As a UK expatriate residing in Thailand, you can leverage strategic measures to protect your assets and minimise tax liabilities. This guide outlines key strategies, including taking advantage of Thailand’s recent tax changes and utilising offshore investments. As the Labour government is increasing taxes. It might be worth for U.K expats to look at their assets in U.K and assess what options they have.
Autumn Budget 2024: What you need to know as a U.K expat
Chancellor of the Exchequer Rachel Reeves delivered her first Budget today, marking significant milestones, including being the first female Chancellor to do so.
While the projected £40 billion increase in tax revenue is notable, few changes were unexpected due to extensive media coverage leading up to the announcement.
Context and Background
The tax and spending announcements followed an extensive review of the current public finance situation. The previous government left a challenging fiscal legacy, and a substantial financial shortfall was discovered after the July election.
The Chancellor announced a sweeping array of spending initiatives, focusing on infrastructure investments in health, education, social housing, and transportation. These are part of what she described as Labour’s third major effort to reconstruct Britain.
Instead of “fixing the roof while the sun is shining,” the Chancellor plans to “fix the foundations” through consistent investment.
Funding for these large-scale projects will partially come from revised government borrowing rules, a shift from earlier opposition statements.
National Insurance Contributions
The most significant tax-raising measure involves changes to Employers’ National Insurance Contributions. The rate will increase from 13.8% to 15% in April 2025, with the threshold for contributions lowering from £9,100 to £5,000.
This increase has sparked debate regarding its alignment with promises not to raise taxes on working individuals. It is challenging to argue that this change isn’t a direct tax on working people, as it impacts owner-managers and can affect salary increases and pricing as employers adjust to maintain margins.
Inheritance Tax and Capital Gains Tax
Discussions around capital taxes, including inheritance tax (IHT) and capital gains tax (CGT), have been prominent post-election.
The increase in CGT rates was less drastic than anticipated; the higher rate increased from 20% to 24%, with the lower rate rising from 10% to 18%. This brings the lower rate close to the basic income tax rate, contradicting the previous approach of taxing gains on second homes at a higher rate.
Business owners will find some relief in the continuation of Business Asset Disposal Relief, which applies a 10% tax rate on up to £1 million in lifetime gains, though it will increase to 18%. However, carried interest CGT will face a significant rise to 32% in April 2025, eventually falling under income tax and national insurance by April 2026.
IHT thresholds remain fixed at £325,000, or £500,000 under certain conditions, until 2030, with a 40% rate. From April 2027, changes will integrate pension pots into the IHT net and limit agricultural and business property reliefs (APR and BPR).
Impact on Private Schools
The imposition of VAT on private school fees and the removal of business rates relief will proceed in January and April 2025, respectively, with some exemptions for English as a foreign language schools and clarification for nurseries.
Corporate Taxation
The Corporate Tax Roadmap caps the corporation tax rate at 25%, while maintaining full expensing, a £1 million Annual Investment Allowance, and preserving R&D tax reliefs, although hopes for a more generous R&D regime were unmet.
Income Tax and Non-Domicile Regime
No changes to income tax rates or thresholds were announced, allowing fiscal drag to continue until April 2028. From April 2025, the UK non-domicile tax regime will be abolished, replaced by a temporary residence regime, affecting individuals with offshore trusts or non-UK property potentially subject to IHT.
Stamp Duty Land Tax and Tax Avoidance
The ‘second’ properties surcharge will rise to 5% from October 31, 2024. Continued efforts to curb tax avoidance include measures targeting ‘umbrella companies’ and tax avoidance promoters, alongside HMRC investments to enhance systems, efficiency, and compliance.
Offshore Investments
Protection Against Capital Gains Tax (CGT):
- By investing offshore, you can shield your capital gains from UK taxation, especially beneficial given the higher CGT rate of 24%.
- Offshore platforms often provide tax-efficient strategies for managing and growing investments without CGT burdens.
Benefits of Joint Accounts:
- Establish joint accounts with your spouse to ensure the smooth transition of assets, simplifying probate processes.
- Many offshore platforms allow for joint accounts that can automatically transfer to the surviving spouse, reducing legal hurdles and ensuring asset protection.
Leveraging Thailand’s Tax Changes
In 2024, Thailand introduced a tax policy where residents are taxed only on money brought into the country. This allows UK expats to grow their investments offshore without incurring local taxes, enabling potentially tax-free growth.
Additionally, UK expats with a Thai spouse can utilise the gifting tax rule, where they can transfer up to 20 million THB tax-free. Amounts above this are taxed at only 5%, providing an efficient way to manage and transfer wealth.
Inheritance Tax (IHT) Planning
Understanding IHT:
- UK estates over £325,000 can be subject to a 40% inheritance tax.
- Proper structuring is crucial to protect your estate from IHT, preserving more wealth for your heirs.
Strategies to Mitigate IHT:
- Offshore trusts or international life insurance can be used to keep assets outside the UK IHT net.
- Proper estate planning ensures assets can be transferred without incurring IHT, which is invaluable for maintaining your family’s financial legacy.

Under the rules established in the October 2024 Budget (effective April 2025), domicile is replaced by a residence-based system. If you were a UK resident for 20 years before moving to Thailand, you remain in the UK Inheritance Tax (IHT) net on your worldwide assets for 10 years after leaving. However, if you were a resident for a shorter period (e.g., 10–13 years), your “tail” is only 3 years. For expats in Thailand, this makes 2026 a critical year to audit your “long-term resident” status and consider offshore trusts or life insurance wrappers to shield non-UK assets before they fall back into the net.
Thailand now taxes all remitted foreign income earned from January 1, 2024, onwards. However, if you utilise an offshore platform (like an International SIPP or a low-fee custody account) and do not bring those funds into Thailand, they remain untaxed by the Thai Revenue Department (TRD). The “optimisation” strategy for 2026 is to live off “clean capital” (savings earned before 2024) while allowing your post-2024 offshore investments to grow via gross roll-up, only remitting what is absolutely necessary to stay within the lower Thai tax brackets (0% on the first 150,000 THB).
Yes, but it requires careful coordination. Under the DTA, the UK has the primary right to tax UK-sourced rental income. When you remit that income to Thailand, it is technically taxable again in Thailand as foreign income. However, you can claim a Foreign Tax Credit in Thailand for the tax already paid to HMRC. In 2026, with Thai tax enforcement becoming more digital, it is essential to keep your UK tax returns and “Certificate of Overseas Residence” (CoR) ready to avoid being double-taxed on the same pound of profit.
