Question juridique clé
Whether the tax authority could rely on estimated assessment for self-employed income
Solution extraite
Yes. The submitted records lacked the evidentiary value required, so estimation was permitted.
Motifs extraits
For cash-intensive businesses, a cash book must be kept timely, complete and traceable. The taxpayers submitted only loose cash and bank vouchers and a list of income and expenses, not a proper cash book; therefore the authority could reject the books and assess ex officio.
