Income tax – Assessment. The discovery assessments at issue made pursuant to s 29 of the Taxes Management Act 1970 by the Revenue and Customs Commissioners (HMRC) in relation to the taxpayer's self-assessment tax returns, had been validly made. Further, the penalty determinations made by HMRC pursuant to s 95 of that Act and Sch 24 to the Finance Act 2007 were valid and had been set at an appropriate level. Consequently, the First-tier (Tax Tribunal) dismissed the taxpayer's appeals against those assessments and penalties.
