Defective Return Notice: Evidence Pack and Response Workflow

Finin2min Tax Desk·June 2026·9 min readDEFECTIVE RETURNValidated: 17 June 2026

A defective return notice should be handled by mapping the exact defect, correcting the underlying schedule/data issue, and responding within the portal workflow with supporting computation.

Detailed analysis

How to read the notice
Do not start editing the return immediately. First authenticate the notice, identify assessment year, return form, defect code/reason, response deadline and whether the issue is data mismatch, missing schedule, audit information, tax payment or computation inconsistency.

Practical example

Example
A taxpayer reports business income but misses balance sheet/profit and loss details in the selected ITR utility. The response should include corrected return data, business schedules and computation — not a generic letter saying income is correct.
