UK Inheritance Tax 2025/26

IHT is charged at 40% on estates above the nil-rate band of £325,000. If you leave your main home to direct descendants, you also get the residence nil-rate band of £175,000 — giving a combined threshold of £500,000.

Married couples and civil partners can transfer unused nil-rate band to the surviving spouse, potentially doubling the threshold to £1,000,000. Gifts made more than 7 years before death are exempt.
