CBDT Circular 7/2026: audit-case ITR due date for AY 2026-27 moved to 21 November 2026, tax audit report to 21 October

The Central Board of Direct Taxes (CBDT) has given audit-case taxpayers 21 more days to file their income tax return for Assessment Year 2026-27. CBDT Circular No. 07/2026, dated 28 September 2026 (F. No. 225/128/2026/ITA-II), moves the return due date for this category from 31 October 2026 to 21 November 2026. As a consequence, the specified date for the tax audit report under section 44AB moved to 21 October 2026, which the e-filing portal notice describes as an extension from 30 September 2026.

As of 3 November 2026, the audit report date of 21 October 2026 has already passed, and 18 days remain until the new return due date of 21 November 2026. This explainer sets out what the circular says, who it covers, how the dates fit together, and the mistakes that most often turn a deadline extension into a notice.

What the Section Says

The circular is issued under section 119 of the Income-tax Act, 1961, which lets the CBDT issue orders, instructions and directions to income-tax authorities. It is read with section 536 of the Income-tax Act, 2025. The 1961 Act still governs this return because AY 2026-27 relates to income of Financial Year 2025-26 (the previous year), so every section number below refers to the 1961 Act. The full text of the Act is on India Code.

Three provisions interlock:

1. Section 139(1), Explanation 2 sets the "due date" for filing returns through a Table. The circular extends the date only for persons referred to in Sl. No. 2 of that Table: the audit-case category.
2. Section 44AB requires certain persons to get their accounts audited and to furnish the audit report by the "specified date".
3. Clause (ii) of the Explanation to section 44AB defines that specified date by reference to the return due date under section 139(1). When the return date moves, the audit report date moves with it, which is why the report date shifted to 21 October 2026 without a separate order.

The circular applies only to persons in Sl. No. 2 of the Table. It does not change the due date for any other category. A salaried individual or a non-audit taxpayer whose own due date has already passed gains nothing from Circular 07/2026. The circular identifies the class by its serial number rather than by description, so read the Table below Explanation 2 to section 139(1) to confirm where you fall before relying on 21 November 2026.

Worked Example

Consider a sole proprietor, Ms A, whose business accounts for FY 2025-26 had to be audited under section 44AB. Her business income for the year, after expenses, is Rs 30,00,000, she has no other income, and she files under the new tax regime. Her CA uploaded the audit report on 18 October 2026, three days before the extended specified date of 21 October 2026.

Step 1: the dates that apply to her.

Step 2: her tax under the FY 2025-26 new-regime slabs. The rebate under section 87A (up to Rs 60,000 where income does not exceed Rs 12,00,000) does not apply, because her income is Rs 30,00,000. Surcharge does not apply because her income is below Rs 50 lakh.

Step 3: what she must do before 21 November 2026. She deducts any TDS and advance tax already paid from the Rs 4,99,200 liability, pays the balance as self-assessment tax, and then files her return on the e-filing portal. If her advance tax for FY 2025-26 fell short, the interest consequences run under sections 234B and 234C, which are separate from the due date. You can rerun her numbers, or your own, on the income tax calculator and check the regime choice on the old vs new regime calculator.

Step 4: the counterfactual. Had her CA uploaded the audit report on 25 October 2026, four days after the 21 October 2026 specified date, the 21-day extension of the return date would not cure that delay. Section 44AB compliance is judged against its own specified date, and failure to furnish the audit report is dealt with under section 271B. The return extension and the audit report date are linked in how they are calculated, but they are tested separately.

Common Mistakes

These are the errors that most often surface when returns filed around an extended due date are processed or scrutinised.

1. Assuming the extension covers everyone. Circular 07/2026 extends the date only for Sl. No. 2 of the Table under Explanation 2 to section 139(1). A non-audit taxpayer who reads "ITR due date extended to 21 November 2026" in a headline and files late is filing a belated return under section 139(4), with the consequences that follow, including the fee under section 234F.

2. Treating the audit report and the return as one deadline. The audit report date was 21 October 2026; the return date is 21 November 2026. The 31-day gap between them is deliberate. An audit report uploaded after 21 October 2026 is late even if the return goes in on 20 November 2026.

3. Assuming interest under section 234A automatically follows the new date. Section 234A charges interest for a return furnished after the due date. The briefing on Circular 07/2026 describes only the extension of the due date and the consequential audit report date; it says nothing about how section 234A interest is computed. Read the circular text on incometax.gov.in for any proviso on interest before assuming none is payable for the period between 31 October 2026 and filing.

4. Citing the wrong Act. Because the Income-tax Act, 2025 is now in force, some taxpayers and preparers are quoting its section numbers for AY 2026-27 filings. The circular itself relies on section 119 of the 1961 Act, read with section 536 of the 2025 Act, and refers to section 139(1) and section 44AB of the 1961 Act. For income of FY 2025-26, the 1961 Act is the reference.

5. Leaving self-assessment tax to the last day. A return showing tax payable is defective if the tax has not been paid. On Ms A's numbers, an unpaid balance on a Rs 4,99,200 liability has to be cleared before the return is filed on or before 21 November 2026, not on the evening of the due date when bank and portal traffic peaks.

6. Ignoring the mismatch check. Before filing, reconcile income and TDS with your Form 26AS and Annual Information Statement. Differences between the audited accounts, Form 26AS and the AIS are a frequent trigger for adjustment under section 143(1).

FAQ

Who gets the extended ITR due date of 21 November 2026?

Only persons referred to in Sl. No. 2 of the Table below Explanation 2 to section 139(1) of the Income-tax Act, 1961, which is the audit-case category. CBDT Circular No. 07/2026, dated 28 September 2026, says it does not change due dates for any other category.

What was the original due date for these taxpayers?

The original due date for the Sl. No. 2 category for AY 2026-27 was 31 October 2026. Circular 07/2026 moves it by 21 days to 21 November 2026.

Has the tax audit report deadline also been extended?

Yes. Under clause (ii) of the Explanation to section 44AB, the specified date for the audit report is tied to the return due date, so it moved to 21 October 2026. The e-filing portal notice describes this as an extension from 30 September 2026. That date has now passed.

Does the extension apply to salaried taxpayers?

No. The circular applies only to the Sl. No. 2 category. A salaried individual whose accounts are not required to be audited is not covered by Circular 07/2026, and a return filed after their own due date is a belated return under section 139(4).

Why does the circular refer to the 1961 Act and not the Income-tax Act, 2025?

AY 2026-27 relates to income of FY 2025-26, which is governed by the Income-tax Act, 1961. The circular is issued under section 119 of the 1961 Act read with section 536 of the 2025 Act.

Will I owe interest under section 234A if I file on 20 November 2026?

The summary of Circular 07/2026 available to us addresses only the due date and the audit report date, not section 234A interest. Check the circular text on incometax.gov.in for any proviso on interest. Separately, shortfalls in advance tax for FY 2025-26 attract interest under sections 234B and 234C regardless of the filing date; the advance tax calculator shows how instalments are tested.

Where can I read the circular?

The circular is published on the Income Tax Department's portal at incometax.gov.in as Circular No. 07/2026, F. No. 225/128/2026/ITA-II, dated 28 September 2026, signed by Dr. Indu Bala, Deputy Secretary.
