Application for registration of charitable or religious institutions uses Form No.10A with prescribed disclosures and attachments. Form No. 10A governs applications for registration, provisional registration, intimation or approval of charitable, religious and research institutions and requires detailed constitutional and identification data, disclosure of key persons and beneficial owners, financial statements and three-year income particulars where applicable, selection of category codes that trigger category-specific questions, and attachment of certified instruments, registration orders, audited accounts or NIL declarations; an authorised signatory must verify and undertake to notify any future alterations to the trust or institutional rules.
