Best Demat for F&O Trading in India (2026)

Futures and options is the segment where India's retail market concentrates — and where the government spent 2026 repricing participation. Brokerage is flat ₹20 per order at every major discount broker; the STT on futures doubled to 0.05%; options STT rose to 0.15%. When the statutory stack dwarfs the broker's fee, "best demat" means the platform, the settlement machinery and the margin plumbing — not the rate card. The verified picture, November 2026:

The flat-₹20 consensus

Zerodha: futures at 0.03% or ₹20 whichever is lower, options flat ₹20. Upstox: futures 0.05% or ₹20 whichever lower, options flat ₹20. Angel One: ₹20 per executed order across F&O — charged on expired, exercised and assigned contracts too. Dhan: ₹20 per order, same expiry/exercise rule, plus 0.10% of contract value on derivatives resulting in physical delivery. Groww: ₹20 per executed transaction. Sources: the brokers' own pricing pages, November 2026. Five brokers, one number. The comparison that remains is structural: margin, settlement, platform and API.

The 2026 STT reset, on the record

The Budget speech is explicit: STT on futures raised to 0.05% from 0.02%, and on options premium and exercise to 0.15% each, from 0.1% and 0.125% — framed as a "reasonable course correction in F&O segment". Source: Union Budget 2026-27 Finance Bill document, pib.gov.in, February 2026; Upstox's charges table dates the effective date as April 1, 2026. For a futures trader, 0.05% on a ₹10 lakh futures sell is ₹500 — twenty-five times the ₹20 brokerage. The tax line, not the broker line, is now the marginal cost of every F&O trade.

Physical settlement: the demat account's starring role

Stock futures and in-the-money stock options settle physically — shares actually move through demat accounts on expiry. Three charge lines attach: Dhan's 0.10% of contract value brokerage on physical-delivery derivatives; the ₹20 expiry/exercise event fees at Dhan and Angel One; and the standard DP debit charges if shares land and are later sold (₹15.34 per ISIN at Zerodha, ₹20 at Upstox, ₹3.5-plus-₹16.5 at Groww — per the schedules our demat-charges guide tabulates). A futures trader who never intends delivery still needs the demat account healthy, because the exchange's settlement system does not ask for intentions.

Margin plumbing: pledges, peaks and premiums

F&O selling is margin-funded, and the plumbing is standardised with broker-level pricing on top. Pledging demat holdings as margin: ₹20–30 plus GST per ISIN per request across the compared brokers (Upstox: ₹20 plus GST per scrip). Peak margin: SEBI's framework (circular of July 20, 2020, collected at 100% since the phase-in per the master circular's risk chapter) snapshots margins through the day and penalises the higher of end-of-day and peak shortfalls — the leverage ceiling that ended the old high-leverage intraday products. Option buying: no margin, full premium, no leverage — Upstox's schedule states it in one line. And the 2026 STT increase applies to every futures sell and every premium sold, which is why position-sizing against the statutory stack is now the first skill, as the Budget's own rationale implies.

API and algo access: the 2025 framework in production

Serious F&O traders automate — spreads, hedges, expiry management. The legal path is SEBI's retail algo framework (circular of February 4, 2025, fully in force from April 1, 2026): a personal API key, orders from a broker-whitelisted static IP, and an exchange-issued Algo-ID stamped on every automated order, with the broker accountable for each algo it allows — the structure our demat-algo guide verifies in detail. If automation is your plan, the broker comparison narrows to API rate limits, order-type coverage and the stability of the static-IP flow — a different shortlist than the fee table suggests, and worth deciding before the strategy, not after.

Rollovers and the expiry calendar

Futures live in three-month series, so a continuing position rolls: close the expiring contract, open the next series, pay the ₹20-class brokerage on both legs plus the basis spread between them. The rollover calendar concentrates in expiry week — when the whole market rolls, liquidity in the new series is thinnest at exactly the times you want it — and a sloppy roll can cost more than a month of brokerage. Write the rollover into the position's plan at entry: which week, which session, and the maximum acceptable spread. Options writers run the same calendar monthly, with the 0.15% STT now attached to every premium they sell.

Selling options on pledged collateral, worked

The standard retail setup for option writing without fresh capital: pledge the equity portfolio, receive collateral after the exchange haircut on each stock, and post SPAN-plus-exposure margins against short options. On a ₹5 lakh portfolio, haircuts leave roughly ₹3.5–4 lakh of usable collateral — the haircut percentage is stock-specific and published by the exchanges, so verify it for your actual holdings rather than assuming. The costs: pledge and unpledge fees of ₹20–30 plus GST per ISIN, any interest the broker charges on the pledged line, and the peak-margin snapshots policing the position through the day. What the structure buys: the long-term portfolio stays invested while its value works as margin — the closest thing F&O has to a free lunch, provided the trading is disciplined enough not to threaten the collateral.

The tax file: F&O is business income

F&O profits and losses are business income for tax purposes — filed in ITR-3 with a P&L, not in the capital-gains schedules — and the record-keeping follows: every contract note, the trading ledger, the bank statements, and the STT actually paid (which the new 0.05% and 0.15% rates make a material P&L line). Losses carry forward only on a timely filed return, and the turnover computation for audit purposes follows the derivatives definition the department applies. Our ITR guide covers the calendar — August 31 for non-audit business filers for AY 2026-27, November 21 for audit cases — and our freelancer guide the books-versus-presumptive question: F&O traders do not fit presumptive comfortably, so the books habit starts with the first contract note.

The side-by-side

Currency and commodity F&O: the quiet corners

The F&O mandate covers more than equity. Currency futures and options trade with the same ₹20-class brokerage and — per Zerodha's schedule — no STT at all, which makes them the statutory-cheapest derivatives segment for traders hedging travel or trade payables alongside speculation. Commodity futures on the MCX carry 0.01% CTT on the sell side for non-agri contracts, with the same brokerage structure. The caveats travel with the venues: currency and commodity trading need the commodity-derivative segment enabled on the account, and the liquidity is thinner than index F&O. The demat-account implications are minimal — currency is always cash-settled, and most commodity contracts close in cash — which is why these corners rarely enter the demat comparison at all, despite the fee advantage being real.

What goes wrong

• Pre-2026 strategy models. Every backtest that used 0.02% futures STT or 0.1% options STT overstates results from April 1, 2026 onward. Re-run the edge with the new rates before re-deploying — the difference is 2.5x on futures STT and 1.5x on options.
• Physical-settlement surprises. An ITM stock option held through expiry delivers shares into your account with a margin call beforehand; unprepared, you meet a shortfall, a 0.10%-class delivery charge and a demat debit you did not plan. Close, roll or make delivery a deliberate strategy.
• Pledge-and-forget. Pledged collateral earns nothing toward the interest cost of the loan it replaces unless you manage it; and unpledging mid-week to sell a holding breaks your margin for the next snapshot. Plan the pledge calendar with the trading calendar.
• Outsourcing discipline to the ₹50 robot. Auto square-offs execute at the worst liquidity minute of the day by design. Exits belong to your order entry, as every broker's own auto-square-off notice implies.

The verdict

F&O trading in 2026 is a thin-margin business with a thick statutory stack: ₹20 brokerage, 0.05% futures STT, 0.15% options STT, exchange transaction charges, and the peak-margin ceiling on leverage. Pick the broker whose platform survives expiry mornings and whose API complies with the 2025 algo framework if you automate; keep the demat account zero-friction for the deliveries that stock contracts spring on you; and size positions against the full statutory stack, because at these rates the government is the counterparty taking the largest fixed share of every trade.
