Trading Taxation in India 2026: STCG, LTCG, F&O, Intraday, and Reporting

The first conceptual step is understanding that trading income is not one thing. It is four distinct categories, each with its own tax treatment, loss-set-off rules, and reporting requirements. Mixing them up, or reporting the wrong category, produces either higher tax than necessary or problems with the Income Tax Department. The four categories are intraday equity (speculative business), F&O across any asset class (non-speculative business), short-term capital gains (delivery equity held up to 12 months), and long-term capital gains (delivery equity held over 12 months).

Both intraday and F&O are classified as business income, not capital gains. Both are taxed at the trader's applicable slab rate, not at a concessional capital gains rate. But they differ in one critical respect: intraday equity is speculative, while F&O is non-speculative. The distinction matters primarily for loss treatment.

A speculative business, under the Income Tax Act, is one where contracts are settled without actual delivery. Intraday equity trading, which is squared off by end of day, fits this definition. Losses from speculative business can only be set off against other speculative income. They can be carried forward, but only for four assessment years, and only against future speculative income. If you have intraday losses but no intraday profit in the following four years, the loss simply expires unused.

F&O, despite being derivative trading, is explicitly classified as non-speculative under Section 43(5) of the Income Tax Act because the transactions are recognised as business transactions by the exchange. F&O losses get much more generous treatment: they can be set off against any other business income in the same year (consulting income, freelance income, small business profits) and carried forward for eight years against any future business income. For a trader with a salaried job, F&O losses cannot offset salary income, but can offset any side-business income.

The practical implication for retail traders is significant. Intraday losses are harder to recover tax benefit from; F&O losses are comparatively easier. This does not mean trade F&O to game taxes; it means that understanding the difference affects how you report, how you file, and what you can set off.

Delivery-based equity investing — where you buy a stock, hold it for some period, and sell — is classified as capital gains, not business income. Until Budget 2024, the short-term capital gains rate was 15 percent and the long-term rate was 10 percent on gains over one lakh rupees per year. The Finance Act 2024 raised both rates, and these higher rates apply for FY 2024-25 onwards.

Short-term capital gains, where the holding period is twelve months or less for listed equity shares and equity-oriented mutual funds on which STT has been paid, are now taxed at twenty percent flat. This rate applies regardless of your income slab. A retired investor with total income well below the old thirty-percent slab still pays twenty percent on STCG. A high-income investor whose slab would have been thirty percent also pays twenty percent on STCG. The rate is the rate.

Long-term capital gains, where the holding period exceeds twelve months, are taxed at twelve-and-a-half percent on gains exceeding one lakh twenty-five thousand rupees per financial year. The one-and-a-quarter lakh exemption is aggregate, not per trade. If you had four transactions producing LTCG of fifty thousand each across the year, only the cumulative total above one-and-a-quarter lakh is taxed. Importantly, the LTCG exemption is not a deduction against profit, it is a threshold below which the rate does not apply.

Short-term capital losses can be set off against both short-term and long-term capital gains, and carried forward for eight years. Long-term capital losses can only be set off against long-term capital gains, and carried forward for eight years. Both require that the return be filed by the due date to preserve the carry-forward benefit.

STT is a tax levied on every equity and F&O transaction executed on recognised Indian stock exchanges. It is collected by the broker at the time of trade and paid to the government. For FY 2025-26, the prevailing rates are approximately 0.1 percent on the value of delivery-based equity buy and sell, 0.025 percent on the sell side of intraday equity, 0.1 percent on equity options sell (on the premium), and 0.02 percent on the sell side of equity futures. Commodity and currency derivatives have their own STT-equivalent rates under CTT (Commodity Transaction Tax).

STT treatment for tax purposes depends on the category of income. For delivery-based investors (capital gains), STT paid is not separately deductible, but its payment is the trigger that entitles the investor to the concessional STCG and LTCG rates. Without STT-paid status, delivery trades would be taxed at slab rates as non-concessional capital gains, which is substantially higher for most investors. For F&O and intraday traders (business income), STT paid is fully deductible as a business expense, along with brokerage, exchange charges, GST on brokerage, SEBI turnover charges, and stamp duty.

Keeping a running record of STT paid across the year is essential for F&O and intraday traders. Most Indian brokers — Zerodha Kite, Upstox, AngelOne, ICICI Direct — provide a detailed P&L statement and tax P&L report at year-end that breaks these charges out line by line. The tax P&L report is typically available from April for the previous financial year and is the primary document used by a chartered accountant to prepare the trader's return.

Tax audit under Section 44AB is mandatory for certain categories of business income, and F&O trading can trigger it. As of current rules, a tax audit is required if F&O trading turnover exceeds ten crore rupees in a financial year, provided that digital transactions exceed ninety-five percent of total transactions. For most retail F&O traders using regular broker accounts, all transactions are digital, so the threshold in practice is ten crore rupees of turnover.

Turnover for F&O is not the notional value of the contracts traded. It is calculated as an absolute value metric. For options, turnover equals the absolute sum of profit and loss on each trade, plus the premium received on the sell side of all option contracts. For futures, turnover equals the absolute sum of profit and loss on each trade. A trader with one crore rupees of cumulative absolute P&L across the year on F&O has one crore rupees of turnover, not one crore of notional contract value.

The ten-crore threshold is easier to cross than most retail traders realise, especially for active intraday F&O participants who enter and exit many positions per day. A trader with an average of twenty trades per week across Nifty and Bank Nifty options, each producing a few thousand rupees of absolute P&L plus option premium on sells, can cross ten crore turnover within a year. This is why understanding the turnover calculation at the start of the year, not at the end, matters.

Tax audit is not a punishment. It is a procedural requirement that mandates professional preparation of the accounts by a chartered accountant. The cost is typically fifteen thousand to thirty-five thousand rupees depending on complexity. Traders crossing the threshold should budget for this and engage a CA by January at the latest to avoid the rush near the September 30 audit deadline.

Traders with F&O or intraday activity file ITR-3, which is the form for income from business and profession. This holds even if the trading produced a loss for the year; the loss must be declared in the return to be carried forward. Traders with only delivery-based equity (STCG and LTCG, no F&O or intraday) can file ITR-2, which covers capital gains but not business income.

The ITR filing deadline for FY 2024-25 is typically July 31, 2025 for individuals not requiring tax audit, and October 31, 2025 for those requiring audit. Both deadlines are subject to year-to-year extensions which are sometimes granted by the government. The critical rule for traders is that loss carry-forward benefits are preserved only if the return is filed by the due date. A trader with significant F&O losses who filed the return even one day late forfeits the right to carry those losses forward against future income. This single administrative oversight has cost retail traders substantial amounts in forgone tax benefit over the years.

For traders who are salaried employees, the return combines salary income (reported by the employer on Form 16) with trading income or loss (reported by you from broker tax P&L). The process is more complex than a salary-only return and justifies professional help. A reasonable rule of thumb is that if your trading activity in the year involved more than twenty F&O transactions, more than fifty delivery transactions, or any intraday activity, engaging a CA is worth the fee. The fee is deductible as a business expense for business-income categories.
