Rule 2F: Infrastructure Debt Fund Guidelines and Section 10(47) Exemption
Rule 2F set out conditions for an Infrastructure Debt Fund (IDF) seeking the exemption associated with section 10(47) of the Income-tax Act, 1961. It addressed RBI regulation, eligible infrastructure investments, bond issuance, investment concentration and tax compliance.
Purpose and scope of Rule 2F
An Infrastructure Debt Fund is a financing vehicle intended to channel long-term capital to infrastructure projects. Under the historical section 10(47) framework, Rule 2F described the requirements applicable to an IDF established as a non-banking financial company (NBFC), including the relevant RBI regulatory conditions.
Eligibility for an income-tax exemption was conditional. Establishing an IDF or issuing infrastructure bonds did not, by itself, establish exemption from income tax.
Principal conditions under the historical rule
Regulated structure and eligible projects
The historical rule required the fund to be established as an NBFC complying with the RBI's 2011 IDF-NBFC directions. It restricted investment to specified infrastructure projects meeting operational requirements and referred to a tripartite agreement with the concessionaire and project authority.
Bond issuance and non-resident investment
Rupee-denominated or foreign-currency bonds were to be issued in accordance with RBI directions and applicable foreign-exchange regulations. The historical text included a minimum five-year initial maturity and three-year lock-in requirement for certain non-resident investments, subject to the transfer provision stated in the rule.
Concentration, related parties and returns
The reproduced version restricted exposure to a single project or project group to 20% of the fund corpus and barred investments where the sponsor or specified related parties had a substantial interest. It also referred to return filing under section 139(4C) and loss of the exemption treatment if prescribed conditions were not met.
