Defective return notice under section 139(9)

A defective return notice means the Income Tax Department has found incomplete, inconsistent or incorrect information in your ITR. You need to read the notice, identify the defect, correct the return response and submit it within the allowed time.

Do not ignore it: A defective return can become invalid if the defect is not corrected within the timeline mentioned in the notice.

Common reasons for 139(9) notice

TDS credit claimed but matching income not reported.
Receipts in Form 26AS or AIS are higher than income shown in the return.
Business or professional income reported without required balance sheet, profit and loss or schedule details.
Name or PAN mismatch.
Return form selected incorrectly for the income profile.
Tax paid but gross total income or relevant schedules shown incorrectly.

Examples

TDS without income

You claimed TDS from Form 26AS but forgot to report the related professional receipt. The response must correct the income and tax computation.

Wrong ITR form

You used ITR-1 but had capital gains or business income. The correct response may require filing details in the applicable form or schedule.

Missing business schedules

You reported freelance income but left business schedules blank. The defect response should complete the required financial details.

How to respond

Download the notice and note the assessment year, DIN, section and response due date.

Identify whether the defect is factual, computation-related or form-selection related.
Prepare corrected return data or response details.
Submit the response on the e-filing portal and keep the acknowledgement.
