Questione giuridica chiave
Whether the factual findings on taxable turnover of CHF 102,800 and the resulting supplemental VAT assessment of CHF 5,345 were manifestly incorrect.
Decisione estratta
The taxpayer did not show manifest factual error or accounting proof sufficient to overturn the lower authority's findings.
Motivazione estratta
The Federal Court is bound by the facts found by the judicial authority unless they are manifestly inaccurate; the taxpayer's new turnover figure of CHF 69,090 was raised too late and was not supported by persuasive documents.
