CBDT has shifted two peak-season deadlines for Assessment Year 2026–27. Tax audit reports now fall due on October 21, 2026, and income‑tax returns for audited cases move to November 21, 2026. The notice was issued on September 28, 2026, providing three weeks’ breathing room for firms and CAs.
The extension covers “persons at Serial No. 2” in the due‑date table under Section 139(1), typically assessees whose accounts require audit under Section 44AB. Non‑audit filers should not assume relief. Plan teams and client asks accordingly, since only the specified category enjoys the revised dates.

Here is the change at a glance, useful for partner briefings and client approvals. The table contrasts the original statutory timeline with the revised “specified date,” and restates the coverage language from the official notice to avoid ambiguity during scheduling and instruction emails. Keep this handy while prioritising engagements.
| Compliance | Original due date | Revised due date | Covered taxpayers |
|---|---|---|---|
| Tax audit report (Form 3CA/3CB‑3CD) | September 30, 2026 | October 21, 2026 | Persons at Serial No. 2 under Section 139(1) table |
| Income‑tax return (ITR) | October 31, 2026 | November 21, 2026 | Same category as above; audited cases only |
Freeze Form 3CD notes and benchmarking first. Reconcile AIS, Form 26AS, and general ledger variances. Complete TDS/TCS and GST‑turnover bridges. Lock partner remuneration, depreciation schedules, and ICDS adjustments. Validate MAT computations and brought‑forward losses. Map capital‑gain working papers to demat statements. Pre‑draft key disclosures to minimise last‑mile review churn.
The extension shifts filing dates; it does not rewrite liability mechanics. Interest and fee exposures continue as per law if triggers exist. Clear self‑assessment tax shortfalls early to cap daily interest. Do not defer tax payments waiting for ITR upload. Document workings, challans, and rationale for any position that changed post‑audit.
Suggested text: “CBDT has extended audit report to 21 Oct and ITR to 21 Nov for audited cases. Please approve attached 3CD notes, depreciation chart, and ledgers by tonight. Share missing proofs, loan statements, and TDS certificates. Authorise DSC use and confirm regime selection. We will schedule submission windows accordingly.”
Target filings before 8 am or after 10 pm to avoid portal peaks. Pre‑register and refresh DSCs, and test signer tokens on a dummy JSON. Batch‑upload annexures; submit returns in staggered blocks. E‑verify immediately and archive acknowledgements and DINs. Keep a fallback path using another ERI account for contingencies.
This window gives students, articles, and young CAs space to learn under supervision while teams close books. Lock 3CD and reconciliations this week, then move returns in daily sprints. Mark October 21 and November 21, 2026 on shared calendars, and secure quick client approvals to avoid last‑week traffic snarls.
