How to respond to a notice under Section 143(1)

If there are no adjustments, there is no need to respond to an intimation under Section 143(1). However, if a taxpayer disagrees with the adjustments made or needs to provide additional information, they should respond within the specified time frame.



The following steps are required to respond to a notice under Section 143(1):

  • Firstly, verify personal details, review all eligible deductions and exemptions claimed in your return and income details whether it have been accurately considered.
  • Provide appropriate explanations, supporting documents, or corrections.
  • Send your response within the specified time, either online through the income tax e-filing portal or by visiting a designated office.

Time Limit to respond

The time limit is within nine months from the end of the financial year in which the return is filed.

For example, if a taxpayer files a return for the financial year 2022-23 in July 2023, the intimation can be sent within 31 December 2024.

If no intimation is received within this period, it means there are no adjustments to the filed return, and the acknowledgement filed is deemed to be the Section 143(1) intimation.
