Background of CIT v. Calcutta Discount Co.
The case CIT v. Calcutta Discount Co. (1973) is one of the most influential decisions in Indian tax jurisprudence concerning the duty of disclosure by the assessee, the meaning of “full and true disclosure,” and the scope of reassessment powers under Section 147 of the Income Tax Act. The dispute arose when the assessee-company, engaged mainly in share dealing, disclosed all primary facts in its return of income but did not explicitly highlight certain material effects of those facts. The assessing authority argued that the company suppressed vital information, thereby justifying reopening of assessment.
The core legal dilemma was whether the assessee must merely disclose primary facts or must additionally disclose the inferences that the assessing officer may draw. The Supreme Court’s interpretation of this issue significantly shaped Indian tax reassessment law and the extent of obligations on taxpayers.
Facts of the Case
Calcutta Discount Co. was engaged in the purchase and sale of shares. During assessment, it disclosed details relating to share transactions, including the quantities purchased, quantities sold, and resulting profits. However, the Income Tax Officer believed that by not explicitly stating that these were adventure in the nature of trade, the assessee had failed to make full and true disclosure.
The AO later sought to reopen the assessment under Section 34 of the 1922 Act (now Section 147 of the 1961 Act). The assessee challenged this reopening on the ground that all primary facts were properly disclosed, and the AO’s failure to draw correct inferences cannot justify reopening.
The High Court ruled in favour of the assessee, leading the Revenue to file an appeal before the Supreme Court.
Legal Issue
The central issue before the Supreme Court was:
Whether failure to disclose an inference or conclusion drawn from primary facts constitutes failure to disclose “material facts” for the purpose of reassessment under tax law?
In simpler terms, the question was whether taxpayers must not only disclose facts but also guide the tax department about what conclusions those facts lead to.

Arguments of the Parties
Revenue’s Stand
The Revenue argued that the assessee had concealed the true nature of the transactions by failing to reveal that they were speculative or business-oriented. It was claimed that mere disclosure of data did not amount to full disclosure unless the assessee also disclosed the inherent nature of the transaction.
Assessee’s Stand
The assessee argued that it had disclosed all primary facts, and it was not their legal duty to advise the assessing officer on what inferences he must draw. The assessee emphasized that the AO was already in possession of the necessary materials and failed to evaluate them properly during the original assessment.
Judgment of the Supreme Court
The Supreme Court delivered a landmark ruling in favour of the assessee, laying down important principles that still govern reassessment under Section 147.
Key Holding
The Court held that:
- The assessee’s duty is limited to disclosing primary facts.
- The assessee is not required to disclose what inferences the AO should draw.
- Reassessment cannot be justified merely because the AO initially failed to draw the proper inference from the available facts.
- Only if the assessee withheld primary material facts can reopening be justified.
The Supreme Court famously stated that once all primary facts are placed before the assessing officer, “the duty of the assessee ends, and it is for the officer to draw the correct inferences.”
This case continues to be cited extensively in reassessment jurisprudence and is often paired with later decisions like CIT v. Kelvinator of India (2010) which reiterated similar principles.
Importance in Income Tax Law
Clarifies the Scope of Disclosure
Before this judgment, the scope of “full and true disclosure” was ambiguous. The Court clarified that the assessee is not expected to act as a legal adviser to the department.
Limits Powers of Reassessment
This case prevents arbitrary and unlimited use of reopening powers. The AO cannot reopen an assessment simply because he committed an error earlier or wants a second chance.
Protects Taxpayers from Excessive Litigation
The ruling ensures that taxpayers are not continuously harassed by repeated reassessment notices due to departmental oversight.
Cited in Several Landmark Judgments
Cases like CIT v. Kelvinator (2010) and CIT v. Rajesh Jhaveri (2007) have referred to this decision to reinforce the difference between “change of opinion” and valid reassessment.
Strengthens Administrative Responsibility
The judgment makes it clear that the AO must perform his task properly during original assessment, as he cannot later reopen the case for his own oversight.
Application in Modern Tax Law
Under the Income Tax Act, 1961, Section 147 governs reassessment. The principles established in Calcutta Discount Co. continue to guide courts:
- Primary facts = must be disclosed.
- Secondary facts = AO’s responsibility.
- Legal inferences = AO’s responsibility.
- Reassessment requires tangible material, not mere change of opinion.
Courts regularly apply this rule when taxpayers challenge reopening under writ petitions.
Practical Impact for Tax Professionals
Why this Case Matters Today
Even after decades, the ruling remains highly relevant because reassessment is one of the most litigated areas in income tax law. Many reassessment notices are struck down because they violate the principles laid down in this case.
Real-World Scenarios Where It Applies
- In share trading or business transactions where disclosed facts are clear but interpretations vary.
- In cases where AO claims failure to disclose “nature” rather than “facts.”
- When AO reopens assessments alleging incomplete disclosure despite having full access to documents.
Academic Significance for Law Students
This case is part of the foundation of tax jurisprudence and must be studied along with Kelvinator (2010) and Rajesh Jhaveri (2007). It teaches:
- statutory interpretation,
- limitation on administrative power,
- taxpayer rights, and
- procedural fairness.
“A taxpayer must disclose facts, not guide the tax officer on how to think.”
