my client is doing software services to US client, so we have taken GST registration and we are filing NIL gst returns monthly. recently my client has received 3 lakhs through paypal and later he was transferred money to his bank account which is mentioned in GST Registration. upto this date we have file nil gst returns. now my doubt is 1. whether we need to pay gst @18% on 3 lakhs or not? 2. where to show this amount in gst return if gst not applicable?
