Defective ITR notices: 15-day deadline to respond, revised return options
Every year, people in India who earn money must tell the government about it by filling a form called an ITR.
There are different ITR forms for different kinds of people, such as salaried workers and business owners.
Sometimes a person fills the wrong form or makes a small mistake, and the government sends a notice saying the form is 'defective,' which means it has a problem.
When this happens, the person has 15 days to fix the mistake.
If they do not fix it in time, the form may be treated as invalid, as if they never filed it.
That can mean extra charges called penalties and interest.
It can also mean losing benefits, like the ability to carry forward losses to future years.
People can fix their form by filing a revised return online through the income tax portal.
They have until 31 March 2027 to do that for this year's taxes.
If the mistake was genuine and fixed in time, there is usually no direct penalty for picking the wrong form.
The Income Tax Department can flag an ITR as defective under Section 139(9) of the Income-tax Act, 1961 for incomplete, inconsistent, or incorrect information.
Taxpayers get 15 days from the date of receiving the notice to rectify the defect, or the time specified in the notice.
Common reasons include claiming TDS without reporting related income, mismatched gross receipts in Form 26AS, tax liability despite zero income, PAN name mismatch, and incomplete business details.
Ignoring the notice may cause the return to be treated as invalid, leading to penalties, additional interest, and loss of carry-forward losses and exemptions.
For AY 2026–27, taxpayers can file a revised return by 31 March 2027 or before assessment completion, or an updated return (ITR-U) within 48 months of the assessment year.
