To apply for a PAN for a gratuity trust set up by a company, the application must be made in Form 49A under the category “Association of Persons (Trusts)”. The trust deed, along with the certificate of registration (if registered with any authority like EPFO or under Indian Trusts Act), and identity/address proof of the trust (e.g., registered office address proof, company resolution, etc.) must be submitted. Additionally, details of the authorized signatory (such as a trustee or principal officer) with their proof of identity and address are required. Since the gratuity trust seeks exemption under Section 10(25)(iv) of the Income-tax Act, a separate application for approval must be filed before the jurisdictional Principal Commissioner/Commissioner of Income Tax, supported by the trust deed and actuarial valuation. PAN is a prerequisite for such approval, and correct classification of the trust in the PAN application ensures regulatory compliance.
