Introduction
Income tax terminology can confuse taxpayers, especially when they miss the ITR deadline or discover a mistake after filing their return.
However, deciding between a belated return and a revised return is easier than it appears. You only need to answer one basic question: Have you already filed an income tax return for the relevant assessment year?
If you have not filed any return and the original due date has passed, you generally need to file a belated return. On the other hand, if you have already filed an original or belated return and later discover a mistake, you need to file a revised return.
For Assessment Year 2026–27, which relates to income earned during Financial Year 2025–26, different deadlines apply to belated and revised returns. Therefore, taxpayers in Greater Noida and other parts of India should understand these deadlines before taking further action.
What Is a Belated Return?
A belated return is an income tax return filed after the applicable original due date.
For example, suppose a salaried taxpayer had to file their return by 31 July 2026 but missed the deadline. Since the taxpayer did not file any return by the due date, they can file a belated return under Section 139(4).
Similarly, a taxpayer with non-audit business or professional income may have an original due date of 31 August 2026 for AY 2026–27. If that taxpayer misses the deadline, they may file a belated return, subject to the prescribed time limit.
In simple words, a belated return gives you another opportunity to file your ITR after missing the normal deadline.
What Is a Revised Return?
A revised return allows you to correct a return that you have already filed.
You may file a revised return when you discover an omission, incorrect entry, calculation error or wrong disclosure in your original or belated return.
For example, you may need to revise your return when you:
- forgot to report bank interest;
- missed income appearing in AIS, TIS or Form 26AS;
- entered an incorrect bank account;
- claimed the wrong deduction;
- reported income under the wrong head;
- entered an incorrect TDS amount;
- selected the wrong ITR form; or
- made an error while calculating income or tax.
A revised return does not represent a separate additional return for the same income. Instead, it corrects and replaces the details reported in the earlier return for processing purposes.
The Main Difference Between Belated and Revised Returns
The main difference depends on whether you have already filed a return.
If you have not filed any return and the original deadline has passed, file a belated return.
If you have already filed an original or belated return and need to correct it, file a revised return.
Therefore, you should not file a revised return when you never filed an earlier return. Similarly, you do not need a belated return merely because you found a mistake in an ITR that you already submitted.
Key Differences at a Glance for AY 2026–27
| Feature | Belated Return | Revised Return |
|---|---|---|
| Relevant section | Section 139(4) | Section 139(5) |
| Basic condition | You did not file the original return by the applicable due date | You already filed an original or belated return |
| Main purpose | To file a missed ITR after the deadline | To correct an error or omission in an already-filed ITR |
| Deadline for AY 2026–27 | 31 December 2026 | 31 March 2027 |
| Earlier completion of assessment | Return must be filed before completion of assessment if it occurs earlier | Return must be revised before completion of assessment if it occurs earlier |
| Late-filing fee | ₹1,000 or ₹5,000 under Section 234F, depending on total income | No Section 234I fee up to 31 December 2026; ₹1,000 or ₹5,000 if revised from 1 January to 31 March 2027 |
| Interest | Section 234A interest may apply when tax remains unpaid | Further interest may apply if the revision increases tax payable |
| Carry-forward of certain losses | Generally not available for business, speculative, F&O or capital losses | Available if the original loss return was filed within the applicable original due date |
| Can it be revised? | Yes | A revised return may generally be revised again within the permitted time |
| Tax-regime choice | A late return generally cannot create a tax-regime option that had to be exercised by the original due date | Revision cannot restore an option that was not validly exercised by the original due date |
The Income Tax Department confirms that taxpayers can file a belated return for AY 2026–27 up to 31 December 2026. It also confirms that taxpayers can file a revised return up to 31 March 2027, subject to the completion of assessment occurring earlier.
Due Date for Filing a Belated Return
For AY 2026–27, you can file a belated return up to:
31 December 2026
However, if the Income Tax Department completes the assessment before this date, you must file the return before the completion of that assessment.
Therefore, you should not wait until the last day. Filing early gives you time to identify errors, pay any outstanding tax and complete e-verification.
Due Date for Filing a Revised Return
For AY 2026–27, you can file a revised return up to:
31 March 2027
However, you must file it before the completion of assessment if the assessment gets completed earlier.
The government extended the revised-return time limit for AY 2026–27 up to the end of the assessment year. Previously, taxpayers generally had to revise their return by 31 December.
Nevertheless, a fee may apply if you file the revised return after 31 December 2026.
Fees for Filing a Belated Return
Section 234F imposes a late-filing fee when you file your return after the original due date.
For AY 2026–27, the fee generally applies as follows:
| Total income | Late-filing fee |
|---|---|
| Total income up to ₹5 lakh | ₹1,000 |
| Total income above ₹5 lakh | ₹5,000 |
The portal may calculate the fee automatically based on your income and filing status.
In addition, interest under Section 234A may apply when you have unpaid tax liability. The law generally calculates this interest at 1% per month or part of a month for the relevant period.
However, a taxpayer who has already paid the full tax through TDS, advance tax or other credits may not have interest under Section 234A, depending on the final tax computation.
Is There a Fee for Filing a Revised Return?
A revised return does not automatically attract a late-filing fee merely because you revised an earlier return.
For AY 2026–27, you can revise the return up to 31 December 2026 without paying the new fee under Section 234I.
However, if you file the revised return between 1 January 2027 and 31 March 2027, Section 234I may impose the following fee:
| Total income | Fee under Section 234I |
|---|---|
| Total income up to ₹5 lakh | ₹1,000 |
| Total income above ₹5 lakh | ₹5,000 |
Therefore, the statement that a revised return never attracts any fee is not fully correct for AY 2026–27. The fee depends on when you file the revised return.
Moreover, if you revise a belated return, the late fee already applicable to the belated return does not disappear.
When Should You File a Belated Return?
You should file a belated return when you completely missed the applicable original ITR deadline.
For example, file a belated return when:
- you forgot to file your income tax return;
- you did not receive all documents before the deadline;
- you were unaware that you had to file an ITR;
- you had taxable income but missed the filing date;
- you had TDS deducted and now want to claim the eligible refund; or
- you discovered an income-tax filing requirement after the due date.
Suppose a salaried taxpayer in Greater Noida had taxable salary and fixed-deposit interest during FY 2025–26. The taxpayer did not file the ITR by 31 July 2026.
Since no return was filed by the original due date, the taxpayer should file a belated return. The taxpayer should not select the revised-return option because there is no earlier return to revise.
Consequences of Filing a Belated Return
Although a belated return helps you complete your tax compliance, late filing may lead to several consequences.
Late-filing fee
You may have to pay a fee under Section 234F.
Interest on unpaid tax
You may have to pay interest under Section 234A if tax remains payable after adjusting TDS, TCS, advance tax and other eligible credits.
Loss of carry-forward benefits
You generally cannot carry forward certain losses when you file the return after the original due date.
These losses include:
- normal business loss;
- speculative business loss;
- F&O trading loss;
- short-term capital loss;
- long-term capital loss; and
- loss from owning and maintaining racehorses.
However, a taxpayer may carry forward house-property loss even when the return was filed late. The rules relating to unabsorbed depreciation also differ from the rules for normal business losses.
Restrictions on certain deductions and exemptions
Some deductions, exemptions and other benefits require the taxpayer to file the return within the original due date.
Therefore, filing a belated return may prevent you from claiming benefits that specifically depend on timely filing.
Delay in receiving a refund
You may still claim an eligible refund through a belated return. However, late filing can delay processing, and the rules may restrict interest on the refund for the period attributable to the taxpayer’s delay.
When Should You File a Revised Return?
You should file a revised return when you have already filed an ITR but later discover a mistake or missing detail.
For example, you may file a revised return when:
- AIS shows interest that you did not report;
- you forgot to disclose a mutual fund or share transaction;
- you entered the wrong salary amount;
- you claimed an incorrect deduction;
- you entered an incorrect bank account number;
- you selected an incorrect ITR form;
- you reported capital gains incorrectly;
- you forgot to claim eligible TDS credit; or
- you calculated your tax incorrectly.
Before filing the revised return, compare your original return with AIS, TIS, Form 26AS, bank statements, Form 16, Form 16A and investment records.
This review will help you correct all errors together instead of filing several revisions.
Can You Revise a Belated Return?
Yes. You can revise a belated return if you later discover an omission or incorrect statement.
For example, suppose a taxpayer files a belated return on 15 November 2026. Later, the taxpayer discovers that they forgot to report savings account interest.
The taxpayer can file a revised return and add the omitted interest. For AY 2026–27, the taxpayer may revise the return up to 31 March 2027 or before completion of assessment, whichever occurs earlier.
However, filing a revised return does not remove the consequences of the original late filing. For instance, it does not restore the right to carry forward a capital or business loss when the taxpayer failed to file the original loss return within the due date.
Can You Revise a Revised Return?
Yes. If you discover another mistake after filing a revised return, you may generally revise it again within the permitted time.
However, you must enter the details of the latest valid return while filing the next revision.
Since repeated revisions may increase the possibility of mismatch or scrutiny, review all supporting records carefully before submitting the return.
Can You Change the Tax Regime in a Belated or Revised Return?
The new tax regime operates as the default regime for eligible taxpayers. A taxpayer who wants to choose the old tax regime must exercise the option within the prescribed time.
For taxpayers without business or professional income, the taxpayer generally needs to choose the old regime through an ITR filed on or before the original due date under Section 139(1).
For taxpayers with business or professional income, the taxpayer generally needs to file Form 10-IEA on or before the applicable original due date.
Therefore, a belated return cannot normally create a fresh right to choose the old tax regime after the deadline has passed.
Similarly, a revised return cannot restore a regime option that the taxpayer failed to exercise within the prescribed original time. Taxpayers should review business and non-business cases separately because different procedural requirements apply.
Does a Revised Return Replace the Earlier Return?
Yes. The Income Tax Department processes the revised return in place of the earlier return.
Therefore, you must include all income, deductions, tax payments and other relevant details in the revised return. You should not report only the corrected amount.
For example, if you forgot to disclose bank interest of ₹20,000, you should not prepare a return containing only ₹20,000. Instead, you should prepare the complete return again and add the omitted interest to the correct income details.
Practical Examples
Example 1: No return filed by the due date
Rohit, a salaried employee in Greater Noida, had to file his ITR by 31 July 2026. However, he did not file it.
Rohit should file a belated return because he has not submitted any earlier return.
Example 2: Return filed, but bank interest omitted
Meena filed her original return on 20 July 2026. Later, she noticed that she had not reported fixed-deposit interest shown in AIS.
Meena should file a revised return because she has already filed an original return and now needs to correct it.
Example 3: Error found in a belated return
Amit filed a belated return on 10 December 2026. Later, he discovered that he entered the wrong TDS amount.
Amit can file a revised return to correct the mistake. However, the original consequences of filing late will continue to apply.
Example 4: Capital loss reported in a belated return
Neha incurred a capital loss during FY 2025–26 but filed her return after the original due date.
She can report the transaction in the belated return. However, she generally cannot carry forward that capital loss because she did not file the loss return within the original due date.
Simple Decision Rule
Use the following rule to choose the correct return:
No return filed and the original deadline has passed → File a belated return.
Return already filed and you need to correct a mistake → File a revised return.
If the normal belated and revised return deadlines have also expired, you may need to examine whether you can file an updated return or ITR-U. However, ITR-U follows separate eligibility conditions and generally cannot reduce tax liability or increase a refund.
How to File a Belated or Revised Return
You can file both returns through the official Income Tax e-Filing Portal.
First, log in to your account and select the relevant assessment year. Next, choose the applicable ITR form and select the correct filing section.
For a belated return, select Section 139(4).
For a revised return, select Section 139(5) and enter the acknowledgement number and date of the earlier return.
After that, complete the full return, calculate the tax, pay any outstanding amount and submit the ITR. Finally, e-verify the return through Aadhaar OTP, net banking, EVC, DSC or another permitted method.
Conclusion
A belated return and a revised return serve two different purposes.
You should file a belated return when you missed the original ITR deadline and did not file any return. In contrast, you should file a revised return when you have already filed an original or belated return but need to correct an error or omission.
For AY 2026–27, you can generally file a belated return up to 31 December 2026. Meanwhile, you can file a revised return up to 31 March 2027. However, a fee under Section 234I may apply when you revise the return after 31 December 2026.
Therefore, taxpayers should not delay their filing. They should review AIS, TIS, Form 26AS, bank statements and other financial records before submitting the return.
Taxpayers and businesses in Greater Noida may seek professional assistance when the return involves business income, capital gains, F&O transactions, foreign assets, carried-forward losses or an incorrect tax-regime selection.
