The Central Board of Direct Taxes (CBDT) has issued the Income-tax (Third Amendment) Rules, 2025, introducing crucial updates to Rule 2F of the Income-tax Rules, 1962. These amendments primarily impact Infrastructure Debt Funds (IDFs), outlining revised eligibility criteria, investment norms, and compliance requirements.

Key Highlights of the Amendment

Restricted Investment Scope
IDFs can now invest only in:- Infrastructure projects that have completed at least one year of successful commercial operations.
- Toll-Operate-Transfer (TOT) projects as direct lenders.
-
Fundraising Regulations
IDFs can raise funds through:- Rupee-denominated bonds or foreign currency bonds under RBI and FEMA guidelines.

Definition of "Specified Shareholder" Updated
The definition now includes NBFCs, banks, or any person holding at least 30% of voting power in an Infrastructure Debt Fund.
Implications for the Infrastructure Sector
The revised framework aims to:
