Kernrechtsfrage
Whether the taxpayer proved that the 2002 undeclared income from independent work was not taxable or was lower than assessed.
Extrahierter Entscheid
The taxpayer did not rebut the evidence indicating that he worked on a construction site and earned undeclared independent income; CHF 15,000 was upheld.
Extrahierte Begründung
The courts relied on a consistent set of objective indications, while the taxpayer gave contradictory and implausible explanations. In tax proceedings, once the authority has gathered sufficient indicia of undeclared taxable elements, the taxpayer must substantiate his contrary assertions.
