Amendment extends deduction eligibility from Indian companies to resident assessees other than companies, replaces Central Government references with the Board, adds a transitional proviso transferring pending and preserving prior approvals to the Board, and requires non-company/non-co-operative assessees to submit a prescribed auditor's report with their return based on an audit by an accountant as defined under the audit provision to claim the deduction.
