What is an Income Tax Notice?
An income tax notice is an official letter sent by the Income Tax Department to a taxpayer. It informs the taxpayer about an issue or query related to their tax return or tax payments. The notice could be about missing information, discrepancies in the filed return, tax assessments, or a request for additional documents. When a taxpayer receives such a notice, they are required to respond within the given time to resolve the matter with the tax authorities.

The Income Tax Department issues various types of notices depending on the reason for communication. Some common types include:
- Notice under Section 142(1): Requests additional information or documents related to your filed return, or asks you to file a return if not filed.
- Notice under Section 139(9): Issued when a return filed is found to be defective or incomplete.

Intimation Under Section 143(1)
Once you file your Income Tax Return (ITR), it is electronically processed by the Central Processing Centre (CPC). During processing, the income is recalculated after making certain automatic adjustments, such as:
- Correction of any arithmetical errors
- Disallowance of incorrect claims is clearly evident from the return
- Rejection of losses or expenses wrongly claimed
- Addition of income not reported in the return
After processing, the CPC issues an Intimation under Section 143(1) in any of the following three cases:
- Tax is payable by the taxpayer
- Refund is due to the taxpayer
- No tax or refund, but there is a change in the amount of loss carried forward
The intimation must be sent within 9 months from the end of the financial year in which the return was filed.
Example: If your return for AY 2024–25 was filed on 27 July 2024, the intimation can be issued up to 31 December 2025.
Note: Processing under Section 143(1) has been mandatory since Assessment Year 2017–18.
How to Analyse an Intimation u/s 143(1)?
Review the comparison between the figures filed in your ITR and the ones recalculated by the CPC.
Identify any mismatches in:
- Income
- Deductions
- TDS or prepaid taxes
If the mismatch or demand is due to an error, you can file a rectification request under Section 154 within 4 years from the end of the relevant assessment year.
If the tax demand is correct, pay the amount using the payment link provided in the intimation.
Notice Under Section 143(2)
A notice under Section 143(2) is issued when your income tax return is selected for scrutiny. This means the Assessing Officer (AO) wants to examine your return in detail to ensure that:
- You have not understated your income
- You have not claimed excessive losses
- You have not paid less tax than required
This notice is usually followed by a questionnaire and a request for supporting documents. The AO must issue this notice within 3 months after the end of the relevant assessment year.
Example: If Mohan filed his return on 19 June 2024 for AY 2024–25, then the last date for issuing notice under Section 143(2) would be 31 August 2025.
