Tax Audit Reports Due 21 October: What CBDT Circular 07/2026 Extends and What It Leaves Alone

The audit-report deadline for Assessment Year 2026-27 falls on Wednesday, 21 October 2026, and with Dussehra on Tuesday 20 October the working window is effectively Monday and Wednesday. The date comes from Circular No. 07/2026 (F. No. 225/128/2026/ITA-II), issued by the Central Board of Direct Taxes on 28 September 2026 and listed on the e-filing portal's news and e-campaigns page the following day. The same circular moves the return-filing date for audited assessees to 21 November 2026.

Both dates apply to the assessees at serial number 2 of the Table in Explanation 2 to section 139(1) of the Income-tax Act, 1961, the group whose return was otherwise due on 31 October: companies, persons whose accounts have to be audited under the Income-tax Act or any other law, and partners of such firms. The circular is issued under section 119 of the 1961 Act read with section 536 of the Income-tax Act, 2025, because AY 2026-27 continues to be administered under the old Act even though the new Act took effect on 1 April 2026. The transition rules for proceedings under the 1961 Act explain why that distinction will matter for the notices and assessments that follow these returns.

Why the audit date is 21 October and not a round number

The circular does not fix the audit date directly. It extends the return due date from 31 October to 21 November, and the "specified date" in clause (ii) of the Explanation to section 44AB, defined as one month before the return due date, moves with it. That mechanism has three consequences.

First, the extension reaches every report whose statutory deadline is written by reference to the section 44AB specified date, not only Form 3CA-3CD and Form 3CB-3CD. The audit reports of charitable trusts and institutions in Form 10B and Form 10BB, and the MAT report in Form 29B, are tied to the same date in the Act and therefore move to 21 October as well.

Second, the rule works only one way. An assessee who intends to file the return on, say, 5 November still had to furnish the audit report by 21 October; filing the return earlier does not bring the audit date forward, and filing it later does not push the audit date back.

Third, nothing in the circular touches assessees who have to furnish a transfer pricing report under section 92E. Their return date stays 30 November 2026 and their specified date, which also governs Form 3CEB, stays 31 October 2026. The two calendars now sit ten days apart, which is worth a separate line in the office tracker.

What has to happen on the portal before Wednesday

A tax audit report is furnished in two steps on the e-filing portal, and the second step is the one that gets missed. The chartered accountant uploads Form 3CA-3CD or Form 3CB-3CD from the ARCA login after the taxpayer has assigned the form; the taxpayer then accepts the uploaded report from their own login. The report is on record only after acceptance, so a report uploaded on 21 October and accepted on 22 October is a late report. Firms with a long client list should get the acceptance done in the same sitting as the upload, and generate the UDIN before upload so that it can be entered when the form is submitted.

Which form applies depends on whether the accounts are already audited under another law; the earlier guide to Forms 3CA, 3CB and 3CD and the filing workflow sets that out. In the last two days the clause most likely to hold up a file is still clause 44 of Form 3CD, because it needs total expenditure split by the GST status of the supplier, a break-up that rarely comes straight out of the ledger.

Missing 21 October: section 271B and the reasonable-cause defence

Failure to get the accounts audited, or to furnish the report by the specified date, attracts a penalty under section 271B of one-half per cent of the total sales, turnover or gross receipts, subject to a ceiling of ₹1,50,000. For a business with turnover of ₹6 crore the computed figure is ₹3,00,000, so the ceiling applies and the exposure is ₹1,50,000; for turnover of ₹2 crore the exposure is ₹1,00,000.

The penalty is not automatic. Section 273B bars it where the assessee proves reasonable cause, and the Assessing Officer has to give an opportunity of being heard before levying it. The defence has to be specific and documented, such as the auditor's incapacity or records seized or lost in circumstances beyond the assessee's control; a crowded October in the practitioner's office is not reasonable cause. A report furnished after 21 October but before the return is still a valid report for the return; the delay only opens the section 271B question.

The return side: 21 November and interest

For the same group, the return is due on 21 November 2026. The circular extends the due date itself rather than granting a conditional relaxation, and it says nothing about interest, so a return filed by 21 November is filed within the due date for section 234A; interest under that section begins only from 22 November. Interest under sections 234B and 234C is unaffected, because it runs on advance-tax shortfalls and not on the filing date. Self-assessment tax still has to be paid before the return is uploaded.

A return filed after 21 November is a belated return under section 139(4). For a company or firm with a business loss for the year, that is the costlier miss: section 80 allows the loss to be carried forward only if the return is filed within the section 139(1) due date, and no penalty-waiver route repairs a lost carry-forward.

Two groups get nothing from the circular. Assessees whose accounts need no audit were never in the 31 October category, and section 92E assessees keep their own dates. Firms handling both audit and transfer pricing clients should therefore run three dates this month, 21 October, 31 October and 21 November, rather than treating 21 November as a blanket return date.
