Estate Planning for High Net Worth Individuals

Estate planning for high net worth individuals works from the same allowances as any other estate, so the difference is one of scale: a larger estate is more likely to hold value above the tax-free bands, where the standard 40% inheritance tax rate can apply (gov.uk, as at July 2026, subject to change). The planning is about how the whole picture fits together.

This guide explains why the nil-rate bands often cover a smaller share of a wealthier estate, the mainstream and legitimate tools that tend to feature, such as spouse transfers, lifetime gifts and trusts, and the extra considerations that larger estates raise, including business and agricultural assets, residence and domicile, and later-life care. It sits within our wider estate planning guide and our Inheritance Tax Explained guide. Figures are current as at July 2026 and are subject to change.

What estate planning means for a larger estate

For a larger estate, planning generally means arranging assets and documents so that value passes to the intended people in an orderly, tax-aware way. Every person has a nil-rate band of £325,000, with up to a further £175,000 residence nil-rate band where a home passes to direct descendants (gov.uk, as at July 2026, subject to change). Above those bands, 40% can apply, so scale matters.

Why the tax-free bands run out sooner

The bands are fixed sums, not percentages, so they shield a smaller proportion of a larger estate. The ordinary nil-rate band is £325,000 per person and the residence nil-rate band is up to £175,000, giving up to £500,000 each and up to £1,000,000 for a couple where a qualifying home passes to descendants (gov.uk, as at July 2026, subject to change). Both are frozen to the end of the 2030-31 tax year (5 April 2031) (gov.uk, as at July 2026, subject to change).

Two further points bite harder on larger estates. First, the residence nil-rate band is tapered away where an estate exceeds £2,000,000, reducing by £1 for every £2 above that threshold (gov.uk, additional threshold, as at July 2026, subject to change). Second, the frozen bands mean that as asset values rise, a larger share of value drifts above them, depending on circumstances.

Mainstream planning tools compared

Larger estates tend to combine several legitimate tools rather than rely on one. Each has a different purpose, timescale and set of trade-offs, and none of them guarantees a particular tax result. The table sets out the mainstream options at a glance, and the sections that follow add detail. It can be worth discussing which combination fits with a qualified professional.

Lifetime gifts and the seven-year rule

Gifting is a common feature of larger-estate planning. Each person can give away up to £3,000 in total each tax year under the annual exemption, and can carry any unused annual exemption forward for one year only (gov.uk, rules on giving gifts, as at July 2026, subject to change). Smaller gifts of up to £250 per person each tax year can also be given to as many people as you like (gov.uk, as at July 2026, subject to change).

Larger outright gifts work differently. A gift generally falls outside the estate if the giver survives seven years, with no tax due after that point; gifts in the three years before death are charged at 40%, and taper relief can reduce the tax on gifts made between three and seven years before death (gov.uk, as at July 2026, subject to change). Keeping a benefit from a gift, such as continuing to live in a house given away, can make it a gift with reservation that stays in the estate (gov.uk, as at July 2026, subject to change).

Trusts in larger-estate planning

Trusts let someone set aside assets to be managed for others, which can help control when and how beneficiaries receive value, for example for young or vulnerable relatives. They are not a way to make tax disappear. Many trusts have their own inheritance tax charges: transfers into a relevant property trust above the available nil-rate band can attract a 20% lifetime charge if the trustees pay, and further charges of up to 6% can apply at ten-year anniversaries and when assets leave the trust (gov.uk, trusts and inheritance tax, as at July 2026, subject to change).

Trusts also bring administration, including possible registration on the Trust Registration Service, and their own income and capital gains tax treatment. Because the rules are involved, HMRC itself notes trusts are not always needed and suggests taking advice. Our note on reducing inheritance tax covers where trusts sit in the wider plan.

Business, company and agricultural assets

Where an estate includes a trading business, company shares or farmland, Business Relief and Agricultural Relief can reduce the value on which inheritance tax is charged, at either 100% or 50% depending on the asset (gov.uk, what qualifies for Business Relief, as at July 2026, subject to change). From 6 April 2026 these reliefs are being reformed, so that full 100% relief applies only up to a capped combined allowance, with 50% relief on qualifying value above the cap (gov.uk, reforms to APR and BPR, as at July 2026, subject to change).

These reliefs have detailed conditions, and the reform figures have been subject to further announcement, so the exact allowance can change. Investments and shares held for relief are regulated products in some cases, and this is general, educational information rather than a recommendation. Anyone with business or farm assets often reviews the position with a qualified professional, such as a STEP practitioner or an accountant, and, for any regulated investment, an FCA-authorised adviser.

Residence, domicile and cross-border assets

Where someone lives, and their long-term connection to the UK, can affect how their worldwide estate is treated for inheritance tax, and the rules in this area have been changing. Larger estates more often hold assets in more than one country, which can bring foreign taxes and succession laws into play alongside the UK position. This is a specialist area, and the interaction of jurisdictions generally calls for advice from a suitably qualified professional (gov.uk, as at July 2026, subject to change).

Later-life care and larger estates

Care fees planning tends to feature in later-life conversations, but it works differently from tax planning. If someone needs care, a local authority carries out a financial assessment, and where a person deliberately gives away or reduces assets to avoid paying care fees, the authority can treat those assets as still held under deprivation of assets rules and can seek to recover value (gov.uk, apply for a needs assessment, as at July 2026, subject to change). So gifts and trusts are not a route to deliberately avoid care fees.

For larger estates, the practical focus is usually on limiting and mitigating the impact of care fees within the rules, understanding how any means test works, and keeping documents such as a lasting power of attorney in place. Because the deprivation rules can be applied where intent is inferred, many people take advice from a suitably qualified professional before making significant gifts in later life.

Larger estates in Scotland and Northern Ireland

Inheritance tax is a UK-wide tax, so the £325,000 nil-rate band, the up to £175,000 residence nil-rate band, the 40% rate and the £2,000,000 taper threshold apply the same way across England, Wales, Scotland and Northern Ireland (gov.uk, as at July 2026, subject to change). The surrounding law differs. Scotland has its own succession rules, including legal rights that can give a spouse and children a fixed share of the estate, and uses confirmation rather than a grant of probate. Where assets or family sit across UK nations, it can be worth taking advice in each.
