Revised ITR AY 2026-27: Deadline, Process & Mistakes

Filed your Income Tax Return for AY 2026-27 and later noticed a mistake? You may be able to correct it by filing a Revised ITR. This can be useful when some income was left out, incorrect information was entered, or a claim or tax detail needs to be corrected.

A revised return is filed under Section 139(5) of the Income Tax Act, 1961. Before submitting it, you should check the original return along with your income and tax records so that the revised return contains complete and accurate information.

What Is a Revised ITR?

A Revised ITR is a return filed after the original ITR has already been submitted. It is used when a taxpayer finds an omission or an incorrect statement in the original return.

Some common reasons for filing a revised return include:

  • Income was entered incorrectly

  • A source of income was missed

  • Incorrect personal or bank details were provided

  • An eligible deduction was not reported correctly

  • TDS or tax details need correction

  • Information in an ITR schedule was entered incorrectly

When preparing the revised return, it is better to check the complete ITR rather than changing only the figure where the mistake was noticed.

Who Can File a Revised ITR for AY 2026-27?

If you have already filed your Income Tax Return for AY 2026-27 and later find an omission or incorrect statement, you can generally file a revised return under Section 139(5), provided the applicable conditions and time limit are met.

This can apply to different types of taxpayers, including salaried individuals, freelancers, professionals and business owners.

For people filing ITR-3 or ITR-4, the income details, deductions, tax information and applicable schedules should be checked carefully before filing the revised return.

What Is the Deadline for Revised ITR AY 2026-27?

For AY 2026-27, the general time limit for filing a revised return is 31 March 2027, or before completion of the assessment, whichever is earlier, subject to the applicable rules.

If you have already found a mistake in your return, there is generally no benefit in waiting until the last day. Reviewing the return early gives you time to check the supporting documents and make the required corrections.

Taxpayers should also check whether any additional fee or other requirement applies based on when the revised return is filed.

How to File a Revised ITR for AY 2026-27

Filing a revised return starts with checking the return that was originally submitted.

1. Check Your Original ITR

Open your previously filed return and identify the information that needs to be changed or added. Note the acknowledgement details of the original return as these may be required while filing the revised return.

2. Match Your Income and Tax Details

Check your Form 16, Form 16A, AIS, Form 26AS, bank statements and other relevant records. This can help you identify missing income or differences in TDS and tax information.

3. Select AY 2026-27

For income earned during FY 2025-26, the relevant assessment year is AY 2026-27.

4. Choose the Revised Return Option

On the Income Tax e-Filing portal, select the option for filing a revised return under Section 139(5) and enter the required details of the original return.

5. Make the Corrections

Update the information that was incorrect or missing. Also check the other schedules and calculations because one change can affect the total income or tax payable.

6. Submit and Verify

After submitting the revised ITR, complete the applicable verification process. Keep the acknowledgement and records related to the revised filing for future reference.

Common Mistakes While Filing a Revised ITR

A revised return should not be treated as simply replacing one incorrect number. The entire return deserves a quick review.

Selecting the wrong ITR form:
The appropriate ITR form depends on your income and other circumstances. Business and professional taxpayers should particularly check whether ITR-3 or ITR-4 applies to them.

Not checking AIS and Form 26AS:
Differences between the return and available tax information can lead to problems later. Check these records before submitting the revised return.

Leaving out other income:
If another source of income was missed in the original return, make sure the revised return includes the applicable details.

Repeating the original mistake:
While preparing the revised ITR, compare the corrected information with your supporting documents instead of copying the original return without checking it.

Not verifying the return:
After filing, make sure the revised return is properly verified.

Revised ITR vs Belated ITR

A Belated ITR is filed when the original return was not filed within the applicable due date.

A Revised ITR is filed when the original return has already been filed and an eligible mistake or omission needs to be corrected.

So, the two are used for different situations. If you have already filed your return and later find an error, you should check whether the revised return facility is applicable to your case.

Revised ITR vs ITR-U

A Revised ITR and ITR-U (Updated Return) are also different.

A revised return is generally used for correcting an eligible omission or incorrect statement in an already filed return within the permitted period. ITR-U is a separate return mechanism with its own eligibility conditions, time limits and tax implications.

Before choosing between the two, taxpayers should check the rules that apply to their particular situation.
