How Inheritance Tax Works: Thresholds, Rules and Allowances
How Inheritance Tax applies to an estate
Inheritance Tax is a tax on the estate of someone who has died. An estate includes their property, money and possessions. Funds from the estate are used to pay Inheritance Tax to HM Revenue and Customs.

When gifts can be taxed
People who receive gifts from you might have to pay Inheritance Tax, but only if you give away more than £325,000 and die within 7 years.
