IHTM37080 | Non - Land valuation cases: contentious issue cases
From HM Revenue & Customs · Inheritance Tax Manual
Where negotiations have stalled because of a contentious issue or disagreement over the interpretation of the law, rather than a valuation, HMRC will consider issuing a Notice of Determination (NOD) to resolve the dispute
Taking the Litigation and Settlement Strategy into account, HMRC will consider whether
sufficient is at stake in principle or tax or both to justify a NOD and any subsequent appeal hearing
there is any prospect of persuading the taxpayer to accept HMRC’s position or of achieving an early practical reconciliation; and
a NOD would not prejudice investigations taking place in any other case, or elsewhere in HMRC.
