Kernrechtsfrage
Whether the taxpayer's records were sufficient to preclude an office assessment of business income.
Extrahierter Entscheid
No. The daily tables, compared with tachograph data, did not provide sufficiently probative and complete data; a proper cash book was also missing.
Extrahierte Begründung
The mileage and revenue gap remained unexplained; the claimed flat-rate fares and empty runs were not plausibly evidenced. Under the applicable rules, insufficient probative data required taxation by estimate.
