In their post-trial briefs, petitioners argue that respondent's determination that petitioner received unreported income from H&B "is inherently arbitrary and excessive on its face". Petitioners argue that respondent's determination is therefore not entitled to the presumption of correctness, and respondent bears the burden of proving "that the petitioners had unreported income." Generally, a taxpayer bears the burden of proving that the Commissioner's determination of a deficiency is erroneous. See Rule 142(a). All Rule references are to the Tax Court Rules of Practice and Procedure. However, in a case such as this, in which the Commissioner determines that a taxpayer realized unreported income, the Commissioner must provide a minimal evidentiary foundation for the deficiency determination before the presumption of correctness attaches to it.
