STT Hike on Futures and Options: New Rates Effective April 1, 2026

The Union Budget 2026 introduced a significant increase in Securities Transaction Tax rates on futures and options contracts, effective from April 1, 2026. STT on the sale of futures contracts has been raised from 0.02 percent to 0.05 percent, a 150 percent increase. On the sale of options, the rate on premium has been raised from 0.10 percent to 0.15 percent, while the rate on exercise of options has moved from 0.125 percent to 0.15 percent. These increases apply to all derivatives transactions executed on recognised stock exchanges from the effective date.

The Rate Changes in Detail

The STT increase covers three categories of derivative transactions. For futures, the seller pays STT at 0.05 percent of the transaction value, up from 0.02 percent. To illustrate the impact: on a Nifty futures contract with a notional value of approximately Rs 16 lakh, the STT obligation rises from around Rs 322 to approximately Rs 806 per lot, an additional cost of roughly Rs 484 per lot. For options sold (on premium), the seller pays STT at 0.15 percent of the premium amount, up from 0.10 percent. For options exercised, the buyer pays STT at 0.15 percent of the settlement price, up from 0.125 percent. The rate on delivery-based equity transactions remains unchanged at 0.10 percent on both purchase and sale.

Policy Rationale: Curbing Retail Speculation

The STT hike follows a series of measures by regulators and the government aimed at curbing excessive retail participation in derivatives markets. SEBI had previously flagged that over 90 percent of individual traders in the futures and options segment incur net losses. The regulator had already tightened lot sizes and margin requirements in 2024. The government's decision to raise STT is a fiscal tool directed at the same objective: making speculative trading more expensive and thereby discouraging uninformed retail participation. The revenue impact is also significant, as derivatives volumes on Indian exchanges are among the highest globally, and even modest rate increases translate into substantial tax collections.

Impact on Market Participants

The increased STT directly raises the breakeven cost for every derivative trade. High-frequency traders and scalpers, who execute large numbers of trades with thin margins, will see their profitability compressed. Retail traders, particularly those trading intraday options strategies, face a meaningful increase in per-trade costs that may render certain low-premium strategies unviable. Institutional participants with larger position sizes will absorb the cost more easily but will still factor it into their overall transaction cost models. Brokers may see a reduction in derivative trading volumes if the higher STT deters marginal participants, which could affect brokerage revenue. Options writers, who collect premiums as income, face higher STT on their premium receipts.

Practical Takeaways

Traders and portfolio managers should recalculate their breakeven costs and adjust their trading strategies to account for the higher STT burden. Brokers and trading platforms should update their cost calculators and margin disclosures to reflect the new rates from April 1, 2026. Tax advisors should note that STT paid on futures and options is not deductible as an expense under the Income Tax Act where income from such transactions is treated as speculative income; however, where classified as business income, STT forms part of the cost of acquisition. Compliance teams at brokerages should verify that their systems are correctly applying the revised STT rates on all post-April 1 transactions.
