Key legal question
Whether 90% commission transfers to the Liechtenstein company were deductible business expenses.
Extracted holding
The taxpayers failed to prove that the transfers corresponded to genuine services and were commercially justified; no deduction was allowed.
Extracted reasoning
For foreign payments, strict proof is required. The record lacked invoices and verifiable evidence of actual services. The structure allowed the taxpayer to shift activities at will, and the claimed work allocation was not substantiated.
