Enhancement by the CIT(A), and where it stops

Can the CIT(A) increase my assessment, and can he tax something the Assessing Officer never looked at?

The Income-tax Act, 1961 was repealed on 1 April 2026. It still governs income earned up to 31 March 2026, and every proceeding about those years however late — assessment, reassessment, rectification, penalty, revision and appeal alike. Income earned from 1 April 2026 is governed by the Income-tax Act, 2025. What changed, and which Act governs your year →

Can the CIT(A) increase my assessment, and can he tax something the Assessing Officer never looked at?

Section 251(1)(a) lets the CIT(A) confirm, reduce, enhance or annul, and section 251(2) requires a reasonable opportunity of showing cause before any enhancement. The powers are plenary and coterminous with the Assessing Officer's. But they stop at the boundary of the assessment: a source of income the officer never considered from the point of view of taxability cannot be brought in by enhancement.

This is an explainer, not a judgment. It states the law in our own words, which is exactly why it needs checking. Everything below was written from the sources listed at the foot of this page, and no chartered accountant has yet signed it off. Read the source before you rely on it in a reply or an appeal.

Three lines of authority have to be held together. First, the Supreme Court in Kanpur Coal Syndicate held that the first appellate authority has plenary powers, coterminous with those of the Assessing Officer, and can do what the officer can do and direct him to do what he failed to do. Second, section 251(2) prohibits enhancement without a reasonable opportunity of showing cause, so a notice of enhancement is a jurisdictional step and not a formality. Third, and most litigated, the Supreme Court in Shapoorji Pallonji Mistry and again in Rai Bahadur Hardutroy Motilal Chamaria confined the power to the subject-matter of the assessment - to sources of income considered expressly or by clear implication by the Assessing Officer from the point of view of taxability. Material sitting in the file that the officer never examined for taxability is not enough. Where a genuinely new source emerges, the Delhi High Court in Union Tyres held the route is reassessment under section 147/148 or revision under section 263, not enhancement, and the Full Bench in Sardari Lal & Co adopted the same reconciliation. The Revenue routinely cites Nirbheram Daluram (1997) for wider language; the accepted answer is that Nirbheram did not address the new-source question, so the restriction survives. Where enhancement is properly within the subject-matter - as where the additions are drawn from the assessee's own books and balance sheet already before the officer - it has been upheld. Practitioners go wrong by arguing only the merits of the proposed enhancement and never taking the jurisdictional objection, which is the ground most likely to succeed on further appeal.
