Intraday Trading & F&O Income Tax in India: How Day Trading and Derivatives Are Taxed (AY 2026-27)

If you trade stocks intraday or deal in futures and options (F&O), your tax treatment is fundamentally different from someone who buys and holds shares. Delivery-based trades generate capital gains. But intraday and F&O profits are classified as business income — and this distinction changes everything: the ITR form you file, the deductions you can claim, the losses you can carry forward, and whether you need a tax audit.

This guide explains exactly how intraday and F&O income is taxed for AY 2026-27, with practical examples and the compliance steps most traders get wrong.

The Three Categories of Stock Market Income

Before anything else, you need to know which bucket your trades fall into:

The key insight: delivery-based trading is covered under the capital gains head. If that is your only market activity, you file ITR-2 and the rules are relatively simple — see our guide to capital gains on stocks and mutual funds. But the moment you have intraday or F&O activity, you enter business income territory.

Intraday Trading: Speculative Business Income

When you buy and sell the same stock on the same day without taking delivery, the profit or loss is treated as speculative business income under Section 43(5) of the Income Tax Act.

How it is taxed

Speculative income is added to your total income and taxed at your applicable slab rate. There is no flat rate like the 20% for short-term capital gains on equity.

Example: Neha earns Rs 8,50,000 from her salaried job and makes Rs 1,20,000 from intraday trading during FY 2025-26. Her total income becomes Rs 9,70,000 and the intraday profit is taxed at her marginal slab rate under the new regime.

Speculative loss rules

This is where intraday traders often get caught off guard:

• Speculative losses can only be set off against speculative income — not against salary, capital gains, F&O income, or any other head
• Unabsorbed speculative losses can be carried forward for 4 assessment years
• You must file your ITR before the due date (31 July for non-audit cases) to carry forward speculative losses

So if you lose Rs 2,00,000 in intraday trading and earn Rs 15,00,000 from salary, you cannot reduce your salary income by the trading loss. That Rs 2,00,000 sits idle unless you have speculative gains in the current or next four years to absorb it.

F&O Trading: Non-Speculative Business Income

Futures and options are explicitly excluded from the definition of speculative transactions by a proviso to Section 43(5), provided the trades happen on a recognised stock exchange. This makes F&O profit or loss non-speculative business income.

How it is taxed

Like intraday, F&O income is taxed at slab rates. But the loss treatment is far more flexible.

F&O loss set-off rules

• F&O losses can be set off against any income head except salary — including rental income, interest income, and capital gains
• Unabsorbed F&O losses can be carried forward for 8 assessment years
• Filing before the due date is mandatory to carry forward

For a deeper look at how loss set-off works across income heads, see our guide to set-off and carry forward of losses.

Example: Rohan has a salaried income of Rs 12,00,000, rental income of Rs 3,00,000, and an F&O loss of Rs 4,50,000. He can set off the F&O loss against rental income (Rs 3,00,000), reducing it to zero, and carry forward the remaining Rs 1,50,000 to future years. He cannot touch the salary income.

How to Calculate Turnover for F&O

Turnover is a critical number — it determines whether you need a tax audit and whether you qualify for presumptive taxation. But F&O turnover is not the total contract value. The Income Tax Department and ICAI guidance use this formula:

Example: You trade Nifty futures and make profits of Rs 50,000 on some trades and losses of Rs 30,000 on others. Your futures turnover is Rs 50,000 + Rs 30,000 = Rs 80,000 (the absolute sum, not the net Rs 20,000).

Most brokers like Zerodha and Groww provide a tax P&L report that calculates turnover for you. Download it before filing — computing turnover manually from hundreds of trades is impractical.

For intraday trading, turnover is simply the absolute sum of trade-wise differences (profit or loss), similar to futures.

Tax Audit: When Section 44AB Kicks In

You need a tax audit under Section 44AB if:

1. Turnover exceeds Rs 10 crore and 95% or more of your receipts and payments during the year are through banking channels (UPI, net banking, broker settlement — which covers almost all F&O traders)
2. Turnover exceeds Rs 1 crore if more than 5% of transactions are in cash (rare for F&O traders)
3. You opted for presumptive taxation under Section 44AD in an earlier year, declared profits below 6%/8%, and your income exceeds the basic exemption limit

For most retail F&O traders, the relevant threshold is Rs 10 crore. If your F&O turnover is below this, you are generally not required to get a tax audit — but you must still maintain books of accounts if your income exceeds Rs 2,50,000 or turnover exceeds Rs 25 lakh in any of the three preceding years.

Tax audit deadline

The due date for filing ITR with tax audit is 31 October 2026 (for AY 2026-27), not 31 July. If you need a tax audit, you get extra time — but you also need to engage a Chartered Accountant, which adds cost.

Presumptive Taxation for F&O Traders (Section 44AD)

If your F&O turnover is within Rs 3 crore (when 95%+ of receipts are digital, which is typical for exchange-traded F&O) or Rs 2 crore otherwise, you can opt for presumptive taxation under Section 44AD.

Under presumptive taxation:

• You declare a minimum profit of 6% of digital turnover and 8% of cash turnover (or your actual profit, whichever is higher)
• No requirement to maintain detailed books of accounts
• No tax audit needed (unless you declare profits below the 6%/8% threshold)
• File ITR-4 instead of ITR-3

Example: Kavitha's F&O turnover for FY 2025-26 is Rs 45,00,000 (entirely digital). Under presumptive taxation, she must declare minimum profit of 6% = Rs 2,70,000. If her actual profit was Rs 5,00,000, she declares Rs 5,00,000. If her actual profit was only Rs 1,00,000, she can still declare Rs 1,00,000 — but this triggers a tax audit requirement since it is below 6%.

Presumptive taxation is available for F&O income but not for intraday (speculative) income. If you have both, the intraday portion must be reported separately under speculative business income. For a complete overview, see our presumptive taxation guide.

Expenses You Can Deduct Against Trading Income

When computing business income from intraday or F&O, you can deduct legitimate business expenses:

• Brokerage and commission paid to your broker
• Exchange transaction charges and SEBI turnover fees
• Internet and phone bills (proportionate, if used for trading)
• Subscription costs for trading software, data feeds, or charting platforms
• Depreciation on computer or equipment used for trading
• Advisory or research fees paid to SEBI-registered advisors

Not deductible: Securities Transaction Tax (STT) is not allowed as a business deduction under Section 40(a)(ib) when income is treated as business income on which STT has been paid.

Advance Tax Obligations

Since your broker does not deduct TDS on trading profits, you are responsible for paying advance tax if your total tax liability exceeds Rs 10,000 in the financial year. The quarterly due dates are 15 June, 15 September, 15 December, and 15 March.

Missing advance tax payments attracts interest under Sections 234B and 234C. Many traders overlook this because they are used to TDS being handled by employers. If your F&O or intraday profits are significant, estimate your tax liability early and pay in instalments.

Which ITR Form to File

If you have any intraday or F&O activity — even a single trade — you cannot file ITR-1 or ITR-2. You must move to ITR-3 (or ITR-4 for presumptive F&O only). This is one of the most common filing errors: traders reporting F&O gains under "Income from Other Sources" in ITR-1 to avoid the complexity of ITR-3. This is incorrect and can trigger a defective return notice.

Actionable Takeaway

Download your broker's tax P&L statement — it gives you turnover, profit/loss, and expense breakdowns in a format that maps directly to your ITR schedules. Classify your trades correctly (delivery vs intraday vs F&O), check if your turnover triggers an audit, and pay advance tax quarterly if your liability exceeds Rs 10,000. Getting the classification right is the single most important step — everything else follows from it.
