ITR-3 for AY 2026-27: Filing Guide for Traders and Professionals

Last reviewed: 25 September 2026. Position as on 25 September 2026: the non-audit due date for ITR-3 (31 August 2026) has passed, and a belated return stays open till 31 December 2026 (234F fee, 234A interest). For audit cases, the tax audit report is due by 30 September 2026 and the return by 31 October 2026; both are still open. The staggered date was not an ad-hoc extension: the Finance Act, 2026 permanently amended Section 139(1) to give ITR-3 and ITR-4 filers one month beyond the 31 July date that continues to apply to ITR-1/ITR-2. ITR-3 remains the form people get wrong most often: F&O reported as capital gains, turnover computed on contract value, audits assumed where none apply, and losses lost to a belated return. This guide covers who must file, the full AY 2026-27 due-date calendar, F&O and intraday treatment with worked numbers, the actual audit triggers, what is new in this year's form, and the regime choice for business filers.

Who must use ITR-3

ITR-3 applies to individuals and HUFs computing business or professional income on actual profits with books of account. It is also mandatory, regardless of income size, for company directors, holders of unlisted equity shares, partners reporting interest or remuneration from a firm, and anyone whose F&O or intraday trading is business income. Presumptive filers within limits use ITR-4; but a director, an unlisted shareholder, a VDA investor or anyone carrying forward a business loss must stay on ITR-3. For a form-by-form overview, see our ITR filing hub for AY 2026-27.

NRIs trading F&O in India. An NRI can trade exchange-traded derivatives funded from an NRO account through a custodial participant (CP) code, separate from the PIS route used for delivery equity. The income is business income, so the NRI files ITR-3 rather than ITR-2, gets no 87A rebate, and should reconcile any tax withheld in AIS and Form 26AS before filing. Our CA for NRIs service handles these returns.

Due-date calendar: AY 2026-27 (FY 2025-26)

Note: some commentaries still give 31 December 2026 as the revised-return deadline. The Income Tax Department's e-filing help page states that a revised return for AY 2026-27 can be filed before 31 March 2027, or before completion of assessment, whichever is earlier.

F&O and intraday: classification and turnover, with numbers

Futures and options income is non-speculative business income; intraday equity is speculative business income under Section 43(5). Both belong in ITR-3, never in the capital gains schedule. Delivery-based investments stay capital gains (for AY 2026-27: STCG under Section 111A at 20%, LTCG under Section 112A at 12.5% beyond the Rs 1.25 lakh exemption, with no mid-year rate split this year).

For the audit threshold, F&O turnover follows the ICAI guidance note: the absolute sum of profits and losses on closed trades. Premium on options sold is counted only where it is not already embedded in the net result. Contract value is irrelevant.

Losses behave very differently by bucket, and the due date decides whether they survive:

When a tax audit actually applies

The most common F&O myth is “loss = audit”. A loss by itself triggers nothing. The real triggers under Section 44AB:

Worked example. Meera has salary of Rs 18 lakh and an F&O loss of Rs 6 lakh on turnover of Rs 1.4 crore, all exchange-settled, and has never used presumptive taxation. No audit applies: turnover is within Rs 10 crore and fully digital. She keeps books under Section 44AA, filed ITR-3 by 31 August 2026, and carries the Rs 6 lakh forward for up to 8 years against future business income (it cannot be set off against salary). Had she filed belated on, say, 15 September 2026, the carry-forward would be lost and a Rs 5,000 fee under Section 234F would apply. Where audit does apply, the Form 3CB–3CD deadline is 30 September 2026 (see our Section 44AB guide), and late audit filing risks a penalty under Section 271B of 0.5% of turnover (capped at Rs 1.5 lakh).

What is new in ITR-3 for AY 2026-27

• Dedicated F&O columns: the trading account now asks for F&O turnover and income separately; broker P&L and the return must reconcile.
• No capital-gains date split: the pre/post-23-July-2024 bifurcation is gone; full-year rates of 20% (111A) and 12.5% (112A) apply.
• Partner details: interest and remuneration from firms are captured in more detail, and firms now deduct TDS at 10% on these under Section 194T (FY 2025-26 onward), so reconcile the credit in your AIS/26AS before filing.
• MSME interest: interest disallowed under the MSMED Act must be reported separately.
• Schedule AL: assets and liabilities are reportable only where total income exceeds Rs 1 crore.
• Schedule VDA continues for crypto/VDA income; ITR-1 and ITR-4 remain unavailable once VDA income exists.

Looking one year ahead: the Income-tax Act, 2025 and the Finance Act, 2026 changes (including the STT increase on derivatives from 1 April 2026: futures 0.05%, options 0.15%) affect tax year 2026-27 onwards, i.e. next year's return. The same rules move to new section numbers: tax audit to section 63 (old 44AB), the definition of speculative transaction to section 66(31) (old 43(5)), and speculation-loss set-off to section 113 (old 73). The AY 2026-27 return you file now is still governed by the 1961 Act's section numbers used here.

New regime, old regime and Form 10-IEA

The new regime is the default. For FY 2025-26 its slabs run: nil up to Rs 4 lakh, then 5% (4–8 lakh), 10% (8–12 lakh), 15% (12–16 lakh), 20% (16–20 lakh), 25% (20–24 lakh) and 30% above Rs 24 lakh, plus 4% cess. A resident with total income up to Rs 12 lakh gets a Section 87A rebate of up to Rs 60,000 (a trader with, say, Rs 9.5 lakh of normal-rate business income pays nil tax), but the rebate does not cover special-rate income such as 111A/112A capital gains. Salaried filers get the Rs 75,000 standard deduction under the new regime. The catch for ITR-3 filers: with business or professional income, opting for the old regime requires Form 10-IEA filed before the due date (31 August 2026 for non-audit cases, 31 October 2026 for audit cases), and the switch-back is effectively once-in-a-lifetime, unlike salaried taxpayers who may flip yearly. Run the break-even before filing: our old vs new regime comparison has worked examples.

Filing checklist (audit cases: before 31 October; belated: before 31 December)

• Broker P&L and contract notes for F&O/intraday; compute ICAI-method turnover and keep the working.
• Profit and loss account and balance sheet (Section 44AA books where applicable).
• Reconcile Form 26AS and AIS: TDS credits (including 194T partner-remuneration TDS), SFT entries and reported turnover should match the return.
• Bank statements, loan and interest schedules, and proofs for deductions claimed (old regime).
• Advance-tax check: shortfalls attract 234B/234C interest; presumptive filers had a single 15 March instalment.
• Decide the regime and file Form 10-IEA first if opting out with business income.
• Verify the return within 30 days of e-filing.

Common mistakes we see

• Reporting F&O in the capital gains schedule: it is business income, and the new form's F&O columns make mismatches obvious.
• Computing turnover on contract value and concluding an audit is needed when it is not.
• Assuming an F&O loss itself forces an audit: the triggers are turnover, cash percentage and the 44AD exit rule.
• Filing belated and losing an 8-year loss carry-forward that on-time filing would have preserved.
• Missing Form 10-IEA and getting locked into the default new regime despite old-regime deductions.
• Using ITR-4 while holding unlisted shares, a directorship or VDA income; those force ITR-3.
