Securities Transaction Tax (STT) Structure

Securities Transaction Tax is a small levy on the value of trades in listed securities, charged at different rates for delivery, intraday, futures and options.

STT is collected at the time of transacting in listed shares and derivatives on recognised exchanges, with separate rates for delivery-based equity, intraday trades, futures and options, and on which side of the trade it applies. Because it is collected at source by the exchange, it is hard to evade.

Beyond raising revenue, STT historically tied into how gains were taxed, since concessional capital-gains treatment was linked to STT having been paid. For active traders, STT is a meaningful transaction cost, and changes to its rates in the Budget directly affect derivative-market economics.
