What is the extended tax audit due date for AY 2026-27 (FY 2025-26)?

CBDT Circular No. 07/2026 dated 28 September 2026 extended the tax audit report due date from 30 September 2026 to 21 October 2026 for ordinary Section 44AB cases. The corresponding ITR filing deadline is extended to 21 November 2026.

Does the due date extension apply to all taxpayers?

No. The extension applies only to persons covered under S. No. 2 of the Table below Explanation 2 to Section 139(1) — i.e., corporate assessees, entities liable to audit under Section 44AB, partners of audited firms. Non-audit individual ITR deadline was 31 July 2026. Transfer pricing (Sec 92E) audit report due date: 31 October 2026.

What are the turnover thresholds for mandatory tax audit under Section 44AB for FY 2025-26?

Business: ₹1 Crore (standard) or ₹10 Crore if BOTH cash receipts ≤5% of total receipts AND cash payments ≤5% of total payments. Profession (Sec 44AA notified): ₹50 Lakh gross receipts. Also triggered on opt-out from Sec 44AD/44ADA with income > basic exemption.

Which forms are required for tax audit for AY 2026-27?

Form 3CA (if accounts already audited under another law like Companies Act/LLP Act) or Form 3CB (if not audited under any other law) — both accompanied by Form 3CD (Statement of Particulars). Uploaded electronically on incometax.gov.in with CA's DSC and UDIN.

What is the penalty for late filing of tax audit report?

Under Section 271B: 0.5% of total sales/turnover/gross receipts, maximum ₹1,50,000. Waivable under Section 273B if reasonable cause is established (e.g., auditor's death, natural calamity, records lost). For AY 2026-27, penalty applies if report not furnished by 21 October 2026.

Can a business with turnover below ₹1 Crore still require a tax audit?

Yes. (1) Professionals with gross receipts > ₹50 Lakh. (2) Assessee who opted out of Sec 44AD presumptive scheme within 5-year lock-in and total income > basic exemption (₹4 Lakh new regime). (3) Sec 44ADA professional declaring basic exemption. (4) Loss-making business with turnover > ₹1 Cr — audit mandatory regardless of profit/loss.

How is F&O turnover calculated for tax audit applicability?

Per ICAI Guidance Note (2025 Ed., Para 5.14(b)): F&O turnover = sum of absolute values of all favourable and unfavourable differences from each squared-off contract + option premium received on sale (if not in net profit). Not contract value. Since broker-settled trades are digital, the ₹10 Crore threshold usually applies if cash tests met.

What changes from Tax Year 2026-27 (FY 2026-27) under the new Income-tax Act, 2025?

Section 44AB renumbered to Section 63. New Form 26 replaces 3CA/3CB/3CD (Rule 47). Report due one month before ITR due date (30 Sep 2027 for audit cases). New audit trigger under Sec 58(3): any eligible business/profession declaring below presumptive rate with income > basic exemption. Penalty becomes fixed fee under Sec 428(c): ₹75,000 (≤1 month delay), ₹1,50,000 (>1 month) — no reasonable cause defence.
