Notification No. 01/2025 — Order under clause iia of sub section 1 of section 35 of the income tax act. 1961 read wit

What this is

Notification No. 01/2025 was published on 27 August 2025. Its subject is Order under clause iia of sub section 1 of section 35 of the income tax act. 1961 read with rule 5F of the income tax rules 1962 1.

This grants an exemption or a relief under a provision that allows one. Read the conditions attached: an exemption notification is construed strictly, and a condition missed is the exemption lost.

What it does

An order of the Principal Chief Commissioner of Income Tax (Exemptions), Delhi, under clause (iia) of sub-section (1) of section 35 of the Income-tax Act, 1961 read with rule 5F of the Income-tax Rules, 1962, according approval to IIT Madras Research Park (PAN AABCI5225P), Taramani, Chennai, for scientific research for the purposes of that clause. The approval is applicable from 1 April 2025 to 31 March 2030, that is for five assessment years from assessment year 2026-27 to assessment year 2030-31.

Who it reaches

IIT Madras Research Park, Chennai
Donors making payments to it and claiming deduction under section 35(1)(iia)
The Commissioner of Income-tax (Exemptions) having jurisdiction
Assessing Officers verifying such claims

The provisions it speaks to

Left, the provision of the Income-tax Act, 1961 as the instrument itself names it. Right, the section of the Income-tax Act, 2025 that the department’s own concordance maps it to — which is where the same ground is now covered.

The instrument, as the Board published it

The department publishes this one only as a PDF, so the words below were read out of that PDF by machine. That reading can carry its own mistakes — a misread number, a broken line. Check the signed document before you rely on a figure in it. The reading also stopped short of the end of the document: what is below is the opening, not the whole of it.

Explanatory Memorandum: It is certified that no person is being adversely affected by granting retrospective effect to this notification.

What it changes

The rule numbers are the 1962 Rules’ own, as the notification names them. The right-hand column is the department’s own mapping into the Income-tax Rules, 2026, which renumbered nearly everything.

Rule of the 1962 Rules	Now, in the 2026 Rules
Rule 5F	rule 35

From when

1 April 2025, retrospectively.

What to watch

The approval runs from 1 April 2025 to 31 March 2030, covering assessment years 2026-27 to 2030-31, and lapses thereafter unless renewed.
The Explanatory Memorandum certifies that no person is adversely affected by giving the notification retrospective effect, the order of 27 August 2025 operating from 1 April 2025.
Approval is conditioned on section 35(1)(iia) read with rule 5F, so the requirements of that rule continue to govern the approved company.
The address in the extract is partly garbled, so the company's particulars should be verified against the signed order.

Where you meet it

In a donor's claim of deduction under section 35(1)(iia) for a payment to the Research Park, and in the assessment where that claim is tested.

What it names

Rules it names. Rule 5F of the Income-tax Rules, 1962. The 1962 Rules were replaced by the Income-tax Rules, 2026, which renumbered nearly everything: a rule number quoted here almost never means the same rule today.

On the same provision

Other instruments in this library that name the same provision of the 1961 Act. They are not necessarily still operative, and a later one may have replaced an earlier one without saying so.

What a notification is. A notification is made under a power the Act itself gives, and within that power it is law — unlike a circular, which only binds the department. Its reach is the reach of the enabling provision and no wider, and the date it carries decides from when it works.
