Central Board of Direct Taxes Extends AY 2026-27 ITR Filing Deadline for Tax-Audit Cases

India’s Central Board of Direct Taxes (CBDT) has extended the deadline for filing return of income for Assessment Year (AY) 2026-27 from 31 October 2026 to 21 November 2026 for taxpayers covered by the specified tax-audit category under the Income Tax Act 1961.

The corresponding deadline for furnishing the tax audit report has also been extended from 30 September 2026 to 21 October 2026. This extension provides eligible taxpayers with an additional 21 days to complete their audit and finalise their income tax returns.

The extension applies specifically to persons covered under Serial No. 2 in Section 139(1) of the Income Tax Act, 1961. It does not extend the return filing deadlines for all taxpayers for AY 2026-27.

The update is also relevant in the context of the transition to the Income Tax Act, 2025. While the current AY 2026-27 filing cycle continues to be governed by Section 139 of the Income Tax Act 1961, the return-filing framework under the new law is contained in Section 263 of the Income Tax Act 2025 and will apply to the next tax-year filing cycle.

Latest update: AY 2026-27 return of income deadline extended by CBDT

The CBDT has extended the due date for furnishing the return of income for AY 2026-27 by 21 days for persons whose accounts are subject to audit under the Income Tax Act 1961 and who fall within the specified category under Section 139(1).

Revised Return of Income Compliance Deadlines
Compliance requirement	Earlier due date	Extended due date
Tax audit report	30 September 2026	21 October 2026
Income tax return	31 October 2026	21 November 2026

CBDT has stated that a formal order or notification giving effect to the extension will be issued separately.

The extension gives eligible taxpayers additional time to:

• Complete the tax audit
• Furnish the tax audit report
• Reconcile accounting and tax records
• Address discrepancies identified during the audit
• Finalise and file the income tax return

The extension, however, should not be interpreted as a general extension for all AY 2026-27 taxpayers.

Taxpayers covered under Section 139 of the Income Tax Act 1961

Section 139(1) establishes the general obligation to furnish an income tax return and sets different due dates according to the taxpayer’s status and reporting requirements. The provision is applicable to the following:

1. Companies
2. Non-company taxpayers whose accounts are required to be audited under the Income Tax Act or another applicable law
3. Partners of firms whose accounts are required to be audited, along with specified spouses where applicable

Taxpayers covered by the specified international transaction reporting requirements under Section 92E of the Income Tax Act 1961 fall under a separate filing category and should not automatically apply the November 21 deadline to their returns.

Implications for businesses

Businesses covered by the extension will need to ensure that the applicable tax audit is completed, the tax audit report is furnished by 21 October 2026, and the income tax return is filed by 21 November 2026.

The additional time may also facilitate the completion of audit-related reconciliations and resolution of discrepancies before the income tax return is finalised.

Taxpayers not covered by the extension

The revised deadline does not automatically apply to taxpayers falling under other categories specified under Section 139(1). The provision prescribes different filing dates depending on the taxpayer’s status and applicable reporting requirements. For example, taxpayers carrying on a business or profession whose accounts are not required to be audited have a different statutory due date.

Businesses should therefore determine the applicable filing deadline based on their specific tax-audit and reporting obligations rather than assuming that 21 November 2026 applies to all AY 2026-27 taxpayers.

CBDT has stated that a separate formal order or notification will be issued to give effect to the extension. The formal notification should be read together with the applicable provisions of Section 139 when determining the compliance deadline for a particular taxpayer.

FAQ: Return of Income under the Income Tax Act 1961 and Income Tax Act 2025

1. Is an income tax return required if income is below the basic exemption threshold?

Not necessarily. Section 139(1) specifies certain circumstances in which a person may be required to file a return even where income does not exceed the basic exemption threshold.

These circumstances include specified levels of:

• Deposits in current accounts
• Expenditure on foreign travel
• Electricity consumption
• Other prescribed conditions.

For example, the provision covers a person who deposits more than INR 10 million in one or more current accounts, incurs more than INR 200,000 on foreign travel, or incurs more than INR 100,000 on electricity consumption during the previous year.

Therefore, income below the basic exemption threshold does not, by itself, establish that no return-filing obligation exists.

2. Which provision will govern return filing under the Income Tax Act 2025?

The Income Tax Act 2025 places the corresponding return-of-income provisions under Section 263.

Section 263 provides the framework for:

1. The obligation to furnish a return
2. Applicable filing deadlines
3. Belated returns
4. Revised returns
5. Updated returns
6. Defective returns

3. When will Section 263 of the Income Tax Act 2025 apply?

Section 263 will apply under the new tax year regime beginning with tax year 2026-27.

Tax Year 2026-27 corresponds to the financial year beginning 1 April 2026. Under the new Act, the tax period is referred to as a ‘tax year’, rather than using the separate ‘financial year’ and ‘assessment year’ terminology under the 1961 Act.

Tax obligations	Income Tax Act 1961	Income Tax Act 2025
Return-filing provision	Section 139	Section 263
Tax period terminology	Assessment Year	Tax Year
Current relevance	AY 2026-27	Tax Year 2026-27 onwards
Filing obligation	Section 139(1)	Section 263
Belated return	Section 139(4)	Section 263(4)
Revised return	Section 139(5)	Section 263(5)
Updated return	Section 139(8A)	Section 263(6)
Defective return	Section 139(9)	Section 263(7)

4. How are defective returns dealt with under the two acts?

Both acts provide for the correction of defective returns.

Under the existing law, Section 139(9) deals with defective returns. Under the new law, the corresponding provision is Section 263(7).

The CBDT’s e-filing system distinguishes between the two provisions based on whether the return falls under the Income Tax Act 1961 or the Income Tax Act 2025.

5. What should taxpayers remember about the transition?

For the current AY 2026-27 filing cycle, taxpayers should apply the provisions of the Income Tax Act 1961, including Section 139.

For the next income return filing cycle relating to Tax Year 2026-27, taxpayers will move to the Income Tax Act 2025, including Section 263.
