Financial Glossary: Terms Every International Investor Should Know

100+ definitions covering pensions, tax, investments, trusts and offshore structures

Financial services uses an enormous amount of specialist vocabulary — and the terminology used for international investors, expats and high-net-worth individuals can be particularly dense. This glossary defines over 100 key terms covering UK and international tax, pension schemes, investment structures, insurance products, trusts and regulatory frameworks.

Definitions are written from a UK and internationally mobile perspective. Where a term has different meanings in different jurisdictions, the most relevant distinction is noted. This is a reference resource, not personal advice — tax rules and product terms change frequently, and individual circumstances vary.

A

AIM (Alternative Investment Market): The London Stock Exchange's market for smaller and growth companies, launched in 1995. AIM-listed shares may qualify for Business Property Relief (BPR) after two years' ownership — though from 6 April 2026 AIM shares attract 50% relief rather than the former 100% — making them potentially useful for UK inheritance tax planning. However, AIM companies carry higher risk than main market stocks — liquidity can be limited and valuations volatile.
Annual Allowance (Pension): The maximum amount you can contribute to UK-registered pension schemes in a tax year while still receiving tax relief. For 2026/27 the standard annual allowance is £60,000 (raised from £40,000 in April 2023). Higher earners with adjusted income above £260,000 face a tapered annual allowance that reduces to a minimum of £10,000. Unused allowance can be carried forward from the three previous tax years.
Autocall / Autocallable Note: A structured investment product that automatically matures early if a reference index or basket of shares reaches a specified level on predetermined observation dates. If called, the investor receives their capital back plus a fixed return. If not called, the note continues until maturity, where capital is typically protected unless the underlying has fallen below a barrier level. Popular with cautious investors seeking defined returns above cash.
AUM (Assets Under Management): The total market value of investments managed by a financial institution or adviser on behalf of clients. AUM is used as a measure of firm size and is often the basis for management fee calculations. A higher AUM generally indicates a more established firm, though it should be considered alongside performance, service quality and fee transparency.
AIFMD (Alternative Investment Fund Managers Directive): An EU regulatory framework governing managers of alternative investment funds, including hedge funds, private equity and real estate funds. AIFMD sets requirements for authorisation, risk management, transparency and investor disclosure. Post-Brexit, UK managers operating under the UK AIFMD regime must comply with equivalent FCA rules.

B

Bare Trust: The simplest form of trust, where assets are held by a trustee on behalf of a named beneficiary who has an immediate and absolute right to both the capital and any income. Bare trusts are often used for children (with a parent as trustee) or to hold assets on behalf of someone who lacks legal capacity. The beneficiary is treated as owning the assets directly for tax purposes.
Base Currency: The primary currency in which an investor measures returns, holds cash or reports financial performance. For a UK-based investor the base currency is typically sterling, but internationally mobile individuals and HNW families may use US dollars or euros as their functional base currency. Currency mismatches between base currency and asset currency create foreign exchange risk.
Bearer Bond: A fixed-income security in which the physical holder is presumed to be the owner — there is no registered ownership. Bearer bonds have largely been eliminated in most jurisdictions due to their susceptibility to tax evasion and money laundering. The US phased them out in the 1980s; most EU countries followed. Investors should be wary of any modern bearer instrument.
Beckham Law (Spain): An informal name for Spain's special tax regime for incoming workers (now governed by the Ley de Startups, effective 2023). Qualifying individuals who become Spanish tax residents can elect to be taxed only on Spanish-source income for six years, paying a flat rate of 24% on Spanish employment income up to €600,000. It does not apply to worldwide income as the original Beckham Law did. Conditions apply regarding prior Spanish residence.
Beneficial Ownership: The natural person who ultimately owns or controls an asset or legal entity, even if a nominee, trust or company holds legal title. Beneficial ownership registers are now required in most OECD countries under anti-money-laundering regulations. For international investors, understanding and documenting beneficial ownership is essential for bank account opening and regulatory compliance.
Bond (Fixed Income): A debt instrument through which a borrower (government or corporation) raises capital from investors in exchange for periodic interest payments (the coupon) and repayment of principal at maturity. Bond prices move inversely to interest rates: when rates rise, existing bond prices fall. Government bonds (gilts in the UK, Treasuries in the US) are considered lower risk than corporate bonds.
Buy-to-Let: The purchase of residential property with the intention of renting it out rather than occupying it. In the UK, buy-to-let mortgage interest relief has been progressively restricted since 2017 and replaced by a 20% tax credit. Stamp Duty Land Tax surcharges apply on additional properties. UK rental income is taxable regardless of where the landlord resides.

C

Capital Gains Tax (CGT): A tax on the profit made when selling an asset that has increased in value. In the UK, CGT rates from October 2024 are 18% (basic rate taxpayers) and 24% (higher/additional rate) on most assets; residential property also faces 18%/24%. The annual CGT exempt amount has been reduced substantially — to £3,000 for 2024/25. Non-UK residents disposing of UK property must report and pay any CGT within 60 days of completion.
Capital Protected Note: A structured product designed to return at least the investor's original capital at maturity, while offering the potential for additional returns linked to a market index or basket. Capital protection is typically provided by the creditworthiness of the issuing bank — if the issuer defaults, capital protection may not hold. Early encashment often results in losses.
Carried Interest: A share of the profits allocated to fund managers (especially in private equity and hedge funds) in excess of the capital they contributed. Carried interest is typically 20% of profits above a hurdle rate, and is taxed as a capital gain in many jurisdictions. Its favourable tax treatment relative to income tax has been the subject of ongoing political debate in the UK.
CPI Escalation: An arrangement under which pension income or insurance benefit payments increase each year in line with the Consumer Price Index. CPI escalation is common in defined benefit occupational pensions, providing some protection against inflation. Compare with RPI escalation (usually higher) and fixed-percentage increases.
Critical Yield (DB Pension Transfer): In the context of a defined benefit pension transfer, the critical yield is the investment return that a defined contribution pension fund would need to achieve each year to match the value of the defined benefit pension being given up. If the critical yield is very high (e.g., above 7–8%), the DB pension is typically worth keeping. FCA guidance requires advisers to make this calculation for transfer advice.
CRS (Common Reporting Standard): An OECD standard for the automatic exchange of financial account information between tax authorities worldwide. Over 100 jurisdictions participate. Financial institutions report details of accounts held by non-residents to their local tax authority, which then passes the information to the account holder's country of tax residence. CRS has substantially reduced the scope for undeclared offshore accounts.
Custodian: A financial institution that holds and safeguards a client's securities and cash. Custodians provide settlement services, collect dividends and interest, and produce statements. Under MiFID II, client assets must be segregated from the custodian's own assets. For international investors, using a regulated custodian with strong credit quality is essential.

D

DB Pension (Defined Benefit): A workplace pension where retirement income is guaranteed based on a formula — typically a fraction of final or average salary multiplied by years of service. DB pensions are funded by the employer and carry no investment risk for the member. They are increasingly rare in the private sector but remain common in public sector employment. Transferring out of a DB pension is irreversible and requires regulated advice for transfer values above £30,000.
DC Pension (Defined Contribution): A pension where contributions from the employer and/or employee are invested in a fund, and the final pot size depends on contributions made and investment returns. The member bears the investment risk. On retirement, the pot can be used to purchase an annuity, taken as drawdown, or accessed as lump sums. SIPPs are a form of DC pension.
Discretionary Trust: A trust in which the trustees have discretion over how and when to distribute income and capital among a defined class of beneficiaries. Unlike a bare trust, no beneficiary has a fixed entitlement. Discretionary trusts are widely used in estate planning because they offer flexibility and, if set up correctly, can keep assets outside the settlor's estate for IHT purposes. They are subject to ten-yearly and exit charges under UK trust taxation rules.
Domicile (Legal): A legal concept denoting the jurisdiction in which a person has their permanent home and to which they intend to return. Domicile is distinct from residence and nationality. UK domicile status has historically determined liability to UK IHT on worldwide assets, although the April 2025 reforms introduced the "long-term resident" concept as a parallel test. Changing domicile requires a genuine and permanent intention to settle elsewhere.
Double Taxation Treaty (DTT): A bilateral agreement between two countries that determines how income and gains are taxed when a taxpayer has a connection to both countries. DTTs typically allocate taxing rights over different income types (employment, dividends, pensions, property) and provide credits or exemptions to prevent the same income being taxed twice. The UK has DTTs with over 130 countries. Always check the specific treaty — provisions vary significantly.
Drawdown (Pension): A method of taking retirement income from a defined contribution pension pot, whereby the fund remains invested and the retiree withdraws income as needed. Drawdown preserves flexibility and allows the pot to grow, but exposes the retiree to sequence-of-returns risk. It is the most common approach used by HNW individuals who have diverse income sources and do not need to annuitise their pension.

E

EIS (Enterprise Investment Scheme): A UK government scheme offering significant tax reliefs to investors who subscribe for new shares in qualifying smaller UK companies. Income tax relief of 30% is available (up to £1 million invested per year, or £2 million if the company is "knowledge-intensive"). EIS shares also attract CGT deferral and, after two years, IHT relief via BPR (50% relief on unquoted/AIM holdings from 6 April 2026). EIS investments are high-risk and illiquid.
ERISA (US — Employee Retirement Income Security Act): A US federal law governing private-sector pension and employee benefit plans. ERISA is relevant to internationally mobile individuals who have worked in the United States, as US pension assets may be subject to its rules. Non-US pension schemes receiving transfers from ERISA plans face compliance complexities. US citizens living abroad must navigate both ERISA and the local pension rules of their country of residence.
Estate Planning: The process of arranging the management and eventual distribution of an individual's assets during their lifetime and at death, typically to minimise tax, avoid disputes and ensure assets pass to intended beneficiaries efficiently. International estate planning is complex: assets, beneficiaries and family members in multiple jurisdictions may be subject to different succession laws, forced heirship rules and tax regimes.
EURIBOR (Euro Interbank Offered Rate): The benchmark interest rate at which euro-area banks lend to one another in the interbank market, published daily for various maturities (1 week, 1, 3, 6 and 12 months). EURIBOR is widely used as a reference rate for euro-denominated floating-rate mortgages and loans across the EU. Expats and property investors in eurozone countries should understand their exposure to EURIBOR movements.

F

FATCA (Foreign Account Tax Compliance Act): A US law requiring foreign financial institutions (FFIs) to identify and report accounts held by US persons to the IRS, or face a 30% withholding tax on US-source payments. FATCA intergovernmental agreements (IGAs) mean that most countries' banks now automatically share US account holder data with the US. It affects US citizens and green card holders worldwide — even those who have lived outside the US for decades.
FCA (Financial Conduct Authority): The UK's financial services regulator, responsible for authorising and supervising financial firms and protecting consumers. FCA authorisation is required for investment advice, fund management and insurance distribution in the UK. Investors should always verify that their adviser holds FCA authorisation at register.fca.org.uk. Post-Brexit, EEA firms lost automatic passporting rights into the UK.
Fixed-Rate Bond: A debt instrument or deposit account paying a predetermined interest rate for a fixed term. Fixed-rate bonds provide certainty of income and capital (assuming issuer solvency) but do not benefit if rates rise. Offshore fixed-rate deposits can offer attractive rates in certain jurisdictions and currencies, though currency risk applies if the deposit is not in the investor's base currency.
Forex (Foreign Exchange): The global market for trading currencies, with a daily turnover exceeding $7 trillion. For international investors, forex exposure arises wherever assets are denominated in a currency other than the investor's base currency. Currency movements can enhance or erode returns significantly — a 10% currency depreciation on an overseas asset can wipe out an otherwise positive investment return.
Fund of Funds: An investment vehicle that allocates capital to a portfolio of underlying funds rather than directly to individual securities. Fund of funds structures are common in hedge fund and private equity investing, offering diversification and access to otherwise closed managers. The main drawback is a double layer of fees — charges at both the fund-of-funds level and the underlying fund level.

G

Golden Visa: A residency-by-investment programme granting residency rights (and often a pathway to citizenship) in exchange for a qualifying investment — typically in property, government bonds or business creation. Current programmes include those in Greece and the UAE; Portugal is now limited to non-property routes. Several schemes have closed or been struck down — Spain ended its Golden Visa in April 2025, the EU Court of Justice ruled against Malta's citizenship-by-investment scheme in April 2025, and Cyprus abolished its citizenship programme in 2020. Minimum investment thresholds and qualifying asset types vary by country and have been subject to frequent change. Due diligence on the programme and the investment is essential.
Gross Roll-Up (Offshore Bond): The ability of an offshore life assurance bond to accumulate investment returns free of tax within the policy. No income tax or capital gains tax arises on growth inside the bond during the investment period. This deferred taxation — gross roll-up — can produce significantly better outcomes over long periods compared with a taxed account, particularly for higher and additional rate taxpayers who plan to encash in a lower-tax period or jurisdiction.

H

Hedge Fund: An actively managed, lightly regulated investment fund typically available only to sophisticated or institutional investors. Hedge funds use a wide range of strategies — long/short equity, macro, arbitrage, event-driven — and may employ leverage and derivatives. The fee structure is typically "2 and 20": a 2% management fee and 20% performance fee. Returns are uncorrelated to traditional asset classes in theory, though this has not always held in practice.
High Water Mark (Fund): A provision in a fund's fee structure ensuring that performance fees are only charged on net new profits — i.e., the fund must recover any prior losses before the manager earns a performance fee again. High water marks protect investors from paying performance fees when a fund is merely recovering from previous drawdowns. They are standard practice in hedge funds and private equity.
HMRC (HM Revenue & Customs): The UK government department responsible for collecting taxes, including income tax, corporation tax, capital gains tax, inheritance tax, VAT and National Insurance contributions. HMRC also administers customs duties. For expats, HMRC is relevant for UK-source income, UK property disposals, reporting foreign income (the remittance basis having been abolished from 6 April 2025 and replaced by the four-year FIG regime), and completing annual self-assessment returns.
HNW (High Net Worth Individual): A person with investable assets (excluding primary residence and pension) exceeding a defined threshold — commonly £1 million or USD $1 million in financial services contexts. The FCA defines a "high net worth" client for regulatory purposes as having an annual income of at least £170,000 or net assets of at least £430,000 (thresholds in force from 31 January 2024). Ultra-high net worth (UHNW) typically refers to investable assets above $30 million.

I

IHT (Inheritance Tax): A UK tax charged on the estate of a deceased person at 40% on the value above the nil-rate band (£325,000 per person, with a further £175,000 residence nil-rate band where the family home passes to direct descendants). Transfers between spouses are exempt. Gifts made more than seven years before death are generally outside the estate. From April 2027, unspent pension pots will also be drawn into the IHT calculation.
ILAS (Investment-Linked Assurance Scheme): A form of unit-linked life assurance that wraps a portfolio of underlying funds within an insurance policy. ILAS products have been sold extensively in Hong Kong and Southeast Asia. They are structurally complex and have attracted regulatory criticism for opaque charges, lengthy lock-in periods and surrender penalties. Investors should scrutinise the total cost of ownership before committing to any ILAS product.
Income Protection Insurance: A long-term insurance policy that pays a replacement income if the policyholder is unable to work due to illness or injury. Payments typically begin after a deferred period (1–12 months) and continue until return to work, death or retirement. Expats should ensure their income protection policy remains valid in their country of residence — many UK policies exclude claims arising overseas or during extended periods abroad.
Index Fund: A fund that aims to replicate the performance of a specified market index (e.g., FTSE 100, S&P 500) by holding all or a representative sample of the index constituents. Index funds are passively managed and typically charge very low fees. They have consistently outperformed most actively managed funds over the long term on a net-of-fees basis, making them a core building block for many investment portfolios.
Intestacy: Dying without a valid will, so that the estate is distributed according to statutory intestacy rules rather than the deceased's wishes. Intestacy rules vary significantly between countries. International families are particularly vulnerable: the estate may be split between multiple jurisdictions' rules, assets may not pass to an unmarried partner, and different countries may have conflicting claims. A regularly updated will — ideally structured across relevant jurisdictions — is essential.

J

Joint Life Policy: A life assurance policy covering two lives (typically spouses or business partners). On the first death, the policy pays out and terminates. Joint life policies are often cheaper than two separate policies but provide no protection for the surviving partner after the claim. A common alternative for estate planning purposes is two single life policies written in trust for the benefit of the other.

K

KYC (Know Your Customer): A regulatory obligation requiring financial institutions to verify the identity and source of funds of their clients before providing services. KYC procedures typically involve passport verification, proof of address, and documentation of the origin of investable assets. Enhanced due diligence applies to politically exposed persons (PEPs) and individuals from higher-risk jurisdictions. Internationally mobile individuals are often subject to more extensive KYC requirements.

L

Leverage: The use of borrowed capital to increase the potential return on investment. Leverage amplifies both gains and losses. In property investment, leverage is used via mortgage financing; in fund investing, it may be achieved through derivatives or margin lending. Highly leveraged positions can be wiped out by relatively small adverse price movements, making leverage management a critical risk control.
LIBOR / SONIA: LIBOR (London Interbank Offered Rate) was the dominant global benchmark rate for variable-rate loans and derivatives for decades. It was discontinued in June 2023, replaced by risk-free rates: SONIA (Sterling Overnight Index Average) for sterling, SOFR for US dollars. The transition has affected floating-rate mortgages, corporate loans and many structured products.
Life Assurance vs Life Insurance (UK Distinction): In UK parlance, life assurance refers to a policy that will definitely pay out — either on death or at the end of a fixed term (endowment). Life insurance (or term assurance) only pays out if the insured dies within the policy term. Whole of life assurance is a permanent policy with no fixed end date. The distinction matters for tax purposes and for estate planning, as the certainty of payout affects the utility of the product.
Liquidity: The ease and speed with which an investment can be converted to cash at or near its fair market value. Publicly listed equities and government bonds are highly liquid; private equity, real estate and some hedge funds are illiquid. Investors should match liquidity requirements to their investment time horizon — holding illiquid assets when short-term cash needs are foreseeable creates forced-sale risk.
Loan Note: A debt instrument used in private transactions whereby a borrower promises to repay a lender a fixed amount on a specified date, typically with interest. Loan notes are commonly used in business acquisitions to defer the sale consideration and allow the seller to manage the timing of tax liabilities. For the buyer, loan notes provide purchase price flexibility; for the seller, they carry credit risk.
LTV (Loan-to-Value): The ratio of a loan to the value of the asset used as collateral, expressed as a percentage. A £200,000 mortgage on a £400,000 property represents an LTV of 50%. Lower LTV ratios typically attract better mortgage rates and indicate lower lender risk. Higher LTVs increase leverage and risk. International mortgage lenders may apply lower maximum LTV limits for non-resident buyers.

M

Margining: The process of depositing collateral with a broker or counterparty to cover potential losses on leveraged positions such as derivatives and CFDs. If a position moves against the investor, a "margin call" requires additional funds to be deposited. Failing to meet a margin call can result in the forced liquidation of the position. Margined products are high-risk and generally unsuitable for wealth preservation purposes.
Market-Linked Deposit: A deposit account where the return is linked to the performance of a market index, currency pair or basket of assets, but the deposited capital is protected. Market-linked deposits offer capital security (subject to bank solvency) with the potential for market-related upside — but typically cap participation in any market gains. They are suitable for cautious investors seeking inflation-beating returns without full equity risk.
MiFID II (Markets in Financial Instruments Directive): The EU's principal framework for regulating investment services and trading in financial instruments, implemented in 2018 and retained in UK law post-Brexit as the UK MiFID. MiFID II requires investment firms to provide clients with detailed cost disclosures (including all charges), to assess suitability before making personal recommendations, and to maintain best execution policies. It strengthened investor protections considerably over its predecessor.
Multi-Currency Account: A bank or investment account that holds multiple currencies simultaneously, allowing the holder to receive, hold and pay in different currencies without automatic conversion. Multi-currency accounts are particularly useful for international investors and frequent international travellers — they reduce conversion costs and provide a natural hedge against currency movements for individuals with income or expenses in multiple currencies.

N

NHR (Non-Habitual Resident — Portugal): A Portuguese tax regime that historically offered new tax residents a flat 20% rate on Portuguese-source income and exemptions on most foreign-source income for ten years. The NHR regime closed to new applications from 1 January 2024 and has been replaced by a narrower IFICI regime targeting specific professions and investors. Existing NHR status holders retain their benefits for the remainder of their ten-year period.
Non-Dom (Non-Domiciled): A person who is resident in the UK but whose permanent home (domicile) is considered to be in another country. Historically, non-doms could elect to pay UK tax only on income and gains remitted to the UK (remittance basis). The April 2025 reforms abolished the remittance basis and replaced it with a four-year Foreign Income and Gains (FIG) regime for new arrivals. Long-term UK residents (10+ years) are now taxed on worldwide income and gains regardless of domicile.
Nominee Account: An account in which securities are held in the name of a nominee (typically a broker or custodian) rather than in the beneficial owner's name. Nominee accounts simplify administration and settlement but mean the investor's name does not appear on the company's share register. The investor's rights are preserved as a beneficial owner and assets should be segregated from the nominee's own assets under FCA rules.
OECD BEPS (Base Erosion and Profit Shifting): An OECD/G20 initiative to reform international tax rules and close loopholes that allow multinational companies to shift profits to low-tax jurisdictions. BEPS has resulted in a global minimum corporate tax rate of 15% for large multinationals (Pillar Two), country-by-country reporting, and tightened rules on transfer pricing and hybrid mismatches. While primarily targeting corporates, BEPS measures affect investment structures used by HNW individuals.

O

Offshore Bond: A unit-linked life assurance policy issued by a life company based outside the UK, typically in the Isle of Man, Republic of Ireland, Channel Islands or Luxembourg. Growth within the bond is free from UK income tax and CGT (gross roll-up). A 5% annual tax-deferred withdrawal allowance applies. On surrender, top-slicing relief may reduce the income tax charge. Assignment to a lower-rate taxpayer or to a trust can be tax-efficient. Offshore bonds are a key planning tool for internationally mobile investors.
Offshore Trust: A trust established under the laws of a non-UK jurisdiction, with non-UK resident trustees. Offshore trusts can offer significant IHT planning benefits for non-UK domiciled individuals (excluded property trust status). Following April 2025 reforms, the excluded property treatment is preserved for genuine non-UK domiciliaries but has been restricted for long-term UK residents. Proper legal and tax advice is essential before establishing an offshore trust.
Open Architecture (Adviser Model): An advisory model in which the adviser has access to the full range of products and providers from across the market, rather than being limited to a panel or proprietary products. Open architecture means recommendations can be made purely on merit — cost, quality, suitability — without being influenced by product supplier relationships. It is a hallmark of truly independent financial advice under MiFID II and FCA rules.
Onshore vs Offshore Fund: Onshore funds are registered in the investor's country of residence and are subject to domestic tax rules. Offshore funds are registered outside the investor's country — commonly in Luxembourg, Ireland, Cayman Islands or Channel Islands. UK investors in 'reporting' offshore funds pay CGT on gains; investors in 'non-reporting' funds pay income tax on all gains. Most UCITS funds passported into the UK are technically offshore but qualify as reporting funds.

P

PAYE (Pay As You Earn): The UK system by which employers deduct income tax and National Insurance contributions from employees' wages at source and remit them directly to HMRC. Most employed individuals do not need to complete a self-assessment tax return if their only income is PAYE earnings. Expats returning to UK employment, or those with overseas employment income, will generally need to submit self-assessment returns.
Pension Lifetime Allowance (Abolished 2024): Previously, the Lifetime Allowance (LTA) was the maximum total value of pension savings an individual could accumulate without incurring a tax charge. From 6 April 2024, the LTA was abolished. In its place, a Lump Sum Allowance (£268,275) and Lump Sum and Death Benefit Allowance (£1,073,100) were introduced, limiting the amount that can be taken tax-free. Individuals who had previously applied for LTA protection should review whether their protection remains relevant under the new rules.
Permanent Establishment: A tax concept defining a fixed place of business through which an enterprise is taxed in a given jurisdiction — for example, an office, branch or factory. For internationally mobile HNW individuals who operate businesses, inadvertently creating a permanent establishment in a country can result in that country taxing a portion of the business's profits. Remote working arrangements have increased the complexity of permanent establishment analysis.
Portfolio Rebalancing: The periodic process of returning a portfolio to its target asset allocation by selling assets that have grown above target weights and buying those that have fallen below. Rebalancing maintains the risk profile of the portfolio and imposes a degree of contrarian discipline. For international investors, rebalancing across jurisdictions must account for transaction costs, withholding taxes and currency considerations.
Power of Attorney (International Context): A legal document authorising one person (the attorney) to act on behalf of another in financial, legal or property matters. Internationally mobile individuals should consider both UK and overseas Powers of Attorney — a UK LPA (Lasting Power of Attorney) may not be recognised abroad and vice versa. A separate PoA for each jurisdiction in which assets are held is often advisable.
QROPS (Qualifying Recognised Overseas Pension Scheme): See the Q section below.

Q

QROPS (Qualifying Recognised Overseas Pension Scheme): A pension scheme based outside the UK that has been recognised by HMRC as meeting minimum standards and that can receive a transfer from a UK-registered pension. QROPS are used by UK expats who wish to consolidate pension savings in their country of residence, access income without UK tax withholding, or benefit from different drawdown rules. An overseas transfer charge of 25% applies unless certain conditions are met (broadly, the member and the scheme are in the same country). The former exemption for transfers to QROPS in the EEA or Gibraltar was removed from 30 October 2024. Common QROPS jurisdictions include Malta, Gibraltar and New Zealand.
QNUPS (Qualifying Non-UK Pension Scheme): A foreign pension scheme that qualifies for an exemption from UK inheritance tax charges on pension assets. QNUPS can hold a wider range of assets than UK schemes and are sometimes used as part of offshore estate planning arrangements. HMRC has challenged arrangements where the primary purpose appears to be IHT avoidance rather than genuine retirement provision.

R

Remittance Basis: A now-abolished UK tax rule (from April 2025) under which non-UK domiciled UK residents were taxed only on overseas income and gains brought ("remitted") to the UK, rather than on the arising basis. The remittance basis has been replaced by the four-year Foreign Income and Gains (FIG) regime. Individuals who were claiming the remittance basis should take urgent advice on the new rules.
REIT (Real Estate Investment Trust): A company that owns income-producing real estate and distributes at least 90% of its taxable income to shareholders as dividends. REITs provide a liquid way to gain real estate exposure without direct property ownership. UK REITs are exempt from corporation tax on qualifying rental profits. For international investors, REIT dividends may be subject to withholding tax in the country of the REIT's domicile.
Risk-Adjusted Return: A measure of investment return that accounts for the level of risk taken to achieve it. The Sharpe ratio is the most common risk-adjusted return metric. A portfolio that achieves 8% per year with a Sharpe ratio of 1.2 is generally superior to one achieving 10% per year with a Sharpe ratio of 0.6, as the former generates more return per unit of risk. Risk-adjusted analysis is essential for comparing strategies with different volatility profiles.
RPI Escalation: Increases to pension or insurance payments linked to the Retail Price Index, historically higher than CPI. The UK government has sought to align RPI more closely with CPIH by 2030. Many older DB pensions and annuities provide RPI escalation — beneficiaries of such schemes should understand the value of this benefit, as it provides meaningful inflation protection over a long retirement.

S

SEIS (Seed Enterprise Investment Scheme): The smaller sibling of EIS, designed for investment in very early-stage UK companies. SEIS offers 50% income tax relief on investments up to £200,000 per year (from 2023/24), plus CGT exemption on gains after three years and CGT reinvestment relief. The companies must have assets under £350,000 and fewer than 25 employees. Very high risk — these are typically pre-revenue start-ups.
Sharpe Ratio: A measure of risk-adjusted return, calculated as (portfolio return − risk-free rate) ÷ portfolio standard deviation. A higher Sharpe ratio indicates better return per unit of risk. As a rough guide: a Sharpe ratio above 1 is considered good, above 2 is very good, and above 3 is exceptional. The ratio is most meaningful when comparing portfolios with similar investment universes.
SIPP (Self-Invested Personal Pension): A type of UK personal pension that gives the member control over where their pension is invested, including access to a wide range of assets such as shares, funds, bonds, commercial property and more. SIPPs are popular with HNW individuals and expats because of their flexibility. Contributions attract UK income tax relief (even for non-residents, subject to the £3,600 minimum threshold). On death before age 75, SIPP funds pass to nominated beneficiaries free of income tax.
Statutory Residence Test (SRT): The UK framework for determining whether an individual is resident in the UK for tax purposes. The SRT involves a series of tests considering days spent in the UK, ties to the UK (family, accommodation, work, 90-day tie) and prior residence history. The SRT replaced the old HMRC guidance in April 2013 and provides a more definitive framework, though it remains complex — particularly for individuals who split time between the UK and overseas.
Structured Note: A debt instrument whose return is linked to the performance of an underlying asset — an index, share, interest rate or currency. Structured notes offer customised payoff profiles: full or partial capital protection, enhanced participation in upside, or fixed coupons. They are issued by banks and carry the credit risk of the issuer. Liquidity in the secondary market may be limited, and early redemption values can be below the initial investment.
Succession Planning: The process of planning how wealth, business interests and other assets will pass to the next generation or intended beneficiaries. For international families, succession planning must account for the succession laws of every jurisdiction in which assets are held or family members are resident. Some countries (notably France and Spain) impose forced heirship rules that override a will. EU Succession Regulation 650/2012 allows EU residents to elect for the law of their nationality to govern their succession.

T

Tax Treaty: See Double Taxation Treaty (DTT) above. Tax treaties allocate taxing rights, set withholding tax rates and provide relief mechanisms. The OECD Model Tax Convention is the template used by most countries. Tax treaties do not eliminate tax obligations — they determine which country has the primary right to tax and what relief is available in the other.
Term Assurance: Life insurance that pays a lump sum if the insured dies within a specified term (e.g., 10, 20 or 25 years). If the insured survives the term, no benefit is paid and the policy expires. Term assurance is the most cost-effective form of life cover for most purposes (mortgage protection, income replacement for dependants). Expats should check that their policy remains valid while living abroad.
Top-Slicing Relief (Offshore Bond): A mechanism that reduces income tax on a chargeable event gain from an offshore bond by spreading the gain over the number of years the policy has been in force. The result is that only a fraction of the gain is added to income in the tax year of the chargeable event, which reduces or eliminates higher-rate tax where the taxpayer's income is otherwise below the higher-rate threshold. Careful timing of encashment can significantly reduce the tax liability.
Total Expense Ratio (TER) / Ongoing Charges Figure (OCF): The annual cost of owning a fund, expressed as a percentage of assets. The OCF (now the preferred term) includes the management fee plus other ongoing costs such as administration, custody and legal fees. Transaction costs and performance fees are excluded. A fund with an OCF of 0.20% costs £200 per year on a £100,000 investment. Charges compound over time — a 1% difference in annual charges can reduce a 20-year portfolio value by 15–20%.
Trustee: A person or corporate entity who holds and manages assets within a trust on behalf of the beneficiaries, in accordance with the trust deed. Trustees have fiduciary duties to act in the beneficiaries' best interests, invest prudently and administer the trust properly. For offshore trusts, choosing a regulated professional trustee in a reputable jurisdiction provides governance, accountability and legal standing.

U

UCITS (Undertakings for Collective Investment in Transferable Securities): An EU regulatory framework for retail investment funds that allows them to be sold across the EU (and many other countries) with a single authorisation. UCITS funds must meet strict diversification, liquidity and disclosure requirements. Most mainstream unit trusts, OEICs and ETFs available to retail investors are structured as UCITS. Post-Brexit, UK-domiciled funds lost UCITS passporting rights into the EU, though many moved to Ireland or Luxembourg.
Universal Life Insurance: A flexible permanent life assurance product combining a death benefit with a savings element that accumulates at a variable (market-linked) or minimum guaranteed interest rate. Common in the US and among internationally mobile clients served by US life companies. Premiums are flexible within limits, and the policy can be kept in force by drawing on the accumulated cash value. Sold extensively in Asian financial centres.
Unit-Linked: An investment or insurance product where the value is directly linked to the performance of underlying investment units (funds). Returns are not guaranteed — the investor bears the full investment risk. Unit-linked products include most offshore bonds, SIPPs, personal pensions and some life assurance policies. They contrast with with-profits products, where returns are smoothed.

V

Venture Capital: Equity investment in early-stage or growth-stage private companies, typically made by specialist VC funds. Venture capital is high risk and illiquid — most investments fail, but a small number may generate very high returns. In the UK, SEIS and EIS tax reliefs exist to encourage investment into smaller growth companies. Venture capital is suitable only for sophisticated investors with a long time horizon and high risk tolerance.
Volatility: A statistical measure of the dispersion of returns for an investment over time, typically expressed as annualised standard deviation. Higher volatility implies greater uncertainty of outcome — both higher potential gains and higher potential losses. In portfolio construction, volatility is a core risk metric used alongside correlation and expected return to optimise asset allocation for a given risk tolerance.

W

Warrant: A security that gives the holder the right — but not the obligation — to buy shares in a company at a specified price before a specified date. Warrants are similar to call options but are typically issued by the company itself rather than traded on an exchange. They are often attached to bonds or shares as a sweetener. Warrants have leverage: a small move in the underlying share price can result in a large percentage move in the warrant's value.
Whole of Life Insurance: A life assurance policy with no fixed end date — it pays out whenever the insured dies. Whole of life policies are widely used in IHT planning: a policy written in trust for beneficiaries provides funds to pay the IHT bill on death, without the proceeds forming part of the estate. Premiums are typically higher than term assurance because a payout is certain.
Withholding Tax: Tax deducted at source from payments of income (dividends, interest, royalties) made across borders. A company paying dividends to an overseas shareholder withholds a percentage for the local tax authority. The standard withholding tax rate is often 25–30%, reduced by tax treaty to 5–15%. Investors must understand the withholding tax rates applicable to their overseas income and claim treaty relief where available, either via reclaim or at source.

X

XBRL (eXtensible Business Reporting Language): A global standard for the electronic communication of financial data, used for submitting company accounts and regulatory filings digitally. XBRL is required for UK company accounts filed at Companies House (for certain companies) and for regulatory reporting. For international investors, understanding XBRL is less important than understanding the financial statements it encodes — but awareness is useful when interpreting standardised financial data.

Y

Yield: The income generated by an investment expressed as a percentage of its current price. Different types of yield are used in different contexts: dividend yield (dividends ÷ share price), running yield or current yield on bonds (annual coupon ÷ current price), and rental yield in property (annual rent ÷ property value). Yield-to-maturity (YTM) for bonds accounts for the price gain or loss if held to redemption. High yield usually implies higher risk.

Z

Zero-Coupon Bond: A bond that pays no periodic interest — instead, it is issued at a deep discount to its face value and redeems at par on maturity. The return is the difference between the purchase price and the redemption value. Zero-coupon bonds have higher duration (interest rate sensitivity) than coupon-paying bonds of the same maturity. They can be tax-efficient in certain structures where capital gains treatment is preferable to income tax.
