourable tax treatment on foreign income
• Others impose wealth taxes or succession rules
• Pension income may be taxed differently depending on the treaty in place

Understanding how these systems interact can help reduce the risk of double taxation and support more efficient structuring, depending on individual circumstances.

3. Pension and Retirement Planning

For many HNWIs, pensions represent a significant portion of total wealth.

Key considerations include:

• How UK pensions are taxed overseas
• Whether consolidation or restructuring is appropriate
• The suitability of international pension solutions
• Currency and income planning in retirement

Cross-border pension planning requires careful structuring to remain compliant while supporting long-term income needs. Pension treatment varies significantly between jurisdictions and may be subject to local regulation, reporting requirements, and bilateral agreements.

4. Investment Structuring

Your existing investment portfolio may be subject to different regulatory treatment or restrictions in a new jurisdiction.

Considerations include:

• Tax-efficient wrappers recognised locally
• Reporting requirements on offshore assets
• Alignment with local regulations (e.g. EU frameworks)
• Currency diversification

A globally structured, multi-asset portfolio may help manage risk and align with your new environment, depending on individual circumstances.

---

5. Estate and Succession Planning

Relocation can significantly impact how your estate is treated.

This includes:

• Forced heirship rules in certain European jurisdictions
• Changes to inheritance tax exposure
• The interaction between UK domicile rules and overseas residency
• Trust and structuring considerations

Without reviewing your estate plan, there is a risk that your wealth may not be distributed  according to your wishes.

The Risk of Getting It Wrong

Relocation without appropriate planning may increase the risk of:  

• Double taxation on income and gains
• Unexpected inheritance tax liabilities
• Non-compliant investment structures
• Inefficient pension withdrawals
• Fragmented wealth across jurisdictions

For HNWIs, planning considerations may play an important role in supporting long-term wealth preservation.
