Section 149

Authorities that bear on section 149 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The Income-tax Act, 1961 was repealed on 1 April 2026.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 149 does, in plain English, before you read what the courts made of it.

an assessment on a company that no longer exists, or on a dead person

Our transferor company merged into us and was dissolved, but the assessment order is still in its name — and separately, a section 148 notice has arrived in my late father's name. Is an order or notice on someone who does not exist simply void, or is it a mistake the department can put right?

An Insight risk category is information - but it is not the material

The only thing behind my s.148A show-cause is a high-risk category on the Insight portal. Is a portal flag "information" at all?

Limitation on notices and assessments

Is this notice too late, and does it matter that the officer had reasons?

No incriminating material, no addition — but only for the years that were already closed

The search turned up nothing for this year and the officer has still made an addition. Can he?

Service of notice

The department says it issued the notice, but I never got it — does that matter?

Signed on the 31st, sent on the 6th: when a s.148 notice is actually issued

My s.148 notice is dated 31 March but it only reached me in April. Which date does s.149 test?

The fifty lakh limb: what may be counted, and over how many years

The notice says more than Rs 50 lakh has escaped. What is the officer allowed to count towards that figure, and can he add up two years?

TOLA and the surviving time: working out the date your s.148 notice had to be issued by

My old s.148 notice was turned into a show-cause notice by Ashish Agarwal and a fresh s.148 notice came in 2022. How do I work out whether that fresh notice was in time?

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 Which Act applies to me, and is the old Act still of any use now that it has been repealed?

Who may issue the s.148 notice now: s.151A, s.147A and where the fight actually stands

Is the point that my ward officer issued the s.148 notice instead of the faceless unit still worth taking, and what happens if the assessment is already complete?
