Inheritance Tax

County1950fan

Clarification please. If the estate is made up of £750,000 cash and £180,000 house, would there be tax to pay as the cash element is over the 2X £325,000 rolled over nil rate exemption.

Probably Yes.

Estate is £750+180k =  £930k (less funeral and any other debts)/

NRB £325k x 2 = £650k + £180k Residential Nil Rate (value of house not 2 x £175k that is allowed) = £830k

IHT payable on £100k = £40k from the cash by Executor(s).

Unless of course that cash money is in part from downsizing to £180k home from more expensive house.  When, I believe the up to £350k figure might apply.
See https://www.gov.uk/guidance/how-downsizing-selling-or-gifting-a-home-affects-the-additional-inheritance-tax-threshold#downsizing-to-a-less-valuable-home for the 'horse's mouth' version.
