General Investment Account for UK Expats: Tax Rules Explained

A General Investment Account (GIA) holds no tax wrapper. Every dividend, interest payment, and capital gain within it is potentially subject to UK tax in the normal way. Whether you already hold a GIA and want to know how it is taxed where you now live, or you have lost your ISA subscription rights on becoming non-resident and are deciding where to invest next, this page explains how the rules work and the points where the detail can change what you owe, in either direction.

In short

A General Investment Account holds no tax wrapper, so its dividends, interest, and gains are all potentially taxable in the normal way, unlike an ISA or SIPP. Expats often use one because you cannot add to an ISA once non-resident. Non-residents are usually exempt from UK CGT on share disposals, though the temporary non-residence rule is a key exception, and how dividends and gains are reported can change what you ultimately pay, in either direction.

What this involves

A General Investment Account (GIA) is a standard taxable investment account that holds no tax wrapper. There is no sheltering from income tax or capital gains tax: dividends, interest, and gains arising inside a GIA are all potentially subject to UK tax in the normal way, in contrast to an ISA (which shelters income and gains entirely) or a SIPP (which gives upfront tax relief on contributions and defers taxation until drawdown). A GIA carries no annual contribution limit and no statutory residency requirement to open or maintain one, though individual platforms set their own eligibility rules for non-resident customers. The absence of a wrapper means the account is fully transparent for UK tax purposes.

Disregarded income: The HMRC term (per HS300) for UK investment income received by a non-UK resident, including UK dividends, UK bank and building society interest, unit trust income, and National Savings income. Under section 811 ITA 2007, the UK tax charge on disregarded income is restricted to the tax, if any, already deducted at source. The personal allowance cannot be set against disregarded income where this restriction applies. Source: HMRC HS300 Non-residents and investment income (2026).
Annual exempt amount (AEA): The amount of capital gains each individual can make in a tax year without paying capital gains tax. For 2026-27 this is £3,000. Gains above this threshold in the year are charged at the applicable CGT rate. Unused AEA cannot be carried forward. Source: gov.uk Capital Gains Tax rates and allowances (2026-27).
Temporary non-residence: An HMRC rule under which a UK national who leaves the UK, realises gains or income while abroad, and returns within 5 years may be taxed in the UK on those gains or income in the year of return, if they were UK resident for at least 4 of the 7 tax years before departure. Source: HMRC HS278 Temporary non-residents and CGT (2026).
Foreign Income and Gains (FIG) regime: A regime introduced from 6 April 2025 that replaced the remittance basis. Eligible individuals (newly UK-resident following at least 10 consecutive years of non-UK residence) can claim exemption from UK tax on eligible foreign income and gains for up to 4 years. Claiming causes the loss of the personal allowance and the annual exempt amount for CGT. Source: gov.uk FIG regime guidance.
Dividend allowance: A separate annual allowance (£500 for 2026-27, per gov.uk) under which dividend income is not subject to income tax, regardless of the investor's other income. Source: gov.uk Tax on dividends.

See the full detail: how this works

Once a person ceases to be UK resident, they cannot make new subscriptions to a UK ISA (with the exception of Crown employees working overseas and their spouses or civil partners). Their existing ISA remains open and retains UK tax relief on money and investments already held in it. A non-resident who wishes to invest new money into a UK-based account must therefore typically use a GIA, subject to the platform's own eligibility rules for non-residents. Source: gov.uk Individual Savings Accounts: If you move abroad.

For non-residents, UK dividends received in a GIA fall within the HS300 disregarded income rules. The tax charge is restricted to the amount of tax, if any, already deducted at source. Where no tax is deducted at source, there may be no further UK liability on that income, but the individual's full income picture and any applicable double taxation agreement (DTA) must be considered. Importantly, the personal allowance cannot generally be set against disregarded income under the section 811 ITA 2007 restriction. Double taxation agreements between the UK and the country of residence may reduce the effective UK rate on dividends, but relief is not automatic: it must be claimed via Self Assessment. Whether dividend tax rates are those set for basic, higher, or additional rate taxpayers depends on the individual's income position and tax year: rates and allowances are set by HMRC for each tax year, and the drafter notes that rates should be verified from gov.uk/tax-on-dividends for the relevant year before reliance.

For non-residents, the general position is that disposals of shares and investments held in a GIA do not attract UK capital gains tax while the individual remains non-resident. The main exceptions are assets used in a UK trade through a branch or agency, UK residential property (where CGT applies regardless of residence), and the temporary non-residence rules. Under HS278, if a person leaves the UK and returns within 5 years, and was UK resident for at least 4 of the 7 tax years before departure, gains on assets owned before departure that were realised while abroad may be taxed in the year of return to the UK. The remittance basis was abolished from 6 April 2025. The FIG regime replaced it: eligible individuals may claim exemption from UK tax on eligible foreign income and gains for up to 4 tax years, but claiming cancels the personal allowance and the annual exempt amount for that year.

Considerations and trade-offs

A GIA accepts any amount at any time with no annual cap. However, every pound of income and every capital gain is potentially subject to UK tax in the year it arises. Regular trading or income-generating holdings in a GIA produce a cumulative tax liability that erodes net returns relative to a tax-sheltered wrapper.
Non-resident CGT exemption on share disposals is a default position of UK tax law, not a permanent feature. If the individual returns to the UK within 5 years and the temporary non-residence rules apply, gains realised on assets owned before departure may be assessed in the year of return. Planning a large disposal without understanding this risk can produce an unexpected UK tax charge.
UK dividends received in a GIA remain potentially subject to UK income tax even for non-residents, through the disregarded income rules. The personal allowance cannot generally be offset against this income. A double taxation agreement may reduce the effective rate, but relief must be claimed, not assumed.
Each disposal in a GIA is a taxable event for CGT purposes and may need to be reported to HMRC. For internationally diversified portfolios or multi-currency holdings, the record-keeping requirement is significant: acquisition dates, acquisition costs, currency conversion rates at each transaction date, and disposal proceeds must all be tracked accurately.
Currency gains on foreign-currency-denominated assets held in a GIA are themselves potentially chargeable to CGT on disposal. The sterling-equivalent gain reflects both the asset price movement and the exchange rate movement between purchase and sale: both components need to be calculated.
US citizens and US tax residents holding non-US pooled funds (such as non-US ETFs or non-US collective investment schemes) in a GIA may find those holdings classified as Passive Foreign Investment Companies (PFICs) under US tax law, triggering adverse US tax treatment. Individuals with US connections should seek specialist US cross-border tax advice before holding non-US funds in a GIA.

How Pharos can help

1.If you hold or are weighing a GIA, the questions that matter are specific: would a planned disposal be caught by the temporary non-residence rule given when you expect to return to the UK, are the UK dividends in the account being treated correctly under the disregarded income rules, and have the currency gains on any foreign-currency holdings been tracked for CGT reporting? Pharos introduces you to a regulated specialist who works through exactly these questions with people in your position.
2.The introduction takes account of where you live, the nature of your holdings, your likely return-to-UK timeline, and any US connection, so the specialist already has relevant experience with the disregarded income rules, the temporary non-residence trap, and the cross-border CGT reporting you are facing.
3.There is no cost to ask and no obligation. Pharos does not pass your details to anyone without your say-so, does not assess your tax position, gives no advice, and does not benefit from any product outcome.
4.Once an introduction is made, the regulated specialist takes on the engagement under their own authorisation. Pharos stays available if your circumstances change or a different specialism is needed.

Situations where people consider this

UAE-based expat with surplus savings after ISA cap

A UK national who moved to Dubai three years ago held a Stocks and Shares ISA before leaving. Since becoming non-resident, they have been unable to make new contributions. They have surplus savings and want to continue investing in funds and equities. A GIA with a UK platform (where the platform's eligibility rules permit non-residents) accepts unrestricted contributions. UK dividends received in the account would fall within the HS300 disregarded income rules; gains on share disposals would generally not attract UK CGT while they remain non-resident, though the temporary non-residence provisions would be relevant if they returned to the UK within five years. Whether this account structure suits their specific tax, reporting, and currency position is a matter a regulated specialist can assess.

Germany-based expat with UK equity fund income

A UK expat living in Germany holds a GIA containing UK-listed equity funds accumulated before emigrating. The fund pays UK dividends quarterly. Under the UK-Germany double taxation convention, a cap may apply to the UK tax rate on dividends, but relief is not granted automatically: it must be claimed via Self Assessment and coordination with the German tax authorities. The interplay with German capital income rules also requires assessment. Whether treaty relief materially changes the net position depends on individual circumstances that a regulated specialist in cross-border taxation can assess.

Singapore expat returning after 5 years

A UK national who emigrated to Singapore five years ago built up a GIA portfolio of international ETFs during that period. Having been non-resident for over five years, the temporary non-residence rules would not apply to gains made during that entire period if they returned to the UK now. However, they have not tracked the currency gains embedded in foreign-currency-denominated ETF holdings. Any sterling-equivalent gain since purchase needs to be calculated on disposal. The record-keeping complexity and whether any of the ETFs held carry PFIC status under US tax law (if the individual has US connections) are both matters a regulated specialist can review.

Whether any of these fits depends on individual circumstances, which a regulated specialist can assess.

Common questions

Can I open a General Investment Account if I live abroad?

There is no statutory bar on non-UK residents holding a GIA. Whether a specific platform accepts non-resident investors is a commercial decision for each provider. Some UK platforms restrict non-resident accounts for regulatory or compliance reasons. The eligibility conditions for a GIA differ from those for an ISA, which has a statutory residency requirement: only people who are UK resident in the relevant tax year may subscribe to an ISA. Source: gov.uk Individual Savings Accounts: If you move abroad.

Do I pay UK capital gains tax on share disposals in a GIA if I am not UK resident?

Non-residents are generally exempt from UK CGT on disposals of shares and investments held in a GIA. The main exceptions are assets used in a UK trade (through a branch or agency) and the temporary non-residence rules: if you return to the UK within 5 years and meet the residence conditions, gains on assets you owned before leaving may be taxed in the year you return. UK residential property is separately subject to CGT regardless of residence status. Source: HMRC HS278 Temporary non-residents and CGT (2026); gov.uk CGT: what you pay it on.

Do I pay UK tax on dividends in a GIA if I live outside the UK?

UK dividends received by a non-resident are treated as disregarded income under HMRC rules (HS300). The tax charge is restricted to the amount of tax, if any, already deducted at source. The personal allowance cannot generally be set against disregarded income. A double taxation agreement with the country of residence may reduce the effective UK rate on dividends, but relief must be claimed rather than assumed. Source: HMRC HS300 Non-residents and investment income (2026).

Why can I not keep contributing to my ISA once I move abroad?

Once you become non-UK resident, you cannot make new contributions to a UK ISA (except as a Crown employee or their spouse or civil partner). Your existing ISA remains open and keeps its UK tax-free status on existing holdings. A GIA is the typical account used for new investment after that point, subject to the platform's eligibility rules. Source: gov.uk Individual Savings Accounts: If you move abroad.

What are the US-person risks with a GIA holding non-US funds?

US citizens and US tax residents holding non-US pooled funds or ETFs in a GIA may find those holdings classified as Passive Foreign Investment Companies (PFICs) under the US Internal Revenue Code. PFIC ownership triggers adverse US tax treatment: gains recharacterised as ordinary income, an interest charge on deferred tax, and annual IRS Form 8621 filing requirements. US-connected individuals should seek specialist US cross-border tax advice before holding non-US funds in a GIA.
