Inheritance tax is not widely understood, perhaps not surprisingly because few of us like to think about what will happen when we die.

However, with a little knowledge and advance planning, you can make a significant impact on how much of your estate you can leave to your loved ones.

Sky high house prices in many areas of the country, combined with a tax threshold that has been fixed for 15 years, mean that more people than ever are finding themselves and their loved ones facing an inheritance tax bill. In fact, it is estimated that HMRC is on track to collect a record £7.8 billion in inheritance tax in the 2023/24 tax year alone, up from the previous record of £7.1 billion in the 2022/23 tax year.

Here, we explain how inheritance tax works, and what you can do to minimise any potential liability.

Inheritance tax laws: What you need to know

Inheritance tax is charged on the value of your assets above a certain threshold when you die. It can also apply to some specific gifts and transfers made during your lifetime.

The current inheritance tax threshold, called the ‘nil-rate band’, has been set at £325,000 since April 2009 and any assets over and above this amount are subject to tax of 40%. The inheritance tax threshold will be frozen at its current level until April 2028.

To work out the value of your estate you should work out the value of all the assets you own. These include:

  •  Your house and any other properties you own
  •  Any savings or investments (some types of pensions are excluded from your estate, but other investments, including ISAs, are taxable)
  • Any other assets
  • The value of any life insurance policies in your name
  • Any gifts (excluding those which are exempt from inheritance tax, or those made to a spouse or civil partner that have been made within the seven years preceding the date of death (obviously you won’t usually know when this is, so it’s worth including any gifts you’ve made within the last seven years).

Then subtract any outstanding debts you have, such as mortgages, credit cards and loans. You can also deduct charitable donations you’re planning to leave in your will along with reasonable costs for your funeral. Certain business and agricultural assets also qualify from relief from Inheritance Tax, so always seek professional advice to help you calculate any potential liability.

Example – Penny has savings of £50,000 and owns property worth £375,000 when she dies. Her estate is therefore worth £425,000. After subtracting her nil rate band of £325,000, Penny’s taxable estate is reduced to £100,000. Her estate will then need to pay tax of 40% on this, resulting in a total tax bill of £40,000. This example assumes she doesn’t have any direct descendants and cannot therefore make use of the main residence allowance (explained below). If she had made use of her annual £3,000 gift exemption both in the year she died and the preceding year, her estate could have been reduced by £6,000, reducing her Inheritance Tax liability by £2,400 (40% of £6,000).

Marriage and inheritance tax

If you’re married, or have a civil partner, you can leave your entire estate to your spouse or partner free of inheritance tax. The good news is that transfers between spouses like this do not use up any of your nil rate band and in fact, your unused nil rate band can be transferred to your spouse or civil partner. For example, if your spouse left everything to you before they died, you’d typically have a larger estate when you die, but you could potentially also have a nil-rate band of £650,000 applied to the value of your estate – your own £325,000 nil rate band, combined with the transfer of your partners £325,000 nil rate band.

The main-residence allowance explained

A relatively recent addition to the already complicated nature of inheritance tax is what’s known as the main residence allowance. This allowance applies in addition to the existing nil rate band, but only where the person who has died is transferring a property that was once their home, to their direct descendants (for example their children or grandchildren). The residence nil-rate band is currently £175,000, having increased to this limit in April 2020.

You can transfer this extra allowance to your surviving spouse when you die if you haven’t already used it. This means that in the current tax year, a married couple could potentially leave their children a combined estate of up to £1m, without facing an inheritance tax bill.

There are a number of situations where the main-residence allowance will not be of benefit. Specifically it won’t help you if you don’t own a property or if you sold your property before 8 July 2015 because for example, you moved into residential care or are living with your children. It also won’t help if you don’t have any direct descendants, so for example, if you wish to leave your home to a niece or nephew. At the top end of the spectrum, those with large estates will see the main-residence band reduce by £1 for every £2 by which the estate exceeds £2 million. At the other end of the scale, those with a property worth less than £175,000 per person, or £350,000 per couple, will only benefit to the value of their house.

The importance of writing a will

The most important thing you can do in your lifetime to ease the pain for your friends and family when you die is to write a will. This should detail what you want to happen to your assets and personal possessions after you die. It can also specify critical things such as who you would want to be the legal guardians of your children, or grandchildren if you have parental responsibility for them.

Give yourself peace of mind that you’ll have control over what happens to your money and property when you die. A legally-binding will can ensure your wishes are followed and avoid complications for your loved ones at a very difficult time.

If you’re a business owner, you’d usually make a specific gift of your business in your will, so that it goes to who you want it to. If you don’t do this, your Inheritance Tax bills are likely to be bigger than necessary.

Writing a will is therefore of critical importance for a number of reasons, but could also have a significant bearing on how much inheritance tax your estate has to pay. For more information, please see our guides on The importance of writing a will and guidance on How to write a will.
