“ … In the case of a discovery, the officer must believe there to be – rather than merely suspecting – an insufficiency of tax. “Belief” sets a higher bar than mere “suspicion” (see Jerome Anderson v HMRC[2018] UKUT 0159 (TCC) at [28] …)”
“I find that the requirement for the suspicion to be based on “reasonable grounds” means that this suspicion must have an objective basis. In order for HMRC to meet the burden of proof as regards Condition B, not only must they share the grounds for their officer’s suspicion, but they must provide evidence demonstrating that the officer is entitled to have that suspicion and that it is objectively reasonable for him or her to have it.”
