Can I File Income Tax Return (ITR) After the Due Date? Explained

Yes, if you miss the original Income Tax Return (ITR) filing deadline, you can still file your return as a belated return up to 31st December of the relevant assessment year. Even after this deadline, taxpayers have another option to file an updated return within 48 months (4 years) from the end of the relevant assessment year.

The key differences between a belated return and an updated return are explained below:

Basis of Differentiation	Belated Return	Updated Return
Who can file	Taxpayers who miss the original ITR filing deadline	Taxpayers who miss both original and belated return deadlines
Due date	31st December of the assessment year	31st March after completion of 4 years from the end of the assessment year
Due date for FY 2025-26 (AY 2026-27)	31st December 2026	31st March 2031

What to Do If Your Income Tax Return (ITR) Has Errors? Explained

Revised Return

A revised return allows taxpayers to correct mistakes made in the original ITR filing, such as missing deductions, incorrect income details, or wrong reporting of tax information.

The due date for filing a revised return is 31st March of the assessment year.

Example:
Mr. X filed his ITR for FY 2025-26 on 30th June 2026. Later, on 1st August, he realized that he missed claiming certain deductions. In this case, he can file a revised return anytime before 31st March 2027 to correct the error.

Updated Return

If you miss the deadline for filing a revised return, you can still file an updated return within 48 months (4 years) from the end of the relevant assessment year.

An updated return can be filed even if no original return was filed earlier. However, it does not allow taxpayers to claim additional benefits that were not included in the original or revised return. Also, once filed, an updated return cannot be revised again.

Understanding these options helps taxpayers stay compliant and correct errors in their income tax filings within the permitted timelines.

Consequences of Missing the Income Tax Return (ITR) Filing Deadline Explained

1. Interest on Late Payment

If you file your return after the due date, you will be liable to pay interest under Section 234A at 1% per month (or part of a month) on the outstanding tax amount until the return is filed.

2. Late Filing Fee

Under Section 234F, a late filing fee is applicable in case of delayed ITR filing:

₹5,000 if total income exceeds ₹5 lakh
₹1,000 if total income is up to ₹5 lakh

3. Loss of Carry Forward Benefits

Taxpayers are allowed to carry forward certain losses such as capital losses from shares, mutual funds, or property, as well as business losses, to offset future income and reduce tax liability.

However, if the ITR is not filed within the due date, these losses cannot be carried forward to future years, resulting in a higher tax burden.

4. Impact on Financial Reputation

Late filing of ITR may also negatively affect your financial credibility. It can lead to delays or rejection in loan approvals, as it reflects poor financial discipline. It may also create challenges during visa processing and other financial verifications.

5. Reference to Income Tax Law Changes

Although the Income Tax Act, 2025 is set to be effective from 1st April 2026, the provisions of the Income Tax Act, 1961 continue to apply for AY 2026-27, as they relate to income earned up to 31st March 2026.

Topic	Income Tax Act 1961	Income Tax Act 2025
Interest for late/non-filing of return	Section 234A	Section 423
Late filing fee	Section 234F	Section 428
