CH190500 | Publishing details of deliberate tax defaulters: what is a deliberate tax default
From HM Revenue & Customs · Compliance Handbook
A deliberate default is when a person has incurred a penalty for a deliberate, or deliberate and concealed
inaccuracy in a return or other document,
failure to comply with certain obligations to do something, or
VAT or Excise Duty wrongdoing.
These are relevant penalties and they are explained in more detail at CH190640+.
In this guidance, we refer to any inaccuracy, failure, omission or wrongdoing that gives rise to a relevant penalty as a deliberate default. We call a person who incurs a relevant penalty a deliberate defaulter.
