Here's the number nobody puts on a trading ad: SEBI says 91% of retail F&O traders lose money. If you're in that 91%, you probably did the most natural thing in the world — skipped your tax return, because what's the point if you didn't make anything?
That single decision can cost you more than the trading did. File your loss correctly and it shelters up to 8 yearsof future profits from tax. Skip it, and that shield is gone — one trader who lost ₹3 lakh and didn't file later paid about ₹90,000in avoidable tax on the very next year's gains. Let's make sure that isn't you.
Do you need a tax audit?
Your trading turnover for the year
Turnover = the absolute sum of your profits and losses (see below) — not your contract value.
No tax audit needed
No tax audit needed. Just file ITR-3 with your actual trading profit and loss — no CA required.
Deadline: 31 August 2026 — and file on time to carry your losses forward.
A quick guide for the common cases, not a ruling — edge cases exist (very high income under 44AD, mixed cash dealings). Confirm yours with a CA before filing.
First, the thing most people get wrong: it's business income
F&O and intraday are not capital gains. The tax department treats trading as a business, so it goes in ITR-3 and is taxed at your normal slab rate — there's no flat 15% or 20% “trading rate.” Your net profit simply stacks on your salary and other income. (Which also means the capital-gains calculator isn't the right tool here — your slab and regime are.)
Within that, there's one split that changes everything about your losses: F&O is non-speculative, while intraday equity — buying and selling shares the same day without taking delivery — is speculative. Here's what that means in practice:
| F&O | Intraday equity | |
|---|---|---|
| Counts as | Non-speculative business income | Speculative business income |
| Set off against | Any income except salary (business, capital gains, rent, interest) | Only other speculative profit |
| Carry forward | 8 years | 4 years |
| Carry forward needs | Return filed by the due date | Return filed by the due date |
8 years
How long an F&O loss can be carried forward to wipe out future profits — but only if you file your ITR by the due date. A belated return loses it.
The loss rules that quietly save you money
This is the part worth real cash. In the sameyear, an F&O loss can be set off against almost any income except salary — your capital gains, rental income, interest, even a freelance side income. Whatever's left over carries forward 8 years. An intraday loss is stricter: it only offsets other speculative gains, and carries forward 4 years.
But there's a hard condition under all of it: you must file your return by the due date— 31 August 2026 if you're not under audit. File late, and you can still report the loss, but you lose the right to carry it forward. That deadline is the single most valuable thing in this guide.
Turnover — the number everyone calculates wrong
“Turnover” in F&O does not mean the value of your contracts (those run into crores fast). For tax, turnover is the absolute sum of your profits and losses— add up every trade's gain and every trade's loss as positive numbers. A ₹40,000 profit and a ₹25,000 loss make a turnover of ₹65,000, not lakhs.
And the trap that's still wrong on half the internet: the old method also added the premium on options sales to turnover. The revised ICAI Guidance Note (2022) dropped that — options turnover is now just the absolute profit and loss, which typically cuts it 40–60%. Use the old method and you'll scare yourself over an audit threshold you never actually crossed.
Cut the tax: expenses, advance tax and the STT hike
Because it's a business, you deduct your trading costs beforearriving at taxable profit: brokerage and its GST, STT, exchange and SEBI fees, plus a fair share of your internet, electricity, phone, laptop depreciation, and any charting or advisory subscriptions. These are real deductions most casual traders forget.
Two things to diarise. First, brokers deduct no TDS on your profits, so if your total tax for the year tops ₹10,000 you must pay advance tax in four installments (15 Jun, 15 Sep, 15 Dec, 15 Mar) — miss it and 1% a month of interest stacks up under Sections 234B and 234C. Second, since 1 October 2024 the STT on selling options rose to 0.1% of premium (from 0.0625%) and on futures to 0.02%— a higher cost, but at least it's a deductible one here.
For 91% of traders the tax question isn't “how much do I owe?” — it's “am I throwing away a loss that could wipe out next year's tax?”
What it means for you
Honest take: if you trade F&O or intraday, filing isn't optional and it isn't scary. Get three things right and you're done — file ITR-3 (not ITR-1/2), report your real turnover the absolute-P&L way, and file by 31 August 2026so your losses carry forward. For most people there's no audit and no CA— the decider above shows whether you're one of them.
Then handle the money side: see which tax regime costs less once your trading profit stacks on your income, confirm ITR-3 is really your form, and reconcile your AIS (it already lists your trades) before you submit. Do that, and a losing year at least buys you a tax shield for the winning ones.
For AY 2026-27 (FY 2025-26). Classification, turnover, audit and deadline rules are based on the Income Tax Act, the ICAI Guidance Note and the e-filing portal at the time of writing, and can change; audit and 44AD edge cases depend on your full facts.
