High Net Worth Tax Planning: Protecting and Structuring Wealth

High net worth tax planning is an ongoing process that brings together income, investments, property, pensions, business interests, family wealth and international assets. For individuals with complex financial affairs, tax decisions should not be considered in isolation. A large dividend, investment disposal, pension contribution or lifetime gift may affect several taxes at the same time. These decisions all interact with the core Income Tax rules explained in our ultimate guide to personal tax in the UK. Coordinated planning can help preserve wealth, manage cash flow, use available reliefs and reduce the risk of unexpected HMRC liabilities.

Why Tax Planning for High Net Worth Individuals Matters

Tax planning for high net worth individuals is often more complex because income and gains may arise from employment, dividends, partnerships, rental property, investment portfolios, trusts, private companies and overseas assets. This creates legitimate planning opportunities, but it also increases the risk of missed reliefs, inconsistent reporting and duplicated tax. For example, receiving additional income may affect the Personal Allowance, pension contribution limits and the rate of tax applied to investment income. Effective high net worth tax advice should therefore consider the individual’s complete financial position, long-term objectives and need for liquidity.

Income Tax and Dividend Planning

The standard Personal Allowance for 2026/27 is £12,570. It is reduced by £1 for every £2 of adjusted net income above £100,000 and is normally lost completely when adjusted net income reaches £125,140. This creates a high effective rate of tax on income within the allowance taper. Individuals close to this range may benefit from reviewing their taxable income before the end of the tax year. Potential planning measures may include:

• Making qualifying pension contributions
• Using salary sacrifice where appropriate
• Making Gift Aid donations
• Reviewing the timing of bonuses and dividends
• Transferring suitable income-producing assets between spouses or civil partners
• Considering whether company profits should be retained or extracted

This kind of household-level planning is not unique to high earners, even couples with a significant income gap between them, such as one partner drawing a small salary from a family business, should check whether saving tax using the Marriage Allowance applies before assuming it’s only relevant to lower earners generally. Transfers between spouses and civil partners who live together are generally made on a no-gain, no-loss basis for Capital Gains Tax. The transfer must be genuine, and the beneficial ownership of the asset should support the resulting allocation of income. From 6 April 2026, the ordinary dividend tax rate is 10.75%, the upper rate is 35.75% and the additional rate remains 39.35%. Company owners should compare salary, dividends, employer pension contributions and retained profits rather than selecting a method based only on the lowest immediate tax charge. For additional-rate taxpayers based in the capital, our guide on tax efficiency in London for additional rate earners looks at some of these questions in more location-specific detail.

Capital Gains Tax Planning

The Capital Gains Tax annual exempt amount for individuals is £3,000 in 2026/27. Because the exemption is limited, the timing of investment and property disposals can have a significant effect on the tax payable. Capital Gains Tax planning may involve:

• Using the annual exempt amount each year
• Timing disposals across different tax years
• Transferring assets between spouses or civil partners before disposal
• Using available capital losses
• Reviewing eligibility for Business Asset Disposal Relief

From 6 April 2026, qualifying gains covered by Business Asset Disposal Relief are generally taxed at 18%. Detailed ownership, employment and trading conditions must be met before the relief can be claimed. Tax should not be the only factor when deciding whether to sell an investment. Liquidity, investment risk, diversification and long-term growth should also be considered.

Inheritance Tax and Estate Planning

Inheritance Tax is generally charged at 40% on the taxable value of an estate above the available thresholds after exemptions and reliefs have been applied. For 2026/27, the standard nil-rate band remains £325,000. A residence nil-rate band of up to £175,000 may also be available where a qualifying home passes to direct descendants. The residence nil-rate band begins to taper where the value of the estate exceeds £2 million. Common estate-planning measures include:

• Making lifetime gifts
• Using the annual gift exemption
• Making regular gifts from surplus income
• Reviewing life assurance written in trust
• Using trusts where control or succession planning is important
• Updating wills and lasting powers of attorney

Gifts made under the normal expenditure out of income exemption must generally form part of a regular pattern, be made from income and leave the donor with enough income to maintain their usual standard of living. Clear records should be kept for significant gifts, particularly where an Inheritance Tax exemption may later need to be supported.

International Tax Planning

International HNW tax planning changed significantly from 6 April 2025. The former remittance basis was replaced by the four-year foreign income and gains regime. Eligible individuals who become UK resident after at least 10 consecutive years of non-UK residence may claim relief on qualifying foreign income and gains during their first four years of UK residence. Individuals who do not qualify are generally taxed on worldwide income and gains as they arise, subject to foreign tax credits and relevant double-tax treaties. Inheritance Tax also moved towards a residence-based system from 6 April 2025. Broadly, a person who has been UK resident for at least 10 of the previous 20 tax years may fall within the scope of UK Inheritance Tax on overseas assets. Transitional rules and provisions applying after departure may affect the position. Internationally mobile individuals should review:

• UK statutory residence status
• Eligibility for the four-year foreign income and gains regime
• Overseas trusts and companies
• Foreign tax credits and treaty relief
• Inheritance Tax exposure on overseas assets
• Historic foreign income and gains

Planning based on the former domicile and remittance-basis rules may no longer produce the intended result.

Pension Planning for High Net Worth Individuals

Pensions remain an important part of wealth tax planning, but high earners must consider annual allowance restrictions before making substantial contributions. The standard pension annual allowance is generally £60,000 for 2026/27. It may be reduced where threshold income and adjusted income exceed the relevant limits. The minimum tapered annual allowance is £10,000. Unused annual allowance may sometimes be carried forward from the previous three tax years, provided the relevant conditions are met. Individuals who have flexibly accessed money purchase pension benefits may also be subject to the Money Purchase Annual Allowance, which can restrict future tax-relieved contributions. The pension Lifetime Allowance was abolished from 6 April 2024. For 2026/27, the standard lump sum allowance is £268,275 and the standard lump sum and death benefit allowance is £1,073,100. Individuals with valid pension protections may have higher limits. Before making a large pension contribution, it is important to check the available annual allowance, any carry-forward entitlement and whether tapering or the Money Purchase Annual Allowance applies.

Business, Property and Investment Structures

Business owners often have a wider range of planning options because wealth may be held personally, within a trading company, through a holding company or in a pension arrangement. Planning may cover salary and dividends, employer pension contributions, directors’ loan accounts, surplus company cash, succession arrangements and preparation for a future business sale. Reliefs connected with business disposals or succession often depend on ownership periods and the trading status of the company. Planning should therefore begin well before a proposed sale or restructuring. Family investment companies may provide a structured way to hold and transfer family wealth while allowing founders to retain a degree of control. However, they create Corporation Tax, dividend tax, governance, valuation and reporting obligations. Trusts can also support control, protection and succession, but they may create immediate Inheritance Tax charges, ten-year anniversary charges, exit charges and higher rates of Income Tax and Capital Gains Tax. Neither a trust nor a family investment company should be viewed as an automatic tax-saving solution. The legal, commercial and family objectives should be clear before the structure is established. Property planning should consider rental Income Tax, mortgage interest restrictions, Capital Gains Tax, Stamp Duty Land Tax, ownership structure and succession objectives. The most appropriate structure depends on financing, expected holding period, intended use and whether income needs to be withdrawn personally. ISAs can shelter qualifying investments from Income Tax and Capital Gains Tax. Although the annual subscription limit may be modest compared with a high-value portfolio, using the allowance consistently can create a substantial tax-free investment fund over time. For investors looking beyond ISAs, reviewing venture capital schemes and which is the best choice for their circumstances can offer further tax-advantaged investment opportunities, subject to the higher risk involved.

Charitable Giving

Gift Aid can increase the value received by a qualifying charity while allowing higher-rate and additional-rate taxpayers to claim further Income Tax relief. Qualifying donations can also extend the basic-rate band and reduce adjusted net income. This may help restore part of the Personal Allowance where income is above £100,000. Donations of qualifying shares, securities or land may provide both Income Tax and Capital Gains Tax relief, subject to the detailed conditions.

HMRC Compliance for High Net Worth Individuals

HMRC receives financial information from employers, banks, investment platforms, Companies House, overseas tax authorities and property records. High net worth taxpayers should ensure that tax returns are consistent with third-party data and that all investment income, foreign income, gains, trusts and property interests have been reviewed. Good records should include portfolio statements, tax certificates, transaction documents, foreign tax evidence, valuations and information supporting legal and beneficial ownership. Where the tax treatment of a transaction is uncertain, a clear disclosure can reduce the risk of HMRC viewing an omission as careless or deliberate.

Common High Net Worth Tax Planning Mistakes

• Waiting until the Self Assessment deadline to begin planning
• Ignoring the Personal Allowance taper
• Making pension contributions without checking annual allowance restrictions
• Using outdated domicile or remittance-basis assumptions
• Creating trusts or companies without a clear commercial or family purpose
• Failing to coordinate tax, legal and investment advisers
• Focusing on tax savings without considering liquidity or investment suitability

High Net Worth Tax Planning Case Study

Jonathan, a successful business owner with a diverse investment portfolio, visited our Fulham Broadway office after realising that his growing wealth was creating increasingly complex tax obligations. His income came from company dividends, rental properties, investment gains and pension contributions, and he wanted comprehensive high net worth tax planning to ensure his affairs were structured as tax-efficiently as possible while remaining fully compliant with HMRC.

We carried out a detailed review of Jonathan’s overall financial position rather than looking at each tax separately. Our advisers assessed his Income Tax exposure, dividend strategy, Capital Gains Tax planning, pension contributions, Gift Aid donations and property ownership structure to identify opportunities for legitimate tax efficiencies. We also reviewed his inheritance planning, considered whether transferring assets between spouses could improve overall tax outcomes and ensured his investment and business decisions aligned with his long-term succession objectives. Finally, we checked that his records and reporting processes would satisfy HMRC’s increasing compliance requirements.

Throughout the consultation, we emphasised that effective tax planning for high net worth individuals requires coordinated planning across multiple taxes rather than focusing solely on reducing one year’s tax bill.

By the end of the review, Jonathan had a structured long-term tax strategy designed to preserve wealth, improve cash flow and support future family and business objectives while remaining fully compliant with HMRC requirements.
