Questione giuridica chiave
Whether the tax office was entitled to refuse entry on the objection against the estimated assessment
Decisione estratta
No. The taxpayers had substantiated why they could not yet file a complete return; the absence of a full tax return was not itself a procedural admissibility requirement.
Motivazione estratta
For an estimated assessment, the objection must be reasoned and evidence must be named, but the filing of a complete return is not a separate process prerequisite. In special situations, sufficiently substantiated explanations may suffice even if the return cannot yet be completed.
