Questione giuridica chiave
Whether the 250,000 CHF settlement payment was deductible as professional expense under direct federal tax law
Decisione estratta
No deduction was allowed because the taxpayers failed to produce requested documents, so the authorities could not establish the required causal link to professional activity.
Motivazione estratta
For such complex deduction claims, the tax authorities may request relevant documents. The taxpayers breached their duty to cooperate and cannot benefit from that failure; the authorities could therefore deny the deduction without deciding whether the underlying conduct was gravely negligent.
