Section 143 (1) - Income Tax Act

Section 143 (1) - Income Tax Act

The Centralized Processing Center processes all of the taxpayers' income tax returns (CPC). Once the processing of the income tax return is completed, the income tax department notifies the taxpayers of the outcomes pursuant to section 143(1) - Income Tax Act. 

The CPC system generates the notification of Section 143(1) intimation which typically shows evident problems found by the mainframe system in the filed tax return.

What is Section 143(1) intimation?

In every financial year, everyone who has taxable income is required to submit an income tax return. The Income Tax Department will process the return and check for problems when the taxpayer files his or her taxes. In the event that there are small mistakes on the income tax returns, a summary assessment may be made in accordance with Section 143(1) of Income Tax Act without contacting the assessee. In addition, the assessee receives a Letter of Intimation or Income Tax Notice from the IT Department in accordance with Section 143 of the Income Tax Act. If a taxpayer receives this notification, he or she should make an effort to comprehend it and abide by the Tax Officer's requirements.

Let’s dive deeper into the details of Section 143 (1) of income tax in this article.

Why is the Intimation u/s 143(1) Issued?

The intimation of Section 143(1) is issued to a taxpayer for the reasons mentioned below:

  • If the taxpayer overpays his/her taxes, a tax return amount will be mentioned in the message. The taxpayer will receive a refund if the amount is greater than Rs. 100. Refunds with amounts less than Rs. 100 won't be given out.
  • The notification will state the amount of tax payable by the concerned taxpayer and include a challan for the same payment if the taxpayer has paid taxes that, after computation, are discovered to be short. 
  • A straightforward statement that the assessing officer's calculations and the taxpayer's tax filings are consistent. In certain situations, the assessee does not get a formal notification and should instead consider the ITR V acknowledgment of submitting an income tax return to be the notification.

How Much Time Does One Have to Assess a Section 143 (1) Intimation?

Within a year of the conclusion of the financial year in which the income tax return is filed, a taxpayer may assess a Section 143(1) of income tax notice. The deadline for receiving a letter of notification is March 31, 2022. 

For instance, if a taxpayer has filed returns for the years 2020–21. If the assessee doesn't get a notice before the deadline, there aren't any modifications the taxpayer needs to make.

What Are the Types of Errors That Come Under Section 143 (1) Of the Income Tax Act?

The aforementioned clause's subclause (vi) allows for adjustments to be made in light of additional income reported on Forms 26AS, 16A, or 16 but not taken into account when determining the return's total income. This section has been changed to (since the year 2018–19), no adjustment under sub clause (vi) would be made in relation to any returns that have been submitted. 
  • By removing the point of contact between the Assessee and the Assessing officer, making the best use of the available resources, and implementing an assessment which is team-based,  a new assessment scheme has been developed to promote greater openness and accountability. With effect from April 1, 2018, a new sub-section (3A) has been added to the law with the intent of allowing the government to specify the above mentioned new scheme for inquiry assessments by publication in the Official Gazette.
