When Did Inheritance Tax Start in the UK?

Understanding the history of inheritance tax in the UK is essential for anyone thinking about estate planning today. The tax that currently catches hundreds of thousands of families each year didn’t appear overnight — it evolved over more than three centuries of British taxation policy.

The roots of inheritance tax in the UK date back to 1694, when probate duty was first introduced to help fund the war against France. Over the centuries, various death duties have been introduced, reformed, merged, and replaced — eventually producing the inheritance tax system we have today. Knowing this history helps explain why the current rules work the way they do, and why proactive planning is more important now than ever.

Key Takeaways

• Death duties in the UK date back to 1694 — over 330 years of taxing wealth transfers on death.
• The modern inheritance tax was introduced in 1986, replacing Capital Transfer Tax.
• Rates have fluctuated dramatically — from as high as 85% on the largest estates to the current 40%.
• The nil rate band of £325,000 has been frozen since 2009 and will remain frozen until at least April 2031 — dragging more ordinary homeowners into the IHT net every year.
• Understanding the evolution of inheritance tax reveals why proactive estate planning — including the use of lifetime trusts — has never been more important.

Overview of Inheritance Tax in the UK

Inheritance tax (IHT) is a tax charged on the value of a person’s estate when they die. It applies to everything they owned — property, savings, investments, and personal possessions — as well as certain gifts made in the years before death. Introduced in its current form in 1986 under the Finance Act 1986, IHT replaced Capital Transfer Tax and has since become one of the most significant considerations in estate planning for families across England and Wales.

Below, we break down the key elements of how IHT works, its purpose, and why it matters for ordinary homeowners — not just the wealthy.

Definition and Purpose of Inheritance Tax

Inheritance tax is charged at 40% on the value of a deceased person’s estate that exceeds the nil rate band (currently £325,000 per person). The stated purpose is twofold: to generate revenue for the Treasury, and to act as a mechanism for wealth redistribution. In the 2023-24 tax year, HMRC collected over £7 billion in IHT — a figure that has been steadily rising as frozen thresholds pull more estates above the taxable limit.

The tax applies to various assets, including:

• Property (including the family home)
• Cash and savings
• Investments and pensions (inherited pension benefits will become liable for IHT from April 2027)
• Personal possessions of value
• Gifts made within seven years of death (potentially exempt transfers)

Key Features of Inheritance Tax

Some key features of inheritance tax include:

• Nil Rate Band (NRB): Each individual has a £325,000 tax-free allowance. This has been frozen since 6 April 2009 and is confirmed frozen until at least April 2031 — meaning it has lost significant value in real terms due to inflation, while house prices have continued to rise.
• Residence Nil Rate Band (RNRB): An additional £175,000 per person, but only available when a qualifying residential property is passed to direct descendants — children, grandchildren, or step-children. It is not available for gifts to nephews, nieces, siblings, friends, or charities. The RNRB tapers away by £1 for every £2 that the estate value exceeds £2,000,000.
• Spouse/Civil Partner Exemption: Transfers between spouses or civil partners (both UK domiciled) are completely exempt from IHT, and any unused NRB and RNRB can be transferred to the surviving spouse.
• Charitable Exemption: Gifts to registered charities are exempt, and if at least 10% of the net estate is left to charity, the IHT rate is reduced from 40% to 36%.

Understanding these features is crucial for effective estate planning. A married couple can currently pass on up to £1,000,000 free of IHT (£650,000 combined NRB + £350,000 combined RNRB) — but only if their estate is structured correctly and the RNRB conditions are met.

Importance of Inheritance Tax in Government Revenue

Inheritance tax is a significant and growing source of revenue for the UK government. HMRC collected over £7 billion in IHT in 2023-24, and this figure is projected to continue rising. The reason is straightforward: the nil rate band has been stuck at £325,000 since 2009, while the average home in England is now worth around £290,000. This means that for many families, the family home alone uses up almost all of their tax-free allowance — before savings, pensions, or other assets are even counted.

This is precisely why inheritance tax is no longer just a concern for the wealthy. Ordinary homeowners — people who have simply bought and kept their home over 20 or 30 years — are now being caught by a threshold that hasn’t kept pace with property prices. As Mike Pugh, founder of MP Estate Planning, often says: “Trusts are not just for the rich — they’re for the smart.” Understanding how IHT works, and planning ahead using tools like lifetime trusts, is vital for protecting the wealth your family has built.

Historical Context of Inheritance Tax

Inheritance tax, as we know it today, has its roots in various forms of death duties introduced over more than three centuries. Understanding this historical context is essential for grasping why the current system works the way it does — and why it catches so many families off guard.

Origins of Taxation in the UK

The earliest form of death duty in the UK was probate duty, introduced in 1694 during the reign of William III and Mary II. It was a relatively modest charge levied on the personal property of the deceased before probate could be granted. This marked the beginning of a long tradition of taxing wealth transfers at death.

Over the following two centuries, additional duties were layered on top. Legacy duty (1780) taxed bequests of personal property to beneficiaries, with rates varying depending on the closeness of the family relationship. Succession duty (1853) extended taxation to real property (land and buildings) for the first time. By the late 1800s, the patchwork of overlapping death duties had become complex and inconsistent. For a more detailed historical overview, you can refer to the Wikipedia article on the history of inheritance taxes in the United Kingdom.

Introduction of Estate Duty and the Path to Modern IHT

A significant milestone came with Sir William Harcourt’s Finance Act 1894, which introduced estate duty. This consolidated the various death duties into a single charge on the total value of a deceased person’s estate — a much simpler and broader approach. The initial rates ranged from 1% to 8%, with the top rate applying to estates over £1 million (an enormous sum in 1894). Estate duty became colloquially known as “death duties” and remained the primary form of inheritance taxation for over 80 years.

The evolution from estate duty to the modern inheritance tax reflects shifting attitudes towards wealth, fairness, and government revenue. The key milestones are summarised below:

The table above highlights the most significant turning points in the history of UK death duties, demonstrating a gradual shift from narrow, fragmented charges towards a single broad-based tax on wealth transfers.

Timeline of Inheritance Tax Development

The inheritance tax system we have in 2025 is the product of over three centuries of legislative change. Each reform was driven by the economic pressures and political priorities of its era — from funding wars in the 1690s to funding the welfare state in the post-war period.

Early Taxation Trends in the UK

The concept of taxing inherited wealth gained real momentum in the Victorian era. Before the consolidation of 1894, there were multiple overlapping charges: probate duty on personal estate, legacy duty on bequests, and succession duty on real property. Each had different rates and different rules — creating a confusing system that was ripe for reform. The Finance Act 1894 was a watershed moment, replacing this patchwork with a single estate duty that applied to all property passing on death.

During both World Wars, estate duty rates were increased dramatically to help fund the war effort. By the mid-20th century, the top rate of estate duty had climbed to 85% — applied to the very largest estates. This made estate duty one of the most punitive taxes in British history and drove significant avoidance activity, including the gifting of country estates to the National Trust.

Major Legislative Changes Over the Years

Three pieces of legislation define the modern history of death duties:

• Finance Act 1894: Introduced estate duty, consolidating earlier death duties into a single charge. Rates started at 1-8% and climbed steeply in later decades.
• Finance Act 1975: Replaced estate duty with Capital Transfer Tax (CTT). For the first time, lifetime gifts were also taxed — not just transfers on death. This was a significant expansion of the tax base.
• Finance Act 1986: Replaced CTT with inheritance tax (IHT). Crucially, this reintroduced the concept of potentially exempt transfers (PETs) — gifts to individuals that fall out of the estate entirely if the donor survives seven years. This made lifetime giving a central part of IHT planning.

Significant Milestones in Inheritance Tax History

Beyond the three major Acts, several other milestones have shaped the IHT landscape:

By examining this timeline, a clear pattern emerges: the thresholds and reliefs have consistently failed to keep pace with rising asset values, particularly property. The nil rate band has been frozen at £325,000 since 2009, while average house prices have risen by over 60% in the same period. This is why more ordinary families are being caught by IHT every year — and why early planning is essential.

How the Inheritance Tax Rate Has Changed

Understanding how IHT rates have changed over time gives valuable context for today’s estate planning decisions. The current 40% rate, while often described as punitive, is actually modest compared to historical peaks.

Overview of Changes in Tax Rates

The current standard inheritance tax rate is 40% on the taxable estate above the nil rate band. A reduced rate of 36% applies where at least 10% of the net estate is left to registered charities. For a broader historical perspective, the history of inheritance tax shows how rates have fluctuated with the political and economic climate.

Key rate changes through history include:

• 1894: Estate duty introduced at 1-8%
• 1914-1919: Rates increased significantly to fund the First World War
• 1940s-1960s: Top rates climbed to 80% and eventually 85% on estates over £2 million — the highest rates in UK history
• 1975: Capital Transfer Tax introduced with rates up to 75%
• 1986: Inheritance tax introduced at a flat rate of 40% above the threshold — where it has remained ever since
• 2012: Reduced rate of 36% introduced for estates leaving 10%+ to charity

Comparison of Historical and Current Rates

Comparing historical rates to today reveals an interesting picture. While the headline rate of 40% is far lower than the post-war peaks of 75-85%, the practical impact on families has arguably increased. Here’s why:

In the 1960s and 1970s, when rates were 75-85%, these top bands applied to only the very wealthiest estates — the aristocracy and major landowners. The ordinary homeowner was rarely affected. Today’s 40% rate applies to a much broader swathe of the population because the nil rate band (£325,000) has been frozen since 2009 while property values have surged. A couple owning a home worth £500,000 with modest savings and pensions can easily exceed the combined threshold — something that would have been inconceivable when estate duty was first introduced.

The reality is that the 40% rate, combined with frozen thresholds, means inheritance tax is quietly becoming a tax on ordinary homeowners rather than a tax solely on the wealthy. This is the single most important reason to plan ahead — using tools like lifetime trusts, gift planning, and proper use of reliefs and exemptions.

Exemptions and Allowances

While the headline IHT rate of 40% sounds alarming, the tax system provides a number of exemptions and allowances that can significantly reduce or even eliminate the bill — but only if you know about them and plan to use them.

Personal Allowance for Inheritance Tax

The UK inheritance tax system provides two main threshold allowances:

The nil rate band (NRB) of £325,000 per person means the first £325,000 of an estate passes tax-free. For married couples and civil partners, any unused NRB transfers to the surviving spouse — giving a combined maximum of £650,000.

The residence nil rate band (RNRB) of £175,000 per person applies when a qualifying residential property passes to direct descendants (children, grandchildren, or step-children). Again, it transfers between spouses — giving a combined maximum of £350,000. However, the RNRB has strict conditions: it is not available for gifts to siblings, nephews, nieces, friends, or charities, and it tapers away for estates valued above £2,000,000.

Together, a married couple can potentially pass on up to £1,000,000 free of IHT — but only with correct planning and only if the RNRB conditions are satisfied.

Key Exemptions Under Current Law

Beyond the nil rate bands, several important exemptions can be used as part of a comprehensive inheritance tax planning strategy:

• Spouse/civil partner exemption: Transfers between spouses or civil partners (both UK domiciled) are completely exempt from IHT — no limit.
• Charitable gifts: Gifts to registered charities are exempt. If 10%+ of the net estate goes to charity, the IHT rate on the rest drops from 40% to 36%.
• Annual gift exemption: Each person can give away £3,000 per tax year free of IHT, with one year’s unused allowance carried forward.
• Small gifts: Gifts of up to £250 per recipient per tax year are exempt (cannot be combined with the £3,000 annual exemption for the same person).
• Wedding/civil partnership gifts: £5,000 from a parent, £2,500 from a grandparent, £1,000 from anyone else.
• Normal expenditure out of income: Regular gifts made from surplus income (not capital) are exempt — but must be properly documented.
• Potentially exempt transfers (PETs): Gifts to individuals that fall completely outside the estate if the donor survives seven years. If the donor dies within seven years, taper relief may reduce the tax payable — but only where the cumulative value of gifts exceeds the nil rate band.
• Business Property Relief (BPR) and Agricultural Property Relief (APR): Currently 100% relief on qualifying business and agricultural assets, though from April 2026, BPR/APR will be capped at 100% for the first £1 million of combined qualifying property, with 50% relief on the excess.

By leveraging these exemptions and allowances — ideally with professional guidance — families can significantly reduce the IHT burden on their estates. The key is planning early: most of these reliefs require time to take effect, and none of them help if you leave it too late.

The Role of Inheritance Tax in Estate Planning

Understanding IHT isn’t just an academic exercise — it directly determines how much of your estate actually reaches your family. With frozen thresholds and rising property values, the gap between what families think they’ll inherit and what they actually receive after tax can be enormous.

Planning for Inheritance Tax

Effective estate planning starts with understanding your exposure. For many families, the family home is the single largest asset — and with the average home in England now worth around £290,000, it alone can use up most of the nil rate band. Add savings, investments, personal possessions, and (from April 2027) inherited pension death benefits, and it’s easy to see how estates of £500,000 or more face a significant IHT bill.

Reviewing your estate regularly is essential. Life events — marriage, divorce, the birth of grandchildren, property purchases, receiving an inheritance — all change your IHT position. What worked five years ago may no longer be sufficient.

Strategies to Minimise Inheritance Tax Liability

There are several legitimate, well-established strategies for reducing IHT liability. These are not loopholes — they are reliefs and structures that Parliament has deliberately put in place:

• Making gifts during your lifetime: Using annual exemptions (£3,000 per year) and making potentially exempt transfers to individuals, which fall outside the estate after seven years.
• Placing assets into lifetime trusts: A properly structured irrevocable lifetime trust — such as a Family Home Protection Trust — can protect assets from care fees, sideways disinheritance, and (depending on the trust type) IHT. England invented trust law over 800 years ago, and trusts remain one of the most powerful planning tools available. It’s worth noting that trusts are tax-efficient planning tools — not tax avoidance schemes — and they must be set up correctly by a specialist to achieve the intended benefits.
• Making use of all available allowances: Ensuring both spouses’ NRBs and RNRBs are fully utilised — this alone can shelter up to £1,000,000 for a married couple.
• Charitable giving: Leaving 10%+ of the net estate to charity reduces the IHT rate from 40% to 36%.
• Life insurance written into trust: Taking out a life insurance policy written into a trust (typically free to set up) means the payout goes directly to beneficiaries outside the estate — avoiding the 40% IHT charge entirely. This is one of the simplest and most cost-effective forms of IHT planning.
• Business Property Relief: Investing in qualifying business assets can currently attract 100% IHT relief, though the rules are tightening from April 2026 with relief capped at 100% for the first £1 million and 50% thereafter.

The most important principle is to plan early. As Mike Pugh says: “Plan, don’t panic.” Most IHT planning strategies require years to take full effect. Waiting until a health scare or a care need arises is almost always too late.

We strongly recommend seeking advice from a specialist in estate planning and trust law — not a generalist. As the saying goes: the law, like medicine, is broad — you wouldn’t want your GP doing surgery. IHT planning is a specialist area, and getting it wrong can be costly.

Public Perception of Inheritance Tax

Inheritance tax is one of the most unpopular taxes in the UK — consistently polling as the tax people consider most unfair. Yet it raises billions of pounds each year and shows no sign of being abolished. Understanding public attitudes helps explain the political dynamics that shape IHT policy.

Recent Polls and Surveys on Public Opinion

Polls consistently show strong public opposition to IHT. Key findings from various surveys include:

• A majority of respondents regularly describe IHT as “unfair” — with many citing the argument that assets have already been taxed through income tax, capital gains tax, and stamp duty during the owner’s lifetime.
• There is widespread support for raising the nil rate band to reflect current property values.
• Many people significantly underestimate how likely they are to be caught by IHT — particularly homeowners in London and the South East, where average property prices far exceed the £325,000 threshold.
• Despite its unpopularity, most polls show the public does not prioritise abolishing IHT when asked to rank tax reforms — other taxes (council tax, income tax) tend to take precedence.

These findings highlight a paradox: IHT is deeply disliked but politically survivable — which is exactly why families cannot rely on future governments to fix the problem for them. Planning now is the only reliable approach.

Arguments For and Against Inheritance Tax

The debate around inheritance tax is long-standing, with reasonable arguments on both sides:

1. For Inheritance Tax: It helps reduce the concentration of inherited wealth, contributing to greater social mobility and funding public services like the NHS, education, and infrastructure.
2. Against Inheritance Tax: It is widely perceived as double taxation — the assets have already been subject to income tax, national insurance, VAT, and stamp duty during the deceased’s lifetime. Taxing them again at 40% on death feels punitive to many families.
3. For Inheritance Tax: The revenue raised (over £7 billion in 2023-24) is substantial and funds services that benefit everyone.
4. Against Inheritance Tax: It can force families to sell the family home or other assets to pay the tax bill — particularly where wealth is tied up in property rather than liquid assets. This disproportionately affects asset-rich but cash-poor families.

Regardless of where you stand on the debate, the practical reality is the same: IHT exists, it is not going away, and the frozen thresholds mean more families are affected every year. The question isn’t whether IHT is fair — it’s whether you’ve taken steps to protect your family from it.

International Comparisons of Inheritance Tax

The UK’s approach to taxing inherited wealth is far from universal. Looking at how other countries handle this issue provides useful context — and sometimes raises uncomfortable questions about whether the UK system strikes the right balance.

Comparison with Inheritance Taxes in Other Countries

Inheritance and estate tax regimes vary enormously across the world:

• Australia, Sweden, and Canada: Have no inheritance tax at all. Australia abolished it in 1979, Sweden in 2004. This doesn’t mean inherited wealth goes untaxed — capital gains may be charged at other points — but there is no specific charge on death.
• France: Inheritance tax rates range from 5% to 45% depending on the relationship between the deceased and the beneficiary. Close family members benefit from significant exemptions — for example, each child receives a €100,000 allowance from each parent.
• Germany: Tax rates range from 7% to 50%, but generous exemptions apply for spouses (€500,000) and children (€400,000 per child from each parent).
• United States: The federal estate tax has a very high threshold (currently over $13 million per individual), meaning fewer than 0.1% of estates are affected. State-level inheritance taxes vary.
• Japan: Has one of the highest inheritance tax rates in the world, with a top rate of 55%.

Lessons from Other Tax Systems

Several observations emerge from international comparisons:

1. Threshold levels matter enormously: The US threshold means virtually no ordinary families pay estate tax there. The UK’s £325,000 threshold, frozen for over 16 years, catches a far broader range of homeowners.
2. Relationship-based rates can be fairer: Countries like France and Germany apply lower rates and higher exemptions for closer family members — recognising that passing the family home to your children is different from a large bequest to a distant relative.
3. Abolition is not impossible: Several developed nations have abolished inheritance tax entirely without catastrophic consequences for public finances — though they typically have other revenue mechanisms in place.

These international examples highlight that the UK’s current system — with its frozen thresholds, flat 40% rate, and limited reliefs — is relatively inflexible compared to many comparable economies. Until that changes, proactive planning using the tools that English law provides (particularly lifetime trusts, which England invented over 800 years ago) remains the most effective way to protect your family’s wealth. As Mike Pugh often says: “Keeping families wealthy strengthens the country as a whole.”

Future of Inheritance Tax in the UK

As we look ahead, the landscape of inheritance tax is shifting — and not in a direction that favours families. Recent government announcements confirm the nil rate band will remain frozen until at least April 2031, and new measures are tightening the reliefs that families have traditionally relied on.

Emerging Trends and Reforms

Several significant changes are already confirmed or in progress:

• Frozen thresholds until 2031: The NRB (£325,000) and RNRB (£175,000) will remain at their current levels for at least another six years. With property prices and inflation continuing to rise, this means more estates will be caught by IHT every year — a phenomenon known as “fiscal drag.”
• Inherited pensions becoming liable for IHT from April 2027: Pension death benefits — previously outside the scope of IHT — will become part of the taxable estate. For many families, this could add tens or hundreds of thousands of pounds to their IHT bill.
• BPR and APR reforms from April 2026: Business Property Relief and Agricultural Property Relief will be capped at 100% for the first £1 million of combined qualifying assets, with only 50% relief on the excess. This will hit farming families and small business owners particularly hard.

These changes make one thing clear: the direction of travel is towards more people paying more IHT — not less.

Implications for Estate Planning

The practical implication is straightforward: the window for effective IHT planning is narrowing, not widening. Strategies that rely on reliefs which are being reduced (like BPR/APR) need to be reviewed. Families who have been relying on pension wealth sitting outside the estate need to reconsider their plans before April 2027.

Most importantly, those who haven’t yet put a plan in place should act sooner rather than later. Many of the most effective planning tools — lifetime trusts, gift strategies, the seven-year rule for potentially exempt transfers — require time to work. You cannot start the seven-year clock on your deathbed, and you cannot transfer assets into a trust once a foreseeable need for care has arisen.

When you compare the one-off cost of setting up a trust to the potential costs of a 40% IHT bill — or care fees that can run to £1,200-£1,500 per week — it becomes one of the most cost-effective forms of protection available. A trust setup costs from around £850 for straightforward arrangements, which is the equivalent of just one to two weeks of care home fees — a one-time investment versus costs that continue until either death or depletion of assets to the £14,250 local authority threshold.

The message from history is consistent: those who plan ahead protect their families. Those who wait until the rules change, or until a crisis hits, inevitably pay more. As Mike Pugh says: “Not losing the family money provides the greatest peace of mind above all else.”
