A defective-return notice does not automatically mean tax evasion. It means the return has incomplete, inconsistent or insufficient information that the portal/department wants corrected or explained. The danger is missing the response window or submitting a casual response without fixing the actual defect.
Official Section 139(9) text says that where the Assessing Officer considers a return defective, the taxpayer may be intimated and given an opportunity to rectify the defect within 15 days or such further period as may be allowed. If not rectified, the return can be treated as invalid.
| Defect pattern | What it usually means | Fix control |
|---|---|---|
| TDS credit claimed but corresponding income omitted | Tax credit is claimed but income schedule does not support it. | Add/align income or correct credit claim. |
| 26AS receipts higher than income shown | Reported receipts exceed return disclosure. | Reconcile gross receipts and schedules. |
| Income heads entered nil but tax liability computed | Return schedules inconsistent. | Correct income/tax computation fields. |
| Name mismatch with PAN database | Identity mismatch. | Correct profile/PAN data issue as applicable. |
| Business income but balance sheet/P&L not filled | Business schedule incomplete. | Fill required financial particulars or use correct ITR form. |
The e-Proceedings user manual says taxpayers can view the notice, download it, submit response, choose Agree or Disagree, upload the corrected JSON where applicable, and keep the transaction ID after submission. The portal FAQ also says a submitted response cannot be updated or withdrawn.
