Statistics from the UK government’s tax office show the amount of Inheritance Tax (IHT) families are paying has soared from £2.9 billion ($3.9 billion) in 2011-12 to £5.2 billion ($7.1 billion) in 2019-20—this in part reflects the rise in asset values since 2008, and in particular skyrocketing property prices in London and the south-east of England.
