Inheritance tax, this has effectively increased year on year with house inflation anyway. It also mostly affects those that have savings and assets built up after already paying tax. So people end up being taxed twice on the same earnings. Its an awful tax that needs abolishing or at least having its threshold raised significantly.
Why would it need raising? It affects something like 4%-7% of estates.
If it was abolished, half the total savings would go to the top 1% of the population.
It's currently targeted at the very richest people in society. Why on earth would they be the people we target with a tax cut?
