Understanding the notice

What is a defective return notice?

When the Income Tax Department's Centralised Processing Centre (CPC) processes your return and finds that it is incomplete, inconsistent, or not in conformity with prescribed conditions, it issues an intimation treating the return as defective. The notice clearly states the specific defect(s) and gives you an opportunity to correct them. It is delivered to your registered email and also appears on the e-filing portal under Pending Actions → e-Proceedings.

💬

It is a correction window

A defective notice is not a penalty, audit, or tax demand. If you rectify the defect within the time allowed, your return is accepted as originally filed — with no interest, penalty, or adverse consequence.

The 15-day rule

You generally get 15 days from receipt of the notice to respond. If you need more time, you can apply in writing to the Assessing Officer for an extension before the deadline lapses.

Ignore it, and the return is gone

If the defect is not rectified in time, the original return is treated as invalid (void ab initio) — as if you never filed. That triggers a chain of statutory consequences (detailed below).

Statutory basis — dual citation

The defective return provision has been renumbered under the new Act. We track both for complete legal accuracy and search coverage:

Why you received it

Most common defects that trigger a 139(9) notice

For AY 2026-27 the department's automated filters are stricter than ever. The vast majority of notices arise from technical and procedural mismatches — not deliberate evasion. These are the defects we see most often:

📊

TDS claimed, income not reported

You claimed TDS credit but did not report the corresponding income in the return — the single most common reason for a defect.

💲

Income mismatch with 26AS / AIS / TIS

Income appearing in Form 26AS, AIS or TIS is higher than what you declared in the ITR, creating an inconsistency.

📄

Wrong ITR form used

For example, filing ITR-1 when business or capital-gains income required ITR-2/ITR-3/ITR-4.

📋

Missing Balance Sheet / P&L

You filed ITR-3 but left the Balance Sheet or Profit & Loss schedules blank where they are mandatory.

🧾

Audit report not furnished

Income is shown as audited but the tax audit report (or its figures) does not reconcile with the return.

💳

Tax paid, challan details missing

Self-assessment / advance tax was paid but the challan (BSR code, date, amount) details are not filled in.

The official procedure

How to respond on the e-filing portal

The response is filed online on the income-tax portal. Here is the exact sequence — we handle every step for you, end to end.

Log in to the e-filing portal

Visit incometax.gov.in and log in with your PAN/Aadhaar and password.

Open Pending Actions → e-Proceedings

Locate the notice under e-Proceedings (or For Your Action), select the Section 139(9) notice and click View Notice. Download the PDF using your password (see tool above).

Read the defect description & DIN

Verify the DIN, assessment year and the exact defect(s) raised. Note the response due date stated in the notice.

Choose Agree or Disagree

Click Submit Response. Select Agree to rectify the defect (you'll file a corrected return), or Disagree if you believe the return is correct — with clear reasons.

Prepare & upload the corrected return

Fix the flagged items, regenerate the JSON from the correct ITR utility/form, and upload it against the notice. Pay any balance tax first if applicable.

Submit & e-verify

Submit the response and e-verify the corrected return (Aadhaar OTP / net-banking / EVC). Once accepted, the return is processed as valid. Note: a submitted response cannot be withdrawn.

Your two options

Agree vs. Disagree — which one?

Agree — rectify the defect

Choose this when the defect is genuine. You correct the flagged items (report the missing income, switch to the right form, complete the schedules, add challan details) and file the corrected return against the notice. This is the most common route.

Disagree — with reasons

Choose this only when you are confident the return is already correct and the defect was raised in error. You must record clear, well-supported reasons. This route needs careful judgement — a wrong "Disagree" can lead to your return being invalidated.

💡

Practical relief

Even where a defect is rectified after the 15-day period, in practice the Assessing Officer may — before completing the assessment — exercise discretion to condone the delay and treat the return as valid. This is discretionary, not a right, so always respond within time.

If you ignore the notice

Consequences of non-response

If the defect is not rectified within the prescribed or extended period, the return is treated as invalid — legally equivalent to never having filed. The knock-on effects are real:

ConsequenceWhat it means for you
Return treated as invalidThe original return is void ab initio — treated as if no return was filed at all.
Late-filing fee (Sec 234F)A statutory late-filing fee becomes payable for the belated/non-filing position.
Interest (Sec 234A / 234B)Interest accrues on any tax due for delay in filing and for shortfall in advance tax.
Loss of carry-forwardBusiness and capital losses cannot be carried forward to future years.
Deductions / exemptions deniedCertain deductions and exemptions that require timely filing may be lost.
Refund delay / forfeitureAny refund claimed is held up and may be lost where the return is invalidated.

Questions, answered

Defective notice FAQs

Is a 139(9) defective notice a penalty?
No. It is a correction opportunity, not a penalty or an audit. If you rectify the flagged defect within the time allowed, your return is accepted as originally filed with no interest, penalty or adverse consequence.
How much time do I get to respond?
Generally 15 days from the date of receipt of the notice. You may request an extension by applying in writing to the Assessing Officer before the deadline expires.
What is the password to open the notice PDF?
Your PAN in lower case followed by your date of birth in DDMMYYYY format. For PAN DRQPS1234G and DOB 06/12/1996, the password is drqps1234g06121996. Use the password tool above to generate it.
What happens if I miss the 15-day deadline?
The original return is treated as invalid (void ab initio) — as if no return was filed. This can trigger a late-filing fee under Section 234F, interest under Sections 234A/234B, loss of carry-forward of losses and denial of certain deductions.
Which section applies under the new Income-tax Act, 2025?
Section 139 of the 1961 Act has been renumbered as Section 263 in the 2025 Act. The defective return provision, formerly Section 139(9), now appears as Section 263(7).
Can a Chartered Accountant respond on my behalf?
Yes. You can authorise a representative, such as a Chartered Accountant, to view and respond to the defective notice through the e-filing portal. CA Alok Kumar handles this routinely.
Can I withdraw or edit my response after submitting?
No. Once a response to the defective notice is submitted on the portal, it cannot be updated or withdrawn — which is exactly why the response must be correct the first time.
