Section 259 of the Income-tax Act, 2025

Section 259 — Power to call for information by prescribed income-tax authority. Successor to s.133C of the 1961 Act.

Where this section sits

Section 259 is in Chapter XIV — Tax Administration, which runs from section 236 to section 261.

← Section 258  ·  Section 260 →

What this section does

Sub-section (1) empowers a prescribed income-tax authority, for the purpose of verifying information already in its possession, to issue a notice requiring any person to furnish information useful for or relevant to any inquiry or proceeding under the Act, in the form and manner and within the time specified in the notice itself. Sub-section (2) allows that authority to process and utilise the information and documents received in accordance with the scheme notified under section 260. Sub-section (3) gives "proceeding" the meaning assigned to it in section 253.

Why it is there

It gives a designated authority a standing power to verify information it already holds by going directly to any person who can furnish it, without needing an assessment or other proceeding to be pending against that person. Routing the processing through the section 260 scheme keeps the use of what is collected within a notified framework.

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.

What this means in practice

A notice under this section can reach you even though nothing is pending in your own case, because the trigger is the authority's verification of information it already has. The form, manner and deadline are whatever the notice states, so the notice has to be read for its own terms rather than against any statutory period. What is furnished can be processed and used under the scheme notified under section 260, and the word "proceeding" carries the section 253 meaning rather than an ordinary one.

An example

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

The prescribed income-tax authority holds information about payments made by a firm against which nothing is pending, and issues a notice requiring the firm to furnish details of them in the form and manner the notice states and within the time it fixes — twenty-one days, say, the section itself laying down no period at all. The firm cannot answer that it is not under inquiry: sub-section (1) reaches “any person” whose information is useful for, or relevant to, any inquiry or proceeding under the Act, and the trigger is the authority's verification of information it already has. What is furnished may then be processed and used under the scheme notified under section 260.

Where you meet this section

As a notice under sub-section (1) from the prescribed income-tax authority, which can arrive whether or not any proceeding of your own is on foot. Everything about compliance — form, manner and deadline — has to be read off the notice itself, because the section fixes none.

The words themselves

such authority may issue a notice requiring any person to furnish any information as may be useful for, or relevant to, any inquiry or proceeding under this Act in such form and manner and within such time, as specified in such notice
Section 259(1), Income-tax Act, 2025.

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 259. 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.

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 259. 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.

Read with

What this page does not tell you. It does not reproduce the section. Everything above was written from the section’s own text as the Income Tax Department publishes it — the text is here, and nothing here is advice on your facts. Where a figure matters, read the sub-section it comes from.
