A practical overview of the strategies, structures, and reliefs available to UK families seeking to protect their wealth across generations.
Inheritance Tax (IHT) is often described as a voluntary tax — not because it doesn't apply, but because with proper planning, much of it can be legitimately reduced or eliminated. Yet HMRC collected over £7.5 billion in IHT receipts in 2023/24, a figure that continues to rise as frozen thresholds meet rising asset values.
This guide is written for UK-based business owners, professionals, and families who have accumulated meaningful wealth and want to understand the full range of tools available to them. It is not a substitute for personalised advice — every family's circumstances are unique — but it provides the foundation you need to have informed conversations with your advisers.
The thresholds and rates that determine your starting position
Every individual has a tax-free allowance of £325,000. This has been frozen since 2009 and is legislated to remain so until at least April 2028. Any estate value above this threshold is taxed at 40%.
An additional £175,000 allowance is available when a home (or its sale proceeds) passes to direct descendants — children, grandchildren, or their spouses. However, this allowance tapers for estates exceeding £2 million, reducing by £1 for every £2 above the threshold. For estates over £2.35 million, the RNRB is lost entirely.
Assets passing between spouses or civil partners are exempt from IHT. Additionally, any unused NRB and RNRB can be transferred to the surviving spouse, potentially doubling the combined allowances to £1 million. This is powerful but can create complacency — the tax is deferred, not eliminated.
| Allowance | Individual | Couple (Combined) |
|---|---|---|
| Nil-Rate Band | £325,000 | £650,000 |
| Residence Nil-Rate Band | £175,000 | £350,000 |
| Total Tax-Free | £500,000 | £1,000,000 |
The simplest and most widely used method of reducing your estate
Gifts made to individuals become fully exempt from IHT if you survive for 7 years. If you die within 7 years, the gift is brought back into your estate — but taper relief reduces the tax payable on a sliding scale.
| Years Survived | Tax Reduction |
|---|---|
| 0–3 years | 0% (full tax) |
| 3–4 years | 20% reduction |
| 4–5 years | 40% reduction |
| 5–6 years | 60% reduction |
| 6–7 years | 80% reduction |
| 7+ years | Fully exempt |
Section 21 IHTA 1984 — one of the most underused reliefs
Gifts made from surplus income — income you don't need for your normal living expenses — are immediately exempt from IHT with no 7-year waiting period. There is no cap on the amount, provided three conditions are met:
The key is meticulous record-keeping. HMRC will scrutinise these claims using form IHT403, so a clear, contemporaneous surplus income register is essential.
Potentially the most powerful relief for business owners
Qualifying business assets can receive 100% or 50% relief from IHT, effectively removing them from your taxable estate entirely.
| Asset Type | Relief |
|---|---|
| Unquoted trading company shares (including AIM) | 100% |
| Sole trader / partnership interest | 100% |
| Controlling holding in a quoted company | 50% |
| Land, buildings, or machinery used in the business | 50% |
Assets must have been held for at least 2 years. Investment companies (primarily holding investments rather than trading) do not qualify.
Removing assets from your estate while retaining control or protecting beneficiaries
Assets are held by trustees for the benefit of a class of beneficiaries. The settlor retains no beneficial interest, so the assets are outside the estate. Subject to a maximum 6% charge every 10 years (the periodic charge) and exit charges when capital is distributed.
A named beneficiary (the life tenant) receives the income or use of the trust assets during their lifetime, with the capital passing to remaindermen on their death. Useful for providing for a spouse while protecting capital for children from a previous marriage.
The beneficiary has an absolute right to the capital and income. Often used for gifts to minor children or grandchildren. The gift is treated as a PET, becoming exempt after 7 years.
You invest a lump sum, retain the right to fixed withdrawals (typically 5% per annum), and the remainder is treated as a gift. The "discount" — the difference between the investment and the retained rights — is an immediate reduction to your estate, with no 7-year wait.
A modern structure for multi-generational wealth transfer with retained control
A Family Investment Company is a private limited company where the founder holds shares carrying voting rights and control, while family members (often children or grandchildren) hold shares carrying economic value (growth shares or dividend shares).
From IHT shelter to taxable asset — and what to do about it
Until now, pension funds have been outside the scope of IHT. This made pensions a powerful estate planning tool — spend other assets, preserve the pension, pass it on tax-efficiently.
Funding the tax bill without reducing the estate
Life insurance doesn't reduce IHT — it provides the liquidity to pay it. However, it must be written in trust to be effective. If the policy is held personally, the payout is added to the estate and taxed at 40%.
The 36% rate and how philanthropy can reduce the tax burden
Gifts to registered charities are exempt from IHT. Additionally, if you leave 10% or more of your net estate to charity, the IHT rate on the remainder reduces from 40% to 36%.
The 10% test is applied to the "baseline amount" — the net estate after deducting liabilities, exemptions, the NRB, and the RNRB. For larger estates, the 4% rate reduction can sometimes mean the family receives more after tax than if no charitable gift had been made.
For families with farmland and agricultural interests
Agricultural land and property can qualify for 100% relief (if the owner has the right to vacant possession or the land is let on a post-1995 tenancy) or 50% relief (for older tenancies). The land must have been occupied for agricultural purposes for at least 2 years (if farmed by the owner) or 7 years (if let out).
Note: Recent Budget proposals may restrict APR for larger holdings. Professional advice is essential.
Why individual strategies fail without a coherent plan
Each of the strategies outlined above is well-established and HMRC-recognised. The challenge lies not in knowing what they are, but in understanding how they interact — and implementing them in the right sequence, with the right structures, at the right time.
Effective estate planning requires your financial planner, solicitor, accountant, and trustees to work from the same strategy — not in silos. This is the difference between a collection of tactics and a coherent plan.
This guide provides the framework. Your specific circumstances — business structure, family dynamics, asset types, domicile status, and timeline — will determine which combination of strategies is appropriate.
