Introduced in 2004, Securities Transaction Tax is a direct tax levied on transactions involving securities (equity shares, options, futures) traded on recognised stock exchanges in India or redemption of equity oriented mutual fund units.
STT is collected by stock exchanges/Mutual Fund at the time of transaction and remitted to the government. Investors do not need to make separate payments or file declarations for STT. The amount is clearly shown in contract notes, broker statements or statement of accounts of Mutual Fund.
Unlike capital gains tax, which applies only when an investor earns a profit, STT applies to every eligible transaction regardless of its profitability. Whether a trade results in a gain or a loss, STT is charged as long as the transaction falls within its scope.
