Once upon a time, death duties affected only the rich. One or two very rich people could happily be punitively taxed without any risk of losing votes. Also, in the days of exchange controls, there was very little that people with assets in the UK could do to avoid tax.
Nowadays, things are very different. There are no exchange controls and those with money can move it anywhere in the world, indulging in a bit of revenue arbitrage. Death duties, or Inheritance Tax as it is now called, have become much more democratic. With the Nil Rate Band currently set at £300,000, even those who do not read the Daily Mail have come to realise that they may struggle to pass on their wealth to their heirs.
This problem has been compounded by the fact that much of this wealth is in the family home and the value of granny’s semi has shot up over the last twenty years. Also, retired people are now the first generation of the property owning democracy, their parents will often not have owned a home. All of which makes this a very emotional topic.
The very rich do not pay much tax these days, often because they can afford to give much of it away well before they die, avoiding IHT. If you happen to live in your wealth or need it to live on, that option is hardly open to you. The financial world, particularly, the life insurance industry, has exploited this by marketing schemes to allow people to have their cake and eat it, using trusts and insurance in combination. From a cynical perspective, one of the reasons why some of these schemes work at all was that the charges ate away at the wealth, reducing the value of the estate. The trouble is that many of these schemes have been banned by the Government, often retrospectively, causing more and more prime voters to worry about passing their money on.
In many ways, IHT is quite fair. Families are evened out a little on death and taxes on those working are kept down, helping to reward those not born to an inheritance. The trouble is that the tax system has rarely been successful at this type of social engineering, partly because voters will not wear it. We all aspire to do well and hope for the same for our families. IHT also distorts behaviour, often negatively, and the main problem is that for ‘Middle England’ much of the money is in the house. It is not always desirable or practical to trade down to release the capital. Someone living in a £400,000 house in London can hardly trade down very far without moving away.
It also means that people will have to decide whether to give wealth away. All very well if you are sitting on Millions but more problematic for smaller sums when the future is full of uncertainty over life expectancy, health, nursing care, etc.
Perhaps it would be better to merge IHT in the Capital Gains Tax regime, as it is in many countries. Many investments, such as the home, could be exempt and there would be no need to give money away before death. Initially, at least, less may be raised but I am sure a way will be found to plug the gap. Whether we end up disliking that more is another matter.
