Stock brokers must pay SEBI transaction fees across market segments; turnover based rates and annual registration charges apply. Regulation 41 requires stock brokers, clearing members and self clearing members to pay segment specific fees to the Board for securities transactions, with turnover based rates for cash, derivatives, commodity, debt and electronic gold receipt segments. 'Turnover' includes executed trades and trades settled on contract expiration; options turnover is computed on premium and additionally on notional value when exercised or assigned. Clearing members/self clearing members must pay an annual non refundable fee of Rs.50,000 while registration is in force (first year with application, subsequent years before 1 June), and the registration application fee is Rs.50,000, payable by direct credit via SEBI payment gateway.
