The Tax Court of Canada Cannot Increase An Assessment Above The Canada Revenue Agency's Assessment
When a taxpayer appeals an assessment to the Tax Court of Canada, the amount of the assessment can only go down; it cannot go up higher (with the exception of the added interest that accrues after the date of the assessment). In other words, if the Canada Revenue Agency (CRA) assessed $25,000, the Tax Court cannot undertake a calculation and determine the number should have been $30,000 and then increase the assessment. The decision of the Tax Court of Canada would have to be to confirm the CRA's $25,000 assessment.
We are reminded of this in Long Ha v. The Queen (I love the name of this case). Judge Miller refers to a decision of Judge Thurlow in Harris v The Minister of National Revenue [1964] C.T.C. 562 (Ex.Ct.):
On a taxpayer's appeal to the Court the matter for determination is basically whether the assessment is too high. This may depend on what deductions are allowable in computing income and what are not but as I see it the determination of these questions is involved only for the purpose of reaching a conclusion on the basic question. No appeal to this Court from the assessment is given by the statute to the Minister and since in the circumstances of this case the disallowance of the $775.02 while allowing $525 would result in an increase in the assessment the effect of referring the matter back to the Minister for that purpose would be to increase the assessment and thus in substance allow an appeal by him to this Court.
Whether the CRA may issue a second assessment for additional tax will depend on whether the amount at issue is statute-barred. Often a tax dispute takes more than 4 years to proceed through the objection and appeal process. The CRA will not be entitled to issue a second assessment unless (1) the limitation period for the assessment has not expired or (2) the error is a misrepresentation attributable to neglect carelessness or willful default or fraud or (3) the taxpayer signed a waiver relating to the period at issue and has not revoked the waiver.
