Section 270A

Authorities that bear on section 270A 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The Income-tax Act, 1961 was repealed on 1 April 2026.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 270A notice is

Penalty — Under-reporting / Mis-reporting. Penalty proposed for under-reporting or mis-reporting income. It is a critical-severity notice in the penalty family under the Income Tax Act 1961.

If you ignore it: Penalty levied. Immunity window may lapse.

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. ALWAYS check immunity u/s 270AA — see IMMUNITY below. It is time-barred and routinely missed.

Under the Income Tax Act 2025: section 439. But read that as reference, not as the provision to cite. 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.

Worked examples

Notice situations in which section 270A does the work, taken from the first line to the last. Each step carries the authority that licenses it.
A prosecution show-cause for two years where no return was filed The department wants to prosecute me for two years I never filed. I filed as soon as they asked, and all the tax was already paid by deduction and advance tax. How much trouble am I actually in? 8 steps · 15 authorities · s.276CC, s.278E, s.279, s.139(1) A return revised to bring in a survey surrender, and an officer who says it was never a valid revision We revised the return within time to bring in what was surrendered in a survey, and the officer now says s.139(5) does not cover a deliberate understatement and that the original return stands - how do we answer that? 9 steps · 40 authorities · s.139(5), s.133A, s.292C, s.139(1) A Rule 8D disallowance of Rs 1,12,40,000 against exempt income of Rs 6,40,000, and an earlier year with no exempt income at all The officer has disallowed under s.14A more than seventeen times the exempt income I actually earned, and he has done the same in a year where I earned none - how much of that survives, and does the 2022 amendment change the answer? 8 steps · 21 authorities · s.14A, s.14A(1), s.14A(2), s.14A(3) A running current account with the family company, and the peak debit of Rs 1,18,00,000 taxed as deemed dividend The officer has taxed the highest debit balance on our running account with the family company as deemed dividend under s.2(22)(e) in my hands, and made a protective addition of the same sum on the firm that actually received the money - how much of that survives? 7 steps · 23 authorities · s.2(22)(e), s.2(22), s.115-O, s.194 I sold my flat below the ready reckoner value - what is the taxable gain, and in which year The registrar valued my flat well above what I sold it for, I spent money on it over the years and I paid off my brother and my tenant. What is my capital gain, and does it fall in the year of the agreement or the year of the deed? 8 steps · 29 authorities · s.45, s.48, s.2(47), s.50C One flat, two additions: the buyer taxed on the gap and the seller taxed on the same gap We bought a flat below the ready reckoner rate and the department has added the difference to my income and substituted the same figure in my uncle's sale price.

Explained in this library

What section 270a 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?

Immunity from penalty and prosecution under s.270AA

The assessment added income and started penalty. Can I pay and buy immunity instead of fighting?

Interest under 234A, 234B, 234C and 244A

My order has three kinds of interest on top of the tax. What is each one for, and is it a penalty?

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.270A when the addition is nothing but a difference in valuation

The addition is the gap between my valuer's figure and the officer's. Can that be under-reporting, or misreporting?

s.271AAD: a penalty equal to the entry itself

The show-cause says I may be penalised under s.271AAD for a false entry. What is that, and is it really 100 per cent?

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?

Surcharge and cess

My tax bill has surcharge and cess on top of the tax — how are they worked out?

The 50 per cent and the 200 per cent: which limb of s.270A you are actually facing

The order proposes penalty under s.270A. Is it 50% or 200%, and what decides which?

The false-entry penalty is measured by the invoice, so cutting the addition does not cut it

The addition has been reduced to a profit element on appeal. Does the s.271AAD penalty come down with it?

The penalty that rides on a s.115BBE addition

The officer has taxed the cash at the special rate under s.115BBE. What penalty comes with it?

The two limbs of s.270A: fifty per cent, or two hundred

The penalty notice cites s.270A. What is the difference between under-reporting and misreporting, and which one is a stamp-value addition?

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 is actually deciding your faceless penalty, and what a hearing request is worth

The s.270A penalty is being run through the faceless machinery. Who is deciding it, and will I get a hearing if I ask?
