ITR Filing: Missed the Deadline? You Can Still Fix Errors Until Dec 2025
Revised ITR Filing Deadline: Fix Errors Until Dec 31, 2025

The deadline for filing income tax returns for the financial year 2023-24 concluded on September 16 after receiving two extensions. However, taxpayers who have identified errors or omissions in their originally filed returns still have an opportunity to correct them through the revised return mechanism.

What is a Revised Income Tax Return?

The provision for revising income tax returns is established under Section 139(5) of the Income Tax Act. This facility allows taxpayers who have already submitted their returns under sub-section (1) or (4) to file a revised return if they subsequently discover any omissions or incorrect statements in their original filing.

The revised return essentially replaces the original submission, providing taxpayers with a legal means to correct genuine mistakes without facing penalties for unintentional errors.

Revised Return Deadline for Assessment Year 2025-26

According to income tax regulations, a revised return can be filed until three months before the conclusion of the assessment year or before the assessment process begins, whichever occurs earlier. For the assessment year 2025-26, this translates to a final deadline of December 31, 2025.

This extended window gives taxpayers ample time to review their filings, gather missing documents, and ensure complete accuracy in their tax declarations.

Key Differences Between Revised and Updated Returns

Many taxpayers confuse revised returns with updated returns, but these are distinctly different concepts under Indian tax law.

Revised returns are specifically for correcting mistakes discovered within the same assessment year. In contrast, updated returns can be filed within 48 months following the end of the assessment year, but require payment of additional tax along with penalties.

The updated return facility is designed for situations where taxpayers completely missed filing or need to declare additional income after the revision period has expired.

Common Reasons for Filing Revised Returns

Taxpayers typically file revised returns for several specific reasons:

One of the most frequent scenarios involves unreported income sources. After submitting their original return, taxpayers might realize they omitted certain earnings such as capital gains from investments, interest income from savings accounts or fixed deposits, or income from freelance work.

Another common situation relates to changes in dependents. Life events may necessitate adding or removing dependents from tax calculations, which directly impacts deductions and exemptions claimed.

Simple errors in personal information also prompt revisions. These might include incorrect bank account numbers for refund processing, errors in address details, mistakes in PAN or Aadhaar linking, or inaccuracies in other identification particulars.

Additionally, taxpayers often revise returns to claim missed deductions under various sections like 80C, 80D, or 24(b), or to correct calculations regarding house property income, business profits, or other income heads.

The income tax department's revised return facility demonstrates understanding that tax filing can be complex, and provides a structured method for citizens to maintain accurate financial records with the government.
