“Having considered the evidence of the information provided by HMRC concerning the introduction of the PAYE and NIC penalties, we are of the view that no reasonable employer, aware generally of its responsibilities to make timely payments of PAYE and NIC amounts due, could fail to have seen and taken note of at least some of the information published and provided by HMRC.”
“We do not therefore consider that any failure on the part of HMRC to issue warnings to defaulting taxpayers, whether in respect of the imposition of penalties or the fact of late payment is of itself capable of mounting either to a reasonable excuse or special circumstances.”
“The obligation is to make payment: the lack of warning (or early assessment) of a penalty is not an excuse for failing to make payment.”
