Will Your Estate Pay Inheritance Tax? Understanding how the UK Inheritance Tax System Operates

Inheritance Tax is one of the most widely discussed UK taxes, and also one of the most misunderstood. This misconception also brews from people feeling like only the super wealthy have to bear the IHT burden and their kin are oftentimes blindsided by the IHT bill on their death estate (although it is no longer their burden to bear), affecting families who have built up property and savings over many years, also in situations where the family home makes up a large part of the estate.

This article explains what Inheritance Tax is, what it applies to, and how the charges are worked out on death. By the end, you will understand what counts as your estate, the difference between what happens when you die and gifts made in your lifetime, who deals with the paperwork, and a straightforward worked example so you can see the numbers in context.

This article explains what Inheritance Tax is, what it applies to, and how the calculation works when someone dies. You will also see how lifetime gifts fit into the system, who deals with the paperwork, and a straightforward worked example so you can see the numbers in context.

So, what exactly is Inheritance Tax and what does it actually tax?

IHT is charged on transfers of value. In broad terms, a transfer of value is something that reduces the value of what you own. In many practical cases this will also improve someone else’s position, but the key legal test is the reduction in the value of your own estate. That concept matters because it means IHT is not just a tax on what your will says. It might also apply to gifts you make during your lifetime, and to situations where you try to give something away but still keep the benefit.

When someone dies, the law treats them as making a transfer of value immediately before death, equal to the value of their estate at that time. This is why the main Inheritance Tax charge is often described as a tax “on death”, even though the legal mechanism is a “deemed” transfer.

So, what counts as part of your estate?

Your estate is more or less the total value of what you own at the date of death, plus certain assets you may have given away but are still treated as part of your estate under special rules.
The legislation defines the estate concept and the transfer on death charge, but the practical approach is to build up a full balance sheet as at the date of death.

For most people, their estate’s balance sheet might look something like this:

1. List everything the person owned (and certain assets treated as still theirs)
2. Value those assets at market value at the date of death
3. Deduct allowable debts and expenses
4. Apply exemptions, reliefs and allowances to reach the taxable amount

HMRC’s guidance on valuing and reporting an estate is built around this approach, because the estate value drives whether Inheritance Tax is due and what has to be reported.

Typical assets included in an estate

An estate generally includes:

• The home, plus any other property
• Bank accounts, ISAs and other savings
• Investments such as shares and funds
• Personal possessions (for example cars, jewellery, collections and artwork)
• Business interests
• Life insurance proceeds payable to the estate (policies written in trust are usually treated differently)
• Overseas property and investments (whether these are included can depend on your long-term UK residence position - from 6 April 2025, the relevant test is whether you are a long-term UK resident for Inheritance Tax purposes, broadly meaning UK tax residence for at least 10 of the previous 20 tax years. Long term UK residents are within the UK IHT net on worldwide assets, while those who are not long-term UK residents are generally within scope only on UK based assets)

Debts and expenses you can usually deduct

You normally deduct debts the person owed at death, such as:

• Mortgages and secured loans
• Personal loans and credit cards
• Utility bills and other outstanding liabilities

Certain Funeral expenses are also deductible. The detail matters, and the estate should keep evidence of what is being claimed and why.

Jointly owned assets

An asset can pass automatically to the surviving joint owner, but it can still be relevant for Inheritance Tax because the key question is what value leaves the deceased’s estate on death. HMRC’s estate valuation and reporting guidance highlights the need to identify how assets are owned so you report them correctly.

In easier terms:

• Joint bank accounts often pass to the survivor, but you still consider the deceased’s share for Inheritance Tax and reporting.
• Property may be owned in a way that means the deceased’s share passes under the will (tenants in common) or passes automatically (joint tenants). The legal title will usually confirm this.

Inheritance Tax on death and lifetime transfers

Contrary to popular belief, Inheritance Tax is not limited to what the person still owns at death. Lifetime transfers can also affect the total IHT. Although most people experience Inheritance Tax when dealing with an estate after a death, the rules do not only look at what the person owned on the date of death.

To calculate the final position, the legislation makes you consider both:

(1) the value treated as transferred on death and

(2) certain gifts made during lifetime that can reduce the available nil rate band or create their own tax charges.

This is why personal representatives usually ask about gifts and trust planning as part of the estate reporting exercise, even where the will looks straightforward.

What is a “chargeable transfer”?

A chargeable transfer is a transfer of value that falls within the Inheritance Tax rules and is not covered by a full exemption. In simple terms, it is a transfer that counts towards the Inheritance Tax calculation, either immediately or when the rules require it to be brought into account. Transfers which do not fall under chargeable transfers are exemptions. Transfers to a spouse or civil partner (where the conditions are met) and transfers to charity are a few examples of exempt transfer.    

Transfers on death

On death, the law treats the deceased as making a transfer of value equal to their estate immediately before death. This is the main charge you hear about when people refer to the “40 percent inheritance tax”.

Transfers between spouses or civil partners are generally exempt from Inheritance Tax. Where both are long term UK residents, this exemption is effectively unlimited. Where the recipient spouse or civil partner is not a long-term UK resident, the exemption can be restricted and specialist advice is usually required.

Lifetime transfers

Lifetime transfers fall into different buckets. Two of the most common are:

• Potentially Exempt Transfers (PETs): most commonly outright gifts to individuals. There is no immediate Inheritance Tax charge, and the gift becomes fully exempt if the person making the gift survives seven years. Certain transfers into specific types of trust, such as some disabled person’s trusts and bereaved minors’ trusts, can also be treated as PETs. If the donor dies within seven years, the gift can become chargeable and may affect the tax position on death. Where death occurs between three and seven years after the gift, taper relief can reduce the tax on that earlier gift, although it does not restore any used nil rate band
• Chargeable Lifetime Transfers (CLTs): most commonly certain transfers into trusts. These can trigger an immediate Inheritance Tax charge at the lifetime rate (20 percent on the value above the nil rate band at the time).

This matters because when you are dealing with an estate after a death, the executors may need to review gifts made in the years before death.

Gifts that can still affect Inheritance Tax

A common type of lifetime transfer is a potentially exempt transfer, which are outright gifts to an individual which becomes fully exempt if the person making the gift survives for seven years. If they die within seven years, the gift can become chargeable and may affect the tax position on death if that gift exceeds the available nil rate bands of that individual.

There are also rules that prevent you from reducing your estate by “giving away” an asset while still keeping the benefit, also known as gifts with reservation of benefit. A classic example is giving your home to your children but continuing to live there as if nothing has changed. In that kind of situation, the asset may still be treated as part of your estate for Inheritance Tax purposes.

What is the current Inheritance Tax rate?

The standard position is that Inheritance Tax is charged at 40 percent on the value of the estate above the available tax-free allowances. Although 40 percent is the headline rate, it does not apply to the whole estate. In practice, the first step is to work out how much of the estate is covered by the tax-free thresholds (the nil rate bands) and any exemptions or reliefs. Only the balance above those thresholds is charged at the death rate. For most estates, the two key thresholds are the standard nil rate band and, where the conditions are met, the additional residence nil rate band.

The nil rate band and residence nil rate band

Two allowances are particularly important in everyday estate calculations:

Whether the residence nil rate band applies depends on conditions, and it can be reduced for higher value estates. For a beginner overview, the key point is that passing a home to children does not automatically mean you get the extra allowance, but it often does in straightforward cases.

The reduced 36 percent rate where you leave enough to charity

A reduced Inheritance Tax rate of 36 percent can apply if you leave at least 10 percent of your net estate to charity.

How is Inheritance Tax calculated on death?

A clear way to think about the calculation is:

•  Value the estate at death
• Deduct allowable debts and expenses to reach the net estate
• Apply exemptions and reliefs (for example spouse exemption, charity exemption, Business Property Relief where relevant)
• Deduct allowances such as the nil rate band, and possibly the residence nil rate band
• Apply the tax rate to what is left

Who has to pay Inheritance Tax, when is it due?

Usually, the people responsible are the personal representatives, meaning the executors named in the will, or administrators if there is no will. They are responsible for valuing the estate, reporting it to HMRC, and paying any tax due before the estate can be distributed.

If you are dealing with an estate after a bereavement, this can feel like a lot to take on quickly. It is normal to need support from a solicitor, accountant, or probate professional, especially where there is property, business assets, or a history of gifts.

When does Inheritance Tax have to be paid?

Inheritance Tax is normally due by the end of the sixth month after the month of death. Interest can be charged if payment is late.

This is why estates sometimes need to think about cash flow early. You may still be waiting for valuations, or still gathering information, but the payment clock still runs.

Can the estate pay by instalments?

Yes, in certain cases. HMRC allows payment by yearly instalments for particular types of assets, most commonly land and property. The instalment option can also apply to qualifying business interests and to certain shares and securities, which is important where a significant part of the estate consists of a trading business or unquoted shareholdings. This can help where the estate is “asset rich and cash poor”, although interest may still apply on outstanding instalments.

Putting it all into perspective

For the sake of ease in understanding, the example below uses round numbers and assumes there are no reliefs, no complex trust arrangements, and no significant lifetime gifts. This example is intended to just show the mechanics.

Scenario

Rachel dies leaving her estate to her two adult children. Her assets and liabilities at the date of death are:

Assets

• Home: £600,000
• Savings and investments: £250,000
• Personal possessions (car, jewellery, household items): £50,000
  Total assets: £900,000

Liabilities and deductible costs

• Mortgage: £100,000
• Other debts: £20,000
• Funeral expenses: £5,000
  Total liabilities and costs: £125,000

We assume the home is left to her children and the conditions for the residence nil rate band are met.

Step by step calculation

What the numbers mean in plain terms

• Rachel’s estate is worth £775,000 after debts and funeral expenses.
• The first part is covered by tax free allowances. In this example, that is £325,000 plus £175,000.
• The remainder, £275,000, is charged at 40 percent which amounts to £110,000.

Comparison: what if the residence nil rate band did not apply?

If the home was not left to direct descendants, or the conditions were not met, the estate would usually only have the £325,000 nil rate band (ignoring any transferable allowances). The taxable amount would then be:

Net estate £775,000 - £325,000 = £450,000 taxable
Tax at 40 percent = £180,000

That is a £70,000 difference in this simple example, which shows why the residence nil rate band can be significant, but also why it is worth checking the conditions carefully.
