The Supreme Court of India has ruled that income tax reassessment proceedings cannot validly continue when the tax department has failed to issue the mandatory notice under Section 143(2) of the Income Tax Act, 1961.
In a judgment delivered on October 28, 2026, a Bench of Justices Sanjay Kumar and Sanjeev Sachdeva dismissed the Revenue’s appeals against decisions that had set aside reassessment proceedings involving Orissa Mining Corporation Ltd. and another taxpayer. The Court held that a taxpayer’s participation in the proceedings cannot compensate for the complete absence of the required notice.
Why Section 143(2) Notice Is Important
Section 143(2) provides for a notice requiring a taxpayer to produce evidence or particulars supporting their income tax return. It serves as an important procedural safeguard, giving taxpayers an opportunity to substantiate their claims during assessment.
The case concerned reassessments initiated after the tax department reopened earlier assessments under Section 147 and issued notices under Section 148. The taxpayers either filed returns or requested that their earlier returns be treated as returns submitted in response to the reopening notices.
However, the department did not issue the required notices under Section 143(2). The dispute reached the Supreme Court after the Income Tax Appellate Tribunal and the High Court ruled in favour of the taxpayers.
Taxpayer Participation Cannot Replace a Formal Notice
The Revenue argued that Section 292BB could protect the reassessment proceedings because the taxpayers had participated in the process without initially objecting to the missing notice.
The Supreme Court rejected this argument. Section 292BB deals with deemed service of notices when a taxpayer participates in proceedings, but the Court clarified that it cannot cure a situation in which the required notice was never issued in the first place.
The ruling also clarified two related issues:
An earlier income tax return: Asking the department to treat an original return filed under Section 139 as a return submitted in response to a Section 148 notice does not remove the requirement to issue a Section 143(2) notice.
A letter under Section 142(1): A letter requesting information or an explanation during reassessment cannot substitute for the mandatory notice under Section 143(2).
What the Judgment Means for Taxpayers
The decision reinforces the importance of following the prescribed procedure when reopening income tax assessments. The department must comply with mandatory notice requirements, and participation by a taxpayer does not automatically validate proceedings where a required notice was never issued.
The ruling may be relevant to taxpayers challenging reassessment orders on similar procedural grounds. However, it does not mean that every reassessment can be cancelled simply because a taxpayer disputes a notice. The specific facts, documents and applicable legal requirements must be examined in each case.
Taxpayers who receive reassessment communications should retain relevant notices, returns and correspondence and seek qualified advice if they believe a mandatory procedure has not been followed. Professional income tax consultant services can help taxpayers understand their filing obligations and assess tax-related documentation.
Supreme Court Dismisses Revenue Appeals
The Supreme Court found no reason to overturn the decisions of the Income Tax Appellate Tribunal and the High Court. It dismissed the Revenue’s appeals, affirming that Section 292BB does not remove the department’s obligation to issue a mandatory Section 143(2) notice.
The judgment provides further clarification on the distinction between defects in serving a notice and the complete failure to issue one. That distinction is central to determining whether the statutory requirements for reassessment have been met.
