Yeah of course, get all that. I mentioned Mansion Tax is the same post, which was perhaps confusing.
But back to IHT, for me it's a matter of principle. You either think it is morally right for the state to take money off people when they die, depriving their airs of money that their parents presumably wanted them to have, or you don't. I am in the latter camp. You live your life and pay your taxes, and that should be the end of it IMO. I don't think it's right that when you die the state should say great we can now have even more of that money you've accumulated. Even worse, to change the rules on people AFTER they have made all of their life choices. The holidays they didn't take, the car they didn't buy, the house move they didn't do, so they can give money to their kids and give them a leg up in life. Only to find that Rachel Thieves says thanks very much, glad you've accumulated that cash, we'll have some more of that (laughing as she does it).
So I am not in favour of their being any IHT at all, let alone a reduction in the tax exempt limits.
