“31. The “situation” referred to in subsection (4) is a reference to what has been described as an “actual insufficiency” in the amounts charged to tax (see [33] to [34] of the judgment of Auld LJ in Langham v Veltema[2004] STC 544 , which considered the meaning of “the situation” in the context of s.29(5)) or the “fact of the undercharge” in Hargreaves v HMRC[2014] UKUT 0395 (TCC) (“Hargreaves UT”) at [21(6)]). The “situation mentioned in subsection (1)”, therefore, is not a reference to HMRC’s making of the discovery, as specifically confirmed in Hargreaves UT at [21(6)]. … 32.

It follows, therefore, that s.29(4) is asking whether the “fact of the undercharge” was brought about by a taxpayer’s careless or deliberate conduct: … the amount of the undercharge, are not relevant.”
