F&O Turnover & Tax-Audit
(Section 44AB) Calculator — AY 2026-27
Compute your F&O / intraday trading turnover the way the Income Tax Act requires (absolute-sum method) and find out instantly whether a Section 44AB tax audit applies — including the ₹1 cr / ₹10 cr limits, Section 44AD presumptive, and the 44AB(e) loss trap.
Read the full answer — method, rates and figures
Quick answer: F&O turnover for income tax is the absolute sum of the favourable (profit) and unfavourable (loss) differences on all squared-off trades — profits and losses are added, never netted, and it is NOT the gross contract value (ICAI Guidance Note on Tax Audit). Example: +₹8 lakh profits and −₹6 lakh losses = ₹14 lakh turnover (net ₹2 lakh is taxable income, not turnover).
For options, premium received on sale is added, unless the broker's tax P&L already includes it (avoid double counting). A tax audit under Section 44AB(a) is required if turnover exceeds ₹1 crore — raised to ₹10 crore when both cash receipts and cash payments are ≤5% (true for electronic F&O, so ₹10 crore usually applies).
Under Section 44AB(e), an audit is also mandatory below that limit if you are covered by Section 44AD(4) — you used 44AD presumptive before and now declare below the 6%/8% deemed profit (a loss counts) — and total income exceeds the basic exemption limit. Section 44AD presumptive (declare 6% deemed profit, no audit) is available up to ₹2 crore turnover, ₹3 crore where cash receipts are ≤5%.
File ITR-3 (ITR-4 if 44AD, no loss) by 31 August 2026 (non-audit) or 21 November 2026 (audit) to preserve the 8-year loss carry-forward under Section 72. Source: Income Tax Act 1961 ss. 44AB, 44AD; ICAI Guidance Note on Tax Audit.
Add up every trade that ended in a profit (positive differences only).
Add up every trade that ended in a loss — as a positive number (do not net against profits).
Is that premium already inside your broker tax P&L?
F&O settles bank ↔ broker, so this is normally digital → the ₹10 crore 44AB(a) limit.
44AD is available up to ₹3 crore turnover and removes the turnover-based audit — but locks you in for 5 years.

Your verdict & compliance checklist
- • No audit on turnover grounds — turnover ₹14.00 lakh is within your Section 44AB(a) limit ₹10 cr.
- • Form & deadline — ITR-3 (ITR-4 if 44AD with no loss). Due 31 Aug 2026 (non-audit) or 21 Nov 2026 (audit, with the audit report due by 21 Oct 2026, now passed; both extended by CBDT on 28 Sep 2026) for AY 2026-27. File on time to keep the 8-year loss carry-forward (Section 72).
- • Turnover is not income — you pay tax on the net P&L (₹2.00 lakh), not on turnover. Turnover only decides audit/44AD applicability.

How F&O turnover is calculated (worked example)
The single biggest mistake traders make is using the gross contract value (lakhs or crores of notional) as “turnover”. For income tax, turnover is the absolute sum of profit and loss differences on squared-off trades — a much smaller figure.
| Trade | Result | Adds to turnover |
|---|---|---|
| Nifty CE | +₹50,000 | ₹50,000 |
| Bank Nifty PE | −₹30,000 | ₹30,000 |
| Reliance FUT | +₹20,000 | ₹20,000 |
| Nifty PE | −₹15,000 | ₹15,000 |
| Total | Net +₹25,000 | Turnover ₹1,15,000 |
Net profit ₹25,000 is your taxable income; ₹1,15,000 is the turnover that decides audit/44AD. For options, add the premium received on sale only if it is not already inside your broker's tax P&L.
Section 44AB & 44AD thresholds (AY 2026-27)
| Provision | Limit | Effect |
|---|---|---|
| 44AB(a) — standard | ₹1 crore | Audit if turnover exceeds this |
| 44AB(a) — digital (≤5% cash) | ₹10 crore | Applies to electronic F&O |
| 44AD presumptive | ₹2 cr (₹3 cr if ≤5% cash) | 6% deemed profit, no audit; 5-yr lock-in |
| 44AB(e) — presumptive trap | below the turnover limit | Audit if 44AD(4) applies + income > basic exemption |
Now work out the tax itself
Turnover decides your audit position; it is not what you are taxed on. The F&O trading tax calculator takes your net profit or loss, applies slab rates as non-speculative business income under Section 43(5)(d), and shows the set-off and 8-year carry-forward position under Sections 71 and 72.

Start 7-day free trialHow it works
This calculator answers the two compliance questions every F&O and intraday trader faces at ITR time — “what is my trading turnover?” and “do I need a tax audit?” — using the method the Income Tax Act and the ICAI Guidance Note actually prescribe:
- Turnover = absolute sum — the sum of the absolute value of favourable (profit) and unfavourable (loss) differences on squared-off trades. Never netted; never the gross contract value.
- Options premium nuance — premium on sale of options is added, but not separately where the broker P&L already includes it (anti-double-count).
- Audit at ₹1 cr / ₹10 cr — Section 44AB(a); the ₹10 crore limit applies when cash receipts and payments are each ≤5% (true for electronic F&O).
- The 44AB(e) trap — a 44AD(4) taxpayer declaring below the deemed 6%/8% (or a loss) with income above the basic exemption is audited even below the turnover limit.
Reported via ITR-3 (or ITR-4 under 44AD). File by 31 August 2026 (non-audit) or 21 November 2026 (audit) to preserve the 8-year loss carry-forward. Sources: Income Tax Act 1961 ss. 44AB, 44AD; ICAI Guidance Note on Tax Audit under Section 44AB.
F&O tax audit due dates for AY 2026-27
If your F&O turnover needs a Section 44AB audit for FY 2025-26, the tax audit report was due by 21 October 2026 (that date has passed), and your ITR-3 is due by 21 November 2026. If the report is not yet furnished, file it now: a late report still exposes you to the Section 271B penalty, which is waived only for a reasonable cause (Section 273B). The report (Form 3CB with 3CD for an individual trader) is filed by your Chartered Accountant on the e-filing portal, and you then have to approve it from your own login. A report filed by the CA but not yet approved by you is not complete, so allow a day or two for both steps.
| What | Due, AY 2026-27 |
|---|---|
| Tax audit report (44AB) | 21 October 2026 |
| ITR-3, audit case | 21 November 2026 |
| ITR-3 / ITR-4, no audit | 31 August 2026 |
The 31 August date for non-audit business returns is new this year: Finance Act 2026 moved it from 31 July, while ITR-1 and ITR-2 stayed at 31 July. On 28 September 2026 the CBDT extended the audit-report date from 30 September to 21 October and the audit-case ITR date from 31 October to 21 November. The 21 October date has now passed; check incometax.gov.in before 21 November in case of further changes.
What happens if I miss the F&O audit deadline?
Two separate consequences, and the second usually costs a trader more:
- The Section 271B penalty. Failing to get the accounts audited or to furnish the report can attract a penalty of 0.5% of turnover or ₹1,50,000, whichever is lower. On F&O turnover of ₹2 crore that is ₹1 lakh. It is discretionary, and Section 273B says it is not levied where you show a reasonable cause for the failure.
- Losing the loss carry-forward. An F&O loss can be carried forward for 8 years only if the return is filed by the due date (Section 80 read with Section 139(3)). If your ITR-3 misses 21 November 2026 (or 31 August 2026 where no audit applies), that year's loss cannot be set off against future F&O profits.
If the calculator above says you do not need an audit, the relevant date was 31 August 2026. If you have already missed it, the return can still be filed late, but a loss in it will not carry forward. The F&O tax calculator works out the tax on the profit side.

How to use this calculator
- Enter your total ABSOLUTE profit — the sum of the profit differences on every squared-off F&O trade (add the winning trades; ignore the sign).
- Enter your total ABSOLUTE loss — the sum of the loss differences on every squared-off trade (add the losing trades as a positive number).
- If you sold options, enter the premium received on sale. Use the toggle to say whether your broker's tax P&L already includes that premium (most Zerodha/Upstox/Dhan tax P&L statements do) so it is not double-counted.
- Confirm the cash-transaction toggle. F&O is electronic, so leave 'mostly digital (≤5% cash)' on to get the ₹10 crore Section 44AB(a) limit; turn it off only if you also run a cash-heavy business on the same books.
- Read the verdict: your turnover, the applicable audit threshold, and whether a Section 44AB audit is triggered. If you have used Section 44AD before, also read the 44AB(e) note — a loss or sub-6% profit can force an audit below the turnover limit.
❓ Frequently Asked Questions
How is F&O turnover calculated for income tax?
For income-tax purposes, F&O turnover is NOT the gross contract value — it is the sum of the ABSOLUTE value of favourable (profit) and unfavourable (loss) differences on every squared-off trade (ICAI Guidance Note on Tax Audit). Profits and losses are added, never netted.
Example: profitable trades total +₹8,00,000 and loss-making trades total −₹6,00,000, so turnover = ₹8,00,000 + ₹6,00,000 = ₹14,00,000 (the net is only ₹2,00,000, but that is taxable income, not turnover). For options, the premium received on the sale of options is added to turnover — however the ICAI's revised guidance drops this separate add-back where your broker's tax P&L has already included the option-sale premium in the per-trade difference, to avoid double counting.
Use the 'premium already in broker P&L' toggle so you count it once.
Do I need a tax audit for F&O trading (Section 44AB)?
A tax audit under Section 44AB(a) is required if your F&O turnover (absolute-sum method) exceeds ₹1 crore — raised to ₹10 crore when both your aggregate cash receipts and cash payments are each 5% or less of the total (Finance Act 2020). Because F&O is settled electronically through the broker, almost all traders meet the 5% cash test and the ₹10 crore threshold applies.
Separately, under Section 44AB(e), an audit can be required even below that turnover: if you are covered by Section 44AD(4) — you previously opted into 44AD presumptive and now declare profit below the 6%/8% deemed rate (a loss counts) — and your total income exceeds the basic exemption limit, an audit is mandatory. This is the trap that catches retail traders with large losses who want to carry them forward.
What is the audit turnover limit — ₹1 crore or ₹10 crore?
Both exist. The base Section 44AB(a) limit is ₹1 crore.
It is raised to ₹10 crore only when BOTH aggregate cash receipts AND aggregate cash payments are 5% or less of the respective totals. F&O trading is 100% electronic (money moves bank ↔ broker), so a pure F&O trader almost always satisfies the 5% cash test and gets the ₹10 crore limit.
If you also run a cash-heavy business whose accounts are combined, you could fall back to the ₹1 crore limit — check the cash test for your whole proprietorship, not just trading.
Can I use Section 44AD presumptive taxation to avoid the audit?
If your turnover is ≤ ₹2 crore (raised to ₹3 crore where cash receipts are ≤ 5%), you can opt for Section 44AD presumptive taxation: declare 6% of turnover as deemed profit (8% for non-digital receipts; F&O is digital, so 6%), skip detailed books and skip the audit. Caveats: (1) you cannot then claim actual expenses; (2) it locks you in for 5 consecutive years (Section 44AD(4)) — exit before that and you are barred for the next 5 years and can trigger the 44AB(e) audit; (3) the ₹10 crore 44AB(a) limit does not apply to a 44AD taxpayer — you are capped at the ₹2/₹3 crore 44AD limit.
If your real profit is below 6% of turnover, 44AD makes you pay tax on more than you earned — run both routes before electing.
Is a tax audit required if I only made an F&O loss?
A loss does not by itself force an audit on turnover grounds — if your turnover is under the ₹1 crore / ₹10 crore Section 44AB(a) limit, 44AB(a) does not apply. BUT a loss is, by definition, profit below the 6%/8% presumptive rate, so if you are covered by Section 44AD(4) (you had opted into 44AD earlier) and your total income exceeds the basic exemption limit, Section 44AB(e) makes the audit mandatory.
If you have never used 44AD, 44AB(e) does not apply and you can file ITR-3 with the loss without an audit — just file by the due date (31 August 2026 for non-audit ITR-3 in AY 2026-27) to carry the loss forward 8 years under Section 72.
Which ITR form and due date apply to F&O traders in AY 2026-27?
F&O income is business income, so you file ITR-3 (ITR-4 only if you opt for 44AD presumptive AND have no loss). For AY 2026-27 (FY 2025-26) the due dates are staggered: 31 August 2026 for non-audit ITR-3 filers (business/profession without audit), and 21 November 2026 where a Section 44AB audit applies, with the tax audit report itself due by 21 October 2026 (CBDT extended both dates, from 31 October and 30 September, on 28 September 2026).
File on time — a late return forfeits the right to carry the F&O loss forward 8 years (Section 72 read with Section 80). These are the statutory dates; always confirm on incometax.gov.in in case of an extension.
What is the tax audit due date for F&O traders in AY 2026-27, and what if I miss it?
For FY 2025-26 (AY 2026-27), the Section 44AB tax audit report (Form 3CB with 3CD for an individual trader) was due by 21 October 2026 (CBDT extended it from 30 September on 28 September 2026), and that date has now passed with no further extension. A report not yet furnished can still be filed late: your Chartered Accountant files it on the e-filing portal and you then approve it from your own login, so do both steps as soon as you can.
The ITR-3 for an audit case is due by 21 November 2026 (extended from 31 October). The penalty for not getting the audit done or not furnishing the report, under Section 271B, is 0.5% of turnover or ₹1,50,000, whichever is lower, and it is discretionary: it is not levied if you show a reasonable cause (Section 273B).
