F&O Trading and Income Tax: What Every Trader Must Know for AY 2026-27

You opened a trading account last year, did a few futures trades on Nifty, made some money in some months, lost in others — and now your CA or the internet is telling you that you need to file something called ITR-3 instead of ITR-2, get books of accounts, maybe even get a tax audit. You're confused. You thought F&O was just like investing in shares.

It isn't. And that confusion is exactly why so many traders get income tax notices.

If you traded in Futures & Options (F&O) during FY 2025-26 — even once, even with a loss — this article explains what the tax rules are, which form you need to file, and what deadlines you absolutely cannot miss.

F&O Income Is Not Capital Gains — It's Business Income

This is the single most important thing to understand. Under Section 43(5) of the Income Tax Act, F&O contracts traded on recognised exchanges like NSE or BSE are classified as non-speculative business transactions. This means the profit or loss goes under the head "Profits and Gains from Business or Profession" (PGBP) — not under capital gains.

Why does this matter? Because:

• The tax rate is your applicable slab rate (not a flat 15% or 20%)
• You can claim business expenses as deductions
• Losses have specific set-off and carry-forward rules
• The ITR form you need to file is different

Non-speculative means the law treats F&O as a legitimate business transaction, not pure gambling. Don't confuse this with intraday equity trading, which is speculative and has different — and stricter — rules.

Which ITR Form to File?

Almost every F&O trader must file ITR-3. This form handles income from business or profession, and also lets you report salary, capital gains, rental income, and other sources in the same return.

If you are salaried and also traded in F&O, you still must file ITR-3 — not ITR-1 or ITR-2. Your salary income is reported in ITR-3 under a separate head. Many traders make the mistake of filing ITR-2 because they are "mostly salaried." The Income Tax Department does not accept this — and more importantly, if you have an F&O loss, it cannot be carried forward from an incorrectly filed return.

Can you use ITR-4 (presumptive taxation)? You may opt for presumptive taxation under Section 44AD if your F&O turnover is within ₹2 crore (extended to ₹3 crore where at least 95% of receipts are through digital modes — which F&O trading effectively always is). Under this route you declare a minimum of 6% of turnover as deemed profit, without claiming actual expenses or carrying forward losses. Think carefully before choosing it. Once you opt in, there is a five-year continuation rule, and opting out early bars you from the scheme for the following five years. If you are making losses, the presumptive route makes no sense at all — you would be paying tax on a notional profit you didn't earn.

How Is F&O Turnover Calculated?

This is the part traders get wrong most often — and getting it wrong can wrongly push you into audit territory or trigger a defective-return notice. So let's go slowly.

First, an important distinction. "Turnover" for tax purposes is not the total value of your contracts. If you bought one lot of Nifty Futures worth ₹20 lakh and sold it, your contract value is ₹20 lakh — but that is not your turnover. The tax department is interested in your business turnover, which is based on the profit and loss you made, not the notional value traded. This is why a trader can have crores in contract value but only a few lakh in tax turnover.

The governing rule comes from the ICAI Guidance Note on Tax Audit (8th edition, applicable from AY 2022-23 onwards). Here is how each segment is treated:

1. Futures turnover Take the profit or loss on each trade, ignore the plus/minus sign (i.e. take the absolute value), and add them all up.

Futures Turnover = Sum of absolute profits + Sum of absolute losses

2. Options turnover The same method now applies to options. Take the absolute value of profit or loss on each options trade and add them up.

Options Turnover = Sum of absolute profits + Sum of absolute losses

Important update on options: Under the older 7th edition of the Guidance Note, you also had to add the premium received on the sale of options to the turnover. This is no longer the case under the current 8th edition (effective AY 2022-23). Provided the premium is already captured in your profit/loss figure — which it is in every modern broker's tax P&L — you do not add it separately. Adding it would massively and wrongly inflate your turnover. If you are reading an old blog or an old CA note that still adds the premium, it is out of date.

3. Intraday F&O / reverse trades Differences on reverse trades (positions squared off) also form part of turnover, computed on the same absolute-value basis.

A worked example. Suppose during the year you made these four trades:

• Nifty Futures: profit of ₹40,000
• Bank Nifty Futures: loss of ₹25,000
• Nifty Options: profit of ₹18,000
• Bank Nifty Options: loss of ₹12,000

Your turnover is the sum of the absolute values: ₹40,000 + ₹25,000 + ₹18,000 + ₹12,000 = ₹95,000

Note that your net profit is only ₹40,000 − ₹25,000 + ₹18,000 − ₹12,000 = ₹21,000. You pay tax on the ₹21,000 (your actual profit), but the ₹95,000 turnover is what decides whether audit and presumptive-scheme thresholds apply. Never confuse the two — turnover decides compliance, net profit decides tax.

Practical tip: You don't have to compute all of this by hand. Every major broker — Zerodha, Upstox, Groww, Angel One, ICICI Direct and others — provides a Tax P&L statement that gives your turnover figure directly. Use it as your starting point, but understand the logic above so you can sanity-check it.

Always cross-check your figures against your AIS (Annual Information Statement) on the Income Tax portal before filing. Brokers report your F&O data to the department and it appears in your AIS. Any mismatch between your return and AIS can trigger an automated notice under Section 143(1).

When Is a Tax Audit Required?

A tax audit (by a Chartered Accountant, under Section 44AB) is mandatory for F&O traders in the following situations:

1. Your F&O turnover exceeds ₹10 crore — audit is mandatory. Because F&O is effectively 100% digital, the higher ₹10 crore threshold applies, not the ordinary ₹1 crore limit.
2. You opt out of presumptive taxation while declaring profit below 6% of turnover (or a loss), AND your total income exceeds the basic exemption limit — audit required under Section 44AB(e).

Point 2 catches many salaried F&O traders off guard. Even if your F&O turnover is small, if you made a loss and your total income crosses the basic exemption limit, an audit may be needed before you can validly claim that loss carry-forward.

What is the "basic exemption limit"? It is ₹4 lakh under the new tax regime (the default for FY 2025-26) and ₹2.5 lakh under the old regime (₹3 lakh for senior citizens, ₹5 lakh for super senior citizens). One important catch for traders: the much-talked-about "no tax up to ₹12 lakh" figure is a rebate (under Section 87A), not the exemption limit. So you can owe zero tax thanks to the rebate and still cross the basic exemption limit — which means the audit trigger in point 2 can apply even when your final tax is nil. Don't let the ₹12 lakh number lull you.

If you skip a mandatory audit and still file, the loss carry-forward claim can be disallowed, and a penalty of 0.5% of turnover (up to ₹1.5 lakh) can be levied under Section 271B.

Note: Audit applicability depends on the specific facts of your case — turnover, profit percentage, your other income, and your past use of the presumptive scheme. If you are anywhere near these thresholds, get it checked rather than guessing.

Setting Off and Carrying Forward F&O Losses

This is actually one area where F&O traders have an advantage over intraday traders.

In the same year, F&O losses (being non-speculative business losses) can be set off against:

• Other business income
• Capital gains — both Short-Term (STCG) and Long-Term (LTCG)
• Rental income, interest income, and other taxable income

One important exception: F&O losses cannot be set off against salary income in the same year.

Remaining losses can be carried forward for up to 8 assessment years and adjusted against future business income. This is a significant tax planning benefit — but only if:

• You file ITR-3 (not ITR-2 or ITR-4)
• You file it on or before the due date — 31st August 2026 for non-audit cases

A crucial catch on carried-forward losses: The wide set-off flexibility described above applies only in the same year the loss is incurred. Once a loss is carried forward to a future year, it can only be set off against future business income (PGBP) — not against capital gains, rental income, or interest. So plan your current-year set-offs wisely.

If you miss the 31st August deadline and file a belated return, you permanently lose the right to carry forward your F&O losses. There is no remedy for this. Even if the department accepts your belated return, the loss carry-forward is gone. This is one deadline that must not be missed. (Note: while salaried individuals filing ITR-1/ITR-2 have a 31st July deadline, business returns like ITR-3 get a staggered deadline of 31st August 2026 for non-audit cases.)

What Expenses Can You Deduct?

Since F&O is treated as a business, you can deduct expenses that are directly related to your trading activity:

• Brokerage charges paid to your broker
• Securities Transaction Tax (STT)
• GST on brokerage
• Exchange transaction charges and SEBI turnover fees
• Internet and data charges (proportionate to trading use)
• Subscription to market data platforms and financial news services
• Depreciation on a laptop or desktop used for trading
• Advisory or consultancy fees paid for trading research

Keep your broker's annual statement and invoices for other expenses. These directly reduce your net taxable F&O profit. (Note: STT, brokerage and GST are expenses — they are never part of turnover.)

A Note on STT and the April 2026 Hike

For the trades you are filing now — those made during FY 2025-26 — STT applied at 0.02% on the sale of futures and 0.1% on the sale of options (on the premium). Use the figures in your broker's tax P&L; STT is a fully deductible business expense.

Going forward, be aware of a significant change. From 1st April 2026 (i.e. FY 2026-27 onwards), STT on F&O was hiked sharply to curb speculative volumes — 0.05% on the sale of futures and 0.15% on the sale of options. This does not affect the return you are filing now, but if you are actively trading this year, your per-trade cost has gone up meaningfully. Remember that STT is charged on transaction value regardless of whether the trade made money — so it applies even to loss-making trades. Combined with SEBI's larger contract sizes over the past year, the cost side of trading has grown. The silver lining: STT stays fully deductible.

Which Tax Regime Applies?

F&O income is taxed at slab rates under whichever regime you file under. The new tax regime is the default for individuals, with lower slab rates but no Chapter VI-A deductions (like 80C, 80D) and no HRA. The old regime allows those deductions but at higher rates.

One point specific to business income: unlike a purely salaried person who can switch regimes every year, a taxpayer with business income (which is what F&O is) has restricted flexibility. If you want the old regime, you generally need to file the prescribed form (Form 10-IEA) before the due date. There is no separate regime for trading income — it follows your overall return. A proper calculation comparing both regimes is worthwhile before filing.

A Quick Checklist Before You File

1. Download your broker's Tax P&L statement for FY 2025-26
2. Confirm F&O turnover is calculated on absolute profit/loss (not contract value, and no separate premium add-on)
3. Download your AIS from the IT portal and match figures
4. Determine if tax audit applies to your situation
5. Choose between actual profit/loss (ITR-3) and presumptive taxation (ITR-4, if eligible)
6. Gather expense records — brokerage, STT, internet, advisory fees
7. File ITR-3 before 31st August 2026 if you have losses to carry forward

F&O taxation is one area where a small error — wrong turnover, wrong ITR form, missed deadline — can have consequences that last years. If your situation involves losses, a salaried income alongside F&O trades, or any uncertainty about audit applicability, it is well worth a conversation with a tax professional before filing.
