Nil-rate band
Everyone gets a £325,000 nil-rate band. Married couples can combine unused allowances, giving up to £650,000 before IHT applies.
Residence nil-rate band
An extra £175,000 when you leave your main home to children or grandchildren. Can be doubled for widows and widowers — up to £350,000.
7-year gift rule
Gifts made more than 7 years before death are fully IHT-free. Gifts in years 3–7 benefit from taper relief reducing the tax charge progressively.
Spouse exemption
Transfers between spouses or civil partners are fully exempt from IHT — no limit. The survivor inherits unused nil-rate bands from the deceased.
Inheritance tax threshold UK 2025 — complete guide
The UK inheritance tax (IHT) nil-rate band is £325,000 per person in 2025/26, unchanged since 2009. Everything above this is taxed at 40%. If you own a home and leave it to direct descendants, an additional residence nil-rate band of £175,000 applies — giving a single person a potential £500,000 allowance before any IHT is due.
Married couples and civil partners can combine allowances on the second death, giving up to £1,000,000 before IHT applies. Many estates that initially appear taxable pay no tax once all allowances are correctly applied.
The residence nil-rate band tapers for estates over £2,000,000 — reducing by £1 for every £2 above this threshold. Leaving at least 10% of your estate to charity reduces the IHT rate on the remaining taxable amount from 40% to 36%.
How to reduce inheritance tax legally
Legal strategies include: regular gifts from surplus income (immediately exempt), larger gifts which become tax-free after 7 years, writing life insurance in trust, maximising pension assets (generally outside the estate), charitable giving, and establishing trusts. Professional advice identifies the most effective combination for your specific circumstances.
Inheritance tax FAQs
How much inheritance tax on a £500,000 estate?
If single with no property: NRB is £325,000, tax is 40% × £175,000 = £70,000. If you own property and have children: NRB £325,000 + RNRB £175,000 = £500,000 allowance, so no IHT at all. If widowed with children and property, the combined allowance can reach £1,000,000 — again, no IHT.
Do I pay inheritance tax on a property?
Property forms part of your estate for IHT. However, leaving your main home to direct descendants (children, grandchildren) triggers the residence nil-rate band (£175,000), which can reduce or eliminate IHT. Any outstanding mortgage reduces the property value for IHT purposes.
Do spouses pay inheritance tax?
No. Assets passing between married couples and civil partners are completely exempt from IHT regardless of amount. The surviving spouse also inherits any unused nil-rate band, effectively doubling available allowances on the second death.
How does the 7-year gift rule work?
Gifts made more than 7 years before death are completely IHT-free. Gifts made 3–7 years before death benefit from taper relief: 80% reduction at 3–4 years, 60% at 4–5 years, 40% at 5–6 years, 20% at 6–7 years. The annual exemption (£3,000/year) is immediately exempt regardless of timing.
What is the UK inheritance tax rate?
The standard UK IHT rate is 40% on the estate value above the nil-rate band. If you leave at least 10% of your net estate to charity, the rate on the remaining taxable estate reduces to 36% — potentially saving a significant amount on large estates.
