Charitable income exemption under Section 10(23C)(iv) shields receipts for Neo Sannyas Foundation subject to compliance conditions. Exemption applies to any income received by any person on behalf of Neo Sannyas Foundation provided the Institution applies or accumulates income exclusively for its objects (with limited accumulation beyond a specified threshold for a restricted period), confines investments to permitted modes, treats business income as taxable unless incidental with separate accounts, files returns, obtains a prescribed audit report, and on dissolution transfers surplus and assets to an organization with similar objectives; the notification covers recipients' receipts from assessment year 1999-2000 onwards and is rescindable for non-genuine activity or non-compliance.
