Comprehensive response guide for Income Tax notices under Section 143(1), defective return 139(9), scrutiny 143(2), and reassessment under 148. Learn how to respond on the e-filing portal.
In This Article
5 SectionsReceiving an Income Tax notice on the e-filing portal or by email can cause anxiety. However, a significant percentage of notices issued today are automated communications generated by the Centralized Processing Centre (CPC) to seek routine clarification or rectify data mismatches.
Understanding the specific section under which the notice is issued is the first step toward resolving the issue without incurring penalties or interest.
Key Rule of Action: Never ignore an Income Tax notice. Under the Income Tax e-Proceeding system, failing to respond within the stipulated time limit (usually 15 to 30 days) allows the department to pass an ex-parte assessment order under Section 144 (Best Judgment Assessment).

2. Detailed Breakdown of Key Notice Types
A. Section 143(1) Intimation (Tax Demand or Adjustment)
When you file your Income Tax Return (ITR), the CPC processes it electronically and issues an Intimation under Section 143(1). This document displays two parallel columns:
- As Provided by Taxpayer in Return
- As Computed under Section 143(1)
Common Mismatches Triggering Demand:
- Disallowance of deductions under Chapter VI-A (80C, 80D) if details were not pre-filled or supported by Form 16/16A.
- Mismatch in TDS claimed vs TDS reflected on TRACES Form 26AS.
- Omission of savings bank interest, FD interest, or dividend income captured in AIS.
B. Section 143(2) Scrutiny Notice (Faceless Assessment)
A notice under 143(2) indicates that your return has been selected for detailed examination by the National Faceless Assessment Centre (NFAC). Selection can be:
- Limited Scrutiny: Focused strictly on specified parameters (e.g., cash deposits during demonetization, high-value real estate purchase, large foreign remittance).
- Complete Scrutiny: Comprehensive audit of entire books of account, bank statements, and business operations.
C. Section 148 Reassessment Notice (Reopening Past Years)
Under Section 148, the Assessing Officer reopens an assessment if they possess "information suggesting that income chargeable to tax has escaped assessment."
- Reopening is generally permitted up to 3 years from the end of the relevant assessment year.
- In cases involving serious tax evasion where evidence shows escaped income exceeds Rs. 50 Lakhs (e.g., undisclosed land transactions or offshore accounts), the limit extends to 10 years.
3. Step-by-Step Action Plan to Respond
[Receive Notice] ➔ [Verify DIN on Portal] ➔ [Download AIS & Form 26AS] ➔ [Draft Written Response] ➔ [Submit via e-Proceedings]
Step 1: Verify the Document Identification Number (DIN)
Every genuine communication from the Income Tax Department must carry a unique, system-generated DIN.
- Go to the e-filing portal (
incometax.gov.in). - Click "Authenticate Notice/Order Issued by ITD".
- Enter the DIN. If the portal shows "No record found", the notice is invalid.
Step 2: Download AIS, TIS, and Form 26AS
Log into your e-filing dashboard and download your Annual Information Statement (AIS) and Taxpayer Information Summary (TIS). Compare every line item (bank interest, mutual fund redemptions, share trading, property sales) against your filed return.
Step 3: Draft a Structured Written Response
Prepare a written reply addressing each query point-by-point. Attach supporting documents in PDF format:
- Bank account statements highlighting relevant transactions.
- Purchase invoices, sale deeds, or agreement copies.
- Reconciliations of TDS certificates (Form 16A) vs books of account.
Step 4: Submit Online Response under "Pending Actions"
Navigate to Pending Actions ➔ e-Proceedings on the e-filing portal. Upload your response and attachments under the specific notice tab. Ensure you request an acknowledgment receipt.
4. Real-World Case Example: Property Sale Mismatch in Raipur
A resident in Civil Lines, Raipur sold a commercial plot for Rs. 75 Lakhs. The stamp duty valuation (guideline value) was Rs. 88 Lakhs. In the ITR, capital gains were computed using Rs. 75 Lakhs as full value of consideration.
Result: CPC issued a 143(1) intimation invoking Section 50C, substituting the stamp duty value (Rs. 88 Lakhs) and raising a tax demand of Rs. 3.90 Lakhs plus interest.
Resolution: Our team filed a rectification application under Section 154 and submitted evidence that the difference was within the 10% tolerance band permitted under Section 50C(1) proviso, successfully extinguishing the tax demand.
5. Consequences of Default & Appeal Options
If an adverse assessment order is passed despite your response:
- Section 154 Rectification: For clear mistakes apparent from the record (e.g., credit of prepaid tax ignored).
- Section 246A Appeal to CIT(Appeals): Must be filed within 30 days of service of the assessment order, accompanied by Form 35 and payment of 20% of the disputed tax demand.
