Key legal question
Whether the Solothurn tax office could order a bookkeeping audit after an inter-cantonal seat transfer
Extracted holding
Yes. After a seat transfer during the tax period, the former canton may conduct its own assessment proceedings and may order a tax audit as part of those proceedings.
Extracted reasoning
Art. 22 and 39 StHG allow both cantons to tax the period; the former canton retains procedural rights and may request business books and records under cantonal law.
