Key legal question
Which value must be deducted when computing the taxable capital gain on sale of business property: book value or alleged acquisition value?
Extracted holding
The taxpayer had to be bound by the 500,000 CHF book value recorded in the business accounts; the gain is computed on that basis.
Extracted reasoning
The accounting entry was not a manifestly unlawful valuation error. Under the principle of consistency with commercial accounts, a businessman who keeps proper books must accept the chosen book values unless the entry clearly violates mandatory accounting law. No basis existed to depart from the recorded value.
