Principal Issues: In the case of a voluntary disclosure made more than ten years after the taxation year to which the disclosure relates, whether the limitation period under subsection 222(4) begins at the time income is earned, where no assessment has been issued for the particular taxation year.
Position: No.
Reasons: The collection limitation period provided by subsection 222(4) is with respect to a "tax debt" payable by the taxpayer. Although without an assessment a taxpayer may be liable for tax according to subsection 152(3) of the Act, a tax liability only becomes payable when the tax payable is fixed with a notice of assessment according to the definition of tax payable provided by subsection 248(2). Where no assessment has been made, the tax is not yet tax payable and is not a "tax debt" subject to the limitation period provided by subsection 222(4). Therefore, the collection limitation period cannot begin to run without a notice of assessment.
