The Supreme Court of India has delivered a landmark ruling confirming that income tax reassessment proceedings are fundamentally void if the Assessing Officer fails to issue the mandatory notice under Section 143(2) of the Income Tax Act, 1961. In a consolidated judgment affecting multiple appeals, the bench of Justice Sanjay Kumar and Justice Sanjeev Sachdeva held that a taxpayer’s participation in reassessment inquiries does not cure the jurisdictional defect arising from the total absence of such a notice. The decision effectively bars the Income Tax Department from bypassing the statutory requirement to notify an assessee before initiating a scrutiny assessment.

The dispute reached the apex court after the Revenue attempted to defend reassessments conducted against Orissa Mining Corporation Ltd. and another taxpayer, Bijoy Kishore Mohanty, for several assessment years. While the original assessments for these parties had been completed under Section 143(3), the Revenue later sought to reopen these matters under Section 147 by issuing notices under Section 148. Crucially, while the department engaged in subsequent correspondence with the assessees under Section 142(1), it admittedly failed to issue the essential Section 143(2) notice in any of the cases.

Jurisdictional Prerequisite for Reassessment The court’s verdict underscores that the issuance of a notice under Section 143(2) is not merely a procedural formality but a foundational jurisdictional requirement. Without this notice, the Assessing Officer lacks the authority to frame an order under Section 143(3) as part of a reassessment process. The bench emphasized that the opportunity provided to an assessee to produce evidence or explain their tax position through the Section 143(2) notice is a critical safeguard.

As the court noted, “The Assessing Officer cannot undertake the proceedings of reassessment under Section 143(3), read with Section 147 of the Act, unless a notice under Section 143(2) of the Act has been issued to the Assessee. Mere participation of the Assessee in the assessment proceedings, in the absence of a notice under Section 143(2) of the Act, does not confer jurisdiction on the Assessing Officer to frame an assessment under Section 143(3) of the Act.”

The Revenue had argued that Section 292BB of the Income Tax Act—which creates a deeming fiction regarding the service of notices—should protect the proceedings. The department posited that since the taxpayers had actively participated and cooperated during the reassessment inquiries, they were precluded from raising objections regarding the lack of notice. However, the Supreme Court rejected this, clarifying that Section 292BB only addresses defects in service, such as delay, improper manner, or technical discrepancies, provided a notice was indeed issued by the department.

Limits of Deeming Fictions The bench clarified that Section 292BB cannot be used to conjure a notice where none exists. When the Revenue admits that no notice was sent, the statutory protection for the taxpayer remains absolute, and the department cannot hide behind the "cooperation" of the assessee to validate an inherently flawed proceeding. By drawing a sharp distinction between a notice that is "improperly served" and a notice that was "never issued," the court closed a significant loophole that tax authorities had frequently utilized to sustain questionable reassessment orders.

Furthermore, the court addressed the department's attempt to use correspondence under Section 142(1) as a substitute for the mandatory Section 143(2) notice. The department had claimed that by issuing letters seeking financial documents and stock information, it had essentially performed the functions intended by the notice. The Supreme Court dismissed this interpretation as legally unsustainable.

“A letter given by the Assessing Officer under section 142(1) of the Act during the course of reassessment proceedings would not satisfy the requirements of a notice under section 143(2) of the Act. A notice under section 143(2) of the Act is a sine qua non for commencing the proceedings. A letter issued after commencing the proceedings would not cover up the lacuna in the proceedings and would not validate what is non est,” the judgment observed.

Taxpayer Options Following Section 148 Notices The court also provided clarity on the process for taxpayers when they receive notices under Section 148, which invites them to file a return of income following a reopening notice. In the cases before the bench, some assessees had requested that their previously filed returns under Section 139 be treated as their returns in response to the Section 148 notices.

The Revenue had argued that this choice somehow waived the need for further scrutiny notices. The Supreme Court disagreed, affirming that a taxpayer’s choice to rely on an earlier return is a legitimate procedural option that does not, and cannot, relieve the tax authorities of their statutory burden. Regardless of whether a taxpayer submits a fresh return or chooses to stand by an earlier one, the Income Tax Department remains legally bound to issue a notice under Section 143(2) if it intends to conduct scrutiny.

Finality of the Ruling The decision relies heavily on the precedent set in Assistant Commissioner of Income Tax v. Hotel Blue Moon , which established that the failure to issue a Section 143(2) notice is not a "curable irregularity." By upholding the decisions of the Income Tax Appellate Tribunal and the High Court, the Supreme Court has set a clear standard for tax assessment practices moving forward.

The practical consequence of this judgment is that any current or future reassessment proceedings initiated without strict adherence to the notice requirement of Section 143(2) will be viewed as legally non-existent. The appeals filed by the Revenue were ultimately dismissed, as the court found no infirmity in the lower authorities' reasoning that the entire reassessment process had been vitiated by the absence of the mandatory notice. This ruling mandates that the Income Tax Department must ensure that all procedural checkboxes, particularly the issuance of notices, are verified before embarking on the task of reassessing established tax returns, ensuring that the rights of taxpayers are protected from arbitrary or procedurally defective actions.
