Sections 271AAA and 271AAB of the Income-tax Act, 1961 prescribe special penalties for undisclosed income detected in searches under section 132 during specified historical periods.

Section 271AAA - searches from 1 June 2007 to 30 June 2012
Meaning and scope. Section 271AAA applies where a search under section 132 was initiated on or after 1 June 2007 but before 1 July 2012. The Assessing Officer may direct payment of a penalty equal to 10% of the undisclosed income of the specified previous year, in addition to tax, if any.
Immunity under section 271AAA(2). The penalty under subsection (1) does not apply if, during the search, the assessee in a statement under section 132(4) admits the undisclosed income and specifies the manner in which it was derived, substantiates that manner, and pays the tax together with interest, if any, on that undisclosed income.
Interaction with other penalty provisions. Section 271AAA(3) prevents penalty under the former section 271(1)(c) in respect of the same undisclosed income covered by section 271AAA(1). Section 271AAA(4) makes sections 274 and 275 applicable, so far as may be, to proceedings under this section.
Definition of undisclosed income under section 271AAA
For section 271AAA, "undisclosed income" broadly includes income of the specified previous year represented wholly or partly by money, bullion, jewellery, another valuable article or thing, or an entry in books, documents or transactions found during the search which had not been recorded in the normal books or documents before the search or otherwise disclosed to the prescribed senior income-tax authority before the search. It also includes income represented by a false expense entry that would not have been found to be false but for the search.
Meaning of specified previous year under section 271AAA
The expression covers the previous year in which the search was conducted and, subject to the statutory conditions, an earlier previous year that had ended before the search where the due date under section 139(1) had not expired and the return had not been furnished before the search.
Section 271AAB - searches from 1 July 2012 to 31 August 2024
Section 271AAB is a special search-penalty provision. Its rate structure changed for searches initiated from 15 December 2016. Finance Act 2025 subsequently restricted subsection (1A) to searches initiated before 1 September 2024.
Section 271AAB(1): searches from 1 July 2012 to 14 December 2016
For the period governed by subsection (1), the section prescribed different rates depending on the assessee's conduct and satisfaction of statutory conditions. The concessional category required, among other matters, admission of undisclosed income in the section 132(4) statement, specification and substantiation of the manner in which it was derived, payment of tax and interest, and furnishing the return declaring the undisclosed income by the specified date. The provision also prescribed separate rates where income was not admitted during search but was declared and tax was paid by the specified date, and a higher residual rate for other cases.
Section 271AAB(1A): searches from 15 December 2016 to 31 August 2024
30% rate. A penalty equal to 30% of the undisclosed income of the specified previous year applies where the assessee, in the course of the search, admits the undisclosed income in a statement under section 132(4), specifies and substantiates the manner in which it was derived, and on or before the specified date pays tax with interest and furnishes the return declaring that undisclosed income.
60% rate. Where the case is not covered by the conditions for the 30% rate, section 271AAB(1A)(b) prescribes a penalty equal to 60% of the undisclosed income of the specified previous year.
No overlapping penalty on the same undisclosed income
Section 271AAB(2) provides that penalty under section 270A or the former section 271(1)(c), as applicable, shall not be imposed in respect of undisclosed income referred to in section 271AAB(1) or 271AAB(1A). Under subsection (3), sections 274 and 275 apply, as far as may be, to a penalty under section 271AAB.
Important definitions in section 271AAB
Specified date
The "specified date" is the due date for furnishing the return under section 139(1), or the date on which the period specified in the applicable notice for furnishing the return expires, as provided by the section for the relevant search regime.
Specified previous year
The expression generally covers the previous year in which the search was conducted and, where the statutory conditions are met, an earlier previous year that ended before the search for which the return-filing due date had not expired and the return had not been furnished before the search.
Undisclosed income
For section 271AAB, "undisclosed income" is a defined term. Broadly, it covers income of the specified previous year represented by money, bullion, jewellery, another valuable article or thing, or an entry in books, documents or transactions found in the search that was not recorded before the search in records maintained in the normal course or otherwise disclosed to the prescribed senior income-tax authority before the search. It also covers income represented by a false expense entry that would not have been detected as false without the search.
Searches on or after 1 September 2024
Finance Act 2025 amended section 271AAB(1A) by inserting the words "but before the 1st day of September, 2024". Consequently, section 271AAB is not the penalty provision for searches initiated on or after 1 September 2024. Under the revived block assessment framework in Chapter XIV-B of the Income-tax Act, 1961, section 158BFA provides for penalty in the circumstances specified there.
For searches initiated before 1 April 2026, the saving provisions of the Income-tax Act, 2025 may preserve application of the Income-tax Act, 1961 to the search and connected assessment, penalty and appeal proceedings. For searches initiated from 1 April 2026, the Income-tax Act, 2025 and the corresponding block assessment provisions should be consulted.
