Moving to China, Hong Kong or Malaysia?: What Happens to Your Pension, Tax and Investments
Hoxton Blog • Moving to China, Hong Kong or Malaysia?: What Happens to Your Pension, Tax and Investments
China, Hong Kong, and Malaysia sit at very different points on the spectrum of financial complexity for British expatriates.
China combines capital controls with a rule that can eventually bring your worldwide income into scope. Hong Kong runs one of the simplest tax systems in the world, taxing only local-source income and levying no capital gains or inheritance tax at all. Malaysia sits somewhere in between, mostly territorial, but with foreign-sourced income increasingly on the radar, softened for now by a long-running exemption.
Drawing on Hoxton Wealth's 2026 country guides, here's what changes, and what doesn't, for your UK tax position, pension and investments across all three.
Your UK Tax Residency Doesn't End the Day You Leave
Wherever in the world you're headed, the starting point is the same: the UK's Statutory Residence Test (SRT). This looks at the amount of time you spend in the UK, your employment arrangements, family connections and other ongoing ties to the country. Leaving the UK does not automatically make you non-resident, your circumstances during the tax year of departure determine how the rules apply.
Two things are worth reviewing before you go:
- Split-year treatment - In some situations, the tax year of departure can be divided into a UK-resident period and a non-resident period, which may reduce the amount of foreign income and gains subject to UK taxation during that year. The rules are detailed and depend on individual circumstances, so it's worth checking whether they apply to you before leaving.
- Ongoing UK tax obligations - Even after becoming non-resident, certain UK income can remain taxable in the UK. Across all three guides, this consistently includes rental income from UK property, certain pension income, some employment income, and dividends or other investment income, depending on your circumstances.
It's also worth reviewing your National Insurance contribution record before you relocate. Voluntary contributions can help preserve entitlement to UK benefits, including the State Pension, and closing any gaps early supports longer-term retirement planning; this holds true regardless of which of the three countries you're heading to.
Pensions: Ownership Stays, But Local Retirement Systems Enter the Picture
For most British nationals, pensions represent one of their largest long-term assets, and relocating to any of these three destinations doesn't generally affect ownership of your UK pension arrangements. What can change is how those pensions fit into your wider planning - and, in one case, what sits alongside them.
- Existing pensions - Most UK workplace and personal pensions can simply remain where they are, and you can continue managing them from China, Hong Kong or Malaysia alike.
- Accessing benefits - UK pension benefits can generally still be accessed while living in any of the three, subject to UK pension legislation. How withdrawals are taxed depends on your residency status, the relevant UK double taxation agreement, and local tax rules.
- Continuing contributions - Depending on your circumstances, it may still be possible to contribute to UK pension arrangements after you've left, though eligibility and available tax relief depend on your residency status.
- QROPS - Qualifying Recognised Overseas Pension Schemes remain an option in certain circumstances across all three destinations, but overseas transfer charges may apply depending on where the receiving scheme is based and where you're resident. In Hong Kong's guide in particular, the point is made explicitly: a QROPS transfer is not automatically beneficial for everyone, worth remembering wherever you're moving to.
- The Lifetime Allowance change - Since April 2024, the old Lifetime Allowance framework has been replaced with new limits governing tax-free lump sums and death benefits. Anyone with a sizeable pension pot should review how this affects their retirement strategy.
Hong Kong's added layer. Hong Kong is the one destination of the three with a compulsory local retirement scheme: the Mandatory Provident Fund (MPF), into which most employees and employers must both contribute. For anyone new to Hong Kong, it's worth assessing how MPF investment choices complement existing UK pensions and wider retirement assets, rather than treating the MPF as a separate, isolated pot.
ISAs Survive the Move - But What Happens Next Depends Entirely on the Destination
Existing ISAs generally remain open once you become a non-UK resident, and the UK tax advantages continue to apply. In all three guides, the same practical limit applies: you can't pay into an ISA while you're non-resident, so it becomes a frozen (if still tax-efficient) pot rather than an active savings vehicle.
What happens beyond that varies sharply:
- In China, the ISA's UK tax advantages continue, but China's capital controls affect how money moves in and out of the country more broadly - and depending on your residency status, income and gains within an ISA may eventually fall within scope of Chinese taxation once worldwide income becomes relevant (see the Six-Year Rule below).
- In Hong Kong, the ISA's tax advantages are typically retained under UK rules, and it's worth considering how investment income and gains within it may be treated locally, and whether the structure still fits once your tax residency changes.
- In Malaysia, ISA income and gains may be treated differently under Malaysian rules depending on your residency status and how the income is received - again, a useful trigger to check whether the existing structure still works once you become a Malaysian tax resident.
This is a natural moment to review your wider investment structure across all three destinations, tax efficiency across jurisdictions, currency exposure, reporting obligations and how flexible your arrangements are if you move again. Some internationally mobile individuals consider offshore investment structures as part of this review, though suitability always comes down to residency, taxation, accessibility and long-term goals.
How the Local Tax Systems Actually Work
This is where China, Hong Kong and Malaysia genuinely diverge.
China
You become Chinese tax resident if you spend 183 days or more in China during a calendar year. The defining feature of China's system for expatriates is the Six-Year Rule: foreign nationals who remain tax resident in China for six consecutive years, without a qualifying break involving an absence of at least 30 consecutive days, may become subject to Chinese taxation on worldwide income from the seventh year onwards. China also operates comprehensive capital controls that regulate the movement of money into and out of the country, affecting international transfers, investment funding and long-term planning more broadly than tax alone. China may also tax gains from certain asset disposals, including property, depending on asset type, source of gain, residency status and any applicable reliefs or treaties.
Hong Kong
Hong Kong runs a territorial tax system: broadly, tax applies to income arising in or derived from Hong Kong rather than worldwide income. Employment income sourced in Hong Kong is subject to Salaries Tax, with an annual tax return and assessment; whether income counts as Hong Kong-sourced depends on the nature of your employment and where duties are actually performed. Hong Kong currently levies no capital gains tax and no inheritance tax, which creates real planning opportunities for internationally mobile families, but also means more of the planning burden shifts to how other jurisdictions, particularly the UK, treat your assets and estate.
Malaysia
You become a Malaysian tax resident if you spend 183 days or more in Malaysia during a calendar year. Malaysia broadly taxes income arising in or derived from Malaysia, but since 1 January 2022, foreign-sourced income received in Malaysia by tax residents can also fall within the Malaysian tax framework. Exemptions are currently available for many resident individuals, and for individual taxpayers, foreign-sourced income received in Malaysia is currently expected to remain exempt until 31 December 2036, subject to conditions being met. Malaysia does not generally impose capital gains tax on most investment assets and does not currently levy inheritance tax, a genuine simplification, though UK assets remain subject to UK rules regardless.
The common thread
All three highlight the same underlying lesson, even though the mechanics differ completely: the less a destination taxes locally, the more your planning depends on your UK position rather than the local one. Hong Kong's zero rates and Malaysia's exemption window don't remove UK tax exposure, they just mean the UK side of the equation carries more of the weight. China sits at the opposite extreme: its Six-Year Rule and capital controls mean the local system becomes the dominant constraint the longer an assignment runs.
The Practical Side Matters Just as Much as Tax
Across all three guides, the same practical themes recur:
- Estate planning - Relocating is a natural trigger to review your will, beneficiary nominations, Lasting Powers of Attorney, domicile position, and how succession works across jurisdictions, this matters especially in Hong Kong and Malaysia, where the absence of local inheritance tax can create a false sense that nothing needs reviewing.
- Protection planning - Life insurance, income protection and medical cover should all be reassessed before and after the move, including whether existing cover remains valid, still meets your needs, and whether additional international cover is required.
- Currency and remittance - Managing money across sterling and Chinese renminbi, Hong Kong dollars or Malaysian ringgit introduces exchange rate risk and, in China's case, genuine operational complexity due to capital controls. A structured approach reduces uncertainty in all three.
- Banking - Opening local banking facilities is usually one of the first priorities after arrival, and most people retain UK banking relationships alongside it for flexibility.
- Country-specific extras - China requires an understanding of local social insurance requirements; Malaysia has the MM2H long-term residence programme worth assessing where relevant, along with property ownership rules to review before any purchase.
Bringing It Together
Tax residency, pensions, investments, remittance strategy, and estate planning interact differently in each of these three destinations, but they interact everywhere. China asks the most of your planning up front, with capital controls and a ticking Six-Year clock. Hong Kong asks the least of you locally, but that simplicity means your UK position does more of the heavy lifting. Malaysia sits in between, with a currently generous but time-limited exemption on foreign income.
The advice across every one of these guides is consistent: plan before you relocate, not after. Reviewing your UK tax position, pension arrangements, investment structures and estate plans ahead of the move gives you the chance to make informed decisions, rather than discovering years into an assignment that a rule like China's Six-Year threshold, or the end of Malaysia's exemption window, has quietly changed your position.
