Grants on credit: what are 'exceptional circumstances'?

HMRC will only issue a grant on credit in the most exceptional circumstances. The circumstances where we might do so are:

  • When it is impossible for the Personal Representative (PR) to fund the full amount due from any source - these sources are listed at IHTM05122 .
  • When it is not in the interests of the Exchequer for the issue of a grant to be delayed (IHTM05124).
  • When the PR has made all appropriate enquiries and made all the necessary arrangements to fund the tax due on delivery of the form IHT400 (IHTM10011). The PR becomes aware of an additional asset or information that suggests a different valuation for an asset already included at the last minute (but see IHTM05126).
