If you trade futures and options actively, April 1, 2026 brings a cost increase that will show up in every single trade you make from that date onwards. The government is raising Securities Transaction Tax on derivatives, and while the percentage change looks small on paper, the actual rupee impact on active traders adds up to a meaningful increase in annual trading costs that every F&O participant needs to factor into their strategy.
Here is exactly what is changing, what it means in rupees, and what you should do about it.
What Is STT and Why It Matters for F&O Traders
Securities Transaction Tax is a tax levied on the value of securities transactions executed on recognised stock exchanges. Unlike brokerage or exchange charges, STT goes directly to the government and is non-negotiable. You cannot shop around for a lower STT rate the way you can negotiate brokerage. Every F&O trade you execute on NSE or BSE after April 1 will attract the new, higher STT rates automatically.
STT is deducted at source by your broker on your behalf and remitted to the government. It shows up on your contract note for every trade. For casual traders it may seem like a rounding line item. For active intraday and positional F&O traders who execute dozens of trades per day, it is a material cost that directly affects profitability.
The New STT Rates From April 1, 2026
Futures STT is increasing from 0.02 percent to 0.05 percent on the turnover value. This is a 150 percent increase in the futures STT rate. Options STT on premium is increasing from 0.1 percent to 0.15 percent. Options STT on exercise is increasing from 0.125 percent to 0.15 percent. All changes take effect from April 1, 2026.
What This Means in Actual Rupees
The impact calculation depends on your trading style and volumes. Here are concrete examples that make the numbers real.
For a futures trader executing one lot of Nifty 50 futures where the contract value is approximately ₹11 lakh at current index levels. Under the old STT rate of 0.02 percent, the STT per trade was approximately ₹220. Under the new 0.05 percent rate, the STT per trade is approximately ₹550. Each Nifty futures trade costs ₹330 more in STT from April 1.
A trader who executes 10 Nifty futures round trips per day pays ₹6,600 more in STT per day under the new rate. Over 20 trading days in a month that is ₹1,32,000 in additional STT per month. Over a trading year of approximately 240 sessions that is approximately ₹15,84,000 in additional annual STT for a trader doing 10 Nifty futures round trips per day.
For an options trader, the increase is comparatively more moderate in absolute terms because the STT on options is calculated on the premium value rather than the notional contract value. An options trade with a total premium of ₹5,000 attracted STT of ₹5 at the 0.1 percent rate. Under the new 0.15 percent rate, the same trade attracts ₹7.50. The increase per trade is small in absolute terms but accumulates for high-frequency options traders who execute dozens of trades daily.
The exercise STT increase is particularly relevant for options buyers who let their in-the-money options get exercised at expiry. The rate going from 0.125 percent to 0.15 percent on the notional value at exercise means that physically exercised options become marginally more expensive. Most retail traders close positions before expiry to avoid this, but those who do let options exercise will see a slightly higher STT on the exercise.
Why the Government Is Raising STT on F&O
The context for this increase is important. The Securities and Exchange Board of India and the government have expressed consistent concern about the scale of retail participation in F&O trading and the aggregate losses that retail traders are incurring. SEBI’s own study data showed that a large majority of individual F&O traders lose money in these instruments over time, with aggregate retail F&O losses running to tens of thousands of crores annually.
The STT increase is one of several measures, alongside SEBI’s lot size increases and contract expiry rationalisation, aimed at making speculative short-term F&O trading marginally less attractive and slightly more expensive, with the stated policy goal of encouraging retail investors toward less speculative instruments. Whether this goal is achieved through STT increases alone is debatable among market participants, but the revenue and policy intent is clear.
The government also collects meaningful revenue from STT given the extraordinary volumes in Indian F&O markets, which are among the highest in the world by number of contracts traded. The rate increase provides additional government revenue from a market segment that has grown explosively over the past five years.
Who Is Most Affected
High-frequency intraday traders who execute multiple futures round trips daily face the largest absolute increase in STT costs. The 150 percent increase in futures STT rate translates directly into a proportional increase in their daily STT bill. For these traders, whose profitability often depends on executing strategies with very thin per-trade margins, the higher STT meaningfully reduces the strategy’s profitability or viability.
Positional futures traders who hold contracts for days or weeks face a smaller number of transactions but the same rate increase applies to each. The impact is less acute per day but still accumulates over months of trading.
Options sellers who trade high premium contracts and execute significant volume will see a meaningful increase in their STT outgo. Options buyers who trade lower premium instruments will see a smaller absolute increase but the proportional impact on their per-trade cost structure is the same 50 percent rate hike.
Hedgers who use futures and options to hedge underlying equity or portfolio positions will see their hedging costs increase, making hedging strategies marginally more expensive. For institutional hedgers this is a manageable cost adjustment. For retail traders using F&O to hedge equity positions, the cost of hedging rises.
What Should Active F&O Traders Do
The first and most immediate action is to recalculate your trading cost structure to reflect the new STT rates. Every strategy you currently employ with a positive expected value should be stress-tested against the higher STT to confirm it remains profitable after the increase. Strategies that were marginally profitable at the old STT rate may no longer be viable from April 1.
The second consideration is trade frequency. If your current approach involves many small trades, the STT increase makes each trade relatively more expensive. Consolidating into fewer, larger positions where the strategy allows reduces the cumulative STT burden.
The third consideration is instrument selection within your strategy. For some trading approaches, shifting emphasis between futures and options, or between different expiry series, may partially mitigate the STT impact depending on the specific rate structure that applies to each.
The broader takeaway for all F&O participants is that the regulatory and tax environment for derivatives trading in India is becoming progressively less accommodating for high-frequency retail speculation. The combination of SEBI’s structural changes and the STT increase represents a sustained policy direction that active traders should incorporate into their long-term assessment of F&O as an income-generating activity.
From April 1, every F&O trade you make will cost more. The best preparation is to know exactly how much more before that date arrives.
