STT on F&O After Budget 2026: Real Cost Impact for Indian Traders
In short: From 1 October 2024, Securities Transaction Tax (STT) on F&O trading was hiked sharply. Sell-side STT on equity options jumped from 0.0625% to 0.1% of premium (a 60% increase). Sell-side STT on equity futures rose from 0.0125% to 0.02% of trade value (also 60% increase). Buying options attracts no STT (only exercised options do). For every ₹1 crore of options premium sold, the 2024 hike added ₹3,750 of STT; at ₹10-50 crore of turnover, the hit was ₹37,500 – ₹1.9 lakh a year. Budget 2026 then raised STT again from 1 April 2026: futures to 0.05% and options premium to 0.15% — futures STT is now 4× its pre-October-2024 level. STT is fully deductible as a business expense under Section 36(1)(xv) for traders filing F&O as non-speculative business income — so the net-of-tax cost is roughly 70% of the gross hike for 30%-slab traders. Strategically, the hike has compressed margins on premium-selling, scalping, and arbitrage strategies; some retail traders have shifted to longer-dated positions to reduce turnover.
Update: Budget 2026 raised STT again (from 1 April 2026)
| Transaction | Before 1 Oct 2024 | 1 Oct 2024 – 31 Mar 2026 | From 1 Apr 2026 |
|---|---|---|---|
| Futures (sell side, on trade value) | 0.0125% | 0.02% | 0.05% |
| Options premium (sell side) | 0.0625% | 0.1% | 0.15% |
| Options exercised (on intrinsic value) | — | 0.125% | 0.15% |
Futures STT is now 4× its pre-October-2024 level (0.0125% → 0.05%). Equity delivery and intraday cash-market STT were not changed.
Worked examples at 2026 rates
- ₹1 crore of options premium sold: STT ₹6,250 (pre-Oct 2024) → ₹10,000 (Oct 2024) → ₹15,000 (now)
- ₹1 crore of futures sold: STT ₹1,250 → ₹2,000 → ₹5,000 (now)
The trader profiles below show the October 2024 change, with the current (April 2026) annual STT added for each.
The October 2024 STT Rates
| Instrument | Side | Pre-1 Oct 2024 | Post-1 Oct 2024 | Increase |
|---|---|---|---|---|
| Equity options | Sell (on premium) | 0.0625% | 0.1% | +60% |
| Equity options | Buy (on premium) | Nil | Nil | Unchanged (STT only on exercise) |
| Equity futures | Sell (on trade value) | 0.0125% | 0.02% | +60% |
| Equity futures | Buy | Nil | Nil | Unchanged |
| Equity delivery (cash market) | Both | 0.1% | 0.1% | Unchanged |
| Intraday equity (cash market) | Sell only | 0.025% | 0.025% | Unchanged |
The increase is entirely on the F&O sell-side. The Finance Ministry rationale: F&O has seen explosive retail participation since 2020 (from ~4 lakh active traders to over 1.5 crore by 2023 per SEBI data), with SEBI studies showing 90%+ of retail F&O traders lose money. The STT hike aims to reduce speculative volume without harming retail cash-market investors.
Real Cost Impact Across Trader Profiles
Casual Options Trader
Trades 5-10 options lots per month, monthly turnover ₹5 lakh in premium.
Annual sell-side options turnover: ₹60 lakh.
Old STT: ₹60 lakh × 0.0625% = ₹3,750/year
New STT: ₹60 lakh × 0.1% = ₹6,000/year
Annual increase: ₹2,250. Net-of-tax (after 30% slab business deduction): ₹1,575 actual increase. Not life-changing but felt. At April 2026 rates: ₹9,000/year.
Active Retail Options Trader
Daily-active trader, monthly premium turnover ₹50 lakh, fairly balanced strategies.
Annual sell-side options turnover: ₹6 crore.
Old STT: ₹6 crore × 0.0625% = ₹37,500/year
New STT: ₹6 crore × 0.1% = ₹60,000/year
Annual increase: ₹22,500. Net-of-tax: ~₹15,750 actual. For a trader making ₹2-5 lakh annual profit, this is 5-10% of bottom line — material. At April 2026 rates: ₹90,000/year.
Premium-Selling Specialist
Delta-neutral or short-strangle trader. Monthly premium turnover ₹2 crore.
Annual sell-side turnover: ₹24 crore.
Old STT: ₹24 crore × 0.0625% = ₹1.5 lakh/year
New STT: ₹24 crore × 0.1% = ₹2.4 lakh/year
Annual increase: ₹90,000. Net-of-tax: ₹63,000. For premium-sellers with annual expected returns around 8-12% on capital, this knocks 0.5-1 percentage point off net annualised returns. At April 2026 rates: ₹3.6 lakh/year.
Futures Trader
Active futures trader, monthly futures notional turnover ₹5 crore (typical for moderate intraday or swing trader).
Annual sell-side futures turnover: ₹60 crore.
Old STT: ₹60 crore × 0.0125% = ₹75,000/year
New STT: ₹60 crore × 0.02% = ₹1.2 lakh/year
Annual increase: ₹45,000. Net-of-tax: ~₹31,500. At April 2026 rates: ₹3 lakh/year — 2.5× the October 2024 level.
High-Frequency Algo / Prop Trader
Algo trader running prop strategies, monthly options premium turnover ₹20 crore.
Annual sell-side options turnover: ₹240 crore.
Old STT: ₹240 crore × 0.0625% = ₹15 lakh/year
New STT: ₹240 crore × 0.1% = ₹24 lakh/year
Annual increase: ₹9 lakh. Net-of-tax: ~₹6.3 lakh actual. For HFT firms, this materially impacts strategy economics — many previously profitable scalping strategies became marginal or unprofitable after October 2024. At April 2026 rates: ₹36 lakh/year.
Tax Deductibility — Section 36(1)(xv)
For traders filing F&O income as Non-Speculative Business Income in ITR-3, STT is an allowable expense under Section 36(1)(xv) of the Income Tax Act. The increased STT reduces taxable business income proportionately. After-tax cost calculation:
For a 30%-slab trader: actual after-tax cost of STT hike = Gross hike × (1 – 0.30) = 70% of gross hike.
For 20% slab: 80% of gross hike.
For 5% slab: 95% of gross hike.
Note: the Income-tax Act, 2025 applies from 1 April 2026 and these provisions have been renumbered; the deduction for STT paid on business transactions continues. Returns for FY 2025-26 still use the old section numbers.
For traders incorrectly classifying F&O as capital gains (rare and against settled tax position), STT is not deductible — the full hike falls on you.
A note on intraday equity (which is speculative business income): STT on intraday is similarly deductible against speculative business income, but speculative losses can only set off against speculative gains — different from F&O. See our F&O and intraday tax guide for the full set-off rules.
Impact on Specific Trading Strategies
Premium Selling (Iron Condor, Short Strangle)
Strategies that rely on selling far-out-of-money options. The 60% STT hike on sell-side options premium translated to roughly 0.04 percentage points additional cost per trade (and another 0.05 points from April 2026) — meaningful for strategies that aim for 1-2% per trade return. Annualised drag: 5-15% of strategy returns for tight-margin variants.
Mitigation: Trade larger sizes less frequently. Move from weekly to monthly expiries (reduces turnover per unit of return). Be more selective on strikes (sell deeper OTM less often).
Scalping
High-frequency in-and-out positions. Death by a thousand cuts: each round-trip incurs STT of 0.1% of premium on the sell leg (0.15% from April 2026); the buy leg carries no STT. For a scalp targeting 1-2% per trade, STT alone eats 7-15% of gross profit.
Mitigation: Often unviable post-hike. Many scalping strategies have been retired by retail traders. Algorithmic scalpers in HFT firms have rationalised, focusing on higher-edge setups.
Calendar Spreads / Vertical Spreads
Less affected since these involve both buy and sell legs (one leg on each side). Buy legs carry no STT; only the sell legs are taxed. Net impact is roughly half what naked option sellers see.
Long Options (Buy and Hold)
Least affected. Buying options attracts no STT. Long call/put strategies see no STT at entry; only the eventual square-off triggers sell-side STT (0.1%, now 0.15%), or 0.15% of intrinsic value if the option is exercised.
Futures Arbitrage / Cash-Futures Basis Trading
Affected on the futures sell leg. Cash market STT is unchanged. Arbitrage spreads compressed by about 0.75 basis points per cycle in 2024 and a further 3 basis points from April 2026 — significant for arbitrage targets of 5-15 basis points per cycle.
Broker and Exchange Charges — Compare After STT
STT is government-imposed and equal across all brokers. But brokerage, exchange charges, and SEBI fees vary. Total per-lot costs (for a typical Nifty 50 options lot of ₹50,000 premium):
| Cost component | Sell side (April 2026 rates) |
|---|---|
| STT (0.15%) | ₹75 |
| Exchange transaction charge (~0.0035% on options premium NSE) | ₹1.75 |
| SEBI fee (0.0001% on turnover) | ₹0.05 |
| GST on brokerage + exchange + SEBI (18%) | ~₹4-9 |
| Brokerage (₹20 max at Zerodha, Dhan, Upstox; varies elsewhere) | ₹20 |
| Total sell-side cost | ₹100-110 per ₹50K premium lot |
STT is now the single largest non-brokerage cost component. Switching brokers helps only on brokerage (₹5-20 difference per trade); STT is identical everywhere.
Wider Context: Why Government Is Targeting F&O
SEBI’s January 2023 study of 45 lakh retail F&O traders revealed that 89% lost money, with average annual loss of ₹1.1 lakh per losing trader. The aggregate annual retail F&O loss was estimated at ₹50,000+ crore. This raised concerns at the regulator and Ministry of Finance. SEBI’s study found 91% of individual F&O traders made net losses in FY25 (average loss ~₹1.1 lakh). Its latest study shows the loss rate rises to 95%+ among traders active for 4+ years.
The STT hike is part of a broader policy bundle aimed at moderating retail F&O speculation:
- Lot size increases — SEBI doubled minimum lot sizes for many index options (effective late 2024), raising the per-contract capital requirement and effectively pricing out smaller retail accounts.
- Weekly expiry restructuring — SEBI reduced weekly expiries per exchange (initially capping at 1 per exchange per week), eliminating the daily “expiry trading” frenzy that had developed.
- STT hikes (October 2024 and April 2026) — the focus of this article.
- Tighter margin requirements — staggered increases in upfront margin for short-options positions.
Early data from Q4 2024 and Q1 2025 shows retail F&O participation has declined 10-20% from peak levels, suggesting the policy bundle is having its intended effect. Volume on weekly expiries dropped sharply.
Strategies to Offset the Hike
- Trade longer expiries. Move from weekly to monthly (or further). Same directional view, lower turnover, less STT per unit of return.
- Increase trade size, decrease frequency. If your strategy has 60% win rate at ₹5,000 profit per trade, trading 5 times per week generates ₹15,000 net of STT/costs at old rates. Trading 2 times per week at ₹12,500 expected profit per trade (larger size) generates ₹16,000 net — same hit rate, lower transaction tax drag.
- Switch to spreads instead of naked selling. Vertical spreads, iron condors with defined risk reduce the proportion of premium-paid relative to gross volume.
- Track and deduct STT diligently. Many casual traders forget to deduct STT, brokerage, and other costs at ITR filing — losing the tax shield. Use broker P&L statements with cost breakup for accurate filing.
- Re-evaluate strategy expected value (EV). Many strategies pre-hike had EV of +₹200 per round trip after costs. Post-hike, those strategies may have EV of +₹80-100. The threshold for “is this worth trading” has moved up.
Frequently Asked Questions
Will STT be reduced back if F&O volumes drop sharply?
Unlikely — Budget 2026 raised it again from 1 April 2026. Government revenue from STT exceeds ₹30,000 crore annually. The political and fiscal incentive to maintain elevated rates is strong. STT hikes are sticky.
Do these STT rates apply to currency futures and options?
Currency F&O has its own STT regime (CTT for commodities). The equity F&O hike does not directly apply. Currency F&O STT rates were not changed in October 2024.
Does STT apply to options that expire worthless?
Sell-side STT is charged at the time of selling (writing) the option. If the option expires worthless, no further STT — the writer keeps the premium minus the initial STT collected. For the option buyer who lets it expire worthless: STT was paid at entry; no additional STT at expiry.
What about options that get exercised (physical settlement)?
SEBI mandated physical settlement on stock options from FY 2019-20. On exercise: STT applies at 0.125% of intrinsic value (0.15% from April 2026) on the exercised contract, and the writer has already paid sell-side STT on the premium. Net effect: physical settlement of options is more STT-expensive than letting them expire worthless or squaring off pre-expiry.
Are there any STT-free alternatives to F&O?
Equity delivery STT is unchanged. Direct equity trading (cash market) has no equivalent of F&O STT spike. For directional bets, holding equity for 1+ year and paying 12.5% LTCG can be more efficient than rolling weekly options for the same directional view.
Does STT show up on my contract note?
Yes — every trade contract note from your broker shows the exact STT amount. At ITR time, sum these up from your annual P&L statement (Zerodha Console, Groww annual statement, etc.) for the business expense deduction.
I am a salaried employee dabbling in F&O. Do I file ITR-3?
Yes — F&O income (profit or loss) goes in ITR-3 under business income head, regardless of your day job. The salary remains under salary head. Both incomes are taxed together at slab rates. Filing ITR-3 is mandatory once you have any F&O activity.
