F&O and Intraday Tax Audit Checker
Most traders panic about the wrong number. Your turnover is not the notional value of your contracts — and a loss does not automatically mean an audit. Enter your broker P&L figures below and this tool computes your turnover the ICAI way, then tells you clause by clause whether a tax audit applies — for FY 2025-26 under Section 44AB and for FY 2026-27 under the new Section 63, which changes the rules for loss-making traders.
How trading turnover is actually calculated
This is where most traders go wrong. If you sold 200 lots of Nifty futures during the year, the notional contract value runs into crores — but that is not your turnover for tax purposes. The ICAI Guidance Note on Tax Audit prescribes the absolute profit method:
- Futures and options — add up the profit or loss on every trade, ignoring the sign. A ₹38,000 profit and a ₹22,000 loss give a turnover of ₹60,000, not ₹60 lakh.
- Intraday equity — the same absolute-difference method, but it is a separate speculative business under Section 43(5).
- Delivery-based equity — not business turnover at all if you treat it as investment; it is capital gains. Keep it out of this calculation.
When a tax audit actually applies
For FY 2025-26 the Income-tax Act, 1961 applies and there are only two realistic triggers for a trader:
- Section 44AB(a) — total business turnover crosses ₹1 crore, raised to ₹10 crore where cash receipts and cash payments are each 5% or less. Since exchange trading is fully banked, the ₹10 crore limit is the one that matters for nearly every trader.
- Section 44AB(e) — this bites only when Section 44AD(4) applies to you, which requires that you previously declared income under the presumptive scheme and then stopped. If you have never used 44AD, declaring an F&O loss with turnover under the limit does not, by itself, make an audit compulsory.
That second point is the single most misunderstood rule in trader taxation, and it is why the tool asks whether you have ever used 44AD.
Section 44AD: the escape hatch, and its trap
F&O is a non-speculative business, so Section 44AD is available to you if turnover stays within ₹3 crore (₹2 crore where cash exceeds 5%). Declare 6% of turnover as your income, skip detailed books and skip the audit. Intraday equity is excluded — Section 44AD(6) bars speculative business outright, so an intraday-only trader cannot use it at all.
The trap is Section 44AD(4). Once you opt in, you are expected to stay in for five consecutive years. Drop out in year three — because you had a loss and did not want to pay tax on a notional 6% — and you are locked out of 44AD for the next five years, and an audit becomes compulsory in every one of those years in which your income exceeds the basic exemption limit. The tool shows you the extra tax that opting in would cost this year so you can weigh it against the audit fee you avoid.
What happens to your losses
F&O losses
Non-speculative business loss. Set off against any head of income except salary in the same year, then carried forward for 8 assessment years against business income. You lose the carry-forward entirely if the return is filed after the Section 139(1) due date.
Intraday losses
Speculative business loss. Set off only against speculative income, and carried forward for just 4 assessment years. It cannot absorb your F&O profits.
Filing on time is the whole game
A trader with a ₹3 lakh F&O loss and no other business income gains nothing today from that loss — its entire value is the carry-forward, and a late return destroys it.

Frequently asked questions
Is my F&O turnover the total value of contracts I traded?
No. For tax purposes turnover is the absolute sum of profits and losses on each trade, not the notional contract value. A trader who moved crores of notional value can easily have a turnover of only a few lakh rupees.
Do I have to add option premium received to turnover?
Not under the current ICAI Guidance Note. The 8th edition, applicable from AY 2022-23, removed the separate addition of premium received on sale of options where it is already reflected in the profit computation. Older articles and calculators still apply the pre-2022 method and will overstate your turnover.
I made an F&O loss. Is a tax audit compulsory?
Not automatically. For FY 2025-26, if your turnover is within the Section 44AB limit and you have never declared income under Section 44AD, a loss by itself does not trigger an audit. From FY 2026-27, Section 63 of the Income-tax Act 2025 introduces a standalone low-profit trigger, so the answer can change on identical figures.
Can F&O traders use presumptive taxation under Section 44AD?
Yes, because F&O is non-speculative business income and turnover up to 3 crore rupees qualifies where cash receipts are within 5%. Intraday equity trading is speculative and is excluded from 44AD by sub-section (6).
What is the penalty for not getting a tax audit done?
Section 271B provides for 0.5% of total turnover, capped at 1,50,000 rupees. It is not automatic — reasonable cause can be pleaded — but it is a real risk for traders who assume the rules do not apply to them.
Which ITR form do F&O and intraday traders file?
ITR-3, because both are business income. Intraday is reported separately as speculative business, and F&O as normal business income, since their loss set-off rules differ.
What is Form 26 and when does it apply?
Form 26 is the consolidated tax audit report under the Income-tax Act 2025 that replaces Forms 3CA, 3CB and 3CD. It applies from tax year 2026-27 onwards. Audits for FY 2025-26 still use the existing forms under the 1961 Act.
Is this audit checker free?
Yes, completely free with no sign-up, and nothing you type is sent anywhere — the entire calculation runs in your browser.
Disclaimer: This tool is for general information and educational purposes only and is not tax advice. It applies the ICAI absolute-profit turnover method and the audit tests in Section 44AB and Section 44AD of the Income-tax Act, 1961 for FY 2025-26, and Section 63 read with Section 58 of the Income-tax Act, 2025 for FY 2026-27. The FY 2026-27 provisions are new and their interpretation is still developing. The tool ignores surcharge, Chapter VI-A deductions and the finer points of loss set-off, and it cannot see your books.
