“become aware of the failure less than 12 months after the time when tax first becomes unpaid by reason of the failure”
“1. It is the Respondents’ contention that the tax first becomes unpaid on the first day of the period over which the potential lost revenue is calculated. In making this contention the Respondents would refer the Tribunal to Paragraph 6 [note: should be 7(6)] of Schedule 41 FA2008 which states: “In the case of any other relevant obligation relating to value added tax, the potential lost revenue is the amount of value added tax (if any) for which P is, or but for any exemption from registration would be, liable for the relevant period (see sub-paragraph (7)) but subject to sub-paragraph (8).”
“in relation to a failure to comply with an obligation under any other provision, the period beginning on the date with effect from which P is required in accordance with that provision to be registered and ending on the date on which HMRC received notification of, or otherwise became fully aware of, P’s liability to be registered.”
