Questão jurídica principal
Whether WIR payments to third parties were deductible business expenses for the taxpayer's self-employment income
Decisão extraída
No. The taxpayer did not prove that the third-party payments were commercially justified or linked to his business; the invoices were unrelated to him and the bookings were inaccurate.
Fundamentação extraída
The WIR receipt of CHF 100,996 was undisputed, but the corresponding invoices referred to another debtor and had no concrete connection to the taxpayer's printing business. The taxpayer bore the burden of proving a tax-reducing fact and failed to do so.
