Section 142(1)

Authorities that bear on section 142(1) 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The Income-tax Act, 1961 was repealed on 1 April 2026.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 →

What a section 142(1) notice is

Inquiry before Assessment. The officer is asking for information, accounts or a return. It is a medium-severity notice in the assessment family under the Income Tax Act 1961.

If you ignore it: Best judgment assessment and penalty exposure.

Time to reply: this notice type carries no standard period. The date is printed on the notice itself and you must read it off the document. Non-compliance can lead to best judgment assessment u/s 144 and penalty. Do not let this one sit.

Under the Income Tax Act 2025: not yet checked against the bare Act, so no number is stated here. The 2025 Act is a restructure, not a renumbering — s.232 and s.233 are tonnage tax, s.246 is discovery and summons, and s.148 is the inter-corporate dividend deduction, so a number cannot be guessed from the old one. Under s.536(2) of the 2025 Act, a proceeding for any tax year beginning before 1 April 2026 stays under the Income Tax Act 1961 from the notice through to the appeal — so a notice arriving today for an earlier year is a 1961 Act matter, whatever today's date is.

Winning the cross-examination point: when the addition goes and when the file just comes back

If I win the point that the statement was never given to me and the witness was never offered, does the addition go, or does the file come back for another round?
