Questão jurídica principal
Whether the estimated tax assessment was obviously incorrect and had to be replaced by an ordinary assessment.
Decisão extraída
No. The taxpayers did not substantiate their objection with adequate records or evidence; the assessment by estimation therefore stood.
Fundamentação extraída
In an appeal against an estimated assessment, the taxpayer must prove within the objection period that the estimate is obviously wrong. Mere explanations about falling margins or general assertions of arbitrariness are insufficient without a continuous cash book and supporting receipts.
