My Mum died in October, and I think I have finally found all of her bank accounts, premium bonds and investments. I’m aware that I should benefit from my father’s unused IHT threshold and 2 x £175,000 for the house, but there doesn’t seem to be any way of entering this on the gov.uk website. With these allowances, I should be well under the IHT threshold, but without them, the bill looks huge. How can I ensure that this is taken into consideration? I’ve got all of my Dad’s paperwork from probate. Would it be best to file for probate on paper rather than online? It’s complicated by the fact that I am working overseas until next summer, and in a different time zone, so haven’t managed to get hold of the IHT helpline yet. Or should I just pay someone to deal with it all?
