Question juridique clé
Whether the taxpayer's income could be assessed by estimation under Art. 68 StG.
Solution extraite
Yes. Because no proper books were kept, a numeric assessment was impossible and estimation based on experience could be made, taking proven special circumstances into account.
Motifs extraits
The taxpayer had a turnover above CHF 50,000 and would have been subject to registration and bookkeeping duties. Without accounts, a precise assessment was impossible.
