The upcoming Autumn Budget carries particular significance. Chancellor Rachel Reeves is under mounting pressure to raise £22 billion — a figure that strongly suggests policy changes may be on the horizon. Unsurprisingly, speculation is building over what the Budget might contain and how those measures could impact expats and international investors alike.
For UK expats and international investors, this Budget represents far more than a domestic event. Many live, work, or invest overseas while maintaining ties to the UK — through property, pensions, or ongoing income. With speculation rife about reforms to property taxes, non-dom rules, inheritance tax, and capital gains, this Budget could reshape how globally mobile Britons and foreign investors interact with the UK tax system.
In this article, we explore what the Autumn Budget could mean for UK expats and international investors, outlining potential policy shifts, the historical trend toward higher taxation, and practical steps to prepare with clarity and confidence.
If you’re concerned about how the upcoming UK Autumn Budget could affect your residency, tax exposure, or investment strategy, now is the time to prepare. Speak with our tax specialists to review your position and build a tailored plan before the rules change.
The Changing UK Fiscal Landscape
The UK government has signalled a more interventionist stance on wealth and overseas income. The narrative is clear: those with “the broadest shoulders” should contribute more. For globally mobile individuals, this could translate into new or expanded taxes targeting wealth held abroad or UK-situs assets.
The Budget is expected to focus on four key areas of relevance to expats and international investors: property taxation, non-dom status reforms, cross-border inheritance rules, and capital gains. Let’s examine each.
1. Property Taxes on Overseas Investors
The UK property market has long attracted expats and global investors seeking stable returns and legal transparency. However, the government’s need for revenue makes property an obvious target.
Possible measures include:
Council Tax Reform: New bands for high-value homes or a shift toward a market-value property levy could increase holding costs for overseas landlords.
Stamp Duty Land Tax (SDLT) Overhaul: The existing 2% non-resident surcharge may be replaced or increased, or a “mansion tax” applied to properties above £500,000.
Capital Gains Tax (CGT) Adjustments: While expats already pay CGT on UK residential property, thresholds and rates could rise, especially for higher-value assets.
Annual Property Wealth Charge: A revived concept from earlier policy discussions, this could impose an annual levy on the UK holdings of non-residents and corporate structures.
For international investors, these changes may erode net yields and alter the calculus of buying versus holding UK assets. As such, reviewing ownership structures and financing terms before Budget Day is essential.
2. National Insurance and Income for Non-Residents
Currently, UK rental income is subject to income tax but not to National Insurance Contributions (NICs). This could change.
If NICs were extended to rental or investment income:
Overseas landlords would face a higher total tax burden, reducing net yields.
Tax reporting via the Making Tax Digital system would simplify HMRC’s monitoring of non-resident landlords.
Expats receiving UK income — such as consulting fees or partnership profits — could see NICs introduced, depending on domicile status.
In short, a broader application of NICs would narrow the tax advantage of remaining non-resident while retaining UK-sourced income.
3. Inheritance Tax (IHT) and Gift Rules
IHT reform has been on the agenda for several years, and the 2025 Budget could finally deliver it. The current 40% rate above the £325,000 threshold already captures many expatriates who retain UK-situs property. But new measures could go further.

Likely considerations include:
Revising the 7-Year Rule: Gifts may need to be made up to 10 years before death to fall outside the estate, reducing flexibility.
Consolidating Gift Exemptions: Current exemptions, such as the “gifts out of surplus income” rule, could be abolished or merged.
Re-defining Domicile and Deemed Domicile: Expats who have lived abroad for years may find themselves still deemed UK-domiciled for IHT if ties remain (property, dependents, or pensions).
Worldwide Estate Exposure: The Budget may align IHT with OECD standards, extending UK tax liability to global assets of long-term residents.
For British nationals abroad — particularly retirees in the UAE, Spain, or Portugal — this raises complex estate-planning questions. Many rely on local succession laws and double-tax treaties, which could be undermined by unilateral UK changes.
4. Reform of the Non-Dom Regime
Perhaps the most politically charged reform area, the non-domiciled (non-dom) system has long allowed wealthy individuals to shelter overseas income from UK taxation. Reeves has already signalled an intention to make it “simpler and fairer”.
Potential options include:
Shortening the Non-Dom Window: Reducing eligibility from 15 to 10 years of UK residence before being taxed on worldwide income.
A Flat-Rate Annual Charge: Replacing the remittance basis with a universal charge for foreign-income exclusion.
Transparency and Disclosure Rules: Greater scrutiny on offshore trusts, companies, and bank accounts linked to UK residents or citizens.
For high-net-worth expats who split time between the UK and abroad, these reforms could mean higher annual costs and administrative complexity.
If you have UK property, investments, or estate ties and are unsure how these potential reforms could affect your position, it’s worth reviewing your strategy now. Speak with an international tax advisor at Global Investments to assess your exposure and prepare for what the upcoming Autumn Budget may bring.
Historical Context: A Steady Drift Toward Global Taxation
The likely direction of the Autumn Budget becomes clearer when viewed against the backdrop of long-term shifts in UK tax and residency rules.
In 2024, the UK’s Autumn Budget introduced the largest tax rises in 30 years — totalling £40 billion — signalling a renewed appetite for revenue-generating reforms.
This followed a broader shift over the past decade, during which HMRC has steadily expanded its reach over non-residents:
The Non-Resident Landlord Scheme (NRLS) was introduced to ensure rental income from UK property was taxed appropriately.
Overseas property ownership registries were established to increase transparency and enforcement.
The Finance Act 2019 extended capital gains tax (CGT) to include all UK property disposals by non-residents, including commercial assets.
The current administration is building on this trajectory, focusing on aligning taxation with “economic presence” — such as property ownership or income generation — rather than relying solely on physical residence.
For globally mobile Britons, this signals a decisive move toward global taxation of wealth, income, and assets linked to the UK.
Practical Steps for UK Expats and International Investors
With uncertainty around the upcoming Budget, now is the time for UK expats and international investors to take stock.
Below are practical steps to help you prepare for potential changes — and ensure your affairs remain tax-efficient, compliant, and resilient.

1. Review Tax Residency and Domicile Status
Determine where you are truly tax-resident and domiciled under UK law. Many expats assume long absence equals non-domicile — yet family, property, or pension ties can preserve deemed domicile. Use formal assessments or statutory residence tests for clarity.
2. Audit UK-Linked Income
Map every stream of UK income: rental profits, dividends, pensions, and trust distributions. Identify what may become liable under a broader NIC or global income inclusion regime.
3. Evaluate Holding Structures
If you hold UK property via offshore companies, trusts, or partnerships, revisit their relevance. Potential anti-avoidance rules may target perceived “enveloping” structures. Transparent ownership could soon be cheaper and simpler than complex offshore vehicles.
4. Refresh Estate and Succession Plans
With IHT reform looming, review wills and gifting strategies. If you intend to pass UK-based assets, consider inter-spousal exemptions, joint ownership structures, or trusts while reliefs remain.
5. Diversify Geographically
Many British nationals are now re-domiciling assets or even themselves to more tax-efficient environments — notably the UAE, where there is no personal income, capital gains, or inheritance tax. By combining residency in a low-tax jurisdiction with careful planning, investors can maintain flexibility while staying compliant.
6. Avoid Reactive Moves
Markets and policy evolve faster than regulation. Avoid liquidating assets or restructuring hastily before the Budget. Instead, model different outcomes, prepare documentation, and seek specialist advice immediately after the Budget’s release.
Why Expats Are Re-Evaluating Their Relationship with the UK
The UK remains a premier global hub — but rising taxes and complexity are driving affluent Britons to diversify globally.

Residency vs. Citizenship: Many retain UK citizenship while living abroad, using overseas residency to reduce their UK tax exposure.
UAE as a Preferred Base: Dubai and Abu Dhabi offer high-quality living, strong infrastructure, and security — with zero income or capital gains tax.
Portfolio Diversification: Expats increasingly split investments between UK property and global equities, US real estate, or UAE freehold holdings.
Family and Legacy Planning: Estate planning now integrates multiple jurisdictions, protecting family wealth from sudden legislative changes in the UK.
The Autumn Budget may accelerate this re-orientation — prompting more Britons to shift their fiscal base abroad or formalise non-resident status.
FAQs About the UK Autumn Budget
Q1: When is the Autumn Budget 2025?
It will be announced on Wednesday, 26 November 2025. Timely awareness matters because measures can take effect immediately or from 6 April 2026, leaving only months to adapt.
Q2: If I live abroad, will the Budget still affect me?
Almost certainly. The UK taxes income and gains arising from UK sources, even for non-residents. Proposed inheritance and domicile reforms could extend this to global assets of long-term expats.
Q3: Can I avoid UK tax by moving abroad now?
Changing residency helps only if managed properly. You must satisfy the Statutory Residence Test and demonstrate genuine relocation. HMRC may still tax income from UK sources or UK-situs property.
Q4: How can I reduce exposure to Inheritance Tax?
Use inter-spousal exemptions, lifetime gifting (while rules remain), or trusts. Some expats also consider offshore life-assurance structures or qualifying non-UK pension schemes (QROPS/QNUPS).
Q5: Should I move my assets to the UAE or elsewhere?
For many, yes — provided relocation is genuine. The UAE offers residency through property or investment, alongside a 0% tax regime. However, coordinate timing, legal residence, and UK exit planning with professional advice.
Conclusion
The upcoming Autumn Budget 2025 is set to be a defining moment for UK expats and international investors. With the Chancellor under pressure to raise significant revenue, the likelihood of changes to property taxation, non-dom rules, inheritance tax, and the treatment of overseas income is higher than at any point in recent years. These measures may narrow long‑standing advantages available to those living abroad while maintaining financial ties to the UK.
For globally mobile Britons, the priority now is preparation rather than prediction. This means clarifying tax residency and domicile status, reviewing cross‑border estate and inheritance structures, and assessing the resilience of UK‑linked assets in the face of potential reforms. Many investors are also considering diversification into more tax‑efficient jurisdictions, such as the UAE, where long-term planning can be structured with far greater certainty.
As the Budget date approaches, no immediate action is required — but awareness and readiness are essential. Monitoring developments and understanding how proposed changes may affect your personal position will ensure you are not caught off guard when new rules are announced.
If you maintain UK property, investments, or estate ties, now is the right time to review your exposure. For tailored guidance, speak with a Global Investments tax specialist to assess your position, map out potential outcomes, and plan with confidence ahead of the Autumn Budget.
