Section 171 of the Income-tax Act, 2025

Section 171 — Maintenance, keeping and furnishing of information and document by certain persons. Successor to s.92D of the 1961 Act.

Where this section sits

Section 171 is in Chapter X — Special Provisions Relating to Avoidance of Tax, which runs from section 161 to section 177.

← Section 170  ·  Section 172 →

What this section does

Sub-section (1) requires two classes of person — one who has entered into an international transaction or a specified domestic transaction, and one who is a constituent entity of an international group — to keep and maintain such information and document in respect of it, for such period and in such manner, as may be prescribed.

Sub-section (2) allows the Assessing Officer or the Commissioner (Appeals), during any proceeding under the Act, to require a person referred to in sub-section (1)(a) to furnish any of that information or document within ten days from the date of receipt of a notice issued in that regard. Sub-section (3) allows the same authority, on an application made by that person, to extend the ten days by a further period not exceeding thirty days.

Sub-section (4) requires every person referred to in sub-section (1)(b) — a constituent entity of an international group — to furnish the information and document to the authority prescribed under section 511(1), in such manner and on or before such date as may be prescribed. Sub-section (5) takes the meanings of "constituent entity" and "international group" from section 511(10)(d) and (g).

Why it is there

A transfer pricing or international group examination is only as good as the contemporaneous record behind it, and this section obliges the taxpayer to build and keep that record before any question is asked. The short ten-day period in sub-section (2) makes sense only on that footing: the documents are supposed to already exist, so the notice asks for production, not preparation.

Who it applies to

The figures, and what each one turns on

Read the condition in the same row. A figure quoted without it is a wrong answer with a citation attached.

Maximum extension of that periodA further period not exceeding thirty daysGranted by the Assessing Officer or the Commissioner (Appeals) on an application made by that person; the section fixes a ceiling, not an entitlementSub-section (3)

What this means in practice

The obligation to keep the record is unconditional and continuous, and it does not depend on any notice: sub-section (1) requires the information and document to be kept and maintained for the prescribed period in the prescribed manner. The production power in sub-section (2) is narrower than the keeping obligation — it reaches only a person within sub-section (1)(a), that is one who has entered into an international or specified domestic transaction, and only during a proceeding under the Act. A constituent entity's obligation runs the other way: sub-section (4) requires it to furnish the information to the authority prescribed under section 511(1) on or before a prescribed date, without waiting to be asked. The extension in sub-section (3) is a ceiling of thirty further days and is discretionary, so the longest the period can run is forty days from receipt, and only on an application actually made.

An example

Illustrative only, and invented for this page. The figures are chosen to show the rule biting, not taken from any real matter.

A company that has entered into an international transaction receives a notice under sub-section (2) on 5 May during a transfer pricing proceeding. The documents are due on 15 May. It applies for more time; the Assessing Officer may extend by up to thirty further days, so 14 June is the outer limit, and nothing in the section permits a longer period however voluminous the material. The company's separate obligation as a constituent entity, if it is one, is not affected — that filing runs to the prescribed authority under sub-section (4) on its own prescribed date.

Where you meet this section

You meet this section as the notice under sub-section (2) calling for transfer pricing documentation during an assessment or an appeal before the Commissioner (Appeals), and as the constituent entity filing to the authority prescribed under section 511(1).

What people get wrong

What this replaced

The correspondence is the Income Tax Department’s own, from its comparison utility for the 1961 and 2025 Acts. A renumbering is the easy half; whether the words changed is the half that decides cases.

Rules that serve this section

Rules of the Income-tax Rules, 2026 that work section 171. Where the rule’s own heading names the section we say so; the rest are marked on reading the rule, which is our derivation and not the department’s. A rule that serves the section silently and that we have missed will not appear here.

All of them are in the Rules 2026 index.

Circulars of the Board on this section

A circular binds the department, not you and not a court. Every one below was written under the 1961 Act; it reaches this section because the department’s own concordance carries the provision it names to this one.

See the circulars index.

Notifications that reach this section

A notification is made under a power the Act gives and, within that power, is law. These too were made under the 1961 Act and are placed here by the department’s concordance.

See the notifications index.

Case law carried across

Read this before you rely on it. Every decision below was decided under the Income-tax Act, 1961. It appears here because it is tagged to a 1961 provision that the department’s own mapping carries to section 171. That is an inference we have drawn, not a holding on the new section: where the words changed in the move, the reasoning may not survive. Treat this as the place to start looking, not as authority on the 2025 Act.
