Will I Get an Income-Tax Notice for F&O Trading? The 2026 Guide

By FnOTax India Editorial Board · Updated 2026-05-30 · F&O Taxation Source verified

ICAI Guidance Note on Tax Audit (Revised 2025) — turnover formula update. The ICAI Direct Taxes Committee’s Tenth Edition (Revised 2025) of the Guidance Note on Tax Audit under Section 44AB updates the F&O turnover method. For tax audits of FY 2025-26 (AY 2026-27) onwards, the turnover formula is:

  1. Sum of favourable and unfavourable differences on squared-off trades; plus
  2. Premium received on sale of options — with anti-double-count proviso: if your broker P&L already nets the option-sale premium into the per-trade profit/loss, do not add the premium separately.
  3. Differences on reverse trades also count.
  4. Open positions at year-end are picked up when squared off.
  5. Delivery-settled derivatives use the trade-vs-settlement price difference; if you held the underlying as stock-in-trade, the entire sale value is business turnover.

For AY 2026-27 onward, use the Revised 2025 edition. Earlier assessment years should be checked against the ICAI guidance applicable to that year.

Short answer

Notice risk is highest for: filing ITR-1/2 instead of ITR-3, AIS-versus-return mismatches, claimed loss carry-forward without timely return, and missed s.44AB / s.63 audit requirements. Clean ITR-3 filing with a reconciliation memo materially reduces risk.

Income-tax notices to F&O traders typically fall into a small number of categories: defective-return notices under 1961 Act s.139(9) / 2025 Act successor; intimation adjustments under 1961 Act s.143(1) / 2025 Act s.270; scrutiny notices under s.143(2); and reassessment notices under s.148/148A. The CBDT FAQs on the 2025 Act transition confirm that procedural communications issued before 1 Apr 2026 continue to be governed by the 1961 Act, and notices issued from 1 Apr 2026 use the 2025 Act framework.

The first thing to verify

Do not respond to a notice from memory. Verify it on the e-Filing portal under e-Proceedings or Pending Actions. A genuine notice has a Document Identification Number (DIN) and is visible inside your portal login. Notices received only by email or SMS without a DIN-validated portal entry should not be treated as actionable until verified.

Most common F&O notice patterns

  1. AIS mismatch query / 143(1) intimation: the system flagged a difference between AIS/TIS feeds and the return. Pull the AIS, the broker tax P&L, and the return. The reconciliation note showing how F&O turnover was computed under the ICAI Revised 2025 method usually resolves this.
  2. Defective-return notice (s.139(9)): common when F&O business income is reported in ITR-2 instead of ITR-3, or when business schedules are inconsistent. Fix is to file a corrected return within the time allowed.
  3. Audit-without-report notice: raised when the system believes a s.44AB audit was required and not furnished. Defence is the source-verified audit-applicability working: ICAI turnover, s.44AB(a) cash-condition test, and any s.44AD(4) opt-out history.
  4. Reassessment notice (s.148 / s.148A): governed by separate timelines and reasons. Engage a qualified professional before replying.

Notice-risk reduction checklist

File ITR-3 when business income is involved. Compute ICAI turnover correctly. Preserve broker tax P&L, trade-wise report, contract notes, ledger, bank statement. Test s.44AB / s.63 audit applicability. File within the s.139(1) / s.263(1) due date if loss carry-forward is needed.

What changes under the 2025 Act for notice exposure

For the 1961 Act period (AY 2025-26 and earlier), the audit-failure sanction is s.271B (penalty: 0.5% of turnover or ₹1,50,000, whichever is less; s.273B reasonable-cause defence available). For the 2025 Act period (AY 2026-27 onwards, as substituted by Finance Act 2026), the audit-failure sanction is s.428(c) — a flat fee of ₹75,000 (delay up to one month) or ₹1,50,000 thereafter, with no 0.5%-of-turnover cap and no carried-over reasonable-cause defence.

This is why the same fact pattern can attract a smaller exposure under the 1961 Act and a larger flat exposure under the 2025 Act once 1 Apr 2026 is crossed. Calendar matters; do not transplant 1961-Act language onto a 2025-Act notice or vice versa.

What to preserve before replying

Broker tax P&L, trade-wise report, contract notes, ledger, bank statement, AIS/TIS download, ITR-V (and audit report where applicable), and the source-verified turnover/audit working. A reply that quotes the statute correctly and attaches a clean reconciliation is materially stronger than a one-line denial.

Dual-citation framing (AY 2025-26 vs AY 2026-27)

This guide cites two statutes side-by-side because India is mid-transition.

  • AY 2025-26 (TY 2024-25) and earlier: the Income-tax Act, 1961 applies. Returns filed in 2025 follow 1961-Act section numbers (43(5), 44AA, 44AB, 44AD, 71, 72, 73, 74, 80, 139, 143, 271B).
  • AY 2026-27 (TY 2026-27) onwards: the Income-tax Act, 2025 (Act No. 30 of 2025, assented 21 Aug 2025, commenced 1 Apr 2026 per s.1(3)) applies, with the 1961 Act repealed by s.536. Successor section numbers are 2(31), 2(33), 58, 62, 63, 110, 111, 112, 113, 117, 263, 270, 408, 428. Forms move from 3CA/3CB/3CD to Form 26 under the Income-tax (No. 2) Rules, 2026 (CBDT Notification 22/2026, in force 1 Apr 2026).

When a calendar date is not pinned to a CBDT circular below, treat the date as indicative and reconcile with the e-Filing utility before relying on it.

FAQ

1. Will I get a notice automatically for filing F&O? No. Notices typically follow mismatches or missed compliance, not the existence of F&O activity.

2. Does a small loss attract a notice? Not by itself. The more common trigger is form-choice errors or AIS mismatches.

3. Does the 2025 Act change notice exposure? Procedural notice mechanics carry over; the audit-failure sanction changes from s.271B penalty to s.428(c) flat fee from 1 Apr 2026.
