Section 271(1)(c)

Authorities that bear on section 271(1)(c) 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The Income-tax Act, 1961 was repealed on 1 April 2026.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 271(1)(c) notice is

Penalty — Concealment (older years). Penalty proposed for concealing income or furnishing inaccurate particulars. It is a critical-severity notice in the penalty family under the Income Tax Act 1961.

If you ignore it: Penalty levied.

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. Check whether the notice specifies WHICH limb is alleged — concealment or inaccurate particulars. A notice that does not strike out the inapplicable limb is a well-known ground of challenge. Flag this for the CA every time.

Under the Income Tax Act 2025: there is no direct successor. Inoperative from AY 2017-18, replaced by s.270A. Superseded before the 2025 Act, so there is no direct successor. 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.

Explained in this library

What section 271(1)(c) does, in plain English, before you read what the courts made of it.

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?

s.270A and s.270AA: the statutory position

The assessment order says penalty under s.270A. What is that section, how is the amount worked out, and can I just pay and be done with it?

s.273B: the assessee proves the cause, and the list is closed

The officer says reasonable cause under s.273B is not available to me. Which penalties does the section actually reach, and who has to prove what?

s.274: the defective penalty notice

My penalty notice is a printed form and neither limb is struck out. Does that kill the penalty?
