STT Increase in F&O: What Every Trader Must Know Before April 1, 2026

Securities Transaction Tax (STT) on Futures & Options (F&O) is set to rise sharply from April 1, 2026. Announced in Union Budget 2026-27 by Finance Minister Nirmala Sitharaman, this hike directly impacts every derivatives trader in India and marks the government's strongest fiscal intervention yet to curb excessive speculation in the derivatives market.

What Is STT?

Securities Transaction Tax is a direct tax levied by the Government of India on transactions involving securities listed on recognised stock exchanges such as NSE and BSE. Introduced under the Finance (No. 2) Act, 2004, STT is collected at the point of transaction by the exchange — regardless of whether the trade is profitable or not.

The New STT Rates Effective April 1, 2026

The Budget 2026-27 announced the following revised rates exclusively for the derivatives segment. STT on the sale of futures rises from 0.02% to 0.05% of contract value — a 150% increase. STT on the sale of options premium rises from 0.10% to 0.15% — a 50% increase. STT on exercised options rises from 0.125% to 0.15%. STT on equity delivery and intraday cash market trades remains completely unchanged. The hike targets derivatives alone.

Why Did the Government Do This?

The hike is backed by hard data. SEBI's study on profit and loss of individual traders in the equity F&O segment found that 9 out of 10 individual traders incurred net losses. SEBI data further revealed that individual traders collectively lost over Rs. 1.06 lakh crore in F&O in FY2025-26 alone. Despite prior regulatory measures introduced by SEBI in late 2024 — including upfront option premium collection and stricter exposure limits — F&O volumes continued climbing. The STT hike is the government's stronger fiscal tool to cool what Revenue Secretary Arvind Shrivastava described as transactions "largely in the realm of heavy speculation."

Real Impact on Your Trades

The numbers are straightforward. A trader selling Nifty Futures with a contract value of Rs. 13 lakh paid approximately Rs. 260 in STT per sell trade at the old rate. From April 1, 2026, the same trade attracts Rs. 650 — an increase of Rs. 390 per lot. For options traders selling Rs. 1,00,000 worth of premium, STT moves from Rs. 100 to Rs. 150 per trade. For high-frequency traders and scalpers operating on razor-thin margins, this cost escalation makes several previously profitable strategies unviable.

Can You Claim STT as a Tax Deduction?

Yes — but only if you correctly treat F&O income as business income under the Income Tax Act, 1961, as prescribed by the Central Board of Direct Taxes (CBDT). In that case, STT paid is an allowable business expenditure and can be deducted while computing taxable profits. This makes maintaining proper books of accounts and filing ITR-3 more important than ever for active traders.

The Bigger Picture

From a revenue standpoint, STT collections up to March 17 in FY2026 already stood at Rs. 55,717 crore — surpassing the entire FY2025 collection of Rs. 53,095 crore, according to provisional data from the Income Tax Department. The hike will further strengthen this revenue stream while simultaneously discouraging speculative retail participation. The policy direction from both the government and SEBI is consistent: India's derivatives market is maturing, and sustainable, informed participation is the expectation going forward.
