Tax Audit Report Date Moves to 21 October; Audit-Case Returns Due 21 November

Companies and other taxpayers whose accounts must be audited have been given 21 more days to file their tax audit report for assessment year 2026-27. The Central Board of Direct Taxes (CBDT) moved the report date from 30 September 2026 to 21 October 2026. The income tax return date for the same cases moved from 31 October to 21 November 2026. The change is set out in Circular No. 07/2026.

Section 44AB of the Income-tax Act, 1961 requires certain taxpayers to get their accounts audited, and the audit report has to be furnished by a set date. The audit report date is now 21 October 2026. Salaried individuals without an audit obligation are outside the extension, and the sections below set out who is covered, who is not, and what applies after the new dates.

Which Taxpayers the Extension Covers

TaxGuru's summary of the circular says the relief applies to the persons listed at Serial No. 2 in the table under Explanation 2 to section 139(1). That group has three kinds of taxpayer: companies; non-company assessees whose accounts must be audited under the income-tax law or another law; and partners in firms with auditable accounts, including spouses where section 5A applies.

For non-company taxpayers, the test is whether their accounts must be audited, so the type of taxpayer alone does not decide membership of the group.

India Briefing describes the group in different terms. It refers to non-company taxpayers whose accounts require audit, and to partners of firms whose accounts are required to be audited, along with specified spouses where applicable. TaxGuru ties the spouse condition to section 5A, while India Briefing refers only to specified spouses where applicable.

According to India Briefing, the announcement gives eligible taxpayers an additional 21 days to complete their audit and finalise their returns.

Who Falls Outside the Extension

The extension reaches companies and audited taxpayers, not salaried individuals without an audit obligation. Salaried taxpayers with no audit obligation are not in any of the categories TaxGuru's summary of the circular lists.

Transfer pricing cases are also excluded. TaxGuru says the extension applies only where section 92E does not apply, and India Briefing says cases under section 92E should not automatically apply the 21 November deadline. India Briefing describes section 92E as covering international transaction reporting requirements.

TaxGuru's relief article says tax experts pointed out that transfer pricing assessees fell outside the previous year's relief. It says clients with international or specified domestic transactions have report and return dates set separately.

The exclusions therefore come in two kinds: a group left out by type of taxpayer, and a group left out because the transfer pricing provisions apply to it.

The Revised Dates for Audit Reports and Returns

For covered taxpayers, the tax audit report is due 21 October 2026, up from 30 September. The return of income for the same assessment year is due 21 November 2026, up from 31 October.

Both steps move by the same 21 days, so the gap between the report date and the return date stays at 31 days, as it was before the change.

The circular is numbered 07/2026, carries the file reference F. No. 225/128/2026/ITA-II and is dated 28 September 2026.

The circular cites section 119 of the Income-tax Act, 1961 and section 536 of the Income-tax Act, 2025, along with sections 139 and 44AB of the 1961 Act.

The circular says a formal order to give effect to the extension is being issued separately.

Taken together, the two changes move each covered deadline by 21 days, and the 21 October date is the first of them.

Interest on Tax Unpaid After the New Due Date

Interest under section 234A is simple interest at 1% per month or part thereof. It runs from the day after the return due date until the return is actually filed.

Where no return is filed, the period runs until a best judgment assessment is completed, according to TaxGuru's summary of the section.

For returns filed after 21 November 2026, interest would begin on 22 November 2026. Because the rate applies to any part of a month, even a few days of the interest period are charged at the full 1%.

The interest period is tied to the return date rather than the audit report date, so 21 October does not mark the start of the interest period.

Self-assessment tax paid before the deadline carries no interest under this section, according to TaxGuru's summary.

Taken across a full year, 1% per month adds up to 12% in simple terms.

The extension reaches companies and audited taxpayers, not salaried individuals without an audit obligation.

Penalty for Missing the Audit Report Date

Section 271B applies when a taxpayer required to get accounts audited under section 44AB either does not get them audited, or does not furnish the audit report by the due date. The penalty is the lower of 0.5% of total sales, turnover or gross receipts, or ₹1.5 lakh.

The ₹1.5 lakh ceiling has applied since 1 April 2011, according to TaxGuru's summary of the section.

A Madras High Court ruling reported by TaxGuru holds that filing a return late does not by itself trigger this penalty. The penalty depends on the audit itself, meaning either that the audit was not done or that the report was not furnished in time. A missed return date and a missed report date are therefore different events under this section.

Section 273B provides a reasonable-cause defence. TaxGuru lists examples including an auditor's resignation, the death or physical inability of the partner in charge of the account, strikes or lock-outs for a long period, loss of accounts by fire or theft, and natural calamities.

An ITAT Lucknow ruling reported by TaxGuru holds that a penalty under section 271B cannot be levied simultaneously with a penalty under section 271A.

In short, section 271B is tied to the audit and its report, while the interest rule is tied to the return date.

Steps Before the 21 October Audit Report Date

The audit report is due by 21 October 2026, and section 271B applies if it is not furnished by that date.

Whether a taxpayer is in the covered group decides which dates apply. Companies, non-company assessees with auditable accounts and partners with auditable accounts are in that group, while transfer pricing cases are outside it.

TaxGuru's relief article advises confirming the category, and any linked reports, against the notification once it is published. The article points to clients with international or specified domestic transactions, whose report and return dates are set separately.

Whether a taxpayer is in the covered group, and whether section 92E applies, decide which dates it faces.
