Transaction Costs and Taxation

You buy one NIFTY future, the market moves your way by ten points, you close the trade pleased with yourself, and yet your account is slightly smaller than a simple ten-point gain would suggest. Nothing went wrong. You just met the quiet truth that every futures trader has to learn early: a round trip is never free. Between the moment you buy and the moment you sell, a small stack of charges is taken out, and a separate reckoning with the tax department waits at the end of the year. Neither is large enough to scare you off, but both are large enough to ruin you if you ignore them. This chapter walks through the cost stack first, with real verified numbers, and then through how India taxes what you make.

The costs hiding inside every trade

When you trade a future, several different parties take a tiny slice. Your broker charges a fee for executing the order. The government collects a transaction tax and a stamp duty. The exchange charges for the use of its matching system. The market regulator takes a sliver. And on top of some of those, a goods and services tax is applied. None of these is hidden in a dishonest way, but they are spread across so many lines that a beginner rarely adds them up until they bite.

The single most important thing to understand is that most of these charges are a percentage of turnover, not a flat fee. Turnover here means the rupee value of what you traded, counting both the buy leg and the sell leg. Only the brokerage at a typical discount broker is flat. Everything else grows as your trade size and the contract price grow.

Here are the components on an NSE futures trade, in plain words:

• Brokerage. A typical discount broker charges a flat fee of about Rs 20 per executed order. A round trip is two orders, one to enter and one to exit, so that is about Rs 40 in total. Notice it does not change whether you trade one lot near 24,000 or a far pricier contract. It is a fixed fee, not a percentage.
• Securities Transaction Tax (STT). Charged at 0.05% on the sell-side value of the trade only. You pay it when you close a long or open a short, on the rupee value of that selling leg.
• Exchange transaction charges. Roughly 0.0019% of turnover, paid to the exchange for matching your order.
• SEBI charges. A tiny 0.0001% of turnover, paid to the market regulator.
• Stamp duty. 0.002% on the buy side only, collected by the state government.
• GST. Goods and services tax at 18%, but charged only on the sum of brokerage plus exchange transaction charges plus SEBI charges. It is a tax on the service fees, not on your whole turnover.

One NIFTY lot, start to finish

Numbers turn this from a list into a lesson. Take our standard NIFTY anchor: one lot of 65, bought and sold near 24,000. Each leg is worth about Rs 15,60,000, so the round-trip turnover is about Rs 31,20,000. Here is exactly what comes out.

Charge	One NIFTY lot, bought and sold near 24,000
Turnover (both legs)	about Rs 31,20,000
Brokerage	Rs 40
STT	Rs 780
Exchange transaction charges	Rs 57.10
GST	Rs 18.04
SEBI charges	Rs 3.12
Stamp duty	Rs 31
Total cost of the round trip	about Rs 929
Points the future must move just to break even	about 14.3 points

Sit with that last line, because it is the whole point of the chapter. Before you make a single rupee of profit, NIFTY has to move about 14 points in your favour just to cover the cost of trading one lot. If the future moves up only ten points and you close, the costs eat the gain and you finish slightly down even though your direction was right. The market does not owe you those 14 points. You have to earn them before the trade is even level.

Notice also which charge dominates. STT at Rs 780 is by far the biggest piece, and it is a straight percentage of the sell value. The flat brokerage of Rs 40 is almost an afterthought by comparison. This is why the percentage charges, not the broker fee, decide your real cost on most trades.

Costs grow with turnover

Because most of the stack is a percentage, your costs rise as either the contract price or the number of shares rises. The brokerage stays flat, but STT and the exchange, SEBI and stamp charges all swell with turnover. Two stock-future examples make this vivid.

Take a single-stock future of 500 shares trading near Rs 1,000. The round-trip cost works out to about Rs 330, which across 500 shares is only about 0.66 points. The future has to move barely two-thirds of a rupee in your favour to break even.

Now take the same 500 shares, but on a stock trading near Rs 10,000. The turnover is ten times larger, and the cost climbs to about Rs 2,875, which is about 5.75 points across the 500 shares. Same quantity, same flat brokerage, but the percentage charges have grown nearly ninefold because the rupee value of the trade is ten times bigger.

Contract	Round-trip cost	Cost in points
500 shares near Rs 1,000	about Rs 330	about 0.66 points
500 shares near Rs 10,000	about Rs 2,875	about 5.75 points
One NIFTY lot near 24,000	about Rs 929	about 14.3 points

There is no trick to escape this, only discipline. Trade fewer, better trades, and size your target so it comfortably clears the cost hurdle. Tools like OpenAlgo let you watch your fills and review an order book and trade book, so the costs of a session are something you can see and account for, not a nasty surprise at month end.

How futures profits are taxed

Costs come out trade by trade. Tax arrives once a year, and it treats futures very differently from how it treats shares. This part is India-specific and it matters.

Income from trading futures is non-speculative business income. That phrase has weight. Intraday buying and selling of equity shares is treated as speculative business income, but futures and options traded on a recognised stock exchange are specifically carved out of the speculative category by the Income Tax Act (the proviso to Section 43(5)), so they count as non-speculative business income whatever way they settle. Because it is business income, you report it in ITR-3, the return form for business and professional income, and not as capital gains.

The practical consequence is simple and slightly disappointing. Your futures profit is added to all your other income for the year, such as salary, interest or rent, and the total is taxed at your normal slab rate. There is no special lower rate for futures the way there is for some long-term capital gains, and the STT you paid along the way gives you no rebate against the tax.

Setting off losses and the audit question

Losses in a business are not wasted, and this is where the non-speculative label earns its keep. A non-speculative business loss can be set off against most other heads of income in the same year, with the important exception of salary. So a bad year in futures can reduce the tax on your other business or rental income that year.

If the loss is larger than what you can absorb in the same year, the unabsorbed part can be carried forward for eight years and set off against future business profits. There is one firm condition: you must file your return on time. Miss the filing deadline and you forfeit the right to carry that loss forward, which can be an expensive piece of carelessness.

Two more ideas you should at least recognise:

• Turnover for the tax-audit test. This turnover is not the contract value you traded. For futures and options it is computed roughly as the sum of your absolute profits and losses, adding the size of each gain and each loss regardless of sign. A chartered accountant may need to audit your accounts if this turnover crosses the prescribed threshold, or if you declare profits below the presumptive level the law expects. Whether an audit applies depends on your exact figures, so it is a question to settle with a professional rather than guess.
• Advance tax. Tax is not only paid at year end. If your total tax for the year is above a small threshold, it is payable in instalments through the year, on dates set by the rules. Skipping these instalments invites interest, so an active trader budgets for advance tax rather than facing a lump sum and a penalty in one go.

I have deliberately not quoted exact slab percentages, thresholds or instalment dates, because these change from year to year in the budget. Learn the structure, which is stable: business income, ITR-3, slab rate, set-off, carry-forward, audit test, advance tax. Look up the current figures, or have your accountant supply them, each year.

The takeaway from both halves is the same kind of sobriety. Costs are small per trade but certain and repeated, so they reward patience and punish churn. Tax is the ordinary tax on a business you happen to run from a screen, not a special favour for traders. Trade fewer and better, keep clean records of every fill, file on time, and let a good chartered accountant handle the rest.
