Understanding Inheritance Tax in the UK
Inheritance Tax (IHT) is a levy on the estate of someone who has died. It applies when the total value of the deceased’s assets – property, savings, investments and personal possessions – exceeds a set threshold. The tax is usually paid as a one‑off sum after death, either from the estate itself or, in certain circumstances, from the recipients of gifts made during the last seven years of life.
Current Inheritance Tax Threshold
The basic nil‑rate band for an individual is £325,000. If the estate’s value exceeds this amount and no reliefs apply, the excess is taxed at 40 %. For example, an estate worth £500,000 would incur IHT on £175,000, resulting in a £70,000 tax bill.
Spouses and civil partners can transfer any unused portion of their nil‑rate band to each other. This effectively gives a married couple or civil partnership a combined threshold of £650,000.
Residential Nil Rate Band (RNRB)
Introduced in April 2017, the RNRB provides an additional allowance when a main residence is passed to direct descendants – children, step‑children or grandchildren. As of the 2023/24 tax year, the RNRB adds £175,000 to the individual’s nil‑rate band, raising the potential tax‑free amount to £500,000 per person. For a surviving spouse who inherits the unused RNRB, the combined allowance can reach £1 million.
The RNRB only applies to assets transferred on death; it does not cover lifetime gifts or transfers into trusts made within seven years of death.
Gifting Money Without Triggering IHT
Certain gifts are exempt from inheritance tax if they meet specific conditions:
- Gifts made more than seven years before death are completely outside the IHT net.
- Each tax year you may give up to £3,000 in total to any recipients without incurring IHT. Unused allowance can be carried forward one year.
- Small gifts of £250 or less per person per year are exempt, with no limit on the number of such gifts.
- One‑off gifts for special occasions are allowed: up to £5,000 for a child’s wedding and £2,500 for a grandchild’s wedding.
Care should be taken if you anticipate needing long‑term care, as large gifts made shortly before entering care may be viewed as “deprivation of capital” and could affect eligibility for state‑funded assistance.
Who Pays the Inheritance Tax Bill?
Generally, the estate’s executors settle any IHT liability using the estate’s assets after deducting mortgages, funeral expenses and other liabilities. If the tax arises from gifts made within the seven‑year window before death, the recipients of those gifts are responsible for paying the amount due.
Legitimate Ways to Reduce an Inheritance Tax Liability
Make a Will
A clear, up‑to‑date will lets you decide who receives your assets and can include tax‑efficient provisions. Dying intestate (without a will) means the law decides distribution, which may not be tax optimal.
Transfer Assets to a Spouse or Civil Partner
Transfers between spouses and civil partners are exempt from IHT, regardless of value. This does not apply to unmarried co‑habiting partners.
Leave a Charitable Legacy
Gifts to qualifying charities are free of IHT. Moreover, if at least 10 % of the net estate is left to charity, the IHT rate on the remainder can be reduced from 40 % to 36 %. Resources such as Rememberacharity provide guidance on setting up charitable legacies.
Invest in AIM Shares
Shares listed on the Alternative Investment Market (AIM) currently qualify for 100 % IHT relief if held for more than two years. This relief is scheduled to change to a 20 % rate after April 2026. Because AIM shares can be complex, it is advisable to consult an independent financial adviser – directories like Unbiased – or a tax specialist from the Chartered Institute of Taxation before investing.
Use Trusts
Placing assets into a trust can mitigate IHT. A typical arrangement involves paying 20 % IHT on amounts exceeding the nil‑rate band when the trust is created, then a 6 % charge every ten years, and a further 6 % when assets leave the trust upon death. This can lower the effective rate from 40 % to around 32 % over a typical period. Trusts are especially useful for protecting assets for children from a previous marriage or for managing property income after remarriage. Professional advice is essential; the Society of Trust & Estate Practitioners (STEP) can help locate qualified experts.
Future Outlook for Inheritance Tax
The statutory nil‑rate band has remained at £325,000 for several years, while property values – particularly in southern England – have continued to rise. Consequently, more estates are likely to exceed the threshold, leading to higher IHT liabilities for many families. Monitoring changes to the RNRB and any potential adjustments to the nil‑rate band will be important for effective estate planning.
How to Help Your Family Minimise IHT
Start by reviewing your will and ensuring it reflects your current wishes and tax‑efficient strategies. Consider making use of annual gift allowances, exploring trusts or AIM investments where appropriate, and discussing charitable legacies if they align with your values. Because each situation is unique, seeking guidance from a qualified financial adviser or tax professional is strongly recommended to tailor a plan that preserves as much of your wealth as possible for your loved ones.
