Can I Hold Investments Abroad While Living in the UK?

One of the biggest headaches when you move to the UK, beyond figuring out where to buy decent tea bags, is undoubtedly sorting out your finances – especially if you’ve got a whole portfolio of investments chilling out back in your home country. It’s a common worry: "Can I keep my hard-earned investments where they are, or does HMRC want a piece of everything?" This guide is here to untangle that knot, walking you through the ins and outs of holding foreign investments while living in the UK, so you can manage your money with confidence and without any nasty surprises.

Understanding UK Tax Residency and Domicile

Before we even dive into specific investment types, you absolutely need to get your head around the concepts of UK tax residency and domicile. These two things dictate how your foreign investments are taxed here, and trust me, they're not always straightforward. Many an expat has gotten caught out thinking they knew the rules, only to find HMRC has a different interpretation.

Determining Your UK Tax Residency Status

Being a tax resident in the UK isn't just about how long you've been here; it's a specific legal status determined by a set of rules known as the Statutory Residence Test (SRT). This test is pretty exhaustive and takes into account various "ties" you have to the UK and other countries.

For instance, if you've spent less than 16 days in the UK in a tax year, you’re usually not a UK tax resident. Sounds simple, right? But it gets complicated quickly. If you spend more than 183 days, you're almost certainly a UK tax resident. The grey area in between involves counting your "ties" – things like having a home in the UK, working here, having family here, or spending more significant time here than in any other country. It's not a matter of simply counting calendar days; it’s about establishing your connections. For many expats, especially in their first and last years in the UK, there might be a period of "split year treatment," where you're treated as a UK tax resident for only part of the tax year. This can be a blessing when it comes to foreign income and gains, but you have to actively claim it. You can learn more about this complex area in our guide on Tax Residency and the Statutory Residence Test in the UK (2027).

Why does this matter for your investments? Because if you are a UK tax resident, the general rule is that you are taxed on your worldwide income and gains. This means income from your foreign investments and any profits you make when you sell them are potentially liable for UK tax.

The Nuance of Domicile and the Remittance Basis

Now, let's talk about domicile. This is a much trickier concept than residency. Your domicile is generally where you consider your permanent home to be, often linked to your country of birth or your father's domicile when you were born. It's a sticky thing and incredibly hard to shake off, even if you’ve lived abroad for decades. Most expats arriving in the UK will be considered "non-domiciled" or "non-doms" for tax purposes, at least initially.

Being non-domiciled opens up a special tax regime called the "remittance basis." For a certain period (up to 15 years, usually), if you are non-domiciled and elect to use the remittance basis, you only pay UK tax on your foreign income and gains if you bring them into the UK. This means if you leave your foreign investment income and gains parked in an overseas bank account, untouched in the UK, you generally won't pay UK tax on them. Sounds amazing, right?

Well, there are some significant catches. Electing for the remittance basis means you lose your personal allowance for income tax and your annual exempt amount for Capital Gains Tax. After you've been a UK tax resident for 7 out of the past 9 tax years, there's also an annual charge that kicks in, starting at £30,000, just for the privilege of using the remittance basis. It’s a complex decision and one you absolutely shouldn't make without professional advice, especially if your foreign investment portfolio is substantial. Many expats find it's only worth it if their foreign income and gains are very high. For more on this, check out our article, Understanding the Remittance Basis for Non-Domiciled Residents in the UK.

Taxation of Foreign Investments in the UK

Assuming you are a UK tax resident and either don't qualify for the remittance basis, or you've decided against it, your foreign investments will generally be taxed much like UK-based investments. However, there are nuances and often double taxation agreements to consider.

Foreign Income (Dividends, Interest, Rental Income)

Any income generated by your foreign investments will typically be subject to UK Income Tax. This includes:

• Dividends: If you hold shares in a foreign company or a foreign-domiciled fund, any dividends you receive will be taxable. The UK has dividend allowances, but anything above that is taxed at specific dividend tax rates, which can be different from regular income tax rates.
• Interest: Interest from foreign bank accounts, bonds, or other debt instruments is usually taxable. This is added to your total income and taxed according to the UK income tax bands.
• Rental Income: If you own property abroad and receive rental income, this must be declared. While you might pay tax in the country where the property is located, you'll still need to report the income to HMRC.

The UK tax system involves various Understanding Income Tax and Tax Bands in the UK (2026). It's crucial to understand how your foreign income fits into these bands. The good news is that the UK has double taxation agreements with many countries. These agreements aim to prevent you from being taxed twice on the same income. You can usually claim a credit for the foreign tax you've already paid against your UK tax liability. However, this isn't automatic, and you'll need to declare both the gross income and the foreign tax paid when you file your UK tax return.

Foreign Capital Gains

When you sell a foreign asset and make a profit, that profit is generally considered a capital gain and will be subject to UK Capital Gains Tax (CGT). This applies to:

• Property: If you sell a foreign property for more than you bought it (after accounting for certain allowable costs like purchase fees, stamp duty equivalent, and improvement works), the gain is taxable in the UK.
• Shares, Funds, and Other Assets: The sale of shares, units in foreign collective investment schemes, or even certain personal assets held abroad, could trigger a capital gains tax liability.

Similar to income tax, you usually have an annual exempt amount for CGT, meaning a certain amount of gain is tax-free each year. Anything above that is taxed at specific CGT rates, which depend on your total income and the type of asset sold. Again, double taxation agreements come into play here, allowing you to offset foreign CGT paid against your UK liability. It’s a complicated area, and getting it wrong can be costly. For a deeper dive into this, consult our guide on Understanding Capital Gains Tax (CGT) in the UK.

Inheritance Tax Implications

It's not just income and gains you need to worry about. UK Inheritance Tax (IHT) is a beast of its own, and it can catch expats off guard. Unlike income tax and CGT, which are primarily based on residency, IHT is linked to your domicile. If you are considered 'domiciled' in the UK for IHT purposes (which can happen even if you're not domiciled for income tax), your worldwide estate could be subject to UK IHT upon your death. Even if you retain your foreign domicile, after being a UK resident for 15 out of the last 20 tax years, you might become 'deemed domiciled' for IHT purposes. This means that for IHT, your foreign assets could also fall under the UK tax net. This is where truly expert advice is invaluable.

Practical Considerations for Managing Foreign Investments

Managing foreign investments from the UK isn't just about understanding the tax rules; it’s about the practicalities of moving money, keeping meticulous records, and knowing when to call in the professionals.

Foreign Exchange and Money Transfers

One of the most immediate challenges is moving money between your foreign investment accounts and your UK bank account. Traditional banks can hit you with less-than-favourable exchange rates and hefty transfer fees. This is where services like Wise (formerly TransferWise) really shine. They offer transparent fees and competitive exchange rates, making it much more cost-effective to transfer funds, whether you’re remitting investment income to the UK or sending money out to top up an overseas account. Using a dedicated platform can save you a significant chunk of money over time. When you need to transfer money, perhaps to pay for your foreign property's maintenance or to receive dividends, platforms like Wise can make the process smoother and cheaper. For more on this, check out our advice on How to Transfer Money Into and Out of the UK as an Expat.

Record Keeping is King

I cannot stress this enough: keep impeccable records of everything. This includes:

• Purchase and Sale Documents: Original contracts, statements, and any associated fees for buying and selling foreign assets.
• Income Statements: Annual statements showing dividends, interest, or rental income received.
• Tax Paid Abroad: Proof of any taxes paid in the foreign country on your income or gains.
• Foreign Exchange Rates: The exchange rates used on the date of transactions, as you'll often need to convert foreign currency figures to GBP for HMRC.
• Correspondence: Any communication with your foreign financial institutions or tax authorities.

HMRC can and will ask for evidence, sometimes years after the fact. Having all your ducks in a row will save you immense stress and potential penalties.

Seeking Professional Financial and Tax Advice

The UK tax system, particularly concerning foreign income and assets, is notoriously complex. While this guide gives you a solid overview, it cannot substitute for personalised advice. Engaging with a specialist tax advisor who understands both UK and international tax law is not just a good idea; for many with significant foreign investments, it's essential.

For example, a company like Taxes for Expats specialises in navigating the intricate tax landscape for individuals living abroad or those who have recently moved. They can help you determine your exact tax residency and domicile status, advise on the remittance basis, ensure you claim all eligible double taxation relief, and correctly file your Self Assessment tax return. Trying to figure out every nuance yourself can lead to costly mistakes. Don't be a hero; get help. You’ll thank yourself later when you’re not staring at confusing HMRC forms at 3 AM.

Navigating Specific Foreign Investment Types

Let’s get into the nitty-gritty of some common foreign investment types and their particular considerations for expats in the UK.

Foreign Property Investments

Owning property abroad is a common scenario for many expats. Whether it's a family home, a holiday rental, or an investment property, its tax treatment in the UK needs careful consideration.

Rental Income and Capital Gains on Overseas Property

If your foreign property generates rental income, this income is taxable in the UK, even if you’ve already paid tax on it in the country where the property is located. As mentioned, you can typically claim foreign tax credit relief on your UK tax return to avoid double taxation.

When you eventually sell that foreign property, any capital gain (the profit you make) is subject to UK Capital Gains Tax. You’ll need to convert all costs (purchase price, sale price, renovation costs, agent fees) into GBP using the exchange rate on the dates of the transactions. Again, any CGT paid in the foreign country can usually be offset against your UK CGT liability.

Mortgage Interest and Expenses

You can usually deduct legitimate expenses related to your foreign rental property from your taxable income in the UK. This includes things like agent fees, maintenance costs, and even mortgage interest, although the rules around mortgage interest relief have changed and are now limited to a basic rate tax credit.

Foreign Shares and Investment Funds

Stocks, shares, and collective investment funds (like mutual funds or ETFs) held abroad are also subject to UK tax rules.

Dividends from Foreign Shares

Dividends received from foreign companies or funds are taxable income. They fall under the UK dividend tax regime, which means you get a dividend allowance, and anything above that is taxed at rates depending on your income tax band. If any foreign tax (withholding tax) has been deducted at source, you can usually claim this as a credit against your UK tax bill thanks to double taxation treaties.

Gains from Selling Foreign Shares

If you sell foreign shares or units in an overseas fund for a profit, these gains are subject to UK Capital Gains Tax. Calculating the gain involves converting the purchase and sale prices to GBP. The annual exempt amount for CGT applies, and again, foreign tax credit relief is generally available if you've paid CGT in the country of origin.

A particular complexity arises with certain "offshore funds" or "non-reporting funds." If your foreign investment fund doesn't have "reporting fund status" with HMRC, then any gains you make when you sell units in that fund can be taxed as "offshore income gains" rather than capital gains. This is a much less favourable tax treatment, as offshore income gains are taxed at your marginal income tax rate, which is often higher than CGT rates. Always check the reporting status of any foreign fund before investing or if you already hold one.

Foreign Pensions and Retirement Savings

Pensions are a whole other kettle of fish, and transferring them or receiving income from them while in the UK requires meticulous planning.

Transferring Foreign Pensions to the UK

It is possible to transfer certain foreign pensions to a Qualified Recognised Overseas Pension Scheme (QROPS) in the UK. However, this is a highly regulated area, and there are strict rules to prevent pension liberation schemes. Incorrect transfers can lead to significant tax penalties. Always seek specialist advice before contemplating a pension transfer. Our guide on Understanding National Insurance, the State Pension and Retirement in the UK might be a good place to start, though foreign pensions are an added layer of complexity.

Receiving Income from Foreign Pensions

If you receive pension income from an overseas pension scheme, this income is taxable in the UK. Again, double taxation agreements will typically ensure you don't pay tax twice, but you will need to declare the income on your Self Assessment tax return. The rules can vary significantly depending on the country the pension originates from and the specific double taxation agreement in place.

Here’s a simplified table outlining the typical UK tax treatment for common foreign investment income/gains, assuming you are a UK tax resident and not using the remittance basis:

Investment Type	UK Tax Treated As	Key Tax Rate(s)	Double Taxation Relief?	Additional Considerations
Foreign Rental Income	Income Tax	Income Tax bands (20%, 40%, 45%)	Yes	Allowable expenses, mortgage interest relief
Foreign Dividends	Dividend Income	Dividend tax rates (8.75%, 33.75%, 39.35%)	Yes	Dividend allowance, withholding tax
Foreign Interest	Income Tax	Income Tax bands (20%, 40%, 45%)	Yes	Personal Savings Allowance
Capital Gains (Property)	Capital Gains Tax	CGT rates (18%/28% for residential property)	Yes	Annual exempt amount, exchange rate fluctuations
Capital Gains (Shares/Funds)	Capital Gains Tax / Offshore Income Gain	CGT rates (10%/20%) or Income Tax rates for non-reporting funds	Yes	Annual exempt amount, non-reporting fund rules, FX impact
Foreign Pension Income	Income Tax	Income Tax bands (20%, 40%, 45%)	Yes	QROPS rules, specific treaty provisions

Note: Tax rates and allowances are subject to change by HMRC. This table provides a general overview.

Your Obligations to HMRC and Filing Your Tax Return

Since foreign investments rarely fall under the Pay As You Earn (PAYE) system (where tax is deducted automatically from your salary), you will almost certainly need to register for and file a Self Assessment tax return. This is how you declare all your income and gains to HMRC.

Registering for Self Assessment

If you've never filed a Self Assessment tax return before, you'll need to register with HMRC. You can do this online, and it's something you should do sooner rather than later, especially if you anticipate having foreign income or gains to declare. The deadlines for registering are usually in October following the end of the tax year (which runs from 6 April to 5 April). HMRC has a comprehensive online service to help you set up a Personal Tax Account, which is your gateway to managing your tax affairs. You can find out more by reading our guide on Filing a Self Assessment Tax Return with HMRC in the UK: The Complete Walkthrough (2027).

Completing Your Tax Return

When filling out your Self Assessment tax return, you’ll need to declare your foreign income and gains in the relevant sections. This typically involves completing the 'Foreign' supplementary pages (SA106). This is where you detail the type of income, the amount received (converted to GBP), and any foreign tax paid that you wish to claim relief for. As discussed, having all your records organised will make this process significantly easier.

If you have both UK and foreign income, the process can feel overwhelming. Many expats opt to use an accountant or a specialist service like Taxes for Expats to ensure everything is filed correctly and that they’re not missing out on any reliefs or allowances. It's a small investment that can save you a lot of grief and money in the long run. Our article on How to File Taxes If You Have Both Foreign and UK Income provides a good overview of what to expect.

In conclusion, yes, you absolutely can hold investments abroad while living in the UK. However, the key is understanding the UK’s complex tax rules, especially regarding residency, domicile, and how different types of income and gains are treated. Meticulous record-keeping and, for most, professional advice are not just recommended – they're essential for a smooth financial life as an expat in the UK.
