Section 131 - Power Regarding Discovery, Production of Evidence, etc.
Case Laws & Commentary - Income-tax Act, 1961 (as amended by the Finance Act, 2026) - bharattax.co Treatise
Provision: Section 131 - confers on assessing/appellate and investigation authorities the powers of a civil court under the CPC (discovery and inspection, enforcing attendance and examination on oath, compelling production of documents, issuing commissions); sub-section (1A) empowers investigation authorities to exercise these powers even where no proceeding is pending; sub-section (3) - power to impound.
Chapter / Part: Chapter XIII, Part C - Powers.
FA 2026 status: Not amended by the Finance Act, 2026.
Nature: Core evidence-gathering power; closely linked to sections 132, 133A and 136. Frequently litigated on the pre-condition of a pending proceeding (sub-section (1)) and the independent investigation power (sub-section (1A)).
A. SECTION COMMENTARY
Civil-court powers, and their two gateways
Section 131 clothes the income-tax authorities with the powers of a civil court under the Code of Civil Procedure, 1908 in four respects: discovery and inspection; enforcing the attendance of any person and examining him on oath; compelling the production of books of account and other documents; and issuing commissions. These are powerful coercive tools, and the section provides two distinct gateways to them. Sub-section (1) makes the powers available to the Assessing Officer and other named authorities, but - on the settled construction - only when a proceeding is pending before the authority concerned. Sub-section (1A), inserted to strengthen the investigation wing, confers the same powers on the Principal Director General / Director General, Principal Director / Director, and other investigation authorities, and these may be exercised even where no proceeding is pending, if the authority has reason to suspect that income has been concealed.
The pending-proceeding requirement under sub-section (1)
The distinction matters greatly in practice. Under sub-section (1) the existence of a pending proceeding is a jurisdictional pre-condition: an Assessing Officer cannot issue a summons under section 131(1) when no assessment, appeal or other proceeding is actually pending before him, because the power is annexed to the conduct of such a proceeding (Jamnadas Madhavji). Where the Department wishes to make a pre-proceeding enquiry - typically at the investigation stage, before any return-related proceeding has commenced - it must travel through sub-section (1A), which is the provision specifically designed for that purpose. A summons that mis-describes its source, or that is issued under sub-section (1) when there is no pending proceeding, is vulnerable to challenge.
Statements on oath; impounding; and the link to section 136
A statement recorded under section 131 is taken on oath, and because section 136 deems proceedings before an income-tax authority to be judicial proceedings for the purposes of sections 193 and 228 of the Indian Penal Code (now the Bharatiya Nyaya Sanhita, 2023), a false statement attracts the perjury provisions. This gives a section 131 statement an evidentiary weight that a survey statement under section 133A (recorded without the power to administer oath) does not possess - a contrast the courts have repeatedly drawn. Sub-section (3) permits the authority to impound and retain books and documents produced before it, subject to recording reasons and the time-limits prescribed.
B. STATUTORY POSITION (verbatim text)
Reproduced below is section 131 as it stands in the bare Act.
131. (1) The Assessing Officer, Deputy Commissioner (Appeals), Joint Commissioner [, Joint Commissioner (Appeals)], Commissioner (Appeals), Principal Chief Commissioner or Chief Commissioner or Principal Commissioner or Commissioner and the Dispute Resolution Panel referred to in clause (a) of sub-section (15) of section 144C shall, for the purposes of this Act, have the same powers as are vested in a court under the Code of Civil Procedure, 1908 (5 of 1908), when trying a suit in respect of the following matters, namely :—
(a) discovery and inspection;
(b) enforcing the attendance of any person, including any officer of a banking company and examining him on oath;
(c) compelling the production of books of account and other documents; and
(d) issuing commissions.
(1A) If the Principal Director General or Director General or Principal Director or Director or Joint Director or Assistant Director or Deputy Director, or the authorised officer referred to in sub-section (1) of section 132 before he takes action under clauses (i) to (v) of that sub-section, has reason to suspect that any income has been concealed, or is likely to be concealed, by any person or class of persons, within his jurisdiction, then, for the purposes of making any enquiry or investigation relating thereto, it shall be competent for him to exercise the powers conferred under sub-section (1) on the income-tax authorities referred to in that sub-section, notwithstanding that no proceedings with respect to such person or class of persons are pending before him or any other income-tax authority.
(2) For the purpose of making an inquiry or investigation in respect of any person or class of persons in relation to an agreement referred to in section 90 or section 90A, it shall be competent for any income-tax authority not below the rank of Assistant Commissioner of Income-tax, as may be notified by the Board in this behalf, to exercise the powers conferred under sub-section (1) on the income-tax authorities referred to in that sub-section, notwithstanding that no proceedings with respect to such person or class of persons are pending before it or any other income-tax authority.
(3) Subject to any rules made in this behalf, any authority referred to in sub-section (1) or sub-section (1A) or sub-section (2) may impound and retain in its custody for such period as it thinks fit any books of account or other documents produced before it in any proceeding under this Act :
Provided that an Assessing Officer or an Assistant Director or Deputy Director shall not—
(a) impound any books of account or other documents without recording his reasons for so doing, or
(b) retain in his custody any such books or documents for a period exceeding fifteen days (exclusive of holidays) without obtaining the approval of the Principal Chief Commissioner or Chief Commissioner or Principal Director General or Director General or Principal Commissioner or Commissioner or Principal Director or Director therefor, as the case may be.

Cluster 1 - Sub-section (1): a pending proceeding is a pre-condition; sub-section (1A) for pre-proceeding enquiry
Jamnadas Madhavji & Co. v. J.B. Panchal, ITO (1986) 162 ITR 331 (Bom)
Forum / Citation: Bombay High Court, 31 March 1986. Reported: (1986) 162 ITR 331 (Bom).
Facts: The Income-tax Officer purported to exercise section 131(1) powers when no proceeding was pending before him.
Held: The powers under section 131(1) - discovery and inspection, enforcing attendance and examination on oath, compelling production of documents and issuing commissions - can be exercised only if a proceeding is actually pending before the officer concerned; 'proceeding' means one actually pending, not one completed or merely contemplated. Sub-section (1A) was introduced precisely to enable the higher investigation authorities to exercise these powers where no proceeding is pending.
Principle: Section 131(1) is annexed to a pending proceeding; pre-proceeding enquiry must travel through section 131(1A).
Relevance: The leading authority on the jurisdictional pre-condition to section 131(1).

Forum / Citation: Gujarat High Court, 2000. Reported: (2001) 248 ITR 55 (Guj).
Facts: Notices under section 131(1A) were issued after a search under section 132 had been completed; their validity was challenged.
Held: The power under section 131(1A) is available to the investigation authorities even after the completion of a search; it is logical and permissible to call for information after a search in order to obtain better particulars of, or a complete picture regarding, the material seized. The exercise of the power is not confined to the pre-search stage.
Principle: Section 131(1A) may be exercised before, during or after a search; it is not exhausted by the conduct of the search.
Relevance: Clarifies the temporal reach of the section 131(1A) investigation power.
Cluster 2 - Coercive power must be exercised strictly within the statute
Income-tax Officer v. Seth Brothers (1969) 74 ITR 836 (SC)
Forum / Citation: Supreme Court of India, 15 July 1969. Reported: (1969) 74 ITR 836 (SC); AIR 1970 SC 292; (1969) 2 SCC 324; (1970) 1 SCR 601.
Held: Coercive statutory powers (there, search under section 132; the principle applies equally to the civil-court powers under section 131) confer no arbitrary authority; they must be exercised strictly in accordance with the statute, and if challenged the officer must satisfy the court of the regularity of his action. Power exercised mala fide or for a collateral purpose is liable to be struck down.
Principle: The section 131 powers, being coercive, are confined to their statutory purpose and are amenable to judicial scrutiny.
Relevance: Supplies the standard of review for the exercise of section 131 powers.
Dr. Pratap Singh v. Director of Enforcement (1985) 155 ITR 166 (SC)
Forum / Citation: Supreme Court of India, 1985. Reported: (1985) 155 ITR 166 (SC); (1985) 22 Taxman 30; AIR 1985 SC 989; (1985) 3 SCC 72.
Held: The expression 'reason to believe' is not the same as the subjective satisfaction of the officer; the belief must be held in good faith and cannot be a mere pretence. The material grounding the belief may be secret or obtained through intelligence and need not be disclosed merely because its existence is denied; and an illegality in the method or initiation of a search does not, by itself, vitiate the evidence collected.
Principle: 'Reason to believe' requires a bona fide belief on some material; it is justiciable for good faith but the court does not substitute its own satisfaction.
Relevance: A leading statement of the 'reason to believe' standard common to sections 131(1A), 132 and 132A.
