Income Tax Return Filing Due Dates for AY 2026-27

The Income Tax Return filing due date for AY 2026-27 depends on the taxpayer’s circumstances, including whether the taxpayer is required to get accounts audited and whether the case is covered by transfer pricing provisions.

AY 2026-27 is also an important transition year because the Income-tax Act, 2025 has come into force from 1 April 2026. However, this does not mean that the return for AY 2026-27 is governed by the new Act.

The return for AY 2026-27 relates to income earned during FY 2025-26. According to the Income Tax Department, such returns continue to be governed by the Income-tax Act, 1961, even though the return may be filed after the new Income-tax Act, 2025 has come into force.

In this article, we explain the Income Tax Return filing due dates for AY 2026-27, who needs to file by each deadline, what happens if the due date is missed, and how the transition to the new Income-tax Act affects the filing of the return.

Income Tax Return Filing Due Dates for AY 2026-27: Quick Overview

The applicable Income Tax Return filing due date depends on the taxpayer and the nature of the return.

Taxpayer / Case	Due Date for AY 2026-27
Individuals and other taxpayers covered by the regular non-audit due date	31 July 2026
Certain non-audit business or profession cases	31 August 2026
Taxpayers whose accounts are required to be audited	31 October 2026
Cases covered by applicable transfer pricing provisions	30 November 2026

The exact due date should always be determined based on the taxpayer’s circumstances rather than simply by looking at the ITR form being filed.

For example, the Income Tax Department’s current AY 2026-27 guidance confirms 31 August 2026 as the due date for ITR-4 in the relevant cases. The Department’s partnership-firm guidance also distinguishes between non-audit business cases, tax audit cases, and transfer pricing cases.

Income Tax Return Filing Due Dates for AY 2026-27: Who Has to File the Income Tax Return by 31 July 2026?

Income Tax Return Filing Due Dates for AY 2026-27, 31 July 2026 is the regular due date applicable to taxpayers falling within the non-audit category for whom the extended business or profession deadline does not apply.

This can include individuals and other eligible taxpayers whose income does not fall within the categories attracting the later due dates.

For example, an individual whose income consists of:

Salary or pension,
Interest income,
Rental income,
Capital gains, or
Other eligible sources of income,

may generally fall within the regular due-date category, subject to the specific provisions applicable to that taxpayer.

The Income Tax Department has also issued reminders specifically referring to 31 July 2026 as the due date for AY 2026-27 returns.

However, taxpayers should not determine their due date based solely on the source of income. Other circumstances, such as partnership status or business/profession-related provisions, may affect the applicable deadline.

Income Tax Return Filing Due Dates for AY 2026-27: Who Has to File the Income Tax Return by 31 August 2026?

One of the important changes taxpayers need to be aware of for AY 2026-27 is the 31 August 2026 due date applicable to relevant non-audit business or profession cases.

This is particularly important because taxpayers may be accustomed to seeing 31 July as the standard deadline for individuals and 31 October for audit cases.

The Income Tax Department’s current guidance for AY 2026-27 confirms 31 August 2026 as the due date for ITR-4 in the relevant cases. The Department’s partnership-firm guidance also specifies 31 August for a firm having income from business or profession where tax audit is not required.

The 31 August category can therefore be relevant for taxpayers carrying on business or profession where the accounts are not required to be audited, subject to the applicable filing provisions.

This distinction is important because the due date is not simply determined by whether the taxpayer files ITR-3 or ITR-4. The taxpayer’s actual circumstances and the statutory conditions applicable to the return must be considered.

Income Tax Return Filing Due Dates for AY 2026-27: Who Has to File the Income Tax Return by 31 October 2026?

The 31 October 2026 deadline generally applies to cases where the taxpayer’s accounts are required to be audited under the applicable provisions.

This may include certain businesses and professions that cross the applicable audit thresholds or otherwise fall within the tax audit provisions.

The tax audit requirement and the ITR filing requirement are related but separate compliance obligations.

A taxpayer in an audit case may therefore have to complete:

The tax audit as required under the Income-tax Act, 1961.
The filing of the applicable audit report within the prescribed deadline.
The filing of the Income Tax Return by the applicable ITR due date.

The exact applicability of tax audit should be determined based on the taxpayer’s business or professional activities and the relevant provisions of the law.

Income Tax Return Filing Due Dates for AY 2026-27: Who Has to File the Income Tax Return by 30 November 2026?

The 30 November 2026 deadline applies to cases covered by the applicable transfer pricing provisions.

These cases generally involve taxpayers who are required to comply with the transfer pricing documentation and reporting requirements applicable to specified international transactions or specified domestic transactions.

The extended deadline is intended to provide additional time for taxpayers who have more complex compliance requirements involving transfer pricing.

Taxpayers falling within this category should also consider the separate deadlines applicable to transfer pricing reports and related compliance forms.

What Is the Difference Between FY 2025-26, AY 2026-27 and Tax Year 2026-27?

The transition to the new Income-tax Act can make tax terminology confusing.

For the return currently being filed:

FY 2025-26

This is the financial year during which the income was earned, from 1 April 2025 to 31 March 2026.

AY 2026-27

This is the assessment year for which the return of income earned during FY 2025-26 is filed.

Tax Year 2026-27

This is the new terminology under the Income-tax Act, 2025 and relates to the period beginning 1 April 2026. Taxpayers do not have to file two returns for the transition period. The return for income earned during FY 2025-26 is filed as AY 2026-27, while the return for Tax Year 2026-27 will become due after that tax year ends.

Which Income Tax Return Filing Due Date Applies to You?

The easiest way to determine your Income Tax Return filing due date is to first identify your compliance category.

If you are an individual with no audit requirement and do not fall under a category attracting an extended deadline:

Your due date may be 31 July 2026.

If you are carrying on business or profession and the applicable provisions place you in the non-audit business/profession category:

Your due date may be 31 August 2026.

If your accounts are required to be audited:

Your due date is generally 31 October 2026.

If your case is covered by applicable transfer pricing provisions:

Your due date is generally 30 November 2026.

However, these dates should be treated as a starting point for determining the correct deadline. Taxpayers should consider their individual circumstances and the specific provisions applicable to them.

In the next part, we will look more closely at the 31 July and 31 August categories, including practical situations where taxpayers may be unsure which deadline applies to them.

31 July 2026 or 31 August 2026: Which Due Date Applies?

One of the most important questions for taxpayers filing their Income Tax Return for AY 2026-27 is whether the applicable due date is 31 July 2026 or 31 August 2026.

This distinction is particularly important because the due date for certain non-audit business cases has changed for AY 2026-27.

The traditional approach of treating 31 July as the due date for all individuals and 31 August as the date only for certain business taxpayers is no longer sufficient. Taxpayers need to consider the nature of their income and their specific status under the applicable provisions.

For AY 2026-27, the broad distinction is:

31 July 2026: Generally applicable to taxpayers falling within the regular category where the extended business or profession due date does not apply.

31 August 2026: Applicable to relevant non-audit business or profession cases and other categories covered by the applicable provisions.

The Income Tax Department’s Budget 2026 FAQs specifically clarify that the due date for non-audit business cases and trusts has been extended from 31 July to 31 August. The FAQ also confirms that the corresponding amendment to the Income-tax Act, 1961 applies to AY 2026-27, making 31 August 2026 the applicable due date for the relevant non-audit cases for this assessment year.

Income Tax Return Filing Due Dates for AY 2026-27:: 31 July 2026 applicable to whom?

The 31 July 2026 deadline generally applies to taxpayers who fall within the regular category and do not fall under the provisions that prescribe a later due date.

This may include individuals whose income is from sources such as:

Salary or pension.
Interest income.
Rental income.
Capital gains.
Other sources of income.

However, the source of income alone does not always determine the due date.

A taxpayer should also consider whether they are:

Carrying on a business or profession.
A partner in a partnership firm.
Subject to tax audit requirements.
Covered by transfer pricing provisions.
Otherwise covered by a category with a different statutory due date.

Therefore, simply having interest income or capital gains does not automatically mean that 31 July is always the applicable deadline.

The official Budget 2026 FAQ explains that the due date for non-audit business cases and trusts was extended from 31 July to 31 August. It further clarifies that the corresponding amendment to the Income-tax Act, 1961 applies to AY 2026-27, which means that the 31 August 2026 deadline applies to the relevant non-audit business cases for the return being filed now.

What Is the Due Date for a Partner in a Partnership Firm?

The due date for a partner in a partnership firm can be different from that of an individual who has no connection with a business or profession.

For AY 2026-27, the official Income Tax Department’s due-date guidance specifically identifies a partner of a firm whose accounts are not required to be audited as falling within the 31 August category, provided the applicable transfer pricing provisions do not apply.

Where the firm’s accounts are required to be audited, the applicable due date for the relevant partner can move to 31 October 2026. Where the case is covered by applicable transfer pricing provisions, the due date can be 30 November 2026.

This means that the status of being a partner can be relevant when determining the due date.

What Is the Due Date for a Partner of a Firm Subject to Tax Audit?

Where a partner is covered by the applicable provisions and the firm’s accounts are required to be audited, the due date generally falls under the audit category.

For AY 2026-27, the relevant due date is generally:

31 October 2026

This is different from the 31 August deadline applicable to a partner of a firm whose accounts are not required to be audited.

The tax audit status of the firm can therefore have an impact on the partner’s own ITR filing deadline.

The partner should also consider whether the firm or the partner is covered by applicable transfer pricing provisions, which can result in a 30 November deadline.

Does a Partnership Firm Have to File Its Own Income Tax Return?

Yes. A partnership firm is required to file its own Income Tax Return in respect of its income or loss. The firm’s due date and the partner’s due date are related in some situations but should not be assumed to be identical in every case.

The Income Tax Department’s current guidance lists the following broad due dates for partnership firms:

31 July 2026 in other cases.
31 August 2026 where the firm has income from business or profession and tax audit is not required.
31 October 2026 where tax audit is required.
30 November 2026 where applicable transfer pricing requirements apply.

Income Tax Return Filing Due Dates for AY 2026-27: What Is the Due Date for Tax Audit Cases?

Where the taxpayer’s accounts are required to be audited under the applicable provisions, the ITR due date is generally 31 October 2026 for AY 2026-27, assuming the case is not covered by the transfer pricing provisions that attract the 30 November deadline.

The taxpayer should also ensure that the relevant tax audit report is furnished within the prescribed timeline.

It is important to remember that the tax audit report deadline and the ITR filing deadline are separate compliance requirements, even though they are closely connected.

A taxpayer should therefore plan for both compliances rather than waiting until the ITR filing deadline.

Income Tax Return Filing Due Dates for AY 2026-27: What Is the Due Date for Transfer Pricing Cases?

Where the taxpayer is required to furnish a report under the applicable transfer pricing provisions, the Income Tax Return filing deadline is generally 30 November 2026 for AY 2026-27.

Transfer pricing cases typically involve additional compliance requirements, including the preparation of transfer pricing documentation and the filing of the applicable report.

The extended deadline is intended to accommodate the additional compliance involved in these cases.

Taxpayers should, however, review the specific provisions applicable to their transactions and ensure that all related compliance requirements are completed within their respective deadlines.

Which Due Date Should You Check First?

If you are unsure about your Income Tax Return filing due date for AY 2026-27, the following sequence can help:

Step 1: Are your accounts required to be audited?

If yes, the due date is generally 31 October 2026, subject to transfer pricing provisions.

Step 2: Are you covered by applicable transfer pricing provisions?

If yes, the due date is generally 30 November 2026.

Step 3: Do you have income from business or profession but are not required to get your accounts audited?

If yes, the applicable due date is generally 31 August 2026.

Step 4: Are you a partner in a firm?

Check whether the firm is subject to audit and whether the partner-specific due-date provisions apply.

Step 5: If none of the above applies

The regular due date may be 31 July 2026.

This is a simplified practical guide. Taxpayers should verify their specific circumstances before relying on a particular deadline.

Income Tax Return Filing Due Dates for AY 2026-27 : What Happens If the ITR Is Filed After the Due Date?

A return filed after the applicable due date is generally treated as a belated return.

For AY 2026-27, taxpayers who miss their applicable original return filing deadline should not simply assume that they have lost the opportunity to file their return.

The Income Tax Department allows a belated return to be filed within the prescribed statutory time limit, subject to the applicable conditions.

However, filing a belated return can have consequences, including:

Late filing fee, where applicable.
Interest on tax payable, where applicable.
Possible loss of the ability to carry forward certain losses.
Other consequences depending on the taxpayer’s circumstances.

The exact consequences depend on the taxpayer’s income, tax liability, and the nature of the return.

Therefore, taxpayers should ideally file their return by the applicable original due date rather than relying on the belated return facility.

What Is the Due Date for a Revised Income Tax Return for AY 2026-27?

A taxpayer who has already filed an Income Tax Return may discover an omission or an incorrect detail in the return.

For example, the taxpayer may have:

Missed reporting a bank interest income.
Entered incorrect income details.
Failed to claim an eligible deduction.
Reported an incorrect amount of tax deducted at source.
Made an error in the computation of total income.

In such cases, the taxpayer may be able to file a revised return, subject to the applicable provisions and statutory deadline.

The revised return is not a separate type of ITR form. It is a return filed to correct or update an earlier return that has already been filed.

Taxpayers should not wait until the end of the revised return window if they discover an error. The correction should be made as soon as the taxpayer identifies the mistake.

The original return should be prepared and filed carefully, with the revised return facility being used to correct genuine errors or omissions.

What Is the Due Date for the Tax Audit Report for AY 2026-27?

The due date for filing the tax audit report is generally earlier than the Income Tax Return filing deadline for taxpayers whose accounts are required to be audited.

For a taxpayer whose ITR filing due date is 31 October 2026, the tax audit report should be furnished within the applicable prescribed timeline.

The tax audit report is a separate compliance requirement from the Income Tax Return.

Therefore, a taxpayer subject to tax audit should track at least two important deadlines:

Tax audit report deadline

The audit report must be furnished within the prescribed time.

Income Tax Return deadline

The ITR must then be filed by the applicable return filing due date.

Taxpayers should coordinate with their tax professionals and auditors well in advance to ensure that both compliances are completed on time.

Waiting until October to begin the audit process can create unnecessary pressure, particularly for businesses with complex books of account or a large volume of transactions.

What Happens If You Miss the Income Tax Return Filing Due Dates for AY 2026-27?

Missing the original Income Tax Return filing due date does not necessarily mean that the taxpayer can no longer file the return.

However, there can be consequences.

Late filing fee

A late filing fee may become payable under the applicable provisions.

Interest on tax payable

If tax remains payable, interest may also be applicable depending on the taxpayer’s circumstances and the period of delay.

Loss of carry-forward of certain losses

Certain losses may not be permitted to be carried forward if the return is not filed within the prescribed original due date.

Delay in receiving a refund

If the taxpayer is entitled to a refund, filing late can also delay the refund process.

Additional compliance complications

A delayed return can sometimes create additional compliance issues, particularly where the taxpayer also has other reporting or audit obligations.

For these reasons, taxpayers should treat the original ITR filing due date as the preferred deadline, even though the law may provide a belated return facility.

Can the Income Tax Return Filing Due Dates for AY 2026-27 Be Extended?

The Government or the Central Board of Direct Taxes may, in appropriate circumstances, extend certain statutory deadlines. Such extensions are generally announced through official notifications or circulars.

Does the New Income-tax Act, 2025 Change the Income Tax Return Filing Due Dates for AY 2026-27?

The introduction of the Income-tax Act, 2025 has created considerable confusion around the filing of returns for AY 2026-27.

However, taxpayers should distinguish between the assessment year and the new tax year system.

The return for AY 2026-27 relates to income earned during FY 2025-26, which ended on 31 March 2026.

The Income Tax Department has clarified that the return for this period continues to be filed under the Income-tax Act, 1961.

The new Income-tax Act, 2025 applies to income earned during tax years beginning on or after 1 April 2026.

Therefore, taxpayers filing their return for AY 2026-27 should not assume that the new Act changes the basic legal framework applicable to that return.

At the same time, taxpayers should be aware that AY 2026-27 is a transition year and should carefully distinguish:

FY 2025-26.
AY 2026-27.
Tax Year 2026-27.

This distinction will become increasingly important as taxpayers begin filing returns under the new tax-year system.
