"In my view carelessness can be equated with "negligent conduct" in the context of discovery assessments undersection 29 Taxes Management Act 1970 . In that context, negligent conduct is to be judged by reference to the reasonable taxpayer. The test was described by Judge Berner in Anderson (deceased) v Revenue and Customs Commissioners[2009] UKFTT 206 at [22], cited with approval by the Upper Tribunal in Colin Moore v Revenue and Customs Commissioners[2011] UKUT 239 (TCC) : "
" Drawing from a first tier tribunal case Barbara Hackett v HMRC [2012] TC01817 , the judge stated a suspension condition must be "something more than just a basic requirement that tax returns should be free from careless inaccuracies ."
" Now that you are aware of the need to report your income on your self assessment tax return, I would expect all future returns to avoid a similar inaccuracy. "
