By Vaisakh Vigneswaran, M.Com · Published 28 Sept 2026 · Updated 28 Sept 2026

CBDT has moved the tax audit report date for AY 2026-27 to 21 October 2026 and the ITR date for audit cases to 21 November 2026. Here is who is covered and what stays the same.

What CBDT announced

On 28 September 2026, the Central Board of Direct Taxes (CBDT) extended two due dates for Assessment Year 2026-27, which relates to the financial year 2025-26.

The last date to furnish the tax audit report moves from 30 September 2026 to 21 October 2026. The last date to file the income tax return for audit cases moves from 31 October 2026 to 21 November 2026. That is 21 extra days for each step.

The decision was announced through a press release. CBDT said a formal order or notification giving effect to it will be issued separately. Until that document is published, the exact wording is not available. Keep a copy of the formal order in your compliance file once it is out, because that is the document that will apply.

  • Tax audit report: 30 September 2026 moved to 21 October 2026
  • ITR for audit cases: 31 October 2026 moved to 21 November 2026
  • Assessment Year: 2026-27 (financial year 2025-26)
  • Formal order or notification: to be issued separately

Who is covered

The extension applies to persons listed at serial number 2 of the table below Explanation 2 to section 139(1) of the Income-tax Act, 1961. In simple terms, this group is:

First, every company. Second, any taxpayer other than a company whose accounts must be audited under the Income-tax Act or under any other law, such as a proprietorship or firm that crosses the section 44AB limits. Third, a partner of a firm whose accounts must be audited.

The tax audit report covered here is the one under section 44AB, filed in Form 3CA or Form 3CB along with Form 3CD.

Note that FY 2025-26 returns are still filed under the Income-tax Act, 1961, even though the Income-tax Act, 2025 came into force on 1 April 2026. The old forms and section numbers apply for this year. If your business files any other audit report whose due date is linked to the same timeline, check the formal order before relying on the new date.

What is not extended

The extension is narrow. It does not change every income tax date, so read it carefully.

Transfer pricing cases are not covered. Businesses that must file a report under section 92E in Form 3CEB should continue to work to their existing dates, which are 31 October 2026 for the report and 30 November 2026 for the return, unless the formal order says otherwise.

The announcement also does not mention any change for taxpayers who do not need an audit. If they miss their own due date, the return has to be filed as a belated return with a late fee under section 234F.

Other obligations run on their own calendar. Advance tax instalments, TDS and TCS deposits and returns, and the last date for belated or revised returns are not part of this announcement.

Finally, the extension is about filing. It does not say anything about interest under section 234A on unpaid tax. Wait for the formal order before assuming any relief on interest.

  • Transfer pricing cases (Form 3CEB under section 92E)
  • Returns of taxpayers who do not need an audit
  • Advance tax, TDS and TCS due dates
  • Belated and revised return dates
  • No stated relief on interest under section 234A

Missing the new dates

The new dates are the final dates for this year unless CBDT says otherwise. Missing them has a cost.

If the tax audit report is not furnished by 21 October 2026, penalty under section 271B can apply. The penalty is 0.5 percent of turnover or gross receipts, with a maximum of ₹1.5 lakh, unless you can show a reasonable cause for the delay.

If the return is not filed by 21 November 2026, it becomes a belated return. A late fee under section 234F applies, interest on any unpaid tax continues to run, and some benefits, such as carrying forward certain business losses, can be lost when a return is late.

The practical point is simple. Treat 21 October and 21 November as hard deadlines, and aim to finish well before them. Portal load is usually heavy in the last few days before any due date.

How to use the extra 21 days

The extra time helps only if it is used well. Most audit delays come from records that are not ready, not from the audit itself. A short plan for the next three weeks can make the difference.

Start by closing the books for FY 2025-26 if any entries are still pending. Then work through the items that usually hold up Form 3CD, such as reconciliations and supporting schedules. Share queries with your auditor early so there is time to resolve them.

  • Finalise the trial balance and book all year-end entries
  • Reconcile Form 26AS and AIS with your books
  • Match GST returns with sales and purchase ledgers
  • Prepare schedules for fixed assets, loans and related party transactions
  • Check TDS deducted and deposited against expense heads
  • Work out self-assessment tax and pay it without waiting for the ITR

Looking ahead and where FBS fits

This is the last year of tax audits under section 44AB and Forms 3CA, 3CB and 3CD. From tax year 2026-27, the tax audit falls under section 63 of the Income-tax Act, 2025, and the report is to be furnished in Form 26. It is worth reviewing your record keeping now, so next year's audit under the new form starts on a clean base.

This announcement covers income tax dates only. Company filings with the Registrar of Companies, such as AOC-4 and MGT-7, run under the Companies Act and follow the Ministry of Corporate Affairs' own dates. Track them separately.

At FBS Advisory, we prepare books, reconciliations and audit schedules for businesses in Kerala and across India. Tax audit reports are signed by our partner Chartered Accountant firm. If you need help getting your records audit ready before 21 October, reach out to our team.
