Under section 230 of the Income Tax Act (“ITA”) and section 286 of the Excise Tax Act (“ETA”) all taxpayers must keep records that are adequate to determine the amount of taxes owing. When these sections are complied with and a taxpayer maintains adequate records, the Canada Revenue Agency (“CRA”) will generally rely on those records when conducting an audit to determine the taxpayer’s tax obligations. However, if a taxpayer does not maintain adequate records, the CRA can use alternative assessment methodologies to assess a taxpayer under subsection 152(7) of the ITA and subsection 299(1) of the ETA.
In the recent decision of Truong v. Canada, 2018 FCA 6 (“Truong”), the Federal Court of Canada (“FCA”) confirmed that alternative assessment methodologies are permissible when the CRA is unable to audit a taxpayer using the traditional method.
