The GST and Payment Gateway fees are additional charges that apply to certain MStock plans. These fees are not part of the brokerage structure but are mandatory as per regulatory requirements and payment methods. The exact GST rate typically depends on the brokerage charges, which is around 18% on the brokerage fee, and the Payment Gateway fee may vary based on the payment method selected (like UPI, debit/credit card, etc.). These fees apply on top of your brokerage charges and are calculated at the time of the transaction. It’s important to review the specific fees for your chosen plan to ensure you’re aware of any additional costs.
