Rule 288 of the Income-tax Rules, 2026

Rule 288 — Procedure for setting up an Infrastructure Debt Fund for purpose of exemption under Schedule VII [Table: Sl. No. 46] to Act. Made under s.263, s.162 of the Income-tax Act, 2025.

Where this rule sits

Rule 288 gives effect to Section 263 and Section 162 of the Income-tax Act, 2025. A rule cannot go beyond the section it serves: where the two seem to differ, the section governs.

What this rule does

Sub-rule (1) requires every Infrastructure Debt Fund under this rule to be set up as a Non-Banking Financial Company conforming to and satisfying the conditions laid down in the regulatory framework provided by the Reserve Bank of India.

Sub-rule (2) confines its investments to post commencement operation date infrastructure projects which have completed at least one year of satisfactory commercial operations, or to toll-operate-transfer projects as the direct lender.

Sub-rule (3) sets out, in a Table, the three permitted ways of raising funds and the conditions on each. Rupee denominated bonds or foreign currency bonds must be in accordance with the directions of the Reserve Bank of India and the relevant regulations under the Foreign Exchange Management (Transfer or Issue of Security by a Person Resident outside India) Regulations, 2000, and where the investor is a non-resident the original or initial maturity of the bond at the time of first investment by that investor must not be less than five years. Zero coupon bonds must be in accordance with rule 7 and carry the same five-year condition. Funds raised through the loan route under external commercial borrowings must be in accordance with the directions of the Foreign Exchange Department of the Reserve Bank of India, the tenor must not be less than five years, and the borrowings must not be sourced from foreign branches of Indian banks.

Sub-rule (4) caps investment in an individual project or a project belonging to a group at any time at 20% of the corpus of the fund. Sub-rule (5) bars investment in any project where the fund's specified shareholder, or the associated enterprise or the group of that specified shareholder, has a substantial interest.

Sub-rule (6) requires the fund to file its return of income as required by section 263(1)(a) on or before the due date specified in section 263(1)(c). Sub-rule (7) provides that if the fund does not fulfil any of the conditions in this rule or the directions of the Reserve Bank of India, all provisions of the Act apply as if it is not an Infrastructure Debt Fund referred to in Schedule VII [Table: Sl. No. 46].

Sub-rule (8) defines the terms: "associated enterprise" as in section 162; "concern" as in section 2(40); "corpus" as the total funds raised for the purpose of investment; "group" as in the Securities and Exchange Board of India (Mutual Funds) Regulations, 1996; substantial interest as beneficial ownership of shares carrying not less than 10% of the voting power in a company, or beneficial entitlement to not less than 20% of the income of a concern other than a company at any time during the tax year; "relative" by an eight-limb list; and "specified shareholder" as a non-banking financial company, a bank or any other person holding, directly or indirectly, shares carrying not less than 30% of the voting power in the Infrastructure Debt Fund.

Why it is there

Schedule VII [Table: Sl. No. 46] exempts income of an Infrastructure Debt Fund, and an exemption of that kind has to be fenced or it becomes a general vehicle for tax-free lending. The rule sets the fence on four sides: what the fund must be, being a Reserve Bank regulated Non-Banking Financial Company; what it may lend to, being operating infrastructure projects with a year's satisfactory commercial operation behind them, or toll-operate-transfer projects as direct lender; how it may raise money, with a five-year floor wherever the money comes from a non-resident; and how far it may concentrate, at 20% of corpus per project or group. Sub-rule (7) makes every one of those conditions load-bearing.

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.
WhatFigureThe condition on itWhere
Minimum operating history of a project the fund may invest inAt least one year of satisfactory commercial operationsPost commencement operation date infrastructure projects; the alternative is a toll-operate-transfer project as the direct lenderSub-rule (2)(a)

Substantial interest in a companyNot less than 10% of the voting powerBeneficial ownership of shares, other than shares entitled to a fixed rate of dividend, including holdings of relatives where the person is an individualSub-rule (8)(e)(i)
Substantial interest in a concern other than a companyNot less than 20% of the income of such concernBeneficial entitlement at any time during the tax yearSub-rule (8)(e)(ii)

Date for filing the return of incomeOn or before the due date specified in section 263(1)(c)The return required by section 263(1)(a); the rule points to the section and states no date of its ownSub-rule (6)

What this means in practice

The 20% cap in sub-rule (4) is tested at any time and against the group, not just the project, so a fund cannot reach the same borrower group through several projects, and a fall in corpus can put an existing exposure over the line without any fresh investment. The five-year floor is a floor on maturity or tenor, not a holding requirement on the investor, and for bonds it is measured at the time of the non-resident's first investment. The related-party bar in sub-rule (5) has a wide entry point: a specified shareholder is anyone holding, directly or indirectly, shares carrying not less than 30% of the voting power, and substantial interest reaches down to 10% of voting power in a company or 20% of the income of another concern, with a relative's holdings counted in for an individual. The consequence of failure is not a partial disallowance — sub-rule (7) provides that all the provisions of the Act apply as if the entity is not an Infrastructure Debt Fund referred to in Schedule VII [Table: Sl. No. 46] at all, and it is triggered equally by breach of the Reserve Bank's directions.

An example

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

An Infrastructure Debt Fund with a corpus of Rs. 500 crore may not have more than Rs. 100 crore invested at any time in one project or in projects belonging to one group. It issues rupee denominated bonds subscribed by a non-resident investor with an original maturity of six years, which satisfies the not-less-than-five-year condition. If it later lends to a project in which a shareholder holding 35% of its voting power holds 12% of the voting power, sub-rule (5) is breached and, under sub-rule (7), the Act applies to it as if it were not an Infrastructure Debt Fund at all.

Where you meet this rule

The fund meets this rule in its own Reserve Bank compliance and in the terms of every bond issue or external commercial borrowing it raises; a reader meets it in the fund's return filed under section 263(1)(a) and in any assessment testing whether the Schedule VII exemption survives.

The words themselves

The investment made by the Infrastructure Debt Fund in an individual project or project belonging to a group at any time, shall not exceed 20% of the corpus of the fund.
Rule 288(4), Income-tax Rules, 2026.
In case the Infrastructure Debt Fund does not fulfil any of the conditions provided in this rule or directions of the Reserve Bank of India, all provisions of the Act shall apply as if it is not an Infrastructure Debt Fund referred to in Schedule VII [Table: Sl. No. 46] to the Act.

What this page does not tell you. It does not reproduce the rule. Everything above was written from the rule’s own text as the Income Tax Department publishes it — the text is here. A rule is subordinate legislation: it prescribes the method, the form or the period, and it cannot enlarge the charge the section imposes. Where a figure matters, read the sub-rule it comes from.
