Inheritance tax rules UK can be complex, but understanding the key thresholds and planning opportunities is essential for protecting your estate and minimising tax liabilities.
Inheritance tax (IHT) is a tax on the estate of someone who has died. Estate includes property, savings, investments, personal possessions and certain gifts they made during their lifetime. If the total value of someone’s estate exceeds the available tax free threshold, the excess is normally taxed at a flat rate of 40%. A reduced rate of 36% applies if at least 10% of the net estate is left to charity.
The executor of the will (or the administrator if there is no will) is responsible for calculating and paying inheritance tax to HM Revenue and Customs from the estate’s funds. Beneficiaries usually receive their inheritance net of tax and do not personally pay the inheritance tax bill.
Only 5% of estates currently pay inheritance tax, which means most families will not face a liability. However, with the inheritance tax threshold frozen since 2009 and property values continuing to rise, more estates are being pulled into the IHT net each year. The Office for Budget Responsibility forecasts IHT will raise approximately £8.7 billion in 2025-26.

UK Inheritance Tax Thresholds: Nil Rate Band and Residence Nil Rate Band
Understanding how the two main thresholds interact is essential to working out any potential inheritance tax liability. Here is how they break down for the 2026/27 tax year:
- The inheritance tax nil rate band is £325,000 per person. This is the baseline tax free allowance below which no inheritance tax is payable. It has been frozen at this level since April 2009, and the government has confirmed it will remain frozen until at least April 2031.
- The residence nil rate band is £175,000 for 2026/27. This additional allowance applies when a main residence passes to direct descendants such as children, stepchildren or grandchildren. The threshold can increase to £500,000 per individual when the home passes to descendants.
- The residence nil rate band tapers if the estate value exceeds £2 million, reducing by £1 for every £2 above that figure. For estates worth more than £2.35 million, the residence nil rate band disappears entirely.
- Both bands can normally be transferred between a spouse or civil partner. If the first spouse to die does not use their full allowances, the unused nil rate band and unused residence nil rate band can pass to the surviving spouse. This means a couple can leave up to £1 million tax free combined.
- The transfer must be claimed within two years of the second death, and only married couples or civil partners can transfer allowances. Unmarried partners cannot benefit from this transfer.
Who Pays Inheritance Tax and When Is It Due?
The personal representatives, whether executors named in a will or administrators appointed under intestacy, carry the responsibility for valuing the whole estate and paying inheritance tax (no-follow). They must submit the relevant HMRC forms and settle any tax before distributing assets to beneficiaries.
A practical checklist for personal representatives:
- Value the estate (property, bank accounts, investments, personal possessions)
- Deduct debts, liabilities and funeral expenses
- Apply available thresholds, reliefs and exemptions
- Calculate IHT on any excess
- Submit returns to HMRC
- Arrange payment from estate funds
Inheritance tax must normally be paid by the end of the sixth month after the person’s death. If payment is late, interest accrues from that point. In some cases, particularly where the estate includes land, a business, shares or agricultural property that is difficult to sell quickly, HMRC may allow payment by instalments over up to 10 years.
Inheritance Tax Rules UK for Spouses, Civil Partners and Co-habiting Couples
The inheritance tax rules UK provide significant advantages to those who are married or in a civil partnership. Here is how the treatment differs depending on relationship status:
- Assets left to a UK-domiciled spouse or civil partner are exempt from inheritance tax, regardless of value. Spouses inherit tax free, which means no IHT is due on the first death if everything passes to the surviving partner.
- Any unused inheritance tax allowance from the first death can be transferred to the surviving spouse or civil partner. This includes both the nil rate band and the residence nil rate band. The transfer must be claimed within two years of the second death.
- Cohabiting partners, no matter how long they have lived together, do not benefit from the same automatic inheritance tax exemptions or transferable allowances. Without a valid will, an unmarried surviving partner may inherit nothing at all under the intestacy rules.
Example: A married couple each own assets worth £450,000. When the first spouse dies and leaves everything to the surviving partner, no IHT is due. The surviving spouse later dies with a combined estate of £900,000. With both nil rate bands (£650,000) and both residence nil rate bands (£350,000), the total tax free threshold reaches £1 million. No inheritance tax to pay.
An unmarried couple in the same position would face IHT on the first death, and the survivor could not claim the deceased partner’s unused allowances. Read our guide to Unmarried Couples Property Rights for more information.
How Inheritance Tax Works for Gifts & Lifetime Transfers
Understanding how inheritance tax gift rules UK operate can open up valuable planning opportunities. Here are the key principles:
- A lifetime gift to an individual is treated as a potentially exempt transfer (PET). Lifetime gifts may be exempt from IHT if the donor survives for seven years after making them. If they do, the gift falls entirely outside the estate.
- If the donor dies within seven years period, the gift is counted back into the taxable estate. Gifts made within seven years of death may incur inheritance tax, potentially using up part or all of the nil rate band and increasing the tax on the rest of the estate.
- Taper relief may reduce the IHT rate on taxable gifts made within seven years but only where the gift exceeds the nil rate band. The relief reduces the tax payable, not the value of the gift itself.
Taper Relief Scale
| Years Between Gift and Death | % of Full Tax Payable | Effective IHT Rate |
| Less than 3 years | 100% | 40% |
| 3 to 4 years | 80% | 32% |
| 4 to 5 years | 60% | 24% |
| 5 to 6 years | 40% | 16% |
| 6 to 7 years | 20% | 8% |
| 7+ years | 0% | 0% (fully exempt) |
Specific Rules for Certain Gifts
Certain gifts to trusts can be chargeable lifetime transfers, immediately taxable if they exceed the nil rate band. Specialist advice is essential before making gifts into trust for IHT purposes.
Gifts with reservation of benefit, for example gifting your family home but continuing to live in it rent free, are normally treated as still part of your estate. HMRC actively challenges these arrangements.
Tax-Free Gifting Allowances and Exemptions
Making gifts during your lifetime, within the recognised inheritance tax exemptions, can steadily reduce the total value of your estate over time. The main HMRC allowances are:
- Annual gift allowance: You can gift up to £3,000 tax free each year. If you did not use the previous year’s allowance, you can carry it forward for one year, giving a maximum of £6,000 in a single tax year.
- Small gifts: Gifts of up to £250 per person, per tax year, to any number of recipients. This cannot be combined with the annual exemption for the same person.
- Wedding gifts: Parents can give up to £5,000, grandparents up to £2,500, and anyone else up to £1,000 as wedding or civil partnership gifts, free of IHT.
- Normal expenditure out of income: Unlimited tax free gifting is possible if the gifts are regular, come from surplus income and do not reduce the donor’s standard of living.
- Charities and other gifts: Gifts to UK-registered charities, community amateur sports clubs and political parties are fully exempt from inheritance tax, whether made during lifetime or on death.
Keep detailed records of dates, amounts, recipients and the reasons for each gift. Without proper documentation, HMRC may challenge whether a gift qualifies for a particular exemption.
Business Property, Agricultural Property and Other Reliefs
Specialist reliefs can take substantial assets outside the IHT net for those who qualify:
- Business Property Relief provides 50% or 100% relief from IHT on qualifying business property, including shareholdings in trading companies and certain partnership interests.
- Agricultural Property Relief can reduce or remove IHT on qualifying agricultural property and land, subject to strict conditions on use, occupation and ownership periods.
- From 6 April 2026, a £2.5 million cap applies to combined qualifying assets that benefit from 100% relief. Any excess receives only 50% relief. Unused allowance for this relief can be transferred from a deceased spouse or civil partner, potentially doubling the cap to £5 million for couples.
- Business and Agricultural Property Relief provides significant reductions in taxable value for qualifying assets, but only where technical requirements are met. Inappropriate investment structures or mixed-use arrangements can jeopardise relief entirely.
Restructuring shareholdings, partnership agreements and ownership of agricultural property well in advance of any transfer can significantly reduce an eventual inheritance tax bill for the next generation.
Property, the Family Home and the Residence Nil Rate Band
The family home is often the most valuable asset in an estate. The residence nil rate band is £175,000 for direct descendants and is designed specifically to help families pass a main residence to the next generation with less tax.
- Leaving a home to children increases the allowance to £500,000 per person when the residence nil rate band is combined with the standard nil rate band.
- If the property value is lower than £175,000, only the actual value is used. If a person downsized or sold their home before death, special rules (the “downsizing provisions”) may still allow some or all of the residence nil rate band to apply.
- Giving away a home during your lifetime and continuing to live in it triggers the gift with reservation rules previously mentioned, meaning the property remains in your estate for inheritance tax purposes.
- How property is owned matters. Holding as joint tenants or tenants in common affects whether the deceased’s share passes automatically to the surviving partner or can be directed to other family members through a will.
- Aligning property ownership, wills and trusts between spouses and civil partners is essential to maximise the use of both residence nil rate bands on the second death.
Pensions, Life Policies and Inheritance Tax
The inheritance tax pension rules are evolving, and the landscape is set to shift significantly:
- Many defined contribution pensions and SIPPs currently sit outside the taxable estate for IHT if set up correctly with named beneficiaries. This makes pensions one of the most tax efficient ways to pass on inherited wealth.
- Pensions will be included in taxable estates from April 2027. From that date, unused pension pots and death benefits may be brought within the estate for inheritance tax purposes, except where they pass to a surviving spouse or civil partner. Transitional provisions may apply, so it is important to seek advice on how these changes affect your position.
- Pension death benefits remain subject to separate income tax rules. Beneficiaries who draw pension benefits after the member’s death may pay income tax depending on the member’s age at death.
- Placing life insurance policies in trust can keep the proceeds outside your estate for IHT, while still providing a lump sum that executors can use to help pay any tax due quickly. Without a trust, a policy payout simply increases the total value of the estate and the inheritance tax liability.
Charitable Giving and Reducing the Inheritance Tax Rate
Charitable giving can serve as a powerful planning tool to reduce inheritance tax liability while supporting causes that matter to you:
- Gifts to charities are exempt from inheritance tax, whether made during lifetime or on death in a will.
- If at least 10% of the net estate is left to a UK-registered charity, the inheritance tax rate on the remainder of the taxable estate drops from 40% to a reduced rate of 36%.
- For example, if the net estate after debts and thresholds is £500,000 and £50,000 is left to charity, the remaining £450,000 is taxed at 36% (£162,000) rather than 40% (£200,000), saving £38,000 overall while also benefiting the charity.
We can help clients balance charitable objectives with family needs and overall tax efficiency as part of a wider estate plan.
How to Calculate an Inheritance Tax Bill in Practice
Here is a step-by-step approach to working out how inheritance tax works UK in a real scenario:
- Total the estate value, including qualifying gifts made within seven years prior to death
- Deduct debts, liabilities and funeral expenses to arrive at the net value
- Apply exemptions (spousal, charity, other gifts)
- Deduct the nil rate band (£325,000) and, if applicable, the residence nil rate band (£175,000)
- Apply the 40% rate (or 36% if the charity test is met) to the excess
- Reduce tax on any lifetime gifts using taper relief where applicable
Example 1 (no home to descendants): A single person dies with an estate of £600,000 and no qualifying residence. After applying the nil rate band of £325,000, the remaining £275,000 is taxed at 40%. Inheritance tax is charged at 40% on estates above £325,000, giving an IHT bill of £110,000.
Example 2 (home to children): An estate of £900,000 including a main residence passing to children. The combined threshold is £500,000 (£325,000 NRB + £175,000 RNRB). The taxable estate is £400,000. At 40%, the IHT bill is £160,000.
There is real scope to reduce the final tax bill by reorganising ownership, using life insurance in trust, making gifts during lifetime and optimising will-based planning, provided expert advice is taken early enough.

FAQs: Inheritance Tax Rules UK
Do I have to pay UK inheritance tax if I live abroad but own UK assets?
Non-UK residents can still fall within the UK inheritance tax net on UK-sited assets such as property or shares, regardless of where they live. If you remain UK-domiciled for inheritance tax purposes, your worldwide estate may also be caught. Anyone with cross-border assets should seek specialist advice to understand their exposure.
Is life insurance subject to inheritance tax?
If a life insurance policy is owned personally and pays into the estate, the proceeds can increase the inheritance tax bill. Writing a policy into trust can usually keep the payout outside the estate and make funds available quickly to help pay any tax due. We recommend reviewing existing policies with a solicitor to confirm whether they are properly held in trust.
How often should I review my will and inheritance tax plan?
Review your will and IHT planning at least every three to five years, and sooner after major life events such as marriage, divorce, a new child or a property purchase. Tax rules change over time, so older wills may no longer make the best use of current allowances. Book a consultation to have your documents reviewed in light of the latest law.
Can I avoid inheritance tax completely by giving everything away?
Simply giving assets away shortly before death will usually not work because of the seven year rule and gifts with reservation. Giving away assets may also trigger capital gains tax or leave you financially vulnerable. Responsible estate planning aims to balance reducing IHT with ensuring your long-term security, and legal advice is essential before making large gifts.
What happens if there is no will when someone dies?
The estate will be distributed under the intestacy rules, which may not match the deceased’s wishes and can create avoidable IHT inefficiencies. Unmarried partners and stepchildren are often left out entirely, causing hardship and disputes. Making a valid, up-to-date will is a key part of effective inheritance tax and estate planning.
