IHTM04044 | Transfers on death: what is the value transferred on death?
From HM Revenue & Customs · Inheritance Tax Manual
The starting point is the value of all the property that makes up the person’s estate (IHTM04029) less the value of deductible liabilities (IHTM28010). The rules about the valuation of property (IHTM09701) and the deduction of liabilities (IHTM28002) are covered in other sections, but there are some special rules that effect the value of the estate on death. These are that
in valuing property in the death estate, the estate has to be considered in it’s entirety, so items of property may be taken together (IHTM04045) even though they may be held under separate titles,
although the deemed transfer takes place immediately before the death, certain changes in value caused by the death (IHTM04046) are taken into account,
the value of certain categories of property is left out of the account, (IHTM04331)
