AH2110 - Appeals Handbook - ITSA Appeals: Assessments, Amendments and Enquiries: Appeal against a closure notice or a HMRC amendment of a self-assessment made by a closure notice


TMA70/S31(1)(b) grants the right of appeal against a conclusion stated by a closure notice issued by HMRC and against an amendment made by HMRC on completion of an enquiry into a return. The appeal must be made within 30 days following the date on which the closure notice was issued. The normal procedures for appeals and postponements apply and the guidance at AH0100 and subsequent paragraphs should be followed.

It is likely that the difference between the taxpayer and HMRC view of the amount of the final self assessment will reflect areas of dispute arising during the enquiry. Any appeal hearing will therefore be contentious. The onus of proof will remain on the taxpayer to show that HMRC amendment to the self assessment is incorrect (AH2130 and AH2135).

On the determination of the appeal, the Commissioners may

  • reduce an amendment to a self assessment or discovery assessment made by HMRC, or
  • confirm the self assessment, or
  • increase the self or discovery assessment.

The Commissioners’ decision is final subject to the taxpayer’s and HMRC’s right to appeal to the High Court on a point of law (see AH1500 and subsequent paragraphs).

During the course of the enquiry you may have made a jeopardy amendment which may still be under appeal. You should ensure that the appeal against the jeopardy amendment is determined at the same time as any appeal against a HMRC amendment made at the conclusion of the enquiry.

An amendment following the settlement of an appeal against a HMRC amendment (whether by the Commissioners or by agreement under TMA70/S54) should be classified as a HMRC amendment.
