F&O Turnover for Tax Audit: How to Calculate It the ICAI Way, and the Audit Limit for FY 2025-26

Ask three traders what their F&O turnover was last year and you will get three answers: the notional value of every contract they traded, the number printed in their broker’s tax report, and a shrug. Only one method is correct for the Income-tax Act, and it produces a figure that is usually a small fraction of the first answer. That figure decides three things: whether you need a tax audit under Section 44AB, whether presumptive taxation under 44AD is a gift or a trap, and how large a penalty you face if you get either wrong.

This guide sets out the method the Institute of Chartered Accountants of India prescribes, works a realistic example, states the FY 2025-26 audit limit, and explains the single rule — Section 44AD(4) — that is the real reason most F&O traders end up needing an audit.

Turnover is not contract value

A single Nifty futures lot carries a notional value of roughly ₹18 lakh at current levels. A trader who buys and sells one lot a day for a year has traded contracts worth well over ₹40 crore. None of that is turnover.

For the purposes of Section 44AB, the ICAI’s Guidance Note on Tax Audit (2022 revised edition, applicable from AY 2022-23 onwards) defines turnover for derivatives as the sum of the absolute values of the profit or loss on each transaction — the favourable and unfavourable differences added together, ignoring sign. The contract value, the margin, and the premium paid are not turnover. What you made or lost on each trade is.

Instrument	Turnover under the ICAI method
Futures — equity, index, currency, commodity	Absolute value of the profit or loss on each squared-off or expired position, summed
Options — bought or sold	Absolute value of the profit or loss on each position, summed. Premium received on options sold is not added separately where it is already reflected in the profit or loss — which, on any modern broker’s tax P&L, it is
Reverse trades where the difference is settled	The difference, absolute, summed
Intraday equity (speculative)	Absolute value of the difference on each day-trade, summed — kept separate from F&O
Delivery-based equity	Not F&O turnover. Sale value is relevant only if you hold shares as stock-in-trade rather than as investments

The pre-2022 edition of the Guidance Note directed that premium received on sale of options be added to turnover. The revised edition removed the double-count: if the premium is already part of the profit or loss figure, it is counted once, through that figure. Many online calculators and some broker reports still apply the older method, which inflates option-writers’ turnover materially.

A worked example

Facts: Retail trader, FY 2025-26, six positions during the year, all through one broker, all settled digitally.

#	Position	Result	Absolute value (turnover)
1	Nifty futures, long, squared off	Profit ₹40,000	₹40,000
2	Bank Nifty futures, short, squared off	Loss ₹25,000	₹25,000
3	Nifty call option sold at ₹30,000 premium, bought back at ₹18,000	Profit ₹12,000	₹12,000
4	Nifty put option bought at ₹20,000 premium, expired worthless	Loss ₹20,000	₹20,000
5	Crude oil futures, long, squared off	Loss ₹55,000	₹55,000
6	Bank Nifty put option bought and sold	Profit ₹8,000	₹8,000
	Net profit / (loss)	(₹40,000)
	Turnover		₹1,60,000

Notional contract value across these six positions: in the region of ₹8 crore. Turnover for Section 44AB: ₹1.6 lakh. Net result: a loss of ₹40,000.

Note position 3. The premium of ₹30,000 received on writing the call is not added to turnover as a separate item — the position’s profit of ₹12,000 already reflects it. Under the pre-2022 method this trader’s turnover would have been overstated by ₹30,000.

The audit limit for FY 2025-26

Section 44AB requires a tax audit where business turnover exceeds ₹1 crore — raised to ₹10 crore where cash receipts and cash payments are each 5% or less of the totals. Every F&O trade is settled through the exchange and the broker by bank transfer, so the cash condition is satisfied automatically, and the effective limit for F&O traders is ₹10 crore of ICAI-method turnover.

Against that limit, the trader above is at 1.6% of the threshold. A trader would need absolute profits and losses summing to ₹10 crore in a year — an active professional, not a retail account — to cross it. On turnover alone, the overwhelming majority of retail F&O traders do not need a tax audit.

And yet a great many of them are told they do. The reason is not Section 44AB(a). It is Section 44AD.

The 44AD trap: where F&O audits actually come from

F&O trading is a business, not a profession, so Section 44AD — presumptive taxation at 6% of turnover for digital receipts — is available to an F&O trader. On a turnover of ₹1.6 lakh, 44AD deems a profit of ₹9,600, which is a bargain against a loss of ₹40,000 that you cannot carry forward anyway under presumptive rules. So traders opt in.

Three problems follow.

First, the deemed profit scales with turnover, not with results. A trader with ₹2 crore of ICAI turnover is deemed to have earned ₹12 lakh — and pays tax on it — even in a year of heavy losses. The arithmetic that looked generous at ₹1.6 lakh is punitive at ₹2 crore, and turnover under the absolute method grows fast in a volatile year.

Second, Section 44AD(4). Once you have opted for 44AD, if in any of the next five years you declare profit below the presumptive rate — which is what declaring an actual loss means — you are barred from 44AD for the following five years, and Section 44AB(e) then requires a tax audit in that year if your total income exceeds the basic exemption limit. This is the rule behind the widely repeated claim that “an F&O loss means a tax audit.” It is true only for a trader who previously opted for 44AD. A first-time trader declaring a loss on ITR-3, who has never opted for presumptive taxation, does not need an audit on this ground.

Third, presumptive taxation forfeits the loss. Under 44AD there is no loss to carry forward. Declared on ITR-3 with a simple profit-and-loss account, the same ₹40,000 sets off against capital gains and other income in the year and carries forward for eight years.

Situation	Audit required?	Basis
Turnover ₹10 crore or less; never opted for 44AD; declaring actual profit or loss on ITR-3	No	44AB(a) not triggered; 44AD(4) not applicable
Turnover ₹10 crore or less; opted for 44AD in an earlier year; now declaring a loss or profit below 6%; total income above the basic exemption	Yes	44AD(4) read with 44AB(e)
Turnover above ₹10 crore	Yes	44AB(a)
Opting for 44AD this year and declaring 6% or more	No	Presumptive — but the five-year commitment begins

Our advice to almost every retail F&O trader is the same: do not opt for 44AD. File ITR-3, declare the actual result, keep the loss, and keep your options open. The one-year saving is small; the five-year exposure is not.

What “books of account” means for a trader

Section 44AA requires an individual carrying on business to maintain books where income exceeds ₹2.5 lakh or turnover exceeds ₹25 lakh in any of the three preceding years. For an F&O trader this is far less onerous than it sounds. The broker’s contract notes, the broker’s tax profit-and-loss statement, the ledger, and the bank statement together constitute the books. The work is in reconciling them — every position in the broker’s P&L to a contract note, and the net cash movement to the bank — and in computing turnover on the ICAI method rather than accepting whatever “turnover” field the broker’s report happens to show.

Deadlines and the cost of getting it wrong

Where an audit is required, the report in Form 3CB-3CD is due by 30 September following the financial year, and the return by 31 October — subject to any CBDT extension in a given year. For FY 2025-26 that means the audit season is under way as this is written.

Failure to obtain a required audit attracts a penalty under Section 271B of 0.5% of turnover, capped at ₹1.5 lakh. Filing on ITR-2 to avoid the business schedules produces a defective return under 139(9). And a return with no F&O schedule at all, against an AIS full of derivative contracts, produces the mismatch notice described in our guide to unreported stock-market income.

The errors we correct most often

• Using contract or notional value as turnover. This is the single most common mistake, and it turns a ₹1.6 lakh figure into ₹8 crore — sometimes pushing a trader into an audit they never needed, or into a 44AD deemed profit that bears no relation to reality.
• Adding option premium on top of the option’s profit or loss. Double-counting under the superseded method.
• Forgetting expired positions. An option that expires worthless is a loss equal to the premium paid, and it counts.
• Mixing intraday equity into F&O. Intraday is speculative business; it is computed the same way but reported separately, and its losses carry forward for only four years against speculative income.
• Accepting the broker’s “turnover” without checking the method. Some reports use contract value; some use the old ICAI method; some are correct. Reconcile before you rely on it.
• Opting for 44AD “just this year.” There is no such thing. The commitment is five years, and the exit triggers an audit.

Frequently asked questions

What is the F&O turnover limit for tax audit in FY 2025-26?

₹10 crore of turnover computed on the ICAI method — the sum of absolute profits and losses — because F&O trades are settled digitally and therefore meet the 5% cash condition that raises the ordinary ₹1 crore limit. Contract value is irrelevant.

How do I calculate F&O turnover?

Add up the absolute value of the profit or loss on every futures and options position closed or expired during the year, ignoring whether each was a gain or a loss. Do not add option premium separately where it is already reflected in the position’s profit or loss. Do not use contract value.

I made a loss in F&O. Do I need a tax audit?

Not merely because of the loss. An audit is required only if your ICAI-method turnover exceeds ₹10 crore, or if you opted for Section 44AD in an earlier year and are now declaring below the presumptive rate with total income above the basic exemption. A first-time trader declaring a loss on ITR-3 needs a proper computation, not an audit.

Should I opt for 44AD for my F&O income?

Usually not. The deemed profit of 6% scales with turnover regardless of results, you lose the ability to carry forward losses, and opting out within five years forces books and an audit under 44AD(4). File ITR-3 with the actual result instead.

Does the premium I receive on selling options count as turnover?

Not as a separate addition. Under the revised ICAI Guidance Note, the premium is captured through the profit or loss on the position. Adding it again — as the pre-2022 method did — overstates turnover.

Is intraday equity trading part of F&O turnover?

No. Intraday equity is speculative business income under Section 43(5), computed on the same absolute-difference basis but reported separately on ITR-3, with its own loss carry-forward rules.
