Higher taxes on UK property and savings income, changes to business disposals and increased scrutiny of offshore wealth are reshaping the UK’s investment environment. For international families, entrepreneurs and family offices, the latest Budget reinforces the importance of looking beyond individual assets to the wider international wealth strategy.
The UK’s Budget, announced on 28 October 2026, introduces further changes affecting property investors, entrepreneurs and internationally connected families.
For overseas investors, the announcements come at a time when the UK’s position as a global center for private wealth is already undergoing significant change.
Following the abolition of the longstanding non-domiciled tax regime in April 2025, the latest measures add another layer of complexity for families with UK property, investment income, business interests and international structures.
The UK remains a major financial and investment center. However, understanding the consequences of holding assets there has become increasingly important.
For international families, the question is no longer simply where to invest, but how investments, residence and succession arrangements interact across jurisdictions.
1. UK Property Investment: Higher Taxes, More Planning
One of the most relevant Budget announcements for international investors concerns the taxation of property income.
From 6 April 2027, the announced rates on taxable property income in England, Wales and Northern Ireland will rise to:
- 24% at the basic rate.
- 44% at the higher rate.
- 49% at the additional rate.
These rates concern individuals and other taxpayers within the relevant income tax rules, rather than constituting a general increase in Corporation Tax for property companies.
For internationally connected families holding UK residential or commercial rental properties, the changes could affect net investment returns.
The Budget also develops the previously announced High Value Council Tax Surcharge on residential properties in England valued at £2 million or more, due to begin in April 2028, including further details of relief and deferral arrangements.
For overseas families with substantial London property holdings, these measures make it important to reassess ownership costs, expected rental income and long-term investment objectives.
However, moving a property into a company or another structure is not necessarily advantageous. Transaction taxes, financing arrangements, annual charges and future disposal costs must all be considered.
2. International Wealth Faces Greater Transparency
Another important aspect of the Budget is the government’s increasing focus on tax compliance involving wealthy taxpayers and overseas assets.
HMRC has published plans to strengthen compliance relating to high-net-worth individuals, alongside further work on offshore penalties and the collection of third-party property income information.
The Budget also anticipates the automatic international exchange of certain real estate information from 2029–30.
For families with assets across multiple jurisdictions, this reflects a wider international trend towards greater transparency.
Holding investments through overseas companies, trusts or other arrangements does not necessarily remove tax or disclosure obligations in the jurisdictions concerned.
International investors should therefore ensure that ownership records, income reporting and relevant tax filings remain consistent across their structures.
Effective wealth planning increasingly depends on transparency, appropriate governance and coordinated professional advice, not simply on the jurisdiction in which assets are held.
3. Entrepreneurs and Business Owners: New Opportunities and Restrictions
The Budget also contains important changes affecting entrepreneurs and business succession.
From 6 April 2027, the lifetime gains limit for Business Asset Disposal Relief will decrease from £1 million to £500,000.
At the same time, the government is proposing a new Founders’ Relief, offering a 10% Capital Gains Tax rate on up to £10 million of qualifying lifetime gains for eligible founders of certain high-growth, innovative businesses.
The final conditions remain subject to consultation.
For internationally connected entrepreneurs with UK business interests, these changes could influence the timing and structure of future disposals.
They may also affect wider decisions about business ownership, reinvestment and the transfer of wealth between generations.
However, eligibility cannot be assumed simply because an individual founded or owns a business.
Any proposed transaction should be assessed under the applicable rules, including the tax consequences in the entrepreneur’s country of residence.
4. Why International Residence and Succession Planning Matter
The latest Budget should also be viewed against the wider changes to UK taxation introduced in April 2025.
The replacement of the remittance basis with a residence-based regime for foreign income and gains, alongside changes to the Inheritance Tax treatment of overseas assets, has materially altered the planning environment for certain internationally mobile individuals.
For families with connections to the UK, these rules may influence decisions about residence, investment ownership and future succession.
Each situation can produce different tax and succession consequences.
The appropriate response is not necessarily relocation or restructuring, but a clear understanding of how the relevant jurisdictions interact.
5. The Growing Importance of International Family Office Coordination
As tax systems evolve, internationally connected families face increasing administrative and governance challenges.
A family may have advisors in London, banks in Switzerland, operating businesses in Asia and investment structures in the UAE.
Without effective coordination, changes in legislation can create inconsistencies in tax reporting, ownership records, financial administration and succession arrangements.
A coordinated family office framework can help bring these elements together.
Depending on the family’s circumstances, this may include consolidated reporting, administration of corporate structures, coordination between professional advisors, governance and oversight of succession arrangements.
Not every family requires a standalone family office.
For many, a coordinated or outsourced arrangement can provide the necessary support while avoiding unnecessary complexity.
6. What Should International Investors Consider Now?
The UK Budget 2026 provides an opportunity for international investors and families to review their existing arrangements before the announced changes take effect.
Particular attention should be given to:
- UK property holdings: Assess future rental returns, ownership costs and potential tax exposure.
- International structures: Review companies, trusts and other arrangements holding UK assets.
- Residence and succession: Consider how UK connections interact with the family’s wider international circumstances.
- Business investments: Reassess planned disposals, ownership changes and potential reliefs.
- Family office governance: Ensure ownership records, reporting and advisor responsibilities are properly coordinated.
The objective should be to identify genuine planning opportunities, manage relevant risks and ensure that structures remain appropriate as circumstances change.
Looking Beyond the UK Budget
The latest announcements reflect a wider development in international private wealth.
Tax authorities are increasing scrutiny of cross-border assets, while wealthy families continue to diversify their personal and commercial interests internationally.
For investors in Hong Kong, Singapore, China, the Middle East and other markets, the UK remains an important jurisdiction for property, business and financial investment.
However, investment decisions must increasingly be considered within a broader international framework.
The most effective international wealth strategies are not built around any single country’s tax rules. They are designed to remain appropriate as legislation, family circumstances and investment priorities evolve.
