Inheritance tax or “IHT” is still a “voluntary” tax if you plan for it carefully and far enough ahead. What is great about IHT is that you do not have to rely on dodgy artificial tax schemes to avoid it, as there are a number of legitimate ways to avoid it built into the tax. However, if you fail to plan for IHT, you could find that your family is left with far fewer assets than you wanted.

The IHT rules are complicated, so it is best to seek inheritance tax advice to help you understand the position and take advantage of legal ways to avoid IHT.

Of course, you may prefer 40% of your estate to end up with the Chancellor knowing he or she will spend it on catastrophic government IT and transport projects but if you would rather that wealth went to your heirs then read on.

What is Inheritance Tax Planning?

Inheritance tax is a tax on the value of a person’s worldwide estate (i.e., their property, money and possessions) when they die. In certain cases, it may also be charged on large lifetime gifts (see below). Persons with a non-UK domicile will usually only pay IHT on their UK assets unless they are deemed to have become domiciled in the UK.

From 6 April 2025, IHT will charge based on long-term UK residence instead of domicile (see below).

Do you have to pay inheritance tax on jointly owned property?

For inheritance tax on unmarried couples, the liability to pay inheritance tax on assets owned jointly with another person to whom you are not married or in a civil partnership will depend on whether you and your co-owner own the property as “joint tenants” or “tenants in common”, and whether there’s a will.

Inheritance Tax Planning Rates Explained

The rate of IHT depends on the value of a person’s estate. The value is based on the assets (cash in hand and cash in the bank, investments, property or business, vehicles, payments from life insurance policies etc), less any debts and liabilities such as mortgages.

Normally IHT is not payable if either:

  • The value of your estate is £325,000 or less; or
  • You leave everything over £325,000 to your spouse, civil partner, a charity or a community amateur sports club.

If neither of these applies, your estate will be taxed at 40% on anything above the £325,000 threshold when you die (or 36% if you leave at least 10% of the net value to a charity in your will).

However, this £325,000 tax-free threshold might be higher depending on your circumstances – in some cases as high as £500,000, or even £1 million (see below).

Who pays Inheritance Tax?

IHT is normally paid by your executors or personal representatives after you die out of the assets in your estate before the remainder can pass to your family or heirs.

What are some of the main Inheritance Tax exemptions?

  • the ‘nil-rate band’ of £325,000
  • but if you’re leaving your home to your direct descendants, e.g., children or grandchildren, the basic allowance of is £325,000 but to that, you add the ‘residence nil rate band’, which is 2020/21 was £175,000 so that no inheritance tax is charged on the first £500,000 of the estate (£325,000 + £175,000) but this £175,000 main residence allowance only applies though if the estate is worth £2 million or less and in excess of this you lose £1 for every £2 of value above £2 million
  • assets left to a spouse or registered civil partner, provided they’re living in the UK, are exempt from inheritance tax
  • plus the surviving spouse’s inheritance tax allowance rises by the percentage of the allowance that the deceased spouse didn’t use which means that together a couple can currently leave £1,000,000 tax-free
  • farms, businesses and woodlands also attract IHT relief, although these reliefs are being restricted from 6 April 2026 by capping the exemption at a combined £1m and then taxing the excess at 20%.

What is IHT business property relief?

Business property relief reduces the value of a business or its assets when working out how much Inheritance Tax has to be paid.

Currently, 100% business property relief is available for:

  • A business or interest in a business
  • Shares in an unlisted company

50% business property relief is available for:

  • Shares controlling more than 50% of the voting rights in a listed company
  • Land, buildings or machinery owned by the deceased and used in a business they were a partner in or controlled
  • Land, buildings or machinery used in the business and held in a trust that it has the right to benefit from

The deceased must have owned the business or asset for at least 2 years before death.

From 6 April 2026 however the business property relief will be capped at £1m (this value is combined with the value for any available agricultural property relief) and the excess value taxed at 20% with the tax payable in interest free instalments over 10 years.

What is Quick succession relief (QSR)?

QSR is intended to reduce the liability to Inheritance Tax (IHT) where a person dies and their taxable estate includes assets received within the previous five years under an earlier transfer on which tax was (or becomes) payable.

QSR is given by reducing the tax payable on the person’s death estate by reference to the amount of tax on the earlier chargeable transfer, the benefit to the deceased on that transfer, and the period between that transfer and the death.
