Approval of investment fund eligibility secures tax benefits subject to Board conditions and withdrawal safeguards. An investment fund may apply in writing to the Board for approval of eligibility for the tax benefit under section 9A three months before the relevant previous year. A Board-notified committee of senior Income-tax authorities examines the application, may seek further information, and recommends grant, refusal or conditions. The Board must decide within sixty days of the application month to grant approval (subject to conditions) or reject it with reasons. Approval applies to the stated and subsequent previous years until withdrawn; withdrawal for misrepresentation, non-fulfilment of conditions or breach requires opportunity to be heard and communication of the order to the fund and relevant tax officers.
