How Your Trading Income Gets Taxed: F&O, Intraday and Stock Trades Explained

Retail participation in the stock market has boomed in recent years, and a large part of that boom is coming from active trading — derivatives (futures and options, or F&O), intra-day trading, and frequent buying and selling of stocks. More trading, however, comes with more tax compliance.

Here's the part many traders get wrong: all trading income must be reported in your income tax return (ITR), even if you made only losses. Because F&O and intra-day trades don't show up in your Annual Information Statement (AIS) the way salary or interest income does, many traders assume these need to be reported only when there's a profit. That isn't true — since these trades involve numerous high-value transactions, they must be disclosed regardless of the outcome.

This article breaks down how each type of trading income is classified, which ITR form applies, when an audit kicks in, and how losses can be set off.

The big picture

Note: The tax audit threshold is ₹1 crore turnover. It rises to ₹10 crore if cash receipts and cash payments each stay within 5% of their respective totals (i.e., the business is almost entirely digital) — this applies uniformly, regardless of whether you're an individual, firm, or company.

Futures and options (F&O)

Trading in derivatives is treated as business income, reported in ITR-3, or ITR-4 if you opt for the presumptive taxation scheme. Depending on your turnover and income, you may also need to maintain books of accounts or get a tax audit done.

When books of accounts are required: You need to maintain a profit and loss (P&L) statement when F&O turnover exceeds ₹25 lakh, or income exceeds ₹2.5 lakh — and both thresholds must be checked against the last three financial years, not just the current one. So if your turnover was below ₹25 lakh this year but crossed it in an earlier year, you still need to keep accounting records now. You don't need a chartered accountant for this — the P&L statement provided by your broker is usually sufficient.

How turnover is calculated: Turnover for F&O is the net sum of profits and losses across all trades in the year — not the total value of contracts bought and sold. This clarification came from a 2022 guidance note by a professional accounting standards body, which excluded the sale value of options from the turnover calculation. That was a relief for traders, since including the full sale value could easily push turnover past the audit threshold even for modest trading activity. It's worth noting this comes from a guidance note rather than a tax law itself, so it isn't strictly binding on the tax department, and there have been isolated cases where the interpretation was disputed. Most tax practitioners still recommend following it.

When a tax audit is mandatory:

• Turnover exceeds ₹1 crore — unless cash receipts and cash payments each stay within 5% of their respective totals, in which case the threshold rises to ₹10 crore, or

• You've opted out of the presumptive taxation scheme within the last 5 years

The presumptive scheme itself is available if turnover doesn't exceed ₹2 crore (₹3 crore for mostly-digital receipts), letting you declare 6-8% of turnover as taxable profit without detailed books. Opting in commits you for five years — exiting early triggers an audit for that year, and for the next five if your income exceeds the basic exemption limit.

Skipping a mandatory audit attracts a penalty of 0.5% of turnover, capped at ₹1.5 lakh.

Expenses you can claim: Trading expenses like securities transaction tax (STT), demat charges and brokerage, plus indirect expenses such as subscriptions to trading courses, websites or publications, trading software fees, and depreciation on the laptop or phone used for trading.

Setting off F&O losses: These can be set off against rent, other business income, interest, and capital gains — but not against salary. Unused losses can be carried forward for up to eight years. From the second year onward, though, the options narrow considerably: carried-forward F&O losses can only be set off against business income, not against capital gains, other income, or rent.

Intra-day trading

Buying and selling the same stock within a single trading day is intra-day trading. Like F&O, this counts as business income — but it's classified as speculative business, while F&O is treated as non-speculative (possibly because derivatives are also used for hedging, not just speculation).

This distinction matters a lot for losses:

• Losses from speculative business (intra-day) can only be set off against other speculative income, such as gains from gambling or horse racing.

• These losses can be carried forward for only 4 years, compared to 8 years for F&O.

Turnover calculation, audit thresholds, and eligible expenses for intra-day trading follow the same rules as F&O.

Delivery-based stock trading: capital asset or business?

When you buy shares and hold them for at least a day before selling (delivery-based trading), the tax treatment depends on how frequently you trade — not on how large your profits are.

There's no hard-and-fast legal definition, but a widely used rule of thumb is:

• Frequent trading, primary income source → treat as business income

• Occasional trades (say, fewer than ten a year) → treat as capital gains

This classification has a real impact on how you file and what you can claim:

Under the capital-gains route, short-term gains (shares held up to 12 months) are taxed at 20%, and long-term gains at 12.5% — with the first ₹1.25 lakh of long-term gains in a financial year exempt from tax.

A word of caution: don't pick the capital-gains route just because it offers a lower tax rate. The classification should reflect your actual trading pattern, not tax optimisation. Declaring frequent, primary-income trading as "capital gains" is a common red flag for tax scrutiny, and such cases are more likely to end up disputed — and potentially in litigation — if questioned by the tax department.

Setting off losses at a glance

Losses can generally be set off within the same head of income too (e.g., F&O loss against other business income). Carry-forward rules differ by category, as noted above, and unused losses lapse if not carried forward within the applicable time limit.

A quick illustration

Consider a salaried professional who trades on the side. In one financial year, they made a loss of ₹5 lakh in F&O, plus a capital gain of ₹7 lakh from selling shares in two companies. Because they made only a handful of stock trades in the year, those stock gains genuinely qualify as capital gains rather than business income. Since they also traded F&O (a business activity), they must file ITR-3. The good news: the ₹5 lakh F&O loss can be set off against the ₹7 lakh capital gains, leaving a net taxable capital gain of ₹2 lakh.

(This is a simplified, hypothetical example for illustration only; actual outcomes depend on individual facts.)

Key takeaways

• Report every trade — F&O, intra-day, and stock trading — in your ITR, whether it resulted in profit or loss.

• F&O is non-speculative business income; intra-day is speculative business income. This single distinction drives very different loss set-off and carry-forward rules.

• Turnover for F&O and intra-day is based on net profit/loss, not the total value traded.

• Audit is triggered by crossing turnover thresholds or exiting the presumptive scheme early — plan your books accordingly.

• Whether delivery-based stock trading is a "capital asset" or "business" should be decided by how often you trade, not by which option taxes you less.
