I really don't understand the objections or the frenzy to find way to avoid manage it.
My parents are professional people, been frugal all their lives. I have no idea what their financial situation is but I know there are some investments and they own their home in the SE, so should the worst happen, there will be a substantial sum, which AFAIK will go to DSis and I.
My main hope is that they live such long and active lives that it's all spent by the time they go. If they should need it I hope they can pay for good quality care. However, if there is anything left we will get £325k between us tax free. If there's more than that, why on earth shouldn't tax be paid on it?
On the basis that tax has to be raised somewhere, this seems like a relatively painless way to raise it to me. I'm not expecting anything, I haven't earned anything, if I get something, I won't object to paying tax on it.
