Exemption under section 35AC extended for specified rural development projects through a notified scheme, enabling continued tax-deductible support. The Central Government specifies a multi-village rural development project carried out by Srinivasan Services Trust as an eligible project for tax exemption under section 35AC for a further three-year period, following prior notifications, expansion of project villages, and a recommendation by the National Committee, and does so without any change to the approved estimated cost.
