Prohibition on cash acceptance of loans or deposits requires bank instruments; contravention attracts penalty equal to the amount. Prohibition requires receipt of loans, deposits or specified sums by account payee cheque, bank draft or electronic clearing where the amount or aggregate meets the threshold, subject to specified institutional exceptions; a higher threshold applies to certain primary agricultural cooperative receipts. Contravention attracts a penalty equal to the amount taken, though the person may avoid penalty by proving reasonable cause; penalty imposition authority shifts to the assessing officer from the stipulated future date.
