Grantanow ^ Mainly because they are being conned by the very well off lobby that stands to gain massively from no IHT. It would be easy to adjust the threshold annually so that ordinary people with houses rising in value did not pay.^
Actually, as someone has already pointed out, it is not those, like me, whose estate will pay IHT, who are opposed to IHT. I, have never opposed it, ithas always struck me as a reasonable and sensible tax.
The people who most oppose it - see this thread, are those who might have to pay it unless the current exclusion amount is raised.
Personally, I would like to see a much more regressive IHT, where estates become liable for IHT at a much lower level, say around £100,000, but where the rate for the first £100,000 over that is set at 10%, for the next £100,000 it will go up to 20% and so on so that the top rate of 40% only comes in at £500,000, but many more pay IHT, but at lower levels.
