Revised Income Tax Return: Deadline and Reasons Explained
Imagine you filed your homework, but then realized you forgot to add a math problem or wrote down the wrong date.
A revised tax return is like going back to your teacher to fix those mistakes in your homework.
You can do this for your taxes if you find an error or forget to include something.
You have to do this before the end of the school year (assessment year) and it's a way to make sure your tax return is correct.
This is different from an updated return, which is like submitting a whole new homework assignment much later, and you might have to pay extra for being late.
Reasons to fix your tax return include forgetting to mention money you earned, or making a mistake with your personal details.
It's important to correct these issues so your tax information is accurate.
Taxpayers can file a revised Income Tax Return (ITR) to correct mistakes made in the original filing.
A revised return must be filed under Section 139(5) of the Income Tax Act within the same assessment year.
The deadline to file a revised return for AY 2025-26 is December 31.
Reasons for filing a revised return include missing income sources, or errors in personal information and dependents.
Revising a return is distinct from filing an updated return, which can be done later with additional penalties.
