My total PSX portfolio is around Rs.7.1 million. I transferred a fresh Rs.60,000 from my bank account to Eagle Services to reinvest in PSX. Only Rs.14,000 was credited/available, while Rs.46,000 was deducted from my cash balance. When I contacted the brokerage helpline, they said it was Capital Gains Tax (CGT) deducted from my cash. Can someone explain why Rs.46,000 is being deducted and how CGT is calculated?
