Inheritance Tax (IHT) is a tax on the estate (property, cash, savings, investments, and belongings) of someone who has died. In the UK, this tax applies only if the estate exceeds a certain value called the Nil-Rate Band (NRB), which is currently £325,000. Any amount above this is taxed at 40%. https://clarkwell.co.uk/inheritance-tax-second-parent-uk-rules/
