13.1 Taxation of Income & Capital Gains

13.1 Taxation of Income & Capital Gains

Taxation represents one of the most critical determinants of net investment performance in private wealth management. A sophisticated investment strategy delivering robust gross returns can be severely compromised if structured without regard to tax incidence, statutory allowances, and anti-avoidance legislation. Wealth managers must navigate the boundaries between lawful tax mitigation (organizing client affairs within the clear letter and spirit of the law to minimize tax liability) and unlawful tax evasion (the deliberate concealment, misrepresentation, or non-declaration of taxable income and gains).

Principles of Direct Taxation in Wealth Management

Direct taxation is levied directly on the income, profits, and capital gains of individuals and corporate entities. In wealth planning, direct taxation is categorized primarily into:

• Income Tax: Levied on recurring income streams generated by employment, pensions, trading profits, property rents, savings interest, and corporate dividends.
• Capital Taxes: Levied on changes in the capital value of assets upon their disposal (Capital Gains Tax) or upon gratuitous transfers of wealth during lifetime or on death (Inheritance Tax).

Modern tax regimes apply a schedular or sliced system of taxation, where different categories of income are stacked in a statutory order and subjected to varying allowances, bands, and tax rates.

The UK Income Tax Structure

Income tax is calculated on total taxable income arising in a given tax year (6 April to 5 April of the following calendar year), following a prescribed statutory hierarchy:

1. Non-savings income (employment earnings, pensions, trading profits, property rental income) forms the base slice;
2. Savings income (bank and building society interest, fixed-income coupons) forms the middle slice; and
3. Dividend income (company dividends, collective investment scheme equity distributions) forms the top slice.

The Personal Allowance and the Tapering Trap

Every individual resident in the UK is entitled to a standard statutory Personal Allowance (£12,570), representing a 0% tax bracket on initial income. However, to introduce progressive burden-sharing among high earners, a statutory tapering rule applies under Section 35 of the Income Tax Act 2007:

• For individuals whose adjusted net income exceeds £100,000, the Personal Allowance is reduced by £1 for every £2 of income earned above £100,000.
• Consequently, when adjusted net income reaches £125,140 (£100,000 + [2 × £12,570]), the Personal Allowance is completely extinguished.

Effective Marginal Tax Rate between £100,000 and £125,140:
Income in this band is subject to the 40% Higher Rate of Income Tax.
In addition, for every £100 earned, £50 of Personal Allowance is lost.
Losing £50 of allowance subjects an additional £50 to tax at 40% = £20 additional tax.
Total tax on £100 = £40 (Higher Rate) + £20 (Lost Allowance) = £60.
Effective Marginal Rate = 60.0%

Wealth managers frequently employ proactive tax planning strategies—such as gross pension contributions or Gift Aid donations—to reduce adjusted net income back to £100,000, restoring the lost Personal Allowance and capturing effective 60% tax relief.

Income Tax Bands and Rates

Taxation of Savings Income

Savings income (interest from bank deposits, gilts, corporate bonds, and open-ended investment company fixed-income distributions) is subjected to specialized allowances before standard rates apply:

1. The Starting Rate for Savings

A specialized Starting Rate for Savings provides a 0% tax band on up to £5,000 of savings income. However, this starting rate is reduced pound-for-pound by non-savings income that exceeds the Personal Allowance. If a client has non-savings income of £17,570 or more (£12,570 Personal Allowance + £5,000), the Starting Rate for Savings is completely extinguished.

2. The Personal Savings Allowance (PSA)

Individuals are entitled to an annual Personal Savings Allowance, which taxes savings interest at a 0% rate based on their overall marginal income tax band:

• Basic Rate Taxpayers: Receive a £1,000 Personal Savings Allowance;
• Higher Rate Taxpayers: Receive a £500 Personal Savings Allowance;
• Additional Rate Taxpayers: Receive £0 (no Personal Savings Allowance).

Savings income exceeding the available PSA is taxed at the taxpayer's marginal rate for savings (20%, 40%, or 45%).

Taxation of Dividend Income

Dividends from direct corporate shareholdings and authorized equity investment funds are treated as the highest slice of an individual's total income.

1. The Dividend Allowance

Every taxpayer, regardless of their total earnings or marginal tax bracket, receives an annual Dividend Allowance (£500). Dividends falling within this allowance are subject to a 0% tax rate. However, the dividend income inside the allowance still counts towards the taxpayer's basic or higher rate tax bands when determining the tax rate applicable to subsequent income.

2. Dividend Tax Rates

Dividends in excess of the £500 Dividend Allowance are taxed at specialized dividend rates, reflecting the fact that corporate profits have already been subjected to Corporation Tax at the company level:

• Basic Rate Band: 8.75%
• Higher Rate Band: 33.75%
• Additional Rate Band: 39.35%

Capital Gains Tax (CGT) Framework

Capital Gains Tax (CGT) is charged under the Taxation of Chargeable Gains Act 1992 (TCGA 1992) on the capital gain realized upon the disposal of a chargeable asset by a chargeable person.

Concept of Disposal

A disposal for CGT purposes is not restricted to a conventional cash sale. It encompasses:

• Sale for cash or deferred consideration;
• Gift or transfer of beneficial ownership to another individual or trust (deemed to occur at open market value under Section 17 TCGA 1992, except between spouses);
• Exchange or barter of assets (e.g., swapping shares in Company A for physical commodities);
• Receipt of a capital sum derived from an asset (e.g., insurance compensation for damaged art);
• Loss or destruction of a capital asset.

Exempt Assets

Certain asset classes are statutorily exempt from Capital Gains Tax:

• Principal Private Residence (PPR): An individual's only or main domestic dwelling, protected by Private Residence Relief;
• UK Gilts and Qualifying Corporate Bonds (QCBs): Direct holdings in UK sovereign debt (gilts) and sterling-denominated corporate debt complying with QCB rules;
• Private Motor Vehicles: Passenger motor cars suitable for private use;
• National Savings & Investments (NS&I): Premium Bonds, Index-linked Savings Certificates;
• Foreign Currency: Held for personal expenditure abroad;
• Assets inside Tax Wrappers: Investments held within Individual Savings Accounts (ISAs) and registered pension schemes.

The Annual Exempt Amount (AEA) and CGT Rates

Every individual is entitled to an Annual Exempt Amount (AEA) of capital gains per tax year (£3,000). Net gains below this threshold are completely tax-free and cannot be carried forward if unused.

When net chargeable gains exceed the AEA, the applicable CGT rate depends on the taxpayer's total taxable income (including non-savings, savings, and dividend income) and the asset category:

Rate Alignment — a Recent Change: For disposals made on or after 30 October 2024, the main CGT rates on shares, funds and other non-residential assets were raised from 10%/20% to 18%/24%, matching the residential property rates that had applied since 2016. A candidate who memorised the old 10%/20% pair from a pre-2025 textbook will get every current rate question wrong. Business Asset Disposal Relief, taxed at 10% until 5 April 2025 and 14% for 2025/26, rose to 18% for disposals from 6 April 2026, ending the BADR rate advantage over the ordinary basic rate.

Note on Rate Calculation: CGT rates are still banded against income. If a basic rate taxpayer has £10,000 of unused basic rate band remaining after accounting for all taxable income, the first £10,000 of capital gains above the AEA is taxed at 18%, and any remaining gains are taxed at 24%. Because the two asset categories now share the same rate pair, the practical planning question has shifted from which asset to whose basic rate band — inter-spouse transfers before disposal remain the principal rate-management tool.

Allowable Expenditure and Net Gain Determination

The chargeable gain is calculated by deducting statutory allowable expenditure from the disposal consideration:

$\text{Chargeable Gain} = \text{Gross Disposal Proceeds} - (\text{Acquisition Cost} + \text{Incidental Acquisition Costs} + \text{Enhancement Expenditure} + \text{Incidental Disposal Costs})$

1. Acquisition Cost: Original purchase consideration, or market value at acquisition if acquired via gift or inheritance.
2. Incidental Costs of Acquisition: Legal conveyancing fees, surveying charges, stamp duty / Stamp Duty Land Tax (SDLT) / Stamp Duty Reserve Tax (SDRT), and broker commissions.
3. Enhancement Expenditure: Capital expenditure incurred entirely for the purpose of enhancing the asset's value, provided that enhancement is reflected in the state or nature of the asset at the time of disposal (e.g., building a physical extension to an office building). Routine maintenance, repairs, and decorating are revenue expenses and strictly prohibited from CGT deduction.
4. Incidental Costs of Disposal: Estate agent fees, advertising costs, legal fees, auctioneer commissions, and transfer stamp duties.

Capital Loss Offset and Carry-Forward Mechanics

Where an asset is disposed of for less than its allowable expenditure, an allowable capital loss arises:

• Current Year Losses: Allowable losses realized in the current tax year must be offset immediately against current year chargeable gains, even if this reduces net gains below the Annual Exempt Amount, wasting the allowance.
• Carried-Forward Losses: If current year losses exceed current year gains, the excess loss is carried forward indefinitely to set against future chargeable gains. Crucially, brought-forward losses need only be used to reduce net gains down to the Annual Exempt Amount in future years, preserving the taxpayer's annual exemption.

Portfolio Tax Engineering: Bed & ISA Transactions

A Bed and ISA transaction is an established wealth planning technique designed to transition taxable assets into a tax-sheltered ISA wrapper without injecting fresh external cash:

1. The investor instructs their broker to sell shares held within an unwrapped General Investment Account (GIA), deliberately triggering a CGT disposal.
2. If planned effectively, the realized gain falls within the investor's remaining £3,000 Annual Exempt Amount, incurring zero CGT liability.
3. The cash proceeds are immediately subscribed into the investor's Stocks and Shares ISA (subject to the £20,000 annual ISA allowance).
4. The ISA manager immediately repurchases the identical shares within the ISA wrapper.

Outcome: The investor maintains uninterrupted economic exposure to the underlying company, utilizes their otherwise perishable CGT allowance, rebases the asset's acquisition cost, and shelters all future capital gains and dividend yields from taxation forever.

Anti-Avoidance: The 30-Day Share Matching Rules

Historically, investors engaged in "bed and breakfasting"—selling shares on the afternoon of 5 April to crystallize a capital loss or utilize an expiring CGT exemption, and repurchasing the exact same shares on the morning of 6 April. To defeat this artificial practice, Section 104 to Section 106 of the TCGA 1992 mandate strict share identification matching rules.

When an investor disposes of shares of the same class in the same company, the disposed shares must be matched against acquisitions in the following statutory chronological order:

1. Same-Day Rule: Disposals are matched first against shares of the same class acquired by the same individual on the exact same calendar day.
2. The 30-Day "Bed and Breakfast" Rule: Disposals are matched next against acquisitions made within the 30 calendar days following the disposal (matched on a First-In, First-Out [FIFO] basis if multiple purchases occur within the 30-day window).
3. The Section 104 Pool (Average Cost Holding): Any remaining disposed shares that are not matched under the same-day or 30-day rules are matched against the investor's general Section 104 pooled holding. All shares of that class acquired prior to the disposal date form a single collective pool, with an aggregated allowable cost and a uniform weighted average acquisition cost per share.

Business Taxes, Transaction Taxes and Taxes on Sales

The syllabus separates the taxes applying to individuals (income, capital gains, estate, stamp duty, sales tax) from the main business taxes an adviser must recognise. A private client who owns a company is exposed to both layers, and the interaction determines how wealth is best extracted.

1. Business tax (corporate income tax)

A company is a separate taxable person and pays tax on its taxable profits before any distribution to owners.

• The UK main rate of corporation tax is 25% on profits above £250,000, with a 19% small profits rate below £50,000 and marginal relief tapering between the two thresholds. Rates vary widely internationally — Ireland 12.5% on trading profits, the US federal rate 21%, the UAE 9% above a de minimis — which is why holding-company location is a live planning question.
• The OECD Pillar Two global minimum tax imposes a 15% effective floor on large multinational groups, materially reducing the value of routing profits through low-tax jurisdictions.
• Double taxation of distributed profits is the structural feature that matters for wealth planning: profit is taxed at the corporate rate, then again in the shareholder's hands as a dividend. The owner-manager's extraction decision — salary (deductible for the company, subject to income tax and social security) versus dividend (not deductible, but taxed at lower dividend rates) versus pension contribution (deductible and outside the personal charge) — is a direct application of this arithmetic.

2. Transaction taxes

Levied on the act of transferring an asset, regardless of whether a profit arises:

Purchases of gilts, most corporate bonds, ETFs domiciled outside the UK, and units in open-ended funds are exempt from SDRT — a fact that quietly changes the after-cost case for holding an index through an ETF rather than a basket of shares.

3. Taxes on sales (indirect / consumption taxes)

Value Added Tax (VAT) in the UK and EU, and sales tax or goods and services tax elsewhere, are charged on consumption rather than on income or gains. They are regressive relative to income (a lower earner spends a larger share of income) and are collected by businesses on the state's behalf.

• The UK standard rate is 20%, with reduced (5%) and zero rates on defined categories.
• For a wealth manager the direct relevance is fee treatment: discretionary portfolio management services are generally subject to VAT, whereas the management of a regulated collective investment scheme is exempt. Two economically similar services can therefore carry a 20% cost difference, which must be disclosed to the client in the total cost of ownership.

The layered picture an examiner expects: profits are taxed once in the company (business tax), again on extraction (income or dividend tax), again on the transfer of assets (transaction tax), again on consumption of the proceeds (sales tax), and finally on death (estate tax). Effective wealth planning works on the sequence of those layers, not on any single one.
