Inheritance tax does need reform. The very wealthy have too many options to avoid it whilst the ones whose main asset is their house, which they bought out of already taxed income, pay full whack.

For the 2021/2022 tax year, it is possible for a married couple, or couple in a civil partnership, to pass on up to £1 million in inheritance without paying inheritance tax. Therefore, IHT is only really of concern to the relatively wealthy. However, it is precisely these relatively wealthy people that pay the lion’s share of the IHT collected by the government each year.
HMRC statistics show that those with estates worth between £2 million and £3 million paid an average of 20% inheritance tax in 2015-2016. Over the same year, those with estates worth in excess of £10 million paid an average of just 10%.
Then there are the cases of the mega-rich managing to avoid IHT completely. For example, when the sixth Duke of Westminster died a few years back, he handed on £8.3 billion in inheritance to his heir, without paying IHT. How did he do it? Through a trust.
