Section 263

Authorities that bear on section 263 of the Income-tax Act, 1961. Each one tells you what it decided and what to do if it applies to you.

The Income-tax Act, 1961 was repealed on 1 April 2026.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 →

Explained in this library

What section 263 does, in plain English, before you read what the courts made of it.

Can the Commissioner revise an intimation? The answer is not settled

My return was only processed under s.143(1) and never scrutinised. Can the Commissioner revise that under s.263?

Challenging a s.263 show-cause notice by writ, before the order

The Commissioner has issued a s.263 show-cause notice. Can I go to the High Court now, or do I have to wait for the order and appeal to the Tribunal?

Explanation 2 to s.263: no inquiry, against not enough inquiry

The s.263 notice says my assessment was passed 'without making inquiries or verification which should have been made'. What does that actually require the Commissioner to show?

How far the source-of-source enquiry can be pushed

The officer wants my lender's bank statements, and now his lender's. Where does this stop?

How long the department actually has to pass a penalty order

The penalty order has finally arrived, years after the assessment. Is it out of time under s.275?

Revision: s.263 against you, s.264 for you

The Commissioner has issued a notice to revise my assessment. Is that different from my asking him to revise it?

section 43B: deductions allowed only on actual payment

I keep my books on the mercantile basis and I have provided for GST, provident fund, a bonus and interest on my bank loan. The assessing officer has added all of it back because I had not paid it by 31 March. Can he do that, and do I lose the deduction for good?

What the CIT(A) has already decided, the Commissioner cannot revise

My assessment went to the CIT(A) on two issues. Can the Commissioner still revise it under s.263 on a third?

Which Act governs your year: the 1961 Act after 1 April 2026

I am holding a notice and I do not know whether my year is under the Income-tax Act, 1961 or the Income-tax Act, 2025. Which Act applies to me, and is the old Act still of any use now that it has been repealed?
