Relocating as a High-Net-Worth Individual: What Should You Consider Before Moving Abroad?
Moving abroad can be an exciting prospect, particularly for individuals who have spent years building a successful business, growing their investments or establishing financial security for their families. A new country may offer greater business opportunities, a different lifestyle or a more suitable environment for managing personal wealth.
However, for high-net-worth individuals, relocating involves considerably more than arranging a property purchase and booking a flight. There are questions around tax residency, existing investments, business interests and how a move might affect family finances. Decisions made before departure can also have consequences long after settling into a new country. With more people reviewing their international options, understanding the financial and practical implications of relocation has become increasingly important.
So, what should you consider before making the move?
Why Are High-Net-Worth Individuals Considering Moving Abroad?
There is no single reason why wealthy individuals decide to relocate. For some, it is about accessing new commercial opportunities. Others may be looking for a different pace of life, greater political stability or a more suitable environment for their families. Tax considerations also play a part. Changes to the UK's tax framework, particularly the abolition of the previous non-domicile regime in April 2025, have encouraged some internationally mobile individuals to reconsider their arrangements.
Destinations such as the UAE, Switzerland, Monaco and Italy attract interest for different reasons. The UAE, for example, offers an established international business environment and does not impose federal personal income tax in the same way as the UK. However, choosing a destination simply because of its tax advantages can lead to problems if other factors are overlooked.
Someone who owns several businesses may need to consider where those companies are managed and how their operations will be affected. An individual with a substantial property portfolio may have ongoing obligations in the UK, even after moving overseas. The decision should therefore be based on the complete financial picture, rather than one particular tax advantage.
How Will Moving Abroad Affect Your UK Tax Residency?
One of the first issues to address is whether you will become non-UK resident for tax purposes. It is a common misconception that leaving the UK automatically brings an end to UK tax residency. In reality, HMRC considers several factors when determining an individual's status.
The Statutory Residence Test takes account of the number of days spent in the UK, accommodation arrangements, employment and personal connections. Depending on your circumstances, you may also qualify for split-year treatment, which allows certain tax years to be divided into UK-resident and non-UK-resident periods. This can be particularly relevant if you are relocating part-way through a tax year.
It is also important to understand that becoming non-UK resident does not necessarily remove every UK tax obligation. Income from UK property, certain UK employment income and other UK-connected activities may remain taxable.
Before departure, you should consider:
- Your current UK tax residency position.
- The date you intend to leave.
- Whether split-year treatment may apply.
- How much time you expect to spend in the UK afterwards.
- Any continuing UK income or business interests.
- Whether temporary non-residence rules could become relevant.
Understanding these matters in advance can help avoid unexpected liabilities.
Choosing the Right Country for Your Financial and Personal Circumstances
The most suitable destination will depend on what you want to achieve through relocation...
The UAE is particularly attractive to entrepreneurs, investors and business owners who value international connectivity and an established expatriate community. Switzerland may appeal to individuals prioritising political stability and access to sophisticated financial services.
Italy and Greece also attract internationally mobile individuals through their lifestyle offering and specific tax arrangements for qualifying new residents. However, tax rates should never be the only deciding factor.
Consider the following before making a commitment:
- Tax treatment: How will your income, dividends, investments and capital gains be taxed?
- Residency requirements: What immigration permissions and physical presence conditions apply?
- Business environment: Can you continue managing your existing business effectively?
- Lifestyle: Does the destination offer suitable accommodation, healthcare and education?
- Long-term plans: Is the country somewhere you would realistically want to live for several years?
- Legal considerations: How will local laws affect property ownership, inheritance and financial arrangements?
It is also important to distinguish between immigration residency and tax residency. Obtaining permission to live in a country does not automatically establish your tax position there.
What Happens to Your Existing Wealth and Investments?
For wealthy individuals, one of the more complicated aspects of relocation is understanding how existing assets will be treated after moving overseas. Property, investment portfolios, company shares and trusts may all have cross-border tax implications. For example, retaining UK rental properties after relocation generally means continuing to meet UK tax reporting obligations. Similarly, selling certain assets while overseas may still create UK tax liabilities.
Business ownership also deserves attention. If you operate a UK company, moving personally does not automatically change the company's tax residency. However, the location of management and control decisions can be relevant.
Inheritance and succession planning should not be forgotten either. Moving to another country may affect how your estate is treated and whether existing wills and wealth structures remain appropriate.
A review should ideally cover:
- UK and overseas property holdings.
- Investment portfolios and company shares.
- Trusts and family wealth arrangements.
- Inheritance tax exposure.
- Existing wills and succession plans.
- Banking and currency arrangements.
- Ongoing financial reporting obligations.
The aim is to ensure your financial arrangements remain suitable after the move.
What About Your Family?
Relocation is rarely a decision that affects only one person. For families, moving overseas can involve changing schools, arranging healthcare and considering how different family members will manage their own residency requirements.
There may also be practical questions about relatives who remain in the UK, particularly where regular visits are expected. These connections can be relevant when assessing UK tax residency. For example, someone who relocates overseas but continues to spend considerable time in the UK with close family members should understand how those arrangements may affect their residence position.
It is worth discussing the practical implications with your family before committing to a move. A destination may look attractive financially, but it also needs to work in everyday life.
When Should You Start Planning Your Relocation?
Ideally, relocation planning should begin six to twelve months before departure. More complicated arrangements may require considerably longer. Starting early allows you to review your existing financial position and identify decisions that may need attention.
A sensible approach includes:
Six to twelve months before departure
- Review your UK tax position.
- Research potential destinations.
- Assess existing investments and business interests.
- Understand overseas residency requirements.
- Seek professional tax advice.
Three to six months before departure
- Review the timing of planned financial transactions.
- Consider whether existing structures need reviewing.
- Organise banking and accommodation arrangements.
- Review family and succession planning requirements
Before and after departure
- Keep accurate records of travel dates.
- Complete relevant HMRC reporting requirements.
- Confirm your tax position in the new country.
- Understand continuing UK tax obligations.
- Establish arrangements for overseas tax compliance.
The exact timetable will depend on your circumstances, but early preparation gives you more time to make informed decisions.
Why Professional Tax Advice Matters
International relocation often involves several areas of expertise, including tax, immigration, legal arrangements and wealth planning. The challenge is making sure that the advice works together. A decision that appears beneficial from an immigration perspective may have different implications for your tax position. Similarly, changing business or investment arrangements before departure could create unexpected consequences.

Our focus is on helping clients understand the implications of relocation and make decisions based on their wider financial circumstances.
Final Thoughts
Relocating abroad can offer valuable opportunities for high-net-worth individuals and their families. However, the benefits depend on making the right decisions before departure. Understanding your tax residency, reviewing existing assets and considering your family's long-term needs should all form part of the process.
There is no single destination or relocation strategy that suits everyone. What matters is finding an arrangement that works financially, professionally and personally. If you are considering leaving the UK, seeking advice early can help you understand the implications before making significant commitments.
