Key legal question
Whether the cantonal court correctly upheld the non-entry on the taxpayer's objection against the estimated tax assessment.
Extracted holding
Yes. The objection did not meet the statutory duty to provide a sufficiently substantiated challenge showing the assessment was manifestly incorrect.
Extracted reasoning
After a discretionary assessment, correction is possible only if the taxpayer substantiates that the assessment is plainly wrong. The taxpayer again relied on unsubstantiated calculations and incomplete documents, which was insufficient.
