F&O turnover calculator: tax audit and P&L
Your F&O turnover for tax, and whether a tax audit may apply.
Turnover & audit
Turnover and audit limits for the current financial year, using the current guidance.
Turnover for 2026-27 is ₹14,70,000 by the ICAI Guidance Note (Revised 2026) method. The audit limit that applies is ₹10,00,00,000, and the result is: Turnover below modeled threshold.
| Method | F&O turnover | Premium added | Total business turnover | Audit on turnover? |
|---|---|---|---|---|
| ICAI Guidance Note (Revised 2026)Current guidance | ₹14,70,000 | — | ₹14,70,000 | No |
Cash receipts and cash payments are each within 5% of the totals, so the proviso to s.63 (2025 Act) raises the limit.

What this calculator does and does not do
What this calculator does
- Works out derivatives turnover under ICAI Guidance Note (Revised 2026).
- Adds up a pasted list of each trade's profit or loss, one per line, into the wins and losses it needs.
- Applies the s.44AB (1961 Act), now s.63 (2025 Act) audit test and the s.44AD (1961 Act), now s.58 (2025 Act) presumptive test to the figure, including the condition that has nothing to do with turnover at all.
- Refuses a financial year whose published thresholds are not held here, rather than assuming this year's limits applied then.
What it does not do
- Decide every tax-audit condition from turnover alone.
- Cover business expenses, depreciation, or anything beyond the two tests on screen.
- Decide your residential status, your regime choice, your due date, or file anything.
Show the method and assumptions
The method
- Uses ICAI Guidance Note (Revised 2026).
- Adds every trade's profit or loss, ignoring the sign.
- Adds premium on options you sold only when it is outside that profit or loss.
- The yearly presumptive limits follow s.44AD (1961 Act), now s.58 (2025 Act).
What it assumes
- The limits are the ones published for the financial year you pick.
- Turnover is not margin and not contract value.

What could change this?
- Option sale premium. It is added only when it is outside the trade profit and loss.
- The financial year. Audit and presumptive thresholds change by date, and the year selects them.
- The cash-receipts condition. The higher audit limit applies only when cash receipts and payments are each within the stated share.
- Your presumptive-scheme history. Opting out within the lock-in period can require an audit regardless of turnover.
What turnover actually means here
The signs are thrown away. Say a trader made ten lakh on some trades and lost eight lakh on others. That trader has a turnover of eighteen lakh and a profit of two. A modest year, or even a losing one, can still cross a threshold. Turnover is a terrible measure of how well anybody is doing. It is not the notional value of the contracts either. A NIFTY option worth a few thousand rupees of sits on a contract worth lakhs. Turnover follows the premium and the differences, never the notional.
Contract value, profit and turnover are different figures. Contract value is quantity times the traded price. Profit keeps the sign of the price difference and multiplies it by quantity. Turnover uses the absolute difference, so the sign is removed. Compare two futures positions of 100 units each. This quantity is an input to the calculation. Check a specific contract's current separately:
| Position | Contract value | Price difference | What turnover counts |
|---|---|---|---|
| A — bought ₹1,000, sold ₹1,020 | ₹1,00,000 | +₹2,000 | ₹2,000 |
| B — bought ₹1,000, sold ₹992 | ₹1,00,000 | −₹800 | ₹800 |
| Both together | ₹2,00,000 | +₹1,200 | ₹2,800 |
₹2,00,000, ₹1,200 and ₹2,800. Only the middle one is money anybody kept. The exposure figure is the largest by a wide , and says nothing about the result. Turnover sits above the profit, because it adds the loss to the win rather than subtracting it. A broker statement that prints all three without naming them is the usual reason a first derivatives return uses the wrong number.
How to calculate F&O turnover from your broker P&L
- Download the tax P&L report for the financial year from your broker.
- Find the realised profit or loss of each F&O trade. Use the squared-off trades, not open positions.
- Add up every profit. Then add up every loss, written as a positive number.
- Add the two totals. That sum is your F&O turnover.
- Add option premium only if your report keeps it outside the trade P&L. Most broker reports do not.
The calculator can do steps 3 and 4. Open the paste box, copy the P&L column from the report, and paste it in, one trade per line. A loss needs a minus sign or brackets. Check the trade count it shows against your report.
How option premium counts
This uses ICAI Guidance Note (Revised 2026). Add every squared-off profit and loss without its sign. Add the premium on options you sold only when it is outside those figures.
Broker statements normally include that premium in each trade's profit and loss. Counting it again would make turnover too large.
The audit trap that has nothing to do with turnover
s.44AB (1961 Act), now s.63 (2025 Act) is the limit everyone knows. It requires an audit above one crore of turnover. The limit rises to ten crore when cash receipts and cash payments are each within five per cent of the totals. Because F&O settles through banking channels, the higher limit is normally the one that binds.
The one that catches people is different. Two things have to have happened. First, you opted into the presumptive scheme under s.44AD (1961 Act), now s.58 (2025 Act) in an earlier year. Second, you then declared a profit below the presumed rate. If both are true, s.44AD(4) (1961 Act), now s.58(7) (2025 Act) locks you out for five years. s.44AD(5) (1961 Act), now s.58(8) (2025 Act) then requires books and an audit. That kicks in as soon as your total income is above the basic exemption limit, whatever your turnover is. The calculator tests for this separately, and says so explicitly when it fires.
Losses, and the deadline that decides whether you keep them
F&O is non-speculative business income, declared in ITR-3. A loss can be carried forward for eight years against future non-speculative business profits. That works only if the return is filed by the due date under s.139(1) (1961 Act), now s.263(1) (2025 Act), though. Filing late does not delay the carry-forward. It forfeits it. Intraday equity is treated separately as speculative business. Its losses may only be set against speculative gains.

Open →A worked example: turnover is not what you made
Suppose four squared-off positions in a year. Two went your way, for ₹80,000 and ₹40,000. Two did not, for ₹30,000 and ₹50,000.
Your net is the ordinary arithmetic: 80,000 + 40,000 − 30,000 − 50,000 = ₹40,000. That is the profit, and broadly the thing that is taxed.
Turnover is a different question, and that number does not answer it at all. It adds the size of each difference and ignores its sign: 80,000 + 40,000 + 30,000 + 50,000 = ₹2,00,000, five times the net. With no option sale premium outside the profit and loss, that is the turnover figure.
The consequence is the reason this page exists. A year that made almost nothing can still carry a large turnover. That matters for the audit test, because the test is applied to the second number and not the first. Trade the same book twice as often for the same net result, and the turnover doubles.
Common mistakes
- Reading turnover as profit or as contract value. It is the sum of the size of every win and every loss. A busy break-even year has a large turnover, and a losing year can still cross the audit limit.
- Adding the option sale premium twice. A broker statement usually reports it inside the per-trade profit and loss. The premium-inclusive method adds it only when it is not already there.
- Reading an audit state as a decision. Whether an audit is required is a matter for a chartered accountant with the full return in front of them. The five states name the reason to take to that conversation.
F&O turnover FAQ
How is F&O turnover calculated for income tax?
It is the sum of the SIZE of every squared-off profit and every squared-off loss, ignoring the signs. A trader who made ten lakh on some trades and lost eight lakh on others has a turnover of eighteen lakh, not the two lakh they actually netted. This is why a small or even losing year can still cross an audit threshold.
How do I calculate F&O turnover from my broker P&L report?
Download the tax P&L report for the financial year from your broker. Take the realised profit or loss of every F&O trade. Add up all the profits. Add up all the losses as positive numbers. Turnover is the two totals added together. You can paste the P&L column into this calculator, one trade per line, and it does the adding for you.
Can I paste my trades from a CSV or Excel file?
Yes. Open the file, copy the column that holds each trade's profit or loss, and paste it into the calculator. A whole row works too, because the last number on each line is used. A loss needs a minus sign or brackets. Lines with no number are listed so you can check them.
How is intraday turnover calculated?
For intraday equity, turnover is worked out the same way: the size of every trade's profit or loss, added up without the sign. It is not the value of the shares bought and sold. Intraday equity is speculative business, so it is kept apart from F&O. Enter it in the calculator's extra field for intraday turnover.
Is the premium on options I sold added to turnover?
ICAI Guidance Note (Revised 2026) adds premium received on options you sold. Premium already included in the trade profit and loss is not added again. Broker statements normally include it there.
What is the tax audit limit for F&O traders?
s.44AB (1961 Act), now s.63 (2025 Act) requires an audit above one crore of turnover, and its proviso raises that to ten crore when cash receipts and cash payments are each within five per cent of the totals. F&O settles through banking channels and a recognised exchange, so for most traders the higher limit is the one that applies.
Can a tax audit be required even if my turnover is small?
Yes, and this catches people out. If you previously opted into the presumptive scheme under s.44AD (1961 Act), now s.58 (2025 Act), then declare a profit below the presumed rate, and your total income is above the basic exemption limit, s.44AD(5) (1961 Act), now s.58(8) (2025 Act) requires books and an audit regardless of turnover.
How do I carry forward an F&O loss?
F&O is non-speculative business income, declared in ITR-3. A loss may be carried forward for 8 years against future non-speculative business profits — but only if the return is filed by the due date under s.139(1) (1961 Act), now s.263(1) (2025 Act). Filing late forfeits the carry-forward entirely.
Should I use the presumptive scheme under s.44AD (1961 Act), now s.58 (2025 Act)?
That is a decision for a chartered accountant who can see your whole position. The calculator shows whether you are within the turnover limit, what profit you would have to declare, and whether the five-year lock-in under s.44AD(4) (1961 Act), now s.58(7) (2025 Act) has already been triggered.

Turnover is what frequency looks like on paper. This is what it does to an average — more attempts make an outcome more certain, not better.
