The deadline to file Income Tax Returns (ITR) for income earned in FY 2025-26 (AY 2026-27) is 31st July 2026, without late fees. However, if you miss this deadline, you can still file a belated return by 31 December 2026, though a penalty will apply.

Significance of Timely Filing of ITR (Income Tax Return) by 31July 2026
Individuals or entities who file an ITR by or before 31 July 2026, the deadline, will have several advantages as follows:
If 31 July 2026 has passed and the ITR has not been filed, taxpayers can still file a belated ITR and take advantage of these benefits until 31 December 2026. However, there are consequences for doing so:
If the Taxpayer has already filed an original or belated ITR, and have subsequently found an error or omission, they can file a revised ITR (Revised Return) for all types of original ITRs by 31 December 2026.

Failing to file within the due date results in the filing of a belated return, attracting penalties of up to Rs. 5,000. For those with income below Rs. 5 lakh, the fee is reduced to Rs. 1,000.
Businesses with annual turnovers exceeding Rs. 1 crore and professionals with receipts over Rs. 50 lakh need a tax audit.
No penalties or interest are levied for filing income tax returns after the deadline if income falls below the taxable limit.
Revisions to the original return can be made using the revised return u/s 139 if the taxpayer wishes to do so because of some revisions (5). You have until the end of the assessment year, 31 December, to submit a belated return.
A late return, or one that is submitted after the deadline, may be filed in accordance with Section 139(4).
If the taxpayer needs to change the initial return because of some adjustments, they can do so by using a revised return in accordance with Section 139. (5). You may submit a late return on or before 31 December of the assessment year.
In the Union Budget 2026, the Finance Minister Nirmala Sitharaman introduced revised timelines for filing Income Tax Returns. Under the updated provisions, the due date for submitting revised returns has been moved from 31 December to 31 March, subject to a nominal fee. The standard filing deadline for individual taxpayers using ITR-1 and ITR-2 remains 31 July. Additionally, the last date for revised returns for non-audit individuals has been extended to 31 August. These changes are intended to provide taxpayers with additional time to amend or update their submissions.
