Key legal question
Whether the tax authorities and the cantonal court correctly refused to reopen an estimated assessment despite the late filing of incomplete income information.
Extracted holding
A challenge to an estimated assessment must set out the facts and offer the necessary evidence; a partial or blanket objection is insufficient. Because the taxpayers still did not file a complete tax return and did not establish the overall tax base, the non-entry decision was lawful.
Extracted reasoning
Under Art. 48(2) StHG and the corresponding cantonal rules, objection to an estimated assessment is admissible only if the assessment is shown to be manifestly incorrect. The omitted cooperation must be cured in the objection; otherwise the authority may not enter into the matter.
