ECH21055 - Penalties: Abatement Structure


The abatement structure is designed to arrive


  • at an accurate judgement of the appropriate amount of penalty
  • where that penalty is expressed not as a fixed amount but
  • as a maximum, that is, an 'amount not exceeding'.

The procedure is to start with the maximum penalty and then reduce it by the appropriate percentages for


  • the extent of employer's or contractor's disclosure of irregularity ECH21065 and ECH21070
  • the extent of employer's or contractor's co-operation throughout the review ECH21075 and ECH21080
  • the seriousness of the offences established by the review ECH21085 and ECH21090.

The statutory basis is Section 100(1) TMA 1970.

The abatement structure is how HM Revenue & Customs computes the appropriate penalty, in a negotiated settlement.

ECOs should


  • never forget that if it comes to a formal determination, any penalty can be appealed and the Commissioners can review our judgement: Section 100B(2)(b).
